iCorMicA - Stratified Medicine in Angina

Microvascular AnginaAngina9 more

The iCorMicA study is a multicentre, prospective, randomised, double-blind, sham-controlled, parallel-group, end-point trial and registry. The investigators seek to determine whether stratified medical therapy guided by an adjunctive interventional diagnostic procedure (IDP) during the invasive management of patients with known or suspected angina but no obstructive coronary artery disease improves symptoms, wellbeing, cardiovascular risk and clinical outcomes.

A Study to Evaluate the Safety and Pharmacokinetics of Regadenoson in Pediatric Patients

Myocardial IschemiaCoronary Artery Disease

This is a multi-centre, open-label, single-dose safety, tolerability and PK-pharmacodynamics (PD) study of the vasodilator regadenoson in 3 paediatric age groups for whom a pharmacologic stress perfusion CMR test is clinically indicated; adolescents aged 12 to <18 years (Cohort A), children aged 2 to <12 years (Cohort B), and infants aged 1 to <24 months and who weigh at least 3 kg (Cohort C). Regadenoson will be used as the pharmacologic stress agent in this study with MPI serving as both surrogate pharmacodynamic marker of the agent (MPR, MBF) and a clinically evaluable examination for the patient

Assessment of Patients With suspeCted Coronary Artery Disease by Coronary calciUm fiRst strATegy...

Coronary Artery Disease

The cost of medical care in the United States far exceeds that of all other advanced economies and continues to accelerate at a rate unacceptable to our society, due primarily to the high costs of new imaging technologies and novel drugs (1). Cardiac positron emission tomography (PET) imaging is a powerful new modality for the non-invasive detection of provocable coronary ischemia in patients with low to intermediate-risk chest pain or its equivalent. Intermountain Medical Center (IMC) is performing approximately 6000 clinical cardiac PET scans annually. However, cardiac PET scans are expensive (i.e., billed at >$5,000/scan, average receivable revenue $1500-$2000/scan). Coronary artery calcium (CAC) is a sensitive marker of coronary atherosclerosis. A CAC scan (CACS), performed by multislice computed tomography (CT), is a relatively inexpensive (~$70-$150/scan), low-radiation dose test that marks the presence of coronary atherosclerotic plaque. The absence of CAC has been shown to be associated with very low coronary risk. ACCURATE will test whether a CAC-first strategy (i.e., risk stratification, when CAC ≤ 1, to medical management or to cardiac PET stress testing), performed routinely in symptomatic patients presenting for evaluation of possible coronary artery disease (CAD) prior to the cardiac PET stress test, can be used as a gatekeeper for progression to the expensive rubidium-PET stress (regadenoson) perfusion scan and be a major cost-saver without adversely affecting patient care or outcomes. Routinely, qualifying patients undergo CACS when they present for evaluation of possible but unknown CAD status and are referred for cardiac PET stress testing. In ACCURATE, those with CACS≤1 will then be consented and randomized to either a cardiac PET stress test strategy or a non-PET-driven medical care strategy. Subjects randomized to the cardiac PET stress test strategy will receive appropriate subsequent care depending on the outcome of the cardiac PET scan (i.e., depending on whether ischemia is present or not). Subjects randomized to the CAC-only arm will receive appropriate non-PET driven medical clinical management and follow-up. All participating subjects' electronic medical records will be reviewed indefinitely for clinical outcomes. Initial outcomes will be reported at 1-year, 2-years, and 5-years, with future analyses to be determined by the study investigators. The objective of this study is to test the hypothesis that PET stress test strategy will results in a decreasing in major adverse cardiac endpoint without exceeding $100,000 per quality-adjusted life year compared to a CAC-first strategy for screening suspected/possible coronary artery disease.

CT Coronary Angiography for Type 2 Myocardial Infarction

Myocardial InfarctionCoronary Artery Disease

This study is to explore whether a computed tomography (CT) scan of the heart arteries might improve the care of patients that have presented with a suspected Type 2 myocardial infarction (MI). The Investigators hope to demonstrate that these patients may be the ideal group of patients to benefit from cardiac CT scan imaging by; 1. confirming whether they have any disease in their heart arteries 2. demonstrating the severity of the heart artery disease 3. revealing an alternative cause for their presentation 4. avoiding the need for an invasive heart artery angiogram.

Chronic Coronary Syndrome in Swedish Primary Care

Coronary Artery Disease

The goal of this clinical trial is to learn about a new procedure for investigation of possible coronary heart disease and to see if it is faster, cheaper or more expensive, promotes healthier behavior, mental well-being, adherence to drugs for heart protection and the risk for cardiac events like acute myocardial infarction over years to come. The novelty in the procedure is that a myocardial perfusion scan to assess blood flow to areas of the heart muscle, echocardiography i.e., heart ultrasound and heart CT scan comes as a "package investigation" performed on the same day. According to existing routines, "standard investigation" an exercise stress bicycle test is done, as well as an echocardiography and if needed the work up is completed by a myocardial perfusion scan. The main questions the trial aims to answer are: are the results from the procedure given to the patient faster with package investigation as compared to standard investigation? does the cost differ between the package and standard investigation group? does self-reported physical activity, physical fitness, dietary habits and mental well-being differ between the package and standard investigation group at start and after one, three and five years? does prescription of drugs taken for heart protection and adherence to the prescribed drugs differ between the package and standard investigation group after two and five years? does the risk for heart events like acute heart infarction differ between package and standard investigation after two and five years? Primary health care centers in Region Östergötland are randomly assigned to use either the new or existing procedure for investigation of possible coronary heart disease a so called cluster randomization. Patients who consult a physician at any of these primary health care centers are potential participants in the trial and are informed about the trial by written information, as they get their appointment for the medical investigation at either of two hospitals in the Region Östergötland. When the patient comes to the hospital for the investigations, he or she is asked to give written consent to the research i.e., to answer questionnaires now after one, three and five years, to let the researchers take part of the medical records, investigational results and data from medical registries over time.

Harmonizing Optimal Strategy for Treatment of Coronary Artery Stenosis- CloPidogREl for Primary...

Coronary Artery Disease

The investigators will evaluate the efficacy and safety of clopidogrel for primary prevention in patients diagnosed with coronary atherosclerosis on imaging that did not require revascularization therapy. The trial will test the hypothesis that clopidogrel is beneficial in preventing major adverse cardiovascular and cerebrovascular events (MACCE) in patients with subclinical coronary atherosclerosis identified on imaging.

Time Restricted Eating and Cardiac Rehabilitation

Coronary Artery Disease

This study will use a form of intermittent fasting called time-restricted eating (TRE) where individuals consume ad libitum energy intake within a set window of time, commonly 8 hours, which induces a fasting window of 16 hours per day (i.e., 16:8 TRE). TRE could be an effective addition to cardiac rehabilitation as it has demonstrated cardiovascular health benefits and potential for synergy when combined with exercise training. This study will determine if TRE is a feasible and safe nutrition intervention during cardiac rehabilitation and if TRE improves the health benefits of cardiac rehabilitation compared to cardiac rehabilitation alone.
