Stepwise Approach to Pre-operative Cardiac Assessment
Adapted from Fleisher et al. Circulation. 2009 Nov 24;120(21):e169-276[1]; HR, Heart rate
§,∧ Noninvasive testing is not useful for patients with no clinical risk factors undergoing intermediate-risk or low-risk noncardiac surgery (AHA guidelines Class III, Level of Evidence: C).
¶Clinical risk factors: Ischemic heart disease, compensated or prior heart failure, diabetes mellitus, renal insufficiency, and cerebrovascular disease.
Cardiac Risk Index

Goldman et.al devised a cardiac index for preoperative evaluation in 1977. [2]
PO2 < 60mmHg; PCO2 > 50mmHg; K < 3mmol/l; HCO3 < 20mmol/l; urea >18mmol/l (BUN > 50mg/dl); Creatinine > 260umol/l (3mg/dl); bedridden from non-cardiac cause

Risk stratification with non invasive techniques.[3]
Revised Cardiac Risk Index
1. History of ischemic heart disease Includes "history of myocardial infarction, history of a positive exercise test, current complaint of chest pain considered to be secondary to myocardial ischemia, use of nitrate therapy, or ECG with pathological Q waves" Excludes: "patients with prior coronary revascularization procedures were categorized as having ischemic heart disease only if they had any of the other criteria"
Estimated Energy Requirements for Various Activities
The metabolic equivalent of task (MET), or simply metabolic equivalent, is a physiological concept expressing the energy cost of physical activities[4] as multiples of resting metabolic rate (RMR) and is defined as the ratio of metabolic rate (and therefore the rate of energy consumption) during a specific physical activity to a reference rate of metabolic rate at rest, set by convention to 3.5 ml O2·kg-1·min-1 or equivalently 1 kcal·kg-1· h-1 or 4.184 kJ·kg-1· h-1. By convention 1 MET is considered as the resting metabolic rate obtained during quiet sitting[5][6] . MET values of physical activities range from 0.9 (sleeping) to 18 (running at 17.5 km/h or a 5:31 mile pace).

> 100 - 130 or 70 - 85% of age pred. max
Low Risk - No ischemia or ischemia induced at higher level of exercise
> 7
> 130 or > 85% of age pred. max
Inadequate test : In patients undergoing non cardiac surgery ,the inabilty to exercise to a level of 4 - 6 METs without out ischemia should be considered as inadequate test. (Stage II Bruce protocol)
Pre-operative 12 Lead ECG
The time frame for ECG testing is fixed, it can be done within 30 days of planned surgery when indicated.
The resting 12-lead ECG did not identify increased perioperative risk in patients undergoing low-risk surgery.
In patients with coronary disease, the resting 12-lead ECG may have contains important prognostic information relating to long-term morbidity and mortality.
Non invasive Stress Testing (NST)
These are used for preoperative evaluation of patients undergoing non cardiac surgery. These are used in patients who cannot exercise.
Increasing blood supply (hyperemic response) by vasodilators
Dobutamine Stress Echocardiography
Increasing doses of supratherapeutic doses of dobutamine are infused , which increases myocardial contractility and heart rate. This leads to significant coronary artery stenosis which can be identified by regional wall-motion abnormalities within the distribution of the affected vessels.
Perioperative cardiac risk is directly proportional to the myocardium at risk detected by the extent of reversible defects found on imaging.
It is of high clinical value when used for selective population of high clinical risk.
In Left Bundle-Branch Block
Exercise may at times induce reversible septal defects in the absence of LAD disease. Specificity of exercise myocardial perfusion imaging in presence of LBBB is low.
Pharmacologic strss testing with perfusion scintigraphy or DSE is preferred over exercise stress testing.
Perioperative Revascularization Therapy
Extensive ischemia is a risk factor for increased peri-operative events
Pre-op coronary revascularization does not prevent death or MI. [8]
Pre-operative CABG
Patients who have high-risk coronary anatomy and in whom long-term outcome would likely be improved by CABG should generally undergo coronary revascularization before a noncardiac elective vascular surgical procedure or noncardiac operative procedures of intermediate or high risk. [9]
The cumulative mortality and morbidity of both the coronary revascularization procedure and the noncardiac surgery should be weighed carefully. The individual patient’s overall health,functional status, and prognosis have to be taken into consideration. [10]
Pre-operative PCI
Prophylactic preoperative PCI in non cardiac surgical procedures is of no value in preventing perioperative cardiac events. [11]
Unscheduled noncardiac surgery in a patient who has undergone a prior PCI presents special challenges, particularly with regard to management of the dual-antiplatelet agents required in those who have received coronary stents.
Following flowchart depicts the approach based on expert opinion[12] in patients who have undergone successful coronary intervention with or without stent placement before planned or unplanned noncardiac surgery.

