Effect of initial heart rate on cardiac troponin and ejection fraction in patients with non-ST segment elevation myocardial infarction.

Background: Increased heart rate has shown to be associated with adverse cardiovascular outcomes. This aim of this study was to find the association of troponin level and ejection fraction (EF) with triage heart rate in patients with non-ST elevation myocardial infarction (NSTEMI). It was hypothesized that heart rate at triage will be independently associated with higher troponin level and lower EF after NSTEMI.

Role of dexamethasone in the prevention of migraine recurrence in the acute care setting: a review.

Patients with migraine headaches are commonly encountered by clinicians both in the clinic and in the emergency department. Migraines impose a significant financial burden on patients, caregivers, and society. Up to 49% of patients treated acutely for migraine headache will have a recurrence within 72 hours.
