AIM: To evaluate the clinical and prognostic value of the heart rate variability index in patients with congestive heart failure. METHODS: Sixty-four patients with chronic congestive heart failure and sinus rhythm underwent clinical assessment, 24-h ambulatory electrocardiography and echocardiography. Patients were followed for 6 to 30 months. Cardiac death or heart transplantation constituted the primary end-point of the study. RESULTS: The heart rate variability index was related to left ventricular ejection fraction (r=0.29, P=0.02) and New York Heart Association class (P=0.01). Patients with a restrictive left ventricular filling pattern had a lower heart rate variability index compared to patients with a non-restrictive pattern (26+/-11 vs 33+/-9 units, P=0.01). Patients who died (n=11) or underwent heart transplantation (n=4) had a lower heart rate variability index compared to survivors (21+/-10 vs 33+/-9 units, P<0.0001). In multivariate survival analysis, a reduced heart rate variability index was related to survival independent of parameters of left ventricular function. CONCLUSION: The heart rate variability index provides independent information on clinical status and prognosis in patients with chronic congestive heart failure.
