Aim: The aim of the present study is to investigate the prognostic value of Coronary Collateral Circulation (CCC) in patients with the first acute anterior wall ST Elevation Myocardial Infarction (STEMI) undergoing primary percutaneous coronary intervention w (p-PCI). Material and Method: A total of 220 Patients with first acute Anterior STEMI within first 6th hours undergoing p-PCI were divided into 2 groups with respect to absence of CCC and presence of CCC. Coronary collateral flow to the infarct related artery (IRA) was graded on baseline angiograms with the use of qualitative classification by Rentrop. Results: A total of 220 patients mean age was of 61.4±12.3 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.
