Multiple overlapping drug-eluting coronary stents (DES) are usually needed to treat long coronary stenoses but this strategy is expensive and the response to overlapping DES has not been extensively studied. The recent availability of bioabsorbable polymer DES could allow treatment of long coronary stenoses without leaving gross burden of non-absorbable polymer in the vessel wall, even in case of overlapping stents.

Thus we planned to evaluate which of the 2 strategies, namely using a single long biabsorbable DES or two shorter biabsorbable DES with minimal overlapping, is better in treating long coronary stenoses.

The study is a spontanous randomized multicenter open-label study. A maximum of 300 patients with stable angina and at leat 1 coronary stenosis >28mm and <40mm of length will be randomized in 1:1 fashion by a Web-based electronic CRF. The long stent group (Group A) will be treated by a single 44mm Biomime DES (II generation DES with bioabsorbable polymer, Meril Life Sciences Pvt. Ltd., Gujarat, India). The short stent group (Group B) will be treated by 2 short Biomime DES positioned with minimal overlapping. The primary end-point of the study will be the 6 moth in-stent late lumen loss. Seconadry end-points will be 1, 6 and 12 month overall mortality, myocardial infarction, target vessel revascularization, stent thrombosis and MACE (combination of the 3 previous clinical end-points). Patients will be evaluated by 6-month control coronary angiography and late lumen loss in the stented vessel will be measured in a quantitative coronary angiography Core Lab (Cardioimaging Centre, Novara, Italy)

Further study details as provided by Azienda Ospedaliero Universitaria Maggiore della Carita:

Primary Outcome Measures:
  • follow up in-stent late lumen loss [ Time Frame: 6-month ]
    difference between the in-stent coronary lumen measure obtained immediately after coronary percutaneous intervention and the in-stent coronary lumen measure at follow up

Secondary Outcome Measures:
  • overall mortality [ Time Frame: 1 year ]
    mortality for all causes

  • Myocardial infarction [ Time Frame: 1 year ]
    Myocardial infarction (universal definition of myocardial infarction, ACC/AHA/ESC statement) in the territory of the treated coronary artery

  • target vessel revascularization [ Time Frame: 1 year ]
    revascularization of the treated coronary vessel by repeated percutaneous coronary intervention or coronary artery bypass grafting due to restenosis and or symptoms or instrumental signs of myocardial ischemia

  • Stent thrombosis [ Time Frame: 2 years ]
    Coronary stent thrombosis according to ARC definition

  • MACE (major coronary adverse event) [ Time Frame: 1 year ]
    combined endpoint = presence of overall death or myocardial infarction or target vessel revascularization or stent thrombosis

Estimated Enrollment: 300
