Ambulatory Advanced Heart Failure in Women: A Report From the REVIVAL Registry

Gender Differences Regarding Palliative Care Consultation Among Persons Hospitalized With Heart Failure

CONTEXT

Palliative care is increasingly recognized as an important aspect of heart failure (HF) management, but data on gender differences regarding palliative care needs are scarce.

OBJECTIVE

We retrospectively studied patients hospitalized with a primary diagnosis of HF who received an initial palliative care consultation in the Mount Sinai Health System to examine gender differences.

METHODS

From electronic health records, we extracted patient information, diagnostic codes, and the palliative care consult assessment which included the Karnofsky performance status (KPS) and the Edmonton symptom assessment scale (ESAS). The population was stratified according to self-identified gender. Unadjusted and adjusted generalized linear models were fitted to study the association of gender with KPS and ESAS scores.

RESULTS

Among 667 patients with HF who received a palliative care consultation, 327 (49.0%) were women. Women with HF were older than men and less likely to be married. As compared to men, women had worse functional status, were less likely to have capacity to designate a surrogate medical decision-maker, had a higher symptom burden and were more likely to experience severe symptoms at the time of initial palliative care consultation. Differences in functional status and symptom burden were particularly pronounced in young women and women identifying as Black or Hispanic. The association of gender with functional status and symptom burden remained statistically significant after adjusting for possible confounders.

CONCLUSION

As compared to men, women with HF were more severely impaired at the time of palliative care consult, and dedicated efforts to better address their needs are warranted.

Prognostic Value of Depressive Symptoms for Cardiovascular Events in Female Patients With Heart Failure With Reduced Ejection Fraction and Heart Failure With Preserved Ejection Fraction

BACKGROUND

Among those with heart failure (HF), women are more likely to develop depression than men. Few studies have focused on the outcomes of female patients with HF with depressive symptoms.

METHODS AND RESULTS

A total of 506 female patients with HF with preserved ejection fraction were included in this secondary analysis from the TOPCAT (Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist) cohort, and 439 female patients with HF with reduced ejection fraction were included from the HF-ACTION (Heart Failure: A Controlled Trial Investigating Outcomes of Exercise Training) cohort. Depressive symptoms were measured using the Patient Health Questionnaire-9 and Beck Depression Inventory-II. The depression class was categorized by severity, and the change in clinical depression class was defined as aggravated (1-grade increase) or improved (1-grade decrease). The prognostic value of depressive symptoms was determined by using multivariable Cox proportional hazards models. Female patients with improved depressive symptoms had worse depressive status at baseline and lower baseline Kansas City Cardiomyopathy Questionnaire scores. Depression class at the 12-month visit and depression class change were the dominant prognostic factors for cardiovascular death in female patients with HF with preserved ejection fraction (hazard ratio [HR], 1.43 [95% CI, 1.02-2.01], P=0.036; HR, 1.71 [95% CI, 1.14-2.55], P=0.009). Among the patients with HF with reduced ejection fraction, both the depression class at baseline and depression class change had significant prognostic effects on cardiovascular death (HR, 3.30 [95% CI, 1.70-6.39], P<0.001; HR, 2.21 [95% CI, 1.28-3.80], P=0.004). However, the prognostic value of depressive assessments for hospitalization in patients with HF is unclear.

CONCLUSIONS

In female patients with HF with reduced ejection fraction, the depression class at baseline was most strongly associated with cardiovascular death, whereas in female patients with HF with preserved ejection fraction, the change in depression class exhibited a more significant prognostic trend.

Sex-based differences in left ventricular assist device clinical outcomes

BACKGROUND

Heart failure (HF) continues to be a significant public health issue, posing a heightened risk of morbidity and mortality for both genders. Despite the widespread use of left ventricular assist device (LVAD), the influence of gender differences on clinical outcomes following implantation remains unclear.

OBJECTIVES

We investigated the impact of gender differences on readmission rates and other outcomes following LVAD implantation in patients admitted with advanced HF.

