Predictors of diffuse coronary artery calcium phenotype in adults aged ≥ 75: The Atherosclerosis Risk in Communities (ARIC) study.

ABSTRACT:

Introduction

Coronary artery calcium (CAC) scoring is a commonly used tool for cardiovascular disease (CVD) risk assessment and is reported using the Agatston score. However, there has been increasing interest in measures of CAC beyond the Agatston score, including measures capturing the overall distribution of vessel calcification. We assessed the association between 30-year traditional risk factor exposure and the presence of a more diffuse pattern of CAC in older adults aged 75 and older.

Methods

We studied participants in the Atherosclerosis Risk in Communities (ARIC) study who underwent CAC scoring and were free of prior CVD. Time-weighted average exposure to traditional cardiovascular risk factors (over 30 years) was calculated. The CAC diffusivity index was calculated
