Abstract：Objective To explore the application value of dynamic electrocardiogram and ambulatory blood pressure monitoring in patients with clinical renal hypertension.Methods From March to May 2018,74 patients with renal hypertension who were admitted to Shijiazhuang First Hospital were enrolled as observation group,75 healthy people were enrolled as control group.All patients had dynamic electrocardiogram and blood pressure monitoring.Ambulatory blood pressure,non-dipping blood pressure,ST-T change in electrocardiogram and arrhythmia were analyzed.Results Daytime and nocturnal systolic/diastolic blood pressure in observation group were significantly higher than those in control group [daytime systolic pressure:(158 ± 12) mmHg vs (126 ±6) mmHg,daytime diastolic pressure:(95 ± 7) mmHg vs (76 ± 5) mmHg,nocturnal systolic pressure:(154 ±12) mmHg vs (112 ± 4) mmHg,nocturnal diastolic pressure:(93 ± 7) mmHg vs (68 ± 3) mmHg];nocturnal systolic/diastolic blood pressure in control group were significantly lower than daytime blood pressure (all P ＜0.001);there were no significant differences between nocturnal and daytime blood pressure in observation group (all P ＞ 0.05).Incidence of non-dipping blood pressure in observation group was significantly higher than that in control group[71.6％ (53/74) vs 9.3％ (7/75)] (P ＜ 0.001).Incidences of ST-T change and arrhythmia in observation group were significantly higher than those in control group[16.2％ (12/74) vs 0,74.3％ (55/74) vs 8.0％ (6/75)] (both P ＜ 0.001).Conclusions Ambulatory blood pressure monitoring can reflect the changes of blood pressure throughout the day in patients with renal hypertension.Simultaneous dynamic electrocardiogram monitoring can identify adverse events such as myocardial ischemia and arrhythmia.
