Gender differences in quality of life are minimal in patients with heart failure

Sex differences in the impact of physical frailty on outcomes in heart failure

BACKGROUND

Physical frailty is strongly related to adverse outcomes in heart failure (HF), and women are more likely to be physically frail than men; however, it is unknown if this sex difference affects outcomes.

OBJECTIVES

To determine if there are sex differences in the associations between physical frailty and health-related quality of life (HRQOL) and clinical outcomes in HF.

METHODS

We conducted a prospective study of adults with HF. Physical frailty was assessed using the Frailty Phenotype Criteria. HRQOL was assessed using the Minnesota Living with HF Questionnaire. One-year clinical events (all-cause death or cardiovascular hospitalization or emergency department visit) were ascertained. We used generalized linear modeling to quantify associations between physical frailty and HRQOL, and Cox proportional hazards modeling to quantify associations between physical frailty and clinical events, adjusting for Seattle HF Model scores.

RESULTS

The sample (n = 115) was 63.5 ± 15.7 years old and 49% women. Physical frailty was associated with significantly worse total HRQOL among women (p = 0.005) but not men (p = 0.141). Physical frailty was associated with worse physical HRQOL among both women (p < 0.001) and men (p = 0.043). There was a 46% higher clinical event risk for every one-point increase in physical frailty score among men (p = 0.047) but not women (p = 0.361).

CONCLUSIONS

Physical frailty is associated with worse overall HRQOL among women and higher clinical event risk among men, indicating a need to better understand contributors to sex-specific health differences associated with physical frailty in HF.

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.

Quality of life of chronic heart failure patients: a systematic review and meta-analysis

Despite various individual studies on the quality of life (QOL) in patients with CHF, a comprehensive study has not yet been conducted; therefore, this study aims to assess the QOL of CHF patients. In the present systematic review and meta-analysis, PubMed, Scopus, and the Web of science databases were searched from January 1, 2000, to December 31, 2018, using QOL and heart failure as keywords. The searches, screenings, quality assessments, and data extractions were conducted separately by two researchers. A total of 70 studies including 25,180 participants entered the final stage. The mean QOL score was 44.1 (95% confidence interval (CI) 40.6, 47.5; I² = 99.3%) using a specific random effects method in 40 studies carried out on 12,520 patients. Moreover, according to the geographical region, heart failure patients in the Americas had higher scores. In 14 studies, in which a general SF-36 survey was implemented, the average physical component score (PCS) and mental component score (MCS) were 33.3 (95% CI 31.9, 34.7; I² = 88.0%) and 50.6 (95% CI 43.8, 57.4; I² = 99.3%), respectively. The general and specific tools used in this study indicated moderate and poor QOL, respectively. Therefore, it is necessary to carry out periodic QOL measurements using appropriate tools as part of the general care of CHF patients.

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.

Assessment of quality of life and anxiety in heart failure outpatients

Introduction

Heart failure (HF) is a chronic disease associated with increased morbidity and mortality. HF prevalence is expected to expand enormously, largely due to population ageing, rising incidence of HF risk factors and increased survival after cardiovascular events. The aim of the study was to assess levels of quality of life (QOL) and anxiety in HF outpatients and the associated factors as well as to explore the impact of anxiety on QOL.

Material and methods

One hundred HF outpatients were enrolled in the study. Data collection was performed by completion of the Minnesota Living with Heart Failure Questionnaire (MLHFQ), the Self-rating Anxiety Scale (SAS) and a questionnaire including patients’ characteristics.

Results

Of the 100 HF outpatients, 64% were men and 66% above 70 years old. Regarding QOL, at least 50% of patients scored above 68 (median) in the total score of MLHFQ and in terms of anxiety, 50% scored above 46 (median) in the SAS. These values indicate a large impact of HF on QOL and a moderate impact of HF on anxiety. Furthermore, a statistically significant correlation was observed between QOL and anxiety in HF outpatients (rho > 0.6, p < 0.001). An increase in anxiety score by one unit implies a statistically significant increase in QOL by 1.22 points (95% CI: 0.91–1.52, p < 0.001), after adjustment for potential confounders.

Conclusions

The present findings emphasize the importance of alleviating the emotional burden of anxiety, thus improving patients’ QOL.

Relationship of medication adherence and quality of life among heart failure patients

BACKGROUND

Little is known regarding the relationship between medication adherence and quality of life in heart failure patients. We therefore aimed to examine the nature of relationship between medication adherence and quality of life.

METHODS

A prospective, cross-sectional study of chronic heart failure patients with reduced ejection fraction was performed at a tertiary-care, university hospital in Thailand. Quality of life and medication adherence were assessed using the Minnesota Living with Heart Failure Questionnaire (MLHFQ) and Morisky Medication Adherence Scale-8 (MMAS-8), respectively. Relationship of MLHFQ and MMAS-8 were examined using Spearman's correlation coefficient and multiple regression analysis for covariates adjustment.

