Our mission is to promote excellence in clinical diagnosis, research, technical development, and education in cardiovascular imaging in Europe.
Our mission: To promote excellence in research, practice, education and policy in cardiovascular health, primary and secondary prevention.
Our goal is to reduce the burden in cardiovascular disease in Europe through percutaneous cardiovascular interventions.
Our Mission is "to improve the quality of life of the population by reducing the impact of cardiac rhythm disturbances and reduce sudden cardiac death"
To improve quality of life and logevity, through better prevention, diagnosis and treatment of heart failure, including the establishment of networks for its management, education and research.
Working Groups goals is to stimulate and disseminate scientific knowledge in different fields of cardiology.
ESC Councils goal is to share knowledge among medical professionals practising in specific cardiology domains.
OUR MISSION: TO REDUCE THE BURDEN OF CARDIOVASCULAR DISEASE
Dr. Lino Manuel Goncalves,
Top researchers in this field presented their latest results to the nearly 100 people who attended this session. Lively discussions took place after each presentation, enriching the session.
de Windt from Utrech, the Netherlands, presented the topic : “ Calcium regulation in the cardiac myocyte as a signal for cellular remodeling”. After a short review of the intracellular calcium signaling pathway, he showed data supporting that Mir-199b antagomir delivery reduces calcineurin-induced hypertrophy in vivo. Dyrk1a regulates NFAT and is involved in heart failure in animal models, and in humans as well. Mir-199 antagomir delivery restores functional Dyrk1a expression in vivo. Kranias, a researcher from Cincinnati, USA, addressed the topic: “Phospholamban binding partners and myocyte survival”. She started her presentation describing the role of phospholamban (Pho) in the SRCa++ transport. In fact, when overexpressed Pho reduces cardiac contractitlity. HAX-1 has demonstrated to interact with Pho in cardiac extracts, and it has been localized to mitochondria. HAX-1 prevents cell death and its action is enhanced in the presence of Pho, by a mechanism involving caspase 3. HAX-1 down regulation leads to an increase in contractility both in vitro and in vivo. HAX-1 attenuates cardiomyocyte calcium transients through the inhibition of SR calcium uptake. Overexpression of HAX-1 reduces infarct size. The inducible expression of I-1c influences Pho phosporilation and reduces infarct size in ischemia/reperfusion models. This mechanism is mediated by ER stress responses during ischemia/reperfusion. Moreover, she showed data supporting the view that gene therapy with Ad-I-1c restores Emax in failing rat hearts. Sipido, from Leuven, Belgium, presented data on myocardial remodeling in atrial fibrillation. A review on excitation-contraction and calcium handling in chronic atrial fibrillation was provided by her at the beginning of her presentation. Sheeps with atrial fibrillation were studied . The myocytes in these animals showed a smaller and slower contraction, associated with myocyte hypertrophy. Calcium transients are also reduced in this animal model. These animals also showed a reduction in T-tubule density in the atrium, but not in the ventricle. In this model it was also observed a reduction of calcium release in both the longitudinal and transversal axis. Ertl, from Wurzburg, Germany, addressed the topic: “Post-infarct remodeling: the heart as a wound”. He reviewed the mechanisms involved in the post-infarct remodeling process as well as the interventions which can potentially interfere with wound healing post-Mi. There are several conditions associated with impaired wound healing, such as male gender, post-menopause female, age, diabetes, clotting factor XIII deficiency, among others. In Factor XIII homozygote knock-out mices show a reduced survival after MI. When the factor XIII is administered to these animals they show an intermediate survival. These results can be explained by an inadequate inflammation, inadequate fibrosis, and apoptosis. In a mice model of osteogenesis imperfecta an impairment of healing can also be observed after MI.
