Efficacy and Safety of Low-dose Ticagrelor

Coronary Artery Disease

Guideline recommendations on the use of dual antiplatelet therapy have been formulated that ticagrelor 90 mg twice daily plus aspirin in preference to clopidogrel 75mg daily plus aspirin for ACS patients. Recent study found that ticagrelor 90mg twice a day orally could significantly reduce the occurrence of clopidogrel resistance and adverse cardiovascular events. The previous studies have reported that half-dose ticagrelor had the similar inhibitory effect on platelet aggregation as the standard-dose ticagrelor, which was significantly stronger than that in the clopidogrel group. One-quarter standard-dose ticagrelor provided greater degree of platelet inhibition than standard dose clopidogrel in Chinese patients with stable CAD. But large-scale clinical trials are still needed to confirm the effects of low-dose ticagrelor on platelet function in Chinese patients with coronary heart disease.

The XIENCE 28 USA Study is prospective, single arm, multi-center, open label, non-randomized trial to evaluate safety of 1-month (as short as 28 days) dual antiplatelet therapy (DAPT) in subjects at high risk of bleeding (HBR) undergoing percutaneous coronary intervention (PCI) with the approved XIENCE family (XIENCE Xpedition Everolimus Eluting Coronary Stent System [EECSS], XIENCE Alpine EECSS and XIENCE Sierra EECSS) of coronary drug-eluting stents.

Efficacy and Safety Study of Ezetimibe (SCH 58235, MK-0653) in Addition to Atorvastatin in Participants...

Hypercholesterolemia

The overall objective is to evaluate the efficacy and safety of ezetimibe (SCH 058235/MK-0653) 10 mg administered daily in conjunction with atorvastatin in participants with Heterozygous Familial Hypercholesterolemia (HeFH) or in participants with coronary heart disease (CHD) or multiple cardiovascular risk factors (≥2 risk factors) and primary hypercholesterolemia not controlled by a starting dose (10 mg/day) of atorvastatin. The primary hypothesis is that the coadministration of ezetimibe 10 mg/day with atorvastatin therapy will result in a significantly greater proportion of participants achieving target low-density lipoprotein cholesterol (LDL-C) (≤100 mg/dL) when compared to the atorvastatin administered alone.

Effects of Statin for Elderly Patients With Atherosclerotic Cardiovascular Disease

AtherosclerosesCoronary

High-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.

The Effects of Obstructive Sleep Apnea and Its Intervention on Coronary Heart Disease

HypertensionMetabolic Disorder

Obstructive sleep apnea(OSA) is an important identifiable cause of hypertension. Previous study has suggested that OSA significantly increases cardiovascular morbidity and mortality, especially in patients with pre-existing cardiovascular disease.The standardized treatment of moderate/severe OSA is continuous positive airway pressure (CPAP). Most of short-term trials indicated that CPAP treatment reduced BP in patients with OSA. But relevant studies have a relative short duration with only but few more than one year. In our opinion, they are not sufficient to detect the real effect of CPAP on reduction in BP. Besides, the impact of OSA on metabolic disorder is still unclear.We hypothesized that long-term CPAP treatment could reduce blood pressure and improve metabolic disorder in patients with coronary heart disease (CHD)and OSA.

Absorb IV Randomized Controlled Trial

Coronary Artery DiseaseCoronary Artery Stenosis2 more

ABSORB IV is a prospective, randomized (1:1, Absorb BVS to XIENCE), single-blind, multi-center study, registering approximately 2610 subjects from approximately 140 sites in the United States and outside the United States. ABSORB IV is a continuation of ABSORB III (NCT01751906) trial which are maintained under one protocol because both trial designs are related. The data from ABSORB III and ABSORB IV will be pooled to support the ABSORB IV primary endpoint. Both the trials will evaluate the safety and effectiveness of Absorb BVS. The ABSORB IV Randomized Controlled Trial (RCT) is designed to continue to evaluate the safety and effectiveness as well as the potential short and long-term benefits of Abbott Vascular Absorb™ Bioresorbable Vascular Scaffold (BVS) System, and the Absorb GT1™ BVS System (once commercially available), as compared to the commercially approved, control stent XIENCE.
