Active clinical trials for "Coronary Artery Disease"

To evaluate two educational programs that promoted the role of pediatric practices in lowering LDL cholesterol levels in 4-10 year old hypercholesterolemic children through dietary modification.

The purpose of this study is to design and evaluate targeted implementation strategies to fully integrate the VHA clinical practice guidelines for ischemic heart disease into VHA clinical practice. Effectively implementing the guideline will enhance the quality, appropriateness, timeliness, and cost effectiveness of care delivered to veterans with ischemic heart disease.

Reflexology influences pain perception and pain-impulse transmission by releasing endorphins (12). Patients with a variety of medical illnesses can benefit from hand reflexology by lessening their physical and emotional discomfort (13, 14). Therefore, this study was done to investigate the power of hand reflexology in ameliorating anxiety, pain, and fatigue among patients undergoing coronary angiography

Studies were found that a significant relationship between the severe periodontitis and increased CAVI values. While the exact mechanisms linking periodontitis, type 2 diabetes, and cardiovascular disease are not yet fully understood, it is clear that these diseases are interconnected. There are limited data in the literature evaluating the risk of atherosclerosis in diabetic individuals with periodontal disease. In our survey, we hypothesised that severe periodontitis may be a risk factor for the development of subclinical atherosclerosis among people with type 2 diabetes. Thus, we aimed to investigate the potential risk of subclinical atherosclerosis by using a new surrogate marker CAVI in severe periodontitis patients with short-term diabetes.

We investigated in-vitro the management of intraprocedural anticoagulation in patients requiring immediate percutaneous coronary intervention(PCI) while using regular direct oral anticoagulants(DOACs). Twenty-five patients taking 20mg of rivaroxaban once daily comprised the study group, while five healthy volunteers included the control group. In study group, a beginning(24-hours after the last rivaroxaban dose) examination was performed. Then, the effects of basal and four different anticoagulant doses(50IU/kg unfractionated heparin(UFH), 100IU/kg UFH, 0.5mg/kg enoxaparin, and 1mg/kg enoxaparin) on coagulation parameters were investigated at the 4th and 12th hours following rivaroxaban intake. Anticoagulant activity was assessed mainly by anti-factor Xa(anti-Xa) levels.

This traditional feasibility study aims to capture preliminary safety and effectiveness information on a near-final Investigational Device design to adequately plan the forthcoming pivotal study.

Coronary atherosclerotic heart disease (CAD) has been considered the leading cause of death in both developed and developing countries. Coronary artery bypass grafting (CABG) is a major therapy of CAD in the world, mainly used for patients with left main disease, multi-vessel complex disease, stent implantation failure, heart failure and diabetes. Studies have demonstrated that significant angiographic defects up to 12% of grafts, which was observed by immediate coronary angiography after CABG. Despite secondary prevention were performed in patients after CABG, the early failure rate at 1 year is higher, up to 15-20%, the 10-year patency rate of internal mammary artery graft is 85%, and the 10-year patency rate of saphenous vein graft is only 61%, and 10-20% of patients require revascularization within 10 years after CABG. Patients with failed grafts usually have a higher surgical risk and the morality of repeat CABG is 2-4 times higher than primary surgery. Because of the poor clinical prognosis of patients undergoing repeat CABG, PCI is the preferred treatment strategy for revascularization in patients with previous CABG. In patients with previous CABG, approximately 75% of PCI target vessels are native vessels. Compared with native vessel PCI, bypass graft PCI has a higher rate of short- and long-term major adverse events, including more than double the in-hospital mortality rate. Some studies support the above view，but others denied. Therefore, the primary study mainly to explore the effect of native vessel PCI or graft PCI on the prognosis of patients with previous CABG.

Investigational, prospective, multi-site, first in human, feasibility evaluation

Coronary microvascular dysfunction (CMD) is increasingly recognized as an important indicator for long-term prognosis in patients with acute myocardial infarction (AMI). The angiography-derived index of microcirculatory resistance (angio-IMR) is a novel guidewire-free measure for CMD in patients with AMI. Ticagrelor has recently been suggested to have additional benefits on coronary microcirculation beyond its antiplatelet effect. This study was designed to compare the protective effects of ticagrelor and clopidogrel on CMD and prognostic impact in patients with AMI, using the angio-IMR as a novel assessment tool.

The left distal radial approach (DRA) has been introduced as a feasible and safe alternative route of the radial artery. However, there is still lack of evidence for DRA regarding the feasibility, safety, effective time for hemostasis and hemostasis method. This prospective multicenter registry aimed to investigate the safety and efficacy of DRA for CAG and PCI.
