Filter by: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 overall goal of this project is to evaluate the clinical potential of fast quantitative myocardial tissue characterization using recently emerged Cardiac Magnetic Resonance Imaging (CMR) techniques to aid the diagnosis, treatment, and follow up of patients with myocardial diseases, such as ischemic heart disease, cardiomyopathies, and myocarditis.
Investigators aimed to investigate the association between over active bladder and coronary artery disease as demonstrated on coronary angiography.
The purpose of this study is to test the expression of microRNAs related to the syndromes after the intervention of Tongguan capsule,preliminarily to investigate the mechanism of the effects of Tongguan capsule, and provide the biological foundation of curative effect of Tongguan capsule.
It is known that laughter can bring benefits in terms of physiological and psychological parameters, in addition to improving the individual's quality of life. However, the literature is still scarce as to the existence of studies investigating the effects of a comedy film specifically in hemodynamics.
This is a pilot study randomizing patients with insomnia and coronary heart disease to either general sleep hygiene counseling and web-based cognitive behavioral therapy for insomnia versus general sleep hygiene counseling alone (followed by the cognitive behavioral therapy at a later date).
The objectives of this study are 1. To establish a prospective registry of the whole patients who received percutaneous coronary intervention with Xience Xpedition™/Alpine™ stent 2. To evaulate the long-term efficacy and safety of coronary stenting with the Xience Xpedition™/Alpine™ stent 3. To compare the long-term efficacy and safety of coronary stenting between the Xience Xpedition™/Alpine ™ stent and other contemporary drug-eluting stents which had established their own registry
New CZT-based SPECT cameras are potentially capable of dynamic 3-D acquisition. Preliminary results suggested that dynamic acquisitions could allow the assessment of myocardial flow reserve using 99mTc-labelled perfusion tracers. The Flow-Heart study will assess the feasibility of myocardial flow reserve measurement by means of 99mTc-DTPA dynamic cardiac SPECT in 20 patients.
HILLCLIMBER is a randomized, controlled, open-label phase II trial of moderate dose statin therapy (pravastatin 40mg daily) versus high-dose statin therapy (rosuvastatin 20-40mg daily) in HIV-infected persons taking antiretroviral therapy (ART) who have coronary heart disease (CHD).
To evaluate safety of reduction of dual antiplatelet therapy period to three months after implantation of Ultimaster sirolimus-eluting stent (U-SES). Additionally to investigate appropriateness of thienopyridine monotherapy with discontinuation of aspirin.
