Acute coronary syndromes in the emergency department: diagnostic characteristics, tests, and challenges

Area of Science:

• Cardiology
• Emergency Medicine
• Public Health

Background:

• Acute coronary syndromes (ACSs) are a significant public health concern.
• Failure to diagnose ACSs, such as acute myocardial infarction (AMI) and unstable angina pectoris (UAP), in the emergency department (ED) persists.
• Understanding coronary artery disease pathophysiology has led to a unifying hypothesis for ACSs involving plaque rupture and thrombosis.

Purpose of the Study:

• To review the current diagnostic approaches for ACSs in emergency settings.
• To identify factors contributing to missed diagnoses of ACSs.
• To provide an overview of the diagnostic continuum of ACSs.

Main Methods:

• Literature review of state-of-the-art diagnostic methods for ACSs.
• Analysis of factors contributing to diagnostic errors in the emergency department.
• Synthesis of current understanding of ACS pathophysiology.

Main Results:

• The article reviews current diagnostic techniques for ACSs in the ED.
• It discusses the continuum of ACSs, from stable lesions to plaque rupture and thrombosis.
• Reasons for infrequent missed diagnoses are explored.

Conclusions:

• Despite advances, diagnosing ACSs in the ED remains critical.
• Understanding plaque rupture and thrombosis is key to diagnosing ACSs.
• Infrequent missed diagnoses highlight the need for continued vigilance and improved diagnostic strategies.