METHODS

We conducted a retrospective study of patients who underwent LVAD implantation for advanced HF between 2014 and 2020, using the Nationwide Readmissions Database. Our study cohort was divided into male and female patients. The primary outcome was 30-day readmission (30-dr), while secondary outcomes were inpatient mortality, length of stay (LOS), procedural complication rates, and periadmission rates. Multivariate linear, Cox, and logistic regression analyses were performed.

RESULTS

During the study period, 11,492 patients with advanced HF who had LVAD placement were identified. Of these, 22% (n = 2532) were females and 78% (n = 8960) were males. The mean age was 53.9 ± 10.8 years for females and 56.3 ± 10.5 years for males (adjusted Wald test, p < 0.01). Readmissions were higher in females (21% vs. 17%, p = 0.02) when compared to males. Cox regression analysis showed higher readmission events (hazard ratio: 1.24, 95% confidence interval: 1.01-1.52, p = 0.03) in females when compared to males. Inpatient mortality, LOS, and most procedural complication rates were not statistically significantly different between the two groups (p > 0.05, all).

CONCLUSION

Women experienced higher readmission rates and were more likely to be readmitted multiple times after LVAD implantation when compared to their male counterparts. However, there were no significant sex-based differences in inpatient mortality, LOS, and nearly all procedural complication rates. These findings suggest that female patients may require closer monitoring and targeted interventions to reduce readmission rates.

Addressing Barriers for Women with Advanced Heart Failure

PURPOSE OF REVIEW

Describe disparities in diagnosis and management between men and women with advanced heart failure (HF). Our goal is to identify barriers and suggest solutions.

RECENT FINDINGS

Women with advanced HF are less likely to undergo diagnostic testing and procedures (i.e., revascularization, implantable cardioverter defibrillators, cardiac resynchronization therapy, mechanical circulatory support, and orthotopic heart transplantation). Disparities related to gender create less favorable outcomes for women with advanced HF. The issues arise from access to care, paucity of knowledge, enrollment in clinical trials, and eligibility for advanced therapies. In this review, we propose a call to action to level the playing field in order to improve survival in women with advanced HF.

Special Considerations in the Care of Women With Advanced Heart Failure

Advanced heart failure (AHF) is associated with increased morbidity and mortality, and greater healthcare utilization. Recognition requires a thorough clinical assessment and appropriate risk stratification. There are persisting inequities in the allocation of AHF therapies. Women are less likely to be referred for evaluation of candidacy for heart transplantation or left ventricular assist device despite facing a higher risk of AHF-related mortality. Sex-specific risk factors influence progression to advanced disease and should be considered when evaluating women for advanced therapies. The purpose of this review is to discuss the role of sex hormones on the pathophysiology of AHF, describe the clinical presentation, diagnostic evaluation and definitive therapies of AHF in women with special attention to pregnancy, lactation, contraception and menopause. Future studies are needed to address areas of equipoise in the care of women with AHF.

Utilization of Standard Therapy and Adjunctive Isosorbide Dinitrate Pump with Clinical Outcomes in Acute Heart Failure Patients

BACKGROUND: Acute heart failure is a life-threatening medical condition. Thus, effective therapy is very important for this case. Utilization of standard therapy and adjunctive isosorbide dinitrate (ISDN) pump play an important role in reducing mortality, length of hospitalization, and national early warning score – NEWS 2. However, the research on the utilization of the ISDN pump as adjunctive therapy is still limited. AIM: This study aimed to analyze the association between utilization of standard therapy and adjunctive ISDN pump with clinical outcomes (mortality, length of hospitalization, and NEWS 2) in patients with acute heart failure. METHODS: This was a cohort retrospective observational study. The purposive sampling technique was utilized to select the acute heart failure patients in UNS Sukoharjo Hospital. All the data were obtained from medical records. Logistic regression was used to analyze the data. RESULTS: A total of 94 patients were included as the samples. There was a significant association between the utilization of standard therapy (OR=7.9; CI 95%= 3.1–20.4; p < 0.001) or ISDN pump (OR=0.3; CI 95%= 0.1–0.7; p < 0.001) with the length of hospitalization. However, there was no significant association between the utilization of standard therapy (OR=1.1; CI 95%= 0.2–6.6; p = 0.9) and ISDN pump (OR=0.2; CI 95%= 0.02–1.6; p = 0.1) with NEWS 2 on patients with acute heart failure. CONCLUSION: There was a significant association between the utilization of standard therapy and ISDN pump with the length of hospitalization.

