There is still a lack of data on the influence of different stent designs on long-term restenosis rates and major adverse cardiac events (MACE) with the use of new antithrombotic regimens. We evaluated the midterm (6 months) clinical and angiographic and lateterm (2 years) clinical outcome of Helistent stent implantation.
The study population consisted of 150 patients with high risk factor rates who had single or multivessel disease and had undergone coronary Helistent stent implantation with new antiplatelet regimens. The control coronary angiographies were done at 6 months and they were followed clinically to the end of 2 years.
In 150 patients, 236 Helistent stents were implanted for 224 lesions. Helistent stent implantation was associated with a very high success rate (99%). The angiographic re-stenosis rate was 11.3% at 6 months. Only 16% of the patients experienced target lesion revascularization, 20% of the patients experienced MACE and of them, only 3.3% died at the end of two year follow-up period.
The results demonstrate that the Helistent stent can be implanted with a high success rate with encouraging 6 month angiographic and late clinical outcomes.
