Door-to-balloon time and the determining factors in a tertiary cardiac center in Nepal.

Background: Door-to-balloon (DTB) time of 90 min during primary angioplasty is considered as the benchmark duration. Shorter DTB time is preferable, and longer duration can have poor clinical outcomes.

Methods: A cross-sectional observational study of three months in Shahid Gangalal National Heart Center was conducted in which all patients undergoing primary angioplasty were included.

Prehospital Events in ST- Elevation Myocardial Infarction Undergoing Primary Angioplasty.

Introduction: Pre-hospital delay includes time from onset of symptoms of myocardial infarction till arrival to emergency room of the hospital. This defines time from symptom onset to first medical contact and first medical contact to emergency room. This study aims to study the prehospital events and determining factors in patients undergoing primary angioplasty.
