Why the study?
PGF2α may have therapeutic utility as a non-catecholaminergic inotrope, but its effect on hypertrophied hearts had not previously been examined.
Does Prostaglandin F2α improve left ventricular developed pressure in isolated perfused rat hearts with right ventricular hypertrophy?
Comparison
0.3 μM PGF2α vs 0.03 μM isoproterenol
Design

May support rate-independent inotropy in hypertrophied hearts but risks arrhythmias; leaves open translation to clinical RV failure.
Does Prostaglandin F2α improve left ventricular developed pressure in isolated perfused rat hearts with right ventricular hypertrophy?
PGF2α provides positive inotropic support without increasing heart rate in rat hearts, but may cause arrhythmias in the setting of right ventricular hypertrophy at a dose of 0.3 μM.
