Patient reported outcome in HFpEF: Sex-specific differences in quality of life and association with outcome

Sex differences in the diagnostic algorithm of screening for heart failure by symptoms and NT-proBNP in patients with type 2 diabetes

OBJECTIVES

This study aimed to assess the guideline recommended diagnostic tools NT-proBNP and NYHA classification, with a focus on sex-specific differences.

BACKGROUND

Patients with Type 2 Diabetes (T2D) face a heart failure (HF) risk up to four times higher than those without T2D, particularly affecting women more than twice as much as men. Despite distinct pathophysiological differences between men and women, there are currently no sex-specific recommendations for the diagnostic algorithm of HF in diabetic patients.

METHODS

A total of 2083 patients with T2D were enrolled, and the primary endpoint was heart failure during hospitalization within a 5-year timeframe. The secondary endpoint was all-cause death.

RESULTS

In female patients, frequency of HF diagnosis prior to or during hospitalization and mortality did not differ significantly between NYHA II and III, in contrast to male patients. Additionally, there was no notable difference in mean NT-proBNP levels between NYHA stage II and III only in female patients. The multivariable regression analysis highlighted NYHA classification not to be a predictor of NT-proBNP levels in female but solely in male patients. On multivariable Cox regression NYHA score was also no significant risk factor for occurence of HF in female patients. Furthermore, there was no significant disparity in mortality between men with NT-proBNP levels between 125 and 400 pg/ml and those below 125 pg/ml, whereas in women mortality was significantly higher in the group with NT-proBNP levels between 125 and 400 pg/ml than below 125 pg/ml.

CONCLUSION

These findings suggest that NYHA classification may not be the most suitable tool for assessing the diagnosis of HF in female patients with T2D. Moreover, the need for consideration of a more symptom-independent screening for HF in female patients with T2D and re-evaluation of current guidelines especially regarding sex-specific aspects is highlighted.

HFpEF and sex: understanding the role of sex differences

Heart failure is a complex clinical syndrome with many etiological factors and complex pathophysiology affecting millions worldwide. Males and females can have distinct clinical presentation and prognosis, and there is an emerging understanding of the factors that highlight the similarities and differences to synthesize and present available data for sex-specific differences in heart failure with preserved ejection fraction (HFpEF). While the majority of data demonstrate more similarities than differences between females and males in terms of heart failure, there are key differences. Data showed that females have a higher risk of developing HFpEF, but a lower risk of mortality and hospitalization. This can be conditioned by different profiles of comorbidities, postmenopausal changes in sex hormone levels, higher levels of inflammation and chronic microvascular dysfunction in females. These factors, combined with different left ventricular dimensions and function, which are more pronounced with age, lead to a higher prevalence of LV diastolic dysfunction at rest and exercise. As a result, females have lower exercise capacity and quality of life when compared to males. Females also have different activities of systems responsible for drug transformation, leading to different efficacy of drugs as well as higher risk of adverse drug reactions. These data prove the necessity for creating sex-specific risk stratification scales and treatment plans.

The Oxygen Cascade According to HFpEF Likelihood: A Focus on Sex Differences

Background

Women are at greater risk for heart failure with preserved ejection fraction (HFpEF).

Objectives

The aim of the study was to compare sex differences in the pathophysiology of exertional breathlessness in patients with high vs low HFpEF likelihood.

Methods

This cohort study evaluated consecutive patients (n = 1,936) with unexplained dyspnea using cardiopulmonary exercise testing and simultaneous echocardiography and quantified peak oxygen uptake (peak VO2) and its determinants. HFpEF was considered likely when the H2FPEF or HFA-PEFF score was ≥6 or ≥5, respectively. Sex differences were evaluated with the Student's t-test or Mann-Whitney U test and determinants of exercise capacity with a multivariable linear regression.

Results

The cohort included 1,963 patients (49% women and 28% [n = 555] with a high HFpEF likelihood). HFpEF likelihood did not impact the magnitude of sex differences in peak VO2 and its determinants. Overall, women had lower peak VO2 (mean difference -4.4 mL/kg/min [95% CI: -3.7 to -5.1 mL/kg/min]) secondary to a reduced O2 delivery (-0.5 L/min [95% CI: -0.4 to -0.6 L/min]) and less oxygen extraction (-2.9 mL/dL [95% CI: -2.5 to -3.2 mL/dL]). Reduced O2 delivery was due to lower hemoglobin (-1.2 g/dL [95% CI: -0.9 to -1.5 g/dL]) and smaller stroke volume (-15 mL [95% CI: -14 to -17 mL]). Women demonstrated increased mean pulmonary artery pressure/cardiac output slope (+0.5 mm Hg/L/min [95% CI: 0.3-0.7 mm Hg/L/min]) and left ventricular ejection fraction (+1% [95% CI: 1%-2%]), while they had smaller left ventricular end-diastolic volumes (-9 mL/m2 [95% CI: -8 to -11 mL/m2]) and mass (-12 g/m2 [95% CI: -9 to -14 g/m2]) and more often iron deficiency (55% vs 33%; P < 0.001).

