BACKGROUND Previous studies have shown conflicting results about the value of heart rate turbulence (HRT) for risk stratification of patients (pts) with chronic heart failure (CHF). We prospectively evaluated the relation between HRT and progression toward end-stage heart failure or all-cause mortality in patients with CHF. METHODS HRT was assessed from(More)
AIMS To assess the impact of baseline apnoea-hypopnoea index (AHI) on mid-term outcome and its change after 6 months of cardiac resynchronization therapy (CRT) on remote outcome. METHODS AND RESULTS In 71 patients with CRT devices, Holter-derived AHI was assessed before and 6 months after the procedure. Baseline AHI >20 was considered abnormal. After 6(More)
INTRODUCTION The role of heart rate turbulence (HRT) related to baroreflex sensitivity in predicting mortality after myocardial infarction (MI) has been confirmed by several investigators. However, the significance of HRT in predicting major adverse cardiovascular events (MACE) following acute MI is unknown. PURPOSE To analyze the prognostic value of HRT(More)
BACKGROUND Cardiac resynchronization therapy (CRT) improves the clinical status of patients with heart failure (HF), though its effects on heart rate turbulence (HRT) are unknown. METHODS We measured HRT indices in 58 recipients of CRT systems (mean age = 56 +/- 9 years, 41 men) in New York Heart Association HF functional class III-IV, and with a left(More)
BACKGROUND Previous studies showed that the presence of fragmented QRS (f-QRS) in patients with acute coronary syndrome (ACS), who underwent complete revascularisation, is associated with worse prognosis and the possibility of arrhythmia occurrence. AIM To assess the prognostic value of f-QRS in patients with ACS and complete revascularisation, in the(More)
BACKGROUND Prediction of recurrent malignant ventricular tachyarrhythmias after insertion of a implantable cardioverter-defibrillator (ICD) is challenging. Microvolt T-wave alternans (MTWA) seems to be a promising marker of such events in ICD recipients. AIM To assess prognostic significance of MTWA and other noninvasive parameters in the prediction of(More)
BACKGROUND AND AIM The aim of this study was to determine whether gender is related to differences in heart rate turbulence (HRT) parameters and the authors' own predefined HRT categories comprising turbulence timing (TT) in patients at the early stage of acute myocardial infarction (AMI) treated invasively. METHODS We analysed 489 consecutive patients(More)
