Learning Objective #1: describe gender differences in health related quality of life for heart failure patients.
Learning Objective #2: describe health-related quality of life for heart failure patients as measured by the Kansas City Cardiomyopathy Questionnaire.

Heart failure (HF) is a chronic disease with an enormous impact on patient’s health-related quality of life. The purpose of this study was to explore gender differences in health-related quality of life for patients with heart failure.  Baseline data was analyzed from a randomized clinical trial with 42 HF patients. Twenty-four subjects were male and 18 were female. Fifty percent of the subjects had ischemic HF and 50% were non-ischemic. Mean age was 61.24 ± 14.35 years and mean left ventricular ejection fraction (LVEF) was 32.86 ± 6.16%. There were no significant differences by gender in age, LVEF or functional status as measured by the 6-minute walk test. The Kansas City Cardiomyopathy Questionnaire (KCCQ) was utilized to measure health-related quality of life. The KCCQ has eight domains each ranging from 0 to 100 with lower scores indicating greater impairment. Independent t-test results showed women had significantly greater impairment [t (df=38) = 2.20, p = .034] in the total symptom score (65.3 ± 23.6) as compared to men (79.2 ± 16.1). Women also had significantly greater impairment [t (df=38) = 2.28, p = .029] in the KCCQ symptom frequency domain (63.0 ± 22.9) as compared to men (77.7 ± 17.8). The only two domain scores of the KCCQ that showed women to have less impairment than men were the quality of life domain [t (df=38) = -.22, p = .826] and the self-efficacy domain [t (df=38) = -1.68, p = .102] and these differences were non-significant. Findings from this study suggest that interventions to improve quality of life in heart failure may need to be gender specific.  Further study is needed to explore differences in health-related quality of life and the symptom experience for men and women with HF.
