Active clinical trials for "Coronary Artery Disease"

Digital cardiology is gaining power in the field of preventive cardiology recently, and several trials have already shown good results of dietary therapy with digital cardiology. However, there has been no reports that showed effect of dietary counseling through digital cardiology for secondary prevention of coronary artery disease. TeleDiet study investigates the impact of dietary therapy with a smartphone application on the content of meals and metabolic parameters for patients with coronary artery disease.

Hemodilution reduces concentrations of blood constituents: concentration of hemoglobin, red blood cells (hematocrit), physiological ions and coagulation factors that can contribute to impaired hemostasis and increasing the risk of perioperative blood transfusions. This pilot study will assess the feasibility of a large RCT to evaluate 2 techniques for reducing hemodilution during cardiac surgery: 1) retrograde autologous priming and 2) intraoperative mannitol. The aim of this pilot trial is to demonstrate feasibility of a larger trial to evaluate whether retrograde autologous priming and/or mannitol are superior to conventional priming alone.

Coronary artery bypass grafting (CABG) with cardiopulmonary bypass is a common surgical therapy for patients suffering from coronary artery diseases. The heart is subjected to a long period of ischemia due to the occlusion of the aorta. The heavy burden of myocardial ischemia-reperfusion injury (IRI) thus induces cardiomyocyte death, which can paradoxically reduce the beneficial effect of CABG. Preconditioning by moderate hypoxia or hyperoxia serves as an effective drug-free method to increase the organism's resistance to negative effects, including IRI.

Heart disease is the number one killer amongst chronic diseases around the world, and it is responsible for taking the lives of an estimated 17.5 million people each year. Exercise-based cardiac rehabilitation (CR) programs, which help heart patients improve their current health, prevent future heart problems, and improve their quality of life, are an effective strategy for lowering the risk of heart-related deaths in heart patients. CR programs currently have their patients perform moderate intensity, continuous exercise (MICE), which traditionally takes the form of walking, jogging, or cycling at a comfortable pace for 30-60 minutes. Recently, aerobic interval training (AIT), which involves performing short bouts of exercise, typically ranging from 15 seconds to four minutes at near maximal effort, followed by periods of recovery or rest, has emerged as a more effective strategy than MICE for lowering the risk of heart-related deaths in heart patients. Although these initial findings appear to hold much promise for improving CR programs in the future, it is important to recognize that women have been underrepresented or not included in these studies to date. Therefore, the goal of this study is to determine the effects of AIT versus MICE on the risk of heart-related death, blood vessel health, and brain health in women who have heart disease, and who have been referred to a six-month, outpatient CR program.

There is no evidence from prospective randomized clinical trials regarding the performance of conventional (two-catheter-concept; TCC) versus one-catheter-concepts (OCC) for invasive coronary angiography over the radial access. The aim of the present trial is to evaluate the efficacy and safety of different one-catheter concepts by use of the BLK and Tiger catheter compared to a TCC using standard Judkins catheters in diagnostic coronary angiography via transradial access. Patients with stable angina pectoris will be randomly assigned to coronary angiography performed with the BLK or Tiger (OCC) or Judkins catheters (TCC). The primary endpoint is coronary angiography duration.

Pioglitazone, a medication of thiazolidinedione group, is capable of triggering the peroxisome proliferator-activated receptors (PPAR-γ). Activation of receptor PPAR-γ regulates carbohydrate and lipid metabolism, immune and inflammatory responses in heart tissues. Our aim will to study the effect of pioglitazone on insulin resistance, the clinical course of atherosclerosis and coronary heart disease (CHD). The study will include 43 patients with coronary artery disease. Patients will be divided into the study group - 20 patients, in whom pioglitazone will be included in the combined therapy at a dose of 15 mg 1 time per day in the morning, and the control group - 23 patients receiving standard complex drug therapy over 6 months. Patients will be underwent clinical examination, ultrasound of neck vessels, study of carbohydrate and lipid metabolism. The end primary points of the study will be the onset of death due to myocardial infarction, coronary revascularization procedures (coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI)), or hospitalization for acute coronary syndrome (ACS) or unstable angina (UA). Predefined secondary end points included carotic atherosclerotic leisure (carotic intima-media thickness, diameter of stenosis, presents of atherosclerotic plaque), systemic inflammation level (the level of C reactive protein), lipid metabolism (levels of serum total cholesterol, triglycerides, high and low density lipoproteins), level of insulin resistance ( oral glucose tolerance test, blood glucose).

The object of the study is to determine whether different doses of PZ-128, when added to standard medical care in persons undergoing cardiac catheterization/percutaneous coronary intervention, will increase the risk of bleeding. A secondary objective is to determine whether patients treated with PZ-128 have fewer cardiac events such as heart attack, bypass surgery or stroke compared with those persons treated with the standard of care.

The primary objective of this study is to assess the safety and efficacy of the new-generation zotarolimus-eluting stent Resolute Onyx in the treatment of unprotected left main coronary artery disease (ULMCAD), both isolated or in association with two- or three-vessel coronary artery disease.

This is a First In Man study with the aim to know the safety and effectiveness of a novel bare metal stent (INC-1) in the treatment of de novo coronary lesions in patients with stable coronary angina and unique coronary lessions.

Purpose To investigate the effects of cardiac imaging radiation on the induction of DNA double-strand breaks by enumerating gamma-H2AX foci in blood lymphocytes and plucked hair follicle cells. To estimate whether the use of breast shields in cardiac computed tomographic angiography (CCTA) limits the effective radiation exposure of breast tissue.
