[The Diagnostic Accuracy of Exercise Treadmill Testing and Stress Echocardiography for the Detection of Obstructive Coronary Artery Disease in Patients Aged ≥ 70 Years].

Aim: to compare diagnostic accuracy of exercise treadmill testing and stress echocardiography in the diagnosis of stable coronary artery disease (CAD) in patients aged >70 years.

Materials And Methods: The study included 390 patients aged >70 years with suspected stable ischemic heart disease, who underwent elective coronary artery angiography (CAG). Exercise treadmill testing (ETT) according to the modified Bruce protocol was carried out in 189 patients (48 %), bicycle stress echocardiography - in 179 patients (46 %).

Ig apheresis for the treatment of severe DCM patients.

Background: Autoantibodies against β1-adrenoreceptor (AR) are considered by many authors to be the most significant in autoimmune process during DCM. Immunoadsorption (IA) of immunoglobulins (Ig apheresis) is a logic approach to remove autoantibodies against β1-AR and other antibodies. The effect of Ig apheresis and the role of anti-β1-AR in DCM are still an issue for discussion.
