Effect of clearing heat and detoxification method on macrophages polarization in patients with acute myocardial infarction and heat toxin syndrome after intervention

Objective:To evaluate the effect of heat-clearing and detoxifying method on the macrophages polarization in patients with acute myocardial infarction with heat toxin syndrome after intervention.Methods:Sixty patients with acute myocardial infarction and undergoing percutaneous coronary intervention with heat toxin syndrome were randomly divided into a control group and a test group with 30 cases each.The control group was given conventional treatment,and the test group was given Huanglian Jiedu Decoction,the representative of the method of clearing heat and detoxification,orally on the basis of the control group.The intervention time of both groups was 2 weeks.Comparing The Seattle Angina Pectoris Scale(SAQ)before and after treatment,creatine kinase(CK),creatine kinase MB isoenzyme(CKMB),high-sensitivity troponin I(hs-TnI),and Lipoprotein-associated phospholipaseA2(LPPLA_2)),the phenotype ratio of M1 and M2 macrophages,and observe the adverse reactions.Results:After treatment,the SAQ scores of the two groups of patients were improved,and the levels of CK,CK-MB,hs-TnI,and LP-PLA_2 decreased significantly.The scores of AS,AF,TS,and DP in the SAQ of the test group were all higher than those of the control group,and the hs-TnI and LP-PLA_2 were better than those of the control Group(P<0.05 or P<0.01).After treatment,the proportion of M1 type macrophages in the two groups of patients'macrophages decreased significantly(P<0.05 or P<0.01),the ratio of M2 type macrophages increased(P<0.05),and the M1/M2 ratio decreased.The ratio of M1/M2 in the test group of the control group was significantly lower than that of the control group(P<0.01).There were no obvious adverse reactions in both groups.Conclusions:The method of clearing heat and detoxifying has a definite effect on patients with acute myocardial infarction of heat toxin syndrome after interventional operation.It can reduce myocardial damage,improve myocardial function,and reduce inflammation.And it is safe for clinical treatment without any increasing risk of bleeding or other risk of cardiovascular events.
