Active clinical trials for "Myocardial Ischemia"

This is a prospective, multi-center, open label, randomized study to evaluate the efficacy and safety of The TIVOLI Biodegradable polymer Rapamycin-Eluting Stent comparing with The FIREBIRD2™ Rapamycin-eluting Stent (DES) for Treatment Coronary Revascularization.

Patients with ischemic heart disease often report multiple symptoms, including angina and palpitations. Ranolazine has antiarrhythmic effects which are largely a result of the drug's effect on multiple ion channels. It remains unknown, however, whether the favorable effects of ranolazine on symptoms and arrhythmias are maintained over time. Aim of this study is to test the hypothesis that chronic treatment with ranolazine can improve the symptomatic status of patients with ischemic heart disease by reducing the occurrence of palpitations.

Aims and Hypotheses: This randomised placebo controlled study will test the hypothesis that Recombinant Activated Factor VII (rVIIa) will improve haemostasis after an inadequate response to conventional therapy in complex cardiac surgery. Major bleeding is still of concern in complex cardiac surgery. It has been shown to be associated with poorer patient outcome and results in the consumption of resources (hospital costs, manpower and blood bank reserves). This study has the potential to provide evidence that rVIIa can reduce transfusion requirements and improve patient outcome in a problematic aspect of complicated cardiac surgery. The objective is to conduct a multi-centre randomised placebo controlled study that has been designed to scientifically evaluate the treatment of post bypass coagulopathy in the association with complex cardiac surgery. The trial design is based on clinical practice that has evolved over 2 years at the Austin Hospital during which 38 patients have received open label administration of rVIIa. There is currently no published RCT in this area and there is no TGA approval for the use of rVIIa for this indication.

In this study, we, the investigators at National Taiwan University Hospital, will evaluate the efficacy of pharmacological therapy targeted to reduce insulin resistance (pioglitazone) on the progression and compositional change of non-obstructive coronary atherosclerotic plaques and coronary calcification by serial intravascular ultrasound (IVUS)/multi-detector-row computed tomography (MDCT) follow-up in patients with type 2 diabetes or non-diabetic metabolic syndrome during a 2-year period.

There is a remarkable lack of randomized trials concerning the potential benefit of using arterial conduits for coronary bypass surgery. This is the purpose of the present trial. Exclusive use of arterial conduits might result in improved conduit viability, reduced risk of recurrent angina, myocardial infarction and other cardiac events, reduced need for antianginal medication, improved functional status and possibly improved long term survival. The patients will be followed for ten years after surgery.

The aim of the study is to determine, wheather strict dietary intervention with the use of the DASH diet atop of optimal medical treatment reduces previously diagnosed coronary atherosclerotic lesions assessed witch coronary computed tomography.

This study evaluated epidemiology and clinical outcome of clopidogrel related various genotyping in Korean patients who had undergone percutaneous coronary intervention as a all comer registry form.

In human purified platelets, only thrombin, and not the other platelet agonists, leads to a transient activation of the protein kinase activated by AMP (AMPK) and to phosphorylation of its "bona fide" substrate, ACC on its Ser79. ACC phosphorylation (P-ACC) can be an interesting marker of thrombin action on platelets. Indeed platelet and coagulation interplay, though undoubtedly present in atherosclerosis and atherothrombosis, remains difficult to assess. Our group showed that atherosclerotic mice (SRBI/Apolipoprotein E knock-out) had higher platelet P-ACC compared to corresponding control mice (C57BL6). In agreement with these data, preliminary results showed increased platelet P-ACC in a small cohort of patients admitted for coronary angiogram, with demonstrated coronary artery disease (CAD). In the light of our preliminary results, we sought to analyze platelet P-ACC in a large prospective clinical trial (ACCTHEROMA) in patients admitted for coronary angiogram. The aim of the study is to compare platelet P-ACC in platelets of patients with CAD and more particularly in unstable CAD patients to non-CAD patients. This study could potentially identify patients at high risk of future ischemic cardiovascular events, because of a higher level of thrombin generation.

Laugh is more than visual and vocal behave, is always followed by a series of physiological changes, including contractions of musculoskeletal system, increase of cardiac frequency by catecholamine release and hyperventilation that promoves the increase of maximum breathing and oxygen saturation. Laugh therapy may be an alternative therapy, simple, and improve the quality of life of individuals can influence physiological and biochemical parameters of the human body.

This is a Phase 3, prospective, open-label, international, multicentre study of Flurpiridaz (18F) Injection for PET MPI in patients referred for ICA because of suspected CAD.
