Impact of Frailty on Heart Failure Prognosis: Is Sex Relevant?

PURPOSE OF REVIEW

Heart failure (HF) is one of the most frequent causes of hospital admission in elderly patients, especially in women, who present a high prevalence of geriatric syndromes like frailty. Studies have suggested that frailty and its impact may also differ between males and females. Understanding how frailty may differently affect HF patients depending on sex is therefore imperative for providing personalized care. The aim of this review is to summarize the role of sex in the prognostic impact of frailty in HF patients.

RECENT FINDINGS

Numerous studies have identified frailty as a significant predictor of all-cause mortality and hospital readmissions. A recent study of elderly HF out-patients demonstrated that while women had a higher prevalence of frailty, it was an independent predictor of mortality and readmission only in men. Moreover, another study revealed that physical frailty was associated with time to first clinical event among men but not among women. These results raise the question about why frailty affects differently HF prognosis in men and women. Women with HF present a higher prevalence of frailty, especially when it is considered as physical decline. Nevertheless, frailty affects differently HF prognosis in men and women. Women with HF present lower mortality than men and frailty is related with prognosis only in men. The different severity of HF between men and women and other hormonal, psychosocial, and clinical factors might be involved in this fact.

Prevalence of Sarcopenia in Chronic Heart Failure and Modulating Role of Chronic Kidney Disease

INTRODUCTION

Sarcopenia, heart failure (HF), and chronic kidney disease (CKD) are common among the older people. Our objective was to evaluate the frequency of sarcopenia, among community-dwelling older adults with HF, possible causative factors, and the additive factor of CKD.

METHODS

A cross-sectional analysis of 1,420 older people living in the community was carried out. Participants (aged 75 years and more) came from a European multicenter prospective cohort (SCOPE study). Global geriatric assessment including short physical performance battery, handgrip strength test, and bioelectrical impedance analysis was performed. Previous known HF was defined as physician-diagnosed HF registered in the patient's medical record or the use of HF-related medications, regardless of left ventricular ejection fraction (LVEF). Sarcopenia was defined by the updated criteria of the European Working Group on Sarcopenia in Older People (EWGSOP2). Estimated glomerular filtration rate was calculated using Berlin Initiative Study (BIS) to define the stages of CKD. Two-year mortality was also collected.

RESULTS

A total of 226 (15.9%) participants had a prior chronic HF diagnosis, with a median age of 80.0 (5.0), and 123 (54.4%) were women. Using EWGSOP2 definition, 11.5% HF and 10.7% in non-HF participants met diagnostic criteria for sarcopenia. In multivariate analyses, only a lower body mass index (BMI) (odds ratios [OR], 0.82; 95% confidence interval [CI], 0.73-0.93) and lower short physical performance battery score (OR, 0.81; 95% CI, 0.69-0.96) were associated with sarcopenia. Patients with HF and sarcopenia have a similar all-cause mortality risk but higher 2-year cardiovascular mortality risk (p = 0.047).

DISCUSSION/CONCLUSION

One out of ten community-dwelling older adults with concurrent clinical stable chronic HF, without considering LVEF, have sarcopenia. Lower BMI and poor physical performance are associated with sarcopenia in this population, but not CKD.

Prognosis of acute heart failure in patients followed up in nursing homes in Spain: Results from the RICA registry

BACKGROUND

Patients with chronic diseases such as heart failure (HF) are at risk of hospital admission. We evaluated the impact of living in nursing homes (NH) on readmissions and all-cause mortality of HF patients during a one-year follow up.

METHODS

An observational and multicenter study from the Spanish National Registry of Heart Failure (RICA) was performed. We compared clinical and prognostic characteristics between both groups. Bivariate analyses were performed using Student's t-test and Tukey's method and a Kaplan-Meier survival at one-year follow up. A multivariate proportional hazards analysis of [Cox] regression by the conditional backward method was conducted for the variables being statistically significant related to the probability of death in the univariate.

