BACKGROUND Left ventricular remodeling is a complex pathologic process of progressive left ventricular dilatation, leading to dysfunction and heart failure in patients after myocardial infarction. OBJECTIVE To evaluate biochemical markers, reflecting cardiac remodeling process after first myocardial infarction and compare those markers with clinical(More)
BACKGROUND AND OBJECTIVE Beat-to-beat alteration in ventricles repolarization reflected by alternans of amplitude and/or shape of ECG S-T,T segment (TWA) is known as phenomena related with risk of severe arrhythmias leading to sudden cardiac death. Technical difficulties have caused limited its usage in clinical diagnostics. Possibilities to register and(More)
UNLABELLED Exercise cardiography still remains the cornerstone of noninvasive evaluation of functional status of cardiovascular system and is almost uniformly performed after myocardial infarction. The patients after myocardial infarction can be divided into relative high- and low-risk groups for subsequent cardiac events if all information available on the(More)
The aim of the study was to evaluate changes of ventricular repolarization variables during the exercise test in women with coronary heart disease, to determine variables, which can best predict significant coronary artery stenoses, and to improve noninvasive diagnostics of coronary heart disease. Ninety women with unstable angina pectoris undergone(More)
