Velavan P, Khan NK, Goode K, Rigby AS, Loh PH, Komajda M, Follath F, Swedberg K, Madeira H, Cleland JG: Predictors of short term mortality in heart failure - insights from the Euro Heart Failure survey. vi.
OBJECTIVE: To identify factors associated with short term mortality in hospitalised patients with heart failure. BACKGROUND: Hospitalisation is frequent in patients with heart failure and is associated with a high mortality. METHODS: The Euro Heart Failure survey collected data from patients with suspected heart failure. We searched this data for predictors of short term mortality. RESULTS: Of 10,701 patients, 1404 (13%) died within 12 weeks of admission. On univariate analysis, increasing age, hyponatraemia, renal impairment, hyperkalaemia, anaemia, severe mitral regurgitation, severe LV systolic dysfunction (LVSD), increasing QRS and female sex carried adverse prognosis. ACEI, beta-blockers, nitrates, anti-thrombotic and lipid lowering drugs were associated with a better prognosis. On multivariable analysis the following provided independent prognostic information: increasing age (OR per SD=1.5, 95% CI 1.4-1.6), severe LVSD (1.8, 1.5-2.1), serum creatinine (1.2, 1.2-1.3), sodium (0.9, 0.8-0.9), Hb (0.9, 0.8-0.9) and treatment with ACEI (0.5, 0.5-0.6), beta-blockers (0.7, 0.6-0.8), statins (0.6, 0.5-0.7), calcium channel blockers (0.7, 0.6-0.8), warfarin (0.5, 0.4-0.6), heparin (1.7, 1.4-1.9), anti-platelet drugs (0.6, 0.5-0.6) and need for inotropes (5.5, 4.6-6.6). A simple risk score (range 0-11) identified cohorts with a 12 week mortality ranging from 2% to 44%. CONCLUSIONS: Simple and readily available clinical variables and a risk score based on medical history and routine tests that all patients admitted with heart failure have, can identify patients with good, intermediate and high short term mortality. |
