Risk Factors and Predictive Model Construction for Cerebral Infarction in Patients with Hypertensive Intracerebral Hemorrhage After Minimally Invasive Hematoma Removal Surgery
Objective To explore the risk and risk factors of cerebral infarction in patients with hypertensive intracerebral hemorrhage after minimally invasive hematoma removal surgery,and construct a risk prediction model.Methods Retrospective collect the data of 136 patients with hypertensive cerebral hemorrhage who completed minimally invasive hematoma removal in Xinyang Central Hospital from January 2019 to August 2022.The patient data were consulted and divided into infarct group and non-infarct group according to the occurrence of postoperative cerebral infarction.The clinical data of the two groups were collected and compared.The risk factors of cerebral infarction after minimally invasive hematoma removal in hypertensive intracerebral hemorrhage patients were analyzed by univariate and multivariate analysis.The predictive efficacy was verified by constructing a nomogram model and drawing receiver operating characteristic(ROC)curve.Results Among 136 patients with hypertensive intracerebral hemorrhage,38 cases(27.94％)had secondary cerebral infarction after minimally invasive hematoma removal surgery.After univariate analysis and multivariate logistic regression analysis,the results showed that the course of hypertension,systolic blood pressure,diastolic blood pressure,cerebral hemorrhage volume,and brain tissue displacement were risk factors for cerebral infarction in patients with hypertensive intracerebral hemorrhage after minimally invasive hematoma removal surgery(P＜0.05).A column chart model was drawn to construct a risk prediction model for cerebral infarction after minimally invasive hematoma removal in patients with hypertensive intracerebral hemorrhage.The discrimination of the model showed C-index value was 0.887,with good discrimination.The standard curve showed that the calibration curve was similar to the Y-X straight line,and the accuracy of the model was good.The validation of the model's predictive performance showed that the area under the curve for evaluating the occurrence of cerebral infarction in patients with hypertensive intracerebral hemorrhage after minimally invasive hematoma removal surgery was 0.887,indicating good predictive performance.Conclusion The course of hypertension,systolic blood pressure,diastolic blood pressure,cerebral hemorrhage volume and brain tissue displacement are all risk factors for the occurrence of cerebral infarction in patients with hypertensive intracerebral hemorrhage after minimally invasive hematoma removal surgery.The risk prediction model constructed based on the above risk factors has high predictive value.
