Comparison
Endurance training in addition to cardiac… vs CRT without ET, standard care with ET, and…

Overview
Supports adding endurance training to CRT in chronic HF; extends device-only trials with additive functional gains.
Structured PICO
Does endurance training improve exercise capacity in patients with chronic heart failure and dyssynchrony receiving cardiac resynchronization therapy?
P
Population
36 patients with chronic heart failure and dyssynchrony (17 randomized to CRT +/- ET, 19 matched controls). Randomized cohort: mean age 59+/-9 years, 8 men.
I
Intervention
Endurance training (ET) in addition to cardiac resynchronization therapy (CRT)
C
Comparator
CRT without ET, standard care with ET, and standard care only
O
Outcome
Exercise tolerance (VO2peak, Wattmax, circulatory power) at 5 monthssurrogate
Endurance training added to cardiac resynchronization therapy significantly improves exercise capacity compared to CRT alone in patients with chronic heart failure.
