Activation of IP prostanoid receptors prevents cardiomyocyte hypertrophy via cAMP-dependent signaling.

According to a study from Australia, "The antihypertrophic action of angiotensin-converting enzyme inhibitors in the heart results partly from local potentiation of bradykinin. We have demonstrated that the antihypertrophic action of bradykinin is mediated by the release of nitric oxide from endothelium and elevation of cardiomyocyte cGMP. Whether other paracrine factors derived from the coronary endothelium, such as prostacyclin (PGI2 ), may act to prevent hypertrophy has not been explored."
