No time to delay reperfusion: A cross‐sectional study of primary percutaneous coronary intervention times.

Aims and objectives: To establish and report cross‐sectional data of reperfusion times for emergency primary percutaneous coronary interventions (PPCI) and to examine factors associated with times to reperfusion. Background: Rapid coronary reperfusion can salvage myocardial tissue, preserve left ventricular function and reduce mortality. PPCI is the gold standard of management. Researchers have reported on international median reperfusion times, but this is the first Irish study to do so. Methods: This observational, prospective, cross‐sectional study included patients diagnosed with ST‐segment elevation myocardial infarction (STEMI) and admitted for emergency PPCI. Descriptive and inferential statistics were used. The study was ethically approved. We adopted the STROBE guidelines. Results: All patients (N = 133) who met the inclusion criteria were included initially. Of these, 105 (79%) were diagnosed with STEMI and received emergency PPCI. The majority of STEMIs were diagnosed by paramedics and most (67%) were reperfused within 120 min, with a median time of 96 min. The results suggested that younger patients achieved timelier PPCI and source of referral was also significant in that more of those transferred directly to the coronary catheterisation laboratory achieved reperfusion within 120 min, compared with those who presented to the emergency department. Conclusion: A timely reperfusion service is achieved for the majority. Attention is needed in respect of the ageing and those admitted directly to the emergency departments with STEMI. Relevance to clinical practice: Further international research is recommended to compare current reperfusion times against guidelines and to identify areas for improvement. Clinicians should be mindful of the importance of rapid reperfusion and the implications of its delay for patients with STEMI. Those presenting to emergency departments with chest pain should be prioritised. [ABSTRACT FROM AUTHOR]
