Evaluation and Management of Cardiac Ischemia in Women with Normal Coronary CTA
Initial Assessment and Symptom Evaluation
- The American College of Cardiology notes that left arm pain combined with jaw pain is concerning for potential cardiac ischemia, even with a normal CTA, as these are common locations for referred cardiac pain 1
- Women often present with more accompanying symptoms beyond classic chest pain, including jaw and arm pain, which increases the risk of underdiagnosis, according to the American College of Cardiology 2
- At age 61, this female patient is in a demographic where atypical presentations of cardiac ischemia are more common and should be taken seriously, as suggested by the American College of Cardiology 2, 3
Diagnostic Testing and Evaluation
- A normal coronary CTA falls into CAD-RADS 0-2 category, indicating minimal or no obstructive coronary disease, as defined by the Journal of the American College of Cardiology 4, 5
- The European Heart Journal recommends considering microvascular coronary disease and coronary vasospasm in patients with normal CTA, particularly in women 6
- Stress testing with imaging, such as stress echocardiography or nuclear stress test, can evaluate for ischemia despite normal coronary anatomy, as recommended by the American College of Cardiology 1, 7
- Cardiovascular Magnetic Resonance (CMR) can help identify other causes of symptoms, such as myocarditis or Takotsubo syndrome, and has the ability to identify underlying causes in up to 87% of patients with MINOCA, according to the European Heart Journal and Circulation 6, 7
Management and Treatment
- The European Heart Journal suggests initiating empiric anti-anginal therapy if symptoms are highly suspicious for cardiac ischemia, even with normal coronary arteries 6, 7
- Addressing cardiovascular risk factors aggressively, such as hypertension, diabetes, and dyslipidemia, is crucial, as recommended by the American College of Cardiology and Circulation 3, 7
- Low-dose aspirin should be considered for primary prevention if 10-year risk of coronary heart disease is ≥10%, according to the American College of Cardiology 3
