Trends in prevalence of comorbidities in heart failure clinical trials

Effect of heart failure pharmacotherapies in patients with heart failure with mildly reduced ejection fraction

AIMS

The study sought to comprehensively investigate the effect of heart failure (HF) pharmacotherapies in patients with HF with mildly reduced ejection fraction (HFmrEF). In the absence of randomized controlled trials, guideline recommendations concerning HF-related therapies in patients with HFmrEF are limited.

METHODS AND RESULTS

Consecutive patients hospitalized with HFmrEF were retrospectively included at one institution from 2016 to 2022. The prognostic value of treatment with beta-blockers (BB), angiotensin-converting enzyme inhibitors, receptor blockers, or receptor-neprilysin inhibitor (ACEi/ARB/ARNI), mineralocorticoid receptor antagonists (MRA), and sodium-glucose-linked transport protein 2 inhibitors (SGLT2i) was investigated for all-cause mortality at 30 months (a median follow-up) and HF-related rehospitalization. A total of 2109 patients with HFmrEF were included. Treatment with BB [27.0 vs. 35.0%; hazard ratio (HR) = 0.737; 95% confidence interval (CI) 0.617-0.881; P = 0.001], ACEi/ARB/ARNI (25.9 vs. 37.6%; HR = 0.612; 95% CI 0.517-0.725; P = 0.001), and SGLT2i (11.9 vs. 29.5%; HR = 0.441; 95% CI 0.236-0.824; P = 0.010) was associated with a lower risk of 30-month all-cause mortality, which was still demonstrated after multivariable adjustment and propensity score matching. In contrast, MRA treatment was not associated with long-term prognosis. The risk of HF-related rehospitalization was not affected by HF pharmacotherapies. Finally, the lowest risk of long-term all-cause mortality was observed in patients with combined use of BB, ACEi/ARB/ARNI, and SGLT2i (HR = 0.456; 95% CI 0.227-0.916; P = 0.027).

CONCLUSION

Beta-blockers, ACEi/ARB/ARNI, and SGLT2i were independently associated with a lower risk of all-cause mortality in patients with HFmrEF, specifically when applied as combined 'HF triple therapy'. Randomized studies are needed to investigate the effect of HF-related pharmacotherapies in patients with HFmrEF.

Prevalence and prognosis of aortic valve diseases in patients hospitalized with heart failure with mildly reduced ejection fraction

AIMS

Data regarding the characterization and outcomes of patients with heart failure (HF) with mildly reduced ejection fraction (HFmrEF) is scarce. This study investigates the characteristics and prognostic impact of native aortic valve diseases (AVD) in patients with HFmrEF.

METHODS AND RESULTS

Consecutive patients hospitalized with HFmrEF (i.e. left ventricular ejection fraction 41-49% and signs and/or symptoms of HF) were retrospectively included at one institution from 2016 to 2022. The prognostic impact of native aortic valve stenosis (AS), aortic valve regurgitation (AR) and mixed AVD (MAVD) was investigated for the primary endpoint of long-term all-cause mortality during a median follow-up of 30 months. Kaplan-Meier, univariable and multivariable Cox proportional analyses were applied. From a total of 2106 patients hospitalized with HFmrEF, the prevalence of AS and AR was 16.5% and 31.2%, respectively (MAVD 7.8%). The presence of moderate/severe AS was associated with a higher risk of long-term all-cause mortality (44.8% vs. 28.7%; p = 0.001) and HF-related rehospitalization (18.6% vs. 12.0%; p = 0.001), even after multivariable adjustment (mortality: hazard ratio [HR] 1.320; 95% confidence interval [CI] 1.035-1.684; p = 0.025; HF-related rehospitalization: HR 1.570; 95% CI 1.101-2.241; p = 0.013). Interestingly, even mild AS was associated with increased risk of long-term all-cause mortality compared to patients without AS (HR 1.477; 95% CI 1.101-1.982; p = 0.009). In contrast, the presence of AR was not associated with long-term outcomes after multivariable adjustment.

CONCLUSIONS

The presence of AS, but not AR, was independently associated with increased risk of all-cause mortality and HF-related rehospitalization in patients with HFmrEF. Even milder stages of AS were associated with impaired prognosis.

Effect of anaemia and iron deficiency in heart failure with mildly reduced ejection fraction

OBJECTIVE

The present study aims to clarify the prevalence and prognostic impact of anaemia and iron deficiency in patients with heart failure with mildly reduced ejection fraction (HFmrEF).

BACKGROUND

The prognostic impact of anaemia and iron deficiency in HFmrEF has not yet been clarified.

METHODS

Consecutive patients with HFmrEF were retrospectively included at one institution from 2016 to 2022. Patients with anaemia (i.e. haemoglobin <13 g/dL in males and < 12 g/dL in females) were compared to patients without, respectively patients with or without iron deficiency. The primary endpoint was all-cause mortality at 30 months (median follow-up), secondary endpoints comprised HF-related rehospitalisation.

RESULTS

Two thousand one hundred and fifty four patients with HFmrEF with a median haemoglobin level of 12.2 g/dL were included. Anaemia was present in 52% of patients with HFmrEF and associated with a higher risk of all-cause mortality (44% vs. 18%; HR = 3.021; 95% CI 2.552-3.576; p =.001) and HF-related rehospitalisation (18% vs. 8%; HR = 2.351; 95% CI 1.819-3.040; p =.001) at 30 months, which was confirmed after multivariable adjustment. Although iron status was infrequently assessed in anaemics with HFmrEF (27%), the presence of iron deficiency was associated with higher risk of rehospitalisation for worsening HF (25% vs. 15%; HR = 1.746; 95% CI 1.024-2.976; p =.038), but not all-cause mortality (p =.279) at 30 months.

CONCLUSION

Anaemia and iron deficiency are very common in atleast half of patients with HFmrEF and independently associated with adverse long-term prognosis.

[Chronic kidney disease and chronic heart failure: impact on prognosis and choice of pathogenetic therapy]

AIM

To evaluate the impact of a decrease in glomerular filtration rate (GFR) on the prognosis of patients with chronic heart failure (CHF), to analyze real clinical practice regarding the frequency of prescribing pathogenetic therapy for CHF, achieving target dosages depending on the gradation of GFR in patients included in the CHF Register of the Tyumen region.

MATERIALS AND METHODS

The analysis included medical data of 4077 patients (1662 men and 2415 women) with NYHA class I-IV CHF who underwent examination and treatment in medical organizations of the Tyumen region for the period from January 2020 to May 2023. Criteria for inclusion in the register: proven heart failure. Chronic kidney disease (CKD) was assessed by GFR calculated using the CKD-EPI formula (ml/min/1.73 m2). The primary end point was defined as death from all causes.

RESULTS

GFR<60 ml/min/1.73 m2 was recorded in 34.6% of patients, more common in women (40.2 and 26.6%, respectively; p<0.001). When dividing patients into phenotypes according to LVEF, no statistically significant differences were found in the distribution of patients according to GFR. In patients with HFrEF and HFpEF GFR<45 ml/min/1.73 m2 was associated with an increased risk of meeting the endpoint. Analysis of prescribed pathogenetic therapy showed that in patients with HFrEF, the frequency of prescription of ACE inhibitors, â-blockers and MRA decreased (p=0.023, 006 and 0.01, respectively), and ARNI, on the contrary, increased with a decrease in GFR (p=0.026). In patients with HFpEF, a similar trend towards a decrease in the frequency of prescription of ACEIs and MCBs with a decrease in GFR (p<0.001) remained, but it was compensated by an inversely proportional increase in the frequency of prescription of ARBs (p<0.001). 100% of the target dosage is achieved in more than 90% of patients taking MRA across the entire LVEF range. While for â-blockers and ARNI/ACE/ARB the percentage of patients receiving the full therapeutic dosage of drugs is significantly lower. When analyzing target dosages of pathogenetic drugs, gradations of achieved doses were distributed evenly throughout the entire range of GFR.

CONCLUSION

GFR<60 ml/min/1.73 m2 occurs in every 3 patients with CHF across the entire range of LVEF. A decrease in GFR worsens the prognosis of patients with both HFrEF and HFpEF, increasing in direct proportion with the severity of the stage of CKD. Inclusion of patients in the monitoring program within the framework of the CHF service allows the treatment to be significantly brought closer to optimal drug therapy, at the same time, certain efforts are required to overcome difficulties with titration to target dosages.

Identifying Predictors of Heart Failure Readmission in Patients From a Statutory Health Insurance Database: Retrospective Machine Learning Study

BACKGROUND

Patients with heart failure (HF) are the most commonly readmitted group of adult patients in Germany. Most patients with HF are readmitted for noncardiovascular reasons. Understanding the relevance of HF management outside the hospital setting is critical to understanding HF and factors that lead to readmission. Application of machine learning (ML) on data from statutory health insurance (SHI) allows the evaluation of large longitudinal data sets representative of the general population to support clinical decision-making.

OBJECTIVE

This study aims to evaluate the ability of ML methods to predict 1-year all-cause and HF-specific readmission after initial HF-related admission of patients with HF in outpatient SHI data and identify important predictors.

METHODS

We identified individuals with HF using outpatient data from 2012 to 2018 from the AOK Baden-Württemberg SHI in Germany. We then trained and applied regression and ML algorithms to predict the first all-cause and HF-specific readmission in the year after the first admission for HF. We fitted a random forest, an elastic net, a stepwise regression, and a logistic regression to predict readmission by using diagnosis codes, drug exposures, demographics (age, sex, nationality, and type of coverage within SHI), degree of rurality for residence, and participation in disease management programs for common chronic conditions (diabetes mellitus type 1 and 2, breast cancer, chronic obstructive pulmonary disease, and coronary heart disease). We then evaluated the predictors of HF readmission according to their importance and direction to predict readmission.

