Current practice of percutaneous coronary intervention on patients with acute coronary syndrome in Iran: A prospective observational study.

Abstract

Background: Frequent Percutaneous Coronary Intervention (PCI) procedures are being performed on a daily basis in Iran. However, no study has been reported on the current PCI practice in patients with acute coronary syndrome (ACS) in Iran. We aimed to describe the clinical characteristics and treatment patterns in Iranian ACS patients treated with PCI. Methods: Between February 2017 and July 2017, ACS patients presented to 5 referral hospitals in two major cities of Iran (Tehran and Shiraz) were included in this observational study if aged > 18 years and underwent PCI for ACS during hospitalization; and their clinical and procedural characteristics were collected. All data were entered into SPSS v.21 and descriptive statistics were performed. Results: Of a total of 314 patients, 228 (73%) were males, 162 (52%) were diagnosed with ST-elevation myocardial infarction and 152 (48%) with Unstable angina/ Non-ST elevation myocardial infarction. Trans-femoral approach was more often (64%) used for PCI procedures. Stent placement was the most frequent (98%) treatment strategy on PCI, with drug-eluting stent selected in the majority of subjects (98%). The overall rate of PCI success was 95%, with 4.1% PCI-related complications, and 1.6% post-PCI bleeding events. The vast majority of the study patients (99%) were discharged with dual anti-platelet therapy. Conclusion: In this study, we observed a high level of adherence to the currently accepted guidelines in the current PCI practice on ACS patients in Iran. Also we found our practice is highly in line with the global reduction trend in the PCI-related complications.
