Key result
Psychological mood states were associated with impedance-derived hemodynamics, including a negative correlation between tension-anxiety and log stroke volume.
Why the study?

Are psychological mood states associated with resting hemodynamic variables measured by impedance cardiography?
Psychological mood states, specifically tension-anxiety and fatigue-inertia, are associated with underlying hemodynamic variables such as stroke volume and cardiac output, despite no significant association with basic blood pressure or heart rate.

Mood states linked to impedance hemodynamics but not BP/HR; leaves open causal psychocardiac mechanisms in cross-sectional data.
OBJECTIVE: This exploratory study investigated the relation between psychological mood states and hemodynamic variables obtained at rest. METHODS: We measured resting hemodynamic variables using impedance cardiography, blood pressure, heart rate, and the Profile of Mood States (POMS) in 71 participants. RESULTS: Mood states were not significantly associated with heart rate, systolic, diastolic, or mean arterial pressure. In comparison with these basic measures of physiology, a number of impedance derived measures of hemodynamics were associated with mood states. Log stroke volume was negatively correlated with POMS tension-anxiety (r = -.319, p = .009) and fatigue-inertia (r = -. 316, p = .009). Log cardiac output was negatively associated with fatigue-inertia (r = -.346, p < .01). Log total peripheral vascular resistance was positively correlated with POMS fatigue-inertia (r = .276, p = .024). CONCLUSIONS: Our findings suggest that mood states are associated with hemodynamic variables underlying blood pressure.

Bum-Hee et al. (2001) reported a cross-sectional. Psychological mood states was evaluated on Relation between psychological mood states and hemodynamic variables (r = -0.319, p=0.009). Psychological mood states were associated with impedance-derived hemodynamics, including a negative correlation between tension-anxiety and log stroke volume.
