عنوان انگلیسی Comparison of the Coronary Vessel Diameter During and After Primary Percutaneous Intervention in Patients with Acute Myocardial Infarction
چکیده انگلیسی مقاله Background: An increase in the plasma levels of catecholamines and other neurohormones afteracute myocardial infarction (AMI) leads to coronary vasoconstriction and may cause theundersizing of stents during primary percutaneous coronary intervention (PCI) in STsegment elevation myocardial infarction (STEMI). We aimed to compare the referencevessel diameter of the infarct-related artery during and after primary PCI in patients withAMI.Methods: This prospective interventional study was performed on 43 consecutive patients withSTEMI (TIMI flow grade III), who were candidated for primary PCI. The main proximaldiameter of the coronary artery (reference vessel diameter) was assessed at baseline and also3 days to 3 months after 2nd angiography. The study end point was to compare the referencevessel diameter within and after primary PCI.Results: Comparison between the mean diameter of the involved coronaries after PCI and the meandiameter during the procedure showed a significant increase in the real size of the rightcoronary artery (RCA) and a slight decrease in the size of the left circumflex artery (LCx).However, the mean sizes of the left anterior descending coronary artery remainedinsignificant. The decrease in the LCx diameter and inversely the increase in the RCAdiameter remained significant in the study population even after adjusting cardiovascularrisk factors as potential confounders.Conclusions: The changes in the diameter of the reference coronary arteries, namely an increase inthe RCA diameter and a decrease in the LCx diameter, are expected following primary PCIin patients with STEMI.
