Many studies have shown that a sirolimus-eluting stent (SES) decreases restenosis and target leision revascularization (TLR). We investigated the outcome of SES in a general hospital in Nagano, Japan.
The study group consisted of 99 patients with 127 lesions. We retrospectively evaluated the stent thrombosis and major adverse cardiac events (MACE) in the lesions of the entire study group. For evaluation of the stent and segment restenosis, follow up angiography was performed in 69 patients with 87 leisions.
During follow up, a MACE occurred in 8 patients (cardiac death in 2 and TLR in 6 of 99 patients). One cardiac death was due to coronary spasm just after stent implantation, and the other to very late stent thrombosis. There were 8 segment restenoses, which included 4 stent restenoses.
The outcome of SES in our hospital was comparable to that reported by other Japanese institutes. Additional research is required to avoid coronary spasm after placement of a drug-eluting stent.
