Relationship between hypertension and pulsatility index in acute ischemic stroke patients

Abstract

Hypertension is one of the risk factors for stroke. In the United States, stroke is the third leading cause of death, with a death rate of 146,664 people. Pulsatility index (PI) examination on transcranial Doppler is a value generated by blood flow velocity and blood viscosity. Methods: Retrospective analytic observational study with a cross-sectional study design in patients with acute thrombotic stroke with hypertension according to JNC VIII criteria. Data were obtained from secondary data from medical records of patients treated in the nervous room of Dr RSUD. Soetomo, in the period from February 2019 to February 2022, met the inclusion criteria, namely being over 18 years old, undergoing a TCD examination and having a stroke for the first time. Statistical analysis using Spearman correlation test with a significance value <0.05. Results: A total of 46 subjects met the inclusion and exclusion criteria. Tension with a mean of 152.00 ± 20.87 and a mean value of PI 1.08 ± 0.73. The Spearman statistical test showed a positive correlation with a substantial and statistically significant relationship level (rho = 0.712, p=0.002). Conclusion: there is a strong significant relationship between hypertension and the pulsatility index in patients with acute thrombotic stroke
