Neonatal cat myocardial data warrant no clinical extrapolation; leaves open postnatal contractile maturation mechanisms for translational study.
Post-natal developmental changes occur in the contractile properties of the cat myocardium, with neonates showing less developed tension and greater resting tension compared to adults.
Davies et al. (1975) studied this question.
