Sex differences with respect to clinical characteristics, treatment, and long-term outcomes in patients with heart failure.

The effect of sex on the etiology, risk factors, comorbidities, treatment and prognosis in patients with heart failure (HF) encountered in routine clinical practice in Asian populations has not been well described. The objective of the present study was to elucidate sex differences with respect to the clinical characteristics, treatment, and prognosis of HF patients treated in routine clinical practice settings using the Japanese Cardiac Registry of Heart Failure in Cardiology (JCARE-CARD) database, which is a nationwide registry for hospitalized patients with HF in Japan. JCARE-CARD enrolled 2675 patients hospitalized for HF at 164 participating hospitals from January 2005 to June 2006. HF was diagnosed by the simultaneous presence of at least two major criteria or onemajor criterion in conjunctionwith twominor criteria by use of the criteria from the Framingham Heart Study [1]. For each patient, baseline data recorded on the form were: demography; HF causes; comorbidities; complications; clinical status; echocardiographic findings; plasma B-type natriuretic peptide (BNP); and treatments. Longterm follow-up data could be obtained from 2305 patients after hospital discharged. Mean post-discharge follow-up was 2.3±0.7 years.