RESULTS

Among 180 patients, 38.3%, 50.0% and 11.7% were found to have high, medium and poor adherence, respectively. For quality of life, the overall median score on the MLHFQ was relatively low. A positive relationship was identified between medication adherence and quality of life. After covariate adjustment, medication adherence was found to have the strongest relationship with quality of life, compared to other covariates.

CONCLUSIONS

Medication adherence has a small and positive relationship with quality of life among heart failure patients.

Health Status Disparities by Sex, Race/Ethnicity, and Socioeconomic Status in Outpatients With Heart Failure

OBJECTIVES

This study sought to describe the health status of outpatients with heart failure and reduced ejection fraction (HFrEF) by sex, race/ethnicity, and socioeconomic status (SES).

BACKGROUND

Although a primary goal in treating patients with HFrEF is to optimize health status, whether disparities by sex, race/ethnicity, and SES exist is unknown.

METHODS

In the CHAMP-HF (Change the Management of Patients with Heart Failure) registry, the associations among sex, race, and SES and health status, as measured by the Kansas City Cardiomyopathy Questionnaire-overall summary (KCCQ-os) score (range 0 to 100; higher scores indicate better health status) was compared among 3,494 patients from 140 U.S. clinics. SES was categorized by total household income. Hierarchical multivariate linear regression estimated differences in KCCQ-os score after adjusting for 31 patient characteristics and 10 medications.

RESULTS

Overall mean KCCQ-os scores were 64.2 ± 24.0 but lower for women (29% of sample; 60.3 ± 24.0 vs. 65.9 ± 24.0, respectively; p < 0.001), for blacks (60.5 ± 25.0 vs. 64.9 ± 23.0, respectively; p < 0.001), for Hispanics (59.1 ± 21.0 vs. 64.9 ± 23.0, respectively; p < 0.001), and for those with the lowest income (<$25,000; mean: 57.1 vs. 63.1 to 74.7 for other income categories; p < 0.001). Fully adjusted KCCQ-os scores were 2.2 points lower for women (95% confidence interval [CI]: -3.8 to -0.6; p = 0.007), no different for blacks (p = 0.74), 4.0 points lower for Hispanics (95% CI: -6.6 to -1.3; p = 0.003), and lowest in the poorest patients (4.7 points lower than those with the highest income (95% CI: 0.1 to 9.2; p = 0.045; p for trend = 0.003).

CONCLUSIONS

Among outpatients with HFrEF, women, blacks, Hispanics, and poorer patients had worse health status, which remained significant for women, Hispanics, and poorer patients in fully adjusted analyses. This suggests an opportunity to further optimize treatment to reduce these observed disparities.

Direction of the Relationship Between Acceptance of Illness and Health-Related Quality of Life in Chronic Heart Failure Patients

BACKGROUND

This study provides an in-depth insight into the relationships between illness acceptance and health-related quality of life (HRQoL) of chronic heart failure (CHF) patients. Although HRQoL is a well-established endpoint in CHF, little is known on illness acceptance in this group.

AIMS

The aim of this study is to critically reconsider the direction of a relationship between HRQoL and illness acceptance in CHF patients.

METHODS

The study included 204 patients (160 men and 44 women; mean age, 63 ± 11 years) with at least 6-month clinical evidence of CHF corresponding to New York heart Association (NYHA) classes I to IV. All the patients were examined with the Minnesota Living With Heart Failure Questionnaire (MLHFQ) and Acceptance of Illness Scale (AIS).

RESULTS

Univariate analysis showed that the level of illness acceptance correlated inversely with patient age, and the level of HRQoL decreased with the severity of CHF (NYHA class). A relationship between illness acceptance and HRQoL was analyzed by structural equation modeling. Model 1 was based on the assumption that HRQoL is modulated by illness acceptance, and model 2 tested the opposite relationship. Both models included patient age and NYHA class as extrinsic determinants of AIS and MLHFQ scores, respectively. Model 2 proved to be well fitted (χ [df = 2] = 3.22, P = .20, root-mean-square error of approximation = 0.055). Scores on the AIS correlated inversely with age (bage->AIS = -0.15, SE = 0.05, P = .002) and HRQoL (bQoL->AIS = -0.15, SE = 0.02, P < .001), and an increase in NYHA class was reflected by an increase in HRQoL scores (bNYHA->QoL = 5.75, SE = 1.97, P = .004).

CONCLUSION

Patients with CHF may not accept their disease due to deteriorated HRQoL. As a result, they may be uninvolved in the therapeutic process, which leads to exacerbation of CHF, further deterioration of HRQoL, and inability to accept the illness.

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.

Patient factors associated with quality of life in atrial fibrillation

BACKGROUND

As treatment options for atrial fibrillation (AF) increase, more attention is focused on patients' experiences and quality of life (QoL). However, little is known about the factors associated with these outcomes.

