Key result
Acute schizophrenia in unmedicated patients was associated with reduced mean RR interval and heart rate variability levels compared with healthy volunteers, indicating autonomic dysregulation.
Why the study?
Is acute schizophrenia associated with cardiac autonomic dysfunction compared to healthy volunteers?
Case-Control (n=723)
Is acute schizophrenia associated with cardiac autonomic dysfunction compared to healthy volunteers?
Acute schizophrenia is associated with cardiac autonomic dysregulation, characterized by reduced heart rate variability, which correlates with the severity of positive symptoms.
No takes yet. Share an insight, caveat, or question.
May warrant cardiac monitoring in acute schizophrenia; leaves open whether reduced HRV predicts outcomes or responds to treatment.
Chang et al. (2012) conducted a case-control in Acute schizophrenia (n=723). Acute schizophrenia vs. Healthy volunteers was evaluated on Cardiac autonomic function (heart rate variability parameters). Acute schizophrenia in unmedicated patients was associated with reduced mean RR interval and heart rate variability levels compared with healthy volunteers, indicating autonomic dysregulation.
