Aggressive Measures to Decrease Door to Balloon Time May Increase the Incidence of Unnecessary Cardiac
Insights
Aggressively reducing door-to-balloon time for ST-elevation myocardial infarction (STEMI) may increase false positives and mortality. Careful monitoring is needed to avoid unnecessary procedures in critically ill patients without STEMI.
Area of Science:
- Cardiology
- Emergency Medicine
- Healthcare Quality Improvement
Background:
- Door-to-balloon (DTB) time is a critical metric for ST-segment elevation myocardial infarction (STEMI) care.
- Aggressive reduction of DTB time is a common quality improvement goal.
- Potential adverse effects of overly aggressive DTB time reduction are not fully understood.
Abstract:
Door-to-balloon (DTB) time is an important quality measure for ST-segment myocardial elevation infarction (STEMI). Aggressive measures to reduce DTB time can increase the incidence of false positive-STEMI and may increase mortality in that group. Efforts to reduce DTB time should be monitored systematically to avoid unnecessary procedures especially in critically ill patients who don't have STEMI and may benefit from other appropriate therapies in timely manner. We report two cases where trying to achieve an aggressive DTB time may have led to unwarranted outcomes.