Conclusions

Women with unexplained dyspnea had significantly lower peak VO2, regardless of HFpEF likelihood, attributed to both lower peak exercise O2 delivery and extraction. This suggests that physiologic sex differences, and not HFpEF likelihood, are an important factor contributing to functional limitations in females with exertional breathlessness.

Differences in Health-Related Quality of Life among Patients with Heart Failure

Heart failure (HF) is characterized by a progressive clinical course marked by frequent exacerbations and repeated hospitalizations, leading to considerably high morbidity and mortality rates. Patients with HF present with a constellation of bothersome symptoms, which range from physical to psychological and mental manifestations. With the transition to more advanced HF stages, symptoms become increasingly more debilitating, interfere with activities of daily living and disrupt multiple domains of life, including physical functioning, psychological status, emotional state, cognitive function, intimate relationships, lifestyle status, usual role activities, social contact and support. By inflicting profuse limitations in numerous aspects of life, HF exerts a profoundly negative impact on health-related quality of life (HRQOL). It is therefore not surprising that patients with HF display lower levels of HRQOL compared not only to the general healthy population but also to patients suffering from other chronic diseases. On top of this, poor HRQOL in patients with HF becomes an even greater concern considering that it has been associated with unfavorable long-term outcomes and poor prognosis. Nevertheless, HRQOL may differ significantly among patients with HF. Indeed, it has consistently been reported that women with HF display poorer HRQOL compared to men, while younger patients with HF tend to exhibit lower levels of HRQOL than their older counterparts. Moreover, patients presenting with higher New York Heart Association (NYHA) functional class (III-IV) have significantly more impaired HRQOL than those in a better NYHA class (I-II). Furthermore, most studies report worse levels of HRQOL in patients suffering from HF with preserved ejection fraction (HFpEF) compared to patients with HF with reduced ejection fraction (HFrEF) or HF with mildly reduced ejection fraction (HFmrEF). Last, but not least, differences in HRQOL have been noted depending on geographic location, with lower HRQOL levels having been recorded in Africa and Eastern Europe and higher in Western Europe in a recent large global study. Based on the observed disparities that have been invariably reported in the literature, this review article aims to provide insight into the underlying differences in HRQOL among patients with HF. Through an overview of currently existing evidence, fundamental differences in HRQOL among patients with HF are analyzed based on sex, age, NYHA functional class, ejection fraction and geographic location or ethnicity.

Lagging behind the Western countries: the knowledge gaps of gender differences in heart failure in Asia

Gender differences in heart failure (HF), ranging from epidemiological and pathophysiological factors to therapeutic response and prognosis, have been well documented in Western countries, especially in Europe and North America. The above gender differences in HF found in Westerners are rarely investigated in Asians. In this review, we explore the worrying knowledge gap on the gender differences in HF that existed in Asia in contrast with Western populations based on the following four aspects: epidemiology, risk factors, therapy, and prognosis. Finally, we conclude that investigations of gender differences in HF in Asia lag behind those in Europe and North America. Future work is required to establish and better use the high-level, population-based cohorts and develop our own high-quality, convincing clinical trials to deliver robust gender-specific conclusions in Asia.

Gender Differences in Anxiety, Depression, Insomnia, and Quality of Life in Heart Failure With Preserved Ejection Fraction: A Multicenter, Cross-sectional Study

BACKGROUND

Patients with heart failure with preserved ejection fraction (HFpEF) are more often female, but gender differences in psychological distress in patients with HFpEF have not been determined.

OBJECTIVE

We aimed to compare anxiety, depression, insomnia, and quality of life (QoL) between women and men with HFpEF.

METHODS

A total of 263 consecutive hospitalized patients with HFpEF were enrolled in a multicenter study. Demographic and clinical characteristics were recorded. Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale (HADS), insomnia was assessed by the Insomnia Severity Index and Pittsburgh Sleep Quality Index, and QoL was assessed by the Kansas City Cardiomyopathy Questionnaire.

RESULTS

Women accounted for 59% and men accounted for 41% of the patients with HFpEF. Women and men had similar New York Heart Association functional class and N-terminal pro-brain natriuretic peptide levels. Between women and men with HFpEF, similar depression prevalence (HADS-D: 4.9 ± 3.7 vs 4.1 ± 3.6, P = .222), insomnia severity (Insomnia Severity Index: 9.3 ± 6.4 vs 8.0 ± 6.5, P = .120), and QoL (Kansas City Cardiomyopathy Questionnaire: 46.6 ± 12.6 vs 47.6 ± 12.7, P = .738) were found when adjusting for potential confounders. Women had more severe anxiety (HADS-Anxiety: 2.4 ± 2.9 vs 1.6 ± 2.3, P = .025) and worse sleep quality (Pittsburgh Sleep Quality Index: 9.9 ± 4.6 vs 8.7 ± 4.5, P = .046) compared with men after adjustment.

