Abstract:
Objective To study the effect of abnormal blood pressure (BP) circadian rhythm on subtypes of acute ischemic stroke (AIS) in hypertensive patients .Methods Ninety-seven AIS pa-tients with hypertension were divided into arterothrombosis (AT)group (n=66)and small artery disease (SAD)group (n=31)according to the modified TOAST classification .Their 24 h ambula-tory BP was monitored .The 24 h BP ,daytime and nighttime BP ,morning BP surge and BP circa-dian rhythm were compared between the two groups .Results The nighttime SBP was significant-ly higher in AT group than in SAD group (133 .86 ± 18 .17 mm Hg vs 124 .42 ± 16 .06 mm Hg , P<0 .05) .The absent rate of BP circadian rhythm was higher in AT group than in SAD group (84 .8% vs 64 .5% ,P<0 .05) .However ,no significant difference was found in morning BP surge between the two groups (37 .9% vs 19 .4% ,P>0 .05) .Conclusion Absent BP circadian rhythm and elevated nighttime BP are related with AT type ischemic stroke .
