急性心肌梗死患者动态血压变化

The changes of ambulatory blood pressure in acute myocardial infarction

目的观察急性心肌梗死(AMI)患者急性期24h动态血压变化。方法应用24h动态血压监测仪分别对8例AMI急性期患者、12例不稳定性心绞痛患者和12例正常对照者进行24h动态血压监测(ABPM)。结果AMI与不稳定性心绞痛比较:24hSBP、24hDBP、dSBP、dDBP、nSBP、nDBP均降低,差异有统计学意义(P<0.05);与正常对照者比较:24hSBP、24hDBP、dSBP、dDBP均降低,差异显著(P<0.05);并且AMI的血压昼夜节律消失。结论对AMI患者急性期应密切监测血压变化,合理使用药物。

Objective To observe the changes of 24h ambulatory blood pressure（ABP） in patients with a first acute myocardial infarction（AMI）. Methods 24h ABP was monitored in 8 patients with a firs AMI、 12 patients with unstable angina（UA） and 12 normotensives with ambulatory blood pressure recorder. Results Compared with the UA, there were all lower in 24hSBP、 24hDBP、 dSBP、 dDBP、 nSBP, nDBP in the AMI. The difference is significant（P〈O. 05）.Compared to the control, there were all lower in 24hSBP、 24hDBP, dSBP、 dDBP in the AMI. The difference is significant（P（O. OS）.And the circadium rhythm of BP in the AMI was disappeared. Conclusion The changes of ABP should be carefully monitored in patients with a first AMI. And a drug should be used reasonably.
