Background: Diabetes mellitus is highly prevalent amongst patients with heart failure, especially those with heart
failure and preserved ejection fraction (HFpEF), and patients with the two conditions have a higher risk of mortality
compared with patients without diabetes or heart failure. The aim of the study is to determine the prevalence of heart
failure among type 2 diabetic patients in Benha city, Egypt and to assess the different causes and risk factors of heart
failure (HF) and the impact of glycemic control on the prevalence of HF as well as the effect of different anti-diabetic
drugs on control of HF.
Patients and methods: This cross-sectional study was conducted on 200 patients with type 2 diabetes attending the
outpatient and inpatient clinics of Benha teaching hospital. All included patients were subjected to full history taking,
complete clinical examination and laboratory investigations.
Results: The prevalence of HF in diabetic patients was 35.5% [28 (39.4%) females and 43 (60.6%) males], while
patients without heart failure represented 64.5% [85 (65.9%) females and 44 (34.1%) males]. The mean age was 60
(SD 11) for patients with HF, and 58 (SD 11) years for those without HF. Glycemic control was significantly lower in
those with HF (9.9%) than those without HF (68.2%), with p
