EVALUATION OF PEGUERO-LO PRESTI CRITERIA FOR ASSESSMENT OF LEFT VENTRICULAR HYPERTROPHY

Background and objectives: The sensitivity of ECG to diagnose LVH by Peguero-Lo Presti criteria has shown higher sensitivity when compared to well established criterion like Cornell voltage and Sokolow Lyon criteria. This study was aimed to find the accuracy of Peguero Lo Presti criteria in the diagnosis of LVH in patients with hypertension. Methodology: This one cross-sectional study was conducted in the Department of Cardiology of a tertiary care centre in North Karnataka from May 2017 to October 2017. A total of 400 patients with age > 30 years having hypertension were studied. All the patients were subjected to ECG and 2D echo. Results: In this study majority (73.5%) of the patients were males and male to female ratio was 2.77:1. Most of the patients were aged between 61 to 70 years (38.50%) and the mean age was 63.79?10.36 years. Based on 2D echocardiography, LVH was diagnosed in 48% of the patients. Based on, Peguro-lo-presti, Cornell Voltage and Sokolow-Lyon criteria 30.50%, 24.50% and 21% of the patients were diagnosed to have LVH respectively. Of the 192 patients, one hundred and four (104) patients were diagnosed to have LVH based on Peguro-lo-presti criteria with strong agreement (p<0.001) between Peguro-lo-presti criteria and 2D echocardiograpgy for the diagnosis of LVH with sensitivity of 54.17%. Also using Cornell Voltage criteria 76 out of 192 were diagnosed to have LVH and the sensitivity was 39.58% and using Sokolow-Lyon criteria, 56 out of 192 were diagnosed to have LVH with sensitivity of 29.17%. The Peguero-Lo Presti ECG criteria yielded higher sensitivity (54.17%) and specificity (91.35%) in the diagnosis of LVH in patients with hypertension. Conclusion: Peguero-Lo Presti criteria has higher sensitivity and specificity in the ECG diagnosis of LVH compared to Sokolow-Lyon and Cornell voltage criteria considering LV mass index by 2D Echocardiography as reference standard.
