What is the role of preoperative ECG and chest X-ray in low-risk patients without symptoms or risk factors?

• A. Not routinely required; consider if age, comorbidity, or symptoms suggest risk.
• B. Always required.
• C. Never useful.
• D. Only used after surgery.

Answer: (A)

In preoperative assessment, the aim is to identify problems that would change how you manage the patient around surgery. For someone who is low-risk, has no symptoms, and lacks risk factors, routine testing with an ECG or a chest X-ray often doesn’t provide useful information and may even cause harm. The findings are frequently benign or nonspecific and rarely prompt a change in the perioperative plan, while false positives can lead to unnecessary further testing, delays, anxiety, and added radiation exposure.

Therefore, these tests are not routinely performed in truly low-risk, asymptomatic patients. They should be considered only when there are signs that a cardiac or pulmonary issue might be present—such as age-related risk, known comorbidities (like heart or lung disease), or new or changing symptoms (chest pain, palpitations, dyspnea) or abnormal physical exam findings. In that context, an ECG could uncover occult rhythm disorders or ischemia, and a chest X-ray might reveal issues that would alter anesthesia or surgical planning. In the absence of such indicators, skip the routine preoperative ECG and chest X-ray.
