BackgroundThere is extensive evidence that low serum levels of high-density lipoprotein (HDL) cholesterol and apolipoprotein A-I (apoA-I) predict a worse prognosis in patients with ischemic heart disease. This study examined whether apoA-I levels may also provide prognostic information in patients with nonischemic heart failure.Methods and ResultsA prospective follow-up study was performed in 117 consecutive patients with nonischemic heart failure for a period of ≤36 months until the first occurrence of 1 of the following clinical events: all-cause death, cardiac death, and hospitalization with worsening heart failure. Serum levels of apoA-I were measured by immunoturbidimetry. A clinical event occurred during follow-up in 28 (24%) patients. A multivariate Cox proportional hazards analysis showed that lower apoA-I levels (<103 mg/dL: determined by a receiver-operating characteristic analysis) were significantly associated with an adverse outcome that was independent of creatinine clearance, HDL cholesterol levels, and brain natriuretic peptide levels. ApoA-I was inversely correlated with levels of C-reactive protein and fibrinogen, known inflammatory predictors of poor prognosis in heart failure.ConclusionsLow levels of apoA-I are independently associated with an adverse prognosis in patients with nonischemic heart failure. ApoA-I may play a beneficial role in nonischemic heart failure partly through an anti-inflammatory action.
