Key result
Physiological pacing and cardiac rehabilitation linked to ~71% lower MECKI score and reduced mortality risk.
Why the study?
Heart failure studies have relied on a single baseline MECKI score, leaving unclear whether treatment optimization with physiological pacing or cardiac rehabilitation improves the score and its prognostic impact.
Does optimization of treatment with physiological pacing or cardiac rehabilitation improve the MECKI score in patients with HFrEF?
Population
107 patients with HF with reduced LVEF on optimal medical treatment able to exercise
Comparison
Physiological pacing pacemaker implantation or cardiac rehabilitation program inclusion
Design
Retrospective study
Follow-up
6-month follow-up

MECKI responsiveness to optimization may refine HFrEF risk assessment; extends observational data but leaves causal effects open.
Does optimization of treatment with physiological pacing or cardiac rehabilitation improve the MECKI score in patients with HFrEF?
Optimization of HFrEF treatment through physiological pacing or cardiac rehabilitation significantly improves the MECKI score, highlighting its dynamic prognostic value.
Irache et al. (2025) studied this question. Physiological pacing and cardiac rehabilitation improved MECKI score from 5.9 to 1.7 (p<0.001) over 6 months, reducing 2-year mortality or HF transplant risk.
