Filter by:Purpose: The purpose of this study is to examine cerebral oxidative and inflammatory stress and cerebral hemodynamics during and after coronary artery bypass grafting and correlate with postoperative cognitive function.
The purpose of this study is to determine the effects of a physiotherapy prehabilitation programme (walking and deep breathing exercises) in cardiac or thoracic patients by measuring changes in lung volumes, functional capacity physiotherapy length of stay postoperatively.
The purpose of this study is to understand routine use of FFR (Fractional Flow Reserve) and alternate indices in clinical practice. This study will determine the use and clinical outcome of FFR-guided PCI in patients presenting with either stable coronary artery disease, or in patients presenting with Acute Coronary Syndrome (ACS) on culprit and non-culprit lesions as well as during index and secondary procedures.
The purpose of this study is to determine whether high intensity interval training (INT) is more effective in suppressing platelet reactivity than continuous, moderate intensity training (CONT) in patients undergoing cardiac rehabilitation after percutaneous coronary intervention.
A total of 30 subjects with moderate to severe atopic dermatitis. Thirty subjects without AD matched for sex, age and coronary artery disease risk factor with the AD subjects will also be included. All subjects will undergo the following imaging procedures: a 18FDG-PET to quantify vascular inflammation in the ascending aorta and carotids and a MDCT to calculate the Agatston score. Skin and blood biomarkers will also be assessed.
The goal of this study is to use three (3) different imaging techniques:Fractional Flow Reserve (FFR) allows precise measurement of blood flow in the arteries to the heart, and is more reliable than pictures alone to determine the significance of blockages in the heart; Near Infra-Red Spectroscopy-Intravascular Ultrasound (NIRS IVUS) provides information about the amount of lipid and cholesterol in the plaque, and plaque volume; and Optical Coherence Tomography (OCT) allows physicians to assess tears in the surface of plaque and plaque thickness; to evaluate high risk non-infarct-related coronary lesion in patients who have suffered a recent heart attack, underwent successful opening of the artery with a stent, and have blockages greater than or equal to 50% in one or more of the other arteries to the heart; and to correlate this findings with cardiovascular outcomes at 1 year.
Effect of Vascepa on Progression of Coronary Atherosclerosis in Persons with Elevated Triglycerides (200-499) on Statin Therapy. The study is to determine progression rates of low attenuation plaque under influence of Vascepa as compared to placebo.
To evaluate the benefits of Ayurvedic SUVED & REIMMUGEN Colostrum for reduction/reversal of symptoms and study clinical progress in Vascular disease; CAD, CAV, Stroke, DVT patients.
To define and evaluate the impact of angiographic coregistered OCT on physicians decision-making through prospective data collection in PCI procedures.
Background Endothelial dysfunction is one of the early events in atherosclerotic plaque development. It is characterized by an increased ratio of substances with vasoconstrictive, pro-thrombotic, and proliferative properties over substances with vasolidatory, antithrombogenic and antimitogenic properties. Endothelial dysfunction is also associated with high-risk patients with coronary artery disease. Hyperglycemia, obesity, hypertension and fat mass also impair the endothelium by increasing the expression of cytokines, inflammatory markers and vascular markers. Hypothesis Administration of dapagliflozin in addition to metformin background with clinical or subclinical cardiovascular atherosclerotic disease improves endothelial function when compared to those using glibenclamide in addition to metformin. Objectives Evaluate the effect of dapagliflozin vs glibenclamide on a metformin background on endothelial function in patients with clinical or subclinical cardiovascular atherosclerotic disease and poorly controlled diabetes. Enpoints Prymary Change in flow mediated dilation (FMD) and its related endpoint (FMD post reperfusion lesion) between the randomization visit and over 12 weeks of treatment. Secondary Change in plasma nitric oxide, isoprostane, ICAM-1, VCAM-1, ET-1, leptin, adiponectin, C-reactive protein, TNF- α, interleukin-6, interleukin-2, weight and body composition (% of fat mass and % free fat mass) at the randomization visit and over 12 weeks of treatment. 3 Design Randomized, parallel-group, comparative, prospective clinical study. The study is divided in two phases: Run-in and Randomization. In the former phase, which must have the maximum period of 16 weeks, patients will visit the outpatient to adjust metformin and blood pressure medications. After run-in phase, patients that fulfill inclusion criteria will perform an ambulatory blood pressure monitoring (ABPM) in order to asses BP; body composition will be assessed by dual x-ray absorptiometry (DXA); endothelial function as assessed by flow mediated dilation and vascular cytokines. Patients will by randomized to dapagliflozin or glibenclamide on a metformin background. After 12 weeks, the ABPM, DXA and endothelial function will be assessed.
