Nomsawadi V, et al. - In 1,882 patients who were referred for cardiac magnetic resonance (CMR), researchers assessed the diagnostic performance of electrocardiographic (ECG) criteria for detecting left ventricular hypertrophy (LVH) across various body mass index (BMI) groups and compared it to diagnosis by CMR imaging. The BMI categories were underweight (n=67, <18.5 kg/m2), normal (n=459, 18.5–22.9 kg/m²), overweight (n=434, 23–24.9 kg/m²), and obese (n=922, ≥25 kg/m²). Using CMR, they assessed left ventricular function, volume, and mass. They also measured standard ECG criteria including Cornell voltage, Cornell product, Romhilt-Estes point score system, Sokolow-Lyon index, and Sokolow-Lyon-Rappaport index. Relatively high specificity and relatively low sensitivity were displayed by all ECG criteria. Similar specificity was seen across BMI groups; there was a link between higher BMI and decreased sensitivity.
