Brief Summary
Patients on a stable dose of ACE inhibitor or ARB medication who are scheduled for elective surgery will be randomized to take their ACE inhibitor or ARB up to and including the morning of surgery, or to hold them a day prior to the surgery. The patients will be followed for 30 days after surgery to assess any adverse health outcomes.

Study Arms (2)
Continuing ACEi/ARB
ACTIVE COMPARATORPatients in this group will continue to take their chronic ACEi/ARB medications up to and including the day of surgery.
Holding ACEi/ARB
ACTIVE COMPARATORPatients in this arm will hold their chronic ACEi/ARB medication at least 24 hours prior to surgery.
Interventions
Patients will either hold their chronic ACEi/ARB medication for at least 24 hours prior to surgery, or continue to take the ACEi/ARB medication up to and including the day of surgery
