Filter by:This is a multi-center, randomized, double-blind, triple-dummy, parallel-controled, dose-exploration phase II trial. Patients with coronary atherosclerotic heart disease and planned percutaneous coronary intervention （PCI） will be randomized after informed consent, in a 1:1:1:1 ratio to the following treatment groups: Experimental group 1 : Vicagrel 20mg loading followed by 5mg/day for 28 days; Experimental group 2 : Vicagrel 24mg loading followed by 6mg/day for 28 days; Experimental group 3 : Vicagrel 30mg loading followed by 7.5mg/day for 28 days; Control group : Clopidogrel 300mg loading followed by 75mg/day for 28 days. The primary purpose of this trial is to evaluate the efficacy, safety of vicagrel antiplatelet therapy and explore dose in patients with coronary atherosclerotic heart disease during and after PCI compared with clopidogrel.
The study design is a prospective, multicenter, single-arm, global IDE study to evaluate the safety and effectiveness of the Shockwave Medical Coronary Intravascular Lithotripsy (IVL) System in de novo, calcified, stenotic coronary arteries prior to stenting. Disrupt CAD III is being conducted as a staged pivotal study.
In-stent restenosis remains one of the most challenging problems in patients after coronary artery angioplasty. Angiographically, it is discovered in 10% of the patients after drug-eluting stent (DES) implantation. There are multiple factors causing restenosis, which can be divided into two major groups: first vessel-dependent (based on the vessel's tortuosity, dimensions and lesion's calcification, all leading to suboptimal stent expansion), and second dependent on the inflammatory processes caused by the intervention. Study objectives is the analysis of the possible correlation between allergy to metals utilised during the stent manufacturing (nickel, cobalt, chromium, molybdenum, tungsten) and in-stent restenosis occurence. The angiographic results of stent implantation, and in-stent restenosis will be assessed independently by two skilled interventional cardiologists, and in case of their discrepant opinions, the decision will be made on the basis of the third cardiologist. The tests will be applicated during the hospitalisation, then read after 48 hours and 72 hours, and subsequently interpreted by the skilled dermatologist, during the hospital stay or afterwards.
Post Market study of the Fantom Sirolimus-Eluting Bioresorbable Coronary Scaffold
CFR has been studied for few years using 82 Rubidium PET (positron emission tomography) /CT. CFR has shown to be correlated with cardiovascular events occurring in the 10 following years. CFR also helps to identify multivessel coronary disease. Few studies have shown the possibility to calculate CFR during myocardial perfusion SPECT on new ultrafast CZT cameras.
To observe the continued performance of the Medtronic Resolute Onyx™ Zotarolimus-Eluting Coronary Stent System in a real-world more-comer population. To collect data on the safety and efficacy of the Medtronic Resolute Onyx™ Zotarolimus-Eluting Coronary Stent System in bifurcated lesions.
The study will estimate the current status of participants with non-obstructive coronary artery disease confirmed via coronary angiography.
Patients who present to the emergency department (ED) with acute chest pain (ACP) possibly due to Coronary artery disease (CAD), with a normal heart tracing (ECG), need to have further troponin blood tests to confirm or exclude a heart attack. After initial troponin testing, a significant 50-85% of patients are said to be in an "observational zone" as one cannot confirm or exclude a diagnosis of a heart attack. Even after repeat blood testing, 22-33% remain in this "observational zone". These patients can be challenging to manage as they are not safe to be discharged home, but they also cannot be treated as a heart attack. This contributes to ED overcrowding and uncertainty in treatment plans.
This study evaluates coronary artery disease after heart transplantation and its relation to platelet function. Furthermore, we will evaluate extracorporeal photopheresis as treatment of coronary artery disease after heart transplantation.
Complete arterial coronary artery bypass grafting (CABG) is a surgical option to improve long-term results in the treatment of coronary artery disease (CAD). The goal of coronary artery bypass operations is complete revascularization and there is an increasing interest toward complete arterial revascularization to achieve this goal because of high late failure of saphenous vein graft
