Active clinical trials for "Coronary Artery Disease"

Rotational atherectomy is an established tool to treat blocked arteries in the heart, in which the blockage is due to significant amounts of calcified material. In rotational atherectomy, a rotating instrument is used to break up the calcification before a stent is placed and helps restore blood flow to the heart. However, severely calcified regions are difficult to treat and even after treatment arteries can re-clog and major cardiac events occur. This study will test if rotational artherectomy with the addition of a cutting balloon - a balloon with microsurgical blades on its outer surface which make longitudinal incisions in the calcified area in order to open resistant clogs - will result in increased blood vessel lumen, more optimal stent expansion and decreased cardiac problems compared to current standard treatment.

The purpose is to compare median two-year clinical outcome after OCT guided vs. standard guided revascularization of patients requiring complex bifurcation stent implantation

To compare coronary healing after optical coherence tomography guided versus conventionally angiography guided percutaneous coronary intervention with the Magmaris bioresorbable scaffold.

To assess whether vulnerable coronary plaques have more uptake of 68Ga-Dotatate than non-vulnerable plaques.

The study aims to compare a preventive percutaneous coronary intervention (PCI) plus optimal medical treatment (OMT) strategy vs. OMT for treatment of non-functionally significant non-culprit lesions presenting with optical coherence tomography (OCT) findings indicative of vulnerable plaque, in patients with ST-elevation myocardial infarction (STEMI) and multivessel disease.

This clinical trial develops and tests a culturally-appropriate educational program (Indigenous SIPin) for reducing sugar-sweetened beverage consumption in men affiliated with Native American athletics communities. Sugary drinks are drinks like pop, soda, and juice. Increased sugar consumption may lead to an increased risk of chronic diseases, including obesity, diabetes, some types of obesity-related cancers, coronary heart disease, hypertension, and dental decay. A culturally sensitive program may help reduce sugar-sweetened beverage consumption in Native American men

Coronary artery disease (CAD) is a manifestation of systemic atherosclerosis for which single antiplatelet therapy (SAPT) is indicated if patients are stable. Recently dual pathway inhibition (DPI) by combining a low-dose factor Xa inhibitor (rivaroxaban2.5mg twice daily) with a single platelet inhibitor (ASA) has been demonstrated to be beneficial in treating CAD. The exact mechanisms underlying the benefits of DPI, are not completely understood. CAD is characterised by a state of chronic low-grade inflammation, where monocytes from CAD patients have a higher immune responsiveness to ex vivo stimulation with lipopolysaccharide (LPS) compared to healthy matched controls. Surprisingly, the investigators have recently observed an elevation in ex vivo immune responsiveness to LPS stimulation when switching from ASA monotherapy to DPI of ASA combined with rivaroxaban inpatients with peripheral arterial disease (n=11; unpublished). Remarkably this was associated with no changes in systemic inflammation, as determined by Olink proteomics analysis. These findings suggest that factor Xa inhibitors can enhance immune cell responsiveness despite being clinically beneficial to CAD. The exact mechanisms contributing to the observed increased immune responsiveness remain unexplored.

PIONEER-II OPC trial is a prospective, multicenter, single-arm registry trial. 1000 subjects from approximately 40 interventional cardiology centers will be enrolled to evaluate the target lesion failure(TLF) as the primary endpoint at 1 year. And all the subjects will be followed up to 5 years to attain the data of the secondary endpoints.

The purpose of this study is to compare early vessel healing after implantation of SYNERGY drug eluting stent (DES) or BioMatrix NeoFlex DES at one and three months in two cohorts.

The aim of this study is to evaluate if acute invasive coronary evaluation and treatment conducted within 12 hours of diagnosis improves clinical outcome compared to a deferred, subacute strategy in patients with unstable angina pectoris (UAP) / non-ST segment elevation myocardial infarction (NSTEMI) Acute coronary syndrome (ACS) Furthermore, in an observational design the potential clinical benefit of coronary computed tomography angiography (CCTA) to select patients for invasive investigation and treatment in the two treatment arms (acute vs deferred) is evaluated. The following main hypothesis will be tested: Very early invasive coronary investigation improves clinical outcome in patients with UAP/NSTEMI-ACS CCTA performed before invasive coronary investigation will improve clinical management of patients with UAP/NSTEMI-ACS
