Abstract

To analyze Osteoprotegerin (OPG), and BNP plasma levels in patients with non-ST elevation acute coronary syndrome (NSTE-ACS), in relation to clinical presentation and to coronary atherosclerosis diffusion. 155 CAD patients were classified in four groups: stable angina (SA n=42), unstable angina (UA n=35) non-ST elevation myocardial infarction (NSTEMI n=45) and control group (n=33), measuring OPG and BNP at hospital admission. We compared both biomarkers in relation to the number of coronary narrowed vessels (1-,2-,3 or more vessels disease), and to the stenoses degree by Duke Jeopardy score. OPG levels were higher in patients with CAD respect to controls (p<0.0001). Patients with SA showed more elevated levels than controls (2.6+/-1.2 vs 7.4+/-5.0 pmol/l p<0.01). However patients with UA and NSTEMI had higher OPG level with respect to SA patients (12.2+/-7.8 and 11.6+/-6.1 respectively pmol/l p<0.001). A positive relation was found between OPG levels and coronary plaques extension by Duke Jeopardy score (r=0.65). BNP levels were higher in patients with UA/NSTEMI respect to controls and SA patients (p<0.001). Besides, BNP was significantly higher in patients with multi-vessels vs 1-vessel disease (p<0.001). Patients with UA and ...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.
