Methods： Block randomization was performed to randomly allocate 750 patients into KA （376 cases） and control groups （374 cases）. During an angina attack, the KA group received 3 consecutive sublingual sprays of KA （0.6 mL per spray）. The control group received 1 sublingual nitroglycerin tablet （NT, 0.5 rag/tablet）. Log-rank tests and Kaplan-Meier estimations were used to estimate the angina remission rates at 6 time-points after treatment （1,2, 3, 4, 5, and 〉5 min）. Logistic regression analysis was performed to observe the factors influencing the rate of effective angina remission, and the remission rates and incidences of adverse reactions were compared for different Canadian Cardiovascular Society （CCS） classes of angina. Results： The 5-min remission rates in the KA and control groups were not significantly different （94.41% vs. 90.64%, P〉0.05）. The angina CCS class significantly influenced the rate of remission （95% confidence interval = 0.483-0.740, P〈0.01）. In the CCS subgroup analysis, the 3- and 5-min remission rates for KA and NT were similar in the CCS I and IV subgroups （P〉0.05）, while they were significantly better for KA in the CCS Ⅱ and Ⅲ subgroups （P〈0.05 or P〈0.01）. Furthermore, the inciden0ce of adverse reactions was significantly lower in the KA group than in the control group for the CCS Ⅱ and Ⅲ subgroups （9.29% vs. 26.22%, 10.13% vs. 20.88%, P〈0.05 or P〈0.01）. Conclusions： KA is not inferior to NT in the remission of angina. Furthermore, in CCS Ⅱ and Ⅲ patients, KA is superior to NT, with a lower incidence of adverse reactions. （Registration No. ChiCTR- IPR-15007204）展开更多

It is of potential significance to explore the blood indexes predicting plaque characteristics. We investigated the relationship among soluble CD105, hypersensitive C-reactive protein （hs-CRP）, and coronary plaque morphology.Methods A clinical study from April 2004 to December 2006 was conducted in 130 patients who were divided into 3 groups： 56 patients （43.1%） in stable angina （SA） group, 52 patients （40.0%） in unstable angina （UA） group and 22 patients （16.9%） in acute myocardial infarction group. The concentrations of soluble CD105 and hs-CRP were measured in all of the patients by cardioangiography （CAG）. Plasma samples of arterial blood were collected prior to the procedure. The levels of soluble CD105 and hs-CRP were measured by enzyme-linked immunosorbent assay （ELISA）.Results Unstable and ruptured plaque was found more frequently in patients with acute myocardial infarction and UA. External elastic membrane cross-sectional area （EEM CSA）, plaque area, lipid pool area and plaque burden were significantly larger in the ruptured and unstable plaque group. Positive remodeling, thinner fabric-cap, smaller minimal lumen cross-sectional area （MLA）, dissection and thrombus were significantly more frequent in the ruptured and unstable plaque group. Remodeling index （RI） was positively correlated with the levels of soluble CD105 in the UA group （r=0.628, P〈0.01） and the acute myocardial infarction group （r=0.639, P〈0.01）. The levels of soluble CD105 and hs-CRP were higher in the ruptured plaque group. Soluble CD105 〉4.3 ng/ml was used to predict ruptured plaque with a receiver operating characteristic （ROC） curve area of 0.77 （95% confidence interval （CI）, 66.8%-87.2%）, a sensitivity of 72.8%, a specificity of 78.0% and an accuracy of 70.2% （P〈0.01）, similarly for hs-CRP 〉 5.0 mg/ml with a ROC curve area of 0.70 （95% CI, 59.2%-80.2%）, a sensitivity of 70.2%, a specificity of 76.2% and an accuracy of 67.2% （P〈0.01）.Conclusions The plaque characteristics correlate with the clinical presentation. The elevation of soluble CD105 and hs-CRP is related to the plaque instability and rupture.展开更多

Methods: A total of 1,087 hospitalized patients with CAD from four hospitals in Beijing, China were consecutively selected between August 2011 and February 2012. The patients were assigned to two groups based on the treatment: Chinese medicine(CM) plus conventional treatment, i.e., IM therapy(IM group); or conventional treatment alone(CT group). The endpoint was major adverse cardiac events [MACE; including cardiac death, myocardial infarction(MI), and revascularization]. Results: A total of 1,040 patients finished the 2-year follow-up. Of them, 49.4%(514/1,040) received IM therapy. During the 2-year follow-up, the total incidence of MACE was 11.3%. Most of the events involved revascularization(9.3%). Cardiac death/MI occurred in 3.0% of cases. For revascularization, logistic stepwise regression analysis revealed that age 65 years [odds ratio(OR), 2.224], MI(OR, 2.561), diabetes mellitus(OR, 1.650), multi-vessel lesions(OR, 2.554), baseline high sensitivity C-reactive protein level 3 mg/L(OR, 1.678), and moderate or severe anxiety/depression(OR, 1.849) were negative predictors(P<0.05); while anti-platelet agents(OR, 0.422), β-blockers(OR, 0.626), statins(OR, 0.318), and IM therapy(OR, 0.583) were protective predictors(P<0.05). For cardiac death/MI, age 65 years(OR, 6.389) and heart failure(OR, 7.969) were negative predictors(P<0.05), while statin use(OR, 0.323) was a protective predictor(P<0.05) and IM therapy showed a beneficial tendency(OR, 0.587), although the difference was not statistically significant(P=0.218). Conclusion: In a real-world setting, for patients with CAD, IM therapy was associated with a decreased incidence of revascularization and showed a potential benefit in reducing the incidence of cardiac death or MI.展开更多

Moreover, the effects of atorvastatin and probucol on PcyC and the severity of coronary lesions are unknown. This study was to evaluate the effects of the combination of atorvastatin and probucol on PcyC and severity of coronary lesion in patients with borderline coronary lesions. Methods One hundred and thirty consecutive patients with borderline coronary lesions （40% to 60% isolated single stenosis assessed by quantitative coronary angiography） were enrolled into the borderline coronary lesion （BCL） group, and one hundred and thirty-six subjects without coronary lesions comprised the controls （CTR）. The subjects in the BCL group were randomized into routine treatment （RTT, n=60）, and combined treatment with atorvastatin 20 mg plus probucol 1.0 g daily added to routine medication （CBT, n=70）, both groups were treated for 6 months continuously. The levels of PcyC, high-sensitive C-reactive protein （hs-CRP）, total cholesterol （TC）, low-density lipoprotein cholesterol （LDL-C）, high-density lipoprotein cholesterol （HDL-C）, and triglycerides （TG） were determined. One hundred and four subjects in the BCL group were rechecked by coronary angiography. Results PcyC levels were significantly higher in the BCL group than in the CTR group; （2003.26＋825.73） ng/ml vs. （1897.83＋664.46） ng/ml （P 〈0.01）. Compared with patients in the RTT group, the levels of PcyC, TC, LDL-C, TG and hs-CRP were significantly lower in the CBT group （P 〈0.05）. Moreover, there was a trend towards a slight decrease in the RTT patients, （54.38＋10.67）% vs. （50.29＋9.89）% （P 〉0.05）, and a significant decrease in the CBT patients, （53.65＋9.48%） vs. （40.38＋12.93）% （P 〈0.05）, in the mean percent stenosis of borderline coronary lesions before and after six months of treatment. Conclusions Cystatin C played an important role in with the severity of coronary lesions. The combination the treatment of choice. the development of coronary artery disease, and was associated of atorvastatin and probucol decreased PcyC levels, and could be展开更多
