title: Cardiomyopathy in captive owl monkeys (Aotus nancymae).
abstract: Dilated cardiomyopathy (DCM) was identified histopathologically in a colony of owl monkeys (Aotus nancymae) over a 15-year period. We characterized the incidence of cardiac disease echocardiographically in the colony over a 14-month period. Of 77 monkeys, 21 had systolic myocardial failure, and postmortem examination confirmed the antemortem diagnosis of DCM in eight animals. Monkeys with a questionable diagnosis at the first examination demonstrated progression of disease with time. Left ventricular end-systolic cross-sectional area and left ventricular fractional area change were the indices that most reliably discriminated between normal and diseased animals. Serum cardiac troponin I concentrations were below detectable limits in normal and diseased monkeys. The apparent high prevalence of disease in this colony precluded establishment of reference intervals for Aotus nancymae. Our study provides the first comprehensive echocardiographic evaluation of owl monkeys with cardiomyopathy.