CONCLUSIONS

There were no gender differences in depression, insomnia, and QoL in patients with HFpEF when adjusting for confounders. Women with HFpEF suffered more severe anxiety and sleep quality than men after adjustment. Thus, it is recommended that psychological distress in patients with HFpEF be assessed in clinical practice, and gender differences taken into consideration.

Use of patient-reported outcomes in heart failure: from clinical trials to routine practice

Heart failure (HF) is a complex syndrome that affects mortality/morbidity and acts at different levels in the patient's life, resulting in a drastic impairment in multiple aspects of daily activities (e.g. physical, mental/emotional, and social) and leading to a reduction in quality of life. The definition of disease status and symptom severity has been traditionally based on the physician assessment, while the patient's experience of disease has been long overlooked. The active participation of patients in their own care is necessary to better understand the perception of disease and the multiple aspects of life affected, and to improve adherence to treatments. Patient-reported outcomes (PROs) aim to switch traditional care to a more patient-centred approach. Although PROs demonstrated precision in the evaluation of disease status and have a good association with prognosis in several randomized controlled trials, their implementation into clinical practice is limited. This review discusses the modalities of use of PROs in HF, summarizes the most largely adopted PROs in HF care, and provides an overview on the application of PROs in trials and the potential for their transition to clinical practice. By discussing the advantages and the disadvantages of their use, the reasons limiting their application in daily clinical routine, and the strategies that may promote their implementation, this review aims to foster the systematic integration of the patient's standpoint in HF care.

The clinical relevance of quality of life in heart failure patients with preserved ejection fraction

AIMS

Patient reported outcomes (PROs) are gradually being incorporated into daily practice to assess individual health-related quality of life (QOL). However, despite accumulating evidence of the prognostic utility of heart failure (HF)-specific QOL indices, evidence on the generic QOL score is scarce, especially in patients with HF with preserved ejection fraction (HFpEF).

METHODS AND RESULTS

Patient data were extracted from the Prospective mUlticenteR obServational stUdy of patIenTs with Heart Failure with Preserved Ejection Fraction (PURSUIT HFpEF) study. EuroQol 5 dimensions 5-level (EQ-5D-5L) data were obtained at discharge to evaluate patients' health-related QOL. The study population (n = 864) was divided into tertiles based on their EQ-5D-5L index as follows: low EQ-5D-5L 0.038-0.664 (n = 287), middle EQ-5D-5L 0.665-0.867 (n = 293), and high EQ-5D-5L 0.871-1.000 (n = 284). A total of 206 patients died over a mean follow-up period of 2.0 ± 1.2 years. Kaplan-Meier analysis revealed that the risk of mortality increased with the tertile of the EQ-5D-5L index (34% vs. 23% vs. 14%, P < 0.001). Cox multivariable analysis revealed that patients with EQ-5D-5L index in the low and middle tertiles had a significantly greater risk of mortality than those with EQ-5D-5L index in the high tertile [low EQ-5D-5L: adjusted hazard ratio (HR): 1.81 (1.12-2.92), P = 0.002, middle EQ-5D-5L: adjusted HR 1.91 (1.21-3.03), P = 0.006]. Among the dimensions of EQ-5D-5L, mobility (P = 0.014), self-care (P = 0.023) and usual activities (P = 0.008) were significant factors associated with all-cause mortality after multivariable adjustment.

CONCLUSIONS

EQ-5D-5L is useful tool for risk stratification in patients with HFpEF.

Sex differences in heart failure with preserved ejection fraction: From traditional risk factors to sex-specific risk factors

Heart failure with preserved ejection fraction has a higher prevalence in women versus men. There are several proposed mechanisms to explain this sex discrepancy including differences in cardiovascular adaptation to comorbidities and potential underlying etiologic mechanisms. In this review, we summarize sex differences in traditional risk factors, such as obesity, diabetes, hypertension, and coronary artery disease, which contribute to the development of heart failure with preserved ejection fraction in women. Furthermore, we explore female-specific risk factors, such as sex hormones, adverse pregnancy outcomes, and other reproductive factors, which may explain the predominance of heart failure with preserved ejection fraction in women. Beyond sex differences in risk factors, there are also significant sex differences in outcomes with women reporting lower quality of life but overall better survival versus men. Finally, while treatment options for patients with heart failure with preserved ejection fraction are still limited, sex differences have also been reported for the available therapies, with suggestion of preferential benefit of specific heart failure with preserved ejection fraction therapies in women. Further work is required to better understand sex differences in heart failure with preserved ejection fraction, including deeper understanding of pathophysiological mechanisms, derivation of more accurate risk stratification models, and increased representation of women in clinical trials.

