Do histological alterations differ between pressure-overloaded and volume-overloaded right ventricular myocardium in cats?
Pressure overload, unlike volume overload, induces an increase in connective tissue and decrease in cardiocyte volume density in the right ventricle, potentially explaining the specific contractile dysfunction seen in pressure overload.
Marino et al. (1985) studied this question.
