This clinical policy from the American College of Emergency Physicians addresses key issues in the evaluation and management of patients with suspected non-ST-elevation acute coronary syndromes. A writing subcommittee conducted a systematic review of the literature to derive evidence-based recommendations to answer the following clinical questions: (1) In adult patients without evidence of ST-elevation acute coronary syndrome, can initial risk stratification be used to predict a low rate of 30-day major adverse cardiac events? (2) In adult patients with suspected acute non-ST-elevation acute coronary syndrome, can troponin testing within 3 hours of emergency department presentation be used to predict a low rate of 30-day major adverse cardiac events? (3) In adult patients with suspected non-ST-elevation acute coronary syndrome in whom acute myocardial infarction has been excluded, does further diagnostic testing (eg, provocative, stress test, computed tomography angiography) for acute coronary syndrome prior to discharge reduce 30-day major adverse cardiac events? (4) Should adult patients with acute non-ST-elevation myocardial infarction receive immediate antiplatelet therapy in addition to aspirin to reduce 30-day major adverse cardiac events? Evidence was graded and recommendations were made based on the strength of the available data.

Observational Study
The Characteristics and Outcomes of Patients Who Make an Emergency Department Visit for Hypertension After Use of a Home or Pharmacy Blood Pressure Device.
Emergency department (ED) visits for hypertension are rapidly increasing. Hypertension guidelines began recommending use of self-measurement blood pressure (BP) devices in the early 2000s, which could be contributing to the increase. We aim to examine the proportion of ED visits for hypertension that occurred after a BP measurement with a self-measuring device, and the associated outcomes. ⋯ In this study, half of patients with an ED visit that was primarily for hypertension presented after elevated readings on self-measurement devices. Only 3% of these patients were admitted to the hospital.

Studies are divided on the short-term association of air pollution with stroke. Singapore is exposed to seasonal transboundary haze. We aim to investigate the association between air pollution and stroke incidence in Singapore. ⋯ We found a short-term elevated risk of ischemic stroke after exposure to air pollution. These findings have public health implications for stroke prevention and emergency health services delivery.
