Diagnosis and Management of Chest Pain at Rest in Young People

Key Diagnostic Considerations

The American Heart Association recommends that young individuals presenting with chest pain at rest be evaluated for acute coronary syndrome (ACS), as this pattern specifically indicates possible ACS 1, 2
Musculoskeletal chest pain is the most frequent cause in young patients, characterized by positional pain, reproducibility with palpation or movement, sharp or stabbing quality, and pleuritic features 2, 3
The American College of Cardiology suggests that chest pain at rest specifically raises concern for ACS, as occurrence at rest or with minimal exertion is a defining feature of unstable angina and acute coronary syndrome 1, 2, 4
High-risk features requiring immediate evaluation include prolonged rest pain (>20 minutes) 4, accelerating tempo of symptoms 5, and recent onset of severe symptoms (new CCS Class III or IV angina) 4

The European Society of Cardiology recommends considering anomalous coronary arteries in young males with exertional chest pain or syncope, unexplained QRS or ST-T wave changes, and history of symptoms during or after physical activity 6, 5
Myocardial bridging can cause myocardial ischemia and ventricular arrhythmias, and usually responds to beta-blockers 6, 5

The American Heart Association recommends obtaining a 12-lead ECG within 10 minutes of presentation for any suspected cardiac etiology, and measuring cardiac troponin levels to rule out myocardial injury 3
Prolonged rest pain >20 minutes is a high-risk feature requiring admission 4

Young women (≤55 years) are equally likely to present with chest pain as men, and are more likely to report ≥3 associated symptoms, including epigastric symptoms, palpitations, jaw/neck/arm pain 7, 8
The American College of Cardiology suggests that young women with chest pain should always be considered for potential cardiac causes, due to a higher risk of underdiagnosis 5
Young men with exertional symptoms should be considered for anomalous coronary arteries, and coronary angiography is indicated even with negative exercise test in those surviving cardiac arrest 6

For young patients with chest pain at rest and no high-risk features, the American College of Cardiology recommends coronary CT angiography (CCTA) as a diagnostic tool, with excellent negative predictive value (approaching 100%) for excluding coronary artery disease 3
For young patients with high-risk features, urgent transfer to emergency department, ECG within 10 minutes, and immediate cardiac troponin measurement are recommended, with identical management as NSTEMI until troponin results available 4, 3
