Primary percutaneous coronary intervention (PPCI) is preferred for ST-elevation myocardial infarction (STEMI), but delays at non-PPCI hospitals harm patients. Early fibrinolysis with mechanical interventions offers excellent outcomes, advocating for a dual reperfusion strategy.
Area of Science:
- Cardiology
- Emergency Medicine
- Public Health
Background:
- ST-segment elevation myocardial infarction (STEMI) care has shifted towards primary percutaneous coronary intervention (PPCI).
- PPCI demonstrates superior reperfusion compared to fibrinolysis in STEMI patients.
- Most STEMI patients present to hospitals without 24/7 PPCI capabilities, leading to delays.
Purpose of the Study:
- To address the treatment paradox where efforts to improve PPCI lead to delays in other therapies for STEMI.
- To highlight the unfavorable consequences of delayed PPCI in STEMI management.
- To advocate for an integrated dual reperfusion strategy for all STEMI patients.
Main Methods:
- Review of current STEMI treatment guidelines and national care programs.
- Analysis of evidence regarding the outcomes of delayed PPCI versus early fibrinolysis.
- Evaluation of prehospital fibrinolysis combined with mechanical co-interventions.
Main Results:
- Delayed PPCI in STEMI patients presenting to non-PPCI centers often results in denial of timely pharmacologic therapy.
- Recent evidence confirms negative outcomes associated with delayed PPCI.
- Early prehospital fibrinolysis coupled with strategic mechanical interventions shows excellent results.
Conclusions:
- The current approach to STEMI care creates a paradox, delaying beneficial treatments like fibrinolysis.
- An integrated dual reperfusion strategy, combining early fibrinolysis with timely mechanical interventions, is recommended.
- This integrated approach aims to optimize outcomes for all STEMI patients, regardless of initial hospital capabilities.
