II. Risk Factors

  1. See Cardiac Risk Factors
  2. See Framingham Score

III. Epidemiology

  1. Chest Pain is the presenting complaint in 1% of ambulatory visits
    1. Unstable Angina and Myocardial Infarction represent <4% of ambulatory Chest Pain presentations
    2. Most common cause for clinic Chest Pain presentations are Chest Wall Pain, GERD and constochondritis
    3. However, cardiac disease is the most common U.S. cause of death; have a high index of suspicion
  2. Acute Myocardial Infarction and Chest Pain are the two most commonly litigated ED Malpractice claims
    1. Brown (2010) Acad Emerg Med 17(5):553-60 +PMID:20536812 [PubMed]

IV. Precautions

  1. No single finding is absolutely pathognomonic nor completely reassuring in Chest Pain presentation
    1. Risk stratification, evaluation and management is based on an overall analysis of all clinical data
    2. Approach should be based on combination of factors
      1. Chest Pain Decision Rules
      2. Exam, ekg and Serum Cardiac Markers
    3. Consider atypical presentations of coronary syndromes in atypical patients
      1. Younger patients with Chest Pain
      2. Women with Chest Pain (see below)
      3. Non-diagnostic initial Electrocardiograms
      4. Atypical symptoms
      5. Rusnak (1989) Ann Emerg Med 18(10): 1029-34 +PMID:2802275 [PubMed]
  2. Myocardial Infarction without Chest Pain occurs in up to 50% of patients
    1. Men: 31% overall (13% under age 45)
    2. Women: 42% overall (20% under age 45)
    3. Mortality is 10-15% for painless MI (contrast with 1-2% for those with Chest Pain)
    4. Canto (2000) JAMA 283(24): 3223-9 [PubMed]
    5. Canto (2012) JAMA 307(8): 813-22 [PubMed]
  3. Cardiac Risk Factors only weakly predict Acute Coronary Syndrome (especially with advancing age)
    1. Age 40-65 years: 2.1 Positive Likelihood Ratio
    2. Age over 65 years: 1.1 Positive Likelihood Ratio
    3. Han (2007) Ann Emerg Med 49(2): 145-52 [PubMed]
  4. Sudden Dyspnea may be only presenting symptom of ACS
    1. Only symptom in up to 14% of patients with MI
  5. Myocardial Infarction often presents with gastrointestinal symptoms
    1. Indigestion or burning pain (23%)
    2. Nausea (60%)
    3. Upper Abdominal Pain (20%)
  6. Esophageal pain often presents with MI type findings
    1. Pain radiates to left arm (11%)
    2. Responds to Nitroglycerin (30-50%)
  7. Relief (or lack of relief) with Nitroglycerin does not predict cause
    1. Non-cardiac pain is often relieved with Nitroglycerin (e.g. Esophageal Spasm)
    2. Cardiac Chest Pain not relieved with Nitroglycerin may be an indication for emergency catheterization (PCI)
    3. Shry (2002) Am J Cardiol 90:1264-6 [PubMed]
  8. Sharp or stabbing Chest Pain may still be cardiac
    1. Up to 22% with sharp Chest Pain have ACS
    2. Several atypical symptoms lower ACS likelihood
    3. ACS may present with Pain fully reproduced with palpation (8-10%)
  9. Intrascapular pain without Chest Pain can represent catastrophic cardiovascular events
    1. Evaluate for Acute Coronary Syndrome and Aortic Dissection
    2. Evaluate for Pulmonary Embolism
    3. Diagnosis of spinal or musculoskeletal causes are after exclusion of intra-thoracic causes
  10. Women often present atypically (e.g. Dyspnea, weakness Nausea, Palpitations, Syncope) with Myocardial Infarctions
    1. Even prior stress testing may have been falsely reasuring
      1. Non-occlusive CAD is twice as common in women
      2. Non-occlusive Plaque may embed within artery wall, erode and cause acute thrombus or vasospasm
    2. Presentations are more similar as men and women age (contrary to prior doctrine)
      1. By age 75 years old, both men and women present without Chest Pain in 50% of cases
    3. Greatest discrepancy between male and female ACS presentations are in the under age 45 cohort
      1. Women with MI under age 45 present without Chest Pain in 20% of cases (contrast with 13% in men)
      2. Spontaneous Coronary Artery Dissection (SCAD) represents 40% of MI in women age under 50 years

      2. Pepine (2015) J Am Coll Cardiol 66(17): 1918-33 +PMID:26493665 [PubMed]
  11. Recent negative stress test does not exclude Acute Coronary Syndrome
    1. Despite JACC 2022 guideline, negative stress test in last year does not exclude Acute Coronary Syndrome
    2. However, normal angiogram or clean Coronary CT Angiography (CCTA) in last 2 years is very reassuring
  12. Under-Served Populations
    1. Black, LatinX, South Asian, Medicaid and Uninsured patients have a higher morbidity and mortality with Chest Pain
    2. Under-served populations receive less aggressive evaluation and management in Chest Pain presentations
