Correlation between obesity and prethrombotic state in patients with coronary heart disease / 心血管康复医学杂志

ABSTRACT

Objective: To explore the correlation among overweight, obesity and markers of prethrombotic state in patients with coronary heart disease (CHD). Methods: A total of 288 patients to hospital from 2013 to 2014 and diagnosed as CHD by coronary angiography were selected. According to body mass index (BMI), they were divided into CHD control group (n=106), overweight group (n=121) and obesity group (n=61). Levels of fibrinogen (Fg), plasma D dimmer (D-D), von Willebrand factor (vWF), antithrombin Ⅲ (AT-Ⅲ) and plasminogen activator inhibitor (PAI)-1 were compared among three groups, then received correlation analysis.Results: Compared with CHD control group, there were significant rise in levels of triglyceride, total cholesterol, fasting blood glucose and mean arterial pressure, morbidity rates of hypertension and diabetes mellitus in overweight group and obesity group, P<0.05 or <0.01. Compared with CHD control group, there were significant rise in levels of Fg [(2.89±0.60) g/L vs. (3.54±0.63) g/L vs. (3.92±0.94) g/L], D-D [(282.13±73.15) ng/ml vs. (390.04±73.54) ng/ml vs. (471.92±80.38) ng/ml], vWF [(108.62±24.66)% vs. (138.45±25.96)% vs. (161.20±29.39)%] and PAI-1 [(6.97±1.28) ng/ml vs. (9.60±1.73) ng/ml vs. (12.33±2.16) ng/ml] in overweight group and obesity group, P<0.01 all, and those of obesity group were significantly higher than those of overweight group, P<0.01 or <0.05; AT-Ⅲ level [(89.94±17.99)% vs. (69.89±20.22)%] significantly reduced in obesity group (P<0.05). Pearson correlation analysis indicated that BMI was positively correlated with markers of prethrombotic state [Fg r=0.536, P<0.001; D-D r=0.250, P<0.001; vWF r=0.611, P<0.001;PAI-1 r=0.788,P<0.001). Conclusion: BMI is positively correlated with markers of prothrombotic state in CHD patients.
