Vascular health of fathers with history of intracytoplasmic sperm injection

OBJECTIVE

Studies suggest that men who undergo assisted reproductive technologies (ART) may have a higher risk of cardiovascular disease; however, limited data on this matter is available. This observational pilot study aimed to investigate the overall vascular health of fathers with history of intracytoplasmic sperm injection (ICSI) compared to fathers whose partners conceived spontaneously.

METHODS

Diet quality, physical activity, sedentary behavior as well as overall vascular function including the assessment of pulse wave analysis, intima-media thickness (cIMT), arterial stiffness of the common carotid artery (CCA) and blood lipids, were evaluated.

RESULTS

A total of 34 fathers with history of ICSI and 29 controls (48.49 [46.32 - 57.09] years vs. 47.19 [40.62 - 55.18] years, p = 0.061) were included. After adjusting for age, no significantly increased cardiovascular risk was detected regarding vascular function.

CONCLUSIONS

The results suggest an unaltered cardiovascular risk profile in fathers with history of ICSI. In the future, prospective multicenter studies are required to validate these preliminary results.

The role of sacubitril/valsartan in abnormal renal function patients combined with heart failure: a meta-analysis and systematic analysis

AIMS

This study aimed to investigate the efficacy and safety of sacubitril/valsartan in abnormal renal function (eGFR < 60 ml/min/1.73m2) patients combined with heart failure based on randomized controlled trials (RCTs) and observational studies.

METHODS

The Embase, PubMed and the Cochrane Library were searched for relevant studies from inception to December 2023. Dichotomous variables were described as event counts with the odds ratio (OR) and 95% confidence interval (CI) values. Continuous variables were expressed as mean standard deviation (SD) with 95% CIs.

RESULTS

A total of 6 RCTs and 8 observational studies were included, involving 17335 eGFR below 60 ml/min/1.73m2 patients combined with heart failure. In terms of efficacy, we analyzed the incidence of cardiovascular events and found that sacubitril/valsartan significantly reduced the risk of cardiovascular death or heart failure hospitalization in chronic kidney disease (CKD) stages 3-5 patients with heart failure (OR: 0.65, 95%CI: 0.54-0.78). Moreover, sacubitril/valsartan prevented the serum creatinine elevation (OR: 0.81, 95%CI: 0.68-0.95), the eGFR decline (OR: 0.83, 95% CI: 0.73-0.95) and the development of end-stage renal disease in this population (OR:0.73, 95%CI:0.60-0.89). As for safety outcomes, we did not find that the rate of hyperkalemia (OR:1.31, 95%CI:0.79-2.17) and hypotension (OR:1.57, 95%CI:0.94-2.62) were increased in sacubitril/valsartan group among CKD stages 3-5 patients with heart failure.

CONCLUSIONS

Our meta-analysis proves that sacubitril/valsartan has a favorable effect on cardiac function without obvious risk of adverse events in abnormal renal function patients combined with heart failure, indicating that sacubitril/valsartan has the potential to become perspective treatment for these patients.

The association of metabolic dysfunction-associated steatotic liver disease (MASLD) with the risk of myocardial infarction: a systematic review and meta-analysis

Objective While studies have documented how metabolic dysfunction-associated steatotic liver disease (MASLD) can contribute to cardiovascular disease (CVD), whether MASLD is associated with myocardial infarction (MI) remains debateable. Herein, we systematically reviewed published articles and performed a meta-analysis to determine the relationship between MASLD and MI risk.Methods PubMed, MEDLINE, Embase, Web of Science, CNKI, CBM, VIP, and WanFang databases were searched, and the DerSimonian Laird method was used to obtain hazard ratios (HRs) for binary variables to assess the correlation between MASLD and MI risk. Subgroup analyses for the study region, MASLD diagnosis, quality score, study design, and follow-up time were conducted simultaneously for the selected studies retrieved from the time of database establishment to March 2022. All study procedures were independently conducted by two investigators.Results The final analysis included seven articles, including eight prospective and two retrospective cohort studies. The MI risk was higher among MASLD patients than among non-MASLD patients (HR = 1.26; 95% CI: 1.08-1.47, p = 0.003). The results of the subgroup analysis of the study region revealed an association of MASLD with MI risk among Americans and Asians, but not in Europeans. Subgroup analyses of MASLD diagnosis showed that ultrasonography and other (fatty liver index[FLI] and computed tomography [CT)]) diagnostic methods, but not international classification of disease (ICD), increased the risk of MI. Subgroup analysis of the study design demonstrated a stronger relationship between MASLD and MI in retrospective studies but not in prospective studies. Subgroup analysis based on the follow-up duration revealed the association of MASLD with MI risk in cases with < 3 years of follow-up but not with ≥3 years of follow-up.Conclusion MASLD increases the risk of MI, independent of traditional risk factors.

Implications of pulse wave velocity and central pulse pressure in heart failure with reduced ejection fraction

BACKGROUND

Carotid-femoral pulse wave velocity (cfPWV) and central pulse pressure (PP) are recognised as significant indicators of vascular health and predictors of cardiovascular outcomes. In this study, associations between central hemodynamics and left ventricular (LV) echocardiographic parameters were investigated in subjects with heart failure with reduced ejection fraction (HFrEF), comparing the results to healthy individuals.

METHODS AND RESULTS

This cross-sectional prospective controlled study included 50 subjects with HFrEF [mean LV ejection fraction (EF) 26 ± 6.5%] and 30 healthy controls (mean LVEF 65.9 ± 5.3%). Pulse wave analysis (PWA) and carotid-femoral pulse wave velocity (cfPWV) were used to measure central hemodynamics and arterial stiffness. The HFrEF group displayed higher cfPWV (8.2 vs. 7.2 m/s, p = 0.007) and lower central (111.3 vs. 121.7 mmHg, p = 0.001) and peripheral (120.1 vs. 131.5 mmHg, p = 0.002) systolic blood pressure. Central pulse pressure (PP) was comparable between the two groups (37.6 vs. 40.4 mmHg, p = 0.169). In the HFrEF group, cfPWV significantly correlated with left ventricular end-diastolic volume (LVEDV) index (mL/m2) and LVEF, with LVEDV index being a significant independent predictor of cfPWV (R2 = 0.42, p = 0.003). Central PP was significantly associated with heart rate, LVEF and LVEDV index, with the latter being a significant independent predictor of central PP (R2 = 0.41, p < 0.001). These correlations were not observed in healthy controls.

CONCLUSIONS

Significant associations between central hemodynamic measures and LV echocardiographic parameters were identified, suggesting the potential to use PWA and cfPWV as possible tools for managing HFrEF.

Survival and causes of death in patients with alpha and beta-thalassemia in Northern Thailand

BACKGROUND

Thalassemia is the most prevalent hereditary anaemia worldwide. Severe forms of thalassemia can lead to reduced life expectancy due to disease-related complications.

OBJECTIVES

To investigate the survival of thalassemia patients across varying disease severity, causes of death and related clinical factors.

PATIENTS AND METHODS

We conducted a retrospective review of thalassemia patients who received medical care at Chiang Mai University Hospital. The analysis focused on survival outcomes, and potential associations between clinical factors and patient survival.

RESULTS

A total of 789 patients were included in our study cohort. Among them, 38.1% had Hb H disease, 35.4% had Hb E/beta-thalassemia and 26.5% had beta-thalassemia major. Half of the patients (50.1%) required regular transfusions. Sixty-five patients (8.2%) had deceased. The predominant causes of mortality were infection-related (36.9%) and cardiac complications (27.7%). Transfusion-dependent thalassemia (TDT) (adjusted HR 3.68, 95% CI 1.39-9.72, p = 0.008) and a mean serum ferritin level ≥3000 ng/mL (adjusted HR 4.18, 95% CI 2.20-7.92, p < 0.001) were independently associated with poorer survival.

CONCLUSIONS

Our study highlights the primary contributors to mortality in patients with thalassemia as infection-related issues and cardiac complications. It also underscores the significant impact of TDT and elevated serum ferritin levels on the survival of thalassemia patients.

Age shock index and age-modified shock index are valuable bedside prognostic tools for postdischarge mortality in ST-elevation myocardial infarction patients

BACKGROUND

The incidence of mortality is considerable after ST-elevation myocardial infarction (STEMI) hospitalization; risk assessment is needed to guide postdischarge management. Age shock index (SI) and age modified shock index (MSI) were described as useful prognosis instruments; nevertheless, their predictive effect on short and long-term postdischarge mortality has not yet been sufficiently confirmed.

METHODS

This analysis included 3389 prospective patients enrolled from 2016 to 2018. Endpoints were postdischarge mortality within 30 days and from 30 days to 1 year. Hazard ratios (HRs) were evaluated by Cox proportional-hazards regression. Predictive performances were assessed by area under the curve (AUC), integrated discrimination improvement (IDI), net reclassification improvement (NRI) and decision curve analysis (DCA) and compared with TIMI risk score and GRACE score.

RESULTS

The AUCs were 0.753, 0.746 for age SI and 0.755, 0.755 for age MSI for short- and long-term postdischarge mortality. No significant AUC differences and NRI were observed compared with the classic scores; decreased IDI was observed especially for long-term postdischarge mortality. Multivariate analysis revealed significantly higher short- and long-term postdischarge mortality for patients with high age SI (HR: 5.44 (2.73-10.85), 5.34(3.18-8.96)), high age MSI (HR: 4.17(1.78-9.79), 5.75(3.20-10.31)) compared to counterparts with low indices. DCA observed comparable clinical usefulness for predicting short-term postdischarge mortality. Furthermore, age SI and age MSI were not significantly associated with postdischarge prognosis for patients who received fibrinolysis.

CONCLUSIONS

Age SI and age MSI were valuable instruments to identify high postdischarge mortality with comparable predictive ability compared with the classic scores, especially for events within 30 days after hospitalization.

