Comparative Study Clinical Trial
Comparison of primary balloon angioplasty with bailout stenting strategy to primary coronary stenting strategy in the treatment of patients with ST-segment elevation myocardial infarction (STEMI).
In recent years significant progress has been made in invasive treatment of patients with acute myocardial infarction (AMI). Primary coronary stenting is currently a routine strategy which replaced primary balloon angioplasty with bailout stenting preferred in the past. Studies comparing these two strategies of stenting in AMI are scarce. ⋯ 1. Effectiveness of coronary angioplasty is high and comparable in both groups. 2. In-hospital and long-term mortality and procedure-related complication rate are all low and comparable with both stenting strategies. 3. Independent factors increasing long-term mortality include: culprit vessel reocclusion, multivessel coronary disease, older age and hypertension. 4. Patients with complete patency of culprit vessel restored and with higher left ventricular ejection fraction presented lower 2-year mortality rate. 5. Bailout stenting did not increase 2-year mortality.
