Comparison of creatine kinase elevation and outcome of comparison of percutaneous coronary intervention for saphenous vein graft in-stent restenosis versus de novo stenosis

Percutaneous coronary intervention of saphenous vein grafts is associated with distal embolization. We aimed to compare potential differences in patients undergoing percutaneous coronary intervention for in-stent restenosis with de novo saphenous vein graft lesions. Myocardial necrosis was associated with higher mortality regardless of lesion type.
