Key result
Relative wall thickness >0.42 was independently associated with higher rates of LVH diagnosed by Cornell (OR 1.78; 95% CI 1.45-2.20), Sokolow-Lyon, and Peguero-Lo Presti voltage criteria.
Why the study?
To characterize the influence of relative wall thickness on Cornell, Sokolow-Lyon, and Peguero-Lo Presti voltages and elucidate its impact on diagnostic accuracy for LVH.
Does relative wall thickness influence electrocardiographic voltage measures and their diagnostic accuracy for left ventricular hypertrophy?

Does relative wall thickness influence electrocardiographic voltage measures and their diagnostic accuracy for left ventricular hypertrophy?
Effect estimate: OR 1.78 (95% CI 1.45-2.20)
RWT >0.42 may confound ECG LVH detection; hypothesis-generating for geometry-adjusted criteria in prospective studies.
Objective: To characterize the influence of relative wall thickness (RWT) on Cornell, Sokolow-Lyon and Peguero-Lo Presti voltages and elucidate its potential impacts on their diagnostic accuracy for LVH in a large general Chinese population.Methods: A total of 10,614 permanent residents aged ≥ 35 years were recruited for this study. All the participants were subjected to ECG and echocardiogram during the same visit. Multivariate linear and logistic regression analyzes were conducted to assess the influence of RWT on the voltages and their diagnostic performance for LVH detection.Results: A distinct correlation was identified between RWT and Cornell and Peguero-Lo Presti voltages following adjustments for age, gender and left ventricular mass (LVM) (β = 0.675 and 1.342, respectively; Ps < 0.001). Besides, subjects with RWT > 0.42 exhibited higher rates of LVH diagnosed by Cornell (OR = 1.78, 95% CI: 1.45–2.20), Sokolow-Lyon (OR = 1.30, 95% CI: 1.08–1.56), and Peguero-Lo Presti voltage (OR = 1.48, 95% CI: 1.29–1.70) after adjustments for age, gender and echocardiographic LVH. Furthermore, concentric remodeling or concentric hypertrophy displayed higher rates of LVH diagnoses via Cornell and Peguero-Lo Presti voltage criteria, as compared with normal geometry or eccentric hypertrophy, respectively (all Ps < 0.05), findings of which were independent of age, gender and LVMI.Conclusion: Echocardiographic RWT was independently correlated with electrocardiographic voltage measures of LVH, which influenced their positive rates and contributed to poor diagnostic performance.

Ye et al. (2020) conducted a cross-sectional in Left ventricular hypertrophy (n=10,614). Relative wall thickness (RWT) was evaluated on LVH diagnosed by Cornell voltage criteria (OR 1.78, 95% CI 1.45-2.20). Relative wall thickness >0.42 was independently associated with higher rates of LVH diagnosed by Cornell (OR 1.78; 95% CI 1.45-2.20), Sokolow-Lyon, and Peguero-Lo Presti voltage criteria.