RESULTS

Our final data set consisted of 97,529 individuals with HF, and 78,044 (80%) were readmitted within the observation period. Of the tested modeling approaches, the random forest approach best predicted 1-year all-cause and HF-specific readmission with a C-statistic of 0.68 and 0.69, respectively. Important predictors for 1-year all-cause readmission included prescription of pantoprazole, chronic obstructive pulmonary disease, atherosclerosis, sex, rurality, and participation in disease management programs for type 2 diabetes mellitus and coronary heart disease. Relevant features for HF-specific readmission included a large number of canonical HF comorbidities.

CONCLUSIONS

While many of the predictors we identified were known to be relevant comorbidities for HF, we also uncovered several novel associations. Disease management programs have widely been shown to be effective at managing chronic disease; however, our results indicate that in the short term they may be useful for targeting patients with HF with comorbidity at increased risk of readmission. Our results also show that living in a more rural location increases the risk of readmission. Overall, factors beyond comorbid disease were relevant for risk of HF readmission. This finding may impact how outpatient physicians identify and monitor patients at risk of HF readmission.

Characteristics and outcome of hospitalized patients with heart failure stratified for chronic kidney disease

AIMS

Heart failure (HF) and chronic kidney disease (CKD) place significant challenges on the healthcare system, and their co-existence is associated with shared adverse outcomes. The multinational CaReMe project was initiated to provide contemporary, real-world epidemiological data on cardiovascular and reno-metabolic diseases. Utilizing data from the German CaReMe cohort, we characterize a multicentric HF population and describe in-hospital outcomes stratified for co-morbid CKD.

METHODS AND RESULTS

This retrospective, observational study analysed administrative data from inpatient cases hospitalized in 87 German Helios hospitals between 1 January 2016 and 31 August 2022. The first hospitalization of patients aged ≥18 years with a primary discharge diagnosis of HF, based on ICD-10 codes, were considered the index cases, and subsequent hospitalizations were considered as readmissions. Baseline characteristics and outcomes were stratified for co-morbid CKD using ICD-10-encoding from the index cases. Cox regression was utilized for readmission endpoints and in-hospital mortality. In total, 174 829 index cases (mean age 79 ± 15 years, 49.9% female) were included; of these, 55.0% had coexisting CKD. Patients with CKD were older, suffered from worse HF-related symptoms, had a higher co-morbidity burden, and in-hospital mortality was increased at index and during follow-up. Prevalent CKD was associated with higher rehospitalization rates and was an independent predictor for in-hospital death.

CONCLUSIONS

Within this HF inpatient cohort from a multicentric German database, CKD was diagnosed in more than half of the patients and was associated with increased in-hospital mortality at baseline and during follow-up. Rehospitalizations were observed earlier and more frequently in patients with HF and co-morbid CKD.

US trends of in-hospital morbidity and mortality for acute myocardial infarctions complicated by cardiogenic shock

BACKGROUND

There is limited real-world data highlighting recent temporal in-hospital morbidity and mortality trends for cases of acute myocardial infarction complicated by cardiogenic shock. The role of mechanical circulatory support within this patient population remains unclear.

METHODS

The US National Inpatient Sample database was sampled from 2011 to 2018 identifying 206,396 hospitalizations with a primary admission diagnosis of ST- or Non-ST elevation myocardial infarction complicated by cardiogenic shock. The primary outcomes included trends of all-cause in-hospital mortality, mechanical circulatory support use, and sex-specific trends for acute myocardial infarction complicated by cardiogenic shock (AMI-CS) over the study period.

RESULTS

The annual number of AMI-CS hospitalizations increased from 22,851 in 2011 to 30,015 in 2018 and in-hospital mortality trends remained similar (42.9 % to 43.7 %, ptrend < 0.001). The proportion of patients receiving any temporary MCS device decreased (46.4 % to 44.4 %). The use of intra-aortic balloon pump (IABP) decreased (44.9 % to 32.9 %) and the use of any other non-IABP MCS device increased (2.5 % to 15.6 %), ptrend<0.001. Sex-specific mortality indicate female in-hospital mortality remained similar (50.3 % to 51 %, ptrend<0.001), but higher than male in-hospital mortality, which increased non-significantly (38.8 % to 40.2 %, ptrend = 0.372).

CONCLUSIONS

From 2011 to 2018, hospitalizations for AMI-CS patients have increased in number. However, there has been no recent appreciable change in AMI-CS mortality despite a changing treatment landscape with decreasing use of IABPs and increasing use of non-IABP MCS devices. Further research is necessary to examine the appropriate use of MCS devices within this population.

Enteral Access Outcomes in Patients Hospitalized With Cardiac Disease: A Retrospective Cohort Study

INTRODUCTION

Patients admitted with principal cardiac diagnosis (PCD) can encounter difficult inpatient stays that are often marked by malnutrition. In this setting, enteral feeding may improve nutritional status. This study examined the association of PCD with perioperative outcomes after elective enteral access procedures.

METHODS

Adult patients who underwent enteral access procedures between 2018 and 2020 at a tertiary care institution were reviewed retrospectively. Differences in baseline characteristics between patients with and without PCD were adjusted using entropy balancing. Multivariable logistic and linear regressions were subsequently developed to evaluate the association between PCD and nutritional outcomes, perioperative morbidity and mortality, length of stay, and nonelective readmission after enteral access.

RESULTS

912 patients with enteral access met inclusion criteria, of whom 84 (9.2%) had a diagnosis code indicating PCD. Compared to non-PCD, patients with PCD more commonly received percutaneous endoscopic gastrostomy by general surgery and had a higher burden of comorbidities as measured by the Charlson comorbidity index. Multivariable risk adjustment generated a strongly balanced distribution of baseline covariates between patient groups (standardized differences ranged from -2.45 × 10-8 to 3.18 × 108). After adjustment, despite no significant association with in-hospital mortality, percentage change prealbumin, length of stay, or readmission, PCD was associated with an approximately 2.25-day reduction in time to meet goal feeds (95% CI -3.76 to -0.74, P = 0.004) as well as decreased odds of reoperation (adjusted odds ratio 0.28, 95% CI 0.09-0.86, P = 0.026) and acute kidney injury (adjusted odds ratio 0.24, 95% CI 0.06-0.91, P = 0.035).

CONCLUSIONS

Despite having more comorbidities than non-PCD, adult enteral access patients with PCD experienced favorable nutritional and perioperative outcomes.

Non-cardiac comorbidities in heart failure: an update on diagnostic and management strategies

Managing non-cardiac comorbidities in heart failure (HF) requires a tailored approach that addresses each patient's specific conditions and needs. Regular communication and coordination among healthcare providers is crucial to providing the best possible care for these patients. Poorly controlled hypertension contributes to left ventricular remodeling and diastolic dysfunction, emphasizing the importance of optimal blood pressure control while avoiding adverse effects. Among HF patients with diabetes, SGLT2 inhibitors and mineralocorticoid receptor antagonists have shown promise in reducing HF-related morbidity and mortality. Chronic kidney disease exacerbates HF and vice versa, forming the vicious cardiorenal syndrome, so disease-modifying therapies should be maintained in HF patients with comorbid CKD, even with transient changes in kidney function. Anemia in HF patients may be multifactorial, and there is growing evidence for the benefit of intravenous iron supplementation in HF patients with iron deficiency with or without anemia. Obesity, although a risk factor for HF, paradoxically offers a better prognosis once HF is established, though developing treatment strategies may improve symptoms and cardiac performance. In HF patients with stroke and atrial fibrillation, anticoagulation therapy is recommended. Among HF patients with sleep-disordered breathing, continuous positive airway pressure may improve sleep quality. Chronic obstructive pulmonary disease often coexists with HF, and many patients can tolerate cardioselective beta-blockers. Cancer patients with comorbid HF require careful consideration of cardiotoxicity risks associated with cancer therapies. Depression is underdiagnosed in HF patients and significantly impacts prognosis. Cognitive impairment is prevalent in HF patients and impacts their self-care and overall quality of life.

The role of multimorbidity in patients with heart failure across the left ventricular ejection fraction spectrum: Data from the Swedish Heart Failure Registry

AIMS

The aim of this analysis was to provide data on the overall comorbidity burden, both cardiovascular (CV) and non-CV, in a large real-world heart failure (HF) population across the ejection fraction (EF).

METHODS AND RESULTS

Patients with HF from the Swedish HF Registry between 2000 and 2021 were included. Of 91 463 patients (median age 76 years [interquartile range 67-82]), 98% had at least one among the 17 explored comorbidities (94% at least one CV and 85% at least one non-CV comorbidity). All comorbidities, except for coronary artery disease (CAD), were more frequent in HF with preserved EF (HFpEF). Patients with multiple comorbidities were older, more likely female, inpatients, with HFpEF, worse New York Heart Association class and higher N-terminal pro-B-type natriuretic peptide levels. In a multivariable Cox model, 12 comorbidities were independently associated with a higher risk of death from any cause. The highest risk was associated with dementia (hazard ratio [HR] 1.55, 95% confidence interval [CI] 1.45-1.65), chronic kidney disease (HR 1.37, 95% CI 1.34-1.41), chronic obstructive pulmonary disease (HR 1.32, 95% CI 1.28-1.35). Obesity was associated with a lower risk of all-cause death (HR 0.81, 95% CI 0.79-0.84). CAD and valvular heart disease were associated with a higher risk of all-cause and CV mortality, but not non-CV mortality, whereas cancer and musculo-skeletal disease increased the risk of non-CV mortality. A significant interaction with EF was observed for several comorbidities. Occurrence of CV and non-CV outcomes was related to the number of CV and non-CV comorbidities, respectively.

CONCLUSION

The burden of both CV and non-CV comorbidities was high in HF regardless of EF, but overall higher in HFpEF. Multimorbidity was associated with a high risk of death with a different burden on CV or non-CV outcomes.

