Risk prediction by heart rate turbulence and deceleration capacity in postinfarction patients with preserved left ventricular function retrospective analysis of 4 …
BACKGROUND AND AIM: In the Improved Stratification of Autonomic Regulation–Risk trial,
postinfarction patients with severe autonomic failure (SAF)—defined as abnormal heart rate
turbulence in the presence of abnormal deceleration capacity (DC)—were at high risk of
subsequent death, even if left ventricular function was not particularly compromised. The aim
of this study was to investigate SAF as a risk predictor in independent postinfarction cohorts.
METHODS AND RESULTS: The data of 3 postinfarction trials (ie, St George's Hospital …
