CARDIAC RISK
ASSESSMENT FOR
NONCARDIAC
SURGERY
JOHN HAMATY D.O.
SOUTH JERSEY HEART GROUP

INTRODUCTION:
CAD ACCOUNTS FOR THE MOST
DEATHS IN PTS UNDERGOING
NONCARDIAC SURGERY.
5% OF ELDERLY POPULATION IN US
UNDERGO NONCARDIAC
SURGERY/YR.
30% ARE AT RISK FOR CAD WITH INHOSPITAL COMPLICATIONS IN 1.5 MIL.
PTS.
PERIOPERATIVE RISK OF
EVENTS
PATIENTS WITH NO PRIOR HISTORY
OF MYOCARDIAL INFARCTION HAVE A
LOW RISK OF PERIOPERATIVE
MI(0.1%-0.6%)
PATIENTS WITH A HISTORY OF PRIOR
MI ARE AT A SIGNIFICANTLY HIGHER
RISK (2.8%-7%).
PERIOPERATIVE RISK OF EVENTS
(HISTORY OF PRIOR MI)
MI WITHIN 3 MOS.-37% INCREASE IN
EVENTS
MI WITHIN 3-6MOS.-16% INCREASE IN
EVENTS
MI GREATER THAN 6 MOS.-4%
INCREASE IN EVENTS
A STEPWISE APPROACH
FOR PERIOPERATIVE RISK
ASSESSMENT OF A PATIENT
UNDERGOING NONCARDIAC
SURGERY
URGENCY OF SURGERY
ALL PATIENTS UNDERGOING URGENT
SURGERY SHOULD BE BETA-BLOCKED
TO A HEART RATE OF 50 BEATS/MIN
AND A BLOOD PRESSURE THAT IS
CONTROLLED.
PRIOR REVASCULARIZATION
PTS WHO HAVE UNDERGONE
COMPLETE REVASCULARIZATION IN
THE FORM OF CORONARY ARTERY
BYPASS OR PTCA WITHIN 6 MONTHS
TO 5 YEARS AND ARE FUNCTIONALLY
ACTIVE AND HAVE NO CLINICAL
EVIDENCE OF ISCHEMIA DO NOT
NEED FURTHER CARDIAC TESTING.
PRIOR EVALUATION FOR
CAD
PTS. THAT HAVE BEEN EVALUATED IN
THE PAST TWO YEARS WITH EITHER
INVASIVE OR NONINVASIVE
TECHNIQUES WITH FAVORALE
FINDINGS GENERALLY DO NOT NEED
FURTHER EVALUATION.
MUST BE FREE OF CARDIAC
SYMPTOMS AND OR SIGNS OF
ISCHEMIA
PRESENCE OF CLINICAL
RISK FACTORS
HISTORY, PHYSICAL AND ECG ARE
GENERALLY SUFFICIENT TO ESTIMATE
CARDIAC RISK
ASSESSMENT OF CLINICAL RISK
FUNCTIONAL CAPACITY
PREDICTORS OF INCREASED
PERIOPERATIVE CV RISK
