ST-segment elevation myocardial infarction (STEMI) represents one of the most severe and time-sensitive forms of acute coronary syndrome. It is caused by sudden and complete occlusion of a coronary artery, leading to rapid myocardial ischemia and necrosis. In this setting, timely restoration of coronary blood flow is critical. The concept of door-to-balloon (D2B) time has emerged as a cornerstone quality metric in STEMI care, reflecting the efficiency of hospital systems in delivering reperfusion therapy through primary percutaneous coronary intervention (PCI).
