Filter by:Arterial access is the key step during the endovascular treatment of cardiovascular diseases. This study was designed to confirm the safety and efficacy of the hemostasis pad using chitosan in patients undergoing percutaneous procedures with arterial approach. Two cohorts will be included in this study: transradial and transfemoral cohort. Among the transfemoral cohort, the safety and efficacy of the ezClot pad will be compared with the BloodSTOP® pad (LifeScience PLUS, Palo Alto, CA, USA). The BloodSTOP® pad is an etherized and oxidized regenerated cellulose matrix that achieves hemostasis by activating the intrinsic coagulation pathway. The hypothesis will be tested among the transradial cohort that the combined use of a hemostasis pad and a compression device is superior to that of a compression device only in terms of hemostasis in patients who underwent tranradial coronary procedures.
evaluate the safety of preoperative aspirin therapy when performing bypass surgery in conditions of artificial blood circulation
The primary goal of this study is to determine the prevalence of undiagnosed asymptomatic coronary artery disease (CAD) in Kalamazoo and its neighboring areas using Coronary Computed Tomography (CCTA) and Coronary Artery Calcium Score (CACS) to assess if asymptomatic CAD is widespread enough to warrant implementation of CCTA as a routine screening tool. Additionally, this study will use the CCTA results to evaluate several methods of assessing CAD risk in the asymptomatic population including Framingham Risk Score (FRS) and Reynold's Risk Score, Biomarkers (High sensitivity C-Reactive Protein, Fibrinogen, Vertical Auto Profile, oxidized Low Density Lipoprotein (LDL), Apolipoprotein A1 (ApoA1), Apolipoprotein B1 (ApoB1), Vitamin D, Homocysteine) as well as a large panel of genetic markers of atherosclerosis and dyslipidemia.
Percutaneous Coronary Intervention (PCI) is increasingly effective to treat Chronic Total Occlusion (CTO) lesions in coronary arteries. This trial will examine modern dissection and re-entry approaches to treat more complex CTO lesions with the Absorb Bioresorbable Vascular Scaffold (BVS).
The study aims to evaluate the safety and efficacy of polymer-free sirolimus-eluting coronary stent system (NANO plus) in patients with coronary artery disease . The primary endpoint is target lesion failure, a composite endpoint of cardiac death, target vessel related myocardial infarction and clinically-driven target lesion revascularization at 1 year follow-up.
The purpose of this study is to evaluate the safety and performance of a new version of a coronary artery stent for treating blockages in the arteries supplying blood to the heart muscle. The Amaranth Medical MAGNITUDE scaffold releases a drug (sirolimus) to reduce the likelihood of the treated blood vessel developing a new blockage. In addition, the scaffold dissolves away over time, leaving no permanent implant after the blood vessel has healed.
The purpose of this study is to evaluate the radiation exposure in patients undergoing coronary angiography, and to identify reference values for the main radiation doses parameters.
Ticagrelor is an oral, reversibly-binding, direct-acting P2Y12 receptor antagonist used clinically for the prevention of atherothrombotic events in patients with acute coronary syndromes (ACS). 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. However, few East Asian patients have been included in these trials to assess the use of these drugs. In addition, a growing body of data supported that East Asian might have different adverse event profiles (thrombophilia and bleeding) and "therapeutic window" compared with white subjects. But it is still not clear whether a low dose of ticagrelor is superior to clopidogrel in diabetic patients with stable coronary disease. Recent studies found that antiplatelet drugs might have anti-inflammatory effects and protect endothelial function. ACS patients treated by ticagrelor had a significantly higher increase in levels of circulating progenitor cells compared to those treated by clopidogrel, suggesting a benefit on endothelial regeneration that may participate in the pleiotropic property of the drug. This may prompt the regression of blood vessels and the endothelium stability. But it is not very clear that the effect of low-dose ticagrelor on vascular endothelial function in diabetic patients with stable coronary artery disease. Therefore, the investigators performed this randomized, single-blind clinical trial to observe the effects of different doses of ticagrelor and standard-dose clopidogrel on platelet aggregation and endothelial function in diabetic patients with stable coronary artery disease.
Schizophrenia is a severe mental illness associated with excess mortality and affecting nearly 1% of the population. The average life expectancy for patients diagnosed with schizophrenia has been 55-60 years through the last generations in Denmark, while the general population has over the same period of time experienced an increase in life expectancy. As a result, the standardized mortality rate for patients with schizophrenia has increased markedly over the last three decades and is currently a major public health concern. Causes of death are mainly cardiovascular disease and patients diagnosed with schizophrenia has a relative risk of cardiovascular disease that is about 2-fold higher than the general population.
This study is a prospective, randomized, open-label, single-center trial designed to compare the 30 month-safety and efficacy between low-dose (5mg/dL) and high-dose (20mg/dL) rosuvastatin treatment for patients with coronary artery disease after percutaneous coronary intervention with the newer drug-eluting stent.
