title: The myocardial renin-angiotensin system: existence, importance, and clinical implications.
abstract: Major components of the renin-angiotensin system have been localized to cardiac tissue. Cardiac-derived angiotensin II may benefit myocardial contractility but may promote detrimental myocardial hypertrophy, coronary vasoconstriction, and arrhythmias. The benefits of ACE inhibition probably extend beyond the classic circulating RAS to include the heart directly.
