Abstract

Background: Acute heart failure (HF) carries high hospital mortality rates in older patients; a multimarker strategy may help identify patients at high risk. Aims: To investigate prospectively the prognostic relevance of serum albumin and serum total cholesterol (TC) in older patients with severe, acute HF. Methods: Usual prognostic variables were collected on admission in 207 consecutive patients aged > 70 years with severe, acute HF. Serum albumin and serum TC were obtained soon after clinical improvement. Results: Hospital mortality rate was 19%. Patients who died were similar to patients who survived in terms of age, sex, heart rate, serum haemoglobin and left ventricular ejection fraction. Patients who died had higher concentrations of B-type natriuretic peptide (BNP), blood urea nitrogen, serum creatinine, C-reactive protein and serum troponin I, lower systolic blood pressure, and lower concentrations of serum albumin and serum TC than patients who survived (P < 0.01 for all). Serum albumin was the best independent predictor of hospital death (odds ratio 0.82 [0.74-0.90], P < 0.001), with blood urea nitrogen (P = 0.02) and log (BNP) (P = 0.02). A simple risk score based on serum albumin (< 3 g/dL; 2 points), BNP (> 840 pg/mL; 1 point) and blood urea nitrogen (> 15.3 mmol/L; 1 point) discriminated patients without (score 0 to 1, hospital death 4%) from patients with (score 2 to 4, hospital death 35%, P < 0.001) a high risk of death. Conclusion: Hypoalbuminaemia offers powerful additional prognostic information to usual prognostic variables in older patients with severe, acute HF, and deserves further attention in multimarker strategies. © 2011 Elsevier Masson SAS.
