急性心肌梗塞昼夜节律(附506例临床分析)

Circadian rhythm of actue myocardial infarction:Clinical analysis of 506 cases

通过对我院3年来急诊室及 CCU 病房收治的506例急性心肌梗塞患者进行临床分析,指出急性心肌梗塞发病有明显昼夜节律。即:6Am—12Am 是急性心肌梗塞及其并发症心律失常、猝死的高发时间。一日内急性心肌梗塞及心律失常发病有二个高峰时间,即:6Am—12Am;6pm—12pm。β—受体阻滞剂可以延缓和减少急性心肌梗塞及其并发症心律失常、猝死的发生。

The authors analyzed 506 patients with acute my- ocardial infarction admitted to the CCU and the emergen- cy room of our hospital in the past three years. The results show that circadian rhythm is evident in acute myocardial infarction.The peak onset of acute my- ocardial infarction and is complication(arrhythmia)and sudden death is from 6Am to 12Am.The time from 6Am to 12Am and 6Pm to 12Pm is found to be the peak onset time of acute myocardial infarction and srrhythmia.β-re- ceptor blocking agent can postpone and reduce the occur- rence of acute myocardial infarction,its complication (arrhythmia)and sudden death.
