Patient age in years at the time of surgery. Risk increases continuously with age.
years
American Society of Anesthesiologists (ASA) physical status classification.
Ability to perform activities of daily living without assistance before surgery.
Serum creatinine above 1.5 mg/dL (133 umol/L) indicates impaired renal function and raises cardiac risk.
Select the planned surgical procedure category from the ACS NSQIP classification.

Estimated perioperative MICA risk: 0.13% - Low risk.

  • Patients with predicted risk below 1% typically require no additional preoperative cardiovascular testing per ACC/AHA guidelines.

Next stepNo additional cardiac testing is generally required, but continue standard perioperative monitoring and document the risk discussion in the patient's record.
