Heart rate variability differences in post-myocardial infarction patients based on initial treatment during acute phase of disease.

ABSTRACT

The aim of study was to asses the heart rate variability (HRV) differences in 128 post-myocardial infarction (MI) patients based on initial treatment during acute phase of disease. The patients were divided into groups group 1 patients who underwent primary PCI, group 2 patients who received fibrinolysis and group 3 patients who were treated conservatively. In comparison with groups 2 and 3, group 1 patients had all HRV analyzed parameters higher except for LF/HF ratio. The results of study suggest that patients who were treated by primary PCI had better preserved autonomic cardiac function compared with patients who received fibrinolysis or those who were treated conservatively in the acute phase of MI.
