Sažetak
Background: Auditory stimulation increases mean blood flow velocity (MBFV) in the middle cerebral artery (MCA) in healthy individuals. Our aim was to monitor such changes in the affected MCA of patients with acute ischemic stroke (AIS) and to compare them with healthy individuals. Methods: The study included 113 examinees (52 non thrombolysed patients admitted to he hospital within 24 hours of onset, and 61 healthy individuals). In stroke patients (group2) only the affected MCA was insonated by means of TCD while in healthy individuals (group1) both MCAs were recorded. MCA MBFV were monitored during listening to relaxing music for two minutes. Prior to this, a baseline MBFV value was recorded for each person. The first response of MBFV increase was measured at the time (Tmax) and percentage of change in amplitude was considered significant. Pearson Chi-Square test was used for statistical analysis. Results: In both groups there was an increase in MBFV compared to baseline values as a reaction to the music. In group1 91.8% of individuals had a significant increase in Amax while in group2 such an increase was recorded in 78.85% of patients. Tmax in group2 (15.87 +- 7.72) was significantly longer (p<0.01) than Tmax in group1 (9.34 +- 6.16). There was no statistically significant difference in Amax between the two groups. Conclusion: We have determined that music is an auditory stimulus in stroke patients which was measured by means of TCD as MCA MBFV increase. However, compared to healthy subjects, affected MCAs in stroke patients needed more time to react.
