The structure of comorbidity in patients with coronary artery disease and stenting of coronary arteries after myocardial infarction

In recent years, it has become possible to obtain a holistic view of the mechanics of contraction and relaxation of various zones of the myocardium using methods for assessing myocardial deformation. Echocardiographic (EchoCG) examination of patients with coronary heart disease (CHD) is an important diagnostic method that allows monitoring the patient before and after revascularization. IHD can manifest itself in the form of angina attacks, differing in duration and severity. It should be noted that in case of exertional angina during standard echocardiography, changes in the contractile function of the left ventricle (LV) may not be observed, while in unstable angina, it is possible to identify zones of hypo- or a kinesis.
