Northwestern University investigators suggest that late mortality following cardiac surgery for congestive heart failure (CHF) appears to be predicted by readmission within 30 days. Independent risk fac­tors for readmission included age, gender, and cardio­pulmonary bypass time. When compared with all patients readmitted for surgery-related causes, those readmitted for CHF had worse survival rates.