Perioperative Medical Therapy
Beta Blockers
Key points about perioperative beta blocker therapy
Start well before surgery. ( minimum of 1 week - don't start on the day of surgery)
Use is in high or intermediate risk population only.
Titrate dose to heart rate and blood pressure starting with a low dose. (Fixed doses shouldn't be used)
Long acting betablockers are better to use.
If intra-operative heat rate goes above 80 start IV administration.(Look for alternative causes of tachycardia)
For more information on perioperative betablocker therapy click here.
Statins
Statins have protective effective on cardiac complications in non cardiac surgery, but the dosage and the target levels are unclear.
Utilizing the perioperative period as an opportunity to impact long-term health, consideration should be given to starting statin therapy in patients who meet National Cholesterol Education Program criteria.
Alpha 2 Agonists
Strong evidence is lacking for the recommendation of clonidine for blood pressure control.
Administration of clonidine had minimal effects on hemodynamics and post operative mortality.

"4. Patients with poor (less than 4 METs) or unknown functional capacity and no clinical risk factors should proceed with planned surgery. (Level of Evidence: B)"
"1. It is probably recommended that patients with functional capacity greater than or equal to 4 METs without symptoms proceed to planned surgery.§(Level of Evidence: B)"
"2. It is probably recommended that patients with poor (less than 4 METs) or unknown functional capacity and 3 or more clinical risk factors who are scheduled for vascular surgery consider testing if it will change management.¶(Level of Evidence: B)"
"3. It is probably recommended that patients with poor (less than 4 METs) or unknown functional capacity and 3 or more clinical risk factors who are scheduled for intermediate risk surgery proceed with planned surgery with heart rate control.¶(Level of Evidence: B)"
"4. It is probably recommended that patients with poor (less than 4 METs) or unknown functional capacity and 1 or 2 clinical risk factors who are scheduled for vascular or intermediate risk surgery proceed with planned surgery with heart rate control.¶(Level of Evidence: B)"
"1. Noninvasive testing might be considered if it will change management for patients with poor (less than 4 METs) or unknown functional capacity and 3 or more clinical risk factors who are scheduled for intermediate risk surgery. (Level of Evidence: B)"
"2. Noninvasive testing might be considered if it will change management for patients with poor (less than 4 METs) or unknown functional capacity and 1 or 2 clinical risk factors who are scheduled for vascular or intermediate risk surgery. (Level of Evidence: B)"
"2. It is reasonable for patients with current or prior heart failure with worsening dyspnea or other change in clinical status to undergo preoperative evaluation of LV function if not performed within 12 months. (Level of Evidence: C)"
"1. Preoperative resting 12-lead ECG is recommended for patients with at least 1 clinical risk factor who are undergoing vascular surgical procedures. (Level of Evidence: B)"
"1. Preoperative and postoperative resting 12-lead ECGs are not indicated in asymptomatic persons undergoing low-risk surgical procedures. (Level of Evidence: B)"
"1. Preoperative resting 12-lead ECG is reasonable in persons with no clinical risk factors who are undergoing vascular surgical procedures. (Level of Evidence: B)"
"1. Preoperative resting 12-lead ECG may be reasonable in patients with at least 1 clinical risk factor who are undergoing intermediate-risk operative procedures. (Level of Evidence: B)"
"1. Patients with active cardiac conditions in whom noncardiac surgery is planned should be evaluated and treated per ACC/AHA guidelines before noncardiac surgery. (Level of Evidence: B)"
"1. Noninvasive testing is not useful for patients with no clinical risk factors undergoing intermediate-risk noncardiac surgery. (Level of Evidence: C)"
"2. Noninvasive testing is not useful for patients undergoing low-risk noncardiac surgery. (Level of Evidence: C)"
"1. Noninvasive stress testing of patients with 3 or more clinical risk factors and poor functional capacity (less than 4 METs) who require vascular surgery is reasonable if it will change management. (Level of Evidence: B)"
"1. Noninvasive stress testing may be considered for patients with at least 1 to 2 clinical risk factors and poor functional capacity (less than 4 METs) who require intermediate-risk noncardiac surgery if it will change management. (Level of Evidence: B)"
"2. Noninvasive stress testing may be considered for patients with at least 1 to 2 clinical risk factors and good functional capacity (greater than or equal to 4 METs) who are undergoing vascular surgery. (Level of Evidence: B)"
Preoperative Coronary Revascularization With CABG or Percutaneous Coronary Intervention (DO NOT EDIT)[1]
"2. In patients who have received drug-eluting coronary stents and who must undergo urgent surgical procedures that mandate the discontinuation of thienopyridine therapy, it is reasonable to continue aspirin if at all possible and restart the thienopyridine as soon as possible. (Level of Evidence: C)"
"1. The usefulness of preoperative coronary revascularization is not well established in high-risk ischemic patients (e.g., abnormal dobutamine stress echocardiograph with at least 5 segments of wall-motion abnormalities). (Level of Evidence: C)"
"1. For patients with at least 1 clinical risk factor who are undergoing intermediate-risk procedures, statins may be considered. (Level of Evidence: C)"