Translating proof-of-concept for platelet slip into improved antithrombotic therapeutic regimens

Platelets are central to thrombosis. Research at the intersection of biological and physical sciences provides proof-of-concept for shear rate-dependent platelet slip at vascular stenosis and near device surfaces. Platelet slip extends the observed biological "slip-bonds" to the boundary of functional gliding without contact. As a result, there is diminished engagement of the coagulation cascade by platelets at these surfaces. Comprehending platelet slip would more precisely direct antithrombotic regimens for different shear environments, including for percutaneous coronary intervention (PCI). In this brief report we promote translation of the proof-of-concept for platelet slip into improved antithrombotic regimens by: (1) reviewing new supporting basic biological science and clinical research for platelet slip; (2) hypothesizing the principal variables that affect platelet slip; (3) applying the consequent construct model in support of-and in some cases to challenge-relevant contemporary guidelines and their foundations (including for urgent, higher-risk PCI); and (4) suggesting future research pathways (both basic and clinical). Should future research demonstrate, explain and control platelet slip, then a paradigm shift for choosing and recommending antithrombotic regimens based on predicted shear rate should follow. Improved clinical outcomes with decreased complications accompanying this paradigm shift for higher-risk PCI would also result in substantive cost savings.

Valve-in-valve transcatheter mitral valve replacement versus redo-surgical mitral valve replacement for degenerated bioprosthetic mitral valves: A systematic review and meta-analysis

Bioprosthetic mitral valve degeneration is traditionally treated with Redo-SMVR, but the latest ViV-TMVR procedure offers a less invasive and lower risk alternative. A systematic literature search was conducted on Cochrane Central, Scopus, and Medline (PubMed interface) electronic databases from inception till 15th April 2024. We used risk ratios (RR) for dichotomous outcomes and mean differences (MD) for continuous outcomes. We included a total of eleven studies with 11,931 patients in the final quantitative and qualitative analysis. When comparing ViV-TMVR with Redo-SMVR, no significant difference was found for 30-day mortality (P = 0.13) and 1-year mortality (P = 0.91), whereas patients in the ViV-TMVR showed significantly reduced incidence of stroke (P < 0.00001), In-hospital mortality (P), bleeding complications (P = 0.003), AKI (P = 0.0006), arrhythmias (P = 0.01), LVOT obstruction (P = 0.04), and PPI (P < 0.00001). Furthermore, no significant difference was observed between either group when comparing vascular complications (P = 0.97), 2-year mortality (P = 0.60) and 3-year mortality. ViV-TMVR was associated with a significant risk of paravalvular leakage (P = 0.008). Although, ViV-TMVR reduces the risk of complications associated with Redo-SMVR, larger studies are imperative to reach conclusive results.

Exploring the role of pericardial miRNAs and exosomes in modulating cardiac fibrosis

The potential of the pericardial space as a therapeutic delivery tool for cardiac fibrosis and heart failure (HF) treatment has yet to be elucidated. Recently, miRNAs and exosomes have been discovered to be present in human pericardial fluid (PF). Novel studies have shown characteristic human PF miRNA compositions associated with cardiac diseases and higher miRNA expressions in PF compared to peripheral blood. Five key studies found differentially expressed miRNAs in HF, angina pectoris, aortic stenosis, ventricular tachycardia, and congenital heart diseases with either atrial fibrillation or sinus rhythm. As miRNA-based therapeutics for cardiac fibrosis and HF showed promising results in several in vivo studies for multiple miRNAs, we hypothesize a potential role of miRNA-based therapeutics delivered through the pericardial cavity. This is underlined by the favorable results of the first phase 1b clinical trial in this emerging field. Presenting the first human miRNA antisense drug trial, inhibition of miR-132 by intravenous administration of a novel antisense oligonucleotide, CDR132L, established efficacy in reducing miR-132 in plasma samples in a dose-dependent manner. We screened the literature, provided an overview of the miRNAs and exosomes present in PF, and drew a connection to those miRNAs previously elucidated in cardiac fibrosis and HF. Further, we speculate about clinical implications and potential delivery methods.

Advances in macrophage metabolic reprogramming in myocardial ischemia-reperfusion

Acute myocardial infarction (AMI) is the leading cause of death worldwide, and reperfusion therapy is a critical therapeutic approach to reduce myocardial ischemic injury and minimize infarct size. However, ischemia/reperfusion (I/R) itself also causes myocardial injury, and inflammation is an essential mechanism by which it leads to myocardial injury, with macrophages as crucial immune cells in this process. Macrophages are innate immune cells that maintain tissue homeostasis, host defence during pathogen infection, and repair during tissue injury. During the acute phase of I/R, M1-type macrophages generate a pro-inflammatory milieu, clear necrotic myocardial tissue, and further recruit mononuclear (CCR2+) macrophages. Over time, the reparative (M2 type) macrophages gradually became dominant. In recent years, metabolic studies have shown a clear correlation between the metabolic profile of macrophages and their phenotype and function. M1-type macrophages are mainly characterized by glycolytic energy supply, and their tricarboxylic acid (TCA) cycle and mitochondrial oxidative phosphorylation (OXPHOS) processes are impaired. In contrast, M2 macrophages rely primarily on OXPHOS for energy. Changing the metabolic profile of macrophages can alter the macrophage phenotype. Altered energy pathways are also present in macrophages during I/R, and intervention in this process contributes to earlier and greater M2 macrophage infiltration, which may be a potential target for the treatment of myocardial I/R injury. Therefore, this paper mainly reviews the characteristics of macrophage energy metabolism alteration and phenotypic transition during I/R and its mechanism of mediating myocardial injury to provide a basis for further research in this field.

PCSK9 inhibitor added to high-intensity statin therapy to prevent cardiovascular events in patients with acute coronary syndrome after percutaneous coronary intervention: a randomized, double- blind, placebo-controlled, multicenter SHAWN study

BACKGROUND

It is currently uncertain whether the combination of a proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor and high-intensity statin treatment can effectively reduce cardiovascular events in patients with acute coronary syndrome (ACS) who have undergone percutaneous coronary intervention (PCI) for culprit lesions.

METHODS

This study protocol describes a double-blind, randomized, placebo-controlled, multicenter study aiming to investigate the efficacy and safety of combining a PCSK9 inhibitor with high-intensity statin therapy in patients with ACS following PCI. A total of 1,212 patients with ACS and multiple lesions will be enrolled and randomly assigned to receive either PCSK9 inhibitor plus high-intensity statin therapy or high-intensity statin monotherapy. The randomization process will be stratified by sites, diabetes, initial presentation and use of stable (≥4 weeks) statin treatment at presentation. PCSK 9 inhibitor or its placebo is injected within 4 hours after PCI for the culprit lesion. The primary endpoint is the composite of cardiovascular death, myocardial infarction, stroke, re-hospitalization due to ACS or heart failure, or any ischemia-driven coronary revascularization at 1-year follow-up between 2 groups. Safety endpoints mean PCSK 9 inhibitor and statin intolerance.

CONCLUSION

The SHAWN study has been specifically designed to evaluate the effectiveness and safety of adding a PCSK9 inhibitor to high-intensity statin therapy in patients who have experienced ACS following PCI. The primary objective of this study is to generate new evidence regarding the potential benefits of combining a PCSK9 inhibitor with high-intensity statin treatment in reducing cardiovascular events among these patients.

Inferior vena CAVA and lung ultraSound-guided therapy in acute heart failure: A randomized pilot study (CAVAL US-AHF study)

BACKGROUND

The optimal assessment of systemic and lung decongestion during acute heart failure is not clearly defined. We evaluated whether inferior vena cava (IVC) and pulmonary ultrasound (CAVAL US) guided therapy is superior to standard care in reducing subclinical congestion at discharge in patients with AHF.

METHODS

CAVAL US-AHF was an investigator-initiated, single-center, single-blind, randomized controlled trial. A daily quantitative ultrasound protocol using the 8-zone method was used and treatment was adjusted according to an algorithm. The primary endpoint was the presence of more than 5 B-lines and/or an increase in IVC diameter and collapsibility at discharge. And secondary endpoint exploratory outcome was the composite of readmission for HF, unplanned visit for worsening HF or death at 90 days RESULTS: Sixty patients were randomized to CAVAL US (n = 30) or control (n = 30). The primary endpoint was achieved in 4 patients (13.3%) in the CAVAL US group and 20 patients (66.6%) in the control group (P < .001). A significant reduction in HF readmission, unplanned visit for worsening HF or death at 90 days was seen in the CAVAL US group (13.3% vs 36.7%; log rank P = .038). Other endpoints such as NT-proBNP reduction at discharge showed a nonstatistically significant reduction in the CAVAL US group (48% IQR 27-67 vs 37% -3-59; P = .09). Safety outcomes were similar in both groups.

CONCLUSION

IVC and lung ultrasound-guided therapy in AHF patients significantly reduced subclinical congestion at discharge. CAVAL US-AHF provides preliminary evidence for the potential use of a simple technique to guide decongestive therapy during hospitalization for AHF, which may reduce the composite outcome at 90 days.

PCSK9 gene variations in the clinical setting of premature cardiovascular disease: A critical appraisal

INTRODUCTION

Information about PCSK9 gene variations and its association with cardiovascular (CV) disease is controversial. We aimed to evaluate 3 reported polymorphisms in PSCK9 in a cohort of young patients with myocardial infarction with ST segment elevation (STEMI).

METHODS

Retrospective study of consecutive patients with premature STEMI (2018-2023). 216 patients with STEMI due atherothrombotic coronary artery disease (CAD), confirmed by coronary angiogram, were included. We genotyped 3 polymorphisms in PCSK9 (rs12117661, rs2483205, rs505151) in 207 patients (DNA unavailable in 9) and a control group (N = 200).

RESULTS

Mean age 49.4 ± 6,6 years (82.4% men). Genotypes frequencies distribution in patient's and control's cohorts did not deviate from the expected by Hardy-Weinberg equilibrium and there were no significant differences between patients and controls. Among patients, we did not find any association between PSCK9 genotypes and clinical variables (gender, age, CV risk factors, cholesterol levels, family history of premature CAD or number of coronary arteries affected).

