Official Title

Utility of Exercise-induced NT-pro-brain Natriuretic Peptide Levels in Predicting Prognosis in Asymptomatic Aortic Stenosis

Brief Summary

      One hundred patients with moderate to severe asymptomatic aortic stenosis (AS) will be asked
      to exercise on a treadmill. NT-pro-BNP levels will be drawn before and after exercise.
      Changes in NT-pro-BNP levels will be correlated to outcomes at one year. In the pilot phase
      an additional 10 control subjects without AS will be enrolled to document the control
      response of NT-pro-BNP elevations with exercise.

Study Type

Interventional

Primary Outcome
