What are the benefits of primary stent implantation compared to primary balloon angioplasty for acute myocardial infarction?
A meta-analysis of randomized clinical trials has shown that primary stent implantation has several benefits over primary balloon angioplasty for acute myocardial infarction. These benefits include improved reperfusion, fewer distal embolizations, and improved outcomes in terms of reduced mortality, reinfarction, and subsequent revascularization. In addition, primary stent implantation has a lower risk of abrupt closure, transient ischemia, and distal embolization compared to balloon angioplasty, and there is also a decreased risk of in-stent restenosis with primary stent implantation.
