Synopsis
Estimate cardiovascular risk before non-cardiac surgery, identify conditions that need treatment or delay, and plan proportionate investigation, medicines and postoperative surveillance.
- Start with surgical urgency: emergency treatment must not be delayed by tests that cannot change immediate management.
- Estimate both procedure-related risk and patient-related risk; previous cardiovascular disease, symptoms, frailty, renal disease and diabetes materially alter risk.
- New chest pain, decompensated heart failure, unstable arrhythmia or severe symptomatic valve disease requires assessment before elective surgery proceeds.
- Functional capacity is clinically useful: inability to climb two flights of stairs or perform moderate activity suggests reduced reserve but is not a diagnosis.
- Order a preoperative test only when the result could change the operation, anaesthetic plan, treatment or postoperative monitoring.
- Do not request routine resting echocardiography; use it for unexplained dyspnoea, heart-failure features or a murmur with cardiac symptoms when the result will affect care.
- Document a procedure-specific plan for anticoagulants, antiplatelets, implanted cardiac devices and chronic cardiovascular medicines.
- For selected higher-risk patients, perioperative troponin surveillance can detect otherwise silent myocardial injury and should trigger clinical assessment rather than an isolated laboratory label.
