Mete-analysis of prevalence of ECG criteria for left ventricular hypertrophy diagnosis

Abstract

Introduction. Left ventricular hypertrophy is an important predictor for cardiovascular mortality and morbidity. ECG is the most accessible method of LVH diagnosis, but has a low sensibility. It's detection still remains an important factor that contributes to cardiovascular risk stratification. Aim of the study. The aim of the study is to evaluate the prevelance of different ECG criteria for left ventricular hypertrophy diagnosis in common population. Materials and methods. A comprehensive systematic search of studies published in different datebases like MEDLINE, EMBASE and Scopus were selected.The main inclusion criteria was the research of Sokolow-Lyon, Cornell index, Romhilt-Estes and RaVL ECG criteria. Results. 4 studies were indentified to correspond inclusion criteria.The included studies comprised 2209 patients.The sensibility of selected criteria are: Sokolow-Lyon 10-27%, Cornell index 23-45%, Romhilt-Estes 24-49%, RaVL 8-26%. The revealed heterogeneity is due to differences of pupulation groups such as age, gender,race and presence of comorbidities Conclusions. The findings of this study revealed that Romhilt-Estes score is the most relevant ECG criteria for left ventricular hypertrophy diagnosis for common population.
