| Summary: | <h4>Background</h4>The Peguero-Lo Presti criteria are novel electrocardiographic (ECG) diagnostic criteria for the detection of left ventricular hypertrophy (LVH) and represent the sum of the amplitude of the deepest S wave in any lead with the S wave in lead V4 (SD+SV4). The diagnostic efficacy of the Peguero-Lo Presti criteria in LVH is still debatable. We aimed to test the sensitivity and specificity of the Peguero-Lo Presti criteria and compared them with those of the Cornell voltage index to assess their overall performance in LVH diagnosis.<h4>Methods</h4>Electronic databases (e.g., Medline, Web of Knowledge, Embase, and the Cochrane Library) were searched from their inception until May 18, 2020. Trials written in English that investigated the Peguero-Lo Presti criteria for detecting LVH were included. Data were independently extracted and analyzed by two investigators.<h4>Results</h4>A total of 51 records were screened, and 6 trials comprising 13,564 patients were finally included. A bivariate analysis showed that the sensitivity of the Peguero-Lo Presti criteria (0.52, 95% confidence interval (CI) 0.46-0.58) was higher than that of the Cornell voltage index (0.29, 95% CI 0.23-0.36) and Sokolow-Lyon criteria (0.24, 95% CI 0.21-0.27); the diagnostic accuracy of the Peguero-Lo Presti criteria (0.69, 95% CI 0.65-0.73) was also higher than that of the Cornell voltage index (0.67, 95% CI 0.62-0.71) and Sokolow-Lyon criteria (0.28, 95% CI 0.25-0.32); and the specificity of the Peguero-Lo Presti criteria (0.85, 95% CI 0.79-0.90) was similar to that of the Cornell voltage index (0.92, 95% CI 0.89-0.95) and Sokolow-Lyon criteria (0.94, 95%CI 0.88-0.97). Two trials (including 12,748 patients) were discharged because they included partly healthy subjects and accounted for substantial heterogeneity. Pooled analysis of the remaining 4 trials (including 816 patients) showed that the sensitivity of the Peguero-Lo Presti criteria (0.56, 95% CI 0.51-0.61) was also higher than that of the Cornell voltage index (0.36, 95% CI 0.31-0.42) and Sokolow-Lyon criteria (0.24, 95% CI 0.18-0.31); the diagnostic accuracy of the Peguero-Lo Presti criteria (0.84, 95% CI 0.80-0.87) was also higher than that of the Cornell voltage index (0.54, 95% CI 0.50-0.58) and Sokolow-Lyon criteria (0.38, 95% CI 0.34-0.42); and the specificity of the Peguero-Lo Presti criteria (0.90, 95% CI 0.87-0.92) was similar to that of the Cornell voltage index (0.93, 95% CI 0.88-0.96) and Sokolow-Lyon criteria (0.97, 95% CI 0.90-0.99). Both the likelihood ratio and posttest probability of the Peguero-Lo Presti criteria and Cornell voltage index were moderate.<h4>Conclusion</h4>Based on this systematic review and meta-analysis, the Peguero-Lo Presti criteria-based ECG diagnostic method for LVH has high sensitivity, specificity and diagnostic accuracy and should be applied in clinical practice settings.
