Filter by:A prospective single clinical trial to validate the use of a low-dose (~5mSv) Tc-99m protocol with a high-efficiency cardiac dedicated camera (Dynamic Single Photon Emission Computed Tomography; D-SPECT) to detect myocardial perfusion abnormalities during myocardial perfusion imaging.
To validate the use of Corus CAD (Age/Sex/Gene Expression score - ASGES) blood assay in subjects who are referred for the work-up of coronary artery disease. The study will evaluate the clinical utility of a gene expression test Corus CAD (Age, Sex, Gene Expression Score - ASGES) in subjects referred for myocardial perfusion imaging (MPI) work-up for suspected obstructive atherosclerotic coronary artery disease (CAD). The Corus CAD (ASGES) is a gene expression test that quantify the expression of multiple genes from circulating peripheral blood cells to detect the presence of clinically significant obstructive CAD in patients with chest pain.
The purpose of this study is to determine whether care as usual or intervention (consisting of sertraline versus placebo), are effective in the treatment of panic disorder and/or depression driven noncardiac chest pain.
We are doing a study to assess the impact of including patients in making decision regarding their own medical care in the emergency department. We will randomly assign them to either receive a decision aid or usual care. In doing this, we aim to increase patient satisfaction and safely decrease medical cost.
The use of coronary angiography to investigate patients at risk of coronary artery narrowings has become universal. In most cases, this investigation leads to a successful treatment plan with revascularisation recommended where appropriate. However in a substantial number of patients, the images taken of the coronary arteries can lead to diagnostic uncertainty. Increasingly, doctors are using devices called pressure wires to clarify the significance of coronary artery narrowings in order to tailor patient treatment on an individual basis. The Radi pressure wire is well recognised as a reliable tool in assessing whether a narrowing is significant in functional terms, that is, does it significantly restrict blood flow to the heart muscle.It consists of a fine wire that is fed into individual major coronary arteries to measure pressure within the vessel itself. In conjunction with the images taken of the arteries, it is very useful in deciding how best to treat patients. This study enrolls volunteers who are being investigated for stable cardiac-sounding chest pain and are undergoing a coronary angiogram. It will investigate whether the extra information gained from pressure wire assessment will change patients' treatment plan.
The purpose of this research is to determine the efficiency of a single dual source computed tomography (CT-DSCT) protocol to establish or exclude acute coronary syndrome (ACS), pulmonary embolism (PE) or aortic dissection (AD) as compared to the individual protocols. Endpoints aim to compare the rate of emergency department (ED) discharge, length of hospital stay, the diagnostic imaging test utilization, and the costs between the comprehensive and the standard protocol strategy in patients with undifferentiated chest discomfort or shortness of breath with a component of chest discomfort.
Clinical decision units (CDUs) improve resource utilization and are a recommended care option by the American College of Cardiology / American Heart Association, but are underutilized in non-low risk chest pain patients due to weaknesses of traditional cardiac testing. Cardiac magnetic resonance imaging (CMR) is sensitive and specific for ischemia, can simultaneously assess cardiac function and myocardial perfusion, and could revolutionize the diagnostic process for intermediate risk patients with chest pain. The primary objective of this trial is to measure the efficiency and safety of a combined CDU-CMR care pathway compared to inpatient care among patients with non-low risk acute chest pain.
The purpose of this study is to demonstrate the relative bioavailability of Nadolol (1 x 80 mg) tablets under fasting conditions.
This multi-center, randomized, controlled trial conducted in Emergency Departments (ED) compares computed tomography (CT) coronary angiography with the traditional approach (usual care) for low- to intermediate-risk chest pain patients. The primary objective is to estimate the rate of major cardiac events (heart attack or cardiac death) within 30 days in trial participants in Group B who were not found to have significant coronary artery disease by CT coronary angiography. Additional evaluations will comprise health care utilization assessments, including length of hospital stay and re-admissions, cost analysis, and 1-year post-triage/presentation major cardiac event rates.
The purpose of the study is to establish an overarching database of information containing historical, demographical, clinical, and intermediate and long-term outcome data from all William Beaumont Hospital (WBH) patients undergoing Cardiac Computed Tomographic Angiography (CCTA) testing for clinical or scientific reasons.
