PurposePatients with advanced heart failure have disordered thermoregulation. Whether lower body temperatures are associated with worse survival is uncertain.MethodsWe used data on 56,659 patients 65 years or older from the National Heart Care (NHC) Project. In addition to clinical data, admission body temperature was recorded. Patients were grouped a priori into 3 categories based on body temperature: 1)38°C. Survey logistic regression and fractional polynomial logistic regression were used to determine the independent association of body temperature with in-hospital and one-year mortality.ResultsMean body temperature in the study population was 36.5°C (± 0.005°C); 10,754 (18.5%) patients had body temperatures below 36°C while 1145 (1.9%) patients had body temperatures over 38°C. After multivariate adjustment, patients with body temperatures below 36°C had higher in-hospital (adjusted risk ratio [RR], 1.28; p
