Snippet: In healthy dogs, strain rate showed a moderate negative relationship with heart rate (r2=0.35) and a weak positive relationship with body weight (r2=0.13); strain showed no relationships with heart rate or bodyweight. Strain and strain rate showed weak positive relationships with LA:Ao in MMVD dogs without PH (r2=0.2 and r2=0.18). Strain and strain rate showed strong positive relationships with TR velocity in dogs with PH (r2=0.7). Only TR veloci.....
Document: In healthy dogs, strain rate showed a moderate negative relationship with heart rate (r2=0.35) and a weak positive relationship with body weight (r2=0.13); strain showed no relationships with heart rate or bodyweight. Strain and strain rate showed weak positive relationships with LA:Ao in MMVD dogs without PH (r2=0.2 and r2=0.18). Strain and strain rate showed strong positive relationships with TR velocity in dogs with PH (r2=0.7). Only TR velocity was retained in a multivariable model to predict strain and strain rate in dogs with PH; heart rate, bodyweight and LA:Ao were excluded. Both strain and strain rate showed good sensitivity (100%), but modest specificity (70%) for identifying severe PH.
