AIM III is a prospective, randomized, double-blinded, placebo controlled trial. The study is directly connected to IRB 08-008161 as a specific aim of the NIH grant. Participants must consent to and qualify for AIM I and AIM II (IRB 08-008161) to be considered for this study.
The main goal of AIM III is to assess and quantify the effect of long-term administration of darapladib 160 mg once a day, a selective, reversible, orally active inhibitor of plasma and vascular Lp-PLA2, on coronary endothelial function, progression of coronary atherosclerosis as determined by IVUS, and atherosclerosis in patients with early atherosclerosis. Patients with evidence of coronary endothelial dysfunction, as determined by intracoronary administration of acetylcholine during angiography and IVUS, will be followed for 6 months during once daily dosing of darapladib. Coronary endothelial function is determined by the changes in coronary artery diameter and coronary blood flow response to the intracoronary administration of acetylcholine and adenosine. The patients will be followed in clinic at 3 months and 6 months. They will have follow-up angiography, assessment of endothelial function, and IVUS with VH during the six month visit.

This study will test whether darapladib can safely lower the chances of having a cardiovascular event (such as a heart attack or stroke) when treatment is started within 30 days after an a...
This study will test whether darapladib can safely lower the chances of having a cardiovascular event (such as a heart attack or stroke) in people with coronary heart disease.
Peripheral and coronary endothelial dysfunction in type 2 diabetic patients may be influenced by therapeutics. Using Radial flow monitoring and myocardial perfusion magnetic resonance imag...
The purpose of this study is to examine the hypothesis that the presence of complex coronary lesions is associated with endothelial dysfunction, the investigators investigated whether fing...
Coronary Artery Disease (CAD) is common in Mexico, while morbidity and mortality is high. Drug therapy can relieve angina pain and stabilize plaque, but it is not able to re-flow a coronar...
Lipoprotein-associated phospholipase A2 (Lp-PLA2), a novel biomarker for vascular inflammation, is associated with coronary endothelial dysfunction (CED) and independently predicts cardiovascular even...
The xanthine oxidase (XO) system is a significant source of vascular oxidative stress, which is believed to impair endothelial function, an important contributor to atherosclerotic disease. We tested ...
The role of serum uric acid in coronary artery disease has been extensively investigated. It was suggested that serum uric acid level (SUA) is an independent predictor of endothelial dysfunction and r...
We evaluated the effect of chronic exposure to air pollutants (APs) on coronary endothelial function and significant coronary artery spasm (CAS) as assessed by intracoronary acetylcholine (ACH) provoc...
Endothelial cell dysfunction in diabetes is involved in the pathogenesis and progression of premature atherosclerosis. High-dextrose has been shown to induce both oxidative stress and endoplasmic reti...
Abnormal balloon- or sac-like dilatation in the wall of CORONARY VESSELS. Most coronary aneurysms are due to CORONARY ATHEROSCLEROSIS, and the rest are due to inflammatory diseases, such as KAWASAKI DISEASE.
Malformations of CORONARY VESSELS, either arteries or veins. Included are anomalous origins of coronary arteries; ARTERIOVENOUS FISTULA; CORONARY ANEURYSM; MYOCARDIAL BRIDGING; and others.
Complete blockage of blood flow through one of the CORONARY ARTERIES, usually from CORONARY ATHEROSCLEROSIS.
Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery.
Surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion.
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