The Canadian Women's Heart Health Alliance Atlas on the Epidemiology, Diagnosis, and Management of Cardiovascular Disease in Women - Chapter 5: Sex- and Gender-Unique Manifestations of Cardiovascular Disease

This Atlas chapter summarizes sex- and some gender-associated, and unique aspects and manifestations of cardiovascular disease (CVD) in women. CVD is the primary cause of premature death in women in Canada and numerous sex-specific differences related to symptoms and pathophysiology exist. A review of the literature was done to identify sex-specific differences in symptoms, pathophysiology, and unique manifestations of CVD in women. Although women with ischemic heart disease might present with chest pain, the description of symptoms, delay between symptom onset and seeking medical attention, and prodromal symptoms are often different in women, compared with men. Nonatherosclerotic causes of angina and myocardial infarction, such as spontaneous coronary artery dissection are predominantly identified in women. Obstructive and nonobstructive coronary artery disease, aortic aneurysmal disease, and peripheral artery disease have worse outcomes in women compared with men. Sex differences exist in valvular heart disease and cardiomyopathies. Heart failure with preserved ejection fraction is more often diagnosed in women, who experience better survival after a heart failure diagnosis. Stroke might occur across the lifespan in women, who are at higher risk of stroke-related disability and age-specific mortality. Sex- and gender-unique differences exist in symptoms and pathophysiology of CVD in women. These differences must be considered when evaluating CVD manifestations, because they affect management and prognosis of cardiovascular conditions in women.

Caregiver Health-Related Quality of Life, Burden, and Patient Outcomes in Ambulatory Advanced Heart Failure: A Report From REVIVAL

Background Heart failure (HF) imposes significant burden on patients and caregivers. Longitudinal data on caregiver health-related quality of life (HRQOL) and burden in ambulatory advanced HF are limited. Methods and Results Ambulatory patients with advanced HF (n=400) and their participating caregivers (n=95) enrolled in REVIVAL (Registry Evaluation of Vital Information for VADs [Ventricular Assist Devices] in Ambulatory Life) were followed up for 24 months, or until patient death, left ventricular assist device implantation, heart transplantation, or loss to follow-up. Caregiver HRQOL (EuroQol Visual Analog Scale) and burden (Oberst Caregiving Burden Scale) did not change significantly from baseline to follow-up. At time of caregiver enrollment, better patient HRQOL by Kansas City Cardiomyopathy Questionnaire was associated with better caregiver HRQOL (P=0.007) and less burden by both time spent (P<0.0001) and difficulty (P=0.0007) of caregiving tasks. On longitudinal analyses adjusted for baseline values, better patient HRQOL (P=0.034) and being a married caregiver (P=0.016) were independently associated with better caregiver HRQOL. Patients with participating caregivers (versus without) were more likely to prefer left ventricular assist device therapy over time (odds ratio, 1.43; 95% CI, 1.03-1.99; P=0.034). Among patients with participating caregivers, those with nonmarried (versus married) caregivers were at higher composite risk of HF hospitalization, death, heart transplantation or left ventricular assist device implantation (hazard ratio, 2.99; 95% CI, 1.29-6.96; P=0.011). Conclusions Patient and caregiver characteristics may impact their HRQOL and other health outcomes over time. Understanding the patient-caregiver relationship may better inform medical decision making and outcomes in ambulatory advanced HF.

Exploring gender differences in trajectories of clinical markers and symptoms after left ventricular assist device implantation

AIMS

Despite well-known gender differences in heart failure, it is unknown if clinical markers and symptoms differ between women and men after left ventricular assist device (LVAD) implantation. Our aim was to examine gender differences in trajectories of clinical markers (echocardiographic markers and plasma biomarkers) and symptoms from pre- to post-LVAD implantation.

