Abstract

The present study aimed to investigate whether non-culprit coronary lesions (NCCLs) in young patients (<45 years) who underwent percutaneous coronary intervention (PCI) with stents have higher rates of atherosclerotic progression than older patients. Eight hundred and forty-eight consecutive patients who underwent successful PCI with stents and second coronary angiography in a single center from January 7, 2008 to May 7, 2013 were enrolled. NCCL progression was assessed using three-dimensional quantitative coronary angiography and was defined as ≥ 10% diameter reduction of preexisting stenoses of ≥ 50%, ≥ 30% diameter reduction of <50% stenoses, development of a new stenosis of ≥ 30% in a previously normal segment, or progression to total occlusion. The mean time interval between two catheterization was 10.79 months; 136 (16.0%) patients exhibited progression of NCCLs. Multivariate Cox regression analysis (stepwise) showed young age to be an independent determinant of NCCL progression. Compared with the older patients(≥ 45 years), the crude hazard ratio (HR) for NCCL progression in the young patients(<45 years) was 2.17 (95% CI 1.42-3.30; P < 0.001); the association remained significant after adjustment for sex, ST elevation my...Continue Reading

Atherosclerosis Disease Progression

Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.
