Title

A Study about the relation between QTC interval and 3-days mortality in admitted patients with acute myocardial infarction in Ardabil Bouali Hospital

English Abstract

Introduction: There are some factors that may enhance the mortality rate of patients with AMI like the size of infarct zone, left ventricule ejection farction, ventricular hypertrophy, and… . Also it is said that the prolohged QT interval may increase the mortality rate of AMI.The aim of this study was to evaluate the effect of QT interval in 3-days mortality rate of patients with AMI admitted in Ardabil Bouali Hospital. Methods and Materials: This study was performed in prospective, descriptive and cross-sectional manner in patients with AMI, admitted in CCU section in Ardabil Bouali Hospital and after the collection of needed data in special forms, they were analyzed with statistical metods like SPSS. The patients with electrolyte abnormalities or using the drugs that had effect on serum calcium level were omitted from this study. Results: From 100 patients , 72 persons (72%) were male and 28 persons (28% )were female. The mean age of patients was 64.04 years. 57% of patients had anterior AMI and 43% had inferior AMI. Also,in 42% of patients, streptokinase was used. From all of 100 patients, ventricular tachyarrhythmia accured in 17 patients. 8% of patients were expired in first 3 days of the admission in the hospital, that 5 persons of them had ventricular tachyarrhythmia. The average QTc interval in first 3 days in all of the patients was 475 ms. Also, the mean QT dispersion of these patients was 77ms and this criteria increased slowly in the days of admission. Conclusion: In this study the QTC interval was prominently prolonged in the patients with AMI. Also patients with ventricular tachyarrhythmia had longer QTC interval than patient without ventricular tachyarrhymia. In women, the QTC interval wsa longer than men. This study showed that AMI prolongs the QTC interval and the prolongation of QT interval is a risk factor for occurance of ventricular tachyarrhythmia and increasing mortality rate in patients with AMI.
