Anesthesia Risk Stratification for Cardiac Patients (ASA + Cardiac Modifiers)

: Explanation and Clinical Context This tool combines the ASA Physical Status (ASA-PS) classification with cardiac-specific “risk modifiers” and the presence of active cardiac conditions to structure perioperative decision-making for patients with cardiovascular disease who are undergoing noncardiac surgery. The ASA-PS conveys baseline physiological reserve and comorbidity burden, and the emergency modifier “E” indic
