In Secretariat's autopsy, conducted after his death in 1989, it was discovered that he had an extremely large heart, weighing about 22 pounds, which is significantly larger than the average horse's heart. This condition, known as "cardiac hypertrophy," likely contributed to his extraordinary racing abilities, enabling him to pump more blood and deliver greater oxygen to his muscles. Additionally, the autopsy revealed other abnormalities, including a highly developed vascular system. Overall, the findings provided insights into the remarkable physiology that contributed to his legendary performance on the racetrack.