Sudomotor dysfunction is associated with impaired left ventricular diastolic function in persons with type 2 diabetes: a cross-sectional study

BACKGROUND

The incidence of preserved ejection fraction heart failure has significantly increased in persons with type 2 diabetes mellitus (T2DM). Left ventricular (LV) diastolic dysfunction is an early and important manifestation of preserved ejection fraction heart failure. The onset of heart failure in persons with diabetes is associated with diabetic neuropathy. However, the relationship among sudomotor function, which is an early manifestation of small fiber neuropathy, and LV diastolic function remains unclear. This study aimed to explore the association between sudomotor function and LV diastolic function in persons with T2DM.

METHODS

In total, 699 persons with T2DM were enrolled and divided into three groups according to electrochemical skin conductance (ESC) assessed using the SUDOSCAN device: "no dysfunction" group (NSF), "moderate dysfunction" group (MDF), and "severe dysfunction" group (SDF). LV diastolic function was assessed using Doppler echocardiography. To evaluate the relationship between ESC and echocardiographic parameters, Pearson's correlation analysis was performed. Additionally, logistic regression analysis was used to determine the association between LV diastolic function and ESC. A receiver operating characteristic (ROC) curve was constructed to evaluate the performance of sudomotor function indicators in detecting impaired cardiac diastolic function.

RESULTS

There were 301 persons (43.06%) in the NSF group, 232 (33.19%) in the MDF group, and 166 (23.75%) in the SDF group. Compared to the NSF group, the MDF and SDF groups had higher A and E/e' and lower e' values (all p < 0.05). Pearson's correlation analysis showed that A and E/e' were negatively associated with foot ESC (FESC) and hand ESC (HESC), whereas e' was positively associated with FESC and HESC (all p < 0.05). After adjusting for confounding factors, binary logistic regression analysis showed that ESC was independently associated with impaired LV diastolic function (p = 0.003). The area under the ROC curve values for FESC and HESC were 0.621 and 0.635, respectively (both p < 0.05).

CONCLUSIONS

Deteriorating sudomotor function was associated with reduced diastolic function indicators. ESC can be used as a biomarker for detecting LV diastolic impairment.

Trends and Outcomes of Combined Heart-Kidney and Heart-Lung Transplantation Over the Past Two Decades

INTRODUCTION

Combined heart-kidney transplantation (HKTx) and combined heart-lung transplantation (HLTx) remain the definitive therapy for patients with end-stage heart failure with concomitant end-stage renal or lung failure. We sought to study trends and outcomes of HKTx and HLTx over the last two decades.

METHODS

The United Network for Organ Sharing registry was used to identify all adult patients (aged >18 y) who underwent HKTx and HLTx between 2001 and 2021. Patients were divided into 5-y groups by the year of transplantation (2001-2006, 2007-2011, 2012-2016, and 2017-2021). Primary outcome was 1-y posttransplantation mortality. Kaplan-Meier and multivariable Cox proportional hazards models were used for unadjusted and risk-adjusted survival analyses, respectively.

RESULTS

A total of 2301 HKTx and 567 HLTx patients were included. Between 2001 and 2021, HKTx volume increased from 25 to 344 patients (P < 0.001) and centers performing HKTx increased from 19 to 76 (P < 0.001). On unadjusted analysis, 1-y survival after HKTx improved from 86.7% in 2001-2006 to 89.0% in 2017-2021 (log-rank, P = 0.005). On risk-adjusted analysis, the hazard ratio of 1-y mortality for 2017-2021 was 0.62 (0.39-1.00, P = 0.048) compared with that for 2001-2006. Between 2001 and 2021, HLTx volume increased from 21 to 43 patients (P < 0.001) and centers performing HLTx increased from 12 to 20 (P = 0.047). On unadjusted analysis, 1-y survival after HLTx improved from 68.9% in 2001-2006 to 83.9% in 2017-2021 (log-rank, P = 0.600). On risk-adjusted analysis, the hazard ratio of 1-y mortality for 2017-2021 was 0.37 (0.21-0.67, P = 0.001) compared with that for 2001-2006.

CONCLUSIONS

Over the last two decades, HKTx volume substantially increased and HLTx experienced resurgent growth. One-year survival persistently improved for both procedures, especially over the past 5 y.

Heart Failure with Preserved Ejection Fraction: How to Deal with This Chameleon

Heart failure with preserved ejection fraction (HFpEF) is characterized by a notable heterogeneity in both phenotypic and pathophysiological features, with a growing incidence due to the increase in median age and comorbidities such as obesity, arterial hypertension, and cardiometabolic disease. In recent decades, the development of new pharmacological and non-pharmacological options has significantly impacted outcomes, improving clinical status and reducing mortality. Moreover, a more personalized and accurate therapeutic management has been demonstrated to enhance the quality of life, diminish hospitalizations, and improve overall survival. Therefore, assessing the peculiarities of patients with HFpEF is crucial in order to obtain a better understanding of this disorder. Importantly, comorbidities have been shown to influence symptoms and prognosis, and, consequently, they should be carefully addressed. In this sense, it is mandatory to join forces with a multidisciplinary team in order to achieve high-quality care. However, HFpEF remains largely under-recognized and under-treated in clinical practice, and the diagnostic and therapeutic management of these patients remains challenging. The aim of this paper is to articulate a pragmatic approach for patients with HFpEF focusing on the etiology, diagnosis, and treatment of HFpEF.

Harmony in Chaos: Deciphering the Influence of Ischemic Cardiomyopathy and Non-Cardiac Comorbidities on Holter ECG Parameters in Chronic Heart Failure Patients: A Pilot Study

Background and Objective: In the landscape of heart failure, non-cardiac comorbidities represent a formidable challenge, imparting adverse prognostic implications. Holter ECG monitoring assumes a supplementary role in delineating myocardial susceptibility and autonomic nervous system dynamics. This study aims to explore the potential correlation between Holter ECG parameters and comorbidities in individuals with ischemic cardiomyopathy experiencing heart failure (HF), with a particular focus on the primary utility of these parameters as prognostic indicators. Materials and Methods: In this prospective inquiry, a cohort of 60 individuals diagnosed with heart failure underwent stratification into subgroups based on the presence of comorbidities, including diabetes, chronic kidney disease, obesity, or hyperuricemia. Upon admission, a thorough evaluation of all participants encompassed echocardiography, laboratory panel analysis, and 24 h Holter monitoring. Results: Significant associations were uncovered between diabetes and unconventional physiological indicators, specifically the Triangular index (p = 0.035) and deceleration capacity (p = 0.002). Pertaining to creatinine clearance, notable correlations surfaced with RMSSD (p = 0.026), PNN50 (p = 0.013), and high-frequency power (p = 0.026). An examination of uric acid levels and distinctive Holter ECG patterns unveiled statistical significance, particularly regarding the deceleration capacity (p = 0.045). Nevertheless, in the evaluation of the Body Mass Index, no statistically significant findings emerged concerning Holter ECG parameters. Conclusions: The identified statistical correlations between non-cardiac comorbidities and patterns elucidated in Holter ECG recordings underscore the heightened diagnostic utility of this investigative modality in the comprehensive evaluation of individuals grappling with HF. Furthermore, we underscore the critical importance of the thorough analysis of Holter ECG recordings, particularly with regard to subtle and emerging parameters that may be overlooked or insufficiently acknowledged.

Enhancing heart failure treatment decisions: interpretable machine learning models for advanced therapy eligibility prediction using EHR data

Timely and accurate referral of end-stage heart failure patients for advanced therapies, including heart transplants and mechanical circulatory support, plays an important role in improving patient outcomes and saving costs. However, the decision-making process is complex, nuanced, and time-consuming, requiring cardiologists with specialized expertise and training in heart failure and transplantation. In this study, we propose two logistic tensor regression-based models to predict patients with heart failure warranting evaluation for advanced heart failure therapies using irregularly spaced sequential electronic health records at the population and individual levels. The clinical features were collected at the previous visit and the predictions were made at the very beginning of the subsequent visit. Patient-wise ten-fold cross-validation experiments were performed. Standard LTR achieved an average F1 score of 0.708, AUC of 0.903, and AUPRC of 0.836. Personalized LTR obtained an F1 score of 0.670, an AUC of 0.869 and an AUPRC of 0.839. The two models not only outperformed all other machine learning models to which they were compared but also improved the performance and robustness of the other models via weight transfer. The AUPRC scores of support vector machine, random forest, and Naive Bayes are improved by 8.87%, 7.24%, and 11.38%, respectively. The two models can evaluate the importance of clinical features associated with advanced therapy referral. The five most important medical codes, including chronic kidney disease, hypotension, pulmonary heart disease, mitral regurgitation, and atherosclerotic heart disease, were reviewed and validated with literature and by heart failure cardiologists. Our proposed models effectively utilize EHRs for potential advanced therapies necessity in heart failure patients while explaining the importance of comorbidities and other clinical events. The information learned from trained model training could offer further insight into risk factors contributing to the progression of heart failure at both the population and individual levels.

Associations between cardiometabolic multimorbidity and cerebrospinal fluid biomarkers of Alzheimer's disease pathology in cognitively intact adults: the CABLE study

BACKGROUND

Cardiometabolic multimorbidity is associated with an increased risk of dementia, but the pathogenic mechanisms linking them remain largely undefined. We aimed to assess the associations of cardiometabolic multimorbidity with cerebrospinal fluid (CSF) biomarkers of Alzheimer's disease (AD) pathology to enhance our understanding of the underlying mechanisms linking cardiometabolic multimorbidity and AD.

METHODS

This study included 1464 cognitively intact participants from the Chinese Alzheimer's Biomarker and LifestylE (CABLE) database. Cardiometabolic diseases (CMD) are a group of interrelated disorders such as hypertension, diabetes, heart diseases (HD), and stroke. Based on the CMD status, participants were categorized as CMD-free, single CMD, or CMD multimorbidity. CMD multimorbidity is defined as the coexistence of two or more CMDs. The associations of cardiometabolic multimorbidity and CSF biomarkers were examined using multivariable linear regression models with demographic characteristics, the APOE ε4 allele, and lifestyle factors as covariates. Subgroup analyses stratified by age, sex, and APOE ε4 status were also performed.

