Improvement in Health-related Quality of Life After Hospitalization Predicts Event-free Survival in Patients With Advanced Heart Failure

Background: Health-related quality of life (HRQOL) is a major clinical Outcome for heart failure (HF) patients. We aimed to determine the frequency, durability, and prognostic significance of improved HRQOL after hospitalization for decompensated HF. Methods and Results: We analyzed HRQOL, measured serially using the Minnesota Living with Heart Failure Questionnaire (MLHFQ), for 425 patients who survived to discharge in a multicenter randomized clinical trial Of pulmonary artery catheter versus clinical assessment to guide therapy for patients with advanced HE All patients enrolled had 1 or more prior HF hospitalizations or chronic high diuretic doses and 1 or more symptom and 1 sign of fluid overload at admission. Improvement, defined as a decrease of more than 5 points in MLHFQ total score, Occurred in 68% of patients by 1 month and stabilized. The degree of 1-month improvement differed (P < .0001 group x time interaction) between 6-month Survivors and non-survivors. In a Cox regression model, after adjustment for traditional risk factors for HF morbidity and mortality, improvement in HRQOL by 1 month compared to worsening at 1 month or no change predicted time to subsequent event-free survival (P = .013). Conclusions: In patients hospitalized with severe HF decompensation, HRQOL is seriously impaired but improves substantially within 1 month for most patients and remains improved for 6 months. Patients for whom HRQOL does not improve by 1 month after hospital admission merit specific attention both to improve HRQOL and to address high risk for poor event-free Survival.
