Özet
The ACS Multilink (ML) stent is a novel second-generation stent. The largest amount of information available on the long-term outcome of coronary stenting is based on the use of Palmaz-Schatz stents. Fewer data exist on long-term follow-up results of ML coronary stents implantations. The authors present the long-term (>3 years) clinical and angiographic follow-up results of the ACS Multilink coronary stents implanted in their institution. From May 1996 to December 1997, 125 patients underwent 133 coronary ML stent implantations. Stented vessels were as follows: 49% left anterior descending artery, 31% right coronary artery, and 20% left circumflex coronary artery. Indications for stent implantations were elective in 64%, because of suboptimal result from percutaneous transluminal coronary angioplasty (PTCA) in 26%, and bailout from PTCA in 10% of patients. The mean reference diameter of stented vessels was 3.2 ±0.2 mm. The mean percentage stenosis was 80 ±11% and 3 ±5% before and after stent implantation, respectively. Long-term clinical follow-up was completed in 75% (80 men, mean age 53 ±10 years) of the patients (either by interview or phone), and angiographic follow-up (37 ±12 months) was completed in 58% of the patients. There were no baseline clinical or angiographic differences between those angiographically followed up and the remaining patients. Angiographic restenosis (>50% diameter stenosis) was detected in 22% of stents. Target lesion revascularization was 12%, nontarget lesion revascularization was 14% in angiographically followed up patients. During the follow-up period death and new myocardial infarction occurred in 12% and 6% of patients, respectively, and survival rate was 88%. This study provides long-term follow-up results of intracoronary Multilink stent implantations for native coronary artery lesions. These data show that clinical and angiographic benefits of ML stents are comparable to those of the first-generation stents, especially to the Palmaz-Schatz stents, of which results have been reported previously. A considerable rate of nontarget lesion revascularization occurs during the follow-up period.
