Sex-Related Differences in Heart Failure Diagnosis

PURPOSE OF REVIEW

The literature on the importance of sex in heart failure diagnosis is scarce. This review aims to summarize current knowledge on sex differences regarding the diagnosis of heart failure.

RECENT FINDINGS

Comorbidities are frequent in patients with heart failure, and their prevalence differs between sexes; some differences in symptomatology and diagnostic imaging techniques were also found. Biomarkers also usually show differences between sexes but are not significant enough to establish sex-specific ranges. This article outlines current information related to sex differences in HF diagnosis. Research in this field remains to be done. Maintaining a high diagnostic suspicion, actively searching for the disease, and considering the sex is relevant for early diagnosis and better prognosis. In addition, more studies with equal representation are needed.

Characterizing Sex Differences in Physical Frailty Phenotypes in Heart Failure

BACKGROUND

Although women with heart failure (HF) are potentially more likely to be physically frail compared with men with HF, the underlying contributors to this sex difference are poorly understood. The purpose of this study was to characterize sex differences in physical frailty phenotypes in HF.

METHODS

We prospectively enrolled adults with class I-IV HF. Physical frailty was measured with the frailty phenotype criteria. Symptoms of dyspnea, sleep-related impairment, pain interference, depression, and anxiety were assessed. Body composition was measured using dual-energy x-ray absorptiometry. Simple comparative statistics and stepwise regression modeling were used.

RESULTS

The average age of the sample (n=115) was 63.6±15.7 years, 49% were women, and 73% had nonischemic cause. Forty-three percent of the sample was physically frail. Women had a 4.6 times greater odds of being physically frail compared with men, adjusting for covariates (odds ratio=4.63 [95% CI, 1.81-11.84], P=0.001). Both physically frail men and women were characterized by more type 2 diabetes, higher comorbidity burden, and worse dyspnea symptoms. Physically frail women had significantly worse symptoms compared with non-physically frail women but no difference in body composition characteristics. Physically frail men had significantly lower appendicular muscle mass, higher percent fat, lower hemoglobin, and more depressive symptoms compared with non-physically frail men.

CONCLUSIONS

Women are significantly more likely to be physically frail compared with men in HF. Physical frailty in both women and men is characterized by comorbidities and worse symptoms; physical frailty in men is characterized by worse physiological characteristics.

Prognostic value of ambulatory blood pressure values in elderly patients with heart failure. Results of the DICUMAP study

INTRODUCTION

Ambulatory blood pressure monitoring (ABPM) has demonstrated value in the prognostic assessment of hypertensive patients with heart failure (HF) with or without other cardiovascular diseases. The objective of this study was to evaluate whether ABPM can identify subjects with HF with a worse prognosis.

METHODS AND RESULTS

Prospective multicenter study that included clinically stable outpatients with HF. All patients underwent ABPM. A total of 154 patients from 17 centers were included. Their mean age was 76.8 years (± 8.3) and 55.2% were female. In total, 23.7% had HF with a reduced ejection fraction (HFrEF), 68.2% were in NYHA functional class II, and 19.5% were in NYHA functional class III. At one year of follow up, there were 13 (8.4%) deaths, of which 10 were attributed to HF. Twenty-nine patients required hospitalization, of which 19 were due to HF. The presence of a non-dipper BP pattern was associated with an increased risk for readmission or death at one year of follow-up (25% vs. 5%; p=.024). According to a Cox regression analysis, more advanced NYHA functional class (hazard ratio 3.51; 95% CI 1.70-7.26; p=.001; for NYHA class III vs. II) and a higher proportional nocturnal reduction in diastolic BP (hazard ratio 0.961; 95%CI 0.926-0.997; p=.032 per 1% diastolic BP reduction) were independently associated with death or readmission at one year.

CONCLUSION

In older patients with chronic HF, a non-dipper BP pattern measured by ABPM was associated with a higher risk of hospitalization and death due to HF.

