心血管危险因素对左心室的影响是众所周知的，但尚未使用先进的成像技术研究其对右心室的影响。本研究的目的是确定心血管危险因素与右心室（RV）结构和功能之间的关系及其与左心室的相互作用。分析了多种族动脉粥样硬化研究中4,204名无临床心血管疾病的参与者的心脏磁共振图像。采用多元线性回归模型研究个体RV参数与危险因素之间的横截面相关性。除射血分数外，所有RV参数均随年龄增长而降低（p
The effect of cardiovascular risk factors on the left ventricle is well known but their effect on right ventricle has not been studied using advanced imaging techniques. The purpose of the present study was to determine the relation between the cardiovascular risk factors and right ventricular (RV) structure and function and its interaction with the left ventricle. Cardiac magnetic resonance images from 4,204 participants free of clinical cardiovascular disease in the Multi-Ethnic Study of Atherosclerosis were analyzed. Multivariate linear regression models were used to study the cross-sectional association between individual RV parameters and risk factors. All RV parameters, except for ejection fraction, decreased with age (p