METHODS

The Atrial Fibrillation Effect on QualiTy-of-life (AFEQT) is a disease-specific QoL tool for AF, with domain and summary scores ranging from 0 (the worst QoL) to 100. Using multivariable linear regression, we evaluated factors associated with baseline AFEQT Summary and Subscale Scores in ORBIT AF, a large, community-based AF registry. Independent associations were reported as coefficient estimates in scores and 95% confidence intervals (CI).

RESULTS

Overall, AFEQT was assessed in 2007 AF outpatients from 99 sites. Median age (IQR) was 76 years (67-82) and 43% were female. The median AFEQT summary score was 82 (67-94). Female sex, younger age, new onset AF, higher heart rate, obstructive sleep apnea, symptomatic heart failure (HF), chronic obstructive pulmonary disease and coronary artery disease were all independently associated with reduced QoL. Female sex [Estimate -7.03, 95% CI (-9.31, -4.75)] and new onset versus permanent AF [Estimate -7.44, 95% CI (-11.03, -3.84)] were independently associated with increased symptoms. NYHA Class III or IV HF [Estimate -14.44, 95% CI (-19.46, -8.76)] and female sex [Estimate -7.91, 95% CI (-9.95, -5.88)] were most independently associated with impaired daily activities.

CONCLUSIONS

QoL in patients with AF varies widely and is associated with several patient factors. Understanding patient factors independently associated with worse QoL can be a foundation for tailoring treatment.

Self-efficacy and depression predicting the health-related quality of life of outpatients with chronic heart failure in Singapore

BACKGROUND

Chronic heart failure (CHF) remains as a debilitating disease that has high mortality among adults worldwide. CHF negatively impacts an individual's health-related quality of life (HRQoL), but only few studies have investigated such an impact in the Asian population.

AIMS

This study aims to investigate the HRQoL of outpatients with CHF and identify its predictors among this group of patients in Singapore.

METHODS

This was a cross-sectional, descriptive correlational study. A convenience sampling of 121 outpatients with CHF was recruited from a public hospital over 5 months. The Minnesota Living with Heart Failure Questionnaire (MLHFQ), Short Form-Cardiac Depression Scale, Cardiac Self-Efficacy Scale, and Medical Outcomes Study Social Support Survey were used to measure the study variables.

RESULTS

There were significant differences in the HRQoL as assessed using the MLHFQ between gender, educational level, and primary caregiver status (p<0.05). Self-efficacy (β=0.637, p<0.001) and depression (β=-0.220, p<0.001) were found to be the predictors of the HRQoL in outpatients with CHF, accounting for 67.9% of variance.

CONCLUSION

The results of the study indicated that lower levels of self-efficacy and depression predicted poor HRQoL. Nursing care should focus on detecting depressive symptoms in patients with CHF. A program facilitating better self-care is important in CHF management.

Factors and Interventions Influencing Health-Related Quality of Life in Patients with Heart Failure: A Review of the Literature

INTRODUCTION

Because of the lack of a cure for patients with chronic heart failure (HF), there has been a progressive interest in the use of health-related quality of life (Hr-QoL) as complementary end-point to mortality and morbidity.

AIM

The aim of this review was from a nursing perspective to describe Hr-QoL and the influencing factors of Hr-QoL, as well as to identify interventions aimed at influencing Hr-QoL in HF patients.

METHOD

Medline, Cinahl and PsycInfo databases were searched from 1995 to 2004. A total of 58 papers were included.

RESULTS

HF symptoms and activity status influence Hr-QoL negatively. However, several individual characteristics such as personality, gender and age must also be taken into consideration because different values might exist regarding what constitutes a good Hr-QoL. Nurse led interventions based on education, support and exercise can influence Hr-QoL positively. There is also a need of more studies about the effects of depression, sleep disturbances, support as well as education on Hr-QoL. There is also a need of exercise studies with larger sample sizes and older patients in higher NYHA classes.

CONCLUSION

Several individual factors impact Hr-QoL, therefore, must nursing interventions are individually adapted to the patient's resources.

Gender Differences in the Effects of Physical and Emotional Symptoms on Health-Related Quality of Life in Patients with Heart Failure

BACKGROUND

Physical and emotional symptoms are common in heart failure. These symptoms are theorized to affect health-related quality of life (HRQOL), but their impact is likely mediated by variables not yet explored. Moreover, gender may affect these relationships.

AIM

To determine gender differences in the effects of physical and emotional symptom status on HRQOL.

