OBJECTIVE: To determine the effect of Tongxinluo on the endothelial function and hypersensitive C-reactive protein (hs-CRP) in acute coronary syndrome patients undergoing percutaneous coronary intervention(PCI). METHODS: Thirty-three patients with unstable angina pectoris and 6 patients with acute myocardial infarction who underwent PCI for stenotic lesions of the coronary artery were enrolled. The patients were randomly assigned to a conventional group (n = 19) which took routine treatment or a tongxinluo group (n = 20) which took Tongxinluo(4 capsules once, 3 times per day) at the base of routine treatment after PCI. Nitric oxide synthase (NOS), nitric oxide (NO), endothelium-dependent vasodilation which was evaluated in the brachial artery flow mediated diameter(FMD) and hs-CRP were measured before the PCI and 24 hours and 3 months after the PCI. The correlation between NO and hs-CRP was analyzed. RESULTS: NOS, NO, and FMD in the 2 groups 24 hours after the PCI were significantly lower than those before the PCI(P < 0.05), but hs- CRP obviously increased (P < 0.05). NOS, NO, and FMD 3 months after the PCI in the 2 groups were significantly higher than those before the PCI (P < 0.05 or P < 0.01), but hs-CRP obviously decreased (P < 0.01).All indexes mentioned above in the Tongxinluo group showed greater changes than those of the conventional group(P < 0.05). NO was negatively correlated with hs-CRP (r = -0.3219, P<0.01). CONCLUSION Tongxinluo capsules have obvious beneficial effect on endothelial function and anti-inflammation in acute coronary syndrome patients undergoing PCI, by directly acting on the endothelium and indirectly inhibiting inflammation.

OBJECTIVE: To determine the relation between plasma tissue factor (TF) and serum angiotensin II(AngII) and the effect of different dosages of fosinopril on chronic heart failure(CHF). METHODS: Thirty healthy controls and 35 CHF patients were recruited to observe AngII,TF, left ventricular ejection fractions(LVEF) and left ventricular end-systolic volume index (LVESVI) at baseline and 10 weeks after the treatment. The 35 patients were randomly assigned into 2 groups: A routine dosage fosinopril group received 10 mg once daily and a middle dosage group received 10 mg twice a day for 10 weeks. RESULTS: Compared with the healthy controls, AngII,TF,and LVESVI significantly increased (P<0.01) and LVEF significantly decreased (P<0.01) in CHF patients. The TF was positively correlated with AngII(r=0.2491, P<0.01) in the patients. After the 10-week treatment with different dosages of fosinopril, AngII,TF,and LVESVI obviously decreased(P<0.05 or P<0.01) and LVEF significantly increased in the 2 groups (P<0.05 or P<0.01). The middle dosage group changed more than the routine dosage group (P<0.01). CONCLUSION TF is positively correlated with AngII in CHF patients. Fosinopril can greatly improve cardiac function and antagonize prethrobotic state,and the therapeutic effect improves with the dosage increase.
