Nomsawadi V, et al. - Through a study on 1,882 patients who were referred for cardiac magnetic resonance (CMR), the researchers assessed the diagnostic performance of electrocardiographic (ECG) criteria in comparison to diagnosis by CMR imaging for the diagnosis of left ventricular hypertrophy (LVH) among various body mass index (BMI) groups. Thirty-four underweight, 144 normal weight, 100 overweight, and 181 obese patients were diagnosed with LVH. The overall specificity and sensitivity of ECG were high and low, respectively. Similar specificity of each ECG criterion among BMI groups was noted. However, a decreasing trend in the higher BMI groups was exhibited by the sensitivity of ECG criteria. Hence, relatively high specificity and relatively low sensitivity were demonstrated through all ECG criteria. Higher BMI was discovered to be related to the decreased sensitivity, although, the specificity across groups continued to be the same.
