Abstract：Objective To explore the significance of the relationship between detections of plasma catecholamine and 5-hydroxytryptamine and type A behavior in patientwith coronary heart disease（CHD）.Methods From January to December in 2015，60 CHD patients admitted into our hospitalwere selected as research objects.According to patients′behaviors，they were evenly divided into group type A group and type B group，which were corresponded with type A behavior of CHD and type B behavior of CHD.The level of renin-angiotensin-aldosterone system，the concentrations of 5-hydroxytryptamine，epinephrine，and norepinephrine were detected.Results At premise of the same cardiac function，the concentrations of 5-hydroxytryptamine，epinephrine，and norepinephrine in group A were greatly different from those in group B，which were displayed statistical differences（P＜0.05）.In type A group，the rate of ventricular premature beat was 33.33%，much higher than thatwas 6.67%of the type B group，which was displayed a statistical difference after intergroup comparison（P＜0.05）.There was difference in the level of renin-angiotensin-aldosterone system among patients with different cardiac functions（P＜0.05）.The higher the cardiac function was，the higher the level of renin-angiotensinaldosterone system became.Conclusion Detections of plasma catecholamine and 5-hydroxytryptamine can provide reliable and objective experimental basis for diagnosis and treatment of type A behavior of CHD.
