title: Characteristics of pulse pressure parameters in acute intracerebral hemorrhage patients.
abstract: We explored the features of changes in pulse pressure (PP) in patients with intracerebral hemorrhage (ICH). Two hundred one patients with ICH were admitted to our hospital from January 2008 to August 2009. Meanwhile, another 201 people matching in age and gender with these patients were assigned as controls. Blood Pressures (BP) were collected within the first 24 h after admission. PP was calculated from the BP readings. The mean of PPs was compared via T-test. The distributed frequency of the PP level was analyzed using the chi-square test. PPs in the ICH group were higher than those of the controls (P<0.001). Chi-square test showed a significant difference in distribution ratios of PP (P<0.01) between the ICH and control group. The largest PP range in the ICH group was from 80 to 99 mmHg, which accounted for 33.3%; PP of the control group was from 40 to 49 mmHg (30.3%). The PP level in the 40-89-year-old case group was higher than that in the 40-89-year-old control group. PP increased with age. Our investigation indicates that higher PP is correlated with acute ICH and that PP is important in predicting the risk of ICH.
