Shorter Door-To-Balloon ST-Elevation Myocardial Infarction Time: Should There Be a Minimum Limit?

Area of Science:

• Cardiology
• Emergency Medicine
• Health Services Research

Background:

• ST-elevation myocardial infarction (STEMI) requires rapid reperfusion to minimize myocardial damage and mortality.
• Door-to-balloon (DTB) time, the interval from patient arrival to percutaneous coronary intervention, is a key quality indicator for STEMI care.
• Existing literature links longer DTB times to increased mortality.

Purpose of the Study:

• To review the relationship between DTB time and mortality in STEMI patients.
• To discuss the established guidelines for DTB time.
• To explore the potential risks of reducing DTB time beyond current recommendations.

Main Methods:

• Literature review of studies examining DTB time and mortality in STEMI.
• Analysis of current clinical guidelines for DTB time.
• Discussion of the implications of overly aggressive DTB time reduction.

Main Results:

• Longer DTB times are associated with higher mortality rates in STEMI.
• Current guidelines recommend a DTB time of less than 90 minutes.
• Reducing DTB time beyond recommended thresholds has not demonstrated improved mortality and may increase risks.

Conclusions:

• While timely reperfusion is critical in STEMI, excessively shortening DTB time may not further reduce mortality.
• Potential harms of overly aggressive DTB reduction include unnecessary interventions and delayed diagnosis of alternative conditions.
• Adherence to current DTB guidelines is recommended, balancing speed with appropriate patient evaluation.
