Coronary artery diseaseElectrocardiographic Findings and Incident Coronary Heart Disease Among Participants in the Atherosclerosis Risk in Communities (ARIC) Study
Section snippets
Study population
From 1987 to 1989, the Atherosclerosis Risk in Communities (ARIC) study8 recruited 15,792 men and women aged 45 to 64 years by probability sampling in 4 communities: Forsyth County, North Carolina, Jackson, Mississippi, the northwestern suburbs of Minneapolis, Minnesota, and Washington County, Maryland. In Jackson, a representative sample of only black persons was selected. Communities in Maryland and Minnesota had <1% of blacks, and in North Carolina, the cohort comprised 12% blacks.
Baseline measurements
Results
The sample free of CHD and not taking specific cardiac medications at baseline comprised 2,190 black women, 5,177 white women, 1,358 black men, and 4,262 white men. Black and white men and women differed in baseline risk characteristics in the expected fashion (Web Table 1; see the Journal web site [www.AJConline.org]) and as previously reported in other ARIC publications.17
Age-adjusted, race- and gender-specific baseline prevalences of ECG variables are reported in Table 1. The most prevalent
Discussion
In the middle-age population-based ARIC study, among those free of CHD and not using specific cardiac medications, the prevalence of individual ECG abnormalities was low and comparable to the findings in other populations.2 The gender differences in the prevalence of some ECG findings in ARIC are similar to those reported by others.2
Few population-based studies have examined ECG findings in blacks. In the Evans County Study,3 high-amplitude R-wave and major T-wave abnormalities were more common