RESULTS

A total of 1464 individuals (mean age, 61.80 years; age range, 40-89 years) were included. The markers of phosphorylated tau-related processes (CSF P-tau181: β = 0.165, P = 0.037) and neuronal injury (CSF T-tau: β = 0.065, P = 0.033) were significantly increased in subjects with CMD multimorbidity (versus CMD-free), but not in those with single CMD. The association between CMD multimorbidity with CSF T-tau levels remained significant after controlling for Aβ42 levels. Additionally, significantly elevated tau-related biomarkers were observed in patients with specific CMD combinations (i.e., hypertension and diabetes, hypertension and HD), especially in long disease courses.

CONCLUSIONS

The presence of cardiometabolic multimorbidity was associated with tau phosphorylation and neuronal injury in cognitively normal populations. CMD multimorbidity might be a potential independent target to alleviate tau-related pathologies that can cause cognitive impairment.

Prognostic Implications of Type 2 Diabetes Mellitus in Heart Failure with Mildly Reduced Ejection Fraction

BACKGROUND

Data regarding the characterization and outcomes of diabetics with heart failure with a mildly reduced ejection fraction (HFmrEF) is scarce. This study investigates the prevalence and prognostic impact of type 2 diabetes in patients with HFmrEF.

METHODS

Consecutive patients with HFmrEF (i.e., left ventricular ejection fraction 41-49% and signs and/or symptoms of HF) were retrospectively included at one institution from 2016 to 2022. Patients with type 2 diabetes (dia-betics) were compared to patients without (i.e., non-diabetics). The primary endpoint was all-cause mortality at 30 months. Statistical analyses included Kaplan-Meier, multivariable Cox regression analyses and propensity score matching.

RESULTS

A total of 2169 patients with HFmrEF were included. The overall prevalence of type 2 diabetes was 36%. Diabetics had an increased risk of 30-months all-cause mortality (35.8% vs. 28.6%; HR = 1.273; 95% CI 1.092-1.483; p = 0.002), which was confirmed after multivariable adjustment (HR = 1.234; 95% CI 1.030-1.479; p = 0.022) and propensity score matching (HR = 1.265; 95% CI 1.018-1.572; p = 0.034). Diabetics had a higher risk of HF-related rehospitalization (17.8% vs. 10.7%; HR = 1.714; 95% CI 1.355-2.169; p = 0.001). Finally, the risk of all-cause mortality was increased in diabetics treated with insulin (40.7% vs. 33.1%; log-rank p = 0.029), whereas other anti-diabetic pharmacotherapies had no prognostic impact in HFmrEF.

CONCLUSIONS

Type 2 diabetes is common and independently associated with adverse long-term prognosis in patients with HFmrEF.

Shared and Reciprocal Mechanisms Between Heart Failure and Cancer - An Emerging Concept of Heart-Cancer Axis

Epidemiological evidence of increased risks of cancer in heart failure (HF) patients and HF in cancer patients has suggested close relationships between the pathogenesis of both diseases. Indeed, HF and cancer share common risk factors, including aging and unhealthy lifestyles, and underlying mechanisms, including activation of the sympathetic nervous system and renin-angiotensin-aldosterone system, chronic inflammation, and clonal hematopoiesis of indeterminate potential. Mechanistically, HF accelerates cancer development and progression via secreted factors, so-called cardiokines, and epigenetic remodeling of bone marrow cells into an immunosuppressive phenotype. Reciprocally, cancer promotes HF via cachexia-related wasting and metabolic remodeling in the heart, and possibly via cancer-derived extracellular vesicles influencing myocardial structure and function. The novel concept of the "heart-cancer axis" will help in our understanding of the shared and reciprocal relationships between HF and cancer, and provide innovative diagnostic and therapeutic approaches for both diseases.

Diagnostic and Prognostic Value of Aminoterminal Prohormone of Brain Natriuretic Peptide in Heart Failure with Mildly Reduced Ejection Fraction Stratified by the Degree of Renal Dysfunction

Limited data concerning the diagnostic and prognostic value of blood-derived biomarkers in heart failure with mildly reduced ejection fraction (HFmrEF) is available. This study investigates the diagnostic and prognostic value of aminoterminal prohormone of brain natriuretic peptide (NT-proBNP) in patients with HFmrEF, stratified by the estimated glomerular filtration rate (eGFR). Consecutive patients with HFmrEF were retrospectively included at one institution from 2016 to 2022. First, the diagnostic value of NT-proBNP for acute decompensated heart failure (ADHF) was tested. Thereafter, the prognostic value of NT-proBNP levels was tested for 30-months all-cause mortality in patients with ADHF. From a total of 755 patients hospitalized with HFmrEF, the rate of ADHF was 42%. Patients with ADHF revealed higher NT-proBNP levels compared to patients without (median 5394 pg/mL vs. 1655 pg/mL; p = 0.001). NT-proBNP was able to discriminate ADHF with an area under the curve (AUC) of 0.777 (p = 0.001), with the highest AUC in patients with eGFR ≥ 60 mL/min (AUC = 0.800; p = 0.001), and no diagnostic value was seen in eGFR < 30 mL/min (AUC = 0.576; p = 0.210). Patients with NT-proBNP levels > 3946 pg/mL were associated with higher rates of all-cause mortality at 30 months (57.7% vs. 34.4%; HR = 2.036; 95% CI 1.423-2.912; p = 0.001), even after multivariable adjustment (HR = 1.712; 95% CI 1.166-2.512; p = 0.006). In conclusion, increasing NT-proBNP levels predicted the risk of ADHF and all-cause mortality in patients with HFmrEF and preserved renal function; however, NT-proBNP levels were not predictive in patients with HFmrEF and eGFR < 30 mL/min.

A contemporary update on cancer and takotsubo syndrome

Takotsubo syndrome (TTS) is characterized by a transient left ventricular systolic dysfunction, burdened by significant acute and long-term mortality and morbidity. The prognosis of TTS, especially in the long-term, is influenced by both non-cardiovascular (non-CV) and CV comorbidities, among which cancer is one of the most common. The presence of a malignancy is proven to be associated with higher mortality in TTS. Moreover, a number of anticancer treatments has been reported to possibly cause TTS as a form of cardiotoxicity, even though clearcut associations are lacking. The aim of this narrative review is to sum up contemporary knowledge on the association of cancer and TTS, addressing unmet needs and practical implications. The importance of a close collaboration between cardiologists and oncologists is herein highlighted, both to allow an adequate management of the acute TTS phase, and to actively and safely return to the oncologic management once the acute setting is resolved.

Scoping Review of Measures of Comorbidities in Heart Failure

BACKGROUND

Comorbidities are risk factors for poor clinical outcomes in patients with heart failure. However, no consensus has been reached on how to assess comorbidities related to clinical outcomes in patients with heart failure.

OBJECTIVE

The aims of this study were to review (1) how comorbidities have been assessed, (2) what chronic conditions have been identified as comorbidities and (3) the rationale for choosing the comorbidity instruments and/or specific comorbidities when exploring clinical outcomes in patients with heart failure.

METHODS

The clinical outcomes of interest were mortality, hospitalization, quality of life, and self-care. Three electronic databases and reference list searches were used in the search.

RESULTS

In this review, we included 39 articles using 3 different ways to assess comorbidities in the relationship with clinical outcomes: using an instrument (ie, Charlson Comorbidity Index), disease count, and including individual comorbidities. A total of 90 comorbidities were investigated in the 39 articles; however, definitions and labels for the diseases were inconsistent across the studies. More than half of the studies (n = 22) did not provide a rationale for selecting the comorbidity instruments and/or all of the specific comorbidities. Some of the rationale for choosing the instruments and/or specific comorbidities was inappropriate.

CONCLUSIONS

We found several issues related to measuring comorbidities when examining clinical outcomes in patients with heart failure. Researchers need to consider these methodological issues when measuring comorbidities in patients with heart failure. Further efforts are needed to develop guidelines on how to choose proper measures for comorbidities.

Effect of Admission and Onset Time on the Prognosis of Patients With Cardiogenic Shock

BACKGROUND

The spectrum of patients with cardiogenic shock (CS) has changed significantly over time. CS has become especially more common in the absence of acute myocardial infarction (AMI), while this subset of patients was typically excluded from recent studies. Furthermore the prognostic impact of onset time and onset place due to CS has rarely been investigated.

RESEARCH QUESTION

Do the place of CS onset (out-of-hospital, ie, primary CS vs in-hospital, ie, secondary CS) and the onset time of out-of-hospital CS (ie, on-hours vs off-hours admission) affect the risk of all-cause mortality at 30 days?

STUDY DESIGN AND METHODS

This prospective monocentric registry included consecutive patients with CS of any cause from 2019 until 2021. First, the prognostic impact of the place of CS onset (out-of-hospital, ie, primary CS vs during hospitalization, ie, secondary CS) was investigated. Thereafter, the prognostic impact of the onset time of out-of-hospital CS was investigated. Furthermore, the prognostic impact of causative AMI vs non-AMI was investigated. Statistical analyses included Kaplan-Meier analyses, and univariable and multivariable Cox regression analyses.

RESULTS

Two hundred seventy-three patients with CS were included prospectively (64% with primary out-of-hospital CS). The place of CS onset was not associated with increased risk of all-cause mortality within the entire study cohort (secondary in-hospital CS: hazard ratio [HR], 1.532; 95% CI, 0.990-2.371; P = .06). However, increased risk of 30-day all-cause mortality was seen in patients with AMI related secondary in-hospital CS (HR, 2.087; 95% CI, 1.126-3.868; P = .02). Furthermore, primary out-of-hospital CS admitted during off-hours was associated with lower risk of all-cause mortality compared to primary CS admitted during on-hours (HR, 0.497; 95% CI, 0.302-0.817; P = .01), irrespective of the presence or absence of AMI.

