[Abstract] Objective To investigate the relationship between anxiety and blood pressure and heart rate variability in patients with acute hypertension. Methods In this study, 84 patients with acute hypertension from January 2020 to April 2022 were observed. Anxiety was evaluated on admission using the Self-Assessment Scale for Anxiety (SAS) and was set up as anxiety group as well as non-anxiety group, 38 cases versus 46 cases. The 24-h mean systolic and diastolic blood pressure (24-h SBP), (24-h DBP), SBP, DBP fluctuation range (ΔSBP), and (ΔDBP) were compared between the two groups. Heart rate variability was detected, including root mean square of the difference between adjacent NN intervals (RMSSD), standard deviation of NN intervals (SDNN), and standard deviation of the mean of NN intervals (SDANN). The correlation between SAS score and blood pressure and heart rate variability was also analyzed. Results 24h SBP, 24h DBP, ΔSBP, and ΔDBP were significantly higher in the anxiety group than in the control group (P<0.05). RMSSD, SDNN, and SDANN were significantly lower in the anxiety group than in the control group (P<0.05). SAS scores were positively correlated with 24h SBP, 24h DBP, ΔSBP, and ΔDB, and negatively correlated with RMSSD, SDNN, and SDANN (P<0.05). Conclusion Anxiety is more common in patients with acute hypertension, and it increases the magnitude of blood pressure elevation and decreases heart rate variability.
