What is the preferred timing for door-to-balloon time in STEMI treatment?

The preferred timing for door-to-balloon time in the treatment of ST-elevation myocardial infarction (STEMI) is 90 minutes. This guideline is based on evidence showing that faster intervention leads to improved outcomes for patients experiencing a STEMI, as it minimizes myocardial damage and reduces mortality rates.

Achieving this 90-minute goal requires a well-coordinated response from the emergency medical services and hospital system, facilitating rapid diagnostic procedures, timely administration of antiplatelet therapy, and swift transfer to the catheterization lab for percutaneous coronary intervention (PCI).

While shorter times can be beneficial, 90 minutes is the standard that has been endorsed by major cardiovascular guidelines, balancing the need for speed with realistic logistical constraints in clinical practice. Delays beyond this time frame can lead to worsening patient outcomes, increasing the risk of complications and reducing the potential for recovery.
