Key result
Cigarette smoking acutely reduced high-frequency heart rate variability by 0.31 ms (p=0.04), and 24-hour HF-HRV was significantly lower in smokers than nonsmokers (5.24 vs 5.63 ms, p=0.01).
Why the study?
Does cigarette smoking reduce high-frequency heart rate variability in healthy individuals with high hostility levels?
Observational (n=149)

Smoking-linked HF-HRV reductions warrant caution in autonomic assessments; leaves open causal links to outcomes and need for prospective trials.
Bodin et al. (2017) conducted an observational in high hostility levels (n=149). Cigarette smoking vs. Nonsmokers and non-smoking moments was evaluated on 24-hour high-frequency heart rate variability (HF-HRV) (p=.01). Cigarette smoking acutely reduced high-frequency heart rate variability by 0.31 ms (p=0.04), and 24-hour HF-HRV was significantly lower in smokers than nonsmokers (5.24 vs 5.63 ms, p=0.01).
