Medication Alone may NOT Enough TO HELP ALL Heart Failure Patients
Some heart failure patients could have electrical dyssynchrony (indicators include LBBB1 or QRS ≥ 120 ms2) and may benefit from cardiac resynchronization therapy (CRT).3
For these patients, cardiac resynchronization therapy (CRT), in addition to guideline directed medical therapy (GDMT), is the only therapy clinically proven to help4:
- Improve quality of life5,6
- Slow HF disease progression7
- Decrease mortality8-12
- Reduce HF hospitalizations8-13
WHEN TO REFER VIDEO
CRT Is the only PROVEN way to address electrical dyssynchrony*
The Prevalence of Electrical Dyssynchrony† is Approximately 35% among Patients with More Symptomatic Heart Failure14
CARE-HF4 DEMONSTRATED THAT CRT and Medical therapy work together to improve patient survival

*CRT is the only proven treatment for electrical dyssynchrony supported by randomized clinical trials.3,5
†Patients with a prolonged QRS (>120 ms).
