Active clinical trials for "Acute Coronary Syndrome"

Recent studies highlight the participation of gut microbes in the pathogenesis of both atherosclerotic heart disease and its adverse thrombotic events. Trimethylamine N-oxide (TMAO) is a plasma metabolite shown to be formed through a metaorganismal pathway involving nutrient precursors abundant in a Western diet and the sequential action of gut microbiota. Numerous studies reveal an association between systemic TMAO levels and cardiovascular risks in a variety of stable cohorts. The purpose of this study is to evaluate the efficacy of traditional Chinese Medicine formular (Compound pseudo-ginseng granules ) on the level of TMAO for the patient with acute coronary syndrome(ACS) undergoing percutaneous coronary intervention. 80 patients with ACS would be randomly allocated into interventional group(IG) and control group(CG). The patients in the IG would be administered by oral Compound pseudo-ginseng granules (twice per day ) for 90 days and those in the CG would receive the placebo twice per day during the same period. All of subjects would be administered with standard therapy in accordance with AHA/ACC guideline for ST-elevation myocardial infarction(STEMI) and Non ST-elevation myocardial infarction(NSTEMI).The primary endpoint is the plasma level of TMAO at 90-day follow-up. The second endpoint is the level of lipid, score of The Seattle Angina, fecal DNA extraction and pyrosequencing.

The study is an open-label, multicenter, and randomized study(five hospitals).The purpose of this study is to assess the differences in the effects of the evolocumab added to moderate-intensity statin therapy and the moderate-intensity statin only therapy on the regulation of LDL-C levels in patients with acute phase acute coronary syndrome after four weeks of treatment. The primary outcome is the percentage change in LDL-C in weeks 4 and week 12 after treatment. The secondary outcome is the occurrence of MACE after 12 weeks and 1 year of treatment.

The study objective is to assess the safety and efficacy of the Permanent Polymer Zotarolimus-Eluting Stent Resolute Integrity™ to the Polymer Free Amphilimus-Eluting Stent Cre8™ compared in an all-comer patient population. 1 month of dual antiplatelet duration will be applied in stable angina pectoris patients. Myocardial infarction patient population will be treated with 12 months of dual antiplatelet therapy.

Coronary heart disease (CHD) is one of the diseases characterised by biological aging as one of the important risk factors in several epidemiological studies. The mean telomere length and telomerase activity serve as markers for the biological age at the cellular level, with shorter telomeres and lower telomerase activity defining the increased biological age. Telomere length and telomerase activity, therefore, correlates with the risk of CHD and atherosclerosis. A present study states that the treatment with a statin is associated with a reduction in the number of clinical events but only in individuals with increased risk based on their telomere length. This suggests a positive relationship of telomere and telomerase system with the treatment with statins in CHD patients.

Ticagrelor is an oral, reversibly-binding, direct-acting P2Y12 receptor antagonist used clinically for the prevention of atherothrombotic events in patients with acute coronary syndromes (ACS). Guideline recommendations on the use of dual antiplatelet therapy (DAPT) have been formulated that ticagrelor 90 mg twice daily plus aspirin in preference to clopidogrel 75mg daily plus aspirin for patients who have an ACS with or without ST-segment elevation. These recommendations are primarily based on large, randomized, Phase III clinical trials. However, few East Asian patients (or those of East Asian descent) have been included in these trials to assess the use of these drugs. In addition, a growing body of data supported that East Asian might have different adverse event profiles (thrombophilia and bleeding) and "therapeutic window" compared with white subjects. Furthermore, "East Asian paradox" phenomenon has been described that East Asian patients have a higher prevalence of platelet reactivity during DAPT, but an ischaemic event rate following PCI or ACS is similar or even lower than white patients. Therefore, the antiplatelet treatment strategy that is most appropriate for East Asian patients is increasingly urgent. Therefore, we performed the current study to observe the different effects of low-dose ticagrelor (45 mg twice daily), conventional-dose ticagrelor (90 mg twice daily) and clopidogrel (75mg once daily) on high platelet reactivity (HPR) and IPA, and investigated the safety and efficacy of low-dose ticagrelor further in Chinese patients with non-ST-elevation ACS (NSTE-ACS).

A 4 week-duration cross-over study on Ticagrelor and Clopidogrel for the Acute Coronary Syndrome (ACS) and Chronic Kidney Disease (CKD) subjects, focusing on the platelet inhibition and safety observation.

The aim of this randomized, open-label clinical trial is to determine the impact of Sleep Study-Guided Multidisciplinary Therapy (SGMT, i.e. continuous positive airway pressure and behavioral therapy) for obstructive sleep apnea (OSA) in the sub-acute phase of acute coronary syndrome on cardiovascular outcomes. We hypothesize that SGMT will result in a lower (1) plasma NT-pro BNP, ST2 levels and hs-CRP, (2) 10-year risk of cardiovascular mortality based on the European SCORE algorithm, and (3) cardiovascular event rate, when compared with Standard Therapy. OSA is an emerging cardiac risk factor and prognostic marker. We have reported that OSA is a prevalent and independent predictor of adverse outcomes in patients with acute coronary syndrome. In this clinical trial, a continuation of my research and publication trajectory, 180 patients presenting with acute coronary syndrome will be randomly assigned to SGMT (n=90) or Standard Therapy (n=90) groups. Both groups will receive guideline-mandated treatment for acute coronary syndrome. Those assigned to SGMT will undergo a sleep study. Those found to have OSA will attend the SGMT clinic run by a multidisciplinary team. Advice on continuous positive airway pressure and behavioral therapy (weight loss, exercise, positional therapy, abstinence of alcohol and sleeping pills) will be given. The primary endpoint is plasma NT-pro BNP concentration at 6-month follow-up. The secondary endpoints are ST2, hs-CRP, 10-year risk of cardiovascular mortality based on the European SCORE algorithm which includes age, sex, smoking status, systolic blood pressure, and serum total cholesterol or total/HDL-cholesterol ratio. Adverse cardiovascular events at 3-year follow-up will be determined. In our aging population with an increasing prevalence of obesity, OSA will potentially become an increasingly important contributor to cardiovascular disease. Leveraging the collective expertise of a team of cardiologists and sleep physicians, our work will benefit society by advancing our understanding of the cardiovascular benefits of screening for and treating OSA.

To test the hypothesis that early (within 5-21 days after index event) administration of combined lipid-lowering therapy in extremely high risk population of patients with type 2 diabetes mellitus (T2DM) and hypertriglyceridemia (HTG) who experienced acute coronary syndrome (ACS) will be effective and well tolerated in achievement of contemporary strict requirements for triglyceride (TG) levels as an independent risk factor in the case of HTG with diabetes.

Compare with regular regimen, the aim of this study is to testify whether having more statin during PCI will benefit in Chinese population, and to find out optimal dose of the drug for patient after PCI.
