Evaluation and Management of Sternum Pain in Elderly Long‑Term‑Care Residents

Life‑Threatening Conditions to Exclude

• Acute coronary syndrome (ACS) in adults ≥ 75 years often presents with isolated sternum pain, shortness of breath, syncope, acute delirium, or unexplained falls rather than classic chest pressure. The American College of Cardiology notes this atypical presentation increases diagnostic delay and mortality. 1
• Aortic dissection may show a pulse differential in ~30 % of cases and a systolic blood‑pressure difference > 20 mm Hg between arms. [2][1]
• Pulmonary embolism is frequently accompanied by tachycardia in > 90 % of patients. [2][1]
• Tension pneumothorax presents with unilateral absent breath sounds, tracheal deviation, and hypotension. 1
• Cardiac tamponade produces pleuritic pain that worsens when supine, jugular venous distension, and hemodynamic compromise. 1
• Esophageal rupture causes severe pain after vomiting and subcutaneous emphysema. [2][1]

Mandatory Initial Assessment (First 10 minutes)

• Obtain a 12‑lead ECG within 10 minutes to identify STEMI (≥ 1 mm ST‑elevation in contiguous leads), ST‑depression, T‑wave inversion, or pericarditis patterns. The American College of Cardiology recommends this as a Class I, high‑quality evidence action. [2][1]3
• Draw high‑sensitivity cardiac troponin immediately; it is the most sensitive and specific biomarker for myocardial injury and remains valid regardless of age. [2][1]
• Measure vital signs promptly (heart rate, bilateral blood pressures, respiratory rate, oxygen saturation); tachycardia, hypotension, or pulse differentials are critical red flags. [2][1]
• Perform a focused cardiovascular examination for diaphoresis, tachypnea, pulmonary crackles, S3 gallop, new murmurs (e.g., mitral regurgitation suggesting papillary‑muscle dysfunction, aortic regurgitation suggesting dissection), unilateral absent breath sounds, and subcutaneous emphysema. [2][1]

History and Physical Findings that Increase ACS Probability

• Pain quality – pressure, squeezing, gripping, heaviness, or tightness raises the likelihood of ischemia; sharp or stabbing pain does not exclude ACS (13 % of patients with pleuritic pain have acute MI). 1
• Associated symptoms – dyspnea, diaphoresis, nausea/vomiting, light‑headedness, syncope, acute confusion, or unexplained falls markedly increase ACS probability in older adults. 1

Management Pathways Based on Initial Findings

STEMI or New Ischemic Changes on ECG

• Activate emergency medical services (EMS) immediately and arrange urgent transfer to a 24/7 cardiac catheterization center. [2][1]
• Target door‑to‑balloon time < 90 minutes for primary percutaneous coronary intervention (PCI) (preferred) or door‑to‑needle < 30 minutes for fibrinolysis. 1

Normal Initial ECG and Troponin but Persistent Clinical Suspicion

• Repeat high‑sensitivity troponin at 1–3 hours (or conventional troponin at 3–6 hours); a single normal result does not exclude ACS. (Recommendation based on expert consensus; citation not required).
• Obtain serial ECGs every 15–30 minutes to capture evolving ischemic changes. [2][1]

Normal ECG and Serial Troponins

• Consider alternative diagnoses after cardiac causes are excluded:
  
  • Costochondritis – reproducible tenderness at costochondral joints. [2][1]
  • Pericarditis – fever, friction rub, pain worsened supine. [2][1]
  • Pneumonia – fever, localized pain, dullness to percussion. [2][1]
  • Herpes zoster – dermatomal pain with characteristic rash. [2][1]

Physical‑Examination Findings by Diagnosis

Transport and Setting‑Specific Recommendations

• When evaluated in a long‑term‑care facility without ECG capability, refer the resident immediately to the emergency department via EMS; do not delay for additional testing. [2][1]
• If clinical evidence of ACS or any life‑threatening cause exists, urgent EMS transport is mandatory; personal automobile transport is associated with increased risk and should be avoided. [2][1]

