Abstract:
Background: Cardiomyopathies are a group of diseases of the heart that can lead to
heart failure, cardiac arrhythmia, and sudden death. They typically manifest as an enlarged heart or
a normal heart with microscopic anomalies (fibrosis, inflammation, etc.). The aim of the study is to
investigate the prevalence of deaths due to cardiomyopathies of unknown etiology in young subjects
in a forensic pathology setting.
Materials and Methods: Deaths due to cardiomyopathy in decedents less than 40 years old evaluated
at the Cook County Medical Examiner’s Office in Chicago from January 2013 to June 2018
were studied.
Results: In total, 140 cases of cardiomyopathies were identified in the study period: among these,
in 20 cases (14%), no underlying etiology could be found through medical history and autopsy
investigation. The demographics and the macroscopic and microscopic findings of these cases are
described, highlighting the importance of medical history review and adequate histological sampling
of hearts in cases of sudden, unexpected death in children and young adults.
Conclusion: This study highlights the importance of medical history review and adequate histological
sampling of hearts in cases of sudden, unexpected death in children and young adults to
identify possible cardiomyopathies of unknown etiology.
