Objective: To observe assessment effects of thromboelastogram (TEG) on patients with coronary heart disease (CHD) complicated hypertension.Methods: A total of 120 CHD patients were selected from our hospital.According to complicated with hypertension or not, they were divided into pure CHD group (n=58) and CHD + hypertension group (n=62).TEG indexes were compared between two groups.Results: Compared with pure CHD group, there were significant reductions in blood clot formation duration [K: (2.53±0.72)min vs.(1.82±0.64)min], coagulation reaction duration [R: (8.66±1.86)min vs.(7.18±1.85)min], arachidonic acid pathway-induced platelet activity [AA: (57.36±16.91)% vs.(46.73±20.73)%], and significant rise in maximum amplitude after clot formation [MA: (57.31±7.75)mm vs.(64.36±7.85)mm] and included angle value between the tangent from the blood clot forming point to the maximum curve radian of the chart and the horizontal line [Angle: (53.26±7.78) vs.(64.38±7.85)] in CHD + hypertension group, P<0.01 all.Spearman correlation analysis indicated that blood pressure level was significantly positive correlated with Angle and MA (r=0.607, 0.405, P<0.01 both), and significantly inversely correlated with R and K (r=-0.256,-0.541, P<0.01 both) in CHD + hypertension patients.Conclusion:Thrombosis possesses higher risk for CHD + hypertension patients, which is easier to cause acute cardiovascular events.Therefore, attention should be paid to coagulation function monitoring in order to prevent adverse cardiac events in these patients.