CONCLUSION

We did not find any association between PSCK9 genotypes (RS12117661, RS2483205 and RS505151) and any CV risk factors or the extent of CAD in a cohort of patients with premature STEMI. There were not differences in the genotype distribution between patients and controls.

Quantification of anatomical aortic valve area by multi-detector computed tomography: A pilot 3D-morphological modeling of the stenotic aortic valve

BACKGROUND

Aortic-valve-stenosis (AS) is a frequent degenerative valvular-disease and carries dismal outcome under-medical-treatment. Transvalvular pressure gradient reflects severity of the valve-disease but is highly dependent on flow-conditions and on other valvular/aortic characteristics. Alternatively, aortic-valve-area (AVA) represents a measure of aortic-valve lesion severity conceptually essential and practically widely-recognized but exhibits multiple-limitations.

METHODS

We analyzed the 4D multi-detector computed tomography(MDCT) of 20 randomly selected patients with severe AS. For each-patient, we generated the 3D-model of the valve and of its calcifications, and we computed the anatomical AVA accounting for the 3D-morphology of the leaflets in three-different-ways. Finally, we compared our results vs. Doppler-based AVAE measurements and vs. 2D-planimetric AVA-measurements.

RESULTS

3D-reconstruction and identification of the cusps were successful in 90% of the cases. The calcification patterns where highly-variable over patients, ranging from multiple small deposits to wide and c-shaped deposits running from commissure-to-commissure. AVAE was 82 ± 15 mm2. When segmenting 18 image planes, AVATight, AVAProj-Ann, AVAProj-Tip and their average AVAAve were equal to 80 ± 16, 88 ± 20, 93 ± 21 and 87 ± 19 mm2, respectively, while AVAPlan was equal to 143 ± 50 mm2. Linear-regression of the three measurements vs. AVAE yielded regression slopes equal to 1.26, 1.13 and 0.93 for AVAProj-Ann, AVAProj-Tip and AVATight, respectively. The respective Pearson-coefficients were 0.85,0.86 and 0.90. Conversely, when comparing AVAPlan vs. AVAE, linear regression yielded a slope of 1.73 and a Pearson coefficient of 0.53.

CONCLUSIONS

We described a new-method to obtain a set of flow-independent quantifications that complement pressure gradient measurements and combine the advantages of previously proposed methods, while bypassing the corresponding-limitations.

Optimal door-to-balloon time for primary percutaneous coronary intervention for ST-elevation myocardial infarction

BACKGROUND

Door-to-balloon time (DTBT) for ST-elevation myocardial infarction (STEMI) is a performance metric by which primary percutaneous coronary intervention (PPCI) services are assessed.

METHODS

Consecutive patients presenting with STEMI undergoing PPCI between January 2007 to December 2019 from the Singapore Myocardial Infarction Registry were included. Patients were stratified based on DTBT (≤60 min, 61-90 min, 91-180 min) and Killip status (I-III vs. IV). Outcomes assessed included all-cause mortality and major adverse cardiovascular events (MACE) at 30-days and 1-year.

RESULTS

In total, 13,823 patients were included, with 82.59% achieving DTBT ≤90 min and 49.77% achieving DTBT ≤60 min. For Killip I-III (n = 11,591,83.85%), the median DTBT was 60[46-78]min. The 30-day all-cause mortality for DTBT of ≤60 min, 61-90 min and 91-180 min was 1.08%, 2.17% and 4.33% respectively (p < 0.001). On multivariate analysis, however, there was no significant difference for 30-day and 1-year outcomes across all DTBT (p > 0.05). For Killip IV, the median DTBT was 68[51-91]min. The 30-day all-cause mortality for DTBT of ≤60 min, 61-90 min and 91-180 min was 11.74%, 20.48% and 35.06% respectively (p < 0.001). On multivariate analysis for 30-day and 1-year outcomes, DTBT 91-180 min was an independent predictor of worse outcomes (p < 0.05), but there was no significant difference between DTBT of ≤60 min and 61-90 min (p > 0.05).

CONCLUSION

In Killip I-III patients, DTBT had no significant impact on outcomes upon adjustment for confounders. Conversely, for Killip IV patients, a DTBT of >90 min was associated with significantly higher adverse outcomes, with no differences between a DTBT of ≤60 min vs. 61-90 min. Outcomes in STEMI involve a complex interplay of factors and recommendations of a lowered DTBT of ≤60 min will require further evaluation.

Balloon aortic valvuloplasty bridge to transcatheter aortic valve replacement is associated with worse in-hospital mortality

BACKGROUND

Balloon aortic valvuloplasty (BAV) has gained renewed interest as a bridge to transcatheter aortic valve replacement (TAVR) for patients with aortic stenosis (AS). However, it is unclear whether they patients should undergo TAVR directly or receive a staged bridge to BAV before TAVR is unclear. We used a national database to examine the association between BAV and TAVR in patients with TAVR and its effect on in-hospital mortality.

METHODS

Using the nationwide inpatient database of the Japanese registry of all cardiac and vascular diseases and the combination of the diagnosis procedure combination, we retrospectively analyzed 27,600 patients with AS who underwent TAVR between October 2013 and March 2021. Outcomes of the direct TAVR group (n = 27,387) were compared with those of the BAV bridge to TAVR group (n = 213), which received BAV at least 1 day before TAVR.

RESULTS

The median age was 85 (interquartile range: 82-88) years, with 33.3% (n = 9188) being male. Unplanned/emergent admissions increased with TAVR, whereas the use of BAV bridge to TAVR decreased. The in-hospital mortality rate was 1.3% and decreased over time. However, the BAV bridge to TAVR had a significantly higher in-hospital mortality than direct TAVR (5.6% vs. 1.3%; p < .0001). Factors associated with in-hospital mortality included age, body mass index, chronic renal disease, percutaneous coronary intervention, and BAV bridge to TAVR.

CONCLUSIONS

In unplanned/emergent and planned admission settings, the in-hospital mortality rate for BAV bridge to TAVR is worse than that for direct TAVR. Practical criteria for BAV bridge to TAVR should be proposed to improve outcomes.

Clean air policy reduces the atherogenic lipid profile levels: Results from China Health Evaluation And risk Reduction through nationwide Teamwork (ChinaHEART) Study

Evidence of the associations between long-term exposure to PM2.5 and O3 and human blood lipid concentrations is abundant yet inconclusive. Whether clean air policies could improve lipid profiles remains unclear. In total, 2979312 participants from a Chinese nationwide prospective study were included. For cross-sectional analyses, linear mixed-effects models were utilized to assess the associations of pollutants with lipid profiles (TC, LDL-C, TG, HDL-C). For longitudinal analyses, a quasi-experimental design and difference-in-differences models were employed to investigate the impact of China's Clean Air Act. In the cross-sectional analyses, each IQR increase in PM2.5 was associated with 2.49 % (95 % CI: 2.36 %, 2.62 %), 2.51 % (95 % CI: 2.26 %, 2.75 %), 3.94 % (95 % CI: 3.65 %, 4.23 %), and 1.54 % (95 % CI: 1.38 %, 1.70 %) increases in TC, LDL-C, TG, and HDL-C, respectively. For each IQR increase in O3, TC, LDL-C, TG, and HDL-C changed by 1.06 % (95 % CI: 0.95 %, 1.17 %), 1.21 % (95 % CI: 1.01 %, 1.42 %), 1.78 % (95 % CI: 1.54 %, 2.02 %), and -0.63 % (95 % CI: -0.76 %, -0.49 %), respectively. Longitudinal analyses showed that the intervention group experienced greater TC, LDL-C, and HDL-C reductions (1.77 %, 4.26 %, and 7.70 %, respectively). Our findings suggest that clean air policies could improve lipid metabolism and should be implemented in countries with heavy air pollution burdens.

Prognostic impact of quantitative flow ratio (QFR)-consistent complete revascularization in patients with myocardial infarction and multivessel coronary artery disease

BACKGROUND

Complete revascularization is associated with improved outcomes in patients with myocardial infarction and multivessel coronary artery disease. Quantitative flow ratio (QFR) represents an emerging angiography-based tool for functional lesion assessment. The present study investigated the prognostic impact of QFR-consistent complete revascularization in patients with myocardial infarction and multivessel disease.

METHODS

A total of 792 patients with myocardial infarction and multivessel disease were enrolled in the analysis. Post-hoc QFR analyses of 1,320 nonculprit vessels were performed by investigators blinded to clinical outcomes. The primary endpoint was a composite of all-cause death, nonculprit vessel related nonfatal myocardial infarction, and ischemia-driven revascularization at 2 years after index myocardial infarction. Patients were stratified into a QFR-consistent PCI group (n = 646) and a QFR-inconsistent PCI group (n = 146), based on whether the intervention was congruent with the QFR-determined functional significance of the nonculprit lesions.

RESULTS

The primary endpoint occurred in a total of 22 patients (3.4%) in the QFR-consistent PCI group and in 27 patients (18.5%) in the QFR-inconsistent group (HR 0.17, 95% CI 0.10-0.30, P < .001).The difference in the primary endpoint was driven by reduced rates of nonfatal myocardial infarction (2.0% vs. 15.1%; HR 0.13, 95% CI 0.06-0.25; P < .001) and ischemia-driven revascularization (1.2% vs. 5.5%; HR 0.21, 95% CI 0.08-0.57; P = .001) in the QFR-consistent PCI group.

CONCLUSIONS

Among patients with myocardial infarction and multivessel disease, a QFR-consistent complete revascularization was associated with a reduced risk of all-cause mortality, nonfatal myocardial infarction, and ischemia-driven revascularization. These findings underline the value of angiography-based functional lesion assessment for personalized revascularization strategies.

Impact of Wildfire Smoke on Acute Illness

Climate change increases wildfire smoke exposure. Inhaled smoke causes inflammation, oxidative stress, and coagulation, which exacerbate cardiovascular and respiratory disease while worsening obstetric and neonatal outcomes.