Baseline characteristics of 547 new onset heart failure patients in the PREFERS heart failure study

Aim

Methods and results

Conclusions

Longitudinal study of patients' health-related quality of life using EQ-5D-3L in 11 Swedish National Quality Registers

OBJECTIVE

To compare problems reported in the five EQ-5D-3L dimensions and EQ VAS scores at baseline and at 1-year follow-up among different patient groups and specific diagnoses in 11 National Quality Registers (NQRs) and to compare these with the general population.

DESIGN

Longitudinal, descriptive study.

PARTICIPANTS

2 66 241 patients from 11 NQRs and 49 169 participants from the general population were included in the study.

PRIMARY AND SECONDARY OUTCOME MEASURES

Proportions of problems reported in the five EQ-5D-3L dimensions, EQ VAS scores of participants' own health and proportions of participants and mean/median EQ VAS score in the Paretian Classification of Health Change (PCHC) categories.

RESULTS

In most of the included registers, and the general population, problems with pain/discomfort were the most frequently reported at baseline and at 1-year follow-up. Mean EQ VAS score (SD) ranged from 45.2 (22.4) among disc hernia patients to 88.1 (15.3) in wrist and hand fracture patients at baseline. They ranged from 48.9 (20.9) in pulmonary fibrosis patients to 83.3 (17.4) in wrist and hand fracture patients at follow-up. The improved category of PCHC, improvement in at least one dimension without deterioration in any other, accounted for the highest proportion in several diagnoses, corresponding with highest improvement in mean EQ VAS score.

CONCLUSIONS

The study documented self-reported health of several different patient groups using the EQ-5D-3L in comparing with the general population. This demonstrated the important role of patient-reported outcomes in routine clinical care, to assess and follow-up health status and progress within different groups of patients. The EQ-5D-3L descriptive system and EQ VAS have an important role in providing a 'common denominator', allowing comparisons across NQRs and specific diagnoses.

The Impact of Clinical, Biochemical, and Echocardiographic Parameters on the Quality of Life in Patients with Heart Failure with Reduced Ejection Fraction

Despite significant advances in HF diagnosis and treatment over the recent decades, patients still characterize poor long-term prognosis with many recurrent hospitalizations and reduced health-related quality of life (HRQoL). We aimed to check the potential relationship between clinical, biochemical, or echocardiographic parameters and HRQoL in patients with HF with reduced ejection fraction (HFrEF). We included 152 adult patients hospitalized due to chronic HFrEF. We used the WHOQoL-BREF questionnaire to assess HRQoL and GNRI to evaluate nutritional status. We also analyzed several biochemical parameters and left ventricle ejection fraction. Forty (26.3%) patients were hospitalized due to HF exacerbation and 112 (73.7%) due to planned HF evaluation. The median age was 57 (48–62) years. Patients with low somatic HRQoL score had lower transferrin saturation (23.7 ± 11.1 vs. 29.7 ± 12.5%; p = 0.01), LDL (2.40 (1.80–2.92) vs. 2.99 (2.38–3.60) mmol/L; p = 0.001), triglycerides (1.18 (0.91–1.57) vs. 1.48 (1.27–2.13) mmol/L; p = 0.006) and LVEF (20 (15–25) vs. 25 (20–30)%; p = 0.003). TIBC (64.9 (58.5–68.2) vs. 57.7 (52.7–68.6); p = 0.02) was significantly higher in this group. We observed no associations between HRQoL and age or gender. The somatic domain of WHOQoL-BREF in patients with HFrEF correlated with the clinical status as well as biochemical and echocardiographic parameters. Assessment of HRQoL in HFrEF seems important in everyday practice and can identify patients requiring a special intervention

Sex Differences in Characteristics and Outcomes in Elderly Heart Failure Patients With Preserved Ejection Fraction: A Post-hoc Analysis From TOPCAT

Introduction: Although the impact of sex on patient outcomes for heart failure (HF) with preserved ejection fraction (HFpEF) has been reported, it is still unclear whether this impact is applicable for elderly patients with HFpEF. This study was conducted as a secondary analysis from a large randomized controlled trial-The Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist Trial (TOPCAT)-to evaluate the impact of sex differences on the baseline characteristics and outcomes of HFpEF patients who were older than 70 years. Methods: Baseline characteristic of elderly patients were compared between men and women. Primary outcomes were cardiovascular (CV) mortality and HF-related hospitalization, whereas secondary outcomes were all-cause mortality and all-cause hospitalization. Cox regression models were used to determine the effect of sex differences on patient outcomes. Results: A total of 1,619 patients were included in the study: 898 (55.5%) women and 721 (44.5%) men. Age was similar between women and men. Women had fewer comorbidities but worse cardiac function than men. The rate of primary outcomes was lower in women than in men (18.4 vs. 27.5%; p < 0.001), including rate of CV mortality (8.9 vs. 14.8%; p < 0.001) and HF-related hospitalization (13.4 vs. 18.2%; p = 0.008). All-cause mortality was also lower in women than in men (15.6 vs. 25.4%; p < 0.001). After adjustment for baseline characteristics, Cox regression analysis showed that female sex was a protective factor for CV mortality [hazard ratio (HR): 0.53; 95% confidence interval (CI): 0.40-0.73], HF-related hospitalization (HR: 0.71; 95% CI: 0.55-0.93), and all-cause mortality (HR: 0.59; 95% CI: 0.47-0.75). Although spironolactone significantly reduced the rate of all-cause mortality in women even after adjusting for baseline characteristics (HR: 0.68; 95% CI: 0.48-0.96; p = 0.028), no significant multivariate association was noted between sex and treatment effects (p = 0.190). Conclusion: Among elderly patients with HFpEF, women had worse cardiac function but better survival and lower HF-related hospitalization rate than men.

