The Relationship Between Coronary Collateral Circulation and In-hospital Mortality in Patients with First Acute Anterior STEMI

Results: A total of 220 patients mean age was of 61.412.3 years with first acute Anterior STEMI undergoing p-PCI were included the study. 34% of patients had CCC. The present study consisted of 64 female (29%) and 156 male (71%) patients. There were no statistically significant differences in respect to demographic characteristics, risk factors of coronary artery disease, LVEF, KILLIP classes, time from symptomps onset to PCI, door to baloon time, preprocedural and postprocedural angiographic characteristics and clinical outcomes which included cardiogenic shock on admission, cardiogenic shock in-hospital, fatal ventricular arrhtymias, complet AV block, mechanical complications and in-hospital mortality between the groups. In a stepwise backward multivariable logistic regression model, the independent prognostic indicators for in-hospital mortality were age (odds ratio [OR] 1.08, 95% CI 1.07 to 1.26, p=0.03), Time from symptoms onset to PCI (odds ratio [OR] 1.6, 95% CI 1.06 to 2.59, p=0.04) and unsuccessful p-PCI (odds ratio [OR] 3.3, 95% CI 1.04 to 10.9, p=0.04). Conclusion: Presence of CCC was not associated with in-hospital mortality in patients presenting with first acute Anterior STEMI undergoing p-PCI within first 6th hours.
