[目的]了解24h血压监测在心肌梗死患者病情评估中的临床应用价值。[方法]选择2009年1月～2010年12月某院收住的48例心肌梗死患者。对照分析心肌梗死患者不同时期24h动态血压及不同程度心肌梗死者血压昼夜节律情况。[结果]心肌梗死患者不同时期24h动态血压对照显示,差异性显著。不同程度心肌梗死者血压昼夜节律情况对照显示,血压昼夜节律正常者和减弱者构成比无差异性;消失者构成比差异性显著。[结论]心肌梗死时患者会出现血压昼夜节律减弱或消失,且其减弱或消失的变化与心肌梗死程度有一定的相关性,可利用24h血压监测来辅助诊断心肌梗死情况。
[Objective] To understand the clinical value of 24h blood pressure monitoring in the assessment of myocardial infarction patients. [Method] Select 48 patients with myocardial infarction admitted in a hospital from January 2009 to December 2010. Control analysis of 24h ambulatory blood pressure at different periods of patients with myocardial infarction and different degree of myocardial infarction blood pressure circadian rhythm. [Result] The ambulatory blood pressure control at different periods of myocardial infarction patients showed significant difference. Comparison of circadian rhythm of blood pressure in patients with different degrees of myocardial infarction showed that there was no difference in the composition ratio of normal and impaired blood pressure circadian rhythm; [Conclusion] The circadian rhythm of blood pressure may be weakened or disappeared in patients with myocardial infarction, and the change of diminished or disappeared is correlated with the degree of myocardial infarction. 24h blood pressure monitoring can be used to assist in the diagnosis of myocardial infarction.
