Filter by:To determine the ability of semi‐automated plaque assessment in cardiac computed tomography angiography (CCTA) and high sensitive troponin T (hsTnT) for the risk stratification of patients at intermediate risk for coronary artery disease (CAD).
This registry is a clinical evaluation of the Orsiro LESS in subjects requiring coronary revascularization with Drug Eluting Stents (DES). It is designed to investigate and collect clinical evidence for the clinical performance and safety of the Orsiro Drug Eluting Stent System in an all-comers patient population in daily clinical practice.
Clinical evaluation of the Orsiro LESS in subjects requiring coronary revascularization with Drug Eluting Stents (DES). 500 subjects will be enrolled in this registry. The sample size maybe increased in order to reach the subgroup sizes (Diabetes, small vessel, AMI and CTO).
This is an observational registry, sponsored by Saint Luke's Hospital. This study is to be conducted according to DHHS Guidelines, applicable state regulations, and local IRB policies and procedures. The overall objective is to address current gaps in knowledge regarding CTO-PCI, as a prospective, multi-center, single-arm study of 1,000 participants.
The purpose of this study is to investigate the effects of exercise for patients with coronary artery disease (CAD) aged 80 years and older, with special reference to maximum aerobic capacity, muscle endurance, physical functioning, level of physical activity, health related quality of life, anxiety, depression and endothelial function, compared to a control group.
The aim of the study is to prove that early discharge (within 72 hours) in selected group of patients after myocardial infarction with elevations of ST-segment is feasible and safe
Chronic total occlusions (CTO) are encountered in almost one-fourth of patients undergoing coronary angiography. The presence of an untreated CTO has been related to adverse clinical prognosis, both in stable angina and acute myocardial infarction, and is often associated with persistent symptomatic angina. Depending on their symptomatic and functional status as well as anatomical complexity, CTO can be treated by optimal medical therapy only or therapy combined with coronary revascularization. The potential benefits of percutaneous coronary intervention (PCI) in CTO include symptom relief, improved left ventricular function, and potentially a survival advantage associated with success when compared with failed revascularization. Of note, marked advances in endovascular techniques and device technology have resulted in substantial improvements of procedural success rates of PCI in CTO. In spite of these advances, the vast majority of patients with CTO are still being managed medically or referred for coronary bypass surgery rather than PCI. The most common reason for deferring PCI in patients with CTO appears to be the uncertainty of predicting the procedural outcome of percutaneous revascularization. Further barriers to attempting CTO by PCI include the difficulty of gauging the time required for the procedure and the use of resources. The CT-RECTOR (Computed Tomography REgistry of Chronic Total Occlusion Revascularization) study was designed to evaluate the application of coronary computed tomography angiography (CTA) for the prediction of procedural outcome of PCI in CTO in an international patient population. The main purpose of this multicenter registry is to develop a noninvasive CTA-based prediction tool (CT-RECTOR Score) for grading CTO suitability for PCI.
Clinical trial phase III, prospective, controlled, randomized, open. We hypothesize work that patients with chronic coronary occlusion and poor myocardial viability who failed to recover ventricular function after subjecting coronary revascularization with new techniques of recanalization, could achieve an improvement of ventricular function if given further regenerative treatment with mononuclear cells from autologous bone marrow. To test this hypothesis we designed a prospective, randomized clinical trial in patients with recanalized chronic occlusions and ventricular dysfunction.
To evaluate the introduction of Percutaneous Coronary Intervention without Onsite Surgery in the largest state, California (CA) began a pilot PCI program in 6 hospitals without onsite cardiac surgery and then compared the PCI results in the pilot hospitals with results in 120 non-pilot hospitals. The pilot program qualification incorporated appropriate planning and rigorous hospital, operator, patient, and lesion selection criteria.
- Trial objective: To test the hypothesis that remote per-postconditioning in connection with primary PCI will reduce myocardial infarct size patients with STEMI. - Trial Design: Placebo controlled randomized study with parallel groups - Primary Endpoint: Myocardial infarct size expressed as a percentage of the myocardium at risk determined by Cardiac Magnetic Resonance (CMR) day 4-7 - Efficacy Parameters: Myocardial infarct size expressed as a percentage to the myocardium at risk determined by CMR at 6 months. - Global left ventricular function determined by left ventricular ejection fraction determined by CMR. - Microvascular obstruction determined by CMR day 4-7. Quantified ECV (extracellular volume) in left ventricular as myocardium at risk day 4-7 and remodelling parameters day 180. - Safety Parameters: Major adverse cardiovascular events.
