Clinical characteristics and prognosis of hospitalized patients with congestive heart failure--a study in Fukuoka, Japan.
The clinical characteristics and prognosis of patients with congestive heart failure (CHF) have been described by a number of previous studies, but very little information is available on this issue in Japan. This study aimed to delineate the clinical characteristics and prognosis of Japanese patients hospitalized with CHF. Medical records were reviewed for 230 consecutive patients at 5 teaching hospitals in Fukuoka, Japan from January to December 1997 and the survival and hospital readmission were followed through December 1999 (mean follow-up, 2.4 years). The study population had a high mean age, contained a larger population of women especially in the older ages, and had a higher incidence of overt HF (48%) despite a relatively normal ejection fraction on echocardiography. Major causes of CHF were ischemic, valvular, and hypertensive heart diseases. The 1-year mortality rate was as low as 8.3% whereas rates of hospital readmission because of an exacerbation of CHF were as high as 40% during the follow-up period. Patients hospitalized with CHF in routine clinical practice in Japan have characteristics that differ from those in the population included in community-based studies or large clinical trials.
