OBJECTIVE: The DIABHYCAR (type 2 DIABetes, Hypertension, CArdiovascular Events and Ramipril) study allowed investigators to analyze factors leading to the development of congestive heart failure (CHF) in type 2 diabetic patients with abnormal urinary albumin concentration.
RESEARCH DESIGN AND METHODS: Type 2 diabetic subjects of both sexes aged >or=50 years who had a urinary albumin concentration >or=20 mg/l were randomly allocated to 1.25 mg/day ramipril or placebo in addition to their usual treatment and treated for 3-6 years in a double-blind fashion. Major outcomes including hospitalization for CHF were recorded during the follow-up.
RESULTS: Of the 4912 included patients, 187 developed CHF during the study. There was no significant difference in the incidence of CHF between the two treatment groups. Using a multivariate analysis, independent risk factors for the occurrence of CHF were age, history of cardiovascular disease, baseline urinary albumin concentration, baseline HbA(1c), and smoking habits. A total of 68 of the 187 patients (36.4%) died during the 12 +/- 11-month period after the first hospitalization for CHF, whereas the annual mortality rate of the population who did not develop CHF was 3.2%.
CONCLUSIONS: Presence of atherosclerotic disease, baseline urinary albumin concentration, and HbA(1c) level were indicators for further development of CHF. Occurrence of CHF is a major prognostic turn in a diabetic patient's life.
