The relationship between plasma PDGF-BB level and coronary heart disease and coronary artery stenosis / 天津医药

ABSTRACT

Objective To investigate the relationship between plasma level of platelet derived growth factor-BB (PDGF-BB), coronary heart disease (CHD) and the severity of coronary artery stenosis. Methods A total of 262 patients hospitalized in Department of Cardiology, Tianjin Chest Hospital were collected in this study. According to the medical history, symptoms, laboratory examination and the results of coronary angiography, patients were divided into stable angina pectoris (SAP) group (n=57), acute coronary syndrome (ACS) group (n=119) and normal control group (n=86). The ACS group was divided into three subgroupssingle vessel group (n=38), double vessel group (n=35) and multiple vessel group (n=46). The general clinical data, biochemical parameters and plasma PDGF-BB levels were compared between SAP group, ACS group and control group. Spearman correlation analysis was used to analyze the relationship between PDGF-BB level, high-sensitivity C-reactive protein (hs-CRP) and Gensini scores. Logistic regression analysis was used to analyze the risk factors of coronary heart disease. Results (1) The plasma levels of hs-CRP and PDGF-BB were significantly higher in ACS group than those in control group and SAP group (P0.05). (3) There was no significant difference in plasma level of PDGF-BB between single vessel group, double vessel group and multiple vessel group (P > 0.05). (4) Logistic regression analysis showed that high plasma level of PDGF-BB was the risk factor for coronary heart disease. Conclusion PDGF-BB plasma level is associated with the pathogenesis of coronary heart disease, which may reflect the instability of coronary atherosclerotic plaques, but it is not an index to evaluate the severity of coronary stenosis.
