Clinical-statistical analysis of chronic cardiac failure

Aim. To analyse epidemiologically chronic heart failure (CHF) according to 1996 records for patients admitted to therapeutic and cardiological departments of Moscow city hospital N 64. Materials and methods. An individual sheet has been developed for computer. The statistical processing has been conducted according to Access 97 program. It has covered 4019 case histories for 1996. 1232 patients were hospitalized for chronic cardiac failure this making 30.6% of all the hospitalizations. Results. CHF was encounted in 60.9% of females and 39.1% of males. It was due to: ischemic heart disease (63.7%, with myocardial infarction in 73%), hypertension (17.5%), valvular disease (13.7%), dilated cardiomyopathy (3.7%), myocarditides and perocarditis (1.4%). Age groups 30-39 years, 40-49, 50-59, 60-69, 70-79, 80-89, 90-99 consisted of 0.6, 4, 11, 35.2, 31.4, 16.9, 0.6% of patients respectively. Females prevailed in the oldest age groups. The time from CHF diagnosis was 2, 3, 4, 5, 6, 7, 8, 9 and > 10 years in 26, 10.9, 4, 5.7, 0.9, 1.4, 1.7, 0.6 and 4% of patients, respectively. 72.9% of patients were admitted to hospital once a year. 19.7%, 5.2%, 0.9%, 0.6%, 0.9% of patients were hospitalized 2, 3, 4, 5 and more than 6 times, respectively. CHF was responsible for 50(27.8%) lethal outcomes of 180. Lethality resulted from cardiovascular insufficiency (50%), thromboembolism (30%), pneumonia (10%). Conclusion. CHF is a frequent cause of hospitalizations. Development of CHF lethality, age groups distribution are closely associated with the patients' gender.