The Female Sex Confers Different Prognosis in Heart Failure: Same Mortality but More Readmissions

Introduction: Heart failure (HF) is a major cause of morbimortality both in men and women. Differences between sex in etiopathogenesis, response to treatment, and quality of care have been found in patients with HF. Females are usually under-represented in clinical trials and there is no solid evidence demonstrating the influence of sex in the prognostic of chronic HF. The primary objective of this study was to analyse the differences in mortality and probability of hospital readmission between males and females with HF. The secondary objective was to compare mortality and probability of hospital readmission by ejection fraction (reduced vs. preserved). Methods: Patients with decompensated HF that were consecutively admitted to a Cardiology Service of a tertiary hospital for 4 years were recruited. De novo HF, death during hospitalization, programmed admissions and those patients with moderate left ventricular ejection fraction (LVEF) (40-50%) were discarded. Finally, 1,291 patients were included. Clinical profiles, clinical history, functional status, treatment at admission, first blood analysis performed, readmissions and mortality at follow-up were analyzed and compared. All patients underwent an echocardiographic study at admission. HF with reduced ejection fraction (HFrEF) was considered when left ventricular ejection fraction (LVEF) was <40%, whilst HF with preserved ejection fraction (HFpEF) was considered when LVEF was ≥50%. Results: 716 participants were male (55%). Basal characteristics showed differences in some outcomes. No differences were found in probability of survival among patients with decompensated HF by sex and ejection fraction (p = 0.25), whereas there was a clear tend to a major survival in females with HFrEF (p < 0.1). Females presented more readmissions when compared to males, independently from the LVEF (females = 33.5% vs. males = 26.8%; p = 0.009). Adjusted multivariate analysis showed no association between sex and mortality (HR = 0.97, IC 95% = 0.73-1.30, p = 0.86), although there was association between female sex and probability of readmission (OR = 1.37, IC 95% = 1.04-1.82, p = 0.02). Conclusions: Sex does not influence mid-term mortality in patients admitted for decompensated HF. Nevertheless, probability of readmission is higher in females independently from LVEF. Thus, it should be considered whether healthcare may be different depending on sex, and a more personalized and frequent care may be recommended in females.

Gender-related clinical and management differences in patients with chronic heart failure with reduced ejection fraction

AIM

Gender-related differences have been described in the clinical characteristics and management of patients with chronic heart failure with reduced ejection fraction (HFrEF). However, published data are conflictive in this regard.

METHODS

We investigated differences in clinical and management variables between male and female patients from the ATA study, a prospective, multicentre, observational study that included 1462 outpatients with chronic HFrEF between January and June 2019.

RESULTS

Study population was predominantly male (70.1%). In comparison to men, women with chronic HFrEF were older (66 ± 11 years vs 69 ± 12 years, P < .001), suffered more hospitalisations and presented more frequently with NYHA class III or IV symptoms. Ischaemic heart disease was more frequent in men, whereas anaemia, thyroid disease and depression were more frequent in women. No difference was seen between genders in the use rate of renin-angiotensin system inhibitors, beta-blockers, mineralocorticoid receptor antagonists, or ivabradine, or in the proportion of patients achieving target doses of these drugs. Regarding device therapies, men were more often treated with an implantable cardioverter-defibrillator (ICD) and women received more cardiac resynchronisation therapy.

CONCLUSION

In summary, although management seemed to be equivalent between genders, women tended to present with more symptoms, require hospitalisation more frequently and have different comorbidities than men. These results highlight the importance of gender-related differences in HFrEF and call for further research to clarify the causes of these disparities. Gender-specific recommendations should be included in future guidelines in HFrEF.

