Post-stroke hypertension is associated with poor short-term outcome, although the results have been conflicting. Our objective was to evaluate the association of blood pressure (BP) and in-hospital outcomes in patients with acute ischaemic stroke.
Patients in the Get With The Guidelines-Stroke registry with acute ischaemic stroke were included. Admission systolic and diastolic BP was used to compute mean arterial pressure (MAP) and pulse pressure (PP). The outcomes of interest were: in-hospital mortality, not discharged home, inability to ambulate independently at discharge and haemorrhagic complications due to thrombolytic therapy. A total of 309 611 patients with an ischaemic stroke were included. There was a J-shaped/U-shaped relationship between systolic BP and outcomes. Both lower and higher systolic BP values, compared with a central reference value, had higher risk of in-hospital death [e.g. adjusted odds ratio (95% confidence interval) (OR[CI]) = 1.16[1.13-1.20] for 120 vs. 150 mmHg and 1.24[1.19-1.30] for 200 vs. 150 mmHg], not discharged home (OR[CI] = 1.11[1.09-1.13] for 120 vs. 150 mmHg and 1.15[1.12-1.18] for 200 vs. 150 mmHg), inability to ambulate independently at discharge (OR[CI] = 1.16[1.13-1.18] for 120 vs. 150 mmHg and 1.09[1.06-1.11] for 200 vs. 150 mmHg). However, risk of haemorrhagic complications of thrombolytic therapy was lower with lower systolic BP (OR[CI] = 0.89[0.83-0.97] for 120 vs. 150 mmHg), while higher with higher systolic BP (OR[CI] = 1.21[1.11-1.32] for 200 vs. 150 mmHg). The results were largely similar for admission diastolic BP, MAP, and PP.
In patients hospitalized with ischaemic stroke, J-shaped, or U-shaped relationships were observed between BP variables and short-term outcomes. However, haemorrhagic complications with thrombolytic therapy were lower with lower BP.
卒中后高血压与短期预后不良相关，但结果存在争议。我们的目的是评估急性缺血性卒中患者的血压（BP）与院内结局的关系。
纳入 Get With The Guidelines-Stroke 登记处的急性缺血性卒中患者。入院时的收缩压和舒张压用于计算平均动脉压（MAP）和脉压（PP）。主要结局为院内死亡率、未出院回家、出院时不能独立行走和溶栓治疗所致出血性并发症。共纳入 309611 例缺血性卒中患者。收缩压与结局之间存在 J 形/倒 U 形关系。与中心参考值相比，较低和较高的收缩压值均增加院内死亡风险[例如，120 与 150mmHg 相比，调整后的比值比（95%置信区间）（OR[CI]）为 1.16[1.13-1.20]，200 与 150mmHg 相比，OR[CI]为 1.24[1.19-1.30]]，未出院回家（OR[CI]为 1.11[1.09-1.13]，120 与 150mmHg 相比，OR[CI]为 1.15[1.12-1.18]，200 与 150mmHg 相比），出院时不能独立行走（OR[CI]为 1.16[1.13-1.18]，120 与 150mmHg 相比，OR[CI]为 1.09[1.06-1.11]，200 与 150mmHg 相比）。然而，较低的收缩压与溶栓治疗的出血性并发症风险较低相关（OR[CI]为 0.89[0.83-0.97]，120 与 150mmHg 相比），而较高的收缩压与溶栓治疗的出血性并发症风险较高相关（OR[CI]为 1.21[1.11-1.32]，200 与 150mmHg 相比）。入院舒张压、MAP 和 PP 的结果基本相似。
在因缺血性卒中住院的患者中，BP 变量与短期结局之间观察到 J 形或倒 U 形关系。然而，较低的 BP 与溶栓治疗的出血性并发症较低相关。
