The association between blood pressure decreasing rates and survival time in patients with acute intracerebral hemorrhage

There was no established consensus on the optimal blood pressure management protocol in patients with acute intracerebral hemorrhage (ICH). This study was to explore the association between blood pressure decreasing rates and survival time in patients with acute ICH. 786 acute ICH patients were enrolled in the study andhospitalized from2004 to 2006. K-means clustering was used to classify the subjects according to the decreasing rates of blood pressure within 14 days of acute ICH patients. Cox regression was used to screen the independent influencing factors of 14-day survival in the univariate anaylsis among acute ICH patients. There was significant difference in the decreasing rates of systolic blood pressure (SBP) and diastolic blood pressure (DBP) in 1–2 d and 2–3 d after admission in patients with acute ICH (P
