摘要

Background: This study aimed to investigate the relationship between malnutrition and outcomes in patients with decompensated severe systolic heart failure (HF) focusing on clinical presentations and medication use. Methods: This study prospectively enrolled 108 patients admitted for severe systolic HF with a left ventricular (LV) ejection fraction < 35%, low cardiac output, and high LV filling pressure. Five patients died during the index hospitalization, and the remaining 103 patients were followed up for 2 years. The primary endpoints were HF rehospitalization and all-cause mortality. Nutritional risk index (NRI) was calculated as (1.519×serum albumin, g/L) + (41.7×body weight/ideal body weight). Results: Forty-four patients reached the study endpoints. An NRI ≤93 predicted events. The NRI ≤ 93 group had higher pulmonary artery systolic pressure, more edema over dependent parts, longer hospital stay, and more primary endpoints compared to the NRI > 93 group. The NRI ≤ 93 group received fewer evidence-based medications and more loop diuretics compared to the NRI > 93 group. NRI was an independent predictor of cardiovascular events [hazard ratio 0.902; 95% confidence interval (CI) 0.814-0.982 per 1 point increase; p = 0.012]. Low NRI was associated with a significantly higher use of loop diuretics [odds ratio (OR) 2.75; 95% CI 1.046-5.647; p = 0.004] and significantly lower use of beta blockers (OR 0.541; 95% CI 0.319-0.988; p = 0.002). Conclusions: Malnutrition assessed using the NRI was associated with cardiovascular events in the patients with severe systolic HF with low cardiac output and high LV filling pressure. Low NRI was associated with more diuretic and less beta blocker use.