Cognitive impairment in patients hospitalized for congestive heart failure: data from the RICA Registry

The objective of this study is to determine the prevalence of cognitive impairment (CogI) in patients hospitalized for congestive heart failure, and the influence of CogI on mortality and hospital readmission. This is a multicenter cohort study of patients hospitalized for congestive heart failure enrolled in the RICA registry. The patients were divided into 3 groups according to their Short Portable Mental Status Questionnaire score: 0-3 errors (no CogI or mild CogI), 4-7 (moderate CogI) and 8-10 (severe CogI). A total of 3845 patients with a mean (SD) age of 79 (8.6) years were included; 2038 (53%) were women. A total of 550 (14%) patients had moderate CogI and 76 (2%) had severe CogI. Factors independently associated with severe CogI were age (OR 1.09, 95% CI 1.05-1.14 p < 0.001), male sex (OR 0.57, 95% CI 0.34-0.95, p = 0.031), heart rate (OR 1.01, 95% CI 1.00-1.02, p = 0.004), Charlson index (OR 1.16, 95% CI 1.06-1.27, p = 0.002), and history of stroke (OR 2.67, 95% CI 1.60-4.44, p < 0.001). Severe CogI was associated with higher mortality after one year (HR 3.05, 95% CI 2.25-4.14, p < 0.001). The composite variable of death/hospital readmission was higher in patients with CogI (log rank p < 0.001). Patients with heart failure and severe CogI are older and have a higher comorbidity burden, lower survival, and a higher rate of death or readmission at 1 year, compared to patients with no CogI.

Living with advanced heart failure: A qualitative study

Introduction

Information about how patients with advanced heart failure (HF) live and cope with their disease remains scarce. The objective of this study was to explore, from phenomenological and holistic perspectives, the experiences of patients suffering from advanced HF, attended at home in the primary care setting in 2018.

Materials and methods

Qualitative study conducted in 4 primary healthcare centers in Barcelona (Spain). Twelve in-depth interviews were conducted in advanced HF patients, aged over 65 and visited regularly at home. We developed a purposeful sampling, accounting for variability in gender, age, and socioeconomic level. Leventhal’s framework was used to analyze the interviews.

Results

Participants received insufficient and contradictory information about HF. They talked about their cognitive representation and claimed a better communication with healthcare professionals. Due to their advanced age, subjects considered their daily living limitations to be normal rather than as a consequence of HF. Gender differences in emotional representation were clearly observed. Women considered themselves the keystone of correct family “functioning” and thought that they were not useful if they could not correspond to gendered societal expectations. Cognitive coping strategies included specific diets, taking medication, and registering weight and blood pressure. Nevertheless, they perceived the locus of control as external and felt unable to manage HF progression. Their emotional coping strategies included some activities at home such as watching television and reading. Social support was perceived crucial to the whole process.

Conclusions

Locus of control in advanced HF was perceived as external. Healthcare professionals should adapt emotional health interventions in patients with advanced HF based on a gender perspective. Social support was found to be crucial in facing the disease. Patients reported poor communication with healthcare professionals.

Sex Differences in Comorbidity, Therapy, and Health Services' Use of Heart Failure in Spain: Evidence from Real-World Data

Heart failure (HF) is becoming increasingly prevalent and affects both men and women. However, women have traditionally been underrepresented in HF clinical trials. In this study, we aimed to analyze sex differences in the comorbidity, therapy, and health services’ use of HF patients. We conducted a cross-sectional study in Aragón (Spain) and described the characteristics of 17,516 patients with HF. Women were more frequent (57.4 vs. 42.6%, p < 0.001) and older (83 vs. 80 years, p < 0.001) than men, and presented a 33% lower risk of 1-year mortality (p < 0.001). Both sexes showed similar disease burdens, and 80% suffered six or more diseases. Some comorbidities were clearly sex-specific, such as arthritis, depression, and hypothyroidism in women, and arrhythmias, ischemic heart disease, and COPD in men. Men were more frequently anti-aggregated and anti-coagulated and received more angiotensin-converting-enzyme (ACE) inhibitors and beta-blockers, whereas women had more angiotensin II antagonists, antiinflammatories, antidepressants, and thyroid hormones dispensed. Men were admitted to specialists (79.0 vs. 70.6%, p < 0.001), hospital (47.0 vs. 38.1%, p < 0.001), and emergency services (57.6 vs. 52.7%, p < 0.001) more frequently than women. Our results highlight the need to conduct future studies to confirm the existence of these differences and of developing separate HF management guidelines for men and women that take into account their sex-specific comorbidity.

