目的临床分析冠心病合并高血压24 h动态血压特征。方法 86例高血压患者,根据有无冠心病分为对照组(无冠心病)36例与观察组(合并冠心病)50例。均实行24 h动态血压监测,分析监测结果。结果 22:00~6:00时段,两组患者收缩压、舒张压水平比较,差异有统计学意义(P<0.05);观察组血压昼间节律消失率、晨峰出现频率均高于对照组,差异有统计学意义(P<0.05)。结论患者动态血压变异性直接影响冠心病的发生,且冠心病合并高血压患者的血压昼夜节律消失、晨峰增加较明显。
Objective To analyze the characteristics of ambulatory blood pressure in patients with coronary heart disease complicated with hypertension at 24 hours. Methods Totally 86 hypertensive patients were divided into control group (no coronary disease) and observation group (50 cases with coronary heart disease) according to the presence or absence of coronary heart disease. 24 h ambulatory blood pressure monitoring were implemented to analyze the monitoring results. Results The systolic blood pressure and diastolic blood pressure were significantly different between the two groups at 22:00 ~ 6:00 (P <0.05). The disappearance rate of blood pressure and the frequency of morning peak in the observation group were higher than those in the control group , The difference was statistically significant (P <0.05). Conclusion The dynamic blood pressure variability of patients directly affects the occurrence of coronary heart disease, and the circadian rhythm of blood pressure disappears in patients with coronary heart disease complicated with hypertension, the morning peak increases obviously.