The LDL cumulative exposure hypothesis: evidence and practical applications

The trapping of LDL and other apolipoprotein B-containing lipoproteins within the artery wall causes atherosclerosis. As more LDL becomes trapped within the artery wall over time, the atherosclerotic plaque burden gradually increases, raising the risk of an acute cardiovascular event. Therefore, the biological effect of LDL on the risk of atherosclerotic cardiovascular disease (ASCVD) depends on both the magnitude and duration of exposure. Maintaining low levels of LDL-cholesterol (LDL-C) over time decreases the number of LDL particles trapped within the artery wall, slows the progression of atherosclerosis and, by delaying the age at which mature atherosclerotic plaques develop, substantially reduces the lifetime risk of ASCVD events. Summing LDL-C measurements over time to calculate cumulative exposure to LDL generates a unique biomarker that captures both the magnitude and duration of exposure, which facilitates the estimation of the absolute risk of having an acute cardiovascular event at any point in time. Titrating LDL-C lowering to keep cumulative exposure to LDL below the threshold at which acute cardiovascular events occur can effectively prevent ASCVD. In this Review, we provide the first comprehensive overview of how the LDL cumulative exposure hypothesis can guide the prevention of ASCVD. We also discuss the benefits of maintaining lower LDL-C levels over time and how this knowledge can be used to inform clinical practice guidelines as well as to design novel primary prevention trials and ASCVD prevention programmes.

International Society for Heart and Lung Transplantation Guidelines for the Evaluation and Care of Cardiac Transplant Candidates-2024

The "International Society for Heart and Lung Transplantation Guidelines for the Evaluation and Care of Cardiac Transplant Candidates-2024" updates and replaces the "Listing Criteria for Heart Transplantation: International Society for Heart and Lung Transplantation Guidelines for the Care of Cardiac Transplant Candidates-2006" and the "2016 International Society for Heart Lung Transplantation Listing Criteria for Heart Transplantation: A 10-year Update." The document aims to provide tools to help integrate the numerous variables involved in evaluating patients for transplantation, emphasizing updating the collaborative treatment while waiting for a transplant. There have been significant practice-changing developments in the care of heart transplant recipients since the publication of the International Society for Heart and Lung Transplantation (ISHLT) guidelines in 2006 and the 10-year update in 2016. The changes pertain to 3 aspects of heart transplantation: (1) patient selection criteria, (2) care of selected patient populations, and (3) durable mechanical support. To address these issues, 3 task forces were assembled. Each task force was cochaired by a pediatric heart transplant physician with the specific mandate to highlight issues unique to the pediatric heart transplant population and ensure their adequate representation. This guideline was harmonized with other ISHLT guidelines published through November 2023. The 2024 ISHLT guidelines for the evaluation and care of cardiac transplant candidates provide recommendations based on contemporary scientific evidence and patient management flow diagrams. The American College of Cardiology and American Heart Association modular knowledge chunk format has been implemented, allowing guideline information to be grouped into discrete packages (or modules) of information on a disease-specific topic or management issue. Aiming to improve the quality of care for heart transplant candidates, the recommendations present an evidence-based approach.

Prognostic roles of neutrophil-lymphocyte, monocyte-lymphocyte and platelet-lymphocyte ratios for long-term all-cause mortality in heart failure

Background

Heart failure (HF) and inflammation have a bidirectional relation leading to activation and adaptation of multiple cellular lines, including leucocyte subtypes and platelets. We aimed to assess and compare the predictive value of the neutrophil-lymphocyte (NLR), monocyte-lymphocyte (MLR) and platelet-lymphocyte (PLR) ratios for all-cause long-term mortality in HF.

Methods

This is an observational retrospective cohort study that included patients from the HI-HF cohort that survived the initial hospitalization. Vital status and survival time were assessed in June 2020.

Results

We analyzed 1018 HF patients with a mean age of 72.32 ± 10.29 years and 53.54 % women. All-cause long-term mortality was 38.21 % after a median follow-up time of 68 [38 - 82] months. NLR (AUC 0.667, 95 %CI 0.637 - 0.697), MLR (AUC 0.670, 95 %CI 0.640 - 0.700) and PLR (AUC 0.606, 95 %CI 0.574 - 0.636) were predictors of all-cause mortality. In multivariable Cox proportional hazards analysis, NLR≥3.56 was the only hematological index independent predictor of fatality (HR 1.36, 95 %CI 1.05 - 1.76).

Conclusions

Of the three hematological indices, NLR was the only independent predictor of all-cause long-term mortality of HF patients. We suggest NLR≥3.56 as an auxiliary prognostic biomarker for the evaluation of HF patients.

Echocardiography predictors of sustained sinus rhythm after cardioversion of supraventricular arrhythmia in patients with septic shock

PURPOSE

The echocardiography parameters may predict the maintenance of sinus rhythm after cardioversion of a supraventricular arrhythmia (SVA).

MATERIALS AND METHODS

Patients in septic shock with onset of an SVA, normal to moderately reduced LV systolic function (EF_LV˃̳35%) and on a continuous noradrenaline of <1.0 μg/kg.min were included. Echocardiography was performed at the arrhythmia onset, 1 h and 4 h post cardioversion on an infusion of propafenone or amiodarone.

RESULTS

Cardioversion was achieved in 96% of the 209 patients within a median time of 6(1.8-15.6)h, 134(64.1%) patients experienced at least one SVA recurrence after cardioversion. At 4 h the left atrial emptying fraction (LA_EF, cut-off 38.4%, AUC 0.69,p˂0.001), and transmitral A wave velocity-time-integral (Avti, cut-off 6.8 cm, AUC 0.65,p = 0.001) showed as limited predictors of a single arrhythmia recurrence. The LA_EF 44(36,49)%, (p = 0.005) and the Avti 8.65(7.13,9.50)cm, (p < 0.001) were associated with sustained sinus rhythm and decreased proportionally to increasing numbers of arrhythmia recurrences (p < 0.001 and p = 0.007, respectively). The enlarged left atrial end-systolic diameter at the arrhythmia onset (p = 0.04) and elevated systolic pulmonary artery pressure at 4 h (p = 0.007) were weak predictors of multiple(˃3) recurrences.

CONCLUSION

The LA_EF and Avti are related to arrhythmia recurrences post-cardioversion suggesting potential guidance to the choice between rhythm and rate control strategies.

Antithrombotic Therapy in Patients with Chronic Coronary Syndromes

The antithrombotic management of chronic coronary syndrome (CCS) involves a 6-month course of dual antiplatelet therapy (DAPT), followed by chronic aspirin therapy. In patients with a baseline indication for anticoagulation, a variable duration of triple antithrombotic therapy is administered, followed by dual antithrombotic therapy until the sixth month post-percutaneous coronary intervention (PCI), and ultimately a transition to chronic anticoagulation. However, advancements in stent technology reducing the risk of stent thrombosis and a growing focus on the impact of bleeding on prognosis have prompted the development of new therapeutic strategies. These strategies aim to enhance protection against ischemic events in the initial stages after PCI while mitigating the risk of bleeding in the long term. This article delineates the therapeutic strategies outlined in European and American guidelines for CCS management, with special attention to investigational strategies.

Effect of Atherogenic Index of Plasma on Pre-Percutaneous Coronary Intervention Thrombolysis in Myocardial Infarction Flow in Patients With ST Elevation Myocardial Infarction

Dyslipidemia is an important risk factor for cardiovascular morbidity and mortality. Although low-density lipoprotein (LDL) is primarily responsible, the importance of triglyceride (TG) and high-density lipoprotein (HDL) has also been recognized. The present study investigated the effect of the atherogenic index of plasma (AIP), in which atherogenic and protective lipoproteins were evaluated together, on the initial flow in patients with ST elevation myocardial infarction. AIP was calculated as log(TG/HDL-cholesterol). Patients included in the study (n = 1535) were divided into Thrombolysis in Myocardial Infarction (TIMI) flow grade 0 and >0. AIP was found to be significantly different between 2 groups (.55 ± .23 vs .67 ± .21; P < .001). AIP was an independent predictor for pre-intervention TIMI flow (Odds Ratio: 2.778). A moderate correlation was found between TIMI frame count measurements, calculated in patients with TIMI 2-3, and AIP (Pearson correlation coefficient: .63, P < .001). In the receiver operating characteristic analysis, AIP showed the highest area under curve (AUC) compared with other lipid parameters for predicting vascular patency. The AUC of AIP was .634, the cut-off value was .59, and the sensitivity and specificity were 67.6% and 68.4%, respectively (P < .001). In conclusion, AIP was found to be an important marker affecting pre-percutaneous coronary intervention TIMI flow.

In-silico heart model phantom to validate cardiac strain imaging

The quantification of cardiac strains as structural indices of cardiac function has a growing prevalence in clinical diagnosis. However, the highly heterogeneous four-dimensional (4D) cardiac motion challenges accurate "regional" strain quantification and leads to sizable differences in the estimated strains depending on the imaging modality and post-processing algorithm, limiting the translational potential of strains as incremental biomarkers of cardiac dysfunction. There remains a crucial need for a feasible benchmark that successfully replicates complex 4D cardiac kinematics to determine the reliability of strain calculation algorithms. In this study, we propose an in-silico heart phantom derived from finite element (FE) simulations to validate the quantification of 4D regional strains. First, as a proof-of-concept exercise, we created synthetic magnetic resonance (MR) images for a hollow thick-walled cylinder under pure torsion with an exact solution and demonstrated that "ground-truth" values can be recovered for the twist angle, which is also a key kinematic index in the heart. Next, we used mouse-specific FE simulations of cardiac kinematics to synthesize dynamic MR images by sampling various sectional planes of the left ventricle (LV). Strains were calculated using our recently developed non-rigid image registration (NRIR) framework in both problems. Moreover, we studied the effects of image quality on distorting regional strain calculations by conducting in-silico experiments for various LV configurations. Our studies offer a rigorous and feasible tool to standardize regional strain calculations to improve their clinical impact as incremental biomarkers.

Obicetrapib-the Rebirth of CETP Inhibitors?

