Influence of Signalment Variables on Body Weight-Normalized Echocardiographic Measurements of Heart Size in 56 169 Adult Unsedated Normal Pure-Bred Cats

Breed, age, sex, and neutering status had small and mostly clinically irrelevant effects on BW-normalized Ao, LA, and LV linear dimensions. The PE and PI intervals are valid in adult pure-bred cats across many breeds, different ages, sexes, and neutering status.
