Coronary angiography is an invasive test used to visualize the coronary arteries. It is not a routine screening test for every person with cardiovascular risk factors. Whether it is appropriate depends on symptoms, prior non-invasive testing, clinical likelihood of obstructive coronary disease and the treatment question.
Where angiography fits in the diagnostic pathway
The 2024 ESC chronic coronary syndrome guidance places testing in a risk-based pathway. Non-invasive testing is often used first, while invasive coronary angiography is considered in selected patients with a high likelihood of obstructive disease, severe symptoms despite treatment or other high-risk features.
Records to send before travelling
A German cardiology team can review the diagnostic question more efficiently when previous testing is available.
- Recent cardiology summary and symptom history
- ECG and echocardiography reports
- Stress test, coronary CT or cardiac imaging when already performed
- Previous angiography or PCI reports and images
- Medication list and relevant blood tests
- Kidney-function results and major allergies when known
Angiography and treatment are separate decisions
Finding a coronary narrowing does not automatically mean that a stent or bypass operation is required. The significance of the finding, symptoms, anatomy and expected benefit of revascularization need to be assessed in the clinical context.
Questions before accepting a hospital proposal
Clarify whether the planned visit is diagnostic only or may include treatment if a significant lesion is found.
- Is non-invasive testing still needed before angiography?
- Could PCI be performed during the same admission if appropriate?
- What medicines must be continued or adjusted before the procedure?
- How long should I remain near the hospital after discharge?
- What is included in the cost estimate?
