Clinical InvestigationMultinational and multiethnic variations in health-related quality of life in patients with chronic heart failure
Section snippets
Methods
For the current analysis, we combined the participants from HF-ACTION (N = 1998) and the ASIAN-HF registry (N = 3699) with left ventricular ejection fraction (EF) ≤35% to form a combined cohort of 5697 patients. The trial design and results of HF-ACTION have been previously reported.12., 13. This multicenter, randomized controlled trial compared the long-term safety and efficacy of exercise training plus evidence-based HF medical therapy versus medical therapy alone in patients with HFrEF (EF ≤35%)
Results
In the combined cohort of 5697 participants, the median age was 60 (IQR 51-68) years, and 24% were women; baseline characteristics of the cohort by ethnicity are shown in Table II. In general, disease characteristics and comorbidities varied among the ethnic groups. Black or African American (median age 55) and Malay participants (median age 56) were the youngest, while white (median age 62) and Japanese/Korean (median age 67) participants were the oldest. Malay participants had the highest
Discussion
To our knowledge, these data represent the largest analysis of cross-continental ethnic differences in HRQoL among patients with chronic HF. Despite acknowledgement of the large and growing global public health burden of HF, substantial knowledge and care gaps exist, especially among low- and middle-income regions of Asia, where resources are particularly limited.23., 24. In this study, we show that—independent of clinical covariates—HRQoL as defined by the patient's KCCQ score is significantly

Prevalence and Prognostic Significance of Frailty in Asian Patients With Heart Failure: Insights From ASIAN-HF
2021, JACC: AsiaCitation Excerpt :The assessment of health-related quality of life in patients with HF was measured using the Kansas City Cardiomyopathy Questionnaire (KCCQ), a 23-item self-administered HF-specific questionnaire validated in multiple HF-related disease states (22-24). This instrument has been widely used in recent international HF clinical trials and has been validated in several languages (19). The KCCQ is the most sensitive surrogate measure to capture such patients' health status.

The KCCQ has also been used in assessing HRQL among Japanese, Korean, and Hindi languages (25). The KCCQ was administered at randomization to 4,735 (98%) patients.
