Reversible myocardial dysfunction in critically ill, noncardiac patients:: A review

Objective: To review reversible myocardial dysfunction affecting critically ill patients without cardiac pathology. Data sources. The bibliography for the study was compiled through a search of different databases for the period 1966-2001. References cited in the selected articles also were reviewed. Study Selection: The selection criteria included all articles published on reversible myocardial dysfunction In critically ill patients. Conclusions. Reversible myocardial dysfunction may develop in a situation of critical pathology, but the etiology of reversible myocardial dysfunction is not fully understood. This dysfunction may be accompanied by Increases In enzyme concentrations and electrocardiographic changes. Reversible myocardial dysfunction probably is underdiagnosed, although Its presence Is associated with a worsening of the prognosis and with more specific therapeutic options. Further studies are necessary to define Its true Incidence and clinical implications.
