Answer

The following studies are used in the diagnosis and assessment of aortic stenosis:

  • Serum electrolyte levels

  • Cardiac biomarkers

  • Complete blood count

  • B-type natriuretic peptide: May provide incremental prognostic information for predicting symptom onset in asymptomatic patients with severe aortic stenosis [2] ; increased levels appear to be associated with aortic stenosis-related adverse events in asymptomatic severe aortic stenosis [3]

  • Electrocardiography (ECG): Serial ECG can demonstrate the progression of aortic stenosis

  • Chest radiography

  • Echocardiography: Two-dimensional and Doppler

  • Cardiac catheterization: Can be used if clinical findings are inconsistent with echocardiogram results

  • Coronary angiography

  • Radionuclide ventriculography: May provide information on left ventricular function

  • Exercise stress testing: Contraindicated in symptomatic patients with severe aortic stenosis
