Door-to-Balloon Time and Clinical Outcome of Patients Presenting with ST-Segment Elevation Myocardial Infarction During on and off Hours: a Single Center Study

Our results revealed that neither door-to-balloon time nor off-hours presentation significantly affected mortality rates or complications in pa-tients with STEMI undergoing Primary PCI, with the exception of hypotension being significantly associat-ed with 30-day mortality. Further research is warranted to explore other factors that may influence STEMI outcomes beyond door-to-balloon time and presentation hours. Additionally, investigating the specific rela-tionship between hypotension and 30-day mortality could lead to improved risk stratification and manage-ment strategies for STEMI patients.
