Abstract

Background
Primary percutaneous coronary intervention (PCI) is the preferred reperfusion strategy in patients with STelevation myocardial infarction (STEMI) within 12 hours of symptom onset, provided it can be performed
expeditiously (i.e., 120 min from STEMI diagnosis) by an experienced team. A professional team includes
not only interventional cardiologists but also skilled support staff. Lower mortality rates among patients
undergoing primary PCI are observed in centres with a high volume of PCI procedures. In addition, door-toballoon time became an indicator of the quality of care in STEMI patients treated with primary PCI.
Objectives
To evaluate the impact of door-to-balloon time delay on cardiovascular outcomes in patients with STEMI.
Methods
Prospective cohort study of door-to-balloon time (DTB) delay and adverse cardiovascular outcomes in patients
with STEMI treated with primary PCI.
Results
About 65% (n=131) of patients were free from adverse outcomes with a Mean door-to-balloon time of 92
minutes vs adverse effects (left ventricular dysfunction or angina) happened in 26% (n=52) with a mean doorto-balloon time of 168 minutes and death in 8% (n=16) with a mean time of 114 minutes (P=0.001). Similar
results were found with symptom onset-to-balloon time, no adverse outcomes with a mean symptom onset-toballoon time of 11.98 hours compared to 22 hours with adverse effects and deaths;( p=0.004.)
Conclusion
Any delay in door-to-balloon time or symptom onset-to-balloon time in patients with ST-elevation myocardial
infarction is associated with higher morbidity and mortality rate.
