Note: Feline populations are defined by age quartile at the time of study entry when they were diagnosed as apparently healthy or preclinical HCM/HOCM. Data are arranged by cause of death.
Abbreviations: HCM, nonobstructive hypertrophic cardiomyopathy; HOCM, obstructive hypertrophic cardiomyopathy.
*
Includes all cardiovascular, noncardiovascular, and unknown causes of death.
**
Death related to anesthesia, respiratory diseases, central nervous system diseases, hepatobiliary diseases, toxicoses, endocrine diseases, trauma.