Psychometric Evaluation of the Kansas City Cardiomyopathy Questionnaire in Men and Women With Heart Failure

BACKGROUND

The Kansas City Cardiomyopathy Questionnaire (KCCQ) has been psychometrically evaluated in multiple heart failure (HF) populations, but the comparability of its psychometric properties between men and women is unknown.

METHODS

Data from 3 clinical trials (1 in stable HF with preserved ejection fraction, 1 each in stable and acute HF with reduced ejection fraction) and 1 prospective cohort study (stable HF with reduced ejection fraction), incorporating 6773 men and 3612 women with HF, were used to compare the construct validity, internal and test-retest reliability, ability to detect change, predict mortality and hospitalizations and minimally important differences between the 2 sexes. Interactions of the KCCQ overall summary and subdomain scores by sex were independently examined.

RESULTS

The KCCQ-Overall Summary score correlated well with New York Heart Association functional class in both sexes across patients with stable (correlation coefficient: -0.40 in men versus -0.49 in women) and acute (-0.37 in men versus -0.34 in women) HF. All KCCQ subdomains demonstrated concordant relationships with relevant comparison standards with no significant interactions by sex in 19 of 21 of these construct validity analyses. All KCCQ scores were equally predictive and other psychometric evaluations showed similar results by sex: test-retest reliability (intraclass correlation coefficient 0.94 in men versus 0.92 in women), responsive to change (standardized response mean 1.01 in both sexes), as were the minimally important differences and internal reliability.

CONCLUSIONS

The psychometric properties of the KCCQ, in terms of validity, prognosis, reliability, and sensitivity to change, are comparable in men and women with HF with preserved ejection fraction and HF with reduced ejection fraction.

Variations in Patients' Overall Assessment of Their Health Across and Within Disease Groups Using the EQ-5D Questionnaire: Protocol for a Longitudinal Study in the Swedish National Quality Registers

BACKGROUND

EQ-5D is one of the most commonly used questionnaires to measure health-related quality of life. It is included in many of the Swedish National Quality Registers (NQRs). EQ-5D health states are usually summarized using "values" obtained from members of the general public, a majority of whom are healthy. However, an alternative, which remains to be studied in detail, is the potential to use patients' self-reported overall health on the visual analog scale (VAS) as a means of capturing experience-based perspective.

OBJECTIVE

The aim of this study is to assess EQ VAS as a valuation method with an experience-based perspective through comparison of its performance across and within patient groups, and with that of the general population in Sweden.

METHODS

Data on nearly 700,000 patients from 12 NQRs covering a variety of diseases/conditions and nearly 50,000 individuals from the general population will be analyzed. The EQ-5D-3L data from the 12 registers and EQ-5D-5L data from 2 registers will be used in the analyses. Longitudinal studies of patient-reported outcomes among different patient groups will be conducted in the period from baseline to 1-year follow-up. Descriptive statistics and analyses comparing EQ-5D dimensions and observed self-assessed EQ VAS values across and within patient groups will be performed. Comparisons of the change in health state and observed EQ VAS values at 1-year follow-up will also be undertaken. Regression models will be used to assess whether EQ-5D dimensions predict observed EQ VAS values to investigate patient value sets in each patient group. These will be compared across the patient groups and with the existing Swedish experience-based VAS and time trade-off value sets obtained from the general population.

RESULTS

Data retrieval started in May 2019 and data of patients in the 12 NQRs and from the survey conducted among the general population have been retrieved. Data analysis is ongoing on the retrieved data.

CONCLUSIONS

This research project will provide information on the differences across and within patient groups in terms of self-reported health status through EQ VAS and comparison with the general population. The findings of the study will contribute to the literature by exploring the potential of self-assessed EQ VAS values to develop value sets using an experience-based perspective.

