No immediate clinical implications for human myocardium; leaves open translational relevance of phased rat ventricular growth.
Grimm et al. (1966) studied Myocardial growth and hypertrophy. Ventricular growth and hypertrophy was evaluated on Myocardial DNA, RNA, actomyosin, and total protein concentrations. Myocardial growth in rat ventricles occurs in three phases with varying DNA and RNA concentrations, while total protein and actomyosin levels remain unchanged.