PURPOSE OF REVIEW

To provide perspective on the current development status, and potential future role, of obicetrapib, a third-generation cholesterylester transfer protein (CETP) inhibitor. Obicetrapib has received recent attention following positive Phase II clinical trial data and initiation of Phase III trials for the treatment of dyslipidemia and atherosclerotic cardiovascular disease (ASCVD).

RECENT FINDINGS

The ROSE and ROSE2 trials are Phase II studies that examined the lipid lowering effects of obicetrapib in patients on pre-existing high-intensity statin therapy. Obicetrapib significantly reduced key dyslipidemia biomarkers including low density lipoprotein cholesterol (LDL-C), Apolipoprotein B (Apo B), and non-high-density lipoprotein cholesterol (non-HDL-C) while increasing high-density lipoprotein cholesterol (HDL-C). Four phase III clinical trials, including a cardiovascular outcomes trial, are ongoing. Preliminary data for obicetrapib shows favorable effects on dyslipidemia, which could theoretically lead to a decrease in ASCVD clinical events. Short-term safety data in preliminary studies shows no significant safety signals.

Statin treatment for primary and secondary prevention in elderly patients-a cross-sectional study in Stockholm, Sweden

BACKGROUND

Age is a major risk factor for atherosclerotic cardiovascular disease (CVD) and death, but there has been a debate about benefit-risk of statin treatment in the elderly with limited evidence on benefits for primary prevention, while there is strong evidence for its use in secondary prevention.

AIM

The aim of this study was to provide an overview of statin utilization in primary and secondary prevention for patients 75-84 years and ≥ 85 years in the Swedish capital Region Stockholm in 2019.

METHODS

This is a cross-sectional study based on the regional healthcare database VAL containing all diagnoses and dispensed prescription drugs for all 174,950 inhabitants ≥ 75 years old in the Stockholm Region. Prevalence and incidence were analyzed by sex, age, cardiovascular risk, substance, and the intensity of treatment.

RESULTS

A total of 35% of all individuals above the age of 75 in the region were treated with statins in 2019. The overall incidence in this age group was 31 patients per 1000 inhabitants. Men, individuals 75-84 compared to ≥ 85 years of age, and those with higher cardiovascular risk were treated to a greater extent. Simvastatin was used primarily by prevalent users and atorvastatin by incident users. The majority was treated with moderate-intensity dosages and fewer women received high intensity treatment.

CONCLUSIONS

Statins are widely prescribed in the elderly. Physicians seem to consider individual cardiovascular risk when deciding to initiate statin treatment for elderly patients, but here may still be some undertreatment among high-risk patients (especially women and elderly 85 + years) and some overtreatment among patients with low-risk for CVD.

Global epidemiology of heart failure

Heart failure (HF) is a heterogeneous clinical syndrome marked by substantial morbidity and mortality. The natural history of HF is well established; however, epidemiological data are continually evolving owing to demographic shifts, advances in treatment and variations in access to health care. Although the incidence of HF has stabilized or declined in high-income countries over the past decade, its prevalence continues to increase, driven by an ageing population, an increase in risk factors, the effectiveness of novel therapies and improved survival. This rise in prevalence is increasingly noted among younger adults and is accompanied by a shift towards HF with preserved ejection fraction. However, disparities exist in our epidemiological understanding of HF burden and progression in low-income and middle-income countries owing to the lack of comprehensive data in these regions. Therefore, the current epidemiological landscape of HF highlights the need for periodic surveillance and resource allocation tailored to geographically vulnerable areas. In this Review, we highlight global trends in the burden of HF, focusing on the variations across the spectrum of left ventricular ejection fraction. We also discuss evolving population-based estimates of HF incidence and prevalence, the risk factors for and aetiologies of this disease, and outcomes in different geographical regions and populations.

Prognostic significance of baseline low-density lipoprotein cholesterol in patients undergoing coronary revascularization; a report from the CREDO-Kyoto registry

BACKGROUND

The impact of very low baseline levels of low-density lipoprotein cholesterol (LDL-C) on patients with coronary artery disease remains unclear.

METHOD

We enrolled 39,439 patients of the pooled population from the CREDO-Kyoto registries Cohorts 1, 2, and 3. The study population consisted of 33,133 patients who had undergone their first coronary revascularization. We assessed the risk for mortality and cardiovascular events according to quintiles of the baseline LDL-C levels.

RESULTS

Patients in the very low LDL-C quintile (<85 mg/dL) had more comorbidities than those in the other quintiles. Lower LDL-C levels were strongly associated with anemia, thrombocytopenia, and end-stage renal disease. The cumulative 4-year incidence of all-cause death increased as LDL-C levels decreased (very low: 19.4 %, low: 14.5 %, intermediate: 11.1 %, high: 10.0 %, and very high: 9.2 %; p < 0.001), which was driven by both the early and late events. After adjusting for baseline characteristics, the adjusted risks of the very low and low LDL-C quintiles relative to the intermediate LDL-C quintile remained significant for all-cause death (very low: HR 1.29, 95 % CI 1.16-1.44, p < 0.001; low: HR 1.15, 95 % CI 1.03-1.29, p = 0.01). The excess adjusted risks of the lowest LDL-C quintile relative to the intermediate LDL-C quintile were significant for clinical outcomes such as cardiovascular death (HR 1.17, 95 % CI 1.01-1.35), non-cardiovascular death (HR 1.35, 95 % CI 1.15-1.60), sudden death (HR 1.44, 95 % CI 1.01-2.06), and heart failure admission (HR 1.11 95 % CI 1.01-1.22), while there was no excess risk for the lowest LDL-C quintile relative to the intermediate LDL-C quintile for myocardial infarction and stroke.

CONCLUSIONS

Lower baseline LDL-C levels were associated with more comorbidities and a significantly higher risk of death, regardless of cardiovascular or non-cardiovascular causes, in patients who underwent coronary revascularization.

Type I collagen-targeted liposome delivery of Serca2a modulates myocardium calcium homeostasis and reduces cardiac fibrosis induced by myocardial infarction

Fibrotic scarring and impaired myocardial calcium homeostasis serve as the two main factors in the pathology of heart failure following myocardial infarction (MI), leading to poor prognosis and death in patients. Serca2a is a target of interest in gene therapy for MI-induced heart failure via the regulation of intracellular calcium homeostasis and, subsequently, enhancing myocardial contractility. A recent study also reported that Serca2a ameliorates pulmonary fibrosis by blocking nuclear factor kB (NF-kB)/interleukin-6 (IL-6)-induced (SMAD)/TGF-β signaling activation, while the effect in MI-induced myocardial fibrosis remains to be addressed. Here, we loaded Serca2a plasmids into type 1 collagen-targeting nanoparticles to synthesize the GKWHCTTKFPHHYCLY-Serca2a-Liposome (GSL-NPs) for targeted treatment of myocardial infarction. We showed that GSL-NPs were effectively targeted in the scar area in MI-induced mice within tail-vein delivery for 48 h. Treatment with GSL-NPs improved cardiac functions and shrank fibrotic scars after MI in mice by up-regulating Serca2a. In cardiac fibroblasts, GSL-NPs alleviated hypoxia-induced fibrotic progression partly by inhibiting NF-kB activation. Furthermore, treatment with GSL-NPs protected cardiomyocyte calcium homeostasis and enhanced myocardial contractility during hypoxia. Together, we demonstrate that type I collagen-targeted liposome delivery of Serca2a may benefit patients with myocardial infarction by inhibiting fibrotic scarring as well as modulation of calcium homeostasis.

Management strategies and outcomes of thromboembolism prevention in atrial fibrillation co-existing with immune thrombocytopenia: A review of evidence

This review aimed to assess bleeding risks and explore management options in atrial fibrillation (AF) patients with immune thrombocytopenia (ITP), aiming to formulate an optimal therapeutic approach for improved patient prognosis. Employing MeSH terms, a comprehensive search strategy identified articles on bleeding risks and management guidelines in AF combined with ITP. Original research papers were included, while animal studies, reviews, and non-English articles were excluded. From four databases, 1891 articles were initially retrieved, resulting in 10 relevant full-text articles. Eight studies investigated the effectiveness of anticoagulants in managing concurrent AF and ITP, demonstrating reduced bleeding risk and promising outcomes. Two papers explored surgical interventions, particularly left atrial appendage closure, suggesting its safety for AF management in patients with primary hemostatic disorders, including thrombocytopenia. While the pathophysiological mechanisms of AF and ITP remain unclear, anticoagulation regimens exhibited promising reductions in bleeding risks. Larger studies are warranted to enhance understanding and investigate optimal treatments for AF and ITP.

In-hospital initiation of sodium-glucose cotransporter-2 inhibitors in patients with heart failure and reduced ejection fraction: 90-day prescription patterns and clinical implications

INTRODUCTION

Safety and early clinical benefit make sodium-glucose cotransporter-2 inhibitor (SGLT2-i) therapy suitable for in-hospital initiation in patients with heart failure and reduced ejection fraction (HFrEF). Despite randomized controlled trials and guideline recommendations, they are underused, and clinical inertia may play a role.

OBJECTIVES PRIMARY

To assess the impact of initiating SGLT-2i at discharge on 90-day prescription rates in patients with HFrEF during hospitalization for acute heart failure (AHF). Secondary: To evaluate the presence of independent factors associated with prescription, and to explore clinical outcomes at 90 days.

METHODS

Retrospective analysis of a consecutive prospective single-center cohort. Adult patients hospitalized between January 2021 and September 2022 with a primary diagnosis of AHF and left ventricular ejection fraction (LVEF) <40% were included. The primary outcome was SGLT2-i prescription rate at 90 days, and the exploratory secondary endpoints was the composite of hospitalization or urgent visit for AHF or all-cause mortality at 90 days.

RESULTS

237 patients were included. Mean age was 76±11 years, and mean LVEF was 29±7%. In patients without contraindications, SGLT2 inhibitors (SGLT2-i) were prescribed during hospitalization in 52.3%. At 90 days, the SGLT2-i prescription rate was 94.2% in those with in-hospital initiation and 14.4% in those without. (p<0.001). Independent factor associated with inpatient prescription was lower LVEF, 0.83 (95% CI: 0.77-0.89) for each point. Patients with in-hospital SGLT2-i initiation showed a lower rate of the combined endpoint of all-cause death, HF rehospitalization, or unplanned HF visit at 90 days (44.4% versus 23.9%, p=0.005).

