Implications for acute intervention related to time of hospital arrival in acute myocardial infarction

摘要: The time from onset of symptoms to arrival in the hospital emergency room (ER) was studied 778 patients randomized into a study acute myocardial infarction (AMI) size limitation. Patients at relatively high risk death after AMI (including those with preexisting diabetes mellitus, systemic hypertension or congestive heart failure), women and older arrived significantly later ER than did without these characteristics. A higher mortality rate observed who late, i.e., more 2 hours chest pain, even though hemodynamic compromise (bradycardia, hypotension) tended arrive earlier. difference long-term between early (within pain) late accounted for by baseline differences groups. These may influence effects interventions AMI. In addition, findings have implications education high-risk could benefit most aggressive intervention.
