[Value of exercise electrocardiography and other current instrumental studies in the evaluation of percutaneous coronary interventions and in the detection of restenosis].
The current instrumental studies (graded exercise echocardiography (ECG)), exercise tests in combination with myocardial imaging (echocardiography, myocardial perfusion scintigraphy) used to evaluate restenosis after percutaneous coronary interventions (PCI) in patients with coronary heart disease are considered. The sensitivity, specificity, and prognostic value of these studies versus coronarography in the diagnosis of restenosis after PCI are given. The capabilities of other diagnostic techniques (ultrasound study of brachial artery dysfunction, intravascular ultrasound study of coronary arteries, multispiral computed tomography, etc.) are analyzed. It is emphasized that periodic use of exercise ECG tests after PCI has no advantages over their performance only on the basis of the clinical findings of the impact on quality of life, functional status, and clinical signs.
