Evaluation of hs-CRP and IVUS on major adverse cardiac event in patients with after coronary artery intermediate lesions stent implantation

Abstract

Objective To investigate the impact of hs-CRP and IVUS on major adverse cardiac event in patients who after coronary artery intermediate lesions stent implantation.Methods 82 patients with clinical diagnosis of coronary heart disease who had a segmental stenosis degree is 40％ ～ 70％ in one major coronary artery on coronary angiography,all of the patients do intravascular ultrasound,patients had minimal lumen area(MLA) of intermediate lesions ≤ 4mm2( the left main coronary artery)or≤ 6mm2( left main coronary artery) who received percutaneous coronary intervention(PCI),and the patients were divided into 2 groups,hs-CRP rise group(≥3mg/L) and hs-CRP normal group(＜3mg/L),compared the rate between the two groups in hospital and follow up periods by typical angina,nonfatal myocardial infarction,cardiac death and target-vessel revascularization and other major adverse cardiac events (MACE).Results The rate on major adverse cardiac event in hs-CRP rise group was significantly higher than the normal group(P ＜0.01 );the restenosis rate in hs-CRP rise group higher than hs-CRP normal group(P ＜0.01 ).Conclusion hs-CRP could predict the rate on major adverse cardiac event in patients with after coronary artery intermediate lesions stent implantation,the patients of hs-CRP rise group should strengthen antiplatelet,anti-inflammatory treatment etc. Key words: Coronary heart disease; C-reactive protein; Coronary angiography
