Prognostic interaction between clinical stage and left atrial remodeling in dogs with myxomatous mitral valve disease
Abstract
Myxomatous mitral valve disease (MMVD) is leading cause of acquired heart failure in small-breed dogs. Although the American College of Veterinary Internal Medicine (ACVIM) staging is widely used in practice, how each stage and the degree of cardiac remodeling affect survival has not been clearly defined. We aimed to determine whether severe remodeling in dogs with preclinical (stage B2) disease is associated with survival differences compared with dogs with congestive heart failure (CHF; stage C) and less severe remodeling. This retrospective study analyzed 270 dogs with MMVD, stratified by the left atrium-to-aortic root ratio as having mild (
