Association of Door-In to Door-Out Time With Reperfusion Delays and Outcomes Among Patients Transferred for Primary Percutaneous Coronary Intervention.

The article discusses a study which examined the proportion of ST-elevation myocardial infarction (STEMI) patients who are transferred with a door-in to door-out (DIDO) time of 30 minutes or less and assessed patient factors linked with delays in DIDO time. It notes that the preferred method of reperfusion for STEMI patients is primary percutaneous coronary intervention (PCI). Results showed that median DIDO time was 68 minutes. Older age, female sex and off-hours presentation were some of the factors associated with a DIDO time greater than 30 minutes. The study also found that only .6% of patients with DIDO times greater than 30 minutes had an absolute contraindication to fibrinolysis.