METHODS AND RESULTS

Data from 51 men and 47 women with heart failure were analyzed using regression analyses. There were no gender differences in physical or emotional symptom status, or HRQOL, but there were differences in the dynamic relationships among the variables. In bivariate analyses, physical and emotional symptom status was related to HRQOL in both men and women. However, in women, physical symptom status was related to HRQOL, while in men depression affected HRQOL in multivariate analyses (p<.001, r(2)=.27; p<.001, r(2)=.40, respectively). Functional status measured by the New York Heart Association functional class mediated the effects of anxiety and depression on HRQOL only in women.

CONCLUSION

There were gender differences in the dynamic relationships among variables related to HRQOL. These results demonstrate the need for individualized, comprehensive evaluation of patient's HRQOL and symptom status in order to appropriately target interventions.

Predictors for Health Related Quality of Life in Persons 65 Years or Older with Chronic Heart Failure

BACKGROUND

A main goal in nursing care of persons with chronic heart failure (HF) is to strengthen their health related quality of life (HRQoL). This presupposes knowledge about the relation between heart failure and HRQoL. Existing studies have shown incongruent results about whether HRQoL is affected differently depending on age or sex of elderly persons with chronic HF.

AIM

This study aimed to investigate if age, sex, disease severity, comorbidity and living conditions predict health related quality of life among persons 65 years or older with chronic HF.

METHODS

The study included a sample of 357 persons. HRQoL was measured by the Minnesota Living with Heart Failure Questionnaire and the Short Form-12 Health Survey Questionnaire. Multiple regression analyses were performed to analyse the relation between the predictors and HRQoL.

RESULTS

The main finding was that self-rated disease severity was strongly associated with HRQoL, but also age, sex, diabetes and respiratory diseases was associated with some of the dimensions of HRQoL.

CONCLUSIONS

Interventions aimed at delaying the progress of the disease, assist persons' to cope with the disease and maintain the domains of HRQoL that are still feasible could be important to improve HRQoL in elderly persons with chronic HF.

'It could be worse ... lot's worse!' Why health-related quality of life is better in older compared with younger individuals with heart failure

BACKGROUND

health-related quality of life (HRQOL) is markedly impaired in patients with heart failure (HF). Despite worse prognosis and physical status, older patients have better HRQOL than younger patients.

OBJECTIVE

to determine reasons for differences in HRQOL in older compared with younger HF patients.

METHODS

a mixed methods approach was used. HRQOL was assessed using the Minnesota Living with HF Questionnaire and compared among HF patients (n = 603) in four age groups (≤ 53, 54-62, 63-70 and ≥ 71 years). Socio-demographic/clinical and psychological factors related to HRQOL were determined in four groups using multiple regressions. Patients (n = 20) described their views of HRQOL during semi-structured interviews.

RESULTS

HRQOL was worse in the youngest group, and best in the two oldest groups. The youngest group reported higher levels of depression and anxiety than the oldest group. Anxiety, depression and functional capacity predicted HRQOL in all age groups. Qualitatively, patients in all age groups acknowledged the negative impact of HF on HRQOL; nonetheless older patients reported that their HRQOL exceeded their expectations for their age. Younger patients bemoaned the loss of activities and roles, and reported their HRQOL as poor.

CONCLUSIONS

better HRQOL among older HF patients is the result, in part, of better psychosocial status. The major factor driving better HRQOL among older patients is a change with advancing age in expectations about what constitutes good HRQOL.

Commonalities and differences in correlates of depressive symptoms in men and women with heart failure

OBJECTIVE

(i) To compare the prevalence and severity of depressive symptoms between men and women enrolled in a large heart failure (HF) registry. (ii) To determine gender differences in predictors of depressive symptoms from demographic, behavioral, clinical, and psychosocial factors in HF patients.

METHODS

In 622 HF patients (70% male, 61 ± 13 years, 59% NYHA class III/IV), depressive symptoms were assessed by the Patient Health Questionnaire (PHQ-9). Potential correlates were age, ethnicity, education, marital and financial status, smoking, exercise, body mass index (BMI), HF etiology, NYHA class, comorbidities, functional capacity, anxiety, and perceived control. To identify gender-specific correlates of depressive symptoms, separate logistic regression models were built by gender.

RESULTS

Correlates of depressive symptoms in men were financial status (p = 0.027), NYHA (p = 0.001); functional capacity (p < 0.001); health perception (p = 0.043); perceived control (p = 0.002) and anxiety (p < 0.001). Correlates of depressive symptoms in women were BMI (p = 0.003); perceived control (p = 0.013) and anxiety (p < 0.001).

CONCLUSIONS

In HF patients, lowering depressive symptoms may require gender-specific interventions focusing on weight management in women and improving perceived functional capacity in men. Both men and women with HF may benefit from anxiety reduction and increased control.

