Evaluating Plasma Galectin-3 Levels in Patients With an Increased Risk of Atherosclerotic Cardiovascular Disease Who Underwent Coronary Artery Revascularization

Coronary artery disease (CAD) is a common atherosclerotic cardiovascular disease (ASCVD) associated with significant mortality. Galectin-3 is a novel inflammatory factor implicated in the initiation and progression of atherosclerosis. We aimed to evaluate the association of plasma galectin-3 with the risk of ASCVD and the need for coronary artery revascularization. Patients with angina who underwent coronary angiography were divided into groups per their risk of ASCVD. Patients (n = 385) were stratified into having low (n = 21), moderate (n = 40), high (n = 41), and very high risk (n = 283) for ASCVD. The mean age ± standard error of the mean was 53.9 ± 0.5 years and 73% of patients were men. Plasma galectin-3 levels were higher in patients with CAD than non-CAD primarily in patients with stable and unstable angina. Patients with stable CAD had higher levels of galectin-3 relative to acute coronary syndrome patients. Increased plasma galectin-3 level was associated with increased risk of ASCVD and degree of coronary stenosis. By multivariate analysis, the plasma galectin-3 level was independently associated with increased ASCVD risk and body mass index. Plasma galectin-3 levels were independently higher in patients who underwent percutaneous coronary intervention (PCI) than medically treated patients. In addition, age, male gender, smoking, and diabetes mellitus were associated with PCI. In conclusion, plasma galectin-3 levels are elevated in patients with CAD and associated with increased risk of ASCVD and the need for PCI. Plasma galectin-3 could be used as a potential improving predictor of ASCVD risk and when making therapeutic guidance or selecting patients who underwent PCI when the decision is difficult.
