Emergency medical service utilization and door-to-balloon time for HIV-infected individuals with ST-elevation myocardial infarction

摘要

Rapid coronary reperfusion is associated with improved survival among patients presenting with an ST-elevation myocardial infarction (STEMI) [1], Previous research has demonstrated that emergency medical service (EMS) utilization can facilitate rapid revascularization [2]. Because of this, professional guidelines have identified EMS utilization and a rapid door-to-balloon time (DTBt) as quality metrics related to improved outcomes [3]. The utilization of ambulance services and the attainment of the target revascularization times, however, have not yet been evaluated in subjects infected with human immunodeficiency virus (HIV). Previous research has demonstrated that HPV-infected individuals presenting with acute coronary syndromes (ACS) have fewer symptoms than uninfected individuals [4]. Furthermore, HFV-infected subjects may be susceptible to disparities in access to appropriate cardiopulmonary care [5]. With this in mind, we hypothesized that HrV-infected patients would be less likely to utilize EMS and achieve a DTBt less than 90 min when presenting with STEMI.
