Management of Chest Pain and Fatigue After Normal Cardiology Workup

Immediate Reassessment for Life-Threatening Non-Cardiac Causes

The European Society of Cardiology recommends obtaining a chest X-ray to evaluate for pneumothorax, pleural effusion, pneumonia, or intrathoracic tumors 3
Consider pulmonary embolism if risk factors are present, requiring specific evaluation with D-dimer and/or CT pulmonary angiography, as suggested by the European Heart Journal 1
Evaluate for aortic dissection if pain is severe, tearing, or radiates to the back, particularly in patients with hypertension, according to the European Heart Journal 1
Assess for acute pericarditis with careful auscultation for friction rub and review of ECG for diffuse ST elevation, as recommended by the European Heart Journal 1

The American College of Cardiology recommends measuring cardiac troponins at presentation and repeated 8-12 hours after symptom onset, as a single negative troponin is insufficient 4
Serial ECGs should be performed if symptoms persist, as initial ECG can be normal in over 50% of patients with chronic stable angina, according to the American Heart Association 6
Left ventricular function should be assessed with echocardiography, as LV dysfunction profoundly affects prognosis and management, as stated by the American Heart Association 6
Stress testing should be completed before discharge or scheduled as outpatient with specific precautionary instructions, as recommended by the American Heart Association 6

Microvascular angina symptoms can occur with normal epicardial coronaries, more common in women, according to the European Society of Cardiology 2
Pericarditis may have been missed if friction rub was transient, as noted by the European Heart Journal 1

Thyroid dysfunction, particularly hyperthyroidism, must be actively excluded as it commonly causes chest pain and fatigue, according to the European Thyroid Association 5
Measure TSH, free T4, and free T3 urgently if cardiac symptoms present, as TSH has >98% sensitivity, as recommended by the European Thyroid Association 5
Hyperthyroidism causes "functional angina" by increasing myocardial oxygen demand beyond supply capacity, even with normal coronary arteries, as stated by the European Thyroid Association 5
Start beta-blockers immediately if hyperthyroidism is confirmed, as this is the cornerstone of acute cardiac symptom management, according to the European Thyroid Association 5

Palpate chest wall for reproducible tenderness suggesting costochondritis or musculoskeletal pain, as recommended by the European Society of Cardiology 2
Consider anxiety/panic disorder, but only after organic causes are excluded, according to the European Heart Journal 1

Schedule outpatient stress testing within 72 hours if not performed during initial evaluation, as recommended by the American Heart Association 6
Prescribe precautionary anti-ischemic treatment while awaiting stress test, according to the American Heart Association 6
Provide explicit return precautions, such as calling 9-1-1 if chest pain lasts >5 minutes or worsens despite one nitroglycerin dose, as recommended by the American Heart Association 7
Notify primary care physician with test results and ensure appointment within 72 hours, as stated by the American Heart Association 6

Do not rely on nitroglycerin response as a diagnostic criterion, as other conditions may respond similarly, according to the European Society of Cardiology 2
Do not discharge based on single negative troponin, as repeat at 8-12 hours is mandatory, as recommended by the American College of Cardiology 4
Do not assume normal resting ECG excludes ischemia, as over 50% of stable angina patients have normal resting ECGs, according to the American Heart Association 5
Do not overlook atypical presentations in women, elderly, and diabetics who may present with fatigue and dyspnea rather than classic chest pain, as noted by the European Society of Cardiology 2
