Valor pronóstico de la hipertrofia ventricular izquierda valorada por voltaje en electrocardiograma en pacientes con síndrome coronario crónico

Abstract

Introduction and objectivesMost patients with chronic coronary syndrome altered electrocardiogram hypertension, but the prognostic value of left ventricular hypertrophy (LVH) assessed by electrocardiogram criteria is unknown. MethodsRetrosprospective registry of all patients with chronic coronary syndrome attended in a monographic clinic. We calculated the Cornell index and Sokolov-Lyon index and values> 28 (men) or> 20 (women) were considered for LVH for the first and> 35mm in the second. During follow-up, all-cause or cardiovascular mortality or major cardiovascular events (MACE), considering reinfarction, heart failure, cerebrovascular accident, or major hemorrhage, were evaluated. ResultsA total of 774 patients were included and 60 (8.31%) fulfilled the LVH criteria by the electrocardiogram. The median follow-up was 960 days [interquartile range 538-1586] and during this period 33 (4.6%) patients died, 22 (3.1%) of the deaths were attributable to cardiovascular causes, and 110 (15,2%) patients presented a MACE. In the multivariate analysis, adjusted for age, sex, diabetes, medical treatment and heart rate, both Cornell and Sokolow-Lyon index were linearly associated with a higher risk of death from any cause (HR, 1.11; 95%CI, 1.07-1.16; P> .001), due to cardiovascular causes (HR, 1.11; 95%CI, 1.06-1.17; P> .001) and MACE (HR, 1.04; 95%CI, 1.01-1.06; P=.015). An independent risk was also observed for LVH. ConclusionsLVH, obtained by electrocardiogram criteria, has a high predictive value for mortality and major cardiovascular complications in patients with chronic coronary syndrome.