Comparison of health-related quality of life between American and Taiwanese heart failure patients

Few investigators have compared health-related quality of life (HRQOL) in heart failure (HF) patients from different countries.The purposes of this study were to compare HRQOL between American (n = 87) and Taiwanese (n = 88) HF patients and to determine factors associated with HRQOL in both groups. In this cross-sectional survey, HRQOL was measured using the Minnesota Living with Heart Failure Questionnaire. American patients rated their HRQOL worse than Taiwanese patients did. Sociodemographics, disease severity, and symptom severity were associated with HRQOL, accounting for 42.4% of the variance in HRQOL in Americans and 57.3% in Taiwanese. Symptom severity was the most important predictor of HRQOL in both groups. Interventions targeting symptom severity could improve HF patients' HRQOL.

Improvements in health-related quality of life of patients admitted for heart failure. The HF-QoL study

INTRODUCTION AND OBJECTIVES

Heart failure (HF) is associated with a poor prognosis, both in terms of survival and ongoing symptoms. The objectives of this study were to investigate trends in the health-related quality of life (HRQoL) of a heterogeneous group of HF patients, with a focus on subgroups of particular clinical interest, and to identify determinants of mortality.

METHODS

Prospective study of 883 HF patients discharged from 50 Spanish hospitals and followed for 1 year, during which six HRQoL assessments were carried out using the generic Short Form-36 (SF-36) questionnaire and the specific Minnesota Living with Heart Failure Questionnaire (MLHFQ).

RESULTS

A marked change was noted at the beginning of the study on all dimensions of the SF-36, in its physical (mean 34.1) and mental (mean 40.1) component summary scores, and in the MLHFQ score (mean 37.5). There was a clear improvement in the first month, which subsequently remained unchanged, except in younger patients aged under 40 years whose HRQoL continued to improve progressively. The following predictors of mortality were identified: age, functional class, co-morbidity and baseline HRQoL.

CONCLUSIONS

In patients with HF, HRQoL showed a clear improvement during the first month after hospital discharge but subsequently remained unchanged, except in younger patients, whose HRQoL continued to improve progressively.

Explanation of the variance in quality of life and activity capacity of patients with heart failure by laboratory data

BACKGROUND

This study was conducted to explain the variance in quality of life (QoL) and activity capacity of patients with congestive heart failure from pathophysiological changes as estimated by laboratory data.

METHODS

Peak oxygen consumption (peak VO2) and ventilation (VE)/carbon dioxide output (VCO2) slope derived from cardiopulmonary exercise testing, plasma N-terminal prohormone of B-type natriuretic peptide (NT-proBNP), and echocardiographic markers [left atrium (LA), left ventricular ejection fraction (LVEF)] were measured in 62 patients with congestive heart failure, who also completed the Minnesota Living with Heart Failure Questionnaire and the Specific Activity Questionnaire. All regression models were adjusted for age and sex.

RESULTS

On linear regression analysis, peak VO2 with P value less than 0.001, VE/VCO2 slope with P value less than 0.01, LVEF with P value less than 0.001, LA with P=0.001, and logNT-proBNP with P value less than 0.01 were found to be associated with QoL. On stepwise multiple linear regression, peak VO2 and LVEF continued to be predictive, accounting for 40% of the variability in Minnesota Living with Heart Failure Questionnaire score. On linear regression analysis, peak VO2 with P value less than 0.001, VE/VCO2 slope with P value less than 0.001, LVEF with P value less than 0.05, LA with P value less than 0.001, and logNT-proBNP with P value less than 0.001 were found to be associated with activity capacity. On stepwise multiple linear regression, peak VO2 and LA continued to be predictive, accounting for 53% of the variability in Specific Activity Questionnaire score.

CONCLUSION

Peak VO2 is independently associated both with QoL and activity capacity. In addition to peak VO2, LVEF is independently associated with QoL, and LA with activity capacity.

Quality of life in patients with heart failure: ask the patients

BACKGROUND

Heart failure (HF) is a progressive clinical condition that results in substantial impairment of quality of life (QOL). Helping patients maintain optimal QOL is essential. QOL reflects patients' subjective perceptions about the impact of a clinical condition and its treatment on daily life; however, definitions in the literature vary widely and few reflect the patient's perspective.

PURPOSE

The study explored how patients with HF define and perceive QOL.

METHODS

Qualitative data were obtained from 14 men and 6 women with HF (mean age 58 +/- 10 years) using semistructured open-ended interviews. The interviews were analyzed using content analysis.

RESULTS

Patients with HF defined QOL as their ability to 1) perform desired physical and social activities to meet their and their family's needs; 2) maintain happiness; and 3) engage in fulfilling relationships with others. Patients perceived a variety of factors as positively or negatively affecting QOL: physical (symptoms and good or poor physical status), psychologic (mood and positive or negative perspective), economic (financial status), social (social support and ability for social activities), spiritual, and behavioral (self-care). Patients perceived that HF had a serious impact on QOL, but most evaluated their QOL as good nonetheless.

CONCLUSION

Patients' definition of QOL reflected not only the impact of HF on their daily life but also their active pursuit of happiness. Patients' self-evaluation of QOL reflected the negative impact of HF and patients' altered expectations of what constituted good QOL.

