Reference intervals of two-dimensional speckle tracking-derived endocardial global longitudinal strain analysis in 132 healthy cats.

Introduction: The assessment of left ventricular myocardial deformation and function by two-dimensional speckle tracking-derived strain analysis is an established method in human cardiology. It also progressively gains recognition in veterinary cardiology in both dogs and cats.

Objectives: The objectives of this study were to create reference intervals for two-dimensional speckle tracking echocardiography (STE)-derived endocardial global longitudinal strain (GLS) in a population of healthy adult cats of different breeds.
