Active clinical trials for "Coronary Artery Disease"

This study will test the hypothesis that the anti-gravity treadmill can be safely used in stress nuclear myocardial perfusion imaging in patients unable to perform conventional treadmill exercise. This will be foundational evidence on which to consider a larger clinical trial to show that the anti-gravity treadmill improves diagnostic specificity across all cardiovascular stress testing modalities including treadmill-alone, exercise stress echocardiogram, exercise SPECT as well as having implications for cardiac PET and MRI in the future.

This is a preliminary, open-label, clinical trial designed to assess the efficacy, safety, and tolerability of vortioxetine for the treatment of major depressive disorder in patients with coronary artery disease. In addition, the study will assess the effects of vortioxetine on heart rate variability in these patients.

The purpose of this study is to understand the effects of a mobile health cardiovascular prevention program in patients who have recently graduated from cardiac rehabilitation. The mobile health program will focus on promoting healthy lifestyles through the use of a mobile application (app), mobile physical activity monitor and a system of remote health coaching. By testing a novel mHealth intervention focused on lifestyle modification, this trial will address a critical evidence gap in the care of patients after they graduate from CR. Many patients who graduate from traditional CR struggle with unhealthy lifestyles, and these patients currently have no lifestyle-based care strategies to help them. The results of this study have the potential to lead to new sustainable and resource-efficient, lifestyle-based preventive care strategies for patients with stable CVD.

Computed tomographic angiography (CTA) is an important prognostic tool with regard to the detection of coronary artery stenoses. Both iodine delivery rate (IDR; the amount of iodine delivered to the patient per second) and iodine concentration are decisive factors in the opacification of arterial vessels. There remains to be some debate in the literature about whether the use of high iodine concentration contrast media is beneficial compared to lower iodine concentrations. To date, there have not been any studies comparing intracoronary attenuation using concentrated contrast media lower than 300 mg I/ml at coronary CTA. For a reliable comparison of CM with different iodine concentrations, adapted injection protocols insuring an identical IDR (in g iodine per second) are mandatory. The investigators hypothesize that usage of lower iodine concentrations, while maintaining identical IDR and total iodine load, will result in comparable diagnostical intra-vascular attenuation in CTA.

Despite the routine use of procedural anti-coagulation and anti-platelet therapy for FFR calculation, no study has evaluated the optimal anti-thrombotic regimen in patients undergoing FFR. Therefore, the aim of the Evaluation of Simplified Anti-Thrombotic Therapy for Coronary Fractional Flow Reserve (SMART-FFR) study was to evaluate the safety of using a simplified anti-thrombotic regimen with only upstream dual anti-platelet therapy (DAT) with aspirin and clopidogrel, compared with anticoagulation plus single- or- DAT therapy in patients with intermediate coronary artery stenosis undergoing FFR calculation during elective coronary angiography.

The investigators attempt to investigate the organ protective effect of remote ischemic conditioning in patients undergoing non-cardiac surgery with history of ischemic heart disease.

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.

The recurrence of major cardiac events after infarction is very high, in some populations up to 20% in the first year. Optimal secondary prevention as organized in cardiac rehabilitation centers is effective in reducing both morbidity and mortality. However, many studies have shown that the participation and adherence rate in CR-programs is low in most European countries. Therefore, novel ways of delivering secondary prevention using information technology and self-monitoring are being explored. Hence, this study will investigate the effectiveness of a mobile, patient tailored, app based multidisciplinary telerehabilitation program (HeartHab app) in improving exercise capacity, lifestyle and risk factors in patients with coronary artery disease in a post-rehabilitation setting.

The purpose of this study is to evaluate the feasibility, tolerability, safety, and image quality of low-radiation, dynamic perfusion CT of the heart in patients with suspected ischemic chest pain and a moderate or severe stenosis seen on coronary CTA. Secondary aims include the assessment of the diagnostic accuracy of CT perfusion imaging compared to either SPECT or invasive angiography.

This is a single-center, pilot study that will evaluate the effectiveness of the AHA science based CarePlans and the Ambio Health technology in improving the risk adjusted 30 day readmissions rate, patient compliance, and biometrics. The study will also be used to assess the feasibility of similar heart failure transition programs in the future.
