Sugiura T, et al. - Researchers searched for the possible associations between electrocardiogram (ECG) findings relevant to the QRS wave and high-sensitivity cardiac troponin I (hs-cTnI) in the general population. As per univariate and multivariate regression analysis, Sokolow–Lyon voltage, QRS duration, and product of QRS duration and voltage (Cornell product) were markedly correlated with high-sensitivity cardiac troponin I (hs-cTnI) after adjustment for possible confounding factors, including B-type natriuretic peptide. Logistic regression analysis with the endpoint of higher hs-cTnI than the median value demonstrated an independent association of Sokolow–Lyon voltage and Cornell product with increased hs-cTnI concentrations. In the general population, ECG findings relevant to the QRS wave, especially increased QRS voltage, are noted to be associated with hs-cTnI.
