正常高值血压对急性心肌梗死患者预后的影响

Effects of the high normal blood pressure on the prognosis of patients with acute myocardial infarction

目的探讨正常高值血压对急性心肌梗死患者预后的影响。方法连续选取2009年3月~2014年12月入住我院的急性心肌梗死患者70例,根据血压水平分为正常血压组（n=32）和正常高值血压组（n=38）,观察比较两组患者的临床特点、合并症及主要严重心脑血管事件。结果与正常血压患者比较,正常高值血压发生急性心肌梗死早,恶性心律失常、梗死后心绞痛、再住院率、脑梗死发生率及猝死均高,血清脑钠肽及尿微量白蛋白增高（P〈0.05）。结论正常高值血压患者急性心肌梗死发病早且病情重、并发症多,脑钠肽及尿微量蛋白是可能的预测因素。

Objective To investigate the effects of the high normal blood pressure on the prognosis of patients with a- cute myocardial infarction. Methods A total of 70 patients with acute myocardial infarction in our hospital from March 2009 to December 2014 were divided into normal BP group and high normal BP group according to BP levels; The clinical features, complications and main serious cardiovascular and cerebrovascular cases in two groups were com- pared. Results The acute myocardial infarction occurred earlier, arrhythmia, angina after myocardial infarction, rehospi- talization rate, cerebral infarction and sudden death in high normal BP group were higher than the normal BP group（P〈 0.05）. The brain natriuretic peptide and trace protein in urine also rose in high normal BP group than those in the nor- mal BP group. Conclusion The symptoms in patients of acute myocardial infarction with high normal BP are early and severe and may be with more complications. Brain natriuretic peptide and microalbuminuria are the possible predictors to the prognosis.
