Diagnostic value of Peguero Lo Presti Electrocardiografic Index for diagnosis of Left Ventricle Hypertrophy in correlation with cardiovascular magnetic resonance

Abstract Funding Acknowledgements Type of funding sources: None. Background The gold standard for the diagnosis of left ventricular hypertrophy is cardiac magnetic resonance (CMR). Nonetheless, electrocardiogram is the most widely used screening test due to convenience, availability and low cost. There are more than 35 electrocardiographic indices to diagnose left ventricular hypertrophy among them stand out: Cornell, Sokolow-Lyon and the Index of Peguero- Lo Presti. Methods Retrospective cohort study that included 190 cardiovascular patients from January 2015 to December 2019 in a National Cardiology Center. We described demographic and electrocardiographic indices and correlate them with CMR information. A bivariate analysis was performed with association tests as Pearson, Chi square and Fisher’s exact 2x2 test. Results Our population included predominantly males (64.6%), with median age of 52 years, ischemic heart disease (74%), diabetes mellitus 2 (74%), dyslipidemia (67.9%), valvular heart disease (62.6%) and hypertension (51.6%.). Ventricular mass average140 grams, with a mean LVEF 52%. Electrocardiographic indices: Peguero Lo-Presti (75.3%) positive for left ventricular hypertrophy, Cornell Index ( 51.6%), Sokolow index (41.1%), RaVL (27.9%) and RDI (21.1%). Quantitative analysis: Peguero Lo-Presti index average 35.1 mm, Sokolow index: 30.9 mm, Cornel index: 25 mm. The most sensitive criteria to determine left ventricular hypertrophy was Peguero Lo-Presti 59.3% (95 CI 41.4% - 55.5%), followed by Cornell 51.6% (95% CI 44.5% - 58.6%), Sokolow Lyon 41.1% (95% CI34.3% to 48.2%). Conclusion Peguero- Lo Presti criteria are more sensitive than other electrocardiographic criteria for the diagnosis of left ventricular hypertrophy Electrocardiographic indices.
