Abstract

Objectives: The study aims to evaluate the severity of heart failure (HF) and its impact on the patient's quality of life (QoL).

Methodology: A multicenter, observational study was conducted across 100 medical facilities in Pakistan. Symptomatic HF patients (NYHA Class-II to IV) diagnosed ≥ 1 year ago, aged ≥ 18 years, and advised for echocardiography were invited. A total of 961 patients agreed to participate. HF severity was assessed based on ejection fraction (EF %) and NYHA class. The Kansas City Cardiomyopathy Questionnaire (KCCQ) was used to assess the effect of HF on the patient's QoL.

Results: The patients' overall health status exhibited poor scores, with a mean KCCQ score of 20.26±8.34. Concerning left ventricular ejection fraction (LVEF), 25.9% of patients displayed moderate dysfunction (LVEF 30% to 39%), while 29.1% had severe dysfunction (LVEF < 30%). The distribution across NYHA classes was Class II included 451 patients (46.9%), Class III included 317 patients (33.0%), and Class IV included 193 patients (20.1%). High-quality-of-life (HR-QoL) assessments using the KCCQ exhibited significant correlations with both LVEF (rs=-0.394, p<0.01) and NYHA class (rs=-0.615, p<0.01). Notably, the mean KCCQ score displayed considerable variation across NYHA classes, Class II had a mean score of 25.42±7.95, Class III had 20.90±7.67, and Class IV had 16.41±8.94. Significant predictors of quality of life (KCCQ score) included age and NYHA.

Conclusion: It is concluded from the study results that HR-QoL is significantly correlated with the severity of HF based on ejection fraction and NYHA class.