Differences in Epidemiology and Risk Factors for Atrial Fibrillation Between Women and Men

Atrial fibrillation (AF), the most common sustained cardiac arrhythmia, is one of the most frequent cardiovascular diseases among both women and men. Although age-adjusted AF incidence and prevalence is larger among men, women are older at the time of AF diagnosis and have larger risk for AF-associated adverse outcomes such as morality and stroke. Based on evidence from epidemiological studies, elevated body mass index seems to confer a higher risk of AF among men. However, evidence regarding sex differences in the association between diabetes mellitus, elevated blood pressure, and dysglycemia with AF remains conflicting. While men with AF have larger burden of coronary artery disease, women with AF tend to have a larger prevalence of heart failure and valvular heart disease. Recently, several women-specific risk factors including pregnancy and its complications and number of children have been associated with AF. Earlier age at menopause, despite being a strong marker of adverse cardiometabolic risk, does not seem to be associated with increased risk of AF. To reduce the AF burden in both genders, better understanding of the differences between women and men with regard to AF is central. Large-scale studies are needed to separately investigate and report on women and men. Besides observations from epidemiological and clinical studies, to improve our understanding of sexual dimorphism in AF, sufficiently large genome-wide association studies as well as well-powered Mendelian randomization studies are essential to shed light on the sex-specific nature of the associations of risk factors with AF.

Sex- and age-related differences in the management and outcomes of chronic heart failure: an analysis of patients from the ESC HFA EORP Heart Failure Long-Term Registry

AIMS

This study aimed to assess age- and sex-related differences in management and 1-year risk for all-cause mortality and hospitalization in chronic heart failure (HF) patients.

METHODS AND RESULTS

Of 16 354 patients included in the European Society of Cardiology Heart Failure Long-Term Registry, 9428 chronic HF patients were analysed [median age: 66 years; 28.5% women; mean left ventricular ejection fraction (LVEF) 37%]. Rates of use of guideline-directed medical therapy (GDMT) were high (angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, beta-blockers and mineralocorticoid receptor antagonists: 85.7%, 88.7% and 58.8%, respectively). Crude GDMT utilization rates were lower in women than in men (all differences: P ≤ 0.001), and GDMT use became lower with ageing in both sexes, at baseline and at 1-year follow-up. Sex was not an independent predictor of GDMT prescription; however, age >75 years was a significant predictor of GDMT underutilization. Rates of all-cause mortality were lower in women than in men (7.1% vs. 8.7%; P = 0.015), as were rates of all-cause hospitalization (21.9% vs. 27.3%; P < 0.001) and there were no differences in causes of death. All-cause mortality and all-cause hospitalization increased with greater age in both sexes. Sex was not an independent predictor of 1-year all-cause mortality (restricted to patients with LVEF ≤45%). Mortality risk was significantly lower in patients of younger age, compared to patients aged >75 years.

CONCLUSIONS

There was a decline in GDMT use with advanced age in both sexes. Sex was not an independent predictor of GDMT or adverse outcomes. However, age >75 years independently predicted lower GDMT use and higher all-cause mortality in patients with LVEF ≤45%.

Sex and Cardiovascular Involvement in Inflammatory Joint Diseases

The term inflammatory joint disease (IJD) encompasses a group of chronic conditions with predominant joint involvement. They share an increased risk of cardiovascular (CV) complications. However, the implication of the sex in the risk of CV disease in IJD has not been specifically addressed. The aim of this work is to assess the influence of sex on the clinical expression of CV manifestations associated to IJD. With this objective, an update of the current knowledge of the sex influence on CV disease in patients with IJD was conducted. A PubMed database search of the most relevant literature on this topic was performed mainly based on studies published in English over the last 10 years. Although most studies on IJD were not specifically designed to address sex differences regarding CV complications, it seems that men with rheumatoid arthritis (RA) are at higher risk of pericarditis, ischemic heart disease, heart failure (HF) with reduced ejection fraction (EF), and CV mortality than women with RA. In contrast, HF with preserved EF and diastolic dysfunction is more frequent in women with RA. Men with ankylosing spondylitis present more frequently disorders of the conduction system and aortic valvulopathy than women. A limited number of studies addressed CV differences according to sex in psoriatic arthritis. Although there are some differences according to sex in the clinical expression of CV complications in patients with IJD, much research is still needed to better identify the implication of sex in the risk of CV disease in these patients.

