Objective To explore the early warning index of ischemic cardiocerebrovascular disease in elderly diabetic patients with plasma LPA. Methods On the basis of public health project,elderly diabetic patients were randomly divided into observation group and control group. Control group adopted diabetes management implementation,while observation group adopted periodic testing of the levels of plasma LPA on the basis of the control group,implementing fall fat,resisting fibrinolytic,antiplatelet aggregation and other interventions if LPA significantly increased. We compared the ischemic cardio-cerebrovascular disease incidence and disease severity between the two groups. Results The incidence of cerebral ischemia in the observation group was higher than that in the control group,and the difference was statistically significant （P<0.05）. Medium and heavy plasma LPA is higher than the light of ischemic cerebrovascular disease group （P < 0.05）,and heavy above medium group （P < 0.05） Conclusion The plasma LPA values can be used as early warning factor in elderly patients with diabetes occuring ischemic cardio-cerebrovascular disease and promote its application.