INTERPRETATION

Primary and secondary CS were associated with comparable, whereas primary out-of-hospital CS admitted during off-hours was associated with lower risk of all-cause mortality at 30 days.

The Interplay of Comorbidities in Chronic Heart Failure: Challenges and Solutions

BACKGROUND

Chronic heart failure (HF) is frequently associated with various comorbidities. These comorbid conditions, such as anemia, diabetes mellitus, renal insufficiency, and sleep apnea, can significantly impact the prognosis of patients with HF.

OBJECTIVE

This review aims to synthesize current evidence on the prevalence, impact, and management of comorbidities in patients with chronic HF.

METHODS

A comprehensive review was conducted, with a rigorous selection process. Out of an initial pool of 59,030 articles identified across various research modalities, 134 articles were chosen for inclusion. The selection spanned various research methods, from randomized controlled trials to observational studies.

RESULTS

Comorbidities are highly prevalent in patients with HF and contribute to increased hospitalization rates and mortality. Despite advances in therapies for HF with reduced ejection fraction, options for treating HF with preserved ejection fraction remain sparse. Existing treatment protocols often lack standardization, reflecting a limited understanding of the intricate relationships between HF and associated comorbidities.

CONCLUSION

There is a pressing need for a multidisciplinary, tailored approach to manage HF and its intricate comorbidities. This review underscores the importance of ongoing research efforts to devise targeted treatment strategies for HF patients with various comorbid conditions.

The importance of patient characteristics, operators, and image quality for the accuracy of heart failure diagnosis by general practitioners using handheld ultrasound devices

Aims

To evaluate whether the characteristics of patients, operators, and image quality could explain the accuracy of heart failure (HF) diagnostics by general practitioners (GPs) using handheld ultrasound devices (HUDs) with automatic decision-support software and telemedical support.

Methods and results

Patients referred to an outpatient cardiac clinic due to symptoms indicating HF were examined by one of five GPs after dedicated training. In total, 166 patients were included [median (inter-quartile range) age 73 (63-78) years; mean ± standard deviation ejection fraction 53 ± 10%]. The GPs considered whether the patients had HF in four diagnostic steps: (i) clinical examination, (ii) adding focused cardiac HUD examination, (iii) adding automatic decision-support software measuring mitral annular plane systolic excursion (autoMAPSE) and ejection fraction (autoEF), and (iv) adding telemedical support. Overall, the characteristics of patients, operators, and image quality explained little of the diagnostic accuracy. Except for atrial fibrillation [lower accuracy for HUD alone and after adding autoEF (P < 0.05)], no patient characteristics influenced the accuracy. Some differences between operators were found after adding autoMAPSE (P < 0.05). Acquisition errors of the four-chamber view and a poor visualization of the mitral plane were associated with reduced accuracy after telemedical support (P < 0.05).

Conclusion

The characteristics of patients, operators, and image quality explained just minor parts of the modest accuracy of GPs' HF diagnostics using HUDs with and without decision-support software. Atrial fibrillation and not well-standardized recordings challenged the diagnostic accuracy. However, the accuracy was only modest in well-recorded images, indicating a need for refinement of the technology.

Multimorbidity in patients with acute heart failure across world regions and country income levels (REPORT-HF): a prospective, multicentre, global cohort study

BACKGROUND

Multimorbidity (two or more comorbidities) is common among patients with acute heart failure, but comprehensive global information on its prevalence and clinical consequences across different world regions and income levels is scarce. This study aimed to investigate the prevalence of multimorbidity and its effect on pharmacotherapy and prognosis in participants of the REPORT-HF study.

METHODS

REPORT-HF was a prospective, multicentre, global cohort study that enrolled adults (aged ≥18 years) admitted to hospital with a primary diagnosis of acute heart failure from 358 hospitals in 44 countries on six continents. Patients who currently or recently participated in a clinical treatment trial were excluded. Follow-up data were collected at 1-year post-discharge. The primary outcome was 1-year post-discharge mortality. All patients in the REPORT-HF cohort with full data on comorbidities were eligible for the present study. We stratified patients according to the number of comorbidities, and countries by world region and country income level. We used one-way ANOVA, χ2 test, or Mann-Whitney U test for comparisons between groups, as applicable, and Cox regression to analyse the association between multimorbidity and 1-year mortality.

FINDINGS

Between July 23, 2014, and March 24, 2017, 18 553 patients were included in the REPORT-HF study. Of these, 18 528 patients had full data on comorbidities, of whom 11 360 (61%) were men and 7168 (39%) were women. Prevalence rates of multimorbidity were lowest in southeast Asia (72%) and highest in North America (92%). Fewer patients from lower-middle-income countries had multimorbidity than patients from high-income countries (73% vs 85%, p<0·0001). With increasing comorbidity burden, patients received fewer guideline-directed heart failure medications, yet more drugs potentially causing or worsening heart failure. Having more comorbidities was associated with worse outcomes: 1-year mortality increased from 13% (no comorbidities) to 26% (five or more comorbidities). This finding was independent of common baseline risk factors, including age and sex. The population-attributable fraction of multimorbidity for mortality was higher in high-income countries than in upper-middle-income or lower-middle-income countries (for patients with five or more comorbidities: 61% vs 27% and 31%, respectively).

INTERPRETATION

Multimorbidity is highly prevalent among patients with acute heart failure across world regions, especially in high-income countries, and is associated with higher mortality, less prescription of guideline-directed heart failure pharmacotherapy, and increased use of potentially harmful medications.

Epidemiology, Clinical Characteristics and Cause-specific Outcomes in Heart Failure with Preserved Ejection Fraction

Heart failure (HF) is a global pandemic affecting 64 million people worldwide. HF with preserved ejection fraction (HFpEF) has traditionally received less attention than its main counterpart, HF with reduced ejection fraction (HFrEF). The incidence and prevalence of HFpEF show geographic variation and are increasing over time, soon expected to surpass those of HFrEF. Morbidity and mortality rates of HFpEF are considerable, albeit lower than those of HFrEF. This review focuses on the burden of HFpEF, providing contemporary data on epidemiology, clinical characteristics and comorbidities, cause-specific outcomes, costs and pharmacotherapy.

Multimorbidity in Heart Failure: Leveraging Cluster Analysis to Guide Tailored Treatment Strategies

REVIEW PURPOSE

This review summarises key findings on treatment effects within phenotypical clusters of patients with heart failure (HF), making a distinction between patients with preserved ejection fraction (HFpEF) and reduced ejection fraction (HFrEF).

FINDINGS

Treatment response differed among clusters; ACE inhibitors were beneficial in all HFrEF phenotypes, while only some studies show similar beneficial prognostic effects in HFpEF patients. Beta-blockers had favourable effects in all HFrEF patients but not in HFpEF phenotypes and tended to worsen prognosis in older, cardiorenal patients. Mineralocorticoid receptor antagonists had more favourable prognostic effects in young, obese males and metabolic HFpEF patients. While a phenotype-guided approach is a promising solution for individualised treatment strategies, there are several aspects that still require improvements before such an approach could be implemented in clinical practice. Stronger evidence from clinical trials and real-world data may assist in establishing a phenotype-guided treatment approach for patient with HF in the future.

Impact of a heart failure multidisciplinary clinic on the reduction of healthcare-related events and costs: the GEstIC study

Introduction

Heart failure (HF) is the leading cause of hospitalization in the elderly in developed countries and significantly impacts public health expenditures. Patients with HF usually have associated comorbidities that require multidisciplinary management. This study aims to demonstrate the benefits of a multidisciplinary clinic in reducing all-cause hospitalizations and HF events (HF hospitalizations and urgent HF visits) in a real-world setting. Finally, the study evaluates the associated costs of HF events.

Methods

This observational study included patients admitted to GEstIC, a multidisciplinary Portuguese HF clinic, from January 2013 to February 2019, who had one-year follow-up. Hospitalizations and HF events, total days spent in the hospital during HF hospitalizations, and HF events-related costs, in the year before and the year after GEstIC admission, were compared.

Results

Of the 487 patients admitted to the GEstIC, 287 were eligible for the study sample. After one year of HF patients' multidisciplinary management at GEstIC, there was a 53.7% reduction in all-cause hospitalizations (462 vs. 214), a 71.7% reduction in HF hospitalizations (392 vs. 111), and a 39.1% reduction in urgent HF visits (87 vs. 53). As a result, there was a significant decrease of 12.6 days in the length of hospital stay due to HF per patient (15.6 vs. 3.0, p < 0.001). This translated into the release of 9.9 hospital beds in the year following admission to GEstIC. The average total savings associated with the reduction of HF events was €5,439.77 per patient (6,774.15 vs. 1,334.38, p < 0.001), representing a total cost reduction of €1,561,213. Furthermore, the significant reduction in the number of all events was independent of the patient's left ventricular ejection fraction (LVEF).

Discussion

Significant reductions in all-cause and HF hospitalizations and urgent HF visits were observed with the implementation of this multidisciplinary clinic for HF patients' management. This was particularly important for patients with LVEF >40%. Before GEstIC, there was no medical intervention to improve the prognosis of these patients. The reduction of over one million euros in health-related costs after only one year of person-centered multidisciplinary management highlights the need to replicate this approach in other national healthcare institutions.

Impact of comorbidities on health status measured using the Kansas City Cardiomyopathy Questionnaire in patients with heart failure with reduced and preserved ejection fraction

AIM

Patients with heart failure (HF) often suffer from a range of comorbidities, which may affect their health status. The aim of this study was to assess the impact of different comorbidities on health status in patients with HF and reduced (HFrEF) and preserved ejection fraction (HFpEF).

