Abstract:
Relationship between parameters describing clinical status of the patient in acute phase of myocardial infarction, outcome results and quantitative estimates of T-wave alternans, known prognostic factor of severe cardiac arrhythmias or sudden cardiac death, was investigated in aim to reveal their usefulness and incremental diagnostic utility. Integrated estimate, reflecting differences between S-T,T complexes of odd and even cardiocycles, obtained by means of Principal Component Analysis showed significant correlation with Left Ventricular Ejection Fraction and rehospitalization of patient within 6 months.
