Abstract

Background: Overweight is currently considered as the main risk factor for various chronic disorders, especially cardiovascular diseases. Unexpected hypertension is the first reaction of heart to overburden imposed by obesity or overweight. The purpose of the present study was to evaluate the correlation between body mass index (BMI) and echocardiographic findings in overweight patients compared with normal-weight population.

methods: This historical cohort study was conducted on 60 patients divided into two group of 30 based on their measured weights, group 1 with BMI of 20-25 kg/m2 as control and group 2 with 25<BMI≤30 kg/m2. All demographic and clinical data along with the echocardiographic findings were recorded for all samples.

Results: The mean age of control (41.06 ± 12.82 years) and oversights (46.84 ± 12.61 years) was not significantly different (P = 0.067). Systolic blood pressure (P = 0.003) and pulse rate (P = 0.028) were significantly higher in overweight group; ejection fraction (P = 0.036), end-systolic (P < 0.001) and end-diastolic (P < 0.001) left ventricular dimensions, and left ventricular mass index (P = 0.005) were significantly higher in control group.

Conclusion: Overweighting due to anatomical remodeling can cause diastolic heart failure in left ventricle. According to the relatively poor prognosis of treatment features in patients with probable risk factors of heart failure such as diabetes, hypertension and ischemic heart disease (IHD), it is recommended to consider overweight as an effective prognostic factor.
