Filter by:This is a prospective randomized controlled trial assessing the impact of notifying patients and their clinicians of an incidental finding of coronary artery calcification (CAC) indicating increased cardiovascular risk. Patients will be identified through completed radiology orders for non-gated, non-contrast chest CT in the appropriate clinical context and then will have an EHR screen for inclusion criteria. The presence of CAC will be confirmed by a board-certified physician. Eligible patients will be randomized to CAC notification or usual care using a 1:1 stratified block randomization method based on baseline statin use.
Clinical study: - Methods: observational transversal two-arm cohort study including adults living with HIV (PLHIV) and HIV negative subjects (HIV-) at intermediate cardiovascular risk. No study specific interventions were performed. - Participants: consecutively recruited at two large public hospitals in Paris and Annecy, France where participants were referred for routine cardiac risk stratification. - Recruitment: was from June 2013 until April 2016. - Data: anonymous study data were collected during the ambulatory visit. No follow-up was conducted. Study objectives: - Primary: compare coronary artery calcification (CAC) score between PLHIV and HIV- in order to bridge gaps in current knowledge. - Secondary: assess parameters linked to CAC score including predictors and their prevalence, association with carotid/femoral atherosclerosis, and cardiovascular risk scores (ASCVD and HEART score). Study hypotheses: - Primary: CAC scores would not be different between PLHIV and HIV- - Secondary: prevalence of traditional CV risk factors would be lower in PLHIV but that HIV-related nontraditional CV risk factors (including lower grade chronic inflammation, immune dysregulation, and ARV exposure duration) would be associated with higher CAC scores and higher CV risk scores Study Rational: - PLHIV have an increased risk of atherosclerotic cardiovascular events compared to the general population. Primary prevention for PLHIV is important but challenging as traditional cardiovascular risk scores do not account for HIV-related factors. - Computed tomography coronary artery calcium (CAC) score using the Agatston score is useful for detecting and quantifying coronary calcifications. In the general population, CAC score is predictive of future cardiovascular events.
Recruiting patients who were diagnosed with HFpEF. Using Non-contrast CT to measure the total Agatston coronary artery calcification score, epicardial adipose tissue volume and attenuation. Analysing the correlation between them.
thoracic pain is one of the most frequent reasons for consulting the emergency room. Chest pain can be a sign of different pathologies with a wide range of severity, from life-threatening aortic dissection or myocardial infarction to chest pain during an anxiety attack. Efficient triage of patients is therefore a crucial issue for emergency physicians in order not to ignore an acute coronary event requiring early and specific management. The investigators seek to evaluate whether a diagnostic strategy based on a thoracic CT scan to rule out coronary calcifications and a single troponin assay can exclude an acute coronary event with sufficient accuracy compared to usual management.
The aim of this study will be to compare the effectiveness of an exercise therapy program with extracorporeal shockwave therapy, ultrasound-guided percutaneous irrigation and a wait and see approach in people with rotator cuff calcific tendinopathy.
Previous studies have suggested that restenosis (RS) after stenting is mainly due to smooth muscle cell proliferation and migration, but recent evidence suggests that in-stent restenosis（ISR） is associated with a number of factors. Coronary artery calcification is an independent predictor of ischaemia-mediated revascularisation 1 year after percutaneous coronary intervention (PCI) following RS.The characteristics of new neointima in patients with in-stent restenosis of calcified lesions are important issues to explore
This is a prospective and multicenter clinical investigation aiming to evaluate the safety and effectiveness of coronary atherectomy system for the treatment of patients with coronary calcification.
Does an educational intervention for untreated COPD and cardiovascular disease which is integrated in an existing lung cancer screening program improve guideline concordant medication adherence at 12 months
This is a French, prospective, single-arm, multi-center registry to confirm the safety and efficacy of the Diamondback 360 TM Orbital Atherectomy System in the preparation of de novo calcified coronary lesions before implantation of a coronary endoprothesis in adult subjects. The primary safety endpoint is 30-day MACE and the efficacy endpoint is procedural success.
Coronary artery narrowings interfere with blood flow to the heart which can cause chest pain and heart attacks. Cardiologists can treat these narrowings with balloons and stents. However, some narrowings can become very calcified and hard making treatment with balloons and stents difficult. Rotational atherectomy is a tool to treat calcific coronary disease. It uses an ablative drill to break down the hardened plaques inside the coronary arteries facilitating subsequent treatment with balloons and stents. However, during this procedure patients can experience a slow heart rate which may compromise procedural safety. Cardiologists may use a temporary pacemaker that is inserted by separately accessing the heart through a large vein usually from the leg. This maintains a safe heart rate throughout the procedure. However, inserting the temporary pacemaker is associated with additional complications. We have developed and propose an alternative strategy to provide a temporary safety pacemaker during rotational atherectomy without the need for inserting an additional pacemaker.