Association between early intensive care or coronary care unit admission and post-discharge performance of activities of daily living in patients with acute decompensated heart failure

The management of acute decompensated heart failure often requires intensive care. However, the effects of early intensive care unit/coronary care unit admission on activities of daily living (ADL) in acute decompensated heart failure patients have not been precisely evaluated. Thus, we retrospectively assessed the association between early intensive care unit admission and post-discharge ADL performance in these patients. Acute decompensated heart failure patients (New York Heart Association I–III) admitted on emergency between April 1, 2014, and December 31, 2018, were selected from the Diagnosis Procedure Combination database and divided into intensive care unit/coronary care unit (ICU) and general ward (GW) groups according to the hospitalization type on admission day 1. The propensity score was calculated to create matched cohorts where admission style (intensive care unit/coronary care unit admission) was independent of measured baseline confounding factors, including ADL at admission. The primary outcome was ADL performance level at discharge (post-ADL) defined according to the Barthel index. Secondary outcomes included length of stay and total hospitalization cost (expense). Overall, 12231 patients were eligible, and propensity score matching created 2985 pairs. After matching, post-ADL was significantly higher in the ICU group than in the GW group [mean (standard deviation), GW vs. ICU: 71.5 (35.3) vs. 78.2 (31.2) points, P<0.001; mean difference: 6.7 (95% confidence interval, 5.1–8.4) points]. After matching, length of stay was significantly shorter and expenses were significantly higher in the ICU group than in the GW group. Stratified analysis showed that the patients with low ADL at admission (Barthel index score <60) were the most benefited from early intensive care unit/coronary care unit admission. Thus, early intensive care unit/coronary care unit admission was associated with improved post-ADL in patients with emergency acute decompensated heart failure admission.

Esto exige un mayor desarrollo investigativo que permita conocer este fenómeno en el contexto colombiano y latinoamericano.

Burden and Quality of Life Among Female and Male Patients with Heart Failure in Europe: A Real-World Cross-Sectional Study

PURPOSE

To characterize symptoms, clinical burden, and health-related quality of life (HRQoL) among women and men with heart failure (HF) with a left ventricular ejection fraction (LVEF) of ≤60% in Europe.

PATIENTS AND METHODS

A real-world cross-sectional study was conducted in France, Germany, Italy, Spain, and United Kingdom from June to November 2019. Patient record forms were completed by 257 cardiologists and 158 general practitioners for consecutive patients with HF. The same patients were invited to complete a questionnaire comprising patient-reported outcomes: the Minnesota Living with Heart Failure Questionnaire (MLHFQ), five-level five-dimension EuroQol questionnaire (EQ-5D-5L), Visual Analogue Scale (VAS), and Work Productivity and Activity Impairment questionnaire.

RESULTS

The mean age of 804 patients (men, n=517; women, n=287) was 68.6 years (men, 67.8 years; women, 70.2 years; p=0.0022). The mean LVEF was 44.7% (men, 43.6%; women, 46.8%; p<0.0001). Patients reported dyspnoea when active (overall, 55.7%; men, 56.0%; women, 55.3%), fatigue/weakness/faintness (34.5%; men, 32.9%; women, 37.2%), and oedema (20.3%; men, 18.7%; women, 23.1%) as the most troublesome HF symptoms. Overall, 54.1% of patients reported low mood/depression (men, 50.8%; women, 60.1%). The overall MLHFQ mean score was higher (ie, poorer HRQoL) among women vs men (37.9 vs 34.6; p=0.0481). MLHFQ was consistently higher (ie, poorer HRQoL) for women vs men across the physical (18.6 vs 16.6; p=0.0041) and emotional (9.4 vs 7.9; p=0.0021) scoring domains. Mean EQ-5D utility (0.69 vs 0.75; p=0.0046) and VAS scores (55.4 vs 61.3; p<0.0001) were lower among women compared with men. Overall, 23.4% of patients were hospitalized owing to HF in the previous year (men, 22.7%; women, 24.6%). Patients reported 43.2% activity impairment due to HF (men, 41.6%; women, 46.4%; p=0.01).

CONCLUSION

HF causes a substantial burden on patients, with a greater burden among women vs men. This gender-related difference is consistent with other HF studies, warranting further research to understand the underlying reasons.

Characterization of the inflammatory-metabolic phenotype of heart failure with a preserved ejection fraction: a hypothesis to explain influence of sex on the evolution and potential treatment of the disease

Accumulating evidence points to the existence of an inflammatory-metabolic phenotype of heart failure with a preserved ejection fraction (HFpEF), which is characterized by biomarkers of inflammation, an expanded epicardial adipose tissue mass, microvascular endothelial dysfunction, normal-to-mildly increased left ventricular volumes and systolic blood pressures, and possibly, altered activity of adipocyte-associated inflammatory mediators. A broad range of adipogenic metabolic and systemic inflammatory disorders - e.g. obesity, diabetes and metabolic syndrome as well as rheumatoid arthritis and psoriasis - can cause this phenotype, independent of the presence of large vessel coronary artery disease. Interestingly, when compared with men, women are both at greater risk of and may suffer greater cardiac consequences from these systemic inflammatory and metabolic disorders. Women show disproportionate increases in left ventricular filling pressures following increases in central blood volume and have greater arterial stiffness than men. Additionally, they are particularly predisposed to epicardial and intramyocardial fat expansion and imbalances in adipocyte-associated proinflammatory mediators. The hormonal interrelationships seen in inflammatory-metabolic phenotype may explain why mineralocorticoid receptor antagonists and neprilysin inhibitors may be more effective in women than in men with HFpEF. Recognition of the inflammatory-metabolic phenotype may improve an understanding of the pathogenesis of HFpEF and enhance the ability to design clinical trials of interventions in this heterogeneous syndrome.

