Filter by:The field of oncology has advanced remarkably. Some of the old and new emerging cancer therapies are associated with development of cardiovascular toxicities , which may have the potential to offset the gains in survival obtained with this cancer treatment advances. Much of the focus on cardiovascular toxicities has been in the early detection of myocardial damage and prediction of cancer therapeutics-related cardiac dysfunction (CTRCD). The main strategy for these patients is timely diagnosis and treatment of high-risk individual Cardiac dysfunction associated with cancer treatment is the main cause of mortality in cancer survivors. The mortality rate is recorded to be up to 60% in the first two years after therapy. The most commonly associated drugs with cardiotoxicity are anthracycline (AC) and monoclonal antibodies (such as trastuzumab). Other new agents, such as vascular endothelial growth factor (VEGF) inhibitors, immunotherapies, and proteasome inhibitors, can also cause cardiac dysfunction .
The purpose of the study is to determine the normal variation of T1 values with cardiac magnetic resonance in healthy individuals with respect to reproducibility, changes over time, and dependency on hydration status.
Background: Severe aortic valve stenosis (AS) is the commonest valve disease. Aortic valve replacement (AVR) is primarily indicated when symptoms occur and/or when there is a drop in left ventricular ejection fraction. However, irreversible myocardial damage, such as replacement fibrosis, leads to increased morbidity and mortality despite treatment. Improved patient selection and timely treatment is thus warranted. T1 mapping, a non-invasive method to quantify myocardial fibrosis by cardiac magnetic resonance (CMR), could be a marker to guide treatment. Aims: To investigate the change of myocardial fibrosis* in AS patients following AVR and if these changes are associated with disease and/or procedural characteristics. Methods: This is an observational clinical trial. Approximately 60 patients with severe AS planned to undergo AVR (either surgical or transcatheter) at Rigshospitalet, Denmark will be included. Participants will undergo CMR before surgery and at a 1-year follow-up. Other assessments include clinical evaluation and blood sampling. The primary end-point is change in T1 values after AVR. Hypotheses and perspectives: The investigators hypothesize that (1) myocardial fibrosis* will regress in patients undergoing AVR as a group, (2) the degree of myocardial fibrosis is positively correlated with the degree of symptoms, (3) the regression of myocardial fibrosis is greater in patients undergoing TAVR compared to SAVR, and (4) the regression of myocardial fibrosis is greater in patients with tricuspid aortic stenosis compared to bicuspid aortic stenosis. Ultimately, T1 mapping is a potential marker for improved patient selection for the timing of AVR. * Estimated by T1 mapping
The study will analyze the prevalence of cardiac involvement of health care workers from the University Hospital of Salamanca (HUSA) who have overcome SARS-CoV-2 infection. Participants will undergo a clinical evaluation, electrocardiogram (EKG), cardiac magnetic resonance (CMR) and blood analysis including NT-proBNP, troponin, cellular and humoral immunity and genetics.
CARTIER (Cardiotoxicity in the elderly) is a prospective cohort study of newly diagnosed elderly cancer patients equal or greater than 65 years of age conduced in one tertiary center (Hospital Universitario de Salamanca at Spain. The study is academically funded in its integrity by The Instituto de Salud Carlos III (Spanish Ministry of Science, Innovation and Universities). The investigators of the study are the only responsible for the study design, data collection, and data interpretation. All study participants provide written informed consent. All enrolled patients will undergo serial surveys, 6-minutes walking test (6MWT), electrocardiogram, echocardiogram, blood samples, CMR, physical examinations and multidisciplinary clinical evaluations; before each chemotherapy cycle and at 3, 6, 9 and 12 months, 3 years and 5 years after finalization of chemotherapy, except for MRI that will be performed before 1st, 3rd, 5th cycles and at 3, 6, 9,12 months, 3 years and 5 years after chemotherapy ending
