Objective

2

To discuss the clinical efficacy of Xintong oral liquid on heart failure with syndrome of Qi deficiency， phlegm and blood stasis caused by acute myocardial infarction （AMI） and the effect on inflammatory factors.

Method

2

One hundred patients were randomly divided into observation group （50 cases） and control group （50 cases） by random number table. Both groups got comprehensive treatment of western medicine. Patients in control group got simulated medicine of Xintong oral liquid， 20 mL/time， 3 times/day. Patients in observation group got Xintong oral liquid， 20 mL/time， 3 times/day. The treatment lasted for 4 weeks. Before the treatment， and at the second week and forth week after treatment， levels of cardiac troponin I （cTnI）， cardiac troponin T （cTnT）， heart type fatty acid binding protein （H-FABP）， left ventricular ejection fraction （LVEF）， cardiac output （CO）， cardiac output per stroke （SV） and left ventricular end diastolic diameter （LVEDd）， N-terminal B-type natriuretic peptide （NT-proBNP）， lipoprotein phospholipase A

（Lp-PLA

）， high sensitive C-reactive protein （hs-CRP）， interleukin-6 （IL-6） and tumor necrosis factor-

（TNF-

α

） were detected. The 6-minute walking test was performed to record the 6-minute walking distance and the ratio of 6 min walking distance to estimated value. Scores of traditional Chinese medicine （TCM） syndromes， minnesota Heart Failure quality of life questionnaire （MLHFQ） and Killip classification of cardiac function were recorded. During the 2 months' follow-up， adverse cardiovascular events （MACE） were recorded， and the safety was evaluated.

Conclusion

2

Based on the comprehensive treatment of Western medicine， Xintong oral liquid can reduce the degree of myocardial injury， protect myocardium， improve cardiac function， reduce inflammatory reaction， reduce the occurrence of mace， effectively control clinical symptoms， and improve exercise tolerance and quality of life.
