Role of dyslipidemia in ischemic stroke patients treated in the telestroke network.

PURPOSE

The relationship between the telestroke technology and clinical risk factors in a dysplipidemic ischemic stroke population and neurologic outcomes is not fully understood. This issue was investigated in this study.

PATIENTS AND METHODS

We analyzed retrospective data collected from a regional stroke registry to identify demographic and clinical risk factors in patients with improving (NIHSS ​≤ ​7) or worsening (NIHSS ​> ​7) neurologic outcome in dyslipidemic ischemic stroke population. We used logistic multivariate models to identify independent predictors of improving or worsening outcome based on dyslipidemia disease status in ischemic stroke patients.

RESULTS

In the adjusted analysis for dyslipidemic ischemic stroke population, cholesterol reducer use (odd ratio; [OR] ​= ​0.393, 95% confidence interval [CI], 0.176-0.879, P ​= ​0.023) and direct admission (OR ​= ​0.435, 95% CI, 0.199-0.953, P ​= ​0.037) were more likely to be associated with neurologic improvement and no clinical or demographic factors were associated with poor neurologic outcome in dyslipidemic ischemic stroke patients treated in the telestroke network. For the ischemic stroke population without dyslipidemia, increasing age (OR ​= ​1.070, 95% CI, 1.031-1.109, P ​< ​0.001), coronary artery disease (OR ​= ​3.633, 95% CI, 1.307-10.099, P ​= ​0.013), history of drug or alcohol abuse (OR ​= ​6.548, 95% CI, 1.106-38.777, P ​= ​0.038), and improvement in ambulatory outcome (OR ​= ​2.880, 95% CI, 1.183-7.010, P ​= ​0.020) were associated with worsening neurological functions, while being Caucasian (OR ​= ​0.294, 95% CI, 0.098-0.882, P ​= ​0.029) was associated with improving neurologic functions.

CONCLUSION

Demographic and clinical risk factors among the dysplipidemic ischemic stroke population in the telestroke network were not associated with worsening neurologic functions.
