The effectiveness of stenting in patients with angina recurrence after coronary artery bypass grafting. The results of the 3-years prospective study

The long-term effectiveness of the endovascular angioplasty after coronary artery bypass grafting (CABG) in patients with angina recurrence was studied. It was revealed that seventy one month after CABG the closure of bypasses (autovenous 58.1% and arterial 46.2%) and/or hemodynamically significant coronary artery (CA) stenosis de novo (88.2%) led to the increase in coronary insufficiency. Three years after repeated revascularization using native CA stenting and shunts stenting the decrease in the angina pectoris severity, the increase in the exercise stress tolerance, the regression of left ventricle remodeling and cardiac hemodynamics improvement were noted. The repeated endovascular revascularization in patients of such risk group is highly effective and safe. And its clinical effectiveness is comparable with primary CA stenting (67.6%).
