Active clinical trials for "Coronary Disease"

Now, adipose tissue is established as an active endocrine organ that controls systemic energy homeostasis by secretion of adipokines. Recently, members of the C1q/tumor necrosis factor-related protein (CTRP) family have been reported to share structural homology with adiponectin. To date, 15 CTRP family members have been found that might play major roles in metabolism and inflammation. The investigators tried to clarify the relationship between CTRP family and coronary artery disease (CAD) in Korean men and women.

The purpose of this study is to explore the effect of 20mg high loading dose of rosuvastatin on recurrent events in patients with established DM who is admitted for an ACS.

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.

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.

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.

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.

Invasive coronary angiography is currently considered gold standard in the assessment of coronary artery disease although the method has limitations. Most importantly invasive angiography only depicts coronary anatomy without determining its physiological significance i.e the likelihood that the stenosis impedes oxygen delivery to the heart muscle. Fractional flow reserve (FFR) is a catheterization technique for assessing the physiological significance of a coronary artery lesion during invasive coronary angiography. Coronary computed tomographic angiography (CCTA) is a noninvasive imaging test that has become an alternative route to diagnosis for patients with suspected coronary artery disease. Computational fluid dynamics combined with anatomical models based on CCTA scans allows determination of coronary flow and pressure, and has emerged as a promising diagnostic modality called CT-FFR. In this Project New Mathematical algorithms are developed for computation of CT-FFR. The main objective of this study is to determine the diagnostic accuracy of CT-FFR values obtained by the new method compared with invasive coronary angiography with fractional flow reserve and state-of-the-art dobutamin stress echocardiography.

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.

The study aim is to assess polyethylene glycol (PEG) coated collagen patch (Hemopatch) on the quality of drainage after surgery, the length of hospital stay, the number of reoperations due to haemorrhage and treatment cost. The study will be conducted in 200 patients undergoing Coronary Artery Bypass Grafting (CABG) with the use of extracorporeal circulation and Internal mammary Artery (IMA) harvesting. Traditional method of haemostasis will be applied in 100 patients and Hemopatch will be additionally used in 100 subjects to prevent haemorrhage after IMA harvesting and sternum closure.

This is a randomized trial assessing the impact of allopurinol on endothelial function in optimally treated diabetic patients with coronary artery disease. After initial screening, subjects were randomized to receive either optimal medical therapy (OMT) + allopurinol or OMT alone for 8 weeks. The dose of allopurinol was 300 mg for 4 weeks and 600 mg for 4 weeks with a 4-weekly check on hematology and biochemistry
