Filter by: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.
The use of fractional flow reserve (FFR) has improved outcomes in percutaneous coronary interventions (PCI) in patients with symptomatic stable coronary artery disease (CAD) with intermediate angiographic stenoses. It is a clinical tool used routinely in cardiac catheterization laboratories throughout the world including the Little Rock VA Hospital. The technique utilizes a pressure transducer constructed as part of an 0.014" guidewire. An FFR of >0.80 has been linked with myocardial ischemia found with nuclear stress and dobutamine echo stress testing. The FAME trial clearly demonstrated its value in improving long-term outcomes as compared to use of angiography alone. As such, the use of FFR is incorporated into both AHA ACC and European PCI guideline recommendations as part of routine care for intermediate lesions. A "work horse" guide wire is so defined because it can be used in most PCI cases. It combines a low tip load (to avoid intimal dissection, with excellent (ideally, one to one) torque transmission and trackability through tortuous lesions. Recently the FDA has approved an FFR guide wire, OptoWire, (Opsens, Quebec City, Quebec, CAN) which uses light transmission to measure pressure rather than electrical transduction wires. The primary purpose of the present study is to determine how effective this wire is as a work horse wire in patients in whom FFR is required. The OptoWire may also have the advantage of less "drift" occurring during the procedure. Drift refers to the change in pressure due to issues related to the wire and measuring system, rather than a true change in pressure. All current FFR wire systems demonstrate some degree of drift requiring measuring pressure of the wire in the aorta after the procedure is completed to determine if, and to what extent, drift has occurred. Thus, a secondary aim of this study will determine the degree of drift.
This is a prospective, observational, multi-center, single-arm, clinical trial designed to assess the efficacy of FFRangio in measuring FFR obtained from angiography compared to Invasive FFR for diagnosing hemodynamically significant coronary stenosis.
The main objective of this trial is to investigate the effects of starting exercise rehabilitation earlier than current practice after coronary artery bypass graft(CABG) or Aortic/Mitral valve replacement (VR) surgery.
The aim of this study is to find strategy for treatment through comparing the cardiopulmonary exercise test parameters before and after cardiac rehabilitation in patients with chronic total occlusion of the coronary arteries.
To determine associations between dietary factors and risk of major chronic diseases and their risk factors
The primary objective of the POST-PCI trial is to compare the clinical outcomes of a post-percutaneous coronary intervention(PCI) aggressive management strategy of routine noninvasive functional testing to a usual-care strategy of symptom-oriented functional testing in patients with high risk clinical, anatomical, and procedural characteristics who received PCI with contemporary drug-eluting stent and bioresorbable vascular scaffold.
Ischemic Heart Disease (IHD) is a condition of recurring chest pain or discomfort that occurs when a part of the heart is not receiving sufficient blood flow. It is a major public health concern internationally and in Singapore, the leading cause of death from cardiovascular disease. Cardiovascular magnetic resonance (CMR) has the ability to assess heart structures, scarring or lack of blood supply to the heart muscle with great accuracy and without any radiation involved. A CMR-compatible cycle ergometer can offer a safe and low cost stress equipment to assess heart function and motion abnormalities, and restrictions of the blood supply to the heart tissues due to partial or complete blockages of the blood vessels. This study aims 1. to develop an exercise-CMR stress protocol by testing its feasibility and robustness in assessing changes in cardiac volumes and function due to physical exertion in healthy individuals and 2. to assess the accuracy of the multiparametric stress-CMR as a diagnostic tool for ischemic-causing coronary artery disease (CAD) with coronary fractional flow reserve (FFR) as a reference. 3. to measure the overall economic impact of ischaemic heart disease by estimating the direct and indirect medical costs for each participant. The current sample costs will be extrapolated to estimate the annual costs of treating and managing ischaemic heart disease in the local population. 4. to evaluate the effects of coronary microvascular dysfunction on coronary flow and regulation, physiological response and cardiac sympathetic signaling in patients with chest pain.
The primary hypothesis of ROMA is that in patients undergoing primary isolated non-emergent coronary artery bypass surgery (CABG), the use of two or more arterial grafts compared to a single arterial graft is associated with a reduction in the composite outcome of death from any cause, any stroke, post discharge myocardial infarction and/or repeat revascularization. The secondary hypothesis is that in patients undergoing primary isolated non-emergent CABG, the use of two or more arterial grafts compared to a single arterial graft is associated with improved survival. Prospective event-driven unblinded randomized multicenter trial of at least 4,300 subjects enrolled in at least 25 international centers. Patients will be randomized to a single arterial graft (SAG) or multiple arterial grafts (MAG). Patients will be randomized in a 1:1 fashion between the two groups. Permuted block randomization with random blocks stratified by the center and the type of second arterial graft will be used to provide treatment distribution in equal proportion.
The aim of the Danish Organisation for randomised trials with clinical outcome (SORT OUT) is to compare the safety and efficacy of the ComboTM stent and Orsiro™ stent in the treatment of unselected patients with ischemic heart disease, using registry detection of clinically driven events.