Depression is a major determinant of quality of life in patients with chronic systolic heart failure in general practice

BACKGROUND

Quality of life (QoL) is severely restricted in patients with chronic heart failure (CHF). Patients frequently suffer from depressive comorbidity. It is not clear, to what extent sociodemographic variables, heart failure severity, somatic comorbidities and depression determine QoL of patients with CHF in primary care.

METHODS AND RESULTS

In a cross-sectional analysis, 167 patients, 68.2 +/- 10.1 years old, 68.9% male, New York Heart Association (NYHA) functional class II-IV, Left ventricular ejection fraction (LVEF) < or = 40%, were recruited in their general practitioner's practices. Heart failure severity was assessed with echocardiography and N-terminal brain natriuretic peptide (NT-proBNP); multimorbidity was assessed with the Cumulative Illness Rating Scale (CIRS-G). QoL was measured with the Short Form 36 Health Survey (SF-36) and depression with the depression module of the Patient Health Questionnaire (PHQ-9). Significant correlations with all SF-36 subscales were only found for the CIRS-G (r = -0.18 to -0.36; P < .05) and the PHQ-9 (r = -0.26 to -0.75; P < .01). In multivariate forward regression analyses, the PHQ-9 summary score explained the most part of QoL variance in all of the SF-36 subscales (r2 = 0.17-0.56). LVEF and NT-proBNP did not have significant influence on QoL.

CONCLUSIONS

Depression is a major determinant of quality of life in patients with chronic systolic heart failure, whereas somatic measures of heart failure severity such as NT-proBNP and LVEF do not contribute to quality of life. Correct diagnosis and treatment of depressive comorbidity in heart failure patients is essential.

Computer-based education for patients with chronic heart failure. A randomised, controlled, multicentre trial of the effects on knowledge, compliance and quality of life

OBJECTIVE

To evaluate the effects of a single-session, interactive computer-based educational program on knowledge, compliance and quality of life in heart failure patients with special emphasis on gender differences.

METHODS

One hundred and fifty-four patients, mean age 70 years, from five heart failure clinics were randomised to either receiving only standard education (n=72) or standard education and additional computer-based education (n=82).

RESULTS

Knowledge was increased in both groups after 1 month with a trend towards higher knowledge (P=0.07) in the computer-based group. The increase in knowledge was significantly higher in the computer-based group after 6 months (P=0.03). No differences were found between the groups with regard to compliance with treatment and self-care or quality of life. The women had significantly lower quality of life and did not improve after 6 months as the men did (P=0.0001).

CONCLUSION

Computer-based education gave increased knowledge about heart failure.

PRACTICE IMPLICATIONS

Computers can be a useful tool in heart failure education, but to improve compliance a single-session educational intervention is not sufficient. Gender differences in learning and quality of life should be further evaluated.

Relationships between clinical assessments and patients' perceptions of the effects of heart failure on their quality of life

BACKGROUND

Hypothetically, most of the effects of heart failure on quality of life might be attributed to symptoms produced by the pathology. Relationships between measures of these concepts need to be quantified to test this conceptual model.

METHODS AND RESULTS

Measurements of heart failure pathology and symptoms and quality of life as measured by the Minnesota Living with Heart Failure (MLHF) questionnaire at the 4-month visit in the Valsartan Heart Failure Trial were analyzed. Correlation and regression analyses corrected for estimated reliability of measurements were used to quantify relationships. The percentage of variance in dependent variables that was related to explanatory variables was summarized by the coefficient of determination (100 xR(2)) from regression models. Dyspnea at rest, dyspnea on exertion, paroxysmal nocturnal dyspnea, orthopnea, fatigue, and New York Heart Association class were significantly related to MLHF scores. Combined, these symptoms explained 41% of the variation in MLHF scores. Controlling for symptoms, age explained an additional 4.5% of the variation in MLHF scores, whereas race, gender, and available comorbidities each explained <1%. Pathologic measures including ejection fraction, B-type natriuretic peptide, jugular venous distension, rales, peripheral edema, systolic blood pressure, creatinine, and hemoglobin were not strongly related to symptom assessments (combined R(2) = 17%) or MLHF scores (combined R(2) = 7%).

CONCLUSION

Symptoms of heart failure explain a substantial proportion of the variation in the effects of heart failure on patients' quality of life as measured by the MLHF score. The effects of heart failure on quality of life can vary with age independently of symptoms. Pathologic measures of heart failure including some well-known correlates of the risk of hospitalization and death are not strongly related to symptoms or quality of life. Further studies are needed to understand the relationships between heart failure pathology and symptoms and to identify determinants of the effects of heart failure on patients' quality of life that were not related to symptoms.