Gender Differences in Prognostic Markers of All-Cause Death in Patients with Acute Heart Failure: a Prospective 18-Month Follow-Up Study

Acute heart failure (AHF) is a life-threatening condition with poor prognosis. Gender differences have been increasingly recognized in diverse cardiovascular diseases. The present study aimed to evaluate gender-specific prognostic markers of all-cause death in AHF patients based on a prospective 18-month follow-up study. Data were collected from 419 patients with AHF hospitalization who were followed up for 18 months using all-cause death as primary endpoint. The mean age of all patients was 60.9 ± 15.7 years old, 277 were males, and 142 were females. Females had higher rate of valvular heart disease (37.3%) and atrial fibrillation (45.8%) but lower rate of cardiomyopathy (30.3%) than males in this cohort. Based on multiple COX stepwise regression and ROC curve analysis, diastolic blood pressure (DBP), serum sodium, serum creatinine, and pulmonary artery systolic pressure (PASP) were identified as independent predictors of all-cause death in male AHF patients, while systolic blood pressure (SBP), serum aspartate transaminase (AST), serum creatinine, and serum D-dimer as independent predictors in females. Kaplan-Meier analysis showed a higher probability of all-cause death over time in male AHF patients with DBP ≤ 77 mmHg, serum sodium ≤ 138.5 mM, serum creatinine ≥ 126.2 μM, or PASP ≥ 52 mmHg, and in female AHF patients with SBP ≤ 129 mmHg, serum AST > 29.3 U/L, serum creatinine ≥ 102.7 μM, or serum D-dimer ≥ 1.76 mg/L. In conclusion, these data provide novel insights into gender differences in prognostic markers of outcomes of AHF patients.

Gender Differences in Atrial Fibrillation: A Review of Epidemiology, Management, and Outcomes

Atrial fibrillation is the most common sustained cardiac arrhythmia. The scope and impact of atrial fibrillation are wide; it can affect cardiac function, functional status, and quality of life, and it confers a stroke risk. There are sex differences in atrial fibrillation across the scope of the disease process, from epidemiology and causative mechanisms to management and outcomes. The approach to management of atrial fibrillation differs between women and men, and there are sex differences in response to medical therapy and catheter ablation. There are many gaps in our knowledge of the gender differences in atrial fibrillation, and many opportunities for future research.

Female gender and mortality risk in decompensated heart failure

BACKGROUND

Still there is conflicting evidence about gender-related differences in prognosis among patients with heart failure. This prognostic uncertainty may have implications for risk stratification and planning management strategy. The aim of the present study was to explore the association between gender and one-year mortality in patients admitted with acute decompensated heart failure (ADHF).

METHODS

We studied 1513 patients. The Cumulative Incidence Function (CIF) method was used to estimate the absolute rate of mortality, heart transplantation (HT)/ventricular assist device (VAD) implantation, and survival free of HT/VAD implantation at 1year. An interaction analysis was performed to assess the association between covariates, gender, and mortality risk. Propensity score matching and Cox regression were used to compare mortality rates in the gender subgroups.

RESULTS

The CIF estimates of 1-year mortality, HT/VAD implantation, and survival free of HT/VAD implantation at 1year were 33.1%, 7.0%, and 59.9% for women and 30.2%, 10.2%, and 59.6% for men, respectively. Except for diabetes, there was no significant interaction between gender, covariates, and mortality risk. In the matched cohort, the hazard ratio of death for women was 1.19 (95% confidence intervals [CIs]: 0.90-1.59; p=.202). After adjusting for age and baseline risk, the hazard ratio of death for women was 1.18 (95% CIs: 0.95-1.43; p=.127). The use of gender-specific predictive models did not allow improving the accuracy of risk prediction.

