Objective? To explore the reasons of hypertensive patients' uncontrolled blood pressure before onset of ischemic stroke so as to provide clinical evidence for stroke prevention. Methods? The phenomenological analysis method in qualitative research was applied. From February to June 2016, 15 hypertensive ischemic stroke patients with hypertensive cerebral infarction and low medication adherence admitted to the department of neurology of three tertiary hospitals in Guangdong province were selected and participated in qualitative interviews. Results? By Colaizzi phenomenological analysis method, the medication misconception of patients were summarized into 4 themes: estimating physical condition by self-feeling, holding the opinion that there was few relation between "whether monitoring blood pressure", "forgetting medication","stopping medication because of various reasons" and cerebral infarction. Conclusions? There are some misunderstandings in the cognition of taking medicine before the onset of hypertensive cerebral infarction. It suggests that we should strengthen blood pressure monitoring and health education of drug compliance in hypertensive patients and hypertensive cerebral infarction patients, so as to improve the effect of primary prevention and secondary prevention of stroke.

Objective To explore the prevalence of diabetes and hyperlipidemia in cerebral infraction patients with hypertension and look into the rates of awareness, treatment and control. Methods Blood pressure, blood glucose and blood lipids were measured in 238 cerebral infraction patients with hypertension. Meanwhile, the rate of awareness, treatment and control of hypertension, diabetes and hyperlipidemia were investigated by questionnaire. Results Among 79.41％of the patients had abnormal blood pressure and cerebral infaction on admission, the rates of awareness , treatment and control of hypertension were 74.79％, 67.23％, 20.59％. 10.11％of them never took antihypertensive drugs in spite of their awareness of hypertension. 32.35％ of the patients were combined with diabetes, the rates of awareness, treatment and control were 79.22％, 62.34％, 12.99％respectively, and among them 21.31％never tookantidiabetic drugs in spite of awareness of diabetes. 81.51％ of the patients were combined with hyperlipidemia, the rates of awareness, treatment and control were 23.20％, 6.70％, 1.55％respectively, and among them 71.11％never took lipid-lowering drugs with awareness of high blood lipid. Conclusions 79.41％ of the incidence of cerebral infraction was related to abnormal blood pressure. 32.35％cerebral infarction patients with hyperlipdemioa are complicated with hypertension diabetes;81.51％are complicated with 28.57％cerebral infraction patients with hypertension were complicated with diabetes and hyperlipidemia as well, but the rate of awareness, treatment and control were relatively low. In order to improve the secondary prevention, we should pay more attention to the stroke risk factors, and help make the individualized medicine-taking plan to improve the control rate.
