Filter by:• The aim of the VIP study is to investigate the impact of vulnerability markers (inflammatory serum biomarkers for systemic vulnerability, coronary shear stress and vulnerability mapping for pancoronary vulnerability, and imaging-based plaque features for systemic vulnerability) on the rate of major adverse cardiovascular events caused by progression of the non-culprit lesion in patients with acute ST or non-ST segment elevation myocardial infarction who undergo revascularization of the culprit lesion during the acute event. Furthermore, the study will evaluate the rate of progression of non-culprit lesions towards a higher degree of vulnerability, based on coronary computed tomography angiographic assessment at 1 year after enrollment.
This study will look at performing a prophylactic limited left sided maze procedure during concomitant adult cardiac surgery to prevent the common occurrence of postoperative atrial fibrillation.
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.
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.
The study is to further exploring the optimal switching strategy by evaluating the pharmacodynamic responses as well as adverse events in patients with complexity of coronary artery disease managed by percutaneous coronary intervention (PCI). All participants will be divided into three groups and recieving ticagrelor 90mg plus aspirin 100mg at 12 hours after the last dose of clopidogrel; recieving ticagrelor 90mg plus aspirin 100mg at 24 hours after the last dose of clopidogrel; recieving ticagrelor 180mg plus aspirin 100mg at 24 hours after the last dose of clopidogrel.
Background: the decision-making process of patients with angiographically-intermediate coronary lesions (ICL) is clinically challenging and may benefit from adjunctive invasive techniques. Fractional-flow-reserve (FFR) represents the gold standard to evaluate ICL but optical-coherence-tomography (OCT) is a novel, promising, high resolution coronary imaging technique. Objectives: 1. Investigate the relation between OCT and FFR parameters in ICL and understand if OCT measures may predict FFR. 2. Understand if OCT parameters may predict clinical outcome of patients with ICL not underwent revascularization on the bases of negative FFR. Study design: multicentre, international, individual patient's level data pooled analysis.
Bioresorbable vascular scaffolds (BVS) are considered as a new revolution in coronary intervention due to their potential advantages for long term follow up. However, current generation BVS have also some drawbacks that restrict the use for complex lesions. Using BVS and drug eluting stents (DES) together -implanting DES for BVS inappropriate segments -may be a feasible option to avoid the disadvantages of permanent foreign body and to reduce very late adverse events. In this context, we investigated the clinical outcomes following treatment with hybrid strategy with concomitant use of BVS and DES for complex lesions. A single center retrospective cohort was performed enrolling 40 patients with complex lesions treated with hybrid approach from February 2015 up to April 2017. Lesion segments with a large plaque burden and/or severe calcification, aorto-ostial and bifurcation lesions that may be unfavorable for BVS, treated with DES. BVS and DES were implanted with minimal overlap of DES and BVS struts. The primary end-point was target lesion failure (TLF) which was a composite of cardiac death, target vessel myocardial infarction and target lesion revascularization (TLR). During follow-up, coronary angiography was performed when patients had ischemic symptoms.
