Association of Major and Minor ECG Abnormalities With Coronary Heart Disease Events.

The article provides information on a study which determined whether baseline electrocardiographic (ECG) abnormalities or development of new and persistent ECG abnormalities are associated with increased coronary heart disease (CHD) events. The population-based study enrolled 2,192 white and African American older adults aged 70 to 79 years from health, Aging and Body Composition Study without known cardiovascular disease (CVD). The study then assessed incident CHD events among participants without preexisting CVD at baseline.
