Key result
Multiple metabolic syndrome components linked to a ~3 bpm greater HRR decline over 7 years.
Why the study?
Does slower heart rate recovery precede the development of metabolic syndrome components in young adults?

Metabolic syndrome components precede greater heart rate recovery decline; leaves open whether slower recovery predicts incident components in young adults.
Cohort (n=4,319)
Does slower heart rate recovery precede the development of metabolic syndrome components in young adults?
Absolute Event Rate: -5.64% vs -2.4%
p-value: p=<0.001
Slower heart rate recovery does not precede the development of metabolic syndrome, but rather appears after metabolic syndrome components are already present.
Kizilbash et al. (2006) conducted a cohort in Metabolic syndrome (n=4,319). Metabolic syndrome components vs. No metabolic syndrome components was evaluated on Longitudinal decline in heart rate recovery (HRR) from baseline to year 7 (p=<0.001). Having two or more metabolic syndrome components at baseline was associated with a significantly larger decline in heart rate recovery over 7 years compared to no components (-5.64 vs -2.40 bpm; P<0.001).
