title: A novel drug-eluting stent using bioabsorbable polymer technology: two-year follow-up of the CURAMI registry.
abstract: BACKGROUND
  There are safety concerns on drug-eluting stents (DESs) using durable polymer. The long-term outcome of next generation DESs using bioabsorbable polymer technology remains unknown.
  
  
  METHODS
  From March to June, 2005, a novel sirolimus-eluting (170 microg/cm2), bioabsorbable polymer (PLA and PLGA, eroded over 45 days) coated stent was implanted for treatment of acute myocardial infarction (AMI) in 49 patients (male 86%, age 55+10 years, diabetes 31%). All culprits were de novo lesions in the native coronary artery. On discharge, aspirin and clopidogrel for 3 months followed by life-long aspirin were prescribed. Angiographic follow-up was performed at 8 months. Clinical follow-up was performed at 4, 9 and 24 months.
  
  
  RESULTS
  Angiographic success rate was 100%. In-hospital adverse events consisted of 1 death (2%). All except one patient (due to aspirin allergy) were compliant to the 3 months dual antiplatelet therapy, and there was no adverse event during this period. One patient developed re-infarction in another coronary territory at 6 months. Twenty-seven patients (56%) underwent 8-month angiographic follow-up (Table 3). At 24 months, 6 patients had 7 major adverse cardiac events (12.2%, 1 death, 2 re-infarctions and 4 target lesion revascularizations). There were no incidences of subacute or late stent thrombosis.
  
  
  CONCLUSIONS
  The Cura stent, using bioabsorbable polymer technology, appears to be safe at 2 years follow-up. Although the angiographic follow-up parameters were unfavorable, this report paves the way for further studies on DES using bioabsorbable polymer technology.
