ABSTRACT
Objective: To study the impact of ticagrelor on inlfammatory factors in patients with unstable angina pectoris (UAP) after percutaneous coronary intervention (PCI). Methods: Based on conventional medication, a total of 100 UAP patients after PCI were randomly divided into 2 groups for anti-platelet therapy:Treatment group, the patients received aspirin+ticagrelor and Control group, the patients received aspirin+clopidogrel. n=50 in each group, all patients were treated for 12 months. Plasma levels of inlfammatory factors were examined before treatment and 24h, 7d, 28d after the operation. The patients were followed-up for 12 months for ischemic events, bleeding events and adverse drug reactions. Results: Before treatment, plasma levels of IL-6, IL-18, TNF-α, PDGF were similar between 2 groups (t=0.1356, 0.1668, 0.2473, 0.5780, all P>0.05). At 24h post-operation, the above inlfammatory factors were signiifcantly increased by peaks in both groups and decreased thereafter. At 24h, 7d and 28d post-operation, the levels of IL-6, IL-18, TNF-a, PDGF in Treatment group were all lower than Control group at each corresponding time point (at 24 post-operation, t=2.0856, 2.4399, 2.2217, 2.2053, all P0.05). Conclusion: Compared to clopidogrel, ticagrelor could better decrease plasma levels of inlfammatory factors, it may reduce ischemic events without elevate bleeding events.
ABSTRACT
Objective To compare the effect of atorvastatin and rosuvastatin on myocardial injure and inflammatory factors in patients with unstable angina pectoris(UAP)undergoing percutaneous coronary intervention(PCI).Methods Ninety six UAP pa-tients undergoing PCI were enrolled in the study and divided into two groups,patients were given atorvastatin(20 mg/d)or rosuv-astatin(20 mg/d)besides conventional treatment for 1 week before PCI.Datas were collected before medication,PCI and Twenty-four hours after PCI,including CK-MB,cTnI,hs-CRP,TNF-α,IL-6 and IL-10.Results Twenty-four hours after surgery,the PCI, CK-MB,cTnI,hs-CRP,TNF-α,IL-6 of rosuvastatin group were lower than those of atorvastatin group(P <0.05),but IL-10 of ro-suvastatin group was higher than that of atorvastatin group(P <0.05).Conclusion Rosuvastatin (20 mg/d)is better than atorvas-tatin (20 mg/d)in the efficacy of UAP patients undergoing PCI,which can reduce the level of myocardial injure and inflammatory factors effectively.
ABSTRACT
Objective To explore the effect of atorvastatin on high-sensitivity C-reactive protein (hs-CRP) and interleukin-6 (IL-6) in unstable angina pectoris (UAP) patients after intervention.Methods Eighty cases with UAP who underwent percutaneous coronary intervention (PCI) were divided into group A and group B by random digits table method with 40 cases each after PCI.The patients in group A were given regular heart treatment and atorvastatin 20 mg treatment.The patients in group B were given regular heart treatment and atorvastatin 40 mg treatment.The serum hs-CRP and IL-6 was determined before treatment and 24 h,3 weeks after treatment and compared between two groups.Results There was no significant difference in the serum hs-CRP and IL-6 before treatment between group A and group B [(5.6 ± 1.2) mg/L vs.(5.6 ± 1.1) mg/L and (211.9 ± 21.2) ng/L vs.(209.6 ± 19.9) ng/L,P ＞ 0.05].The serum hs-CRP and IL-6 24 h after treatment in group A and group B were increased compared with that before treatment,and there was significant difference(P ＜ 0.05),but there was no significant difference between group A and group B[(8.1 ± 1.1) mg/L vs.(8.5 ± 1.2) mg/L and (311.1 ± 20.9) ng/L vs.(313.3 ± 18.5) ng/L,P＞ 0.05].The serum hs-CRP and IL-6 3 weeks after treatment in group A and group B were decreased compared with that before treatment,there were significant difference (P ＜ 0.05),and there were significant difference between group A and group B [(3.1 ± 1.1) mg/L vs.(1.9 ±0.8) mg/L and (163.3± 18.5) ng/L vs.(123.3± 19.5)ng/L,P ＜ 0.05].No obvious adverse reaction was observed in two groups after treatment and liver function was not seen obvious anomaly.Conclusions Atorvastatin treatment in UAP patients after PCI can significantly reduce the serum hs-CRP and IL-6,and the 40 mg treatment is better than the 20 mg treatment.It is worth of clinical application.
ABSTRACT
Objective: To investigate effect of curcumin on serum gelatinases levels in patients with unstable angina pectoris（UAP）. Methods： A total of 80 UAP patients admitted from January 2010 to September 2010 were enrolled and randomly divided into curcumin treatment group (n=40) and routine treatment control group (n=40). Serum levels of gelatinases [contain matrix metalloproteinase（MMP）-2 and -9) of the two groups were measured before and 30d after treatment. Results：Compared with before treatment , after treatment, serum gelatinases levels significantly decreased [MMP-2：（52.64±6.77）ng/ml vs. （32.65±1.67）ng/ml，MMP-9：（56.75±7.34）ng/ml vs.（35±1.88）ng/ml ] (P<0.01) in curcumin treatment group (P<0.01), and they were significantly lower than those of routine treatment control group [MMP-2：（32.65±1.67）ng/ml vs.（37.78±2.76）ng/ml，MMP-9：（35±1.88）ng/ml vs.（40.23±1.95）ng/ml ] , P<0.05 all. Conclusion：Curcumin could decrease serum levels of gelatinases in patients with unstable angina pectoris, and possesses effect of stabilization coronary artery plaque.
ABSTRACT
Objective To observe the therapeutic effect of low molecular weight heparin calcium (LMWHC) in treating unstable angina pectoris.Methods 78 hospitalized patients of unstable angina pectoris were randomly divided into two groups:32 as control group who were treated with routine method,and 46 as treatment group who were treated with routine method plus LMWHC.Results The clinical therapeutic effect in the treatment group was 91.3%,which compared with the control group (62.5%) was obviously of great significance (P
ABSTRACT
Objective To observe the treatment effect of low molecular weight heparin (LMWH) in the treatment of unstable angina pectoris.Methods LMWH (0.4～0.6 ml Bid) was used through subcutaneous injection in 36 cases of unstable angina pectoris for 14 days on end.Results The clinical effective rate was 66.67%.The drug was effective in the decreasing of the frequency and time of angina pectoris,and also in the decreasing of nitroglycerin consumption as well as in the improvement of the scope and severity of cardiac ischemia by ECG.Conclusion LMWH is an effective and safe drug for the treatment of unstable angina pectoris.
ABSTRACT
The 34 cases in the treatment group were treated with allicin injection through Murphy drip for a course of 10 days with nitroglycerin group as control. Results demonstrated that the total effective rate for symptoms and ECG were 82% and 62% respectively for the treatment group. It also markedly lowered the level of plasmal endothelin, and that of blood sugar in diabetics'. Adverst effects included local pain at the injection site and headache, the incidence of which were 18% and 6% respectively. This therapy is a satisfactory one for stubborn angina pectors.
ABSTRACT
This therapy, with a total effective rate of 90%, was satisfactory for all syndromes and various kinds of UA. Those cases with plasmal NO and t -PA lower than normal recovered to certain extent after the treatment. But there was no effect on plasmal ET after treatment, indicating that the mechanism of Shen - yuan - dan may be partially due to the repair of vessel endothelium, lowering of vessel tension, decrease of unstable thrombus through the regulation of plasma NO, t -PA level, hence, the improvement of coronary blood supply.
