NCT ID: NCT00431860 Recruiting - Clinical trials for Coronary Atherosclerosis

Subclinical COronary Atheroscleorosis Updated With Coronary cT Angiography (SCOUT Study)

Start date: December 2005
Phase: N/A
Study type: Observational

The purpose of this study is to validate the usefulness of 64-slice multi-detecter computeted tomography as a screening tool in asymptomatic population.

NCT ID: NCT00376870 Recruiting - Diabetes Clinical Trials

PIoglitazone for PrEvention of Restenosis in Diabetic Patients

Start date: July 2008
Phase: Phase 3
Study type: Interventional

Restenosis requiring reintervention is still a limitation of percutaneous coronary angioplasty. Despite the use of Drug eluting stent (DES), the rate of restenosis remains 7% to 16% in diabetic patients, making it a challenging problem in interventional cardiology. Still, in clinical trials, most of these attempts did not successfully limit neointimal formation after coronary stenting. Thiazolidinediones (TZDs), like pioglitazone (pio) or rosiglitazone, are a novel class of oral antidiabetic agents currently used to treat patients with type 2 diabetes mellitus. These agents increase insulin sensitivity and, as such, have favorable effects on blood glucose levels and the lipid profile in treated patients. Beyond their metabolic action, TZDs have been shown to exhibit antiinflammatory and antiatherogenic effects in vascular cells in vitro and to limit lesion development in various animal models of arteriosclerosis. Moreover, TZDs inhibit VSMC proliferation and migration, 2 critical processes in neointimal formation after coronary stenting. Data from rodent models suggest that TZDs limit intimal proliferation after vascular injury, and in clinical studies with type 2 diabetic coronary artery disease (CAD) patients, TZDs have been shown to reduce neointimal formation as well as restenosis after coronary stent implantation. Still, it remains unclear to what extend these effects depend on the metabolic action of these drugs and what might mainly be due to the improvement in glycemic control. Recently a few reports on prevention of restenosis in type 2 diabetic patients (T2DM) with the use of TZDs as been published. All of them uses BMS as endoprosthetic devices. None of these evaluated the use of TZDs in combination with DES. Aim of the study is to evaluate the efficacy of pioglitazone in prevention of in-stent restenosis after successful implantation of a sirolimus-eluting coronary stent for treatment of de-novo "complex" coronary vessel disease in patients with T2DM and stable coronary artery disease. Study primary end-point are late-loss at 9 months.Secondary end-point include binary restenosis MACE at 1, 9 and 12 month, stent thrombosis at 12 months.

NCT ID: NCT00155350 Recruiting - Inflammation Clinical Trials

Treatment of Coronary Atherosclerosis by Insulin Sensitizers in Insulin-Resistant Patients

Start date: November 2004
Phase: Phase 4
Study type: Interventional

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.
