Abstract:
Objective To analyze the predicting value of Cornell-QRS standard and Sokolow-Lyon voltage to left ventricular hypertrophy in hypertensive patients.Methods One hundred and seventy-four patients with primary hypertension were enrolled, who were divided into left ventricular hypertrophy group (LVH group,n=50)and non-LVH group(n=124).The blood pressure, Cornell-QRS standard and Sokolow-Lyon voltage were collected and compared in the following-up period.Results Compared with non-LVH group,in LVH group the history of hypertrophy was longer(P <0.05),percent of grade 3 hypertrophy was higher(P <0.05),and 24 h SBP was higher(P <0.05).During the following-up of 6 months,1 year,2 year,the SBP (systolic blood pressure), DBP (diastolic blood pressure),Cornell-QRS standard and Sokolow-Lyon voltage in LVH patients were all significantly decreased (P <0.01).Compared with non-LVH group,the incidence of non-fatal myocardial infarction and stroke was higher in LVH group[ 3(6.0%)vs .1(0.8%),P <0.05;6 (12.0%)vs .2 (1.6%),P <0.01 ].By Cox analysis,Cornell-QRS standard and Sokolow-Lyon voltage were respectively independent predictors to non-fatal myocardial infarction and also stroke.Conclusion Cornell-QRS stand-ard and Sokolow-Lyon voltage may be independent predictors to main cardiovascular accident in hypertensive patients.
