Emergency department evaluation of the chest pain patient
1Department of Emergency Medicine, Vanderbilt University Hospital, Vanderbilt University Medical Center, Nashville, Tennessee, USA.
Insights
Emergency physicians should suspect myocardial ischemia in patients with undiagnosed chest pain. Further testing is recommended for most patients to minimize the risk of missed myocardial infarction.
Area of Science:
- Emergency Medicine
- Cardiology
Background:
- Chest pain is a common emergency department presentation.
- Accurate risk stratification is crucial for diagnosing myocardial ischemia.
- Subjective assessment alone is insufficient for ruling out myocardial infarction.
Purpose of the Study:
- To emphasize the importance of high clinical suspicion for myocardial ischemia.
- To outline the emergency physician's role in risk assessment and diagnostic testing.
- To advocate for further testing in most patients presenting with chest pain.
Main Methods:
- Clinical assessment of patients presenting with chest pain.
- Risk stratification to determine the likelihood of myocardial ischemia.
- Selection of appropriate diagnostic studies.
Main Results:
- Subjective evaluation cannot definitively rule out myocardial ischemia or infarction.
- A significant proportion of patients require further diagnostic evaluation.
- Testing is advised for all risk categories except the very low-risk group.
Conclusions:
- Emergency physicians must maintain a high index of suspicion for myocardial ischemia.
- Objective diagnostic studies are essential for accurate diagnosis and management.
- Aggressive management of acute ischemia or infarction is critical.
Abstract:
The emergency physician must have a high degree of suspicion for myocardial ischemia in patients presenting with no obvious for their chest pain. The role of the emergency physician is to determine a relative risk for each patient and to order the appropriate studies to minimize the risk of missed myocardial infarction as well as to recognize acute ischemia or infarction and manage it aggressively. It is not possible to rule out myocardial ischemia or infarction subjectively. It is the opinion of these authors that some form of further testing should be performed on patients in all categories, except those determined to be at very low risk.
