Abstract:
Objective To explore the evaluation value of modified USA National Institutes of Health Stroke Scale (mNIHSS) score combined with bedside transcranial Doppler ultrasonography (TCD) on the early prognosis of ischemic stroke (AIS).Methods One hundred and thirty-six anterior circulation AIS patients were collected,mNIHSS score was evaluated on admission,and emergency bedside TCD examination was performed to evaluate vascular anomalies.After active treatment after discharge,the modified Rankin scale (mRS) score was recorded to evaluate 90 d prognosis.The value of mNIHSS score combined with TCD examination analysis on the prognosis was analyzed.Results If the mNIHSS score ＞ 8 scores was judged to be poor prognosis,the sensitivity was 0.684,the specificity was 0.806,the positive predictive value was 0.578,the negative predictive value was 0.868.If related macro vascular abnormalities in bedside TCD examination were evaluated for clinical prognosis,the sensitivity was 0.736,the specificity was 0.643,the positive predictive value was 0.444,the negative predictive value was 0.863.If both,the specificity was 0.918,the positive predictive value was 0.714,the positive likelihood ratio was 6.41 ;and the two were not available,the negative predictive value was 0.928,negative likelihood ratio was 0.20.Conclusion mNIHSS score combined with TCD examination in evaluating the prognosis of AIS patients can improve the positive or negative predictive value.