CONCLUSIONS

In-hospital initiation of SGLT-2-i was associated with significantly higher prescription rates and lower prevalence in the secondary combined endpoint at 90 days. This study reflects the presence of medical inertia, particularly in patients with higher LVEF, and highlights the hospitalization period as an optimal time to start SGLT2-i.

Association of life's essential 8 with risk of recurrent cardiovascular events among patients with coronary heart disease

AIMS

To examine the association of Life's Essential 8 (LE8) with the risk of recurrent cardiovascular events among patients with CHD.

METHODS

This prospective cohort study included 11,997 patients with CHD from the UK Biobank. The LE8 score was generated using five lifestyle factors (diet, body mass index, physical activity, smoking, and sleep) and three biological factors (blood lipids, blood glucose, and blood pressure). LE8 score ranged from 0 to 100 and was categorized into quartiles. Cox proportional hazards regression models were applied to estimate the hazard ratio (HR) and 95% CI (confidence interval).

RESULTS

During a median follow up of 12.5 years, we documented 3366 recurrent cardiovascular events, 1068 myocardial infarction, 1829 heart failure events, 703 strokes, and 934 cardiovascular deaths. The multivariable-adjusted HR (95% CI) for the highest versus the lowest quartile of LE8 score was 0.57 (0.50, 0.65) for recurrent cardiovascular events, 0.66 (0.52, 0.83) for myocardial infarction, 0.54 (0.45, 0.67) for heart failure, 0.50 (0.36, 0.68) for stroke, and 0.46 (0.37, 0.56) for cardiovascular death. Furthermore, the population attributable fraction of the lowest to the highest quartile of LE8 score were ranged from 16.2% to 32.5% for the various cardiovascular outcomes. In addition, biomarkers including renal function and inflammation collectively explained 47.6%-87.7% of the associations between the lifestyle factors and recurrent cardiovascular events.

CONCLUSIONS

Better cardiovascular health as measured by LE8 was associated with significantly lower risk of recurrent cardiovascular events among patients with CHD. Clinicians should prioritize educating patients with CHD on the importance of optimal cardiovascular health for secondary prevention. In addition, our findings indicated significant mediation effect of biomarkers involving of glycemic control, renal function, liver function, lipid profile, and systemic inflammation on the associations between overall lifestyle factors and recurrent cardiovascular events.

Prognostic value of novel atherogenic indices in patients with acute myocardial infarction with and without type 2 diabetes

AIMS

Atherogenic indices: Triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio, Atherogenic Index of Plasma (AIP), Atherogenic Coefficient (AC), Castelli's Risk Index I and II (CRI-I, CRI-II) are used in clinical studies as surrogates of major adverse cardiac and cerebrovascular events (MACCE). Risk prediction of MACCE in patients with acute myocardial infarction (AMI) has vital role in clinical practice. We aimed to assess prognostic value of these indices following AMI.

METHODS

We analyzed patients with AMI with and without T2DM and the prognostic values of atherogenic indices for in-hospital death and MACCE within 12 months after AMI.

RESULTS

Of 2461 patients, 152 in-hospital deaths (6.2 %) were reported (74 patients [7.4 %] with T2DM and 78 [5.3 %] without T2DM; p = 0.042). MACCE occurred in 22.7 % of patients (29.7 % with T2DM and 17.9 % without T2DM; p < 0.001). TG/HDL-C and AIP were higher in T2DM patients compared to those without T2DM (p < 0.001). Long-term MACCE was more prevalent in patients with T2DM (p < 0.001). The AUC-ROC for predicting in-hospital death based on TG/HDL-C and AIP was 0.57 (p = 0.002).

CONCLUSIONS

None of the atherogenic indices was an independent risk factor for in-hospital death or MACCE at 12-month follow-up in patients with AMI. AIP was an independent risk factor for death at 12-month follow-up.

Echocardiographic characterization of age- and sex-associated differences in cardiac function and morphometry in nonhuman primates

Aging per se is a major risk factor for cardiovascular diseases and is associated with progressive changes in cardiac structure and function. Rodent models are commonly used to study cardiac aging, but do not closely mirror differences as they occur in humans. Therefore, we performed a 2D echocardiographic study in non-human primates (NHP) to establish age- and sex-associated differences in cardiac function and morphometry in this animal model. M mode and 2D echocardiography and Doppler analyses were performed cross-sectionally in 38 healthy rhesus monkeys (20 females and 18 males), both young (age 7-12 years; n = 20) and old (age 19-30 years; n = 18). The diameters of the cardiac chambers did not differ significantly by age group, but males had larger left ventricular diameters (2.43 vs 2.06 cm in diastole and 1.91 vs 1.49 cm in systole, p = 0.0004 and p = 0.0001, respectively) and left atrial diameter (1.981 vs 1.732 cm; p = 0.0101). Left ventricular mass/body surface area did not vary significantly with age and sex. Ejection fraction did not differ by age and females presented a higher ejection fraction than males (54.0 vs 50.8%, p = 0.0237). Diastolic function, defined by early to late mitral peak flow velocity ratio (E/A), was significantly lower in old rhesus monkeys (2.31 vs 1.43, p = 0.0020) and was lower in females compared to males (1.595 vs 2.230, p = 0.0406). Right ventricular function, evaluated by measuring the Tricuspid Annular Plane Systolic Excursion, did not differ by age or sex, and Right Ventricular Free Wall Longitudinal Strain, did not differ with age but was lower in males than in females (-22.21 vs -17.95%, p = 0.0059). This is the first echocardiographic study to evaluate age- and sex-associated changes of cardiac morphometry and function in young and old NHP. The findings of this work will provide a reference to examine the effect of age and sex on cardiac diseases in NHP.

The role of biomarkers in the prognosis and risk stratification in heart failure: A systematic review

Acute heart failure (AHF) episodes are marked by high rates of morbidity and mortality during the episode and minimal advancements in its care. Multiple biomarker monitoring is now a crucial supplementary technique in the therapy of AHF. A scientific literature search was conducted by assessing and evaluating the most pertinent research that has been published, including original papers and review papers with the use of PubMed, Medline, and Cochrane databases. Established biomarkers like natriuretic peptides (BNP, NT-proBNP) and cardiac troponins play crucial roles in diagnostic and prognostic evaluation. Emerging biomarkers such as microRNAs, osteopontin, galectin-3, ST2, and GDF-15 show promise in enhancing risk stratification and predicting adverse outcomes in HF. However, while these biomarkers offer valuable insights, their clinical utility requires further validation and integration into practice. Continued research into novel biomarkers holds promise for early HF detection and risk assessment, potentially mitigating the global burden of HF. Understanding the nuances of biomarker utilization is crucial for their effective incorporation into clinical practice, ultimately improving HF management and patient care.

Fibrates and risk of congenital malformations: a nationwide cohort study in South Korea

PURPOSE

To examine the association between maternal prescriptions for fibrates and congenital malformations in live births.

METHODS

Nationwide retrospective cohort study was conducted using the data sourced from the Korean National Health Insurance database. A cohort of 756,877 completed pregnancies linked to live-born infants in 215,600 women with dyslipidemia between 2012 and 2021. The study compared data on congenital anomalies between pregnancies who were exposed to fibrates and those who were not exposed to fibrates in the first trimester. Odds ratios (OR) were calculated by a multivariable analyses using logistic regression models to adjust for potential confounders.

RESULTS

260 pregnancies (0.12%) were exposed to fibrates during the first trimester. The prevalence of malformations in exposed offspirng was 10.77%, not significantly different compared with 9.68% in offspring of women who were not prescribed fibrates during pregnancy in patients with dyslipidemia (OR 1.13; 95% CI 0.75-1.70).

CONCLUSION

This study implies that the use of fibrates during pregnancy may be safe, as it did not show any association with congenital anomalies. However, caution is warranted due to an elevated risk associated with prolonged exposure.

The U-shaped association between remnant cholesterol and risk of all-cause and cardiovascular deaths in diabetic adults: Findings from NHANES 1999-2018

BACKGROUND AND AIMS

We aimed to explore the association between remnant cholesterol (RC) level and risks of all-cause and cardiovascular deaths among American diabetic adults.

METHODS AND RESULTS

The data of 4,095 diabetic participants from the National Health and Nutrition Examination Survey (1999-2018) were included for analysis. Deaths were ascertained till December 31, 2019. RC level associated with death was assessed on a continuous scale with restricted cubic splines and by pre-defined quartile groups with Cox regression analysis. After a median follow-up of 6.9 years, 1,060 all-cause and 289 cardiovascular deaths occurred. Association between RC and death was U-shaped, and RC level correlated with the lowest risks of both all-cause and cardiovascular deaths was 0.85 mmol/L. After adjusting for confounders, compared with Quartile 3 (0.66-0.93 mmol/L), hazard ratios for all-cause deaths were 1.43 (95%CI 1.18-1.72, P = 0.0002) in Quartile 1 (≤0.47 mmol/L), 1.20 (95%CI 1.00-1.44, P = 0.05) in Quartile 2 (0.47-0.66 mmol/L), and 1.25 (95%CI 1.05-1.49, P = 0.02) in Quartile 4 (>0.93 mmol/L). Higher risk was also observed for cardiovascular deaths in Quartile 1 (HR 1.66, 95%CI 1.15-2.41, P = 0.007), Quartile 2 (HR 1.39, 95%CI 0.97-2.00, P = 0.08), and Quartile 4 (HR 1.54, 95% CI 1.08-2.19, P = 0.02), as compared with Quartile 3.

CONCLUSION

In US adults with diabetes, low and high levels of RC were associated with increased risks of all-cause and cardiovascular deaths, and the lowest risk was observed at RC level of 0.85 mmol/L. These findings suggested that maintaining appropriate RC level may help reduce risk of death in diabetic patients.

