Predicting treatment outcomes by door-to-device time and baseline characteristics in STEMI patients undergoing PPCI: a cross-sectional study in southern Iran.

While baseline characteristics showed minimal impact, DTD time significantly predicted worse outcomes, including prolonged CCU stays, reduced LVEF, and myocardial injury. These findings emphasize the critical importance of reducing DTD time (<60 minutes) through optimized emergency protocols to improve STEMI management outcomes.
