In this study, we investigated the myocardial inflammation and mitochondrial function during venovenous extracorporeal membrane oxygenation (VV ECMO) and further evaluated the effects of continuous renal replacement therapy (CRRT) on them. Eighteen piglets were assigned to the control group, ECMO group, and ECMO+CRRT group. Myocardial inflammation was assessed by the activity of myeloperoxidase (MPO), myocardial concentrations, and mRNA expression of TNF-α, IL-1β, and IL-6; mitochondrial function was assessed by activities of mitochondrial complexes I-V. VV ECMO elicited a general activation of serum and myocardial inflammation and significantly decreased the activities of mitochondrial complexes I and IV. After being combined with CRRT, serum and myocardial concentrations of IL-1β and IL-6, myocardial mRNA expression of IL-6, and the activity of MPO were decreased significantly; the activities of mitochondrial complexes were increased. We conclude that myocardial inflammation was activated during ECMO therapy, inducing mitochondrial injury; moreover, CRRT reduced myocardial inflammation and partially ameliorated mitochondrial function.

Psychological Health, Well-Being, and the Mind-Heart-Body Connection: A Scientific Statement From the American Heart Association

Based on current study data, the following statements can be made: There are good data showing clear associations between psychological health and CVD and risk; there is increasing evidence that psychological health may be causally linked to biological processes and behaviors that contribute to and cause CVD; the preponderance of data suggest that interventions to improve psychological health can have a beneficial impact on cardiovascular health; simple screening measures can be used by health care providers for patients with or at risk for CVD to assess psychological health status; and consideration of psychological health is advisable in the evaluation and management of patients with or at risk for CVD.