DCRM 2.0: Multispecialty practice recommendations for the management of diabetes, cardiorenal, and metabolic diseases

The spectrum of cardiorenal and metabolic diseases comprises many disorders, including obesity, type 2 diabetes (T2D), chronic kidney disease (CKD), atherosclerotic cardiovascular disease (ASCVD), heart failure (HF), dyslipidemias, hypertension, and associated comorbidities such as pulmonary diseases and metabolism dysfunction-associated steatotic liver disease and metabolism dysfunction-associated steatohepatitis (MASLD and MASH, respectively, formerly known as nonalcoholic fatty liver disease and nonalcoholic steatohepatitis [NAFLD and NASH]). Because cardiorenal and metabolic diseases share pathophysiologic pathways, two or more are often present in the same individual. Findings from recent outcome trials have demonstrated benefits of various treatments across a range of conditions, suggesting a need for practice recommendations that will guide clinicians to better manage complex conditions involving diabetes, cardiorenal, and/or metabolic (DCRM) diseases. To meet this need, we formed an international volunteer task force comprising leading cardiologists, nephrologists, endocrinologists, and primary care physicians to develop the DCRM 2.0 Practice Recommendations, an updated and expanded revision of a previously published multispecialty consensus on the comprehensive management of persons living with DCRM. The recommendations are presented as 22 separate graphics covering the essentials of management to improve general health, control cardiorenal risk factors, and manage cardiorenal and metabolic comorbidities, leading to improved patient outcomes.

A High De Ritis Ratio Predicts Poor Myocardial Reperfusion in Patients With ST-Segment Elevation Myocardial Infarction

Successful reperfusion of myocardial tissue is the goal of primary percutaneous coronary intervention (pPCI) in patients with ST-segment elevation myocardial infarction (STEMI). We aimed to investigate the association between the De Ritis ratio (AST/ALT) and myocardial reperfusion in patients with STEMI who underwent pPCI. We retrospectively investigated 1236 consecutive patients who were hospitalized for STEMI and underwent pPCI. ST-segment resolution (STR) was defined as the return of the deviated ST-segment to baseline; poor myocardial reperfusion was defined as <70% STR. Patients were divided into 2 groups according to the median De Ritis ratio (.921); 618 patients (50%) were assigned to the De Ritis low group while 618 patients (50%) were assigned to the De Ritis high group. Stent size, neutrophil-to lymphocyte ratio (NLR), and the De Ritis ratio found to be associated with poor myocardial reperfusion (Odds ratio (OR) 1.45, 95% CI 1.07-1.98, P = .01, OR 1.22, 95% CI 1.01-1.48, P = .03 and OR 10.9, 95% CI 7.9-15, P < .001, respectively). A high De Ritis ratio was associated with poor myocardial reperfusion in STEMI patients who underwent pPCI. As an easily obtainable test in clinical practice, the De Ritis ratio may help identify patients at major risk for impaired myocardial perfusion.

Time-course atherogenic blood lipid response to statin discontinuation in dyslipidemic adults

BACKGROUND AND AIMS

Half of dyslipidemic patients sometimes discontinue statin medication. It is unclear if blood atherogenic risk increases right after statin discontinuation or if there is a lingering protective effect. We sought to determine if a legacy effect prevented blood lipid increases during the first stages of statin cessation.

METHODS AND RESULTS

Atherogenic blood lipid profile was measured in 10 overweight (BMI 31 ± 3 kg m-2) middle-aged males (62 ± 7 years old), statin users, while fasted and postprandially. Trials were conducted before (i.e., Day 0) and after 4, 7, 15, and 30 days of statin withdrawal and 20 days after statins reloading (Day 50). Four days after statin discontinuation, blood fasting LDL-c, total cholesterol (CHOL), and triglyceride (TG) concentrations increased by 30%, 18%, and 17%, respectively (P < 0.05). The increases in LDL-c, CHOL, and TG peaked after 7-15 days at 79%, 48%, and 34% of basal levels (P < 0.001), respectively. There were no significant correlations between the increases in blood lipids and the dose or years under statin treatment (P = 0.156-0.575). Twenty days after resuming statins, blood LDL-c (2.79 ± 1.06 vs 2.20 ± 0.50 mmol L-1; P = 0.568), CHOL (4.85 ± 1.41 vs 4.25 ± 0.83 mmol L-1; P = 0.747), and TG (1.47 ± 0.60 vs 1.50 ± 0.68 mmol L-1; P = 0.782), returned to basal levels.

CONCLUSIONS

Our data does not support a statin lingering/legacy effect in blood lipids since they dangerously increased after only 4 days of statin withdrawal in every patient, regardless of dose and years under treatment. Reloading statins restored blood lipids, evidencing a reproducible biological effect at the whole-body level.

Platelet-to-neutrophil ratio predicts hemorrhagic transformation and unfavorable outcomes in acute ischemic stroke with intravenous thrombolysis

BACKGROUND

Acute ischemic stroke (AIS) retains a notable stance in global disease burden, with thrombolysis via recombinant tissue plasminogen activator (rtPA) serving as a viable management approach, albeit with variable outcomes and the potential for complications like hemorrhagic transformation (HT). The platelet-to-neutrophil ratio (P/NR) has been considered for its potential prognostic value in AIS, yet its capacity to predict outcomes following rtPA administration demands further exploration.

AIM

To elucidate the prognostic utility of P/NR in predicting HT and clinical outcomes following intravenous rtPA administration in AIS patients.

METHODS

Data from 418 AIS patients treated with intravenous rtPA at Thammasat University Hospital from January 2018 to June 2021 were retrospectively analyzed. The relationship between P/NR and clinical outcomes [early neurological deterioration (E-ND), HT, delayed ND (D-ND), and 3-mo outcomes] was scrutinized.

RESULTS

Notable variables, such as age, diabetes, and stroke history, exhibited statistical disparities when comparing patients with and without E-ND, HT, D-ND, and 3-mo outcomes. P/NR prognostication revealed an optimal cutoff of 43.4 with a 60.3% sensitivity and a 52.5% specificity for 90-d outcomes. P/NR prognostic accuracy was statistically significant for 90-d outcomes [area under the curve (AUC) = 0.562], D-ND (AUC = 0.584), and HT (AUC = 0.607).

CONCLUSION

P/NR demonstrated an association with adverse 3-mo clinical outcomes, HT, and D-ND in AIS patients post-rtPA administration, indicating its potential as a predictive tool for complications and prognoses. This infers that a diminished P/NR may serve as a novel prognostic indicator, assisting clinicians in identifying AIS patients at elevated risk for unfavorable outcomes following rtPA therapy.

Long-Term Risk of Cardiovascular Death in Patients With Mildly Reduced Ejection Fraction After Acute Myocardial Infarction: A Multicenter, Prospective Registry Study

BACKGROUND

The prognostic implication of mildly reduced ejection fraction (mrEF) after acute myocardial infarction has not been clearly demonstrated. We investigated the long-term risk of cardiovascular death and its predictors in patients with mrEF following acute myocardial infarction.

METHODS AND RESULTS

A total of 18 668 patients who presented with acute myocardial infarction were included in 2 prospective, multicenter registries. The incidence of adverse cardiovascular events according to the left ventricular ejection fraction (EF) strata at index admission were evaluated. A score system consisting of clinical variables were developed to predict long-term cardiovascular death in the mrEF group. There were 2548 patients with reduced EF (EF ≤40%), 4266 patients with mrEF (EF 41%-49%), and 11 854 patients with preserved EF (EF ≥50%). During a median follow-up period of 37.9 months, the cardiovascular death rate was 22.3% in the reduced EF group, 10.3% in the mrEF group, and 7.3% in the preserved EF group (P<0.001). In the mrEF group, age>65 years, hypertension, stroke, severe renal insufficiency, and Killip class ≥3 were independent predictors for cardiovascular death. Presence of >2 predictors best discriminated the high-risk patients for cardiovascular death with an area under the curve of 0.746. Incidence of cardiovascular death in the high-risk mrEF group was comparable with the rEF group, while it was lower in the low-risk mrEF group than in the pEF group.

CONCLUSIONS

Patients with mrEF after acute myocardial infarction had a modest risk of cardiovascular death. Clinical predictors could help discriminate a high-risk subpopulation with cardiovascular death risks comparable with those in the reduced EF group.

SGLT2 Inhibitors vs GLP-1 Receptor Agonists and Clinical Outcomes in Patients With Diabetes With/Without Atrial Fibrillation

CONTEXT

The coexistence of diabetes mellitus and atrial fibrillation (AF) is associated with substantial risks of adverse cardiovascular events.

OBJECTIVE

The relevant outcomes associated with the use of a sodium-glucose cotransporter-2 inhibitor (SGLT2i) vs glucagon-like peptide-1 receptor agonists (GLP-1RAs) among patients with type 2 diabetes (T2D) with/without concomitant AF remain unknown.

METHODS

In this nationwide retrospective cohort study from the Taiwan National Health Insurance Research Database, there were 344 392 and 31 351 patients with T2D without AF, and 11 462 and 816 T2D patients with AF treated with SGLT2is and GLP-1RAs, respectively, from May 1, 2016, to December 31, 2019. Patients were followed from the drug index date until the occurrence of study events, discontinuation of the index drug, or the end of the study period (December 31, 2020), whichever occurred first. We used propensity score-stabilized weight to balance covariates across the 2 medication groups.

RESULTS

The incidence rate of all study outcomes in patients with concomitant AF was much higher than in those without concomitant AF. For the AF cohort, SGLT2i vs GLP-1RA was associated with a lower risk of hospitalization for heart failure (HF) (2.32 vs 4.74 events per 100 person-years; hazard ratio [HR] 0.48, 95% CI 0.36-0.66), with no benefit seen for the non-AF cohort (P for homogeneity < .01). SGLT2i vs GLP-1RA was associated with a lower risk of composite kidney outcomes both in the AF (0.38 vs 0.79 events per 100 person-years; HR 0.47; 95% CI 0.23-0.96) and the non-AF cohorts (0.09 vs 0.18 events per 100 person-years; HR 0.53; 95% CI 0.43-0.64). There were no significant differences in the risk of major adverse cardiovascular events and all-cause mortality in those who received SGLT2i compared with GLP-1RA for the AF or non-AF cohorts.

