Left atrial pump strain

1. Skeletal muscle mass index mediates left atrial pump strain in humans (36% mediated (95% CI 20–59%)).

1. Leisure-time physical activity is associated with left atrial pump strain in humans (β = -1.674).

   “PA was significantly associated with LA reservoir strain (β = 2.907, p < 0.001) and with pump strain (β = -1.674, p < 0.001).”
