Active clinical trials for "Coronary Artery Disease"

This study aims at combining inspiration breath-hold myocardial perfusion SPECT with coronary CT angiography.

The objective of the study is to investigate clinical outcomes following single versus dual stenting strategies for the treatment of true bifurcation distal left main coronary artery lesions.

The HeartHab study is a pilot trial in which coronary artery disease patients (n = 15-30) are given the HeartHab application. The HeartHab application is a smarthphone based mobile application that serves as a secondary prevention tool, to support cardiac patients after their phase II cardiac rehabilitation program. During study period (4-6 weeks), participating patients will be asked to use the application. HeartHab includes a module devoted to therapy compliance, one to exercise training prescription and one to risk factor control. HeartHab aims to motivate the patient to improve his/her self-management skills and hence decrease cardiovascular morbidity (and mortality). Motivational aspects and usability data will be collected during study period by means of app logs and/or questionnaires/interviews.

This study is primarily designed to collect resting phase signals from eligible subjects using the Phase Signal Recorder (PSR) prior to coronary angiography to machine learn and test an algorithm for detecting the presence of significant coronary artery disease in symptomatic adult patient.

The CARDIOFLOW study compares the standard test, a pressure wire test called fractional flow reserve (FFR), with a new method that is based on taking a detailed "3D" ECG called Cardiogoniometry (CGM). FFR is an angiographic technique which measures the physiological significance of a coronary stenosis and trial data has shown that basing management decisions on this data improves prognosis. However FFR studies are expensive and invasive, whereas CGM is painless and simply involves placing 4 sticky pads to the patient's chest / back and is similar to an ECG (heart tracing). The investigators want to see whether we can use this new method to find out whether treatment with coronary angioplasty would be of benefit. If so, then in the future, clinicians could use this method (CGM) rather than pressure wire assessment (FFR). This would have several advantages; in particular, it can be easily performed in the clinic and avoids the need to use an expensive pressure wire.

The objective for this pilot study is to develop an optimized, clinically usable myocardial PET-MR perfusion protocol and to determine which of all data potentially available should be acquired for a clinical myocardial perfusion examination. Hypothesis: The hypothesis is that high resolution, high sensitivity DCE MRI could replace the rest PET myocardial perfusion imaging, significantly decreasing examination time and patient radiation dose while maintaining the comprehensive reference-quality PET myocardial stress perfusion coverage. The primary outcome will be comparison of diagnostic accuracy of each combination of imaging to detect clinically significant coronary artery stenosis (≥70% diameter stenosis).

The purpose of this study is to investigate if patients with coronary heart disease have higher risk to develop diabetes mellitus among the following two years. The examination of biomarkers taken from blood and fat issue shall provide which factors could be responsible for development of diabetes mellitus.

Ticagrelor therapy has been shown to reduce the rates of cardiovascular events and all-cause mortality compared to clopidogrel therapy in patients with acute coronary syndromes (ACS). The benefit of this study would be to demonstrate that ticagrelor therapy is associated with equivalent platelet inhibition irrespective of the disease status in patients undergoing PCI.

The purpose of this study is to compare three different revascularization strategies in patients with multi-vessel coronary disease: MICS CABG, OPCABG and ONCABG. The study hypothesis: MICS CABG (Minimally invasive cardiac surgery coronary artery bypass grafting) has advantages in comparison with conventional off-pump (OPCABG) and on-pump coronary artery bypass grafting (ONCABG) concerning major adverse cardiac and cerebral events (MACCE) and procedural success.

This is a pilot study to see whether cardiac imaging can be performed using half the standard dose of radioisotope.
