    Abstract

    Background It has been recently reported that the Romhilt-Estes (R-E) score, originally proposed for detection of left ventricular hypertrophy from the electrocardiogram, is a strong predictor of all-cause mortality. Whether the R-E score is also predictive of cardiovascular disease (CVD) and whether its individual components differ in their ability to predict different CVD outcomes are not well established. Methods This analysis includes 13,261 participants from the ARIC study who were free of CVD at baseline (1987-1989). Incident CVD, coronary heart disease (CHD), heart failure (HF), and stroke were ascertained by an adjudication committee through December 2010. The R-E left ventricular hypertrophy score was measured from automatically processed baseline electrocardiogram data. Cox proportional hazard models were used to examine the association between baseline the R-E overall score (overall) and each of its 6 individual components separately, with each of the CVD outcomes. Results During a median follow-up of 21.8 years, 3,579, 2,205, 1,814, and 731 CVD, CHD, HF, and stroke events, respectively, occurred. In multivariable adjusted models, R-E score 4 points (compared with 0 points) was associated with increased risk of CVD, CHD, HF, and stroke (hazard ratio [95% CI] 1.66 [1.41-1.96], 1.66 [1.34-2.07], 1.97 [1.60-2.43], and 1.49 [1.07-2.07], respectively). The 6 component of the R-E score varied in their relationship to different CVD outcomes. Conclusions The R-E score is predictive of CVD outcomes. The 6 R-E score components differ in their associations with different CVD outcomes, indicating that they may be electrical biomarkers of different physiological events within the myocardium.
