The Congress "Knowing and Treating the Heart", organized annually by the Center for the Fight against Heart Attack, has become for 41 years now a scientific event particularly awaited by Italian cardiologists due to the variety, characteristics and relevance of the topics covered. This year's edition, the 41st, will also offer a very vast program which, as always, will stimulate lively discussion among participants. The topics that will be presented and discussed will, in fact, concern the progress that continues to be made, both in the diagnosis and therapy of many cardiovascular pathologies, thanks to the results of molecular biology research, experimental studies, pathophysiology, epidemiological investigations and above all of clinical studies.
