[Survival and risk factors in patients with chronic cardiac insufficiency (results of a long-term prospective observation)].

Based on a 10-year prospective follow-up a study was made into survival in 68 patients with chronic cardiac insufficiency (CCI) having developed as a result of hypertensive disease and postinfarction cardiosclerosis. Also studied in the above series were risk factors for death. It has been found out that life span in CCI is, in the mean, seven years while risk for death beyond 10 years increases six-fold. The identified prognostic factors included etiology of CCI, age of patients, end-systolic volume of the left ventricle, and a week dosage of furosemide. It was etiology of CCI that proved to be the most significant risk factor. In some patients with postinfarction cardiosclerosis and CCI average life span comes up to more than five years, with risk for death being significantly higher than in CCI patients with CCI having developed in the wake of hypertensive disease over the whole of the period of study.
