Ambient Coarse Particulate Matter and the Right Ventricle: The Multi-Ethnic Study of Atherosclerosis.

ABSTRACT:

Background

Coarse particulate matter (P_10-2.5) is primarily mechanically generated and includes crustal material, brake and tire wear, and biological particles. PM_10-2.5 is associated with pulmonary disease, which can lead to right ventricular (RV) dysfunction. Although RV characteristics have been associated with combustion-related pollutants, relationships with PM_10-2.5 remain unknown.

Objectives

To quantify cross-sectional associations between RV dysfunction and PM_10-2.5 mass and components among older adults and susceptible populations.

Methods

We used baseline cardiac magnetic resonance images from 1,490 participants (45-84 y old) from the Multi-Ethnic Study of Atherosclerosis and assigned 5-y residential concentrations
