We aimed to profile the current epidemiology of hypertension among the survivors of hemorrhagic stroke in northeast China.
MATERIAL AND METHODS: Our cross-sectional study included 18 796 adults aged 40 years or older and residing in northeast China. Hemorrhagic stroke was identified according to the CT and/or MRI results. Hypertension was defined based on the Chinese hypertension guidelines.
RESULTS: We identified 208 patients with previous hemorrhagic stroke in this population-based study. The overall prevalence of hypertension in the studied population was 88%. Out of all the survivors of hemorrhagic stroke, 80.9% were aware of their hypertensive condition, 70.5% of the patients were in antihypertensive medications treatment, and only 12% of the patients had their blood pressure under control. Furthermore, only 17.10% of the patients who took hypertensive medications achieved appropriate blood pressure. Calcium channel blockers were more commonly used than other medications. Patients with controlled hypertension had significantly higher percentages of comorbidities when compared to those with uncontrolled hypertension. In our patient sample, the rates of stage 2 and stage 3 hypertension in the hemorrhagic stroke population were 28.8% and 15.9%, respectively, and women had a significantly higher prevalence of stage 3 hypertension when compared with men (21.3% vs. 10.0%, P=0.026).
CONCLUSIONS: The high prevalence of uncontrolled hypertension and high rates of blood pressure at stages 2 and 3 in patients with prior hemorrhagic stroke indicated a considerable stroke burden in northeast China. Therefore, effective and long-time management of hypertension in stroke survivors should be a priority.
