Percent emphysema and right ventricular structure and function: The MESA Lung and MESA-RV Studies.

CONCLUSIONS: Percent emphysema was associated with smaller RV volumes and lower mass. The relationship of emphysema to cardiac function is complex but likely involves increased pulmonary vascular resistance predominantly with reduced cardiac output, pulmonary hyperinflation, and accelerated cardiopulmonary aging.
