Femoral artery approach to perform coronary procedures is considered the standard technique for vascular access due to optimal catheter control, lower thromboembolic complications and immediate access due to the large diameter of the artery. Trans-radial approach has been shown to reduce major bleeding complications, vascular complications related to the site of puncture, including death from all causes, and to prevent post-procedure limb rest, greater comfort for patients, immediate ambulation, early discharge and reduction of costs. Previous studies have shown that intravenous, topical and intraarterial use of nitroglycerin produces vasodilation of the radial artery. Extravascular (subcutaneous) administration of nitroglycerin is extremely effective in restoring the radial pulse, and allows adequate cannulation.
This study is to assess the clinical non-inferiority of 1 month (short-term) vs 6 months (long-term) of dual anti-platelet therapy in patients undergoing percutaneous intervention implanted sirolimus -eluting stent with abluminal grooves containing a biodegradable polymer in High Bleeding Risk patients with coronary artery disease.
Women with heart disease are more likely to die or suffer another cardiac event or stroke within 5 years of an index event compared to men. They are also more likely to suffer depression and report lower quality of life. Cardiac Rehabilitation programs have been designed to address these issues, but most women do not attend. Women indicate they have a greater need to talk about their experiences with heart disease and seek social support to help them cope. Peer support, the assistance provided by other women with a similar illness experience, may be one way to enhance social support for women with heart disease and help them improve their psychosocial well-being. The Investigators have developed a peer support program called Women@Heart (W@H). The program is led by trained peer leaders (women who themselves have made a successful recovery from a heart event). A pilot test of the program showed promising results. The Investigators now need to conduct a more rigorous evaluation of the program. The main objective of this project is to determine if the W@H program helps women to improve their psychosocial well-being compared to being on a waiting list to participate in the program. It will also examine the effect of the program on: health behaviours (tobacco smoking, physical activity, sedentary behaviour, fruit and vegetable consumption, and medication adherence); coronary risk factors; and clinical outcomes (re-hospitalization, health care system use, death).
This translational study was designed to explore the association of the quantity and quality of epicardial adipose tissue (EAT) with coronary artery disease (CAD), left atrial remodeling and postoperative atrial fibrillation in a high cardiovascular disease-risk population. The investigators expect to identify new biochemical factors and biomarkers in the crosstalk between the epicardial adipocytes, coronary plaques and atrial cardiomyocytes that are involved in the pathogenesis of atherosclerosis and atrial fibrillation, respectively.
The trial was designed in such a way as to show that the proposed program "Trust" increases the proportion of patients who adhere to therapy in the cohort of those with coronary heart disease for two years after successful revascularization by using thrombolytic or stenting of the coronary arteries against the background of myocardial infarction.
Epicardial adipose tissue (EAT) is the visceral fat of the heart. EAT could locally affect the coronary arteries through local secretion of pro-inflammatory cytokines. EAT plays a role in the development of the coronary artery disease (CAD). EAT is a highly enriched with genes involved in inflammation. Given its rapid metabolism and simple measurability, as first developed by Iacobellis, EAT serves as target for medications targeting the fat. Glucagon-like peptide-1 agonists (GLP-1A) are anti-diabetic medications with recently suggested cardio-protective properties. Liraglutide, a GLP-1A, has recently shown to reduce the cardiovascular risk. Iacobellis'group found that EAT thickness decreased by an unprecedented 36% after 12 weeks of treatment with liraglutide. Remarkably, Iacobellis'group found for the first time that human EAT express GLP-1 Receptor (GLP-1R). GLP-1A effects may be therefore visceral fat specific and target EAT. Based on these preliminary data, we hypothesize that treatment with liraglutide will significantly and rapidly reduce EAT inflammation. Decreased EAT inflammation can reduce the burden of the coronary plaques. We will test our hypothesis in a 12-week randomized, double-blind, placebo-controlled, interventional study in 40 patients with type 2 diabetes mellitus (T2DM), and CAD, with an acceptable glycemic control on their current diabetes regimen who require elective coronary artery bypass graft (CABG) regardless of their participation in the study. A minimum time frame of 4-week treatment will be considered to detect significant changes in the study endpoints. Inclusion criteria for body fat markers will rule out the confounding effect of different body fast distribution at baseline. Study subjects will be randomized in two groups of 20 patients to receive additional liraglutide or to remain on current treatment/ placebo prior to cardiac surgery. CAD subjects not allocated to liraglutide will be started on a supervised low calorie diet (LCD) to achieve approximately 5% of weight loss after from a minimum of 4 weeks up to 12 weeks to avoid the confounding effect of weight loss on the study outcomes. EAT samples will be collected during cardiac surgery and processed for analysis of mRNA and protein expression of EAT inflammatory genes such as Tumor Necrosis Factor-alpha (TNF-α) and Interleukin 6 (IL-6), and GLP-1R.
To test the feasibility and diagnostic accuracy of a new automated pressure derived resting index (Pd/Pamin), using FFR as gold standard, in de novo coronary lesions in which invasive physiological evaluation is warranted.
Little is known about the hyperemic efficacy of IV adenosine as well as safety in patients with heart failure with reduced ejection fraction (HFrEF) because they were excluded from the major FFR studies. We will evaluate the feasibility and hyperemic efficacy of IV adenosine in patients with HFrEF in comparison with IC nicorandil for invasive physiological assessment using a coronary pressure wire.
We aim to enroll subjects eligible to cardiac rehabilitation that are defined as low-risk according to national guidelines. We plan to gradually reduce the number of institution based CR and increase the tele monitored exercise sessions performed in the community. Stress test will be preformed before the intervention and after completing 6 month.
