Filter by:Modern high-end CT scanners with faster scan acquisition times now allow for routine assessment of cardiac pathologies, which could result in numerous incidental cardiac findings on standard thoracic CT angiography (CTA) scans. The CaPaCT-study aims to assesses the presence, management and possible clinical impact of incidental cardiac pathologies which are becoming visible on standard thoracic CT scans performed on new high-end scanners.
The purpose of this study is to determine if extra systoles can be used to predict fluid responsiveness perioperatively in patients undergoing on pump coronary artery bypass graft (CABG) surgery. As an additional study we will investigate the ability of a mini fluid challenge to predict response of a larger volume of fluid.
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.
HIV-infected patients with intermediate-high risk have a high prevalence of CAD and a substantial proportion of obstructive CAD. Degree of stenosis is associated with immunoactivation (lymphocyte and monocyte) and microbial translocation
Previous studies reported 20-30% of under-expansion or malapposition with BVS, which would increase the risk of adverse events including late stent thrombosis. OCT-guidance may improve more optimized scaffold placement and also better outcomes. However, there is still no sufficient evidence that OCT has an inevitable role in optimal implantation of BVS and it should be more evaluated in real practice. In the study, the investigators will evaluate an incidence of OCT-defined BVS sub-optimization requiring additional PCI+A1.
This prospective multicenter registry evaluates the efficacy of hybrid coronary revascularization (HCR) combining coronary artery bypass surgery (CABG) and percutaneous coronary intervention (PCI) in the treatment of multivessel coronary artery disease. CABG is to be performed in the left anterior descending artery and the left circumflex artery using only arterial grafts, whereas PCI is to be conducted for the treatment of significant stenotic disease in the right coronary artery with everolimus-eluting stents (EESs). This research plans to involve patients scheduled for coronary revascularization for multivessel coronary artery disease who consent to participate in the registry.
Published data indicate that obstructive sleep apnea syndrome (OSAS) worse the prognosis of coronary artery disease (CAD) and that oxidative stress can link this 2 diseases. Investigators hypothesise that oxidative stress decrease after 3 months of continuous positive airway pressure (CPAP) in this specific population. The results may have major implication in the comprehension of physiopathologic processes linking OSAS and CAD and in the treatment of OSAS in this specific population.
This is a single center, randomized controlled trial which will include women with ischemic heart disease to receive either a self-directed stress reduction program delivered through a smart-phone application or activity tracking only for the first month ("early SR intervention" and "delayed SR intervention", respectively). Patients will be monitored for 1 month for application use and step counts via telephone or email interview and/or collection of screen-captured data. Baseline questionnaires will be repeated at the end of one month to assess for all primary and secondary measures, at which time the control group (activity tracking only) will be introduced to the intervention program. The early SR intervention group will not receive a new intervention but will be encouraged to continue using the app. Data will be collected for an additional 2 months with all participants in both groups. After the three-month study period, the study will close with the collection of final questionnaire data.
A randomised controlled trial to compare two strategies for the investigation of coronary artery disease at the time of angiography. Patients will be randomised to conventional angiography or additional, routine pressure wire assessment - measuring fractional flow reserve (FFR) - in all main vessels judged as being of sufficient vessel calibre to allow percutaneous coronary intervention (PCI) (experimental arm).
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.
