Revised Cardiac Risk Index

  • Identification of patients at high rate of complications who are undergoing elective cardiac surgery.
  • 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"
2. History of congestive heart failure
3. History of cerebrovascular disease
4. Insulin therapy for diabetes
5. Renal insufficiency
6. High risk type surgery (intraperitoneal, intrathoracic, or vascular surgery above the inguinal ligaments)
  • Rates of major cardiac complications increased with 2 or more risk factors of revised cardiac risk index.[3]

Surgery Specific Risk - 2007 ACC/AHA Guidelines

  • Vascular surgery has a risk more than 5%
    • Aortic surgeries
    • Peripheral vascular surgery
  • Intermediate risk surgeries are as follows:(1- 5% risk)
    • Intraperitoneal
    • Intrathoracic
    • Carotid endarterectomy
    • Head and neck surgery
    • Orthopedic surgery
    • Prostate surgery
  • Low risk:(< 1%)
    • Endoscopic procedures
    • Superficial procedures
    • Cataract surgery
    • Breast surgery
    • Ambulatory surgery

Cardiac Conditions with Increased Pre-operative Risk

1. Unstable Coronary Syndromes

  • Unstable or severe angina (Canadian Cardiovascular Society class III or IV): May include “stable” angina in patients who are unusually sedentary.
  • Recent MI: Greater than 7 days, but less than or equal to 1 month (within 30 days).

2. Decompensated HF

  • NYHA functional class IV
  • Worsening or new-onset heart failure

3. Significant Arrhythmias

4. Severe Valvular Disease

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).

Calculating the Weekly Energy Expended in Recreational-time Physical Activity using METs (Metabolic equivalent task)[7]

Physical Activity MET
Light Intensity Activities < 3
Sleeping 0.9
Watching television 1.0
Writing, desk work, typing 1.8
Walking, 1.7 mph (2.7 km/h), level ground, strolling, very slow 2.3
Walking, 2.5 mph (4 km/h) 2.9
Moderate Intensity Activities 3 to 6
Bicycling, stationary, 50 watts, very light effort 3.0
Walking 3.0 mph (4.8 km/h) 3.3
Calisthenics, home exercise, light or moderate effort, general 3.5
Walking 3.4 mph (5.5 km/h) 3.6
Bicycling, <10 mph (16 km/h), leisure, to work or for pleasure 4.0
Bicycling, stationary, 100 watts, light effort 5.5
Vigorous Intensity Activities > 6
Jogging, general 7.0
Calisthenics (e.g. pushups, situps, pullups,jumping jacks), heavy, vigorous effort 8.0
Running jogging, in place 8.0
Rope jumping 10.0

Cardiac Risk Stratification for Non-cardiac Surgical Procedures

High (Reported cardiac risk often greater than 5%)

  • Aortic and other major vascular surgery.
  • Peripheral vascular surgery.
  • Anticipated prolonged surgical procedures associated with large fluid shifts and/or blood loss.

Intermediate (Reported cardiac risk generally 1% to 5%)

  • Carotid endarterectomy.
  • Head and neck surgery.
  • Intraperitoneal and intrathoracic surgery.
  • Orthopedic surgery.
  • Prostate surgery.

Low (Reported cardiac risk generally less than 1%)

  • Endoscopic procedures.
  • Superficial procedure.
  • Cataract surgery.
  • Breast surgery.
  • Ambulatory surgery.
Key points about NST
  • No Class I recommendation
  • Class IIa recommendation in patients with
    • >= 3 risk factors
    • Functional capacity of < 4 METs
    • High risk surgery (Vascular surgery)

Pre-operative Stress Testing

  • For patients who are able to exercise : Treadmill Exercise ECG.
  • For patients who are unable to exercise : Pharmacological Stress Imaging.

Electrocardiogram - Treadmill Exercise ECG

Risk Assessment
Risk METs Heart rate
High Risk - Ischemia induced by low level of exercise < 4 < 100 or 70% age pred. max
Intermediate Risk - Ischemia induced by moderate exercise 4 - 6 > 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.

Techniques

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.
  • It has high negative predictive value (93-100%)
  • It has low positive predicitive value (5 - 33%)
  • Extent of regional wall motion abnormality and low threshold of ischemia is an important predictor of post operative events.

