Abstract:
Objective: To investigate the relationship between blood level of Galectin-3 and the severity of coronary lesions in patients with coronary artery disease (CAD). Methods: A total of 158 consecutive subjects received coronary artery angiography (CAG) in Yantai Yu huangding hospital were studied and they were divided into 2 groups: Control group,n=38 individuals with normal coronary artery, CAD group,n=120 patients with at least 1 coronary branch stenosis ≥ 50%. CAD group was further divided into 2 sets of subgroups:①By the number of branches involved, as Single vessel disease, n=42, Double vessels disease including LM,n=40 and Triple vessel disease,n=38.②By the quartile of Gensini score as 1st quartile group, the patients with Gensini score ≤ 18.5, 2nd quartile group,18.5 < Gensini score ≤ 45.0, 3rd quartile group, 45.0 < Gensini score ≤ 71.5 and 4th quartile group, Gensini score>71.5,n=30 in each subgroup. Blood levels of Galectin-3 were examined, and the severity of coronary lesions was evaluated by both branch numbers and Gensini score analysis. Results: Compared with Control group, the blood level of Galectin-3 was higher in CAD group,10.66 (5.81, 16.17) ng/ml vs 18.3(1.14, 2.52) ng/mlP<0.01; with the more branches of coronary lesions involved, the blood levels of Galectin-3 increased accordingly, all P <0.01. With the elevation of Gensini score, the levels of Galectin-3increased accordingly, except for the difference between the 3rd quartile group and 4th quartile group, all P <0.01.With adjusted other factors, blood levels of Galectin-3 were positively related to the number of coronary branchlesions (r =0.52, P <0.01) and Gensini score levels (r =0.17, P =0.04).Conclusion: Blood level of Galectin-3 is positively related to the severity of coronary lesions whichimplies that Galectin-3 may have potential detrimental effect on the occurrence and development of coronaryatherosclerosis.
