Objetive: To evaluate the association between sympathetic nervous system activity and blood pressure variability with central serous chorioretinopathy (CSC). Methods: We performed an individual, observational, and cross-sectional study involving 11 patients with CSC and 16 healthy individuals in similar age range. Participants underwent spectral power analysis of heart rate variability (HRV) at the Hypertension Department of Heart Institute at the University of São Paulo. Results: We demonstrated sympathetic activity predominance in CSC group and found that the LF (low frequency) of heart rate variability was significantly higher in this group (p = 0.04). when compared to control group. The CSC group's mean LF / HF (high frequency) ratio was higher than the control group but was not statistically significant (p = 0.2). Blood pressure variability was higher in CSC patients than in normal patients (p = 0.055), whereas heart rate variability was lower in these patients when compared to normal patients, although no statistical significance was found (p = 0.2). Spontaneous baroreflex function was significantly reduced in patients with CSC when compared to healthy individuals (p = 0.04). Conclusion: Autonomic dysfunction and a predominance of sympathetic modulation were observed in CSC patients. |