METHODS AND RESULTS

Using individual patient data from HFrEF (ATMOSPHERE, PARADIGM-HF, DAPA-HF) and HFpEF (TOPCAT, PARAGON-HF) trials, we examined the Kansas City Cardiomyopathy Questionnaire (KCCQ) domain scores and overall summary score (KCCQ-OSS) across a range of cardiorespiratory (angina, atrial fibrillation [AF], stroke, chronic obstructive pulmonary disease [COPD]) and other comorbidities (obesity, diabetes, chronic kidney disease [CKD], anaemia). Of patients with HFrEF (n = 20 159), 36.2% had AF, 33.9% CKD, 33.9% diabetes, 31.4% obesity, 25.5% angina, 12.2% COPD, 8.4% stroke, and 4.4% anaemia; the corresponding proportions in HFpEF (n = 6563) were: 54.0% AF, 48.7% CKD, 43.4% diabetes, 53.3% obesity, 28.6% angina, 14.7% COPD, 10.2% stroke, and 6.5% anaemia. HFpEF patients had lower KCCQ domain scores and KCCQ-OSS (67.8 vs. 71.3) than HFrEF patients. Physical limitations, social limitations and quality of life domains were reduced more than symptom frequency and symptom burden domains. In both HFrEF and HFpEF, COPD, angina, anaemia, and obesity were associated with the lowest scores. An increasing number of comorbidities was associated with decreasing scores (e.g. KCCQ-OSS 0 vs. ≥4 comorbidities: HFrEF 76.8 vs. 66.4; HFpEF 73.7 vs. 65.2).

CONCLUSIONS

Cardiac and non-cardiac comorbidities are common in both HFrEF and HFpEF patients and most are associated with reductions in health status although the impact varied among comorbidities, by the number of comorbidities, and by HF phenotype. Treating/correcting comorbidity is a therapeutic approach that may improve the health status of patients with HF.

Guideline-based audit of the hospital management of heart failure with reduced ejection fraction

BACKGROUND

Heart failure is a major burden in Australia in terms of morbidity, mortality and healthcare expenditure. Multiple evidence-based therapies are recommended for heart failure with reduced ejection fraction (HFrEF), but data on physician adherence to therapy guidelines are limited.

AIM

To compare use of HFrEF therapies against current evidence-based guidelines in an Australian hospital inpatient population.

METHODS

A retrospective review of patients admitted with a principal diagnosis of HFrEF across six metropolitan hospitals in Sydney, Australia, between January 2015 and June 2016. Use of medical and device therapies was compared with guideline recommendations using individual patient indications/contraindications. Readmission and mortality data were collected for a 1-year period following the admission.

RESULTS

Of the 1028 HFrEF patients identified, 39 were being managed with palliative intent, leaving 989 patients for the primary analysis. Use of beta-blockers (87.7% actual use/93.6% recommended use) and diuretics (88.4%/99.3%) was high among eligible patients. There were large evidence-practice gaps for angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (ACEI/ARB; 66.4%/89.0%) and aldosterone antagonists (41.0%/77.1%). In absolute terms, use of these therapies each increased by over 11% from admission. Ivabradine (11.5%/21.2%), automated internal cardiac defibrillators (29.5%/66.1%) and cardiac resynchronisation therapy (13.1%/28.7%) were used in a minority of eligible patients. Over the 1-year follow-up period, the mortality rate was 14.8%, and 44.2% of patients were readmitted to hospital at least once.

CONCLUSION

Hospitalisation is a key mechanism for initiation of HFrEF therapies. The large evidence-practice gaps for ACEI/ARB and aldosterone antagonists represent potential avenues for improved HFrEF management.

Acute Antipsychotic Use and Presence of Dysphagia Among Older Veterans with Heart Failure

OBJECTIVE

Examine whether new antipsychotic (AP) exposure is associated with dysphagia in hospitalized patients with heart failure (HF).

DESIGN

Retrospective cohort.

SETTINGS AND PARTICIPANTS

AP-naïve Veterans hospitalized with HF and subsequently discharged to a skilled nursing facility (SNF) between October 1, 2010, and November 30, 2019.

METHODS

We linked Veterans Health Administration (VHA) electronic medical records with Centers for Medicare & Medicaid (CMS) Minimum Data Set (MDS) version 3.0 assessments and CMS claims. The exposure variable was administration of ≥1 dose of a typical or atypical AP during hospitalization. Our main outcome measure was dysphagia presence defined by (1) inpatient dysphagia diagnosis codes and (2) the SNF admission MDS 3.0 swallowing-related items to examine post-acute care dysphagia status. Inverse probability of treatment weighting was used for risk adjustment.

RESULTS

The analytic cohort consisted of 29,591 Veterans (mean age 78.5 ± 10.0 years; female 2.9%; n = 865). Acute APs were administered to 9.9% (n = 2941). Those receiving APs had differences in prior dementia [37.1%, n = 1091, vs 22.3%, n = 5942; standardized mean difference (SMD) = 0.33] and hospital delirium diagnoses (7.7%, n = 227 vs 2.8%, n = 754; SMD = 0.22). Acute AP exposure was associated with nearly double the risk for hospital dysphagia diagnosis codes [adjusted (adj.) relative risk (RR) 1.9, 95% CI 1.8, 2.1]. At the SNF admission MDS assessment, acute AP administration during hospitalization was associated with an increased dysphagia risk (adj. RR 1.2, 95% CI 1.0, 1.5) both in the oral (adj. RR 1.7, 95% CI 1.2, 2.0) and pharyngeal phases (adj. RR 1.3, 95% CI 1.0, 1.7).

CONCLUSIONS AND IMPLICATIONS

In this retrospective study, AP medication exposure was associated with increased dysphagia coding and MDS assessment. Considering other adverse effects, acute AP should be cautiously administered during hospitalization, particularly in those with dementia. Swallowing function is critical to hydration, nutrition, and medical management of HF; therefore, when acute APs are initiated, a swallow evaluation should be considered.

Predictors of patient self-advocacy among patients with chronic heart failure

The purpose of this study was to examine predictors of self-advocacy among patients with chronic heart failure (HF) as they were unknown. A convenience sample of 80 participants recruited from one Midwestern HF clinic completed surveys related to relationship-based predictors of patient self-advocacy including trust in nurses and social support. Self-advocacy is operationalized using the three dimensions of HF knowledge, assertiveness, and intentional non-adherence. Hierarchical multiple regression was used showing that trust in nurses predicted HF knowledge (ΔR² = 0.070, F = 5.91, p < .05), social support predicted advocacy assertiveness (ΔR² = 0.068, F = 5.67, p < .05), and ethnicity predicted overall self-advocacy (ΔR² = 0.059, F = 4.89, p < .05). These findings suggest that support from family and friends can give the patient the needed encouragement to advocate for what they need. A trusting relationship with nurses impacts patient education so that patients not only understand their illness and its trajectory but also use that understanding to speak up for themselves. African American patients, who are less likely to self-advocate than their White counterparts, could benefit from nurses recognizing the impact of implicit bias so that these patients do not feel silenced in their care.

Heart Failure Prevalence Rates and Its Association with Other Cardiovascular Diseases and Chronic Kidney Disease: SIMETAP-HF Study

INTRODUCTION AND OBJECTIVES

Heart failure (HF) is a major health problem that causes high mortality and hospitalization rates. This study aims to determine the HF prevalence rates in populations aged both ≥18 years and ≥50 years and to assess its association with cardiovascular diseases and chronic kidney disease.

METHODS

A cross-sectional observational study was conducted in a primary care setting, with a population-based random sample of 6588 people aged 18.0-102.8 years. Crude and adjusted prevalence rates of HF were calculated. The associations of renal and cardiometabolic factors with HF were assessed in both populations using univariate, bivariate and multivariate analysis.

RESULTS

The HF crude prevalence rates were 2.8% (95%CI: 2.4-3.2) in adults (≥18 years), and 4.6% (95%CI: 4.0-5.3) in the population aged ≥ 50 years, without significant differences between males and females in both populations. The age- and sex-adjusted prevalence rates were 2.1% (male: 1.9%; female: 2.3%) in the overall adult population, and 4.5% (male: 4.2%; female: 4.8%) in the population aged ≥ 50 years, reaching 10.0% in the population aged ≥ 70 years. Atrial fibrillation, hypertension, low estimated glomerular filtration rate (eGFR), coronary heart disease (CHD), stroke, sedentary lifestyle, and diabetes were independently associated with HF in both populations. A total of 95.7% (95%CI: 92.7-98.6) of the population with HF had an elevated cardiovascular risk.

CONCLUSIONS

This study reports that HF prevalence increases from 4.5% in the population over 50 years to 10% in the population over 70 years. The main clinical conditions that are HF-related are sedentary lifestyle, atrial fibrillation, hypertension, diabetes, low eGFR, stroke, and CHD.

The influence of comorbidities on the prognosis after an acute heart failure decompensation and differences according to ejection fraction: Results from the EAHFE and RICA registries

OBJECTIVE

The role of comorbidities in heart failure (HF) outcome has been previously investigated, although mostly individually. We investigated the individual effect of 13 comorbidities on HF prognosis and looked for differences according to left-ventricular ejection fraction (LVEF), classified as reduced (HFrEF), mildly-reduced (HFmrEF) and preserved (HFpEF).

METHODS

We included patients from the EAHFE and RICA registries and analysed the following comorbidities: hypertension, dyslipidaemia, diabetes mellitus (DM), atrial fibrillation (AF), coronary artery disease (CAD), chronic kidney disease (CKD), chronic obstructive pulmonary disease (COPD), heart valve disease (HVD), cerebrovascular disease (CVD), neoplasia, peripheral artery disease (PAD), dementia and liver cirrhosis (LC). Association of each comorbidity with all-cause mortality was assessed by an adjusted Cox regression analysis that included the 13 comorbidities, age, sex, Barthel index, New York Heart Association functional class and LVEF and expressed as adjusted Hazard Ratios (HR) with 95% confidence intervals (95%CI).

