Saphenous Vein Graft AtherosclerosisThis is a phase IV, multi-center, double-blind, randomized, placebo- controlled study evaluating the effect of alirocumab on SVG atherosclerotic disease burden, as assessed by IVUS at baseline and following 78 weeks of treatment in subjects with at least one intermediate SVG lesion receiving optimal statin therapy.

Effects of Statin for Elderly Patients With Atherosclerotic Cardiovascular Disease
AtherosclerosesCoronaryHigh-dose statins can reduce mortality and cardiovascular events in patients with established atherosclerotic cardiovascular disease (ASCVD). Therefore, US and European recommendations recommend that established ASCVD patients (coronary artery disease, cerebrovascular disease, peripheral vascular disease) use high-dose statins to lower LDL cholesterol levels by at least 50%. However, in actual practice, high-dose statins are relatively less used, and the reason is unclear, but it is believed to be due to concerns about the side effects of high-dose statins. Most of the side effects of statins are statin-associated muscle symptoms (SAMS), which are more common than the incidence in clinical studies, especially in frontline care. These muscle side effects are dose-dependent and are common at high doses, and the incidence is known to increase in the elderly over 70 years of age. However, the US recommendation recommends using high-dose statins to lower LDL cholesterol by 50% or more to prevent cardiovascular events even in ASCVD patients over 70 years of age. Most early studies on lowering LDL cholesterol in ASCVD patients used high doses of statins. However, after introducing cholesterol absorption inhibitors ezetimibe and PCSK9 inhibitor, large-scale clinical studies have been conducted to lower LDL cholesterol using these drugs. In this study, as in the statin study, cardiovascular events were significantly reduced, and together with statins, it became a standard treatment for ASCVD patients. On the other hand, the clinical benefit shown in clinical studies using cholesterol-lowering agents so far depends entirely on how much LDL cholesterol is lowered and how long it is maintained in a low state, indicating that LDL cholesterol management is the core of arteriosclerosis treatment. In addition to high-dose statins, a combination of low-dose statins and ezetimibe can be cited as a method for lowering LDL cholesterol to more than 50%. In the latter case, it is expected that there will be an advantage of reducing muscle side effects by reaching the target LDL cholesterol level by using a low-dose statin. However, no studies compare the difference in muscle side effects between low-dose statins and ezetimibe combination drugs, which reduce LDL cholesterol to the same extent compared to high-dose statins, in elderly patients over 70 years of age with ASCVD. In this study, the association of low-dose rosuvastatin 5mg and ezetimibe combination (rosuvastatin 10/5mg) compared to high-dose rosuvastatin 20mg in elderly patients 70 years of age or older with established ASCVD. This study aims to compare and analyze the incidence of muscle symptoms (SAMS) and their effect on LDL cholesterol.
Darapladib China PK
AtherosclerosisThis study is to evaluate pharmacokinetics (PK), pharmacodynamics (PD) and safety of 160 mg enteric-coated micronised free base darapladib in healthy Chinese subjects.
Zinc and Selenium Supplementation in Atherosclerosis
Dietary Selenium DeficiencyDietary Zinc DeficiencyThe aim of this randomized double-blind study was to evaluate the effect of oral zinc and selenium supplementation on oxidative stress and inflammation biomarkers as well as the status of zinc and selenium in patients with atherosclerosis and angina stable treated with rosuvastatin. The hypotheses tested in this study were: Treatment with rosuvastatin impairs zinc and selenium status in patients with atherosclerosis and stable angina? Zinc and selenium supplementation, concomitantly with rosuvastatin, influences the antioxidant and anti-inflammatory as well as the status of minerals?
A Study to Assess the Effect of SB 659032 on Platelet Function
AtherosclerosisThis will be an open-label, single dose, single period study. Approximately 14 subjects will receive one dose of 250 mg of non-enteric coated SB-659032 following a low-fat breakfast. This study will evaluate whether SB-659032 has an effect on platelet function as determined by platelet aggregation tests using the agonists ADP and collagen. Blood samples for PK analysis and measurement of Lp-PLA2 activity will also be collected

Comparison of Agent™ and SeQuent® Please Paclitaxel Coated Balloon Catheters in Coronary In-stent...
Coronary Artery DiseaseCoronary Restenosis2 moreThe primary objective of this study is determine the safety and performance of the Agent™ Paclitaxel-Coated PTCA Balloon Catheter compared to the SeQuent® Please Paclitaxel-Releasing Coronary Balloon Catheter for the treatment of patients with narrowed previously-stented coronary arteries (in-stent restenosis). The performance will be determined at six months post-procedure by quantitative coronary angiography (QCA) to measure Late Lumen Loss (LLL) in the re-opened stented segment. QCA results will be assessed by an independent, blinded angiographic core lab. Study statistical hypothesis: The loss of in-stent luminal diameter at six months after treatment of the restenosed stent with the Agent™ study device is not larger than the respective LLL after treatment with the SeQuent® Please control devices, i.e. study device is non-inferior to the control device with respect to LLL.
Evaluation of The Effects of Nebivolol in Comparison to Atenolol on Wall Shear Stress and Rupture...
AtherosclerosisEndothelial FunctionNebivolol is a novel blood pressure lowering drug with an additional effect on the inner lining of blood vessels to release a compound called nitric oxide that can relax blood vessels. Atenolol is a blood pressure reducing agent without the ability to release nitric oxide and effect additional blood vessel relaxation. The goal of this proposal is to compare Nebivolol and Atenolol with respect to the following parameters: Plaque within arteries supplying the heart in terms of its volume and composition as assessed by ultrasound within these arteries. Ability of small arteries in the heart to open up and deliver an enhanced blood supply in response to drug called Adenosine (routinely used in the cardiac catheterization laboratory) as assessed by pressure and flow detecting catheters within these arteries. Ability of the inner lining of arteries that supply the heart to release a relaxing compound called nitric oxide in response to injection of Acetylcholine (also used in the cardiac catheterization laboratory) as assessed by squirting dye into these arteries Local forces that affect blood flow in the arteries supplying the heart as assessed by superimposing the above data into complex maps created offline at Georgia Institute of Technology. It is likely that Nebivolol causes the plaque within arteries supplying the heart to change from the 'vulnerable' type to the 'stable' type plaque. There are several features of "vulnerable plaques" that can be detected in arteries of the heart using intravascular ultrasound (a small ultrasound camera that goes in the arteries of the heart). The investigators hypothesis is that Nebivolol will prove superior to Atenolol in reducing 'vulnerable plaques', improve blood flow within the small arteries and the health of inner lining of these arteries at the 1 year time point. The investigators plan to enroll 20 patients into the study (26 patient including dropouts) who will be randomized in a 1:1 manner to Nebivolol Vs Atenolol for 1 year and repeat evaluation at that time point.
AFRICA: Atorvastatin Plus Fenofibric Acid (TriLipix) in the Reduction of Intermediate Coronary Atherosclerosis...
Coronary AtherosclerosisThis study will examine how an approved drug (TriLipix), when used in combination with a statin (a drug that lowers blood cholesterol levels), affects the makeup of plaque. Patients will be randomly assigned to receive either the study treatment (TriLipix plus Atorvastatin) or the comparison treatment (a placebo). Comparison of the effect on the makeup of plaque will be done by using coronary artery computed tomography angiography (CTA), which all participants will have at enrollment and at the end of the study (18 months after enrollment).
