Active clinical trials for "Coronary Disease"

The purpose of this study is to compare the effects of pravastatin and rosuvastatin on coronary plaque characteristics in patients with stable angina pectoris.

The purpose of this study is to measure the effect of ranolazine on ETT (exercise treadmill test) exercise duration in four ethnic subgroups with established coronary artery disease and risk factor(s) for the metabolic syndrome: Caucasian, African American, Southeast Asian and East Indian.

In hemodialysed patients, coronary heart disease is the leading cause of mortality and morbidity. Most of the commonly used drug for ischemia are used in this patients, but few prospective data are available. Among anti-ischemic drugs betablocker provided evidence of beneficial effects on outcome and, in dialysis patients, carvedilol was successfully used also in heart failure. Ivabradine is the latest anti-ischemic drug that provided evidence of benefit in general population, but no study is available in dialysis patients. Aim of the present study is to compare in a randomized, double-blind, parallel group trial the effects of ivabradine compared with carvedilol on event-free survival at 18 months in a hemodialysed population of patients with established coronary heart disease.

Clopidogrel low response is associated with a significantly higher risk for ischemic complications after percutaneous coronary intervention. Ticagrelor and prasugrel are more potent platelet inhibitory drugs and both have been shown to significantly reduce ischemic events as compared to clopidogrel. No direct comparison between ticagrelor and prasugrel in terms of their antiplatelet efficacy exists. The aim of this study is to assess the antiplatelet treatment efficacy of ticagrelor versus prasugrel over time in confirmed clopidogrel low responders undergoing percutaneous coronary intervention.

The SYNTAX trial is designed to determine the best treatment for patients with complex coronary disease (blocked or narrowed arteries in both the right and left sides of the heart) by randomizing patients to receive either percutaneous coronary intervention (PCI) with polymer-based paclitaxel-eluting TAXUS stents or to coronary artery bypass surgery (CABG).

In this study, simvastatin combined with Ezeimebum was used to enhance lipid reduction, and IVUS was used to evaluate the volume and composition of coronary plaque before and after treatment. The aim is to evaluate the overall intervention effect of Ezeimebum on stable angina pectoris with diabetes mellitus on the basis of statins.

This study evaluates coronary artery disease after heart transplantation and its relation to platelet function. Furthermore, we will evaluate extracorporeal photopheresis as treatment of coronary artery disease after heart transplantation.

This is a single-center, randomized, single-blind, investigator-initiated, pharmacological study with a parallel design. Patients with non-ACS undergoing primary percutaneous coronary intervention will be randomized after informed consent, in a 1:1:1:1 ratio to the following treatment groups: Group Α: Domestic Clopidogrel 300mg as a loading dose before PCI, followed by 75mg per day. Group B: Domestic Clopidogrel 600mg as a loading dose before PCI, followed by 75mg per day. Group B: Imported Clopidogrel 300mg as a loading dose before PCI, followed by 75mg per day. Group D: Imported Clopidogrel 600mg as a loading dose before PCI, followed by 75mg per day. Platelet inhibition ratio assessment by thrombelastogram will be performed，2 hours after the loading dose(Day 0)， 6 hours after thrombelastogram (Day 0), 30 day after thrombelastogram. Documentation of major adverse cardiac events (death, myocardial infarction, stroke, revascularization procedure with PCI or CABG) and serious adverse events (bleeding, other adverse events)will be performed until Day 30.

The purpose of this study is to determine whether Shexiang Baoxin Pill is effective in the treatment of coronary artery disease not amenable to revascularization on the basis of western medicine therapy.

The primary of this registry is to evaluate whether the availability of CTA/CT-FFR procedure could effectively optimize the flow of clinical practice of stable chest pain versus conventional clinical pathway in decision making, avoid the overuse of invasive procedure, finally improve clinical prognosis and reduce total medical expenditure. This registry is randomized, open labeled, prospective designed and will be performed in 6 Chinese hospitals. Approximately 1200 subjects will be enrolled and subsequently assigned to either routine clinically-indicated diagnostic care group (CID arm) or CTA/CT-FFR care group (CTA/CT-FFR arm) via computer-generated random numbers (1:1 ratio)
