Frequency of Acute Stent Thrombosis after Primary Percutaneous Coronary Intervention in Patients with ST-Elevation Myocardial Infarction

Objective: To determine the frequency of acute stent thrombosis after primary percutaneous coronary intervention in patients with ST-elevation myocardial infarction. Study Design: Descriptive cross sectional study. Place and Duration Study: Department Cardiology, National Institute Cardiovascular Disease Hospital, Karachi from 30th 2017 to 31st December 2017. Methodology: One hundred sixty three will undergo either drug-eluting stents (coated medication) or bare-metal was placed. Patients who developed sudden onset typical chest pain, indicating ischemia distribution target vessel (in which placed), these patient’s angiography done (relooked) if it showed complete occlusion within stented segment evidence thrombus, patient labeled as having thrombosis. Results: There were 117 (71.7%) males 46 (28.23%) females mean age 51.78±13.09 years. Drug-eluting placed 87(53.37%) bare metal 76(46.63%) patients. Positive 2 (1.23%). Conclusion: The PCI found be 1.23%. Keywords: infarction (STEMI), Percutaneous (PCI), Acute infarction, Stent
