History of Present Illness for Chest Pain in the Emergency Department

Chief Complaint

"Chest pain"

History of Present Illness

Pain Characteristics (OPQRST Format)

Onset:

  • Exact time symptoms began (gradual onset over minutes suggests ACS; sudden "ripping" onset suggests aortic dissection) 1
  • Activity at time of onset (exertion, rest, emotional stress, post-meal) 1
  • Whether pain awakened patient from sleep 1

Provocation/Palliation:

  • Exacerbated by: physical exertion, emotional stress, deep breathing, position changes, palpation of chest wall 1
  • Relieved by: rest, nitroglycerin (though response is NOT diagnostic of cardiac ischemia), antacids, position changes 1, 2
  • Any self-treatment attempted and response 1

Quality:

  • High probability descriptors for ischemia: pressure, dull, squeezing, aching, gripping, burning, heaviness, tightness, retrosternal discomfort 1
  • Lower probability descriptors: stabbing, sharp, fleeting (seconds duration), pleuritic, shifting 1
  • Avoid using term "atypical" as it can be misinterpreted as benign 1

Region/Radiation:

  • Location: retrosternal, left-sided, central (higher probability); right-sided, localized to small area (lower probability) 1
  • Radiation patterns: left arm, jaw, neck, shoulders, back (upper back suggests aortic dissection), epigastrium 1, 3
  • Pain below umbilicus or hip is unlikely ischemic 1

Severity:

  • Numeric pain scale (0-10) 1
  • "Worst chest pain of my life" suggests acute aortic syndrome 1, 3
  • Functional impact on activities 1

Timing:

  • Duration of current episode (fleeting seconds unlikely ischemic; gradual build over minutes suggests ACS) 1
  • Pattern: constant vs. intermittent, frequency of episodes, any recent change in pattern (crescendo pattern) 1
  • Total time from symptom onset to presentation 1

Associated Symptoms

Cardiac-related symptoms:

  • Dyspnea or shortness of breath (particularly important in women and elderly) 1, 3, 4
  • Diaphoresis 1, 3, 2
  • Nausea/vomiting (more common in women with ACS) 1, 3, 4
  • Lightheadedness or dizziness 1, 3
  • Syncope or near-syncope (consider in elderly ≥75 years) 1, 4
  • Palpitations 3, 2
  • Arm pain, jaw pain, or bilateral hand numbness (particularly in women) 3, 4
  • Epigastric discomfort or "heartburn" with acute onset 3
  • Fatigue (more common in women) 3, 4

Non-cardiac symptoms:

  • Cough, hemoptysis (consider PE, pneumonia) 3, 4
  • Fever, chills (infectious etiology) 4
  • Acute delirium or confusion (particularly in elderly ≥75 years with ACS) 1, 4
  • Unexplained fall (consider in elderly ≥75 years) 1

Pertinent Past Medical History

Cardiovascular Risk Factors

  • Coronary artery disease: prior MI, prior PCI/stents, prior CABG 1, 3, 2
  • Diabetes mellitus (high-risk population even with minimal symptoms) 3, 4
  • Hypertension 1, 3, 2
  • Hyperlipidemia 1, 3, 2
  • Current or former tobacco use (quantify pack-years) 1, 3, 2
  • Chronic kidney disease or renal insufficiency (high-risk population) 4
  • Peripheral arterial disease 1
  • Cerebrovascular disease/prior stroke 1
  • Heart failure 1, 2
  • Atrial fibrillation 1

Other Relevant Conditions

  • Aortic valve disease (bicuspid aortic valve, known aortic dilation—risk for dissection) 1, 3
  • Hypertrophic cardiomyopathy 5
  • Severe anemia 5
  • Dementia (high-risk population for atypical ACS presentation) 4
  • Pulmonary disease: COPD, asthma, prior PE 3, 4
  • Gastroesophageal reflux disease 2, 6
  • Anxiety or panic disorder 2, 6
  • Malignancy (PE risk factor) 4
  • Hypercoagulable state (PE risk factor) 4

Current Medications

  • Antiplatelet agents: aspirin, clopidogrel, ticagrelor, prasugrel 3
  • Anticoagulants: warfarin, DOACs, heparin 3, 4
  • Cardiac medications: beta-blockers, ACE inhibitors, ARBs, statins, nitrates 3, 5
  • Diuretics 5
  • Antidepressants (tricyclics can cause dry mouth affecting sublingual nitroglycerin dissolution) 5
  • Medications for erectile dysfunction: sildenafil, tadalafil, vardenafil (contraindicated with nitrates) 5
  • Guanylate cyclase stimulators: riociguat (contraindicated with nitrates) 5
  • Ergotamine or migraine medications (can precipitate angina) 5
  • Recent medication changes or non-compliance 1

Allergies

  • Drug allergies: particularly aspirin, heparin, contrast dye 3
  • Nature of reaction (true allergy vs. intolerance) 3

Past Surgical History

  • Prior CABG (dates, number of grafts) 1, 3
  • Prior cardiac valve surgery 1
  • Recent surgery of any type (PE risk factor) 4
  • Vascular surgery 1

Past Procedural History

  • Prior PCI/stenting (dates, vessels treated, stent type) 1, 3
  • Prior cardiac catheterization (dates, findings) 1, 7
  • Prior stress testing (type, date, results) 1, 7, 6
  • Prior echocardiography (findings, ejection fraction) 1

Recent Hospitalizations

  • Recent admission for chest pain, ACS, or heart failure 1
  • Recent immobilization or prolonged bed rest (PE risk factor) 4
  • Recent procedures or surgeries (PE risk factor) 4

Family History

  • Premature coronary artery disease (male first-degree relative <55 years, female first-degree relative <65 years) 1, 3, 2
  • Sudden cardiac death in family members 1
  • Familial hyperlipidemia 1
  • Connective tissue disorders (Marfan syndrome, Ehlers-Danlos—aortic dissection risk) 3

Social History

  • Tobacco use: current, former (pack-years), recent cessation 1, 3, 2
  • Alcohol use: quantity, frequency (can potentiate hypotension with nitroglycerin) 5
  • Illicit drug use: particularly cocaine, methamphetamine (ACS risk) 1
  • Occupational exposures: industrial nitrates (tolerance and withdrawal risk) 5
  • Exercise tolerance and recent changes 1
  • Ability to perform activities of daily living 1
  • Recent long-distance travel or prolonged sitting (PE risk factor) 4

Critical Documentation Note: In women presenting with chest pain, specifically document presence or absence of accompanying symptoms more common in female ACS patients: nausea, fatigue, dyspnea, jaw pain, and epigastric discomfort, as women are at risk for underdiagnosis 1, 3, 4. In patients ≥75 years, document presence or absence of atypical presentations including isolated dyspnea, syncope, acute delirium, or unexplained falls 1, 4.