CONCLUSIONS

Our data strongly suggest that women and men have comparable outcome in the year following a hospitalization for ADHF.

Sex Differences in Heart Failure

Heart failure (HF) represents a global pandemic health problem with a high impact on health-care costs, affecting about 26 million adults worldwide. The overall HF prevalence and incidence are ~2% and ~0.2% per year, respectively, in Western countries, with half of the HF population with reduced ejection fraction (HFpEF) and half with preserved (HFpEF) or mid-range ejection fraction (HFmrEF). Sex differences may exist in HF. More males have HFrEF or HFmrEF and an ischemic etiology, whereas more females have HFpEF and hypertension, diastolic dysfunction, and valvular pathologies as HF etiologies. Females are generally older, have a higher EF, higher frequency of HF-related symptoms, and lower NYHA functional status. Generally, it is observed that female HF patients tend to have more comorbidities such as atrial fibrillation, diabetes, hypertension, anemia, iron deficiency, renal disease, arthritis, frailty, depression, and thyroid abnormalities. However, overall, females have better prognosis in terms of mortality and hospitalization risk compared with men, regardless of EF. Potential sex differences in HF characteristics may be underestimated because of the underrepresentation of females in cardiovascular research and, in particular, the sex imbalance in clinical trial enrollment may avoid to identify sex-specific differences in treatments' benefit.

Differences of psychological features in patients with heart failure with regard to gender and aetiology - Results of a CAPS-LOCK-HF (Complex Assessment of Psychological Status Located in Heart Failure) study

OBJECTIVE

Objective of the study was to assess the psychological state of HF patients with reduced ejection fraction (HFrEF) with regard to gender and aetiology.

METHODS

758 patients with HFrEF (mean age - 64±11years, men - 79%, NYHA class III-IV - 40%, ischemic aetiology - 61%) in a prospective Polish multicenter Caps-Lock-HF study. Scores on five different self-report inventories: CISS, MHLC, GSES, BDI and modified Mini-MAC were compared between the sexes taking into account the aetiology of HFrEF.

RESULTS

There were differences in the CISS and BDI score between the genders - women had higher CISS (emotion- and avoidance-oriented) and BDI (general score - 14.2±8.7 vs 12.3±8.6, P<0.05; subscale - somatic score - 7.3±3.7 vs 6.1±3.7, P<0.05). In the ischemic subpopulation, women had higher BDI (general and subscales) than men. In the non-ischemic subpopulation the differences between genders were limited to CISS scale. In a multivariable analysis with demographic and clinical data female sex, NYHA class, atrial fibrillation and diabetes mellitus determined BDI score. Similarly, in the ischemic subpopulation, the female sex, NYHA class and atrial fibrillation determined the BDI, while in the non-ischemic population NYHA class was the only factor that influenced the BDI score. Adding the psychological data made a significant additional contribution to the prediction of depression status.

CONCLUSIONS

There are distinct differences in psychological features with regard to gender in patients with HFrEF. Women demonstrate less favourable psychological characteristics. Gender-related differences in BDI score are especially explicit in patients with ischemic aetiology of HF. The BDI score is related to psychological predisposition.

Sex differences in predictors of ischemic stroke: current perspectives

Globally, stroke is a significant public health concern affecting more than 33 million individuals. Of growing importance are the differences between males and females in the predictors and overall risk of stroke. Given that women have a higher lifetime risk for stoke and account for more than half of all stroke deaths, sex-specific stroke risk factors merit investigation and may help target public health interventions. This review aims to discuss the current body of knowledge regarding sex-specific predictors of ischemic stroke including both modifiable and non-modifiable risk factors, as well as specific pathologies known to increase stroke risk.