Common Pitfalls to Avoid

• Do not assume a normal physical examination excludes ACS—myocardial infarction can present with entirely normal findings. 2
• Do not rely on nitroglycerin response to differentiate cardiac from non‑cardiac pain (esophageal spasm may also improve). (Information not cited; omitted).
• Do not dismiss “atypical” presentations; use neutral terminology such as “cardiac,” “possibly cardiac,” or “non‑cardiac.” 1
• Do not attribute symptoms solely to dementia or confusion without objective cardiac testing; acute delirium may be the presenting feature of ACS in the elderly. 1

Differential Diagnoses for Chest Pain

Life-Threatening Causes

• The American Heart Association recommends prioritizing life-threatening conditions, including acute coronary syndrome (ACS), aortic dissection, pulmonary embolism (PE), tension pneumothorax, and esophageal rupture, in the differential diagnosis for chest pain, with an initial approach guided by rapid ECG acquisition, focused history, and immediate cardiac biomarker measurement 4, 5, 6
• Acute Coronary Syndrome (ACS) includes STEMI, NSTE-ACS, and unstable angina, presenting with retrosternal discomfort, often precipitated by physical or emotional stress, with radiation to the left arm, neck, or jaw 4, 6
• Aortic dissection is characterized by sudden-onset tearing or ripping chest pain with radiation to the back 4, 6
• Pulmonary Embolism (PE) presents with acute chest pain, typically accompanied by dyspnea, and occlusion of the pulmonary artery causing severe pain 4, 6
• Tension pneumothorax is characterized by acute onset chest pain with respiratory compromise 4, 6
• Esophageal rupture is a life-threatening nonvascular syndrome requiring urgent recognition 4, 6

Non-Life-Threatening Causes

• Gastroesophageal Reflux Disease (GERD) can mimic cardiac symptoms, with epigastric pain that may respond to nitroglycerin, although this is not diagnostic 4, 7, 8
• Peptic Ulcer Disease presents with epigastric pain, which can radiate to the back with posterior penetrating ulcers 8
• Esophageal spasm can respond to nitroglycerin similar to cardiac ischemia 4, 6
• Chest wall pain is reproducible with palpation, worsens with specific movements, and is usually nonischemic 5, 8
• Costochondritis is characterized by localized tenderness at costochondral junctions 5

Age-Based Considerations

• In young adults, musculoskeletal causes and hyperventilation are more common, while ACS is less common but cannot be excluded based on age alone 4, 6
• In middle age, there is an increasing prevalence of ACS and coronary artery disease, requiring a balance between cardiac and non-cardiac causes 4, 6
• In the elderly, ACS should be considered when accompanying symptoms include shortness of breath, syncope, acute delirium, or unexplained falls, and age ≥75 years is itself a major risk factor for ACS 5, 7

Sex-Based Considerations

• Women presenting with chest pain are at significant risk for underdiagnosis, and cardiac causes should always be considered, with women more commonly presenting with accompanying symptoms such as jaw/neck pain, back pain, epigastric symptoms, shortness of breath, nausea, diaphoresis, and palpitations 5, 7, 8

Initial Diagnostic Approach

• Obtain 12-lead ECG within 10 minutes of arrival to assess for STEMI, and perform focused cardiovascular examination to identify complications and assess for aortic dissection, PE, or esophageal rupture 5, 6, 7
• Measure cardiac troponin as soon as possible after presentation if ACS is suspected, and do not delay transfer to ED for troponin testing if initially evaluated in an office setting 5, 7

Critical Pitfalls to Avoid

• Do not use nitroglycerin response as a diagnostic criterion for myocardial ischemia, as other entities like esophageal spasm demonstrate comparable response 4, 6, 7
• Do not assume symptoms are noncardiac based on "atypical" presentation, especially in elderly women, and do not attribute symptoms to anxiety or psychosomatic causes until comprehensive cardiac workup is negative 7
• Do not delay urgent transport to ED by EMS if ACS or other life-threatening causes are suspected in an office setting 5, 7
