Study title:A Study for Testing Safety and Efficacy of the administration of Blood-Borne Autologous Endothelial Progenitor Cells to Alleviate Anginal Symptoms and Myocardial Ischemia in Patients with Severe Anginal Syndrome Principle Investigator: Assoc. Prof. Damras,Tresukosol,M.D.,Head of Cardiac Catherlization unit,Division of Cardiology,Department of Medicine,Faculty of Medicine Siriraj Hospital,Mahidol University Study objective : To determine the safety and efficacy of intracoronary injection of blood-borne autologous EPCs in relieving symptoms of angina pectoris in symptomatic patients treated with maximal medical therapy with an occluded coronary artery supplying ischemic myocardium Study Design : Phase II, a single center,a non-randomized,open-label trial, Study population : Total expected no. of patients : 24 main selection criteria : - Patients with chronic stable angina on maximal medical therapy and an occluded coronary artery supplying an ischemic viable myocardial region as shown on Sesta-mibi scan. On coronary angiography,the occluded coronary artery must have a patent proximal segment of at least 30 mm with at least one side branch to enable the injection of the EPC if the vessel remains occluded despite the attempted angioplasty efforts. - Age 18-80 years - Ejection fraction >35 % on Sesta-mibi scan - Sestamibi scan (myocardial perfusion) during exercise or dipyridamole,demonstrating regional reversible ischemia in an area relating to the occluded coronary artery. Investigational Product : At D-8 250 ml of blood drawn from the patients for production of autologous EPCs or ACPs (VescellTM), On D0 ,at least 1.5 million EPCs with viability >75 % suspended in 6 ml sterile cell culture medium will be injected to the same patients by intracoronary artery. The study consists of 4 periods:Screening ( D-14to-9&D-8,Treatment(D0),Acute Safety follow-up (D1&D2),Chronic follow-up (D30,D90&D180)period ,total follow-up of each case is 6 months. Evaluation criteria : Safety : no.& duration of adverse event & serious adverse event Efficacy : - change from baseline to 1,3,6 months of CCS, 6-minute walking test - change from baseline to 3 & 6 months of Sesta-mibi scan - change from baseline to 3 & 6 months of symptom-limited exercise time,exercise-induced ischemia & METs on Sesta-mibi scan Duration of study: July 2004-December 2006

NCT ID: NCT00375336 Active, not recruiting - Aortic Stenosis Clinical Trials

Risk Factors Associated With Calcification of the Aortic Valve

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

The purpose of this study is - to determine the degree of endothelial dysfunction and inflammation in calcific aortic valve disease associated with coronary artery disease(CAD). - to determine whether there is relationship between calcium metabolism and calcific aortic valve disease associated with CAD.

NCT ID: NCT00364390 Active, not recruiting - Clinical trials for Coronary Artery Disease

A Study of Anginera In Patients Undergoing Coronary Artery Bypass Graft (CABG) Surgery

Start date: April 2006
Phase: Phase 1
Study type: Interventional

This is a first in man, Phase I safety study of Anginera in adults with Left Ventricular Dysfunction (LVD) and Reversible Myocardial Ischemia undergoing a CABG procedure.

NCT ID: NCT00290056 Active, not recruiting - Clinical trials for Coronary Artery Disease

Effect of Supplemental Intake of Omega-3 Polyunsaturated Fatty Acids on the Rate and Complexity of Spontaneously Occurring Ventricular and Supraventricular Arrhythmias in Patients With Implantable Cardioverter Defibrillator (ICD) - A Randomized Clinical Trial

Start date: November 2005
Phase: Phase 4
Study type: Interventional

We hypothesize that oral supplementation with omega-3 PUFA will decrease occurrence of arrhythmic events among post-MI, ICD recipients.

NCT ID: NCT00238004 Active, not recruiting - Clinical trials for Coronary Arteriosclerosis

The Low HDL On Six Weeks Statin Therapy (LOW) Study

Start date: November 2005
Phase: Phase 4
Study type: Interventional

Abnormal blood cholesterol levels increase the risk of developing, or dying from heart disease. It is well recognised that if "harmful" LDL cholesterol is high, and "protective" HDL cholesterol is low, this risk is increased. Drugs called statins are routinely used in patients with heart disease, are well tolerated, and decrease the harmful LDL cholesterol levels. However, statins only increase protective HDL cholesterol to a small extent. Some patients may thus benefit from additional medication to increase protective HDL-cholesterol further. One of the most effective drugs which can do this is nicotinic acid. This drug is well established having been available for over 30 years. Previous use has been limited by facial flushing in a large percentage of patients receiving the drug. However a new formulation called Niaspan is now available which is associated with much less flushing. Although many patients will have transient flushing, it is estimated that only 1 patient out of every 20 receiving the drug will have to discontinue treatment. We therefore propose, in patients with coronary artery disease and low HDL cholesterol despite being on a statin, to study the effect of Niaspan on HDL cholesterol and other lipid parameters, and to assess its tolerability.

NCT ID: NCT00220558 Active, not recruiting - Clinical trials for Coronary Artery Disease

GISSOC II: Sirolimus Eluting Stent Versus Bare Metal Stent in Chronic Total Coronary Occlusions

Start date: May 2005
Phase: Phase 4
Study type: Interventional

The objective of this study is to compare the Cypher Select-TM Sirolimus Eluting Stent (SES) with the SONIC-TM Bare Metal Stent (BMS) in the treatment of Chronic Total Occlusion lesions (CTO). The primary hypothesis is that, at 8-month follow-up, the minimal luminal diameter (MLD) of the coronary segment treated with stent implantation in CTO lesions is significantly larger with the use of SES compared to BMS. The treated segment is defined as the segment covered by the stent(s) plus 5 mm proximally and distally to the stent(s).

NCT ID: NCT00192868 Active, not recruiting - Clinical trials for Coronary Artery Disease

Drug Elution and Distal Protection During Percutaneous Coronary Intervention in ST Elevation Myocardial Infarction

Start date: May 2005
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate the clinical, echocardiographic and angiographic outcome of distal protection in the infarct related coronary artery and implantation of drug eluting versus bare metal stents in patients with ST-elevation myocardial infarctions treated acutely with percutaneous coronary intervention.

NCT ID: NCT00159991 Active, not recruiting - Clinical trials for Ischemic Heart Disease

Copenhagen Arterial Revascularization Randomized Patency and Outcome Trial

CARRPO
Start date: February 2002
Phase: Phase 3
Study type: Interventional

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.

NCT ID: NCT00149591 Active, not recruiting - Clinical trials for Coronary Artery Disease

The Viability-Guided Angioplasty After Acute Myocardial Infarction-Trial (The VIAMI-Trial)

Start date: April 2001
Phase: N/A
Study type: Interventional

The VIAMI-trial investigates the effects of balloon angioplasty with stenting of the infarct-vessel in the early phase after acute myocardial infarction. The study concerns patients who have residual viable tissue in the infarct-area after being treated with thrombolysis. It is postulated that only patients with remaining viable tissue are at high-risk for recurrent infarction or anginal attacks and that stenting of the infarct-vessel will reduce this risk considerably.
