BACKGROUND Artificial neural networks have successfully been applied for automated interpretation of myocardial perfusion images. So far the networks have used data from the myocardial perfusion images only. The purpose of this study was to investigate whether the automated interpretation of myocardial perfusion images with the use of artificial neural networks was improved if clinical data wer...
UNLABELLED This study was designed to assess the prognostic value of stress myocardial perfusion SPECT with electrocardiographic (ECG) gating in patients undergoing noncardiac surgical treatment. METHODS The study included 481 consecutive patients who underwent noncardiac surgery and had been referred for preoperative myocardial perfusion scintigraphy. Myocardial scintigraphy used (99m)Tc-lab...
Incessant ventricular tachycardia and long-standing ectopic beats lead to tachycardia-induced cardiomyopathy. Catheter ablation eliminates ventricular tachycardia and reverses left ventricular (LV) dysfunction. 201-Thallium ((201)Tl) scintigraphy demonstrates perfusion defects with ischemic cardiomyopathy. Reversible perfusion defects are observed even in non-ischemic cardiomyopathy, related to...
Objective: The risk of cardiac death in diabetic patients is 3 times more than non-diabetics. But it is not determined who need cardiac screening. About 41% of diabetic patients with silent ischemia are missed. the carotid intima-media thickness (CIMT) and ankel brachial index are two independent,simple and non invasive method in vascular complications diagnosis in diabetic patients.The aim of ...
