Regional left ventricular systolic function and the right ventricle: the multi-ethnic study of atherosclerosis right ventricle study.

ABSTRACT:

Background

Dysfunction of the interventricular septum has been implicated in right ventricular (RV) failure. However, little is known about the relationship between ventricular septal and RV function in patients without clinical cardiovascular disease. We hypothesized that better septal function would be associated with higher RV ejection fraction and lower RV mass and volume by cardiac MRI.

Methods

In the Multi-Ethnic Study of Atherosclerosis (MESA), cardiac MRI was performed on community-based participants without clinical cardiovascular disease. Images were analyzed by the harmonic phase method to measure peak circumferential systolic midventricular strain for each wall (anterior, lateral, inferior, and septal). Multivariable linear regression and generalized additive mod