RESULTS

There were 5644 patients included, 462 (8.2%) of whom were nursing home residents. There were 52.7% women and mean age was 79.7±8.8 years. NH residents had lower Barthel (74.07), Charlson (3.27), and Pfeiffer index (2.2), p<0.001). Mean pro-BNP was 6686pg/ml without statistical significance differences between groups. After 1-year follow-up, crude analysis showed no differences in readmissions 74.7% vs. 72.3%, p=0.292, or mortality 63.9% vs. 61.1%, p=0.239 between groups. However, after controlling for confounding variables, NH residents had a higher 1-year all-cause mortality (HR 1.153; 95% CI 1.011-1.317; p=0.034). Kaplan-Meier analysis showed worse survival in nursing home residents (log-rank of 7.12, p=0.008).

CONCLUSIONS

Nursing home residents with heart failure showed higher one-year mortality which could be due to worse functional status, higher comorbidity, and cognitive deterioration.

Consensus on basic conduct during the hospital admission of patients with acute heart failure

Acute heart failure (AHF) is a highly prevalent clinical entity in individuals older than 45years in Spain. AHF is associated with significant morbidity and mortality and is the leading cause of hospitalisation for individuals older than 65years in Spain, a quarter of whom die within 1year of the hospitalisation. In recent years, there has been an upwards trend in hospitalisations for AHF, which increased 76.7% from 2003 to 2013. Readmissions at 30days for AHF have also increased (from 17.6% to 22.1%), at a relative mean rate of 1.36% per year, with the consequent increase in the use of resources and the economic burden for the healthcare system. The aim of this document (developed by the Heart Failure and Atrial Fibrillation Group of the Spanish Society of Internal Medicine) is to guide specialists on the most important aspects of treatment and follow-up for patients with AHF during hospitalisation and the subsequent follow-up. The main recommendations listed in this document are as follows: (1)At admission, perform a comprehensive assessment, considering the patient's standard treatment and comorbidities, given that these determine the disease prognosis to a considerable measure. (2)During the first few hours of hospital care, decongestive treatment is a priority, and a staged diuretic therapeutic approach based on the patient's response is recommended. (3)To manage patients in the stable phase, consider starting and/or adjusting evidence-based drug treatment (e.g., sacubitril/valsartan or angiotensin-converting enzyme inhibitors/angiotensinII receptor blockers, beta blockers and aldosterone antagonists). (4)At hospital discharge, use a checklist to optimise the patient's management and identify the most efficient options for maintaining continuity of care after discharge.

Differential characteristics of acute heart failure in very elderly patients: the prospective RICA study

INTRODUCTION

Acute heart failure (AHF) is a frequent epidemic in geriatrics. The main aim of this study was to evaluate the clinical and prognostic differences of very elderly patients with AHF compared to the rest, and evaluate the factors associated with 90-day mortality.

METHODS

We analyzed 3828 patients hospitalized for AHF with an age of ≥ 70 years. The population was divided into three groups: 70-79, 80-89 and ≥ 90 years old (nonagenarians). The baseline characteristics of patients nonagenarians were compared with the rest. In the group of nonagenarians, their clinical characteristics were analyzed according to the left ventricular ejection fraction (LVEF) and the factors associated with mortality at 90 days of follow-up.

RESULTS

Nonagenarians showed higher comorbidity and cognitive deterioration, worse basal functional status, and preserved LVEF. Alternatively, they presented a lower rate of diabetes mellitus, lower incidence of de novo AHF, and lower prescription of angiotensin-converting-enzyme inhibitors, aldosterone blockers, anticoagulants, and statins at hospital discharge. Of the total, 334 patients (9.3%) had died by 90 days. The 90-day mortality rate was highest in nonagenarians (7.1% vs 9.8% vs 17%; p = 0.001). Multivariate analysis showed that renal failure, New York Heart Association (NYHA) functional classifications of III-IV, and a more advanced functional deterioration at baseline are predictors of mortality within 90 days.

