Key result
Impaired lung diffusion capacity was independently related to altered parasympathetic response during a respiratory sinus arrhythmia maneuver in COPD patients (r=-0.77, P<0.05).
Why the study?
Is impairment of static lung volumes and lung diffusion capacity related to heart rate variability indices in patients with moderate to severe COPD?

Static hyperinflation may link to reduced vagal HRV in moderate-severe COPD; leaves open clinical relevance and need for prospective trials.

Is impairment of static lung volumes and lung diffusion capacity related to heart rate variability indices in patients with moderate to severe COPD?
Effect estimate: r=-0.77
p-value: p=<0.05
Greater lung function impairment and reduced lung diffusion capacity are associated with poorer heart rate dynamics and altered parasympathetic responses in patients with moderate to severe COPD.
Mazzuco et al. (2015) conducted a cross-sectional in moderate to severe COPD (n=16). Impairment of static lung volumes and lung diffusion capacity was evaluated on Correlation between HRV indices and lung function parameters (r=-0.77, p=<0.05). Impaired lung diffusion capacity was independently related to altered parasympathetic response during a respiratory sinus arrhythmia maneuver in COPD patients (r=-0.77, P<0.05).
