Abstract
The prevalence of silent myocardial ischemia (SMI) is more frequent in diabetic patients and is associated with a worse prognosis (1). In order to prevent adverse cardiac events, current guidelines recommend detection of asymptomatic coronary artery disease (CAD) in type 2 diabetic patients with high cardiovascular (CV) risk (2,3). The ECG stress test is recommended but frequently inconclusive in type 2 diabetic patients. This study aimed to compare stress thallium-201 single photon emission computed tomography (SPECT) with dobutamine echocardiography (DE) for the screening of SMI and CAD in type 2 diabetic patients. The study was designed with 55 and 30% anticipated rates of positive SPECT and DE, …
