The most famous such example is Secretariat. His autopsy showed beyond a shadow of a doubt that he had an oversized heart, weighing in at 22 pounds, nearly three times that of the average thoroughbred, and more than three times that of an average non-thoroughbred horse.
Secretariatâs heart was over 278% bigger than the size of a normal horseâs heart. Secretariat was great because he had a huge heart. He could run and run and run because of the size of his heart. He completed some of the most impressive athletic feats of the 20th century because of his enlarged heart.
