Filter by:Numerous single-center studies have indicated gadolinium-enhanced stress CMR perfusion imaging has excellent diagnostic accuracy for coronary artery disease and negative clinical event rates, with its diagnostic accuracy exceeding nuclear scintigraphy. However, current prognostic evidence supporting clinical use of stress CMR is limited by study size, single-center settings with a predominance of academic centers, and a lack of "real-world" study design. Large-scale multicenter real-world evidence from a registry will provide the much needed information to guide evidence-based clinical adaptation that benefits patient care.
The purpose of the this trial is to evaluate the clinical safety and efficacy of Cilostazol eluting stent system (CES-1) for the treatment of single de novo lesions in native coronary arteries.
To determine whether, in a population of patients presenting to the rapid access chest pain clinic (RACPC), routine FFRct (Fractional Flow Reserve Computed Tomography) as a default test is superior in terms of resource utilisation when compared to routine clinical pathway algorithms recommended by the National Institute for Health and Care Excellence (NICE)
Cardiac ischemia is a common pathological condition, known to elicit multiple pathological processes at the cellular level. One of the most affected is thought to be cellular metabolism, key for the adequate cardiac function. The aim is to study mitochondrial bioenergetic function, interaction with other cellular systems and influence of several co-morbidities in myocardium of the affected patients.
The purpose is to compare median two-year clinical outcome after OCT guided vs. standard guided revascularization of patients requiring complex bifurcation stent implantation
The primary objective of this trial is to compare the safety and efficacy of the SINOMED BuMA Supreme biodegradable coronary stent in patients with up to 3 coronary lesions to either the XIENCE or Promus durable polymer coronary stents. This prospective, global, multi-center, randomized 2:1, single blind study will enroll up to 1632 subjects at up to 130 investigational sites in North America, Japan, and Europe. Subjects will have clinical follow-up in-hospital and at 30 days, 6 months, 12 months, and 2, 3, 4, and 5 years.
This study is undertaken to determine if intravenous Lipo-PGE1 therapy would improve coronary microvascular perfusion in patients with ischemic heart disease by CMRI.
The OPTICO-ACS- study program - combining for the first time in vivo characterization of the ACS-causing "culprit lesion" by intracoronary imaging technique with optical coherence tomography (OCT) and molecular analysis of immune-cells derived from the culprit coronary thrombus and biochemical analyses in patients with acute-coronary-syndrome (ACS).
This study evaluates the short-term patency of vein graft harvested by the No-Touch technique compared to that by the conventional approach in patients undergoing isolated on-pump/off-pump coronary artery bypass graft (CABG) surgery. a total of at least 2000 patients undergoing isolated on-pump/off-pump CABG will be consecutively recruited from 7 hospitals across China and randomly assigned to receive No-Touch saphenous vein harvesting or conventional approach. All participants will be invited for clinical follow-up and 64-slice multislice computed tomography angiography (MSCTA) analysis at 3 months post-operatively.
This trial will evaluate Orbital Atherectomy compared to conventional balloon angioplasty technique for the treatment of severely calcified lesions prior to implantation of drug-eluting stents (DES).