RESULTS

We analysed 8,336 patients (82 years-old; 53% women; 66% with HFpEF). Mean follow-up was 1.0 years. Respect to HFrEF, mortality was lower in HFmrEF (HR:0.74;0.64-0.86) and HFpEF (HR:0.75;0.68-0.84). Considering patients all together, eight comorbidities were associated with mortality: LC (HR:1.85;1.42-2.42), HVD (HR:1.63;1.48-1.80), CKD (HR:1.39;1.28-1.52), PAD (HR:1.37;1.21-1.54), neoplasia (HR:1.29;1.15-1.44), DM (HR:1.26;1.15-1.37), dementia (HR:1.17;1.01-1.36) and COPD (HR:1.17;1.06-1.29). Associations were similar in the three LVEF subgroups, with LC, HVD, CKD and DM remaining significant in the three subgroups.

CONCLUSION

HF comorbidities are associated differently with mortality, LC being the most associated with mortality. For some comorbidities, this association can be significantly different according to the LVEF.

The Prevalence of Depression and Anxiety in Heart Failure Patients in Saudi Arabia: An Original Study

Background Depression is a severe comorbidity that is often detected in patients with chronic diseases. Poor prognosis may eventuate high mortality risk. Up to 30% of heart failure patients have been documented with depression and the majority upholds depression-related symptoms that may have serious clinical implications, such as hospital readmissions and fatalities. To mitigate depression-induced harms among heart failure patients, studies are being conducted to determine the prevalence, risk factors, and interventions. Objectives The current investigation is envisioned to examine the prevalence of depression and anxiety among the Saudi heart failure population. Also, it will help to explore the risk factors that will subsequently facilitate the analysis of preventive measures. Methodology The cross-sectional epidemiologic research was conducted at King Khalid University, Hospital with the recruitment of 205 participants. Each participant underwent a 30-question screening for depression, anxiety, and related risk factors. The "Hospital, Anxiety, and Depression Scale" (HADS score) was used to score subjects for the assessment of both comorbidities. The data points were subsequently analyzed by descriptive statistics and regression analysis. Results Among 205 participants, 137 (66.82%) were male and 68 (33.17%) were female with a mean age of 59.71 years. Our sample reflects a prevalence of 52.7% depression and 56.9% anxiety in Saudi heart failure patients. High depression scores were positively related to age, female gender, hospital readmissions, and pre-existing comorbidities in heart failure patients. Conclusion The study manifested high depression scores among the Saudi heart failure cohort compared to the previous survey. In addition, a substantial interrelationship of depression and categorical variables has been identified that accentuates predominating risks that can potentially promote depression and anxiety in heart failure patients.

Acute Cardiorenal Syndrome: An Update

The complex dynamic pathophysiological interplay between the heart and kidney causes a vicious cycle of worsening renal and/or cardiovascular function. Acute decompensated heart failure causing worsening renal function defines Type 1 cardiorenal syndrome (CRS). Altered hemodynamics coupled with a multitude of nonhemodynamic factors namely pathological activation of the renin angiotensin aldosterone system and systemic inflammatory pathways mechanistically incite CRS type 1. A multipronged diagnostic approach utilizing laboratory markers, noninvasive and/or invasive modalities must be implemented to enable timely initiation of effective treatment strategies. In this review, we discuss the pathophysiology, diagnosis, and emerging treatment options for CRS type 1.

Charlson Comorbidity Index is correlated with all-cause readmission within six months in patients with heart failure: a retrospective cohort study in China

BACKGROUND

Charlson Comorbidity Index (CCI) is positively associated with all-cause readmission in patients with heart failure (HF) in western countries. However, there is a scarcity of strong scientific evidence supporting the correlation in China. This study aimed at testing this hypothesis in Chinese.   METHODS: We conducted a secondary analysis of 1,946 patients with HF in Zigong Fourth People's Hospital in China between December 2016 to June 2019. Logistic regression models were used to study the hypotheses, with adjustments for the four regression models. We also explore the linear trend and possible nonlinear relationship between CCI and readmission within six months. We further conducted subgroup analysis and tests for interaction to examine the possible interaction between CCI and the endpoint. Additionally, CCI alone and several combinations of variables based on CCI were used to predict the endpoint. Under the curve (AUC), sensitivity and specificity were reported to evaluate the performance of the predicted model.

RESULTS

In the adjusted II model, CCI was an independent prognostic factor for readmission within six months in patients with HF (OR = 1.14, 95% CI: 1.03-1.26, P = 0.011). Trend tests revealed that there was a significant linear trend for the association. A nonlinear association was identified between them and the inflection point of CCI was 1. Subgroup analyses and tests for interaction indicated that cystatin played an interactive role in the association. ROC analysis indicated neither CCI alone nor combinations of variables based on CCI were adequate for prediction.

CONCLUSION

CCI was independently positively correlated with readmission within six months in patients with HF in Chinese population. However, CCI has limited value on predicting readmission within six months in patients with HF.

Comorbidities complicating heart failure: changes over the last 15 years

AIMS

Management of comorbidities represents a critical step in optimal treatment of heart failure (HF) patients. However, minimal attention has been paid whether comorbidity burden and their prognostic value changes over time. Therefore, we examined the association between comorbidities and clinical outcomes in HF patients between 2002 and 2017.

METHODS AND RESULTS

The 2002-HF cohort consisted of patients from The Coordinating Study Evaluating Outcomes of Advising and Counseling in Heart Failure (COACH) trial (n = 1,032). The 2017-HF cohort were outpatient HF patients enrolled after hospitalization for HF in a tertiary referral academic hospital (n = 382). Kaplan meier and cox regression analyses were used to assess the association of comorbidities with HF hospitalization and all-cause mortality. Patients from the 2017-cohort were more likely to be classified as HF with preserved ejection fraction (24 vs 15%, p < 0.001), compared to patients from the 2002-cohort. Comorbidity burden was comparable between both cohorts (mean of 3.9 comorbidities per patient) and substantially increased with age. Higher comorbidity burden was significantly associated with a comparable increased risk for HF hospitalization and all-cause mortality (HR 1.12 [1.02-1.22] and HR 1.18 [1.05-1.32]), in the 2002- and 2017-cohort respectively. When assessing individual comorbidities, obesity yielded a statistically higher prognostic effect on outcome in the 2017-cohort compared to the 2002-HF cohort (p for interaction 0.026).

CONCLUSION

Despite major advances in HF treatment over the past decades, comorbidity burden remains high in HF and influences outcome to a large extent. Obesity emerges as a prominent comorbidity, and efforts should be made for prevention and treatment. Created with BioRender.com.

Effects of a multidisciplinary management program on symptom burden and medication adherence in heart failure patients with comorbidities: A randomized controlled trial

BACKGROUND

Comorbidities in heart failure (HF) are a complex clinical challenge. There is little data on the benefits of multidisciplinary postdischarge management programs in such patients. This study aimed to examine the effects of a multidisciplinary management program (MMP) on symptom burden and medication adherence in HF patients with comorbidities.

METHODS

In this clinical trial study, 94 HF patients with comorbidities were assigned to intervention (n = 47) and control (n = 47) groups by the stratified-random method. The intervention group underwent MMP supervised by a nurse for two months after discharge, including multi-professional visits, telephone follow-ups, and an educational booklet. Medication adherence and symptom burden were assessed using Morisky Medication Adherence Scale (MMAS) and Edmonton Symptom Assessment Scale (ESAS), respectively, on three occasions: Before discharge, six weeks, and eight weeks after discharge.

RESULTS

Both groups almost matched at the baseline, and the most frequent comorbidities included myocardial infarction (MI), hypertension, peptic ulcer, and depression, respectively. The interactive effect of time in groups showed that mean changes in total scores of symptom burden and medication adherence were significantly different (P < 0.001) at other time points. A significant increase in medication adherence (P < 0.001) and a significant reduction in the burden of all symptoms were observed in the intervention group compared to the control group from Time 1 to Time 3.

CONCLUSIONS

The MMP (targeting comorbidity) is a promising strategy for managing symptoms and medication adherence in HF patients with comorbidities.

Heart failure: an update from the last years and a look at the near future

In the last years, major progress occurred in heart failure (HF) management. Quadruple therapy is now mandatory for all the patients with HF with reduced ejection fraction. Whilst verciguat is becoming available across several countries, omecamtiv mecarbil is waiting to be released for clinical use. Concurrent use of potassium-lowering agents may counteract hyperkalaemia and facilitate renin-angiotensin-aldosterone system inhibitor implementations. The results of the EMPagliflozin outcomE tRial in Patients With chrOnic heaRt Failure With Preserved Ejection Fraction (EMPEROR-Preserved) trial were confirmed by the Dapagliflozin in Heart Failure with Mildly Reduced or Preserved Ejection Fraction (DELIVER) trial, and we now have, for the first time, evidence for treatment of also patients with HF with preserved ejection fraction. In a pre-specified meta-analysis of major randomized controlled trials, sodium-glucose co-transporter-2 inhibitors reduced all-cause mortality, cardiovascular (CV) mortality, and HF hospitalization in the patients with HF regardless of left ventricular ejection fraction. Other steps forward have occurred in the treatment of decompensated HF. Acetazolamide in Acute Decompensated Heart Failure with Volume Overload (ADVOR) trial showed that the addition of intravenous acetazolamide to loop diuretics leads to greater decongestion vs. placebo. The addition of hydrochlorothiazide to loop diuretics was evaluated in the CLOROTIC trial. Torasemide did not change outcomes, compared with furosemide, in TRANSFORM-HF. Ferric derisomaltose had an effect on the primary outcome of CV mortality or HF rehospitalizations in IRONMAN (rate ratio 0.82; 95% confidence interval 0.66-1.02; P = 0.070). Further options for the treatment of HF, including device therapies, cardiac contractility modulation, and percutaneous treatment of valvulopathies, are summarized in this article.

