Abstract:

Objective To study the roles of serum interleukin-6(IL-6) and D-dimer(DD) levels in predicting the risk of cerebral hemorrhage in patients with hypertension. Methods A total of 400 hypertensive patients were enrolled and followed up for 5 years. The serum IL-6 and DD levels were determined and compared between cerebral hemorrhage occurring group and non-occurring group. Logistic regression analysis was used to evaluate the risk factors for cerebral hemorrhage in patients with hypertension. Receiver operating characteristic(ROC) curve was used to evaluate the predictive roles of serum IL-6 and DD levels for cerebral hemorrhage. Results After 5 years of follow-up,62 cases of 400 hypertensive patients were lost to follow-up,and 32(9.47%) cases of cerebral hemorrhage occurred in the remaining 338 cases. The carotid atherosclerosis ratio,cerebral microhemorrhage ratio,serum IL-6 level,serum DD level and the course of hypertension were 87.50%,25.00%,(19.02±2.51) pg/mL,(318.40±57.85) μg/L and(12.54±2.34) years,respectively. Compared with non-occurring group,the carotid atherosclerosis and cerebral microhemorrhage ratios,serum IL-6 and DD levels and the course of hypertension were higher(χ2=15.317,P<0.001;χ2=5.872,P=0.015;t=7.915,P<0.001;t=24.694,P<0.001;t=14.753,P<0.001). The carotid atherosclerosis,cerebral microhemorrhage,the course of hypertension,IL-6 and DD were risk factors of cerebral hemorrhage in hypertensive patients(P<0.05). The optimal cut-off values of serum IL-6 and DD levels to predict cerebral hemorrhage in hypertensive patients were 18.35 pg/mL and 287.51 μg/L,respectively,and the areas under curves of single and combined determinations were 0.706,0.731 and 0.795,respectively. Conclusions The combined determination of serum IL-6 and DD plays a role in predicting the risk of cerebral hemorrhage in patients with hypertension,which can provide a reference for the prevention of cerebral hemorrhage.
