Background: Patients with non-ST-segment elevation myocardial infraction are at risk of adverse cardiac events like death, CHF, re-infarction, stroke, major bleeding, cardiogenic shock, acute pulmonary edema and arrythmias. We aimed to investigate the outcome of early vs. late intervention in patients with non-ST-elevation myocardial infraction. Aim: To investigate the outcome of early vs. late intervention in patients with non-ST-elevation myocardial infraction. Subjects and methods: 100 eligible NSTEMI patients were included in our study and were divided into 2 groups: Group I “Early Intervention" 50 patients with door-to-balloon time < 24 hours and Group II “Late Intervention" 50 patients with door-to-balloon time >24 hours. All patients were assessed for baseline characteristics, admission data, ECG, echocardiography, angiographic data in-hospital outcome & 3 months follow up outcome. Results: An early-intervention strategy did not differ from a delayed-intervention strategy in preventing a composite outcome of death, myocardial infarction, heart failure, cardiogenic shock, acute pulmonary edema, major bleeding stroke and arrythmias. Conclusion: Early invasive approach compared with a delayed invasive approach in patients with Non-STEMI does not improve survivalBackground: Patients with non-ST-segment elevation myocardial infraction are at risk of adverse cardiac events like death, CHF, re-infarction, stroke, major bleeding, cardiogenic shock, acute pulmonary edema and arrythmias.
