Myocardial perfusion imaging and cardiac events in asymptomatic patients with diabetes
نویسنده
چکیده
Myocardial perfusion single-photon emission computed tomography (MP-SPECT) has become essential for screening diabetic patients at high risk of silent myocardial ischemia. The combined use of pharmacological and exercise stress, together with the generalization of gated studies has increased both the sensitivity and the specificity of MP-SPECT, leading to a better identification of balanced coronary artery disease, of coronary artery disease with normal coronary angiography, and artifacts. In addition, the incremental prognostic value of gated MP-SPECT over myocardial perfusion and clinical data has been demonstrated. However, the selection of those asymptomatic diabetic patients who will benefit from screening remains an open question. A more refined estimation of cardiovascular risk factors is required.

Introduction: One of the most important causes of death in patients with end-stage renal disease (ESRD) and even after kidney transplantation is cardiovascular diseases. Thus, cardiac evaluation is of utmost importance in the management of these patients especially during preoperative work up before renal transplantation. The aim of present study is to evaluate the role of myoc...

Objective: Although coronary artery disease (CAD) is the leading cause of death in type 2 diabetic patients, it is frequently asymptomatic. Myocardial perfusion imaging (MPI) is reported to show ischemia in a significant number of asymptomatic diabetic patients. We studied the prevalence and severity of myocardial perfusion defects in asymptomatic diabetic patients and its clinical impact. Meth...

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 ...
