摘要

Background: Malnutrition is associated with a poor prognosis in cardiovascular diseases, however the prognostic impact of the Controlling Nutritional Status (CONUT) score in patients with pericardial effusion (PE) is not known. Methods: This was a retrospective study conducted among 301 consecutive patients with PE who underwent pericardiocentesis. CONUT score was calculated from serum albumin level, total cholesterol level and lymphocyte count. The prognostic role of admission CONUT score on long-term mortality was evaluated. Results: The patients were divided into two groups according to long-term mortality. A total of 131 patients died during follow-up. In multivariable regression analysis, chronic heart failure [hazard ratio (HR): 3.21, 95% confidence interval (CI): 1.18-8.70, p ＜ 0.01], malignancy (HR: 5.67, 95% CI: 3.34-9.63, p ＜ 0.01) and CONUT score (HR: 1.21, 95% CI: 1.10-1.33, p ＜ 0.01) were found to be independent predictors of long-term mortality. CONUT score was significantly higher in the patients who died (5.8 ± 2.4 vs. 3.6 ± 2.2, p ＜ 0.01). In receiver operating characteristics analysis, a CONUT score ≥ 4.5 predicted long-term mortality with 66% sensitivity and 69% specificity (area under curve: 0.73, 95% CI: 0.67-0.79, p ＜ 0.01). Conclusions: In patients with PE, CONUT score is an independent prognostic factor for mortality.
