BACKGROUND: In chronic heart failure (HF), lower total cholesterol (TC) levels have been associated with increased mortality. However, the relationship between lipid levels and outcomes in acute HF has not been studied. This study investigates the relationship between cholesterol levels and in-hospital mortality in patients hospitalized with acute HF. METHODS: The Get With the Guidelines-Heart Failure registry prospectively collects data on patients hospitalized with HF. We analyzed data on 17,791 patients admitted between January 2005 and June 2007 at 236 participating hospitals who had TC levels recorded. Baseline patient characteristics, treatment regimens, and in-hospital mortality were examined by TC level (mg/dL) quartiles (Q) as follows: Q1 (TC < or =118), Q2 (TC 119-145), Q3 (TC 146-179), and Q4 (TC > or =180). RESULTS: Mean TC level was 150 +/- 47 mg/dL. Patients with lower TC were older and had higher prevalence of ischemic heart disease. Of the patients, 46% were on a lipid-lowering drug, including 58%, 50%, 43%, and 34% of patients in TC Q1 to Q4, respectively. In-hospital mortality in TC Q1 to Q4 was 3.3%, 2.5%, 2.0%, and 1.3%, respectively (P < .0001). On multivariable adjusted analyses, each 10-mg/dL increase in TC level was associated with 4% decreased risk of in-hospital mortality (odds ratio 0.96, 95% CI 0.93-0.98). CONCLUSIONS: In patients hospitalized with HF, lower TC levels independently predict increased in-hospital mortality risk. Further evaluation of optimal cholesterol levels and influence of lipid-lowering medication use on outcomes in this population is warranted.
