Long-term results of percutaneous transluminal coronary angioplasty and coronary artery stenting: five-year follow-up

Abstract

Aim. To compare long-term results of coronary artery (CA) angioplasty and stenting, according to baseline CA stenosis morphology. To assess clinical course of coronary heart disease (CHD) during long-tem follow-up after endovascular intervention. Material and methods. During 1989-2005, 228 males with angioplasty and 184 males with non-eluted CA stents were recruited. One year later, 358 patients were examined, 5 years later - 273. Results. At five years after endovasular intervention, comparing to baseline and one-year results, the number of patients without angina symptoms substantially decreased, and the number of participants with angina increased. Long-term restenosis incidence was affected by initial CA stenosis morphology. In С Type, comparing to A Type, restenosis developed more often, by 2-2,5 times, regardless of endovascular intervention type. Conclusion. Choosing the therapeutic tactics in CHD, initial CA stenosis morphology should be taken into account. Stenting is more effective than angioplasty, especially in С Type pathology.