Gender Differences in Health-Related Quality of Life in Patients with Systolic Heart Failure: Results of the VIDA Multicenter Study

Previous studies have shown that heart failure is associated with worse health-related quality of life (HRQoL). The existence of differences according to gender remains controversial. We studied 1028 consecutive outpatients with heart failure and reduced ejection fraction (HFrEF) from a multicentre cross-sectional descriptive study across Spain that assessed HRQoL using two questionnaires (KCCQ, Kansas City Cardiomyopathy Questionnaire; and EQ-5D, EuroQoL 5 dimensions). The primary objective of the study was to describe differences in HRQoL between men and women in global scores and domains of health status of patients and explore gender differences and its interactions with heart failure related factors. In adjusted analysis women had lower scores in KCCQ overall summary scores when compared to men denoting worse HRQoL (54.7 ± 1.3 vs. 62.7 ± 0.8, p < 0.0001), and specifically got lower score in domains of symptom frequency, symptoms burden, physical limitation, quality of life and social limitation. No differences were found in domains of symptom stability and self-efficacy. Women also had lower scores on all items of EQ-5D (EQ-5D index 0.58 ± 0.01 vs. 0.67 ± 0.01, p < 0.0001). Finally, we analyzed interaction between gender and different clinical determinants regarding the presence of limitations in the 5Q-5D and overall summary score of KCCQ. Interestingly, there was no statistical significance for interaction for any variable. In conclusion, women with HFrEF have worse HRQoL compared to men. These differences do not appear to be mediated by clinical or biological factors classically associated with HRQoL nor with heart failure severity.

Adverse Drug Reactions to Guideline-Recommended Heart Failure Drugs in Women: A Systematic Review of the Literature

OBJECTIVES

This study sought to summarize all available evidence on sex differences in adverse drug reactions (ADRs) to heart failure (HF) medication.

BACKGROUND

Women are more likely to experience ADRs than men, and these reactions may negatively affect women's immediate and long-term health. HF in particular is associated with increased ADR risk because of the high number of comorbidities and older age. However, little is known about ADRs in women with HF who are treated with guideline-recommended drugs.

METHODS

A systematic search of PubMed and EMBASE was performed to collect all available information on ADRs to angiotensin-converting enzyme inhibitors, β-blockers, angiotensin II receptor blockers, mineralocorticoid receptor antagonists, ivabradine, and digoxin in both women and men with HF.

RESULTS

The search identified 155 eligible records, of which only 11 (7%) reported ADR data for women and men separately. Sex-stratified reporting of ADRs did not increase over the last decades. Six of the 11 studies did not report sex differences. Three studies reported a higher risk of angiotensin-converting enzyme inhibitor-related ADRs in women, 1 study showed higher digoxin-related mortality risk for women, and 1 study reported a higher risk of mineralocorticoid receptor antagonist-related ADRs in men. No sex differences in ADRs were reported for angiotensin II receptor blockers and β-blockers. Sex-stratified data were not available for ivabradine.

CONCLUSIONS

These results underline the scarcity of ADR data stratified by sex. The study investigators call for a change in standard scientific practice toward reporting of ADR data for women and men separately.

Coexisting Morbidities in Heart Failure: No Robust Interaction with the Left Ventricular Ejection Fraction

PURPOSE OF REVIEW

Heart failure (HF) patients often present with multiple coexisting morbidities. In this review, we contend that coexisting morbidities are highly prevalent and clinically important regardless of the left ventricular ejection fraction (LVEF).

RECENT FINDINGS

Multimorbidity is prevalent in the ambulatory subjects of the community and increases with age. Differences in the prevalence of coexisting morbidities between HF with preserved LVEF (> 50%), mid-range LVEF (40-50%), and reduced LVEF (< 40%) are either not demonstrable or whenever present are small and unrelated to morbidity and mortality. The constellation of coexisting morbidities together with the disease modifiers (age, sex, genes, other) defines the HF phenotype and outcome. There is no robust evidence supporting an interaction in HF patients between the prevalence and clinical significance of coexisting morbidities and the LVEF.

Sex Differences in Exercise Capacity and Quality of Life in Heart Failure With Preserved Ejection Fraction: A Secondary Analysis of the RELAX and NEAT-HFpEF Trials

BACKGROUND

Few studies have compared clinical characteristics, echocardiographic parameters, exercise capacity, and quality of life between women and men with heart failure with preserved ejection fraction (HFpEF).

