Abstract

Background: Left ventricular diastolic dysfunction (LVDD) provides incremental prognostic valuein the elderly population. It is unclear whether protein malnutrition is related to diastolic heart dysfunction in the hospitalized elderly male patients. Methods: A total of 199 male patients aged older than 50were recruited. Protein malnutrition was defined as serum albumin less than 35g/L. Laboratory tests for biochemical indicators, transthoracic echocardiography and anthropometric measures were performed at admission. Results: Patients with protein malnutrition was older than those with normal protein nutrition (P=0.003).The prevalence of LVDD was 67.4% in patients without protein malnutrition and 73.2% in those with protein malnutrition. In subgroup analysis for the patients aged more than 80 years old, the prevalence of LVDD in patients with and without protein malnutrition was still not significantly different. However, serum N-terminal pro-brain natriuretic peptide (NT-proBNP) level was closely related to protein malnutrition in in-hospital middle-elderly male patients, and serum NT-proBNP level had a moderate value for diagnosing malnutrition. Conclusions: Protein malnutrition wasn’t related to LVDD, however it was related to serum NT-proBNP level in the hospitalized middle-elderly male patients with preserved left ventricular ejection fraction.