Predictors of the quality of life of older people with heart failure recruited from primary care

BACKGROUND

Current understanding of quality of life in heart failure is largely derived from clinical trials. Older people, women and those with co-morbidities are underrepresented in these. Little is known about factors predictive of quality of life amongst older people with heart failure recruited from community settings.

OBJECTIVE

To identify factors predictive of quality of life amongst older people recruited from community settings.

DESIGN

prospective questionnaire survey.

SETTING

General practice surgeries located in four areas of the UK: Bradford, Barnsley, East Devon and West Hampshire.

SUBJECTS

A total of 542 people aged >60 years with heart failure.

METHODS

Participants completed a postal questionnaire, which included a disease-specific measure (Kansas City Cardiomyopathy Questionnaire), a generic quality-of-life measure (SF-36) and sociodemographic information.

RESULTS

A multiple linear regression analysis identified the following factors as predictive of decreased quality of life: being female, being in New York Heart Association (NYHA) functional class III or IV, showing evidence of depression, being in socioeconomic groups III-V and experiencing two or more co-morbidities. Older age was associated with decreased quality of life, as measured by a generic health-related quality-of-life tool (the SF-36 mental and physical health functioning scales) but not by a disease-specific tool (the Kansas City Cardiomyopathy Questionnaire).

CONCLUSION

Findings from the study suggest that quality of life for older people with heart failure can be described as challenging and difficult, particularly for women, those in a high NYHA class, patients showing evidence of depression, patients in socioeconomic groups III-V, those experiencing two or more co-morbidities and the 'oldest old'. Such information can help clinicians working with older people identify those at risk of reduced quality of life and target interventions appropriately.

Impact of symptom prevalence and symptom burden on quality of life in patients with heart failure

BACKGROUND

Heart failure is an escalating health problem around the world. Despite significant scientific advances, heart failure patients experience multiple physical and psychological symptoms that can impact the quality of life.

AIMS

To determine the (1) symptom prevalence, severity, distress and symptom burden in patients with heart failure; (2) impact of age and gender on symptom prevalence, severity, distress and symptom burden; and (3) impact of symptom prevalence and symptom burden on health-related quality of life (HRQOL) in patients with heart failure.

METHODS

A convenience sample of 53 heart failure patients participated in this descriptive, cross-sectional design. Symptoms and HRQOL were measured using the Memorial Symptom Assessment Scale-Heart Failure and the Minnesota Living with Heart Failure Questionnaire.

RESULTS

Patients experienced a mean of 15.1+/-8.0 symptoms. Shortness of breath and lack of energy were the most prevalent. Difficulty sleeping was the most burdensome symptom. Lower age, worse functional status, total symptom prevalence and total symptom burden predicted 67% of the variance in HRQOL.

CONCLUSION

Patients with heart failure experience a high level of symptoms and symptom burden. Nurses should target interventions to decrease frequency, severity, distress and overall symptom burden and improve HRQOL.

The meaning of patient participation for patients and nurses at a nurse-led clinic for chronic heart failure

BACKGROUND

The legislation of many Western countries emphasizes active patient participation. Patients with chronic heart failure (CHF), however, have experienced participation differently from the general interpretation of legal definitions. Education improves uptake of self-management strategies yet knowledge is lacking about support of patients' own resources in CHF.

AIM

To explore the phenomena of patient participation and non-participation as shown in patient visits to a nurse-led clinic for CHF and as experienced by the patients and nurses.

METHODS

Data triangulation of field notes from participatory observations and texts from narrative interviews with the patients and assigned nurse specialists. Data were analyzed according to the phenomenological hermeneutic tradition.

FINDINGS

Patients' experience of participation and non-participation was interpreted as "Being responsible and accepting responsibility" and "Lacking an equal relationship while being controlled", respectively. Nurses experienced patient participation as "Getting information and security to act" and patient non-participation as "Not accepting".

CONCLUSION

Conflicting values of patients and nurses, which were interpreted with respect to participation and non-participation, presumably might influence patient information and education negatively. The issue of participation should be raised as a means of attaining concordance and to facilitate patient participation with education specifically tailored to the individual patient's needs.

The phenomena of participation and non-participation in health care--experiences of patients attending a nurse-led clinic for chronic heart failure

BACKGROUND

Patient participation is stressed in the health care acts of many western countries yet a common definition of the concept is lacking. The understanding of experiences of patients with chronic heart failure (CHF) who attend nurse-led specialist clinics, a form of care suggested as beneficiary to this group, may promote a better understanding of participation.

AIM

To investigate the meanings of participation and non-participation as experienced by patients living with CHF.

METHODS

Narrative interviews analysed in the phenomenological hermeneutic tradition inspired by Ricoeur where the interpretation is made in the hermeneutic circle, explaining and understanding the experienced phenomena.

