ABSTRACT
BACKGROUND:
Little is known about the impact of stent type on the prognosis of vasospastic angina (VSA) in patients who undergo stent implantation.MethodsâandâResults:
We evaluated consecutive patients undergoing coronary angiography with positive (n=650; VSA) and negative (n=2,872; non-VSA) ergonovine testing. Among them, 304 patients undergoing stent implantation for organic stenosis were classified for comparison into 3 respective VSA and non-VSA groups based on stent type (68 and 78 with bare-metal stent [BMS]; 21 and 49 with sirolimus-eluting stent [SES]; 26 and 62 with newer generation drug-eluting stent [N-DES]). The primary outcome was defined as target lesion revascularization, target vessel revascularization, emergency coronary angiography, and cardiac death. The 2-year cumulative incidence of the primary outcome was significantly higher in the VSA group than non-VSA group after SES implantation (38.1% vs. 16.1%, P=0.03), whereas there were no differences between the 2 groups after both BMS implantation and N-DES implantation. The difference in the percent diameter stenosis from mid-term to late-term follow-up was significantly higher in the VSA group than non-VSA group (10.0% vs. 2.3%, P=0.045) after SES implantation, whereas there were no differences between the 2 groups after both BMS implantation and N-DES implantation.CONCLUSIONS:
The impact of VSA on clinical and angiographic outcomes was observed only in SES implantation, but not after N-DES or BMS implantation.Palavras-chave