"1. Preoperative intensive care monitoring with a pulmonary artery catheter for optimization of hemodynamic status might be considered; however, it is rarely required and should be restricted to a very small number of highly selected patients whose presentation is unstable and who have multiple comorbid conditions. (Level of Evidence: B)"
"1. The usefulness of intraoperative nitroglycerin as a prophylactic agent to prevent myocardial ischemia and cardiac morbidity is unclear for high-risk patients undergoing noncardiac surgery, particularly those who have required nitrate therapy to control angina. The recommendation for prophylactic use of nitroglycerin must take into account the anesthetic plan and patient hemodynamics and must recognize that vasodilation and hypovolemia can readily occur during anesthesia and surgery. (Level of Evidence: C) "
"1. The emergency use of intraoperative or perioperative transesophageal echocardiography is reasonable to determine the cause of an acute, persistent, and life-threatening hemodynamic abnormality. (Level of Evidence: C)"
"1. Maintenance of body temperature in a normothermic range is recommended for most procedures other than during periods in which mild hypothermia is intended to provide organ protection (eg, during high aortic cross-clamping). (Level of Evidence: B)"
Blood Glucose Concentration Control (DO NOT EDIT)[1]
"1. It is reasonable that blood glucose concentration be controlled during the perioperative period in patients with diabetes mellitus or acute hyperglycemia who are at high risk for myocardial ischemia or who are undergoing vascular and major noncardiac surgical procedures with planned intensive care unit admission. (Level of Evidence: B) "
"1. The usefulness of strict control of blood glucose concentration during the perioperative period is uncertain in patients with diabetes mellitus or acute hyperglycemia who are undergoing noncardiac surgical procedures without planned intensive care unit admission. (Level of Evidence: C)"
"1. Routine use of a pulmonary artery catheter perioperatively, especially in patients at low risk of developing hemodynamic disturbances, is not recommended. (Level of Evidence: A)"
"1. Use of a pulmonary artery catheter may be reasonable in patients at risk for major hemodynamic disturbances that are easily detected by a pulmonary artery catheter; however, the decision must be based on 3 parameters: patient disease, surgical procedure (ie, intraoperative and postoperative fluid shifts), and practice setting (experience in pulmonary artery catheter use and interpretation of results), because incorrect interpretation of the data from a pulmonary artery catheter may cause harm. (Level of Evidence: B)"
Intraoperative and Postoperative ST Segment Monitoring (DO NOT EDIT)[1]
"1.Intraoperative and postoperative ST segment monitoring can be useful to monitor patients with known CAD or those undergoing vascular surgery, with computerized ST segment analysis, when available, used to detect myocardial ischemia during the perioperative period. (Level of Evidence: B)"
"1. Intraoperative and postoperative ST segment monitoring may be considered in patients with single or multiple risk factors for CAD who are undergoing noncardiac surgery. (Level of Evidence: B)"
Surveillance for Perioperative MI (DO NOT EDIT)[1]
"1. The use of postoperative troponin measurement is not well established in patients who are clinically stable and have undergone vascular and intermediate-risk surgery. (Level of Evidence: C)"
Perioperative Beta-Blocker Therapy (DO NOT EDIT)[1]
"1.Beta blockers should be continued in patients undergoing surgery who are receiving beta blockers for treatment of conditions with ACCF/AHA Class I guideline indications for the drugs. (Level of Evidence: C)"
"1.Beta blockers should not be given to patients undergoing surgery who have absolute contraindications to beta blockade. (Level of Evidence: C)"
"2. Routine administration of high-dose beta blockers in the absence of dose titration is not useful and may be harmful to patients not currently taking beta blockers who are undergoing noncardiac surgery.[15](Level of Evidence: B)"
"2.Beta blockers titrated to heart rate and blood pressure are reasonable for patients in whom preoperative assessment for vascular surgery identifies high cardiac risk, as defined by the presence of more than 1 clinical risk factor.* (Level of Evidence: C)"
"3.Beta blockers titrated to heart rate and blood pressure are reasonable for patients in whom preoperative assessment identifies coronary artery disease or high cardiac risk, as defined by the presence of more than 1 clinical risk factor,* who are undergoing intermediate-risk surgery.[18](Level of Evidence: B)"
"1. The usefulness of beta blockers is uncertain for patients who are undergoing either intermediate-risk procedures or vascular surgery in whom preoperative assessment identifies a single clinical risk factor in the absence of coronary artery disease.* (Level of Evidence: C)"
"2. The usefulness of beta blockers is uncertain in patients undergoing vascular surgery with no clinical risk factors* who are not currently taking beta blockers.[19](Level of Evidence: B)"
“
* Clinical risk factors include history of ischemic heart disease, history of compensated or prior heart failure, history of cerebrovascular disease, diabetes mellitus, and renal insufficiency (defined in the Revised Cardiac Risk Index as a preoperative serum creatinine of >2 mg/dL).[3]
