Risk stratification in advanced heart failure using lorenz plot indices of heart rate variability

The availability of powerful but expensive therapeutic means necessitates optimization of risk strat$cation ofpatients with advanced heart failure for both medical and economic reasons. Tradirional methods of heart rate van´- ability have been suffering f i m low predictive accuracy regarding identi$cation of patients who are at high risk of cardiac death, We showed that Lorenz plot based heart rate variability indices are useful in signtjkantly improving risk stratijication in patients suffering from advanced hem failure.
