What is the prognostic value of high-dose dobutamine stress magnetic resonance imaging (MRI) in patients with left bundle branch block?
The prognostic value of high-dose dobutamine stress magnetic resonance imaging (MRI) in patients with left bundle branch block was examined in a 2010 study by Korosoglou et al. which found that it could reliably predict outcomes in 1493 consecutive patients. Other studies have also looked at the prognostic value of stress myocardial perfusion and late gadolinium enhancement imaging by cardiac magnetic resonance, 64-slice cardiac computed tomography, and exercise and/or dipyridamole hyperemia. Generally, these studies have found that MRI can provide a reliable prognostic value in patients with left bundle branch block.
