Active clinical trials for "Myocardial Ischemia"

In this randomized clinical trial before and after study we will assess the effect of L-citrulline malate on brachial index in patients with coronary heart disease based on their smoking history. Twenty patients with coronary heart disease with no history of diabetes or other chronic diseases and with no history of myocardial infarction in the last 6 months will participate in our trial.A written well-versed permission was attained from all patients. We will measure the brachial index tow times once before giving L-Citrulline malate and the other time after 2 weeks giving it.Patients receiving L-Citrulline malate as a 1 gram dry powder agent twice a day, that should in use with 250 mg dilute water .The patients will followed after 2 weeks by measuring brachial index which is our primary outcome measurement in this trial.We assumed that the brachial index in both smoker and non-smoker group of patients with coronary heart disease would change to normal or close to normal after giving 1 gram L-citrulline malate twice a day for 2 weeks.

The objective of this research is to assess the clinical results of implantation of different drug eluting stents under "aggressive" intravascular ultrasound (IVUS) guided all the way up to 24 months after operation and to establish the significance of the data of an optical coherent tomography (OCT) for the assessment of direct results of stenting and the degrees of endothelization of stent after 6 months. The following hypothesis formed the base for this study: IVUS guided intervention allows to improve the results and increase the safety of implantation drug eluting stents. Suboptimal results according to IVUS data can influence the follow up results of treatment. Suboptimal results according to OCT data, which are not revealed by IVUS, can influence the follow up results of treatment. The use of strategy of stenting with the achievement of optimal results under the intravascular methods of visualization allows to reduce the time of application of antiplatelet therapy. The modern limus-eluting stents do not differ in the follow up results in investigated criteria.

Title: A randomized, double-blind, multi-centered, placebo-controlled trial to examine effects of of Heart-protecting Musk Pill on clinical outcomes in patients with chronic stable coronary artery disease Objective: To examine effects of of Heart-protecting Musk Pill, a traditional Chinese medicine, on clinical outcomes in patients with chronic stable coronary artery disease The study hypothesis: The null hypothesis: the combined incidence of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke in the treatment group is the same as that in control group. The alternative hypothesis: the combined incidence of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke in the treatment group is different from that in control group. Sample size: 2700 patients will be randomized, 1350 in treatment group and 1350 in placebo group. Number of sites: 99 sites in China Study drugs: Heart-protecting Musk Pill and the matching placebo pills. Design: A randomized, double-blind, multi-centered, placebo-controlled trial. Patients will be randomized to treatment group and placebo group after screening and get corresponding treatment as follow. Treatment group: Standard treatment for coronary artery disease plus 2 Heart-protecting Musk Pills each time, three times a day by mouth for 24 months. Control group: Standard treatment for coronary artery disease plus 2 placebo pills each time, three times a day by mouth for 24 months. Patients will be followed up at baseline, 1, 3, 6, 9, 12, 18, 24 months after randomization. During follow-up period, patients could undertake PCI or CABG if angina get out of control or evidence of ischemia aggravated is found.

The purpose of this study is to demonstrate that a BioFreedom™ Drug Coated Stent is non-inferior to a bare metal stent at one year as measured by the composite safety endpoint of cardiovascular death, myocardial infarction and definite/probable stent thrombosis, and that its efficacy is superior to a bare metal stent as measured by clinically driven TLR at one year.

The study will evaluate the use of Flurpiridaz F18 injection in patients with CAD to determine if the study drug in PET imaging is better than SPECT imaging currently used for this purpose.

To study whether renal sympathetic denervation(RSD) will reduce the all-cause mortality and the recurrence rate of a composite of cardiovascular event(including angina, myocardial infarction, repeat percutaneous coronary intervention and coronary artery bypass grafting) in patients after percutaneous coronary intervention(PCI). Besides whether RSD can reduce the risk factors for coronary heart disease.

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.

This study aims to test the hypothesis that jailed-balloon technique(JBT) is superior to jailed-wire technique(JWT) in non-left main coronary bifurcation percutaneous coronary intervention(PCI) by lowering the risk of side branch(SB) loss and PCI related myocardial infarction, as well as 1-year major adverse cardiovascular events(MACEs).

The objective of the study is to assess the superiority of the everolimus-eluting stent (Endeavor Resolute®) compared with the everolimus-eluting stent (XIENCE V®) regarding uncovered stent strut segments.
