Résumé
Hypertension remains the major modifiable risk factor of stroke recurrence. The study aimed to determine the up-to-date epidemiological features of hypertension among the survivors of ischemic stroke. Our cross-sectional study included 18,796 adults aged ≥40 years and residing in northeast China. Ischemic stroke was diagnosed according to the World Health Organization's criteria, which requires the clinical record, computed tomography (CT) and/or magnetic resonance imaging (MRI) during the hospital stay. Hypertension was defined according to the Chinese hypertension guidelines (mean SBP ≥140 mmHg and/or mean DBP ≥90 mmHg, and/or self-reported use of anti-hypertensive medication in the past 2 weeks). Of the 986 survivors of ischemic stroke, 819 (83.1%) were identified with hypertension (535 were pre-stroke hypertension and 284 were post-stroke hypertension). Among hypertensive patients, the awareness and treatment rates were 76.8 and 66.7% respectively. Only 11.0% achieved an appropriate blood pressure (< 140 mmHg and < 90 mmHg) among those who took hypertensive medications. 16.8% of treated hypertensive patients received combination therapy, and calcium channel blockers were the most frequently used anti-hypertensive medication as monotherapy. The mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) of the stroke population was 155.3 ± 22.9 mmHg and 89.2 ± 12.3 mmHg. Both SBP and DBP were higher in rural patients than in urban patients (158.5 ± 23.8 mmHg vs. 146.4 ± 17.5 mmHg and 90.3 ± 12.9 mmHg vs. 85.9 ± 10.1 mmHg, respectively; p < 0.001). The rates of stage 2 and above hypertension in the ischemic stroke population were 32.5 and 18.7%, and was significantly higher in rural areas than in urban areas. The prevalence of poorly-controlled hypertension and the high rates of blood pressures at stages 2 and above in patients with prior ischemic stroke demonstrated an alarming situation in northeast China.

BACKGROUND
Hypertension remains the major modifiable risk factor of stroke recurrence. The study aimed to determine the up-to-date epidemiological features of hypertension among the survivors of ischemic stroke.
METHODS
Our cross-sectional study included 18,796 adults aged ≥40 years and residing in northeast China. Ischemic stroke was diagnosed according to the World Health Organization's criteria, which requires the clinical record, computed tomography (CT) and/or magnetic resonance imaging (MRI) during the hospital stay. Hypertension was defined according to the Chinese hypertension guidelines (mean SBP ≥140 mmHg and/or mean DBP ≥90 mmHg, and/or self-reported use of anti-hypertensive medication in the past 2 weeks).
RESULTS
Of the 986 survivors of ischemic stroke, 819 (83.1%) were identified with hypertension (535 were pre-stroke hypertension and 284 were post-stroke hypertension). Among hypertensive patients, the awareness and treatment rates were 76.8 and 66.7% respectively. Only 11.0% achieved an appropriate blood pressure (< 140 mmHg and < 90 mmHg) among those who took hypertensive medications. 16.8% of treated hypertensive patients received combination therapy, and calcium channel blockers were the most frequently used anti-hypertensive medication as monotherapy. The mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) of the stroke population was 155.3 ± 22.9 mmHg and 89.2 ± 12.3 mmHg. Both SBP and DBP were higher in rural patients than in urban patients (158.5 ± 23.8 mmHg vs. 146.4 ± 17.5 mmHg and 90.3 ± 12.9 mmHg vs. 85.9 ± 10.1 mmHg, respectively; p < 0.001). The rates of stage 2 and above hypertension in the ischemic stroke population were 32.5 and 18.7%, and was significantly higher in rural areas than in urban areas.
CONCLUSIONS
The prevalence of poorly-controlled hypertension and the high rates of blood pressures at stages 2 and above in patients with prior ischemic stroke demonstrated an alarming situation in northeast China.
