Filter by:Published data indicate that obstructive sleep apnea syndrome (OSAS) worse the prognosis of coronary artery disease (CAD) and that oxidative stress can link this 2 diseases. Investigators hypothesise that oxidative stress decrease after 3 months of continuous positive airway pressure (CPAP) in this specific population. The results may have major implication in the comprehension of physiopathologic processes linking OSAS and CAD and in the treatment of OSAS in this specific population.
This is a single center, randomized controlled trial which will include women with ischemic heart disease to receive either a self-directed stress reduction program delivered through a smart-phone application or activity tracking only for the first month ("early SR intervention" and "delayed SR intervention", respectively). Patients will be monitored for 1 month for application use and step counts via telephone or email interview and/or collection of screen-captured data. Baseline questionnaires will be repeated at the end of one month to assess for all primary and secondary measures, at which time the control group (activity tracking only) will be introduced to the intervention program. The early SR intervention group will not receive a new intervention but will be encouraged to continue using the app. Data will be collected for an additional 2 months with all participants in both groups. After the three-month study period, the study will close with the collection of final questionnaire data.
A randomised controlled trial to compare two strategies for the investigation of coronary artery disease at the time of angiography. Patients will be randomised to conventional angiography or additional, routine pressure wire assessment - measuring fractional flow reserve (FFR) - in all main vessels judged as being of sufficient vessel calibre to allow percutaneous coronary intervention (PCI) (experimental arm).
The purpose of this study is to evaluate the radiation exposure in patients undergoing coronary angiography, and to identify reference values for the main radiation doses parameters.
The purpose of the study is to find out if hybrid coronary revascularization (HCR) and coronary artery bypass grafting (CABG) procedure outcomes are similar. HCR is a combination of surgery and catheter procedures to open up clogged heart arteries. CABG is a surgical procedure to open up clogged heart arteries.
This project will benefit from the results of the concept study conducted from July to October 2014 from groups of coronary patients. This first study will help to develop the precise contours of Appet HEART application for the production of the prototype version used in the clinical feasibility study. The objectives of the feasibility study are: 1. assess the rate of use of the application 2. to determine the ideal target population of the application 3. to evaluate the effectiveness of the application 4. to measure the risks and potential limitations of its use 5. to determine the medical and economic impact of this application
The FUTURE-II study is a confirmative clinical trial for Sirolimus Target Eluting Bioresorbable Vascular Scaffold (Firesorb) after the feasibility and safety of the device has been preliminary confirmed in a small-scale First-in-Man clinical trial.
Ticagrelor is an oral, reversibly-binding, direct-acting P2Y12 receptor antagonist used clinically for the prevention of atherothrombotic events in patients with acute coronary syndromes (ACS). Guideline recommendations on the use of dual antiplatelet therapy have been formulated that ticagrelor 90 mg twice daily plus aspirin in preference to clopidogrel 75mg daily plus aspirin for ACS patients. However, few East Asian patients have been included in these trials to assess the use of these drugs. In addition, a growing body of data supported that East Asian might have different adverse event profiles (thrombophilia and bleeding) and "therapeutic window" compared with white subjects. But it is still not clear whether a low dose of ticagrelor is superior to clopidogrel in diabetic patients with stable coronary disease. Recent studies found that antiplatelet drugs might have anti-inflammatory effects and protect endothelial function. ACS patients treated by ticagrelor had a significantly higher increase in levels of circulating progenitor cells compared to those treated by clopidogrel, suggesting a benefit on endothelial regeneration that may participate in the pleiotropic property of the drug. This may prompt the regression of blood vessels and the endothelium stability. But it is not very clear that the effect of low-dose ticagrelor on vascular endothelial function in diabetic patients with stable coronary artery disease. Therefore, the investigators performed this randomized, single-blind clinical trial to observe the effects of different doses of ticagrelor and standard-dose clopidogrel on platelet aggregation and endothelial function in diabetic patients with stable coronary artery disease.
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.
Study on the registration of coronary heart disease patients undergoing PCI in Chinese's population. Get the incidence of adverse events in these patients after PCI, a clear type of adverse reaction, forms, influencing factors, to establish risk management processes, clinical safety and reasonable treatment, and provide the basis for further research and reference.
