Filter by:This is a non-randomized, non-interventional pilot observational study designed to follow high-risk patients through their surgical and hospital stay. The investigators will collect 2 4ml vial's of blood (total of 8ml) prior to surgery to assess CV biomarkers - inflammatory, metabolic, hypercoagulable and platelet.
This study aims to compare antiarrhythmic drug therapy with catheter ablation using the SmartTOUCH catheter (Biosense Webster Inc.) as treatment for patients with ventricular tachycardia and coronary artery disease
Study in Vietnamese Patients with Coronary Heart Disease to investigate safety and P2Y12 Receptor Inhibition Effects of Ticagrelor and Clopidogrel
The proposed Phase I/II clinical trial will be used to determine the safety and toxicity of direct administration of the vector AdVEGF-All6A+ to the ischemic myocardium and to generate preliminary evidence regarding whether direct administration of AdVEGF-All6A+ to the ischemic myocardium will induce growth of collateral blood vessels and improve cardiac function. This is a three-part, multinational/multi-center, placebo controlled study.
The primary objective of this study is to characterize coronary artery blockages as determined by the LipiScan combined NIRS-IVUS catheter using multi-vessel imaging.
The current protocol for myocardial perfusion imaging (MPI) entails imaging within 30-45 minutes after radiotracer injection, for both rest and stress studies. We hypothesize that early imaging 10 minutes after radiotracer injection provides high image quality and diagnostic accuracy comparable to 30-45 minutes MPI.
The study will evaluate the use of Flurpiridaz F18 injection in patients with CAD to determine if the study drug in PET imaging is better than SPECT imaging currently used for this purpose.
This study is dedicated to determination of the long term effectiveness of coronary heart disease (CHD) treatments - cardiac shock wave therapy (CSWT) in comparison with other kinds of medical and surgical treatment. For that purpose the investigators will observe the patients with CHD who enrolled in this study in their routine course of treatment. But the investigators will not interfere with the patient treatment. Each participant will be followed-up for five years. The collected data will allow to determine if the particular method, CSWT, could really make any additional contribution to the more traditional methods of CHD treatment and if the CSWT is only temporarily effective or could exert the long term effect as well.
During coronary bypass surgery, veins are taken from the leg and applied to the heart and aorta to 'bypass' narrowings in the coronary arteries. However using an artery in the chest, the internal mammary artery, means that the bypass lasts longer than using veins. The investigators recently showed that using an artery from the arm as a bypass vessel, the radial artery, also had less furring up than veins 5 years after surgery. Now the investigators would like to ask patients to come back for an angiogram 10 years following surgery.
Left main stenosis use to be treated by bypass but with the improvement of angioplasty techniques, an increasing number of patients are submit to left main coronary angioplasty. Consequences of left main intra stent stenosis can be disastrous yet, for the moment, no precise recommendation concerning the follow up of these patients exist. The investigators ought to determine if stress echocardiography can predict left main intra stent stenosis as well (non inferiorly)as control angiography that use to be done.