Geriatric Domains in Patients with Heart Failure with Preserved Ejection Fraction

Because heart failure with preserved ejection fraction (HFpEF) is closely linked to aging processes and disproportionately affects older adults, consideration of geriatric domains is paramount to ensure high-quality care to older adults with HFpEF. Multimorbidity, polypharmacy, cognitive impairment, depressive symptoms, frailty, falls, and social isolation each have important implications on quality of life and clinical events including hospitalization and mortality. There are multiple strategies to screen for these conditions. This narrative review underscores the importance of screening for multiple geriatric conditions, integrating these conditions into decision making, and addressing these conditions when caring for older adults with HFpEF.

AI-Supported Comprehensive Detection and Quantification of Biomarkers of Subclinical Widespread Diseases at Chest CT for Preventive Medicine

Automated image analysis plays an increasing role in radiology in detecting and quantifying image features outside of the perception of human eyes. Common AI-based approaches address a single medical problem, although patients often present with multiple interacting, frequently subclinical medical conditions. A holistic imaging diagnostics tool based on artificial intelligence (AI) has the potential of providing an overview of multi-system comorbidities within a single workflow. An interdisciplinary, multicentric team of medical experts and computer scientists designed a pipeline, comprising AI-based tools for the automated detection, quantification and characterization of the most common pulmonary, metabolic, cardiovascular and musculoskeletal comorbidities in chest computed tomography (CT). To provide a comprehensive evaluation of each patient, a multidimensional workflow was established with algorithms operating synchronously on a decentralized Joined Imaging Platform (JIP). The results of each patient are transferred to a dedicated database and summarized as a structured report with reference to available reference values and annotated sample images of detected pathologies. Hence, this tool allows for the comprehensive, large-scale analysis of imaging-biomarkers of comorbidities in chest CT, first in science and then in clinical routine. Moreover, this tool accommodates the quantitative analysis and classification of each pathology, providing integral diagnostic and prognostic value, and subsequently leading to improved preventive patient care and further possibilities for future studies.

Outcomes of Octogenarians with Primary Malignant Cardiac Tumors: National Cancer Database Analysis

Data concerning age-related populations affected with primary malignant cardiac tumors (PMCTs) are still scarce. The aim of the current study was to analyze mortality differences amongst different age groups of patients with PMCTs, as reported by the National Cancer Database (NCDB). The NCDB was retrospectively reviewed for PMCTs from 2004 to 2017. The primary outcome was late mortality differences amongst different age categories (octogenarian, septuagenarian, younger age), while secondary outcomes included differences in treatment patterns and perioperative (30-day) mortality. A total of 736 patients were included, including 72 (9.8%) septuagenarians and 44 (5.98%) octogenarians. Angiosarcoma was the most prevalent PMCT. Surgery was performed in 432 (58.7%) patients (60.3%, 55.6%, and 40.9% in younger age, septuagenarian, and octogenarian, respectively, p = 0.04), with a corresponding 30-day mortality of 9.0% (7.0, 15.0, and 38.9% respectively, p < 0.001) and a median overall survival of 15.7 months (18.1, 8.7, and 4.5 months respectively). Using multivariable Cox regression, independent predictors of late mortality included octogenarian, governmental insurance, CDCC grade II/III, earlier year of diagnosis, angiosarcoma, stage III/IV, and absence of surgery/chemotherapy. With increasing age, patients presented a more significant comorbidity burden compared to younger ones and were treated more conservatively. Early and late survival outcomes progressively declined with advanced age.

Use of potentially inappropriate medications for heart failure according to the three sets of heart failure-specific criteria in Thai older patients with heart failure

OBJECTIVE

To study the prevalence of potentially inappropriate medications for patients with heart failure (PIMHF) use and to identify factors associated with PIMHF use in Thai older HF patients.

METHODS

This cross-sectional analytical survey included data on older (≥ 60 years) HF patients obtained from the electronic medical record databases of secondary- and tertiary-care hospitals. The medication profiles of patients were assessed to examine whether they were prescribed any PIMHF after an HF diagnosis. For PIMHF detection, the HF-specific criteria, including 2014 St Vincent criteria, 2019 Beers criteria, and 2021 Thailand criteria were applied. The prevalence of PIMHF use was expressed as percentages. The associated factors were identified using a binary logistic regression analysis, expressed as the adjusted odds ratio (aOR) and 95% confidence interval (95% CI).

RESULTS

A total of 2,639 patients were included in the study. Thirty-two PIMHF were found to have been prescribed to these patients. The prevalence of PIMHF use identified by the ST Vincent criteria, the Beers criteria, the Thailand criteria, and the three combined criteria was 23.76%, 19.67%, 21.18%, and 25.16%, respectively. The factors associated with PIMHF use were secondary-care hospital (aOR = 1.54, 95% CI: 1.26-1.87), HF with preserved ejection fraction (HFpEF) (aOR = 1.81, 95% CI: 1.38-2.38), hypertension (HTN) (aOR = 1.24, 95% CI: 1.02-1.51), diabetes mellitus (DM) (aOR = 1.39, 95% CI: 1.10-1.75), chronic pulmonary diseases (CPD) (aOR = 2.09, 95% CI: 1.56-2.80), and connective tissue diseases (CTD) (aOR = 5.10, 95% CI: 2.20-11.83).

CONCLUSIONS

PIMHF are commonly used in Thai older HF patients. The factors associated with PIMHF use identified in this study include secondary-care hospital, HFpEF, HTN, DM, CPD, and CTD.

Increased Mortality Trends in Patients With Chronic Non-communicable Diseases and Comorbid Hypertension in the United States, 2000–2019

Background

According to the Sustainable Development Goals (SDGs), countries are required to reduce the mortality rates of four main non-communicable diseases (NCDs), including cardiovascular diseases (CVDs), diabetes mellitus (DM), chronic respiratory diseases (CRDs), and cancer (CA), by one-third in 2030 from the 2015 level. However, progress fell short of expectations, partly attributed to the high rates of hypertension-related NCD mortality. This study aimed to investigate the mortality trends of SDG-targeted NCDs with comorbid hypertension. In addition, the disparities in mortality rates among different demographic subgroups were further explored.

Methods

Mortality data from 2000 to 2019 were acquired from the Centers for Disease Control and Prevention in the United States. SDG-targeted NCDs were considered the underlying causes of death, and hypertension was considered a multiple cause of death. Permutation tests were performed to determine the time points of Joinpoints for mortality trends. The annual percent changes and average annual percent changes (AAPCs), as well as 95% confidence intervals (CIs), were calculated to demonstrate the temporary trend of mortality rates overall and by age, sex, ethnicity, and region.

Results

The hypertension-related DM, CRD, and CA mortality rates increased over the 20 years, of which the AAPCs were 2.0% (95% CI: 1.4%, 2.6%), 3.2% (95% CI: 2.8%, 3.6%), and 2.1% (95% CI: 1.6%, 2.6%), respectively. Moreover, despite decreasing between 2005 and 2015, the hypertension-related CVD mortality rate increased from 2015 to 2019 [APC: 1.3% (95% CI: 0.7%, 1.9%)]. The increased trends were consistent across most age groups. Mortality rates among men were higher and increased faster than those among women. The hypertension-related CVD, DM, and CA mortality rates among African American people were higher than those among White people. The increased mortality rates in rural areas, especially in rural south, were higher than those in urban areas.

Conclusion

In the United States, the hypertension-related DM, CRD, and CA mortality rates increased between 2000 and 2019, as well as hypertension-related CVD mortality between 2015 and 2019. Disparities existed among different sexes, ethnicities, and areas. Actions to prevent and manage hypertension among patients with NCDs are required to reduce the high mortality rates and minimize disparities.

Leveraging Natural Learning Processing to Uncover Themes in Clinical Notes of Patients Admitted for Heart Failure

Heart failure occurs when the heart is not able to pump blood and oxygen to support other organs in the body as it should. Treatments include medications and sometimes hospitalization. Patients with heart failure can have both cardiovascular as well as non-cardiovascular comorbidities. Clinical notes of patients with heart failure can be analyzed to gain insight into the topics discussed in these notes and the major comorbidities in these patients. In this regard, we apply machine learning techniques, such as topic modeling, to identify the major themes found in the clinical notes specific to the procedures performed on 1,200 patients admitted for heart failure at the University of Illinois Hospital and Health Sciences System (UI Health). Topic modeling revealed five hidden themes in these clinical notes, including one related to heart disease comorbidities.

Allergic asthma aggravates angiotensin Ⅱ-induced cardiac remodeling in mice

Cardiovascular disease remains the leading cause of death globally, and heart failure (HF) represents its terminal stage. Asthma, one of the most common chronic diseases, has been reported to be associated with an increased risk of cardiovascular disease. However, the link between asthma and HF has rarely been studied, and the possible mechanisms by which asthma affects HF are unclear. This study aimed to explore the influence of asthma on HF and the possible mechanisms. We analyzed data from the National Health and Nutrition Examination Survey and found a higher prevalence of HF among asthmatic individuals, and identified an independent association between HF and asthma. Subsequently, we produced mice with concurrent ovalbumin (OVA) sensitization-induced allergic asthma and angiotensin Ⅱ infusion-induced cardiac remodeling to explore the effect of asthma on cardiac remodeling in vivo. The results showed that OVA-induced asthma impaired heart function and aggravated cardiac remodeling in mice. We also found that OVA sensitization increased the expression levels of immunoglobulin E (IgE) in serum and IgE receptor (FcεR1) in the heart, and enhanced the activation of downstream signaling molecules of IgE-FcεR1 in the heart. Importantly, blockage of IgE-FcεR1 using FcεR1-deficient mice or an anti-IgE antibody prevented asthma-induced decline of cardiac function, and alleviated cardiac remodeling. These findings demonstrate the adverse effects of allergic asthma on the heart, and suggest the potential application of anti-IgE therapy in the treatment of asthma complicated with heart conditions.
