Key result
Low heart-rate variability (<70 ms) and baroreflex sensitivity (<3.0 ms/mmHg) independently predicted post-infarction cardiac mortality, increasing 2-year mortality to 17% when both were low.
Why the study?
Do low heart-rate variability and baroreflex sensitivity predict cardiac mortality in patients with recent myocardial infarction?
Do low heart-rate variability and baroreflex sensitivity predict cardiac mortality in patients with recent myocardial infarction?
Low heart-rate variability and baroreflex sensitivity are independent predictors of cardiac mortality after recent myocardial infarction, adding prognostic value beyond LVEF and ventricular arrhythmias.

May refine post-MI risk stratification beyond LVEF; leaves open prospective validation before clinical use.
Rovere et al. (1998) studied this question. Low heart-rate variability (<70 ms) and baroreflex sensitivity (<3.0 ms/mmHg) independently predicted post-infarction cardiac mortality, increasing 2-year mortality to 17% when both were low.
