Active clinical trials for "Coronary Artery Disease"

To evaluate the safety and efficacy of the Absorb BVS System compared to the XIENCE V Everolimus Eluting Coronary Stent System (EECSS) in the treatment of subjects with ischemic heart disease caused by up to two de novo native coronary artery lesions in separate epicardial vessels.

A cold season involves higher cardiovascular morbidity and mortality. Several epidemiologic studies have implicated that persons with a cardiac disease, such as coronary artery disease (CAD) may be at higher risk for these adverse health events, but the mechanisms are not well established. Because both exercise and cold exposure stimulates cardiac and circulatory functions it is important to study their interaction especially among people with CAD and whose myocardial oxygen supply and function are weakened. The study examines how recommended health-enhancing upper and lower body exercise and warm-up in combination with cold exposure affects cardiovascular functions of people with CAD. The research includes randomized controlled experiments where the participants are 35-75 year old men with CAD (CCS I-II) and recruited from the Oulu University Hospital. Each participant undergoes four different trials in random order where the temperature (+22°C or -15°C) and the form of exercise (brisk walking at 5.5 km/h or upper body exercise at 30 W), and warm-up regime is varied. The used exercise, clothing and exposure resemble an ordinary wintertime exercise event. Novel techniques are used to broadly assess cardiovascular function before, during and in the recovery phase. The obtained information is synthesized and translated to tailored year-round exercise instructions for people with CAD by the research team including experts from sports sciences, physiology, public and occupational health, clinical sciences and with complementary knowledge in physical activity, effective interventions and cardiovascular function. The study has broad national and international impact on the relatively passive aging population having CAD and residing and working in a cold climate. The produced information enables finding means to activate persons with CAD and where appropriate and safe year-round exercise may reduce or prevent adverse health effects. Health care personnel will have an improved possibility to prescribe physical activity programs for their clients and enabling better instructions of healthy and safe exercise as a way to promote health.

The study is a two-arm, parallel, randomized clinical trial. The purpose of the study is to evaluate the effectiveness of automated mobile phone text message-based intervention for secondary prevention, including lifestyles modification, medication adherence improvement and risk factors control among coronary heart disease (CHD) patients without diabetes. The participants will be randomized into intervention and control groups in a 1:1 ratio. The intervention group will receive 6 pre-designed text messages per week in addition to usual care for 6 months, while the control group will receive usual care.

Aims and objectives: To determine the effect of position change that is applied after percutaneous coronary intervention on vital signs, back pain, and vascular complications. Background: In order to minimize the post-procedure complications, patients are restricted to prolonged bed rest that is always accompanied by back pain and and hemodynamic instability. Design: Randomized-controlled quasi experimental study Methods: The study sample chosen for this study included 200 patients who visited a hospital in Turkey between July 2014 and November 2014. Patients were divided into two groups by randomization. Patients in the control group (CG, n = 100) were put in a supine position, in which the head of the bed (HOB) was elevated to 15°, the patient's leg on the side of the intervention was kept straight and immobile; positional change was applied to patients in the experimental group (EG, n = 100).

Low motivation to exercise is one of the barriers to participation in cardiac rehabilitation. Fear of activity after a cardiac event is associated with low levels of physical activity. This study aimed to develop and validate a scale to measure fear of activity in patients with coronary artery disease.

Identifying the critical lesion of coronary artery disease and determining the interventional plan are significant for reducing adverse cardiovascular adverse events. The assessment of critical lesion requires the consideration of plaque morphology, tissue composition, and endometrial stress which leading to rupture. In summary, accurate assessment of critical lesions has high application value. In this study, patients with critical coronary artery disease were divided into two groups: an accurate assessment group and a simple assessment group, with the aim to compare the diagnosis and treatment efficiency as well as prognosis, potential cardiovascular risk, possible "excessive" intervention.

Medical scientists have found that people with diabetes who take the drug Metformin have less age-related disease than those taking other treatments and researchers believe it may prevent numerous diseases and conditions that effect older people. In addition, metformin extends lifespan in some animal models of human disease. The purpose of this study is to see if taking Metformin causes changes in blood cells consistent with improved health and longevity in people who do not have diabetes. In this study Metformin will be compared to placebo. A placebo is a substance, like a sugar pill, that is not thought to have any effect on a participants disease or condition. In this study participants will either receive the active study medication, Metformin or placebo which is not active. Placebos are used in research studies to see if the drug being studied really does have an effect.

The aim of the study is to evaluate the influence of physical training and respiratory rehabilitation performed by patients at home on quality of life, symptoms, physical endurance, force of respiratory and skeletal muscles and body mass composition in patients with pulmonary arterial hypertension (PAH) or left ventricular heart failure with reduced ejection fraction - HFREF), or ischemic heart disease and evaluation the number of stem cells, natural lymphoid cells and distribution of subpopulations of monocytes (including proangiogenic monocytes) in examined persons and evaluation of theirs eventual influence of the course of disease.

The present study will investigate the volume and extent of the expected physiological effects of "early mobilization" on the prevention of the clinical illness' detrimental sequelae and on the functional recovery promotion of CABG, AVR and MVR patients. Consequently, it will investigate if the improved health outcomes may limit the number and intensity of complications and thus if it may speed up hospital discharge.

Off-pump coronary artery bypass grafting (OPCABG) is a bypass method performed on the working heart. Pain is a frequently seen side effect experienced following this surgery. Erector spinae plane block is our analgesia method that the investigators routinely perform prior to the surgery to overcome this problem. In this method, analgesic medication is given via a needle in between the two superficial muscle groups (erector spinae muscles) located in participants back. The investigators believe this method not only provides pain relief, but also is beneficial (dilating) on the vessels that will be used for bypassing the clogged vessels during the surgery. The investigators aimed to measure some parameters in this routine procedure before and after performing the analgesic method with an ultrasound (imaging with sound waves).
