Abstract

A recent study shows that ADAMTS4 is expressed in macrophage-rich areas of human atherosclerotic carotid plaques and coronary unstable plaques, suggesting a pathogenic role of ADAMTS4 in the development of acute coronary syndrome (ACS). We investigated (a) whether the expression level of ADAMTS4 in plasma and peripheral blood mononuclear cells was affected; and (b) whether there was a relationship with hs-CRP level and the stability of coronary atherosclerotic plaque in patients with ACS. Our study included 30 normal controls and 120 patients including 40 with stable angina (SA), 50 with unstable angina (UA), and 30 with acute myocardial infarction (AMI). The expression of ADAMTS4 in monocytes was analyzed by RT-PCR and plasma ADAMTS4 level was determined by ELISA. All coronary stenosis with >30% diameter reduction was assessed by angiographic coronary stenosis morphology. Patients with ACS showed a significant increase of ADAMTS4 (2.7 ± 0.4) expression in monocytes compared with controls (1.1 ± 0.2) and the SA group (1.3 ± 0.2) (P < 0.001). Plasma ADAMTS4 also showed a higher level in ACS patients (100.2 ± 31.6 ng/ml) than in control (47.5 ± 9.0 ng/ml, P < 0.001) and the SA group (54.3 ± 13.2 ng/ml, P < 0.001). Moreover, we fo...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.
