Epinephrine

A Percutaneous Coronary Intervention term on the RCIS exam blueprint, defined for cath lab and EP clinicians.

An increasingly utilized front-line therapy, particularly vital when no-reflow causes severe systemic hypotension that contraindicates the use of vasodilatory agents like adenosine or nitroprusside. Administered in 50 to 200 µg intracoronary boluses, epinephrine's beta-2 agonism drives potent microvascular dilation, while its simultaneous beta-1 effects provide essential inotropic support to the stunned myocardium.
