Do you believe medical testing that prevents unnecessary procedures improves patient safety?
The AIR-STEMI trial found that using physiology-guided revascularization reduces major cardiovascular events compared to traditional angiography-guided approaches in patients with heart attacks. These findings, which may shift standard practice, track 1,823 patients over a median of 17.9 months.
Why it matters
This approach helps cardiologists identify and treat only the most significant blockages in heart attack patients rather than every vessel that looks narrowed on an angiogram. By avoiding unnecessary procedures, this strategy can lower risks for patients while ensuring critical vessels receive necessary attention.
The randomized clinical trial followed 1,823 patients for a median of 17.9 months, finding a 35% relative risk reduction in major cardiovascular events with physiology-guided care. It is currently unclear how these results translate to long-term survival beyond the study duration.

The details
Physiology-guided revascularization utilizes an angiography-derived fractional flow reserve measurement to assess the severity of non-culprit artery blockages. Vessels with a value of 0.80 or less are treated, while those exceeding this threshold are deferred. This process limits invasive procedures; in the trial, only 51.9% of non-culprit vessels were treated in the physiology-guided group compared to 94.9% in the angiography-guided group.

Health Landscape
This development follows an ongoing shift at the ESC Congress 2026 toward replacing traditional angiography-only assessment with more precise physiological measures. The strategy signals a departure from uniform intervention in multivessel disease toward personalized, function-based treatment.
If you or a loved one are undergoing treatment for a heart attack involving multiple blocked arteries, you may want to ask your cardiologist if physiological testing is appropriate for your specific case. This approach is intended to minimize unnecessary vessel interventions while still addressing the most clinically important risks.
The takeaway
Physiology-guided intervention offers a more targeted approach to treating secondary artery blockages during heart attacks, resulting in fewer procedures. Discuss the role of physiological assessment, such as fractional flow reserve, with your cardiologist to understand if it is right for your heart health.
