Comparison of serum Lp-PLA2 levels in ischemic stroke patients with H-type hypertension or non-H-type hypertension

Background Increased serum Lp-PLA2 levels have been reported in patients who experienced an ischemic stroke; however, the relationship between Lp-PLA2 and H-type hypertension in patients with ischemic stroke remains unclear. Methods In the present study, we investigated the correlation between serum Lp-PLA2 and H-type hypertension in patients with ischemic stroke. A total of 135 patients who experienced acute ischemic stroke were enrolled in Tianjin Huanhu Hospital during October 2015 to May 2016. The demographic characteristics of the patients were collected, and biochemical parameters were detected. Results Among the 135 patients, 111 patients had essential hypertension, including 41 patients with H-type hypertension and 70 with non-H-type hypertension. There were higher proportions of males and patients with diabetes mellitus in the H-type hypertension group compared with the non-H-type hypertension group (P < .05). Lp-PLA2, glucose, and LDL-C levels were higher in the H-type hypertension group than in the non-H-type hypertension group (P < .05). Multivariate logistic regression showed that Lp-PLA2 levels >208.46 mg/L were independently associated with H-type hypertension in patients with ischemic stroke (OR: 2.560, 95% CI: 1.085-6.040, P = .032). The area under the ROC curve of Lp-PAL2 levels in the H-type hypertension group was 0.665 (95% CI: 0.561-0.768, P = .004). Conclusion Synergetic effects of H-type hypertension and Lp-PLA2 levels were noted in the pathogenesis of ischemic stroke.
