Abstract
Although higher body mass index (BMI) is associated with adverse left ventricular morphology and functional remodeling, its possible association with right ventricular (RV) dysfunction has not been extensively evaluated. RV free wall longitudinal strain (RVLS) is emerging as an important tool to detect early RV dysfunction. This study aimed to investigate the independent effect of increased BMI on RVLS in a large sample of the general population without overt cardiac disease. We examined 1,085 participants (603 men, mean age 62 years) who voluntarily underwent an extensive cardiovascular health check-up. This included laboratory tests and speckle-tracking echocardiography to assess RVLS. The association between BMI and RVLS was determined by logistic regression analyses. The prevalence of abnormal RVLS (>-19.2%) was greatest in obese individuals (29.7%), followed by overweight (16.3%), and normal weight (10.6%, p <0.001). In multivariable analyses, BMI was significantly associated with abnormal RVLS (adjusted odds ratio [OR] = 1.07 per 1 kg/m2, p = 0.033) independent of traditional cardiovascular risk factors, pertinent laboratory and echocardiographic parameters including RV size and pulmonary artery systolic pressure. In subgroup analyses, BMI was significantly associated with abnormal RVLS in men (adjusted OR 1.10 per 1 kg/m2, p = 0.032) and younger (<65 years) participants (adjusted OR 1.13 per 1 kg/m2, p = 0.011), but not in women and the elderly. In a sample of the general population, higher BMI was independently associated with subclinical RV dysfunction. Furthermore, an increased BMI may carry different risk for impaired RVLS depending on the age and sex.
