What is the prognostic value of pharmacologic stress echocardiography in patients with left bundle branch block?
According to a study by Cortigiani et al. (2001), pharmacologic stress echocardiography has been shown to be a useful tool for predicting prognosis in patients with left bundle branch block. The study found that those with left bundle branch block who underwent pharmacologic stress echocardiography had a higher risk of death in the long-term. This suggests that pharmacologic stress echocardiography can be a valuable tool for prognostic stratification in patients with left bundle branch block.