Radionuclide Myocardial Perfusion Imaging

  • Stress nuclear myocardial perfusion imaging has a high sensitivity for detecting patients at risk for perioperative cardiac events.
  • It has high negative predictive value (95-100%)
  • It has low positive predictive value (5- 20%)
  • 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)

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.

Class I recommendation
Class IIa recommendation


2014 ACC/AHA Guideline on Perioperative Cardiovascular Evaluation and Management of Patients Undergoing Noncardiac Surgery[14]

Clinical Risk Factors[14]

Valvular Heart Disease[14]

Class I
"1. It is recommended that patients with clinically suspected moderate or greater degrees of valvular stenosis or regurgitation undergo preoperative echocardiography if there has been either 1) no prior echocardiography within 1 year or 2) a significant change in clinical status or physical examination since last evaluation(Level of Evidence: C)"
"2. . For adults who meet standard indications for valvular intervention (replacement and repair) on the basis of symptoms and severity of stenosis or regurgitation, valvular intervention before elective noncardiac surgery is effective in reducing perioperative risk(Level of Evidence: C)"
Class IIa
"1. Elevated-risk elective noncardiac surgery with appropriate intraoperative and postoperative hemodynamic monitoring is reasonable to perform in patients with asymptomatic severe aortic stenosis (Level of Evidence: B)"
"2. . Elevated-risk elective noncardiac surgery with appropriate intraoperative and postoperative hemodynamic monitoring is reasonable in adults with asymptomatic severe MR (Level of Evidence: C)"
"3. Elevated-risk elective noncardiac surgery with appropriate intraoperative and postoperative hemodynamic monitoring is reasonable in adults with asymptomatic severe aortic regurgitation and a normal left ventricular ejection fraction (Level of Evidence: C)"
Class IIb
"1. . Elevated-risk elective noncardiac surgery using appropriate intraoperative and postoperative hemodynamic monitoring may be reasonable in asymptomatic patients with severe mitral stenosis if valve morphology is not favorable for percutaneous mitral balloon commissurotomy. (Level of Evidence: C)"

Other clinical risk factors[14]

Class I
"1. Before elective surgery in a patient with a CIED, the surgical/procedure team and clinician following the CIED should communicate in advance to plan perioperative management of the CIED.(Level of Evidence: C)"
"2.Chronic pulmonary vascular targeted therapy (i.e., phosphodiesterase type 5 inhibitors, soluble guanylate cyclase stimulators, endothelin receptor antagonists, and prostanoids) should be continued unless contraindicated or not tolerated in patients with pulmonary hypertension who are undergoing noncardiac surgery.(Level of Evidence: C)"
Class IIa
"1. Unless the risks of delay outweigh the potential benefits, preoperative evaluation by a pulmonary hypertension specialist before noncardiac surgery can be beneficial for patients with pulmonary hypertension, particularly for those with features of increased perioperative risk (Level of Evidence: C)"


Approach to perioperative cardiac testing[14]

Multivariate risk indices[14]

Class IIa
"1. A validated risk-prediction tool can be useful in predicting the risk of perioperative MACE in patients undergoing noncardiac surgery (Level of Evidence: B)"
Class III (No Benefit)
"1.For patients with a low risk of perioperative MACE, further testing is not recommended before the planned operation (Level of Evidence: B)"


Supplemental preoperative evaluation[14]

The 12-Lead Electrocardiogram[14]

Class IIa
"1. . Preoperative resting 12-lead electrocardiogram (ECG) is reasonable for patients with known coronary heart disease, significant arrhythmia, peripheral arterial disease, cerebrovascular disease, or other significant structural heart disease, except for those undergoing low-risk surgery (Level of Evidence: B)"
Class IIb
"1. Preoperative resting 12-lead ECG may be considered for asymptomatic patients without known coronary heart disease, except for those undergoing low-risk surgery (Level of Evidence: B)"
Class III (No Benefit)
"1. Routine preoperative resting 12-lead ECG is not useful for asymptomatic patients undergoing low-risk surgical procedures (Level of Evidence: B)"

Assessment of Left Ventricular Function[14]
