Degenerative mitral valve disease: Survival of dogs attending primary-care practice in England. Mattin MJ, Boswood A, Church DB, McGreevy PD, O'Neill DG, Thomson PC, Brodbelt DC. (May 2015; Epub ahead of print) Preventive Veterinary Medicine


As part of her ongoing PhD research, primary author Maddy Mattin undertook a retrospective cohort study of dogs diagnosed with degenerative mitral valve disease (DMVD) and  dogs classified as possible cases (i.e. with heart murmurs consistent with DMVD) attending primary-care practices in England, to evaluate survival characteristics of affected dogs. Cases were identified via electronic patient records (EPRs) of practices sharing data with VetCompass; searches encompassed EPRs from 111,967 dogs, attending 93 veterinary practices between January 2010 and December 2011.  Kaplan-Meier curves were used to explore survival characteristics of study dogs and Cox regression modelling identified factors associated with hazard of death.

Alongside useful findings on mean ages of diagnosis and death, the study highlights poorer survival for all-cause mortality in Cavalier King Charles spaniels (CKCSs) and larger dogs affected. These reported survival characteristics clarify vital clinical features of canine DMVD, which could aid veterinary surgeons' advising clients on prognoses for their affected pets and better inform evaluation of the impact this condition has on dogs at a population level.
