Esmolol cardioplegia in unstable coronary revascularisation patients

Background: Esmolol has been studied and applied to control hypertension and tachycardia during open heart surgery. Esmolol has been used on a minor scale as a single cardioplegic agent. Little information is available on esmolol as a component of blood cardioplegia. In this prospective, randomised, double‐blind clinical study we investigated whether esmolol improves cardioprotection in patients scheduled for an urgent coronary operation.
