Optimizing door-to-balloon times for STEMI interventions - Results from the SINCERE database

Area of Science:

• Cardiology
• Interventional Cardiology
• Public Health

Background:

• Primary angioplasty significantly reduces mortality and enhances long-term outcomes in ST-elevation myocardial infarction (STEMI) patients.
• Timely intervention is crucial, with door-to-balloon (D2B) times ideally under 90 minutes for optimal effectiveness.

Purpose of the Study:

• To evaluate the feasibility and success rates of primary percutaneous coronary intervention (PCI) with short D2B times in community hospitals.
• To assess the efficacy of standardized techniques in achieving rapid reperfusion for STEMI patients outside of specialized centers.

Main Methods:

• A retrospective analysis of 420 STEMI interventions performed between January 2005 and the present.
• Data were collected from the SINCERE (Single INdividual Community Experience REgistry) database, encompassing procedures at 5 community hospitals by a single experienced operator.

Main Results:

• The median D2B time was 78 minutes, with 85.2% of procedures achieving D2B times less than 90 minutes.
• The median procedure time from local anesthesia to recanalization was 13 minutes.
• Overall procedural success rate was 95%, evidenced by chest pain relief, significant ST-segment resolution (>70%), TIMI 3 flow, and Myocardial Perfusion Grade 3.

Conclusions:

• Standardized techniques enable high success rates and predictable short D2B times for primary PCI in community hospital settings.
• This approach demonstrates that rapid reperfusion therapy for STEMI can be effectively implemented in diverse clinical environments.
