Incidence of myocardial dysfunction in studies with severe sepsis patients is up to two thirds of patients. On the other side, patients with normal echocardiography have some type of myocardial injury, which can be detected by elevated serum levels of troponins and natriuretic peptides. Strong prognostic value of these markers regarding morbidity and mortality of septic patients indicates an important role of this "occult" myocardial injury. ⋯ Nowadays, because of detrimental effects of classical inotropes, new strategies are under investigation. Namely levosimendan is promising alternative, not only related to its inotropic effects. Early diagnostics, assessment of prognosis and therapeutic strategy in patients with SMD are challenging for continuing research and for clinicians of different specialities.

Review[Myocardial dysfunction in sepsis--definition and pathogenetic mechanisms].
Sepsis is considered to be the major cause of morbidity and mortality of patients hospitalised in intensive care. It's defined as a systemic inflammatory response of organism to infection. Incidence of myocardial dysfunction in studies with severe sepsis patients is up to two thirds of patients. ⋯ Reversibility of myocardial dysfunction during a period from 7 to 10 days in survivors is other typical manifestation of SMD. Hence, one can speculate that development of such a type ofSMD as a temporary protective compensatory mechanism could be advantageous for of an individual patient. A large body ofevidence about mechanisms ofSMD was described; endothelial dysfunction with consequent microcirculatory and mitochondrial dysfunction and role of circulating factors are considered to be the most important.
