Simplified peak power reserve in patients with an implantable cardioverter-defibrillator and advanced heart failure.
The prognostic ability of simplified peak power (SPP) reserve, a novel measure of left ventricular systolic performance, was prospectively studied in patients with advanced heart failure (HF) and implantable cardioverter-defibrillators. Reduced SPP reserve identified patients who are at high risk for experiencing progressive HF.
