Prognostic value of cardiac autonomic neuropathy independent and incremental to perfusion defects in patients with diabetes and suspected coronary artery disease.

We investigated the prognostic value of cardiac autonomic neuropathy (CAN) in relation to perfusion defects in 146 diabetic patients with suspected coronary artery disease. Perfusion defects and CAN were significant univariate predictors of death (p=0.05 and p<0.
