Overview

About

Acute chest pain is one of the most common and challenging complaints encountered in primary care, with causes ranging from benign musculoskeletal conditions to life-threatening cardiac emergencies. A key clinical question in the initial evaluation is whether the pain represents angina due to coronary artery disease (CAD) or a non-cardiac etiology. Distinguishing between these possibilities is crucial, as missing a diagnosis of acute coronary syndrome (ACS) can have devastating consequences, while over-testing or unnecessary referrals can lead to increased healthcare costs and patient anxiety.

The initial assessment begins with a focused history, as the nature, location, onset, duration, and associated symptoms of chest pain provide key diagnostic clues. A thorough review of risk factors is essential for risk stratification. The physical examination helps further refine the differential diagnosis. Electrocardiography (ECG) is the first-line diagnostic tool in the outpatient setting, helping identify acute ischemic changes, arrhythmias, pericarditis, or other structural abnormalities. Patients with high-risk features should be urgently referred to the emergency department (ED) or cardiology for further evaluation. Conversely, patients with low-risk profiles may be managed conservatively with outpatient follow-up, lifestyle counseling, and targeted therapy based on the suspected etiology.

Ultimately, the primary care provider’s role is to rapidly differentiate between benign and life-threatening conditions, ensuring safe and efficient care while minimizing unnecessary hospital referrals. Given the complexity of chest pain presentations, an integrated approach combining clinical acumen, structured risk stratification, and judicious use of diagnostic tools is essential to optimize patient outcomes in the outpatient setting.

This lecture will provide a systematic approach to the evaluation of chest pain in primary care, with an emphasis on recognizing angina suggestive of coronary artery disease by using history-taking, physical examination, risk stratification, appropriate diagnostic testing and timely referral.

Learning outcomes

At the end of this learning activity, participants should be able to:

  • Recognize the importance of timely and accurate evaluation of acute chest pain in primary care setting.
  • Differentiate between angina, cardiac, and non-cardiac causes of chest pain based on clinical presentation.
  • Identify red flags that indicate potentially life-threatening conditions requiring immediate intervention.
  • Conduct a structured history and physical examination to narrow down the differential diagnosis.
  • Perform basic diagnostic tools such as electrocardiogram (ECG) and validated clinical decision rules when warranted.
  • Determine when to refer to emergency care in patients presenting with acute chest pain.
