Heart failure & cardiomyopathies

Association of left ventricular remodeling with cardiac resynchronization therapy outcomes

Heart RhythmPublished Secondary analysis of the REVERSE randomised trial

Authors' conclusion

Preventing further increase in LVESV with CRT was associated with reduced mortality, whereas functional measure improvement was associated with LV remodeling magnitude.

Study context

Population
Subjects randomised to CRT-ON in the REVERSE trial (systolic left ventricular (LV) dysfunction)CRT-ON arm
Participants
353 subjects
Comparison
Cardiac resynchronization therapy (CRT) outcomes by extent of LV remodeling
Primary endpoint
Long-term CRT outcomes (all-cause mortality, health status, quality of life, 6-minute hall walk) by extent of LV remodeling
Follow-up
Annually for 5 years
Methodological detailsprospective, double-blind, Subjects evaluated annually for 5 years
  • Prospective
  • Double-blind
  • Subjects evaluated annually for 5 years

Primary result

As reported in the abstract

All-cause mortality

P < 0.0001

No difference in survival among stabilized, responder and super-responder groups
P = 0.87

Further findings

Health status and quality of life

Significant interaction between LV end-systolic volume (LVESV) group and time
P = 0.02
  • P = .02 for both

6-minute hall walk

Interaction between LVESV group and time not significant
P = 0.79
Super-responders had increased walk distance vs other 3 response groups
P = 0.03
