Abstract

Introduction
Myocardial infarction is one of the most common causes of hospitalization and mortality in human societies. Several researches have performed to identify various risk factors for cardiovascular disease progression and improve treatment methods, medications and therapeutic interventions to minimize mortality. In this study, we have assessed the relation between angiographic findings of patients having myocardial infarction with ST segment elevation and mortality during the hospital course and one month follow up.
Materials and Methods
A total of 156 patients with STEMI Who referred to Imam Reza hospital with the definition of more than 2mm elevation of ST segment in precordial leads and more than 1mm in limb leads also with elevation in cardiac biomarkers were enrolled in this study. Patients’ history obtained and the angiography was carefully reviewed by a cardiologist and variables were recorded. Death of patients during hospitalization and a month after discharge was also recorded.
Results
There was a significant relationship between angiography performance and the presence of thrombus and location of involved vessel, hypotension at presentation, killip class, and tachycardia, hypertension with hospital mortality. Age and calcification were independent factors for one month mortality. In-hospital mortality was 10.3% and one month mortality was 4.3%.
Conclusion
Age and some angiographic factors including the existence of thrombus and anterior wall involvement were significantly correlated with mortality after myocardial infarction.
