Abstract:

Objective The majority of cardiovascular events in patients undergoing percutaneous coronary interventions (PCI) arise from the progression of non-culprit coronary lesions (NCL) during the follow-up period. The purpose of this study was to investigate the predictors related to the rapid progression of NCL of patients undergoing PCI. Methods Between Jan. 2006 and Apr 2011, 170 consecutive patients who underwent coronary angiograms again with a time interval from 1 to 12 months after successful stent implantation at culprit-lesion. The patients were divided into rapid progression group (n=49) and slow progression group (n=121) according to definition of rapid progression. Results Twenty-eight percent of patients had rapid progression of non- lesions. Rapid progressors had higher percentage of multivessel diseases and statin therapy. At follow-up, a significant difference was observed between rapid progression group and slow progression group in triglyceride (TG) (2.02 vs 1.59 mmol/L, P=0.020), total cholesterol (TC) (4.25 vs 3.79 mmol/L, P=0.013), and change of TC (-0.80 vs -1.25 mmol/L, P=0.03), low-density lipoprotein cholesterol (LDL-C) (2.42 vs 2.16 mmol/L, P=0.03) and change of LDL-C (-0.39 vs -0.75 mmol/L, P=0.020). Multivariate Logistic regression analysis revealed that multivessel diseases, on-treatment for TG, change of LDL-C, rate of in-stent restenosis and rate of statin therapy were independent predictors for rapid progression. Conclusion Multivessel diseases, on-treatment for TG, change of LDL-C, rate of in-stent restenosis and rate of statin therapy were associated with the rapid progression of non- coronary lesion. This finding highlights the need for intensive statins therapy in patients with coronary artery disease after successful PCI.