METHODS AND RESULTS

Subjects in the NIH-sponsored RELAX (N = 216) and NEAT (N = 107) trials completed baseline echocardiography, the Minnesota Living with Heart Failure Questionnaire (MLHFQ), and 6-minute walk test (6MWT). In an exploratory analysis, multivariable linear regression models were used to associate clinical and imaging characteristics with baseline 6MWT distance and MLHFQ score in women and men. Our cohort included 158 (49%) men and 165 (51%) women. Men had higher prevalence of atrial arrhythmias, ischemic heart disease, diabetes, anemia, and left ventricular (LV) hypertrophy. 6MWT and MLHFQ score did not differ between sexes. In multivariable analysis, ischemic heart disease, diastolic dysfunction, and exercise capacity predicted MLHFQ score for men, whereas only age and body mass index predicted MLHFQ score for women.

CONCLUSIONS

Men with HFpEF had more comorbidities and LV hypertrophy than women with HFpEF. In men, quality of life was associated with diastolic dysfunction, ischemic heart disease, and exercise capacity. Further research is needed to identify determinants of quality of life in women with HFpEF.

The endothelial mineralocorticoid receptor: Contributions to sex differences in cardiovascular disease

Cardiovascular disease remains the leading cause of death for both men and women. The observation that premenopausal women are protected from cardiovascular disease relative to age-matched men, and that this protection is lost with menopause, has led to extensive study of the role of sex steroid hormones in the pathogenesis of cardiovascular disease. However, the molecular basis for sex differences in cardiovascular disease is still not fully understood, limiting the ability to tailor therapies to male and female patients. Therefore, there is a growing need to investigate molecular pathways outside of traditional sex hormone signaling to fully understand sex differences in cardiovascular disease. Emerging evidence points to the mineralocorticoid receptor (MR), a steroid hormone receptor activated by the adrenal hormone aldosterone, as one such mediator of cardiovascular disease risk, potentially serving as a sex-dependent link between cardiovascular risk factors and disease. Enhanced activation of the MR by aldosterone is associated with increased risk of cardiovascular disease. Emerging evidence implicates the MR specifically within the endothelial cells lining the blood vessels in mediating some of the sex differences observed in cardiovascular pathology. This review summarizes the available clinical and preclinical literature concerning the role of the MR in the pathophysiology of endothelial dysfunction, hypertension, atherosclerosis, and heart failure, with a special emphasis on sex differences in the role of endothelial-specific MR in these pathologies. The available data regarding the molecular mechanisms by which endothelial-specific MR may contribute to sex differences in cardiovascular disease is also summarized. A paradigm emerges from synthesis of the literature in which endothelial-specific MR regulates vascular function in a sex-dependent manner in response to cardiovascular risk factors to contribute to disease. Limitations in this field include the relative paucity of women in clinical trials and, until recently, the nearly exclusive use of male animals in preclinical investigations. Enhanced understanding of the sex-specific roles of endothelial MR could lead to novel mechanistic insights underlying sex differences in cardiovascular disease incidence and outcomes and could identify additional therapeutic targets to effectively treat cardiovascular disease in men and women.

Impact of diabetes and sex in heart failure with reduced ejection fraction patients from the ASIAN-HF registry

AIMS

To examine sex differences in clinical characteristics, echocardiographic features, quality of life and 1-year death or heart failure (HF) hospitalization outcomes in patients with/without diabetes mellitus (DM).

METHODS AND RESULTS

Utilizing the Asian Sudden Cardiac Death in HF (ASIAN-HF) registry, 5255 patients (mean age 59.6 ± 13.1, 78% men) with symptomatic HF with reduced ejection fraction (HFrEF) were stratified by DM status to address the research aims. Despite similar prevalence of DM between Asian men (43%) and women (42%), the odds of DM increased at lower body mass index in women vs. men (≥ 23 vs. ≥ 27.5 kg/m² , P_interaction  = 0.014). DM was more strongly related to chronic kidney disease in women vs. men [adjusted odds ratio (OR) 1.85, 95% confidence interval (CI) 1.33-2.57 vs. OR 1.32, 95% CI 1.11-1.56, P_interaction  = 0.009]. Sex also modified the relationship between DM and left ventricular geometry (P_interaction  = 0.003), whereby DM was associated with a more concentric left ventricular geometry in women than men. Women had lower quality of life than men (P < 0.001), in both DM and non-DM groups. DM was associated with worse composite outcomes at 1 year in women vs. men [hazard ratio (HR) 1.79, 95% CI 1.24-2.60 vs. HR 1.32, 95% CI 1.12-1.56; P_interaction  = 0.005).

CONCLUSIONS

Asian women with HFrEF were more likely to have DM despite a lean body mass index, a greater burden of chronic kidney disease and more concentric left ventricular geometry, compared to men. Furthermore, DM confers worse quality of life, irrespective of sex, and a greater risk of adverse outcomes in women than men. These data underscore the need for sex-specific approaches to diabetes in patients with HF.
