Key result
The presence of two or more depressive symptoms was significantly associated with reduced heart rate variability in women aged 30-65 years 3-6 months after an acute coronary event.

Are depressive symptoms associated with reduced heart rate variability in younger women after an acute coronary event?
In younger women recovering from an acute coronary event, the presence of depressive symptoms is associated with reduced heart rate variability, suggesting a potential autonomic mechanism for increased arrhythmia susceptibility.
Zimmermann‐Viehoff et al. (2010) conducted a cohort in Acute coronary event (myocardial infarction or unstable angina pectoris) (n=292). High depressive symptoms (≥2 symptoms) vs. Low depressive symptoms (0-1 symptom) was evaluated on Heart rate variability (HRV) indices. The presence of two or more depressive symptoms was significantly associated with reduced heart rate variability in women aged 30-65 years 3-6 months after an acute coronary event.
