				        	Objective:To investigate the blood pressure variability and its clinical significance in patients with acute cerebral infarction who combined with H type hypertension.Methods: 95 patients with acute cerebral infarction who combined with H type hypertension were enrolled in the perspective study. According to the homocysteine(Hcy) level of patients, they were divided into observation group ( Hcy ≥10mmol/L, 51cases) and control group (Hcy<10mmol/L, 44cases). The blood pressure variability and main clinical features of these patients in the two groups in 24h were observed. At the same time, the correlation between blood pressure variability and main clinical feature in observation group were analyzed.Results: The 24h systolic pressure variability, 24h diastolic pressure variability, carotid intima-media thickness and national institute of health stroke scale (NIHSS) of observation group were 14.57±4.62, 18.57±5.38, 13.39±4.85 mm and 1.27±0.17, respectively. While they were 12.48±3.78, 16.12±5.74, 11.34±4.32 mm and 1.09±0.13 in the control group, respectively. And the differences of them between the two groups were statistical significance (t=2.389,t=2.146,t=2.160,t=5.725,P<0.05). Besides, there was obvious positive correlation between 24h systolic pressure variability and NIHSS of patients with acute cerebral infarction (r=0.254,P<0.05), and there was also obvious positive correlation between 24h systolic pressure variability and thickness of carotid intima-media (r=0.256,P<0.05).Conclusion: Increased blood pressure variability in patients with acute hypertensive cerebral infarction combined with H type hypertension may be related to poor prognosis of patients and vascular intima thickness.
