[Long-term results of implantation of bioengineered and drug-eluting stents in patients with coronary heart disease: comparative characteristics of predictors of poor prognosis].

ABSTRACT

The purpose of the investigation was to study the morphological and clinical characteristics affecting the long-term prognosis after implantation of bioengineered and drug-eluting stents in patients with coronary heart disease (CHD). The investigation covered 2362 patients with CHD. Genous bioengineered stents were implanted in 316 patients; Cypher rapamycin-eluting stents were in 2046 patients. The independent poor factor for complications was discontinuation of antiaggregatory therapy due to surgical interventions of different types in the drug-eluting stent group and stenting of extensive stenoses in the bioengineered stent group.
