The relationship between obesity and pulmonary hypertension is well known. The aim of this study is to evaluate the relationship between pulmonary artery stiffness, right ventricular functions and bioelectrical impedance parameters in obese, overweight, and healthy individuals. Methods In this study, 41 obese (17 female and 24 male, mean age 43.5 +/- 10.3), 39 overweight (20 female and 19 male, mean age 38.6 +/- 10.4), 34 healthy control group (19 female and 15 male, mean age 40.5 +/- 8.6) were included. Anthropometric measurements and bioelectrical impedance parameters of all participants were performed. Right ventricular functions and pulmonary artery stiffness were evaluated by using conventional echocardiography. Results Right ventricle myocardial performance index, pulmonary artery stiffness values were statistically different between groups. Positive correlation was observed between pulmonary artery stiffness and Body Mass Index, Waist and Hip circumferences. Significant negative correlation was observed between muscle to fat ratio and pulmonary artery stiffness. In the linear regression analysis, it was observed that the muscle to fat ratio was independent predictor of pulmonary artery stiffness (beta = -1.835; 95%CI(-2.434 - - .784); p < 0.001). Conclusions This study showed that right ventricular function was impaired and pulmonary artery stiffness increased in obese individuals. These findings could be considered as early markers of pulmonary hypertension in obese patients who do not yet have clinical evidence of cardiovascular disease.eninfo:eu-repo/semantics/closedAccessbioelectrical impedanceobesitypulmonary artery stiffnessArticle3934904953514193810.1111/echo.153202-s2.0-85124537074Q3WOS:000753288000001Q4
