Heart and brain: a case of focal myocytolysis in severe pneumococcal meningoencephalitis with review of the contemporary literature.
We report electrocardiographic changes mimicking myocardial ischaemia in a 73-year-old man with fatal pneumococcal meningoencephalitis, present the autopsy-confirmed histological picture of extensive focal myocytolysis (contraction band necrosis) without myocardial infarction or myocarditis, and review the contemporary literature. Potentially reversible, probably non-ischaemic myocardial dysfunction may occur in association with acute noncardiac illnesses, such as brain injuries. Biochemical and morphological abnormalities in acutely failing hearts from head-injured organ donors point to specific pathophysiological mechanisms, which are different from heart failure from other causes. Sepsis-related factors may add to the myocardial dysfunction in patients with brain injury from meningoencephalitis.