CONCLUSIONS

The AHF in patients nonagenarians has a different clinical profile compared to younger patients and a higher mortality. In this subgroup of patients having a worse baseline functional status, higher NYHA classification (III-IV), and renal failure are predictors of 90-day mortality.

Usefulness of systolic blood pressure combined with heart rate measured on admission to identify 1-year all-cause mortality risk in elderly patients firstly hospitalized due to acute heart failure

BACKGROUND

Systolic blood pressure (SBP) and heart rate (HR) are well-known prognostic factors in heart failure (HF).

AIMS

Our objective was to assess the value of the combination of admission SBP and HR to estimate 1-year mortality risks in elderly patients admitted due to a first episode of acute HF (AHF).

METHODS

During a 36-month period, we retrospectively reviewed 901 consecutive patients aged ≥ 75 admitted because of a first episode of AHF. According to admission SBP-HR combinations, three groups were defined: "low-risk" (HR < 70 bpm and SBP ≥ 140 mmHg), "moderate-risk" (HR < 70 bpm and SBP < 140 mmHg or HR ≥ 70 bmp and SBP ≥ 120 mmHg), and "high-risk" (HR ≥ 70 bpm and SBP < 120 mmHg). We analyzed all-cause mortality using Cox mortality analysis.

RESULTS

One-year mortality ranged from 16.5% for patients in the low-risk group to 50% for those in the high-risk group (p < 0.0001). Multivariate Cox regression for 1-year mortality showed hazard risk (HzR) ratios, compared to that (HzR 1) of the low-risk reference group, of 1.759 (95% CI 1.035-2.988, p = 0.037) for moderate-risk, and 3.171 (95% CI 1.799-5.589, p = 0.0001) for high-risk group. Prior use of a high number of chronic therapies (HzR 1.045), lower admission diastolic BP (HzR 0.986) and higher admission serum potassium values (HzR 1.534) were also significantly associated with mortality.

CONCLUSION

In elderly population firstly hospitalized due to AHF, the simple combined admission measurement of SBP and HR predicts higher risk for 1-year all-cause mortality.

Impact of intestinal microbiota in patients with heart failure: A systematic review

Heart failure (HF) is a chronic disease with significant morbidity and mortality. Substantial haemodynamic changes such as hypoperfusion and intestinal congestion can alter the composition of the intestinal microbiota in patients with HF. The aim of this systematic review is to evaluate the influence of bowel function in patients with HF and the possible role of the intestinal microbiota in the development and evolution of the latter. Eleven studies were included in the review. These studies seem to confirm that HF patients present with substantial abnormalities in the composition of their intestinal microbiota. Trimethylamine N-oxide is identified as a key mediator between the alterations in the intestinal microbiota and HF and correlates with worse prognosis in HF patients. In conclusion, patients with HF present with frequent abnormalities in the characteristics of their intestinal microbiota, which may play a role in the prognosis of the disease.

Effects of high-quality nursing care on psychological outcomes in patients with chronic heart failure

BACKGROUND

This study will assess the effects of high quality nursing care (HQNC) on psychological outcomes (PCO) in patients with chronic heart failure (CHF).

METHODS

We will carry out a through search in 7 databases: PUBMED, EMBASE, Cochrane Library, Web of Science, Chinese Biomedical Literature Database, WANGFANG, and China National Knowledge Infrastructure. Eligibility criteria will be randomized controlled trials on assessing effects of HQNC on PCO in patients with CHF. Cochrane risk of bias evaluation will be utilized for methodological quality.

RESULTS

This proposed study will summarize a rational synthesis of current evidence for HQNC on PCO in patients with CHF.

CONCLUSION

The results of this study will provide convinced evidence for judging the effects of HQNC on PCO in patients with CHF.

