PGA1's positive inotropy in dogs may inform HF drug development; leaves open human translation.
Do PGA1, nitroprusside, and diazoxide affect myocardial contractile force in dogs?
PGA1 has a direct positive inotropic effect, unlike diazoxide (negative) and nitroprusside (neutral), suggesting potential utility in heart failure.
Slotkoff et al. (1979) studied this question.
