ABSTRACT
Background:
The association of obesity with right ventricular function and the interplay between right heart and pulmonary circulation is incompletely understood. We evaluate the role of obesity as a determinant of right ventricular-pulmonary artery coupling (RVAC).Methods:
We retrospectively studied consecutive subjects without overt cardiovascular or pulmonary disease. Subjects were stratified according to body mass index (BMI) as normal weight, overweight, or obese. A transthoracic echocardiographic study was used to assess left and right heart functional and structural parameters. RVAC was assessed using the ratio of peak systolic velocity of the tricuspid annulus to pulmonary artery systolic pressure (PASP).Results:
A total of 145 subjects were enrolled with diabetes mellitus incidence higher in obese. There was no difference in left ventricular global longitudinal strain and in PASP or markers of right ventricular systolic function based on BMI. RVAC was significantly lower in the presence of obesity (normal weight 0.52 (0.19) cm·(sec·mmHg)-1 vs. overweight 0.47 (0.16) cm·(sec·mmHg)-1 vs. obese 0.43 (0.14) cm·(sec·mmHg)-1, p = 0.03), even after adjustment for confounders (ß -0.085, 95% confidence interval -0.163, -0.009, p = 0.029).Conclusions:
Our findings highlight the relationship between metabolic impairment and RVAC, suggesting additional mechanisms for heart failure development observed in obese subjects.
