Filter by:The safety and efficacy of percutaneous coronary revascularization has been progressively increasing since its inception, and the problem of restenosis has been minimized. The efficacy and safety data of the Magmaris stent are quite high, in selected cases. The objective is to evaluate the efficacy and safety of the bioabsorbable stent MAGMARIS in the percutaneous treatment of severe coronary disease (in vessels between 2.7mm and 3.75 mm) in routine clinical practice in poorly selected populations.
Recently, researchers have paid attention to the development of new products such as supplements food and nutraceuticals for identify and develop integrative therapies to be used in cardiovascular disease. As suggested by literature, some nutritional components (creatine, ribose) can enhance the fundamental energy levels for the functioning of the heart muscle and can enhance the body's antioxidant capacity through the reduction in free radicals activity, one of the main pathogenic mechanisms of these diseases. In this context, the investigators have developed a research with the principal purpose to establish whether a supplement of creatine and ribose can improve the total work capacity during exercise in a population of patients with known ischemic heart disease.
Atherosclerosis is accompanied by microvascular dysfunction (an impairment of blood vessels to dilate or constrict in response to demand). The ability to reliably measure microvascular dysfunction would help identify patients at risk of myocardial infarction and test new treatments. All existing measures of microvascular dysfunction suffer significant limitations. Near Infrared Spectroscopy (NIRS) is an imaging method that uses an infrared light-source and detector (called optodes) to painlessly shines light into tissue and collect reflected light at different wavelengths. This data allows quantification of the amount of haemoglobin (blood) in the tissue and whether it is oxygenated or de-oxygenated. Diffuse optical tomography (DOT) is a powerful analysis technique for data collected from multiple NIRH optodes. Unlike most NIRS studies that use a single pair of optodes and collects a single datapoint for each wavelength over time, DOT allows three-dimensional spatial reconstruction of haemodynamic and anatomic changes in a large region of tissue over time. In preliminary work DOT had the potential to measure forearm reactive hyperaemia, a key indicator of microvascular function. Team will test whether DOT can detect differences between patients and healthy volunteers. In this work, 30 patients will be recruited with type 2 diabetes, 30 patients who have had a previous myocardial infarction and 30 healthy volunteers. The Investigator will also recruit 50 patients who are on waiting lists for coronary angiography. The DOT will be used to measure participants' microvascular function after brachial artery occlusion by a blood pressure cuff. The Investigator will then examine whether DOT can detect differences between healthy volunteers, diabetics, and patients with a previous heart attack, and whether DOT is able to predict existence of coronary artery disease on angiography. If successful, DOT can be developed for assessment of microvascular function to the point where it could be applied to clinical studies.
The purpose of the Surveillance is to know the frequency and status of adverse device effects and adverse events in order to assure the safety of the new medical device, and to collect efficacy and safety information for evaluating clinical use results.
To assess the relationship between serum endostatin (ES) and Coronary artery calcification (CAC) in type 2 diabetic (T2DM) patients.
This is a Phase I study to investigate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of the novel compound, AZD5718 in healthy Japanese men. The results from this study will form the basis for decisions on future studies.
The objective of the study is to compare angiographic and clinical performance of Abluminus DES+ versus Everolimus-eluting DES in patients with diabetes mellitus.
The background for performing the present study is to compare the mass calculations by CT scanning and by invasive absolute blood flow measurements and thereby corroborating both methods.
This randomized, multicenter, prospective study seeks to compare left radial and femoral access during cardiac catheterization of patients with prior history of CABG surgery, with the primary objective of demonstrating that the two access techniques do not differ in the net procedure time (non-inferiority study) expanding the documented benefits of radial access to this group of patients.
We evaluated the effectiveness of a combination of a comprehensive health assessment consisting of the combination of a screening full body scan employing graphic patient education and motivational techniques followed by intensive, individualized behavioral training and management program on improved adherence to beneficial lifestyle behaviors, as well as possibly reduced risk of disease.
