舒张压水平与急性脑梗死预后的关系

Relationships between diastolic blood pressure and prognosis of acute cerebral infarction

目的 探讨舒张压水平与急性脑梗死患者预后的关系. 方法 回顾性分析200例急性脑梗死患者的临床资料,按入院时舒张压水平将所有患者分为低血压组（舒张压＜70 mm Hg,16例）,正常血压组（舒张压70～90 mm Hg,24例）及高血压组（舒张压＞90 mm Hg,160例）,观察三组患者的预后差别. 结果 低血压组死亡8例（50%）,正常血压组死亡4例（17%）,高血压组死亡60例（38%）,低血压组和高血压组病死率均高于正常血压组（χ^2=3.993、3.046,均P＜0.05）,低血压组与高血压组病死率差异无统计学意义（χ^2=0.959、0.328,均P＞0.05）. 结论 急性脑梗死患者舒张压低于70 mm Hg及高于90 nm Hg者预后不良.

Objective To explore the influence of diastolic blood pressure to prognosis of patients with acute cerebral infarction. Methods Clinical data of 200 patients with acute cerebral infarction were retrospectively reviewed Patients were divided into three groups based on diastolic blood pressure（DBP）when admission;hypotensive group（DBP〈70 mm Hg）,normotensive group（DBP;70-90 mm Hg）and hypertensive group（DBP 〉 90 mm Hg）.Constituent ratio of patients with different level of DBP were calculated and prognosis were compared among the three groups. Results Of all the total patients with acute cerebral infarction,8%（16）presented with hypotension,12%（24）were normotensive and 80%（160）were hypertensive.In the hypotensive group,50%（8）patients died as compared to 17%（4）in normotensive group and 38%（60）in hypertensive group,among all the cases,patients with bypotension or hypertension seemed like to have a higher mortality than normotensive group（P=0.037;χ^2=3.993,P=0.046）,and there was no significant diffenence between two group with hypotension or hypertension. Conclusion The patients with diastolic blood pressure of less than 70 mm Hg or more than 90 mm Hg were predictors of poor outcome.
