Key result
Gaining body weight over the course of disease was associated with significantly longer survival in dogs with heart failure compared to losing or maintaining weight (P=0.04).
Why the study?
Do changes in body weight and body condition predict survival in dogs with heart failure?
Population
108 dogs with heart failure secondary to dilated cardiomyopathy or chronic valvular disease

Should not yet change weight management in canine heart failure; extends obesity paradox observations but remains hypothesis-generating.

Do changes in body weight and body condition predict survival in dogs with heart failure?
p-value: p=0.04
In dogs with heart failure, gaining body weight and n-3 fatty acid intake are associated with longer survival, suggesting an obesity paradox similar to that seen in humans.
Slupe et al. (2008) conducted a cohort in Heart failure (n=108). Changes in body weight vs. Maintained or lost body weight was evaluated on Survival time (p=0.04). Gaining body weight over the course of disease was associated with significantly longer survival in dogs with heart failure compared to losing or maintaining weight (P=0.04).
