TL;DR
Besides low left ventricular ejection fraction, HR variability parameters reflecting impaired vagal tone (SDNN, pNN50) were found to predict an increased risk of cardiac death and death due to progressive pump failure.
Abstract
To study the prognostic value of heart rate (HR) variability in heart failure, risk assessment of clinical and HR variability parameters was performed in 159 patients with stable chronic heart failure. Besides low left ventricular ejection fraction, HR variability parameters reflecting impaired vagal tone (SDNN, pNN50) were found to predict an increased risk of cardiac death and death due to progressive pump failure.

Measurements of Hemodynamics, plasma norepinephrine, and plasma renin activity in patients with moderate to severe congestive heart failure suggest that a single resting venous blood sample showing the plasma norenphrine concentration provides a better guide to prognosis than other commonly measured indexes of cardiac performance.

The two most important techniques used to study the autonomic nervous system--heart rate variability and baroreflex sensitivity--are reviewed, and the clinical and experimental data suggesting that these techniques are powerful predictors of future arrhythmic events are discussed in depth.

Correlations between the time and frequency domain measures of heart period variability and previously identified postinfarction risk predictors, e.g., left ventricular ejection fraction and ventricular arrhythmias, are remarkably weak.

A generally stronger and negative relation was demonstrated between spectral and nonspectral measurements of HR variability, and indicators of sympathoexcitation, muscle sympathetic nerve activity and plasma norepinephrine.

Results demonstrate that long-term treatment of patients having congestive heart failure with an angiotensin-converting enzyme inhibitor is associated with a restoration of autonomic balance, which derives in part from a sustained augmentation of parasympathetic tone.

The present data show that HR variability has a statistically significant, but moderate, correlation with clinical variables of severity of CHF, and therefore, HR variability analysis may be a new, important tool in the clinical assessment ofCHF patients.