FINDINGS

Participation was experienced as to "be confident", "comprehend" and "seek and maintain a sense of control". Non-participation was experienced as to "not understand", "not be in control", "lack a relationship" and "not be accountable". The findings indicate that the experiences of participation and non-participation can change over time and phases of the disease and treatment.

CONCLUSION

The study suggests an extended view on the concept of participation. Patients' experiences of participation in health care can vary and should therefore be an issue for dialogue between nurses and patients with CHF in nurse-led specialist clinics.

Gender and risk of adverse outcomes in heart failure

Congestive heart failure (CHF) is the leading cause of hospitalization in the elderly, and these patients are at high risk for subsequent hospitalization. Whether gender affects the risk of rehospitalization in patients who have CHF is less well understood. We studied a random sample of 1,700 adults who had been hospitalized with CHF (from July 1, 1999 to June 30, 2000) and identified all readmissions through June 30, 2001. We used proportional hazards regression to evaluate whether gender affects the risk of all-cause and CHF-specific rehospitalization, after adjusting for differences in demographic characteristics, health-related behaviors, co-morbid conditions, left ventricular systolic function status, and use of CHF therapies. Among 1,591 adults who had confirmed CHF, 752 were women (47.3%). Women were older than men (73 vs 71 years, p <0.001) and more likely to have preserved systolic function (55.3% vs 40.9%, p <0.001), hypertension (83.1% vs 75.2%, p <0.001), and prior renal insufficiency (46.8% vs 34.6%, p <0.001). No significant differences existed between women and men with respect to crude rates of any readmission (144.7 vs 134.6 per 100 person-years, p = 0.36) or CHF-specific readmission (39.9 vs 37.4 per 100 person-years, p = 0.65). After adjusting for potential confounders, there was no significant difference between women and men with respect to risk of any readmission (adjusted hazard ratio 0.88, 95% confidence interval 0.76 to 1.02) or readmission for CHF (adjusted hazard ratio 0.89, 95% confidence interval 0.71 to 1.11). Among a contemporary, diverse population of patients who had CHF, rates of readmission overall and for CHF remained high, but gender was not independently associated with a differential risk of readmission.

State of the Science for Cardiovascular Nursing Outcomes

The incidence of heart failure is increasing because of the progressive aging of the population and improved survival from cardiovascular disease. This article synthesizes the state of the science of nurse sensitive outcomes in heart failure treated medically or surgically and provides recommendations for building the science. Outcomes studied include mortality, morbidity, resource use, quality of life, symptoms, physical function, return to work, and self-care and compliance behavior. Gaps in the literature are identified and recommendations for future research are provided.

Relationship of Age and Sex to Health-Related Quality of Life in Patients With Heart Failure

• Background Although health-related quality of life is diminished among patients with chronic heart failure, few investigators have examined interactions of age and sex with health-related quality of life longitudinally.

• Objectives To examine differences in health-related quality of life among 4 groups of patients with heart failure on the basis of age (&lt;65 years and &gt;65 years) and sex and to evaluate relationships of age and sex to changes in health-related quality of life during 6 months.

• Methods Patients from 2 outpatient clinics in an urban county hospital were interviewed at baseline and 26 weeks later. Health-related quality of life was measured by using the Minnesota Living With Heart Failure Questionnaire and the Chronic Heart Failure Questionnaire.

• Results A total of 165 patients (52% women; mean age, 57.6 years) completed interviews at baseline and 26 weeks later. At baseline, patients younger than 65 years had poorer health-related quality of life scores on total scales and some subscales than did older patients. Women had poorer scores than did men on some scales, particularly the emotional subscales. At 26 weeks, patients younger than 65 had poorer total health-related quality of life on 1 scale than did patients 65 and older, and women had poorer scores than did men on 1 total scale. With demographic and clinical factors controlled for, women younger than 65 had improvements in health-related quality of life on some scales.

• Conclusions Women younger than 65 years had relatively poorer initial health-related quality of life that improved after 26 weeks.

Transitions in Health Status in Older Patients with Heart Failure

BACKGROUND

We aimed to determine transitions in health perception and functional status in older Medicare patients with heart failure.

METHODS

We used 1991 to 1994 data from the Medicare Current Beneficiary Survey, a database that combines Medicare claims with yearly longitudinal surveys. We identified 872 patients 65 years or older in 1991 with a diagnostic code of heart failure.

RESULTS

At baseline, 58% of the patients rated their general health perception as "fair" or "poor." Over 1 year, 18% of the patients died. Transition matrices revealed that health perception, activities of daily living, and instrumental activities of daily living were strong correlates of mortality; that dramatic changes in health status were relatively uncommon over 1 year among survivors; and that decline was common in patients with "excellent" or "very good" health perception. The prior year's health status and comorbidity were powerful predictors of the subsequent year's health status.

CONCLUSION

Many older patients with heart failure have worsening health status over time. Measures of prior health status can help predict chances of functional recovery.
