Objectives: The aim of this review was to examine the prevalence, incidence and risk factors of chronic heart failure in the type 2 diabetic population.
Methods: A systematic search of studies related to chronic heart failure (CHF) in the diabetic population was performed using medical databases.
Results: 1) The prevalence of CHF in the diabetic population was approximately 10-23% in the large previously studied cohort. This was about three times higher than in non-diabetic control groups. 2) The incidence of CHF in diabetes varied greatly. It was influenced by the time of follow-up, the mean age of patients, the state of metabolic control and the complications of diabetes. The incidence of CHF in patients with diabetes was approximately two-fold greater than in the non-diabetic population. 3) The main risk factors of CHF in the type 2 diabetic population were age, hemoglobin A1c (HbA1c), coronary heart disease, hypertension, microalbuminuria and obesity.
Conclusions: The prevalence and incidence of CHF were found to be high in the diabetic population, and the risk factors of CHF were somewhat different from those in the general population.
