Active clinical trials for "Acute Coronary Syndrome"

The purpose of this study is to compare the efficacy and safety of ticagrelor with clopidogrel

The elderly represent a growing segment of the coronary population treated by dual antiplatelet therapy for percutaneous coronary intervention (PCI). These patients bear a higher risk of both ischemic events and bleeding complications than younger patients, with a subsequently higher rate of mortality.Recentprogress in antithrombotic treatment demonstrated the efficacy of adding a P2Y12 receptor antagonist to low-dose aspirin. Whether this benefit is also present in the elderly remains a debated issue due to the lack of specific data in this sub-population. The present study was realized to provide specific data on platelet response to clopidogrel, standard dose (75 mg) or prasugrel 5 mg in elderly patients (≥75 years old) whereas the superiority in PR response of the latter should allows the Prasugrel therapy in elderly patients with the better clinical efficacy and therapeutical safety already showed compared with Clopidogrel.

In the POPular CABG study we investigate if the addition of ticagrelor, a drug that inhibits blood platelets from clotting, to treatment with aspirin will reduce the rate of saphenous vein graft occlusion as assessed with coronary computed tomography angiography at 1 year after coronary artery bypass grafting surgery.

To evaluate The Safety and Efficacy of 'AVI' Stent Comparing with Firebird2® For Treating Coronary Revascularization.

Objective : To test the safety of 6 month-duration of dual antiplatelet therapy (DAPT) compared to conventional 12-month-or-longer duration after second-generation drug-eluting stent (DES) implantation in patients with acute coronary syndrome (ACS). Hypothesis : A 6-month duration of DAPT is non-inferior to a conventional 12-month-or longer duration of DAPT at preventing the occurrence of major adverse cardiac and cerebrovascular events (MACCE) at 18-month after second-generation DES implantation in patients with ACS.

Among the patients with coronary heart disease, those with ACS (acute coronary syndrome) are extremely high-risk patients. Therefore, management outside hospital, especially the regular administration of drugs, is vital to prevent the recurrence of cardiovascular events. However, most patients often fail to stay on a long-term administration regimen, especially the administration of statins. According to the statistics, the average duration adhered with statin in patients with ACS is less than 3 months, use of statin at hospital discharge was only 80% and 65% in 6 month, with a very low LDL-C control rate (about 11% at 6 months), which poses a threat to the recurrence rate of cardiovascular events in patients with ACS. It was found in previous studies that there were many factors influencing patients' compliance, in which patients' refusing to take medicine accounted for a higher proportion. It suggests that patient had not recognized the importance of long-term administration. Therefore, it is extremely important for physicians to strengthen patient education and regular follow-up visits during disease management. Moreover, the effectiveness of patient education during chronic disease management has already been proved in some studies abroad, and the interventional effect of multiple patient education process outweighs that of single approach education. Thus, we intend to conduct a randomized and controlled study to explore the effect of multi-channel intensive patient education on LDL-C target achieving rate and statin adherence in patients with ACS in China.

A double blind, randomized, placebo-controlled study will be conducted in cardiac ICU patients who had been diagnosed with acute coronary syndrome, using a sleep promoting drug (zolpidem controlled release). The study hypothesis is that sleeping better can improve the heart recovery in patients with a diagnosis of acute coronary syndrome.

Ischemic heart disease is the leading cause of death and disability in developed countries and is responsible for a third of deaths in persons over 35 years . The most severe form of ischemic heart disease is sudden death and acute coronary syndrome (ACS). There is evidence that early and optimal treatment of ACS decreases mortality. Within the optimal treatment, these patients must receive a reperfusion therapy as mechanical or pharmacologic treatment. In addition to reperfusion treatment, antiplatelet therapy is a central part of the management. Aspirin plus a P2Y12 inhibitor have been shown to decrease mortality. In our country, clopidogrel is the more accessible and used P2Y12 inhibitor; however, it has been shown to have a wide variability in response and this variability could be influenced by different pharmacological, genetic and environmental factors. Platelet reactivity measured by aggregometry predicts major cardiovascular events in ACS patients treated with clopidogrel. Due to their frequent prescription, generic clopidogrel efficacy must be evaluated. The purpose of this study is to compare the platelet reactivity in patients with ACS receiving clopidogrel generic versus patent.

This study is to test the feasibility and tolerability of the metoprolol optimal dosing pathway by observing the percentage of patients achieving target dose followed the pathway on ACS patients during hospitalization.
