About the department
Ischemic heart disease is the main cause of mortality worldwide. We study cardiac tolerance to injury caused by acute oxygen deprivation from the molecular level to the whole organism using animal models. Our research is focused mainly on the study of mechanisms that underlie:
- high cardiac tolerance to injury early ontogeny,
- increased cardiac tolerance induced by adaptation to chronic hypoxia and regular exercise training,
- permanent consequences of early developmental interventions for cardiac tolerance in adulthood,
- and altered cardiac tolerance associated with various pathological states.
Further we study heart development with special emphasis on the cardiac conduction system. Our current research is focused on the following projects:
- elucidating cardiac conduction system formation with phylogenetic approaches,
- dynamic imaging methods for cardiac conduction system,
- and development of new methods for quantitative analysis of fibrous structures to study branching patterns of the coronary vessels and cardiac conduction system.
13th conference New Frontiers in Basic Cardiovascular Research
New Frontiers in Basic Cardiovascular Research 2018
13th conference New Frontiers in Basic Cardiovascular Research in November 11 – 14, 2018 in Prague, Czech Republic.
Cardiovascular diseases are the leading causes of death and disability worldwide and the situation in new EU countries is particularly serious. There is, therefore, an urgent need to improve understanding of pathogenetic mechanisms underlying an initiation and progression of cardiovascular diseases as a prerequisite for developing novel therapeutic strategies and their translation to clinical settings. This goal cannot be achieved without sharing knowleddge and enhancing international cooperation and training. The planned meeting is a continuation of traditional series of meetings that started in Prague in 1994 and was followed every other year by meetings held in one of the V4 countries or in France (Smolenice 1996, Strasbourg 1998, Mariánské Lázně 2000, Smolenice 2002, Montpellier 2004, Debrecen 2006, Krakow 2008, Toulouse 2010, Hradec Králové 2012, Smolenice 2014 and Paris 2016). These meetings significantly improved scientific interaction and collaboration among researchers from these countries resulting in increasing success of joint grant applications and quality of joint publications.
The meeting will bring together researchers mainly from V4 countries, other new EU countries and France in order to strengthen communication and mutual collaboration, thereby accelerating scientific progress in cardiovascular research. Furthermore, it will provide an important opportunity for early stage researchers and pregraduate and postgraduate students to present and discuss their projects and results with established investigators in order to facilitate their involvement in scientific cooperation and exchange training in laboratories within new EU countries and France. The project coordinator and his team will be responsible for the organization of the meeting, selection of participants from the Czech Republic and coordination of participation of French distinguished cardiologists. Partners from other V4 countries will select participants from Slovakia, Hungary and Poland in cooperation with the project coordinator in order to create excellent and attractive scientific program and promote joint research activities. The meeting will be held in the project coordinator’s organization – the Institute of Physiology of the Czech Academy of Sciences.

In our research, we use mostly laboratory rats and mice including suitable transgenic models. Cardiac tolerance to injury caused by temporal coronary artery occlusion and reperfusion is studied in anesthetized open-chest animals, isolated perfused hearts are used to assess tolerance to injury due to global or regional ischemia/reperfusion, and isolated ventricular myocytes serve to analyze the effects of simulated anoxia/reoxygenation. As major manifestations of injury we evaluate the size of myocardial infarction, the incidence and severity of ventricular arrhythmias, the postischemic recovery of contractile function, and the viability of myocytes. Echocardiography and catheterization techniques are used to assess heart functions and hemodynamics. To study cardioprotective mechanisms we employ suitable pharmacological tools and biochemical analyses.
