OBJECTIVETo investigate the therapeutic effects of propyl gallate (PrG) in combination with standard medication on patients with non-ST-elevation acute coronary syndrome (NST-ACS), including unstable angina and acute non-ST-elevation myocardial infarction, and its influences on serum inflammatory marker and platelet activation.

METHODSFifty-five patients with NST-ACS were randomly assigned to two groups. Accessory to the standard Western medicine, the 27 patients in the tested group treated with PrG and the 28 in the control group with salvia composite (SC), all being medicated for 14 days. Effects on angina pectoris and electrocardiogram were observed. The positive rate and mean fluorescence density (MFI) of GP IIb-IIIa and CD62p expression on platelet surface were detected using flow cytometer; the serum concentration of high sensitive C-reactive protein (Hs-CRP) was determined using ELISA before and after treatment respectively.

RESULTSThe therapeutic effects on angina and electrocardiogram between the two groups showed no significant difference. Serum level of Hs-CRP, GP IIb-IIIa MFI and CD62p positive rate were significantly lowered after treatment in both groups (P < 0.05), no significant difference was found between groups, though the lowering of Hs-CRP and GP IIb-IIIa MFI in the tested group displayed a further decreasing trend.

CONCLUSIONIn combination with standard medication of Western medicine, PrG and SC showed no obvious difference in the therapeutic effect and influences on angina pectoris and electrocardiogram in patients with non-ST-elevation acute coronary syndrome.
