Among the 265/338 dogs for which a follow‐up was available, 173/265 (65%) died. 68% (118/173) of deaths were cardiac in origin (CD) with a median time to CD of 25.1 months after diagnosis [IQR=8.3‐52.7]. Univariate analyses revealed that RF>70%, left atrium to aorta ratio≥1.5 at end‐diastole, left ventricular dilation, ACVIM stages, presence of arrhythmias, and collapse were significantly associated with time to CD. Dogs from ACVIM stage B had a median time to decompensation of 15.9 months [IQR=8.2‐45.0], and a median time to CD of 42.9 months [IQR=19.1‐56.1] versus 17.8 [IQR=5.4‐38.4] for dogs from stage C and D.
