在其存在的前20年，经皮腔内冠状动脉成形术（PTCA）已成为最常见的主要医疗干预。与此同时，许多不同的介入设备，如钻头、激光器、切割器和吸盘，已经被发明出来，但只有支架（1986年推出）成为PTCA的主要资产。它们的主要益处是减少了夹层导致的急性闭塞的发生率，从而减少了紧急旁路移植术的需要。在介入后3至6个月之间，PTCA的再狭窄率约为30%，支架也将其降低至约20%。从长期来看，即6个月后，支架或非支架病变稳定，仅4%的病变需要血运重建。经皮冠状动脉腔内成形术后，冠状动脉疾病的进展起着主导作用，在多达10%的患者中需要对新狭窄进行后续干预。
In the first 20 years of its existence, percutaneous transluminal coronary angioplasty (PTCA) has emerged to become the most common major medical intervention. In the meantime, many different adjunctive devices, such as drills, lasers, cutters, and suckers, have been invented, but only stents (introduced in 1986) have become a major asset to PTCA. Their main benefit is reducing the incidence of acute occlusions caused by dissection and, thus, the need for emergency bypass grafting. The approximate 30% restenosis rate of PTCA between 3 and 6 months after the intervention is also reduced to approximately 20% by stents. In the long term, ie, after 6 months, the stented or nonstented lesion is stable and needs a revascularization procedure in only 4% of the lesions. After PTCA, progression of coronary artery disease plays a dominant role, necessitating subsequent interventions for new stenoses in as many as 10% of patients.
