Immediate Coronary Angiography Does Not Improve Survival After Cardiac Arrest, Study Shows

1w ago September 6, 2026 1 min read 📰 Medical Xpress
📋 Key Takeaway

The DISCO trial found that immediate coronary angiography does not enhance 30-day survival rates in patients without ST-segment elevation after out-of-hospital cardiac arrest. This study was presented at the ESC Congress 2026, highlighting important findings in cardiac care. The implications for Iran are significant as they may influence medical practices and emergency response protocols.

🔍 Quick Context Guide
💡 Bottom Line: The DISCO trial suggests that immediate coronary angiography may not be necessary for certain cardiac arrest patients, prompting a reevaluation of emergency treatment strategies.

👥 Key Players

ESC Congress MENTIONED
Medical Conference Organizer
"The ESC Congress is a major event for cardiology professionals, influencing practices and guidelines in cardiac care globally, including in Iran."
DISCO trial researchers MENTIONED
Conductors of the study
"Their findings can reshape treatment protocols for cardiac arrest patients, impacting emergency medical services in Iran."

📰 What Happened

A study presented at the ESC Congress 2026 found that immediate coronary angiography does not improve survival rates after out-of-hospital cardiac arrest in patients without ST-segment elevation. This challenges previous assumptions about emergency cardiac care.

  • The DISCO trial specifically focused on patients without ST-segment elevation on ECG.
  • The study compared immediate angiography with a deferred approach regarding 30-day survival rates.

💡 Why It Matters

🇮🇷 For Iran: This study could lead to changes in emergency response protocols in Iran, potentially affecting how cardiac arrest cases are handled.
🌍 Regional: Improved understanding of cardiac care can enhance regional healthcare standards and emergency response systems.
🌐 International: The findings may prompt reevaluation of cardiac care protocols in various countries, influencing global medical practices.

📚 Background

Coronary angiography is a procedure used to visualize the heart's arteries, and its role in emergency care for cardiac arrest has been debated. Understanding when to use it can significantly impact patient outcomes.

The information is derived from a scientific presentation, which typically aims to provide objective findings based on research.

Immediate coronary angiography did not improve 30-day survival compared with a deferred strategy in patients without ST-segment elevation on an ECG after out-of-hospital cardiac arrest. These were the main findings of the DISCO trial and a meta-analysis presented in a Hot Line session today at ESC Congress 2026.
