Key result
Treadmill exercise in conscious dogs increased left atrial reservoir function (systolic pulmonary venous flow volume) from 38% at baseline to 52% (P<0.005).
Why the study?
Does treadmill exercise alter left atrial function in conscious dogs?
Does treadmill exercise alter left atrial function in conscious dogs?
Absolute Event Rate: 52% vs 38%
p-value: p=<0.005
In conscious dogs, dynamic exercise augments left atrial reservoir and booster functions, which may play an important role in accelerating left ventricular filling.

LA reservoir dynamics during exercise remain preclinical; leaves open translation to human HF or AF management.
Nishikawa et al. (1994) studied this question. Treadmill exercise vs. Baseline was evaluated on Systolic pulmonary venous blood flow (PVF) volume as a percentage of total PVF volume (p=<0.005). Treadmill exercise in conscious dogs increased left atrial reservoir function (systolic pulmonary venous flow volume) from 38% at baseline to 52% (P<0.005).
