Active clinical trials for "Coronary Artery Disease"

The purpose of this study is to elucidate the imaging mechanisms of cognitive function changes in patients with coronary heart disease before and after surgery or conservative treatment, and to evaluate and predict the postoperative neurological function recovery and cerebrovascular health level of patients by combining serum markers and patient cardiovascular health evaluation indicators.

The overall purpose of this research study is to identify the disparity in ischemia measurement between fractional flow reserve (FFR) used in the cardiac catheterization laboratory and myocardial perfusion stress- single-photon emission computed tomography (SPECT). This study aims to determine the correlation between simultaneous FFR and SPECT obtained using regadenoson in the catheterization laboratory.

Chronic inflammatory activation in fat tissue can be the link between adiposity and an increased risk for atherosclerosis. The aim of this study is to investigate how molecular alterations in fat tissue can be influenced by regular physical exercise training alone or in combination with a medical therapy (glitazone or metformin) in obese patients with severe coronary artery disease (CAD) and impaired glucose tolerance.

To compare computed tomography (CT) images (pictures) of the coronary arteries using the General Electric (GE) LightSpeed VCT scanner with x-ray coronary angiography in patients referred for an x-ray coronary angiography.

While there are features on a CCTA that are correlated with plaque vulnerability and can be reported on, this is not always done. This is important as it is thought that vulnerable plaques present the greatest risk of myocardial infarction. This study will assess the correlation between software and human classification of these plaques, as well as demonstrating the time efficiency of AI reporting when compared to a clinician.

Assess the usability and acceptance of the P-STEP app, through allowing participants with specific chronic conditions to pilot the app for 12-weeks.

The CTO-DENOVO study is a multicenter registry of consecutive patients with de novo CTO undergoing successful CTO recanalization with the use of DCB-only strategy. The primary endpoint is target lesion failure at 6 months. The secondary endpoints are: 1) late lumen loss on follow-up angiography, and 2) minimal lumen area on follow-up intravascular ultrasound.

This is a single-center, double-arm, open-label, randomized feasibility study that will determine whether a novel clinical decision aid accessed via the electronic health record will be acceptable to both cancer survivors and their cardiologists, will favorably impact appropriate medication use and cardiac imaging surveillance, and will improve clinician and patient decision-making, perception, and behavior towards cardioprotective medication usage and cardiovascular disease imaging utilization.

True coronary bifurcation lesions are still great of interest due to their complex anatomy, uncertainty of optimal stenting strategy and increased adverse cardiovascular outcomes. Provisional stenting is recommended in patients with non-complex coronary lesions while 2-stent strategies should be considered in complex coronary bifurcation lesions. However, optimal 2-stent strategy is still controversial. Double kissing (DK) crush stenting is the prominent technique in true bifurcation lesion, especially in patients with left main coronary artery disease. DK mini-culotte stenting, increasing use in clinical practice, has become popular over DK crush stenting. It was demonstrated in a bench test that stent malapposition was lower in the DK mini-culotte stenting compared to the DK crush technique. Thus, DK mini-culotte stenting may be preferred over DK crush stenting in complex true coronary bifurcation lesion. On the other hand, it was demonstrated in previous studies, less than minimal protrusion (generally called as nano protrusion) had better clinical outcomes. Kawasaki et al was first demonstrated the minimal (nano) protrusion of culotte stenting technique. Then, Toth et al revealed a novel modified culotte stenting technique named single string culotte. There was no major adverse cardiac events (MACE) in patients underwent single string stenting technique with a median follow-up period of 6±4 months. Unsurprisingly there was no MACE occurred in patients who underwent Szabo 2-stent technique. In the light of foregoing data, the least possible amount of protrusion is known to have the best results. In addition to this, double kissing balloon dilatation with culotte stenting technique seems to have better results than other stenting techniques. In our study, we aimed to evaluate the angiographic and clinical results of a novel DK Nano-Culotte stenting in coronary bifurcation lesion.

The purpose of this study is to assess the engagement and usefulness of Care4Today® Connect CAD-PAD digital platform in participants with coronary artery disease or peripheral artery disease (CAD or PAD).
