Summary: | The main culprit in first-generation drug eluting stents is 'durable' polymer, whose continuous presence may impair arterial healing and ultimately have a negative impact on late outcomes. The main enigma behind the biodegradable polymer usage is its degradation after elution of drug. This reduces adverse events in unselected patients with complex coronary artery lesions treated with biodegradable polymer coated sirolimus-eluting stents.
The aim of the INDOLIMUS-G Registry was to evaluate safety and efficacy of the Indolimus (Sahajanand Medical Technologies Pvt. Ltd., Surat, India) sirolimus-eluting stents in large cohorts of unselected patients with complex coronary artery lesions.
It is a multi-centre, non-randomized retrospective registry with a clear aim of evaluating safety and efficacy of the Indolimus sirolimus-eluting stents in consecutive patients enrolled between April 2012 and May 2014. The primary end-point of the study was major adverse cardiac events (MACE), which is a composite of cardiac death, myocardial infarction (MI), target lesion revascularization (TLR), target vessel revascularization (TVR) and stent thrombosis (ST) at the end of follow-up. Clinical follow-up were scheduled at the end of 30-days, 6-months, and 9-months period.
The mean age of enrolled patients was 52.6 ± 11.0 years. A total of 1137 lesions were intervened successfully with 1242 stents (1.09 ± 0.30 stent per lesion). The average stent length and diameter was 27.42 ± 9.01 mm and 3.12 ± 0.36 mm respectively. There were 740 (73.40%) male patients, indicating their high prevalence. Diabetes, hypertension and totally occluded lesions were found in 372 (36.90%), 408 (40.47%) and 170 (16.86%) patients, respectively. This showed that study also included high risk complex lesions and not ideal recruited lesions. The incidence of MACE at 30-days, 6-months and 9-months were 3 (0.30%), 18 (1.80%) and 22 (2.20%) respectively. At 9-months, TLR was found in 6 (0.50%) patients. There were 2 (0.20%) cases of ST, 10 (1.0%) cases of MI and 4 (0.40%) cases of cardiac death at 9-month follow-up.
The lower incidence of MACE, TLR and ST at 9-month follow-up clearly delineates safety and efficacy of Indolimus SES in large cohorts of unselected patients with complex coronary lesions. |