CONCLUSION

Considering the high risk of developing HF and/or high prevalence of concomitant HF in patients with concomitant diabetes and AF, whether SGLT2is should be the preferred treatment to GLP-1RAs for such a high-risk population requires further investigation.

One-Month Dual Antiplatelet Therapy Reduces Major Bleeding Compared With Longer-Term Treatment Without Excess Stent Thrombosis: A Systematic Review and Meta-Analysis of Randomized Clinical Trials

Dual antiplatelet therapy (DAPT) remains the gold standard in patients who underwent percutaneous coronary intervention (PCI). This meta-analysis aims to evaluate the clinical safety of 1-month DAPT followed by aspirin or a P2Y12 receptor inhibitor after PCI with drug-eluting stents (DES). We searched PubMed, MEDLINE, Embase, Scopus, Google Scholar, Cochrane Central Registry, and ClinicalTrials.gov databases and identified 5 randomized controlled trials with 29,831 patients who underwent PCI with DES and compared 1-month versus >1-month DAPT. The primary end point was major bleeding, and the co-primary end point was stent thrombosis. The secondary end point included all-cause mortality, cardiovascular death, myocardial infarction, stroke, and major adverse cardiovascular or cerebrovascular events. Compared with >1-month DAPT, the 1-month DAPT was associated with a lower rate of major bleeding (odds ratio [OR] 0.66, 95% confidence interval [CI] 0.45 to 0.97, p = 0.03, I2 = 71%), whereas stent thrombosis had a similar rate in both study groups (OR 1.08, 95% CI 0.81 to 1.44, p = 0.60, I2 = 0.0%). The study groups had similar risks for all-cause mortality (OR 0.89, 95% CI 0.77 to 1.04, p = 0.14, I2 = 0.0%), cardiovascular death (OR 0.84, 95% CI 0.59 to 1.19, p = 0.32, I2 = 0.0%), myocardial infarction (OR 1.04, 95% CI 0.89 to 1.21, p = 0.62, I2 = 0.0%), and stroke (OR 0.82, 95% CI 0.64 to 1.05, p = 0.11, I2 = 6%). The risk of major adverse cardiovascular or cerebrovascular events was lower (OR 0.86, 95% CI 0.76 to 0.97, p = 0.02, I2 = 25%) in the 1-month DAPT compared with >1-month DAPT. In conclusion, in patients who underwent PCI with DES, 1-month DAPT followed by aspirin or a P2Y12 receptor inhibitor reduced major bleeding with no risk of increased thrombotic risk compared with longer-term DAPT.

Angiography-versus wire-based microvascular resistance index to detect coronary microvascular obstruction associated with ST-segment elevation myocardial infarction

BACKGROUND

Microvascular obstruction (MVO) measured by cardiac magnetic resonance (CMR) after ST-segment elevation myocardial infarction (STEMI) has important prognostic implications. While invasive index of microvascular resistance (IMR) have been shown to predict the occurrence and extent of MVO, the role of the angiography-based microvascular resistance (Angio-IMR) for this purpose remains unknown. The present study aims to perform a head-to-head comparison of wire-based and angiography-derived microcirculatory resistance (IMR and Angio-IMR, respectively) for the detection of MVO.

METHODS

Patients with a first STEMI and multivessel disease underwent CMR for detection of MVO, and angio-IMR and IMR measurements during PPCI and at 30 day follow up, both in STEMI culprit and non-culprit vessels.

RESULTS

58 patients were included (mean age 60.7 ± 9.9 years, 82% male). At the time of PPCI, angio-IMR and IMR exhibited significant correlation (r = 0.70, P < 0.001), and agreement (coefficient of agreement 0.58). Both indices showed good predictive value of MVO [Angio IMR: AUC 0.79 (95% CI: 0.667-0.928); IMR: AUC 0.70 (95% CI: 0.539-0.853); p = 0.15]. Angio-IMR 40 U and IMR 34 U were identified as best cut-offs for prediction of MVO. In non-culprit vessels, angio-IMR and IMR also correlated well (rho = 0.59, p < 0.001), with overall lower mean values compared to culprit vessels (Angio-IMR: 36 vs. 23; IMR: 39 vs. 22, p < 0.001 for both comparisons).

CONCLUSION

Angio-IMR constitutes a valid alternative to wire-based IMR in predicting MVO in STEMI. Angio-IMR and IMR show a good correlation in the acute and subacute STEMI phases, both in culprit and non-culprit vessels.

Real-World Risk of Gastrointestinal Bleeding for Direct Oral Anticoagulants and Warfarin Users: A Distributed Network Analysis Using a Common Data Model

Background/Aims

Early studies on direct oral anticoagulants (DOACs) reported a higher risk of gastrointestinal bleeding (GIB) compared with warfarin; however, recent studies have reported a reduced risk. Therefore, this study was designed to evaluate the risk of GIB in users of DOAC and warfarin.

Methods

Using a common data model, we investigated the comparative risk of GIB in subjects from eight hospitals who were newly prescribed DOACs or warfarin. We excluded subjects who had a prior history of GIB or had been prescribed both medications. After propensity score matching, we analyzed 3,347 matched pairs of new DOAC and new warfarin users.

Results

The risk of GIB in new DOAC users was comparable to that in new warfarin users (hazard ratio [HR], 0.95; 95% confidence interval [CI], 0.65 to 1.40; p=0.808). New DOAC users had a similar risk of GIB to new warfarin users among older patients >65 years (HR, 1.00; 95% CI, 0.69 to 1.52; p=0.997) and in older patients >75 years (HR, 1.21; 95% CI, 0.68 to 2.10; p=0.509). In addition, the risk of GIB was not significantly different between two groups according to sex. We also found that the risk of GIB in DOAC users was 26% lower in edoxaban or apixaban subgroups compared to rivaroxaban or dabigatran subgroups (HR, 0.74; 95% CI, 0.69 to 1.00; p=0.049).

Conclusions

In real-world practice, the risk of GIB in new DOAC users is comparable to that in new warfarin users. In DOAC users, the risk of GIB was lower in edoxaban or apixaban subgroups than rivaroxaban or dabigatran subgroups.

Self-care adherence and associated factors among hypertensive patients at Guraghe Zone, 2023

Background

Hypertension is the primary cause of cardiovascular disease and early mortality. Self-care is important for the prevention of hypertensive-related complications, and it was found to be necessary to determine the self-care adherence of hypertensive patients in Guraghe Zone, as there are limited findings in this area. The other reason for conducting this study was that there are certain variables related to self-care that have not been well studied, such as BMI, the number of antihypertensive medications, and the duration of antihypertensive drugs the patients are taking.

Objective

To assess self-care adherence and associated factors among hypertensive patients at Guraghe zone public hospitals.

Methods and materials

A multi-center institution-based cross-sectional study was conducted at selected Guraghe zone hospitals from May 20 to June 20, 2023. A systematic random sampling method was employed to select 370 participants. Hypertension self-care Activity Level Scale Effects (H-SCALE) was used to measure the self-care status. A binary logistic regression model was applied, and variables with a p-value <0.05 with a 95 % CI in the multivariable analysis were considered significant.

Results

The study evaluated the self-care adherence of 370 patients, and 50.8 % of patients had good self-care adherence. Normal BMI (AOR = 2.049, 95 % CI: 1.041, 4.033), starting antihypertensive in <5 years (AOR = 2.530, 95 % CI: 1.462, 4.381), patients taking three or more antihypertensive (AOR = 4.534, 95 % CI: 2.005, 10.252), absence of comorbidity (AOR = 1.758, 95 % CI: 1.030, 3.003), and strong social support (AOR = 3.842, 95 % CI: 1.994, 7.402) were significantly associated with good self-care.

Conclusion

and recommendation: Nearly half of patients with hypertension had good self-care adherence. BMI, antihypertensive duration, number of antihypertensive, comorbidity, and social support were variables that showed significant association with self-care adherence. Patients need to implement the lifestyle recommendations in addition to regular follow-up to prevent complications. Health-care facilities need to provide health education on the proper implementation of self-care recommendations.

Outcomes of complete removal versus conservative therapy in cardiac implantable electronic device infections - A systematic review and Meta-analysis

BACKGROUND

Complete removal of cardiac implantable electronic devices (CIEDs) is recommended in patients with CIED infections, including both systemic and localized pocket infection. The aim of the study was to provide an up-to-date and comprehensive assessment of evidence relating to the effect of complete CIED extraction in patients with a CIED infection.

METHODS

We performed a systematic review and meta-analysis of studies reporting short- and mid-term outcomes in patients who had a device infection or infective endocarditis (IE) and underwent complete removal of the cardiac device (generator and leads) compared to those who received conservative therapy (no removal, partial removal, local antibiotic infiltration or isolated antibiotic therapy). The primary outcome was reinfection/relapse. Secondary outcomes were short-term (30-day/in-hospital) and mid-term (mean follow-up: 43.0 months) mortality. Random effects model was performed.

RESULTS

Thirty-two studies met the criteria for inclusion in the final analysis. Patients with complete CIED extraction (n = 905) exhibited a lower rate of relapse/re-infection compared to patients (n = 195) with a conservative treatment approach (n = 195, OR 0.02, 95%CI 0.01-0.06, p < 0.0001, mean-follow-up: 16.1 months). Additionally, these patients displayed a lower short- (OR 0.40, 95%CI 0.23-0.69, p = 0.01) and mid-term (OR 0.52, 95%CI 0.34-0.78, p = 0.002) mortality.

CONCLUSIONS

The analysis indicates that patients with a CIED infection who undergo complete CIED extraction exhibit a lower rate of relapse/re-infection. Additionally, a lower short- and mid-term mortality is observed, although it is acknowledged that this outcome may be influenced by treatment allocation bias.
