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.
Projects
The immature heart is highly tolerant to ischemic injury, but chronic oxygen deficit during early ontogeny may have negative consequences that persist till adulthood. We study mechanisms responsible for developmental changes of cardiac ischemic tolerance.

Systemic hypertension is a major risk factor of ischemic heart disease. However, it can also stimulate mechanisms that protect the heart against acute oxygen deprivation. We study the effects of various forms of hypertension on cardiac ischemic tolerance.

Prolonged exposure to hypoxic environment leads to adaptation which is associated with improved cardiac tolerance to acute oxygen deprivation. We study molecular mechanisms underlying the cardioprotective effects of chronic hypoxia on various manifestations of ischemic injury.
