The Effect of Left Ventricular Hypertrophy in ECG on Hospital Mortality of Patients with ST Segment Elevation Myocardial Infarction undergone Primary Angioplasty

Abstract

Coronary artery disease is the most important cardiovascular disorder. Considering the increasing prevalence of STE-MI and health care costs and its clinical consequences and considering that left ventricular hypertrophy is one of the relatively common cases in these patients, the present study aimed to determine the effect of left ventricular hypertrophy on ECG on Patients with nosocomial mortality with a diagnosis of myocardial infarction underwent ST-segment elevation underwent primary angioplasty. Materials & Methods: In the present study, 341 patients who underwent ST-segment diagnosis in Shahid Madani Hospital of Tabriz University of Medical Sciences from 2013 to 2017 and underwent primary angioplasty were included in the study and then Patients were divided into two groups based on electrocardiogram: left ventricular hypertrophy and without left ventricular hypertrophy. Left ventricular hypertrophy was defined as S amplitude V1 + R amplitude V5 or V6 ≥35 mm. Both groups were compared in terms of demographic criteria, risk factors, clinical symptoms, vital signs, laboratory tests, hospital mortality and one-year mortality. Results: In the present study, 341 patients were included in the study. The mean and standard deviation of age in the group of patients without left ventricular hypertrophy was 11.64 57 57.95 and in the group of patients with left ventricular hypertrophy was 64.60 ± 10.480. Was (p = 0.013). Also, sex with a higher frequency of men in the group of patients without left ventricular hypertrophy was significantly different between the two groups (p = 0.013). Among the risk factors for hypertension in the group of patients with left ventricular hypertrophy was significantly higher than the other group (p < 0.001). Patients in the two groups were not significantly different in terms of the presence of other risk factors (p> 0.05). Among the ECG findings of patients with left heart axis deviation in the group of patients with left ventricular hypertrophy with 95% incidence was significantly higher than the group of patients without left ventricular hypertrophy with 65% incidence (p> 0.05). Among the angiographic findings of patients, the multivariate obstruction (MultiVD) variable was statistically significant between the two groups, so that this variable with a prevalence of 70% in the group of patients with left ventricular hypertrophy had a higher frequency than the group of patients without left ventricular hypertrophy (45.8%). ) Had (p = 0.036). Other vital sign variables, laboratory findings, echocardiographic findings and mortality and morbidity variables were not significantly different between the two groups of patients (p> 0.05).
