Esmolol or Nitroglycerin Infusion for Blood Pressure Control Prior to Cardiopulmonary Bypass (CPB) in Cardiac Surgery
This is an investigator initiated, sponsored, open label, prospective randomized controlled trial to be performed in adult patients undergoing scheduled cardiac surgery. Patients will be randomized to esmolol infusion or nitroglycerin infusion for control of hypertension that occurs during cardiac surgery from induction of anesthesia to initiation of cardiopulmonary bypass (CPB).

- Esmolol or Nitroglycerin Infusion for Blood Pressure Control Prior to Cardiopulmonary Bypass in cardiac surgery: a randomized, clinical trial [ Time Frame: Participation could last up to 2 weeks, representing the day of surgery until discharge from the hospital. ] [ Designated as safety issue: No ]The extent of diastolic hypotension below the clinical target range (measured as area under the curve below the lower diastolic pressure expressed in mmHg*min/hr
- Title: Systolic or diastolic hypertension; systolic hypotension [ Time Frame: Duration: during infusion of study drug ] [ Designated as safety issue: No ]drug dose; time to BP control; infusion duration; need to stop study drug; tachycardia; postbypass HR; pacemaker placement; drug infusion to support separation from bypass; time to extubation; ICU and hospital length of stay; new atrial fibrillation or organ dysfunction