METHODS AND RESULTS

This was a secondary analysis of data collected from a study of patients from pre- to 1, 3, and 6 months post-LVAD implantation. Data were collected on left ventricular internal end-diastolic diameter (LVIDd) and ejection fraction (LVEF), plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP), and soluble suppressor of tumorigenicity (sST2). Physical and depressive symptoms were measured using the Heart Failure Somatic Perception Scale and Patient Health Questionnaire-9, respectively. Latent growth curve modelling was used to compare trajectories between women and men. The average age of the sample (n = 98) was 53.3 ± 13.8 years, and most were male (80.6%) and had non-ischaemic aetiology (65.3%). Pre-implantation, women had significantly narrower LVIDd (P < 0.001) and worse physical symptoms (P = 0.041) compared with men. Between pre- and 6 months post-implantation, women had an increase in plasma sST2 followed by a decrease, whereas men had an overall decrease (slope: P = 0.014; quadratic: P = 0.011). Between 1 and 6 months post-implantation, women had a significantly greater increase in LVEF (P = 0.045) but lesser decline in plasmoa NT-proBNP compared with men (P = 0.025).

CONCLUSION

Trajectories of clinical markers differed somewhat between women and men, but trajectories of symptoms were similar, indicating some physiologic but not symptomatic gender differences in response to LVAD.

Palliative Care for People Living With Heart Disease-Does Sex Make a Difference?

The distribution of individual heart disease differs among women and men and, parallel to this, among particular age groups. Women are usually affected by cardiovascular disease at an older age than men, and as the prevalence of comorbidities (like diabetes or chronic pain syndromes) grows with age, women suffer from a higher number of symptoms (such as pain and breathlessness) than men. Women live longer, and after a husband or partner's death, they suffer from a stronger sense of loneliness, are more dependent on institutionalized care and have more unaddressed needs than men. Heart failure (HF) is a common end-stage pathway of many cardiovascular diseases and causes substantial symptom burden and suffering despite optimal cardiologic treatment. Modern, personalized medicine makes every effort, including close cooperation between disciplines, to alleviate them as efficiently as possible. Palliative Care (PC) interventions include symptom management, psychosocial and spiritual support. In complex situations they are provided by a specialized multiprofessional team, but usually the application of PC principles by the healthcare team responsible for the person is sufficient. PC should be involved in usual care to improve the quality of life of patients and their relatives as soon as appropriate needs emerge. Even at less advanced stages of disease, PC is an additional layer of support added to disease modifying management, not only at the end-of-life. The relatively scarce data suggest sex-specific differences in symptom pathophysiology, distribution and the requisite management needed for their successful alleviation. This paper summarizes the sex-related differences in PC needs and in the wide range of interventions (from medical treatment to spiritual support) that can be considered to optimally address them.

Sex differences in eligibility for advanced heart failure therapies

OBJECTIVES

We investigated sex-based differences in eligibility for and outcomes after receipt of advanced heart failure (HF) therapies.

BACKGROUND

Although women are more likely to die from HF than men, registry data suggest that women are less likely to receive heart transplant (HT) or left ventricular assist device (LVAD) for largely unknown reasons.

METHODS

We performed a single-center retrospective cohort study of patients evaluated for advanced HF therapies from 2012 to 2016. Logistic regression was used to determine the association of sex with eligibility for HT/LVAD. Competing risks and Kaplan-Meier analysis were used to examine survival.

RESULTS

Of 569 patients (31% women) evaluated, 223 (39.2%) were listed for HT and 81 (14.2%) received destination (DT) LVAD. Women were less likely to be listed for HT (adjusted odds ratio [OR] 0.36, 95% confidence interval [CI] 0.21-0.61; P < .0001), based on allosensitization (P < .0001) and obesity (P = .02). Women were more likely to receive DT LVAD (adjusted OR 2.29, 95% CI 1.23-4.29; P = .01). Survival was similar between men and women regardless of whether they received HT and DT LVAD or were ineligible for therapy.

CONCLUSION

Women are less likely to be HT candidates, but more likely to receive DT LVAD.
