Galectin-1, a ß-galactoside-binding lectin, was reported to attenuate the cardiac inflammation and ventricular remodeling after AMI. Its role in stable CAD was not fully elaborated. This study aimed to identify the relationship between galectin-1 and severity of CAD in patients with stable angina.
Totally 834 subjects underwent elective CAG were enrolled. Pre-procedure galectin-1 and hsCRP concentrations were determined. Subjects were grouped into tertiles according to their galectin-1 concentrations. SYNTAX scores were calculated to evaluate the severity of CAD. All patients were followed until January 2019, or the occurrence of major adverse cardiovascular events (MACE).
Patients with higher galectin-1 concentrations were older and had higher prevalence of hypertension, diabetes, heart failure, and with higher levels of hsCRP and STNYAX scores. Patients with the highest tertile of galectin-1 were associated with higher risk of MACE (Fig 1A), even after adjusting age, gender, hypertension, diabetes, hemoglobin, creatinine, and LVEF (aHR: 2.13, 95% CI: 1.04-4.33, p=0.038). Gelection-1 (AUC: 0.802) showed better discriminatory performance than hsCRP (AUC: 0.696) in prediction the incidence of MACE (Fig 1B).
Serum galectin-1 levels were associated with the severity of CAD and subsequent MACE in patients with stable angina.