Heart failure and diabetes: The confrontation of two major epidemics of the 21st century

There is a bidirectional association between heart failure (HF) and type 2 diabetes mellitus (DM2), which has resulted in an exponential increase in the combination of the 2 diseases in a single patient. This combination is one of many common causes that lead to the pathophysiological pathways resulting in the deleterious effect of DM2 on HF. The inevitable clinical consequence is that, when faced with this situation, patients present worse symptoms and a poorer prognosis than patients with HF but without DM2. We should therefore consider how to treat DM2 in patients with HF and how to treat HF in patients with DM2. In this review, we highlight the latest published data on this issue.

Lower admission blood pressure as an independent predictor of 1-year mortality in elderly patients experiencing a first hospitalization for acute heart failure

BACKGROUND

Systolic blood pressure (SBP) is an acknowledged prognostic factor in patients with heart failure (HF). Admission SBP should be a risk factor for 1-year mortality even in elderly patients experiencing a first admission for HF, and this risk may persist in the oldest subset of patients.

DESIGN

Methods: We reviewed the medical records of 1031 patients aged 70 years or older admitted within a 3-year period for a first episode of acute heart failure (AHF). The cohort was divided according to admission SBP values in quartiles. We analyzed all-cause mortality as a function of these admission SBP quartiles.

RESULTS

Mean age was 82.2 ± 6 years; their mean admission SBP was 138.6 ± 25 mmHg. A statistically significant association was present between mortality at 30 (p < 0.0001), 90 (p < 0.0001), and 365 days (p < 0.0001) after hospital discharge and lower admission SBP quartiles. One-year mortality ranged from 14.7% for patients within the upper SBP quartile to 41.4% for those in the lowest quartile. The multivariate analysis confirmed this association (HR: 0.884; 95% CI: 0.615-0.76; p = 0.0001), which remained significant when admission SBP was evaluated as a continuous variable (HR: 0.980; 95% CI: 0.975-0.985; p = 0.0001). The association between SBP and 1-year mortality remained when the sample was divided into old (70-82 years) and "oldest-old" (>82 years) patients.

CONCLUSIONS

Lower SBP at admission is an independent predictor of midterm postdischarge mortality for elderly patients experiencing a first admission for AHF.

[Profile of heart failure according to the department of admission. Implications for multidisciplinary management]

INTRODUCTION

Population aging has led to notable changes in heart failure admissions. The aim of this study was to analyse the characteristics, comorbidity, management, and outcomes of this patient population in three hospital departments.

METHODS

An analysis was made of a prospective register that included all patients admitted due to heart failure in Internal Medicine, Cardiology, and Geriatrics over a period of 45 days.

RESULTS

Of a total of 235 patients, 124 (52.7%) were admitted to Internal Medicine, 83 (35.3%) to Cardiology, and 28 (11.9%) to Geriatrics. Mean age was 77.0±20.2 years (Cardiology 71.5±13.5; Internal Medicine 79.2±21.1; Geriatrics 89.9±5.1; p<.001). Preserved ejection fraction was found in 121 (51.5%) patients, and this rate was higher in Internal Medicine (62.5%) and Geriatrics (70.0%) than in Cardiology (31.3%), p<.001. Comorbidity was frequent, especially atrial fibrillation (126; 53.6%), renal disease (89; 37.8%), and chronic obstructive pulmonary disease (65; 27.6%). Infections were the most common decompensating trigger in Internal Medicine (56; 45.2%), and there was often no trigger in Cardiology (45; 54.2%) and Geriatrics (14; 50.0%), p<.0001. The use of renin-angiotensin system inhibitors, beta-blockers, and spironolactone in patients with systolic dysfunction was higher in Cardiology. During the 45 days follow-up, 23 patients (9.9%) were readmitted, which was more frequent in Internal Medicine than in Cardiology (odds ratio 3.0 [95% confidence interval: 1.1 - 8.6], p=.03), with no other significant comparisons.

CONCLUSIONS

Patients admitted due to decompensated heart failure are elderly and often have comorbidities. There are major differences between departments as regards age and clinical profile.
