Coronary artery disease
3

4
Valvular heart disease
1
Beta blockers
2
ACE inhibitors
3
Aspirin
4
Allergic to latex
Perform a physical examination of the patient
Conduct a thorough physical examination of the patient, focusing on cardiovascular health. This includes checking blood pressure, heart rate, and listening for abnormal heart sounds. A physical examination helps in identifying any signs of cardiac dysfunction or disease that may impact the surgical outcome.
1
Blood pressure measurement
2
Heart rate and rhythm assessment
3
Evaluation of heart sounds
4
Assessment of peripheral pulses
Determine patient's current functional capacity
Assess the patient's current functional capacity, which reflects their ability to tolerate the physiological stress of surgery. This is crucial in evaluating the patient's risk for perioperative cardiac events and determining the appropriate level of preoperative cardiac optimization.
1
High
2
Intermediate
3
Low
Identify the presence of diabetes or kidney disease
Check for the presence of diabetes or kidney disease as they are significant risk factors for perioperative cardiac complications. Both conditions require careful management during the perioperative period to minimize adverse outcomes.
1
Diabetes
2
Chronic kidney disease
3
Both
4
None
Collect data on certain known cardiovascular risk factors
Gather information on specific cardiovascular risk factors that can impact the patient's surgical outcomes. These risk factors include smoking, obesity, family history of cardiovascular disease, and history of stroke.
1
Smoking status
2
Body mass index (BMI)
3
Family history of cardiovascular disease
4
History of stroke
Evaluate the type of surgery for its cardiac risk
Assess the type of surgery the patient is scheduled to undergo to determine its associated cardiac risk. Certain surgical procedures, such as major vascular surgeries or complex cardiac surgeries, pose a higher risk and may require additional cardiac evaluations or interventions.
1
Minor procedure (e.g., cataract surgery)
2
Intermediate procedure (e.g., hernia repair)
3
Major procedure (e.g., coronary artery bypass graft)
Perform non-invasive stress testing if required
If indicated based on the patient's clinical characteristics and surgical procedure, perform non-invasive stress testing to further assess the patient's cardiac function and identify any ischemic or arrhythmic abnormalities. Stress testing helps in risk stratification and guiding further management decisions.
1
High-risk surgery with poor functional capacity
2
History of ischemic heart disease
3
Severe valvular heart disease
Determine the need for further cardiovascular evaluation
Based on the preoperative risk assessment, decide whether the patient requires further cardiovascular evaluation by a cardiologist. This may include additional diagnostic testing or consultation for optimizing the patient's cardiac status before surgery.
1
Yes
2
No
Evaluate other clinical factors that may influence perioperative cardiac risk
Consider other clinical factors that may impact the patient's perioperative cardiac risk. These factors include advanced age, frailty, renal dysfunction, and the presence of other significant comorbidities. Assessing these factors helps in individualizing the patient's perioperative management.
1
Advanced age (≥ 65 years)
2
Frailty
3
Renal dysfunction
4
Significant comorbidities
Perform echocardiography if indicated
If indicated based on the preoperative risk assessment, perform echocardiography to obtain detailed information about the patient's cardiac structure and function. Echocardiography helps in identifying any significant valvular abnormalities or systolic/diastolic dysfunction that may impact perioperative care.
1
Valvular heart disease
2
Suspected ventricular dysfunction
3
Infective endocarditis
Review Chest X-Ray results
Review the patient's Chest X-Ray results to assess the condition of the heart, lungs, and surrounding structures. Chest X-Ray findings can provide valuable information for perioperative cardiac risk assessment, especially in identifying cardiomegaly, pulmonary congestion, or signs of previous cardiac surgeries.
1
Cardiomegaly
2
Pulmonary congestion
3
Signs of previous cardiac surgery
4
Normal
Conduct consultation with a cardiologist if required
If the preoperative risk assessment indicates the need for further cardiovascular evaluation or management, consult with a cardiologist to obtain expert advice. Collaboration with a cardiologist can optimize the patient's cardiac status and reduce the risk of perioperative cardiac events.
Decide on the need for preoperative medical therapy
Based on the preoperative risk assessment, determine whether the patient requires any preoperative medical therapy to optimize their cardiac status. This may include medication adjustments, initiation of new therapies, or lifestyle modifications to reduce perioperative cardiac risks.
1
Beta blockers
2
Statins
3
Aspirin
4
Lifestyle modifications
Establish a plan for postoperative cardiac care
Develop a comprehensive plan for postoperative cardiac care to ensure optimal recovery and minimize the risk of complications. This may include close monitoring, medication adjustments, cardiac rehabilitation referrals, and appropriate follow-up appointments.
1
Intensive care unit (ICU) monitoring
2
Medication adjustments
3
Cardiac rehabilitation referral
4
Follow-up appointment

Inform the patient and the surgical team about the risks and the plan
Communicate the findings of the preoperative cardiac risk assessment to both the patient and the surgical team. Clearly explain the identified risks, the planned interventions, and the expected outcomes. This promotes shared decision-making and ensures everyone is well-informed.
1
Preoperative cardiac risk assessment findings
2
Planned interventions
3
Expected outcomes
Document the preoperative cardiac risk assessment
Thoroughly document the findings and recommendations of the preoperative cardiac risk assessment. This serves as a crucial record for future reference and ensures that the information is easily accessible to the healthcare team involved in the patient's perioperative care.
Schedule the surgery if all parameters are acceptable
If all the parameters from the preoperative cardiac risk assessment meet the acceptable thresholds, proceed with scheduling the surgery. Ensure proper coordination with the surgical team, anesthesiologist, and other relevant healthcare providers to avoid any scheduling conflicts or delays.
Initiate necessary preoperative therapies
Initiate any necessary preoperative therapies based on the findings of the preoperative cardiac risk assessment. This may include medication optimization, smoking cessation counseling, or referral for cardiac interventions like percutaneous coronary intervention (PCI) or valve replacement.
