Why the study?
Heart diseases in aging pets predispose to arrhythmias that can worsen underlying cardiac conditions, making arrhythmia identification important for establishing therapeutic protocols and prognosis.
Does structural heart disease increase the risk of arrhythmias in dogs?
Population
586 medical records of dogs treated at SCDR-UFRRJ
Comparison
Presence vs absence of heart disease, sex, age group, and size
Design
Retrospective observational study
Key result
Structural heart disease in dogs significantly increased the risk of developing rhythm or conduction alterations (OR 4.46; p=0.0003).

Mendonça et al. (2022) conducted an observational in Structural heart disease and arrhythmias in dogs (n=586). Structural heart disease vs. Absence of structural heart disease was evaluated on Rhythm or conduction alterations (arrhythmias) (OR 4.46, p=0.0003). Structural heart disease in dogs significantly increased the risk of developing rhythm or conduction alterations (OR 4.46; p=0.0003).
