Sex Differences in Age of Onset of Premature Cardiovascular Disease and Subtypes: The Coronary Artery Risk Development in Young Adults Study

Background Historical data indicate men develop coronary heart disease (CHD) 10 years before women. However, whether this sex gap persists in a contemporary sample amid changing cardiometabolic risk profiles, and whether differences exist for other cardiovascular disease (CVD) subtypes (ie, stroke, heart failure), is not known.
