Filter by:We will test an ultrasound device that uses sound waves to detect the fetal heart beat, and use this device to tell the MRI scanner when to collect pictures of the fetal heart. This will help freeze motion of the fetal heart, to make MRI pictures sharper. This will be important for assessing human fetal heart disease, an active area of research at our institution.
Iron is involved in essential functions of the body. It allows the transport of oxygen in the blood, via hemoglobin, at the muscular level, via myoglobin, and it is also involved in cellular metabolism in general, in particular for the production of ATP at the mitochondrial level, within the cytochromes and iron-sulfur proteins of the respiratory chain. Recently, iron deficiency has been identified as an important prognostic factor in heart failure patients. Iron therapy improves symptoms and physical performances of heart failure patients, even in the absence of anemia. As a result, the correction of iron deficiency is now proposed as one of the therapies for heart failure. However, the pathophysiology of the association between cardiac dysfunction and iron deficiency is still poorly understood. The investigators previously developed a mouse model of iron deficiency without anemia, in which the investigators observed impaired physical performances, a decrease of left ventricular ejection fraction, and a decrease in mitochondrial complex I activity. These abnormalities were normalized after iron injection. These animal data suggest that iron deficiency is responsible for left ventricular dysfunction secondary to mitochondrial I complex abnormalities, and that iron therapy corrects them. Iron deficiency is very common in the preoperative period of cardiac surgery, affecting 40 to 50% of patients. During this surgery, it is possible to perform a myocardial biopsy without risk to the patient. The purpose of this study is to verify in patients requiring valvular heart surgery, if iron deficiency is responsible for a decrease in mitochondrial complex I activity and a decrease in cardiac function during the perioperative period, and to verify whether iron treatment improves these abnormalities.
One-center, observational, non-interventional, prospective study of the efficacy of azilsartan medoxomil in patients with arterial hypertension associated with stable ischemic heart disease and type 2 diabetes mellitus.
The PRODOSE trial is investigating a bespoke pharmacokinetic algorithm that calculates a tailored dose of protamine, required after cardiopulmonary bypass to reverse the action of heparin, based on individual patients and their actual bypass time. The PRODOSE trial aims to demonstrate that the algorithm can be used to define a protamine dose that will more reliably return coagulation parameters to pre-heparin levels as well as decreasing the risk of post-operative bleeding and transfusion. The trial aims to recruit 200 patients who will be randomised to either a bespoke or standard dose of protamine. The randomisation ratio will be 1:1 in the first instance but the trial uses an adaptive design and an interim analysis will be conducted after 100 patients have been randomised. The randomisation ratio could then be updated after the interim analysis to favour a superior arm whilst preserving statistical power levels.
Antineoplastic and immunomodulating agents may lead to various cardio-vascular adverse reactions. This study investigates reports of cardio-vascular toxicities for treatment including Anatomical Therapeutic Chemical (ATC) classification L (antineoplastic agents, endocrine therapy, immunostimulants, and immunosuppressants drugs) in the World Health Organization's (WHO) global database of individual safety case reports (VigiBase).
RAPID-VT Pilot is a single centre prospective cohort pilot study to assess the feasibility, safety and efficacy of catheter ablation of ventricular tachycardia (VT) guided by a novel real-time software to localize the origin of VT during the ablation procedure.
The purpose of this retrospective study is to determine the incidence and severity of acute kidney injuries (AKI) after heart surgery on cardiopulmonary bypass (CPB) in the pediatric intensive care unit (PICU) in Lausanne, Switzerland.
EUROASPIRE is a multicentre European study in coronary patients and individuals at high risk of developing cardiovascular disease (CVD), describing their management through lifestyle and use of drug therapies and providing an objective assessment of clinical implementation of current scientific knowledge. Four EUROASPIRE surveys have been carried out by the European Society of Cardiology so far: EUROASPIRE I in 1995-1997 in nine countries, EUROASPIRE II in 1999- 2000 in 15 countries, EUROASPIRE III in 2006-2009 in 22 countries and EUROASPIRE IV in 2012-2015 in 26 countries. The results showed a wide gap between the recommendations and clinical practice with many patients not achieving the lifestyle and medical risk factors goals for CVD prevention. The fifth EUROASPIRE survey is planned for 2016-2018 to determine in hospital coronary patients and apparently healthy individuals in primary care at high risk of developing cardiovascular disease whether the European and national guidelines on cardiovascular disease prevention have been followed and if the practice of preventive cardiology in EUROASPIRE IV has improved by comparison with those centres which took part in EUROASPIRE I, II, III and IV. This survey will also incorporate an assessment of dysglycaemia and kidney function in all patients. The main outcome measures will be the proportions of coronary and high cardiovascular risk patients achieving the lifestyle, risk factor and therapeutic targets for cardiovascular disease prevention. The data collection will be based on a review of patient medical records and a patient interview and examination at least 6 months and at most 3 years after recruiting event. All countries which participated in the first three surveys will be invited to take part in EUROASPIRE V. This fifth survey will give a unique picture of preventive action by cardiologists and primary care physicians looking after patients with coronary disease and individuals at high CVD risk.
The overall objective of this study is to use patient-centered in vitro and in vivo models to answer the fundamental question of whether or not pathogenic mutations in BRCA1/2 result in an increased risk of CV disease
Immune checkpoint inhibitors (ICIs) might have high grade immune-related adverse events (irAEs) from rhumatologic, endocrinologic, cardiac or other system origin. This study investigates reports of drug induced irAEs with treatment including anti-PD1, Anti-PDL-1, and Anti-CTLA4 classes using the World Health Organization (WHO) database VigiBase and the french database Base Nationale de PharmacoVigilance (BNPV).
