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

Original / Goldman Index

Goldman et.al devised a cardiac index for preoperative evaluation in 1977. ^[2]

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

Mobitz II atrioventricular block
Third degree AV block
Symptomatic ventricular arrhythmias
Supraventricular arrhythmias (including atrial fibrillation) with uncontrolled ventricular rate (HR greater than 100 bpm at rest)
Symptomatic bradycardia
Newly recognized ventricular tachycardia

4. Severe Valvular Disease

Severe aortic stenosis (mean pressure gradient >40 mm Hg, aortic valve area <1.0 cm2, or symptomatic)
Symptomatic mitral stenosis (progressive dyspnea on exertion, exertional presyncope, or heart failure)

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).

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

Increasing oxygen demand of the heart either by pacing or inotropes
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.
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)

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.
