Evaluation of Anthropometric Indices of Patients with Left Ventricle Dysfunction Fallowing First Acute Anterior Myocardial Infarction

Introduction: In the current study, we evaluated the effect of anthropometric indices on ejection fraction following first acute anterior myocardial infarction. Methods: In an analytic-cross sectional study, 50 patients with acute anterior myocardial infarction and abnormal anthropometric indices (Body Mass Index (BMI) ≥ 30, Waist Hip Ratio (WHR) ≥ 1 and ≥ 0.85 in males and females respectively and Waist Circumference (WC) ≥ 102 cm and ≥ 88 cm in males and females respectively) were recruited as case group and 50 patients with acute anterior myocardial infarction and normal anthropometric indices as control group. Subsequently, the relation between anthropometric indices and left ventricle dysfunction was evaluated and compared between two groups. Results: 77 people of the studied patients were male and 23 female with the mean age of 59± 1.2 years and an age range of 32-90 years. To evaluate the left ventricle function, the mean ejection fraction of the patients was measured as 34.3± 7.2 % and 44.8± 6.3% in patients with abnormal anthropometric indices and patients with normal anthropometric indices respectively (P= 0.0001). Calculation of the correlation coefficient between ejection fraction and BMI, WHR and WC in males and females revealed a moderate reverse (r=-0.521 to r=-0.691) and statistically significant (P= 0.0001) relations which was of more strength in females. Conclusion: Anthropometric indices including BMI and waist circumference influence cardiac function following myocardial infarction.
