What is the prognostic value of myocardial perfusion imaging in patients with known or suspected stable angina pectoris?
Myocardial perfusion imaging (MPI) has a prognostic value in patients with known or suspected stable angina pectoris. Studies have shown that MPI can help identify patients at risk for poor outcomes and can also help guide treatment. Studies have also found that MPI can help predict mortality and major cardiac events, as well as help identify reversible myocardial dysfunction and remodeling in patients with heart failure. Additionally, MPI has been found to predict the outcomes of patients with left bundle branch block, and can help determine the effectiveness of beta-blocker therapy for heart failure patients. Furthermore, MPI can be used to help identify patients with angiographically significant coronary artery disease.
