Abstract
Objective To investigate the correlation between the carotid pulse index and resistance index with ambulatory electrocardiographic blood pressure monitoring indicators in the patients with hypertension.Methods A retrospective analysis was conducted on 800 patients with essential hypertension diagnosed and treated in this hospital from January 2021 to January 2022.The patients were included in the study group.At the same time,300 healthy volunteers undergoing the physical examination were included in the control group.The carotid pulse index,resistance index,24 h average diastolic and systolic blood pressure,daytime and nighttime average diastolic and systolic blood pressure,24 h diastolic pressure load and 24 h systolic pressure load were monitored and compared between the control group and study group.The patients in the study group conducted the tertile grouping according to the pulse index and resistance index,and the correlation be-tween the carotid pulse index and resistance index with ambulatory electrocardiographic blood pressure moni-toring indicators in patients with hypertension was analyzed.Results The carotid pulse index,resistance in-dex,24 h mean diastolic pressure,24 h mean systolic pressure,daytime mean diastolic pressure,nighttime mean diastolic pressure,daytime mean systolic pressure,nighttime mean systolic pressure,24 h diastolic pres-sure load and 24 h systolic pressure load in the study group were higher than those in the control group,and the differences were statistically significant(P＜0.05);with the increase of carotid pulse index,the 24 h mean diastolic pressure,24 h mean systolic pressure,daytime mean diastolic pressure,daytime mean systolic pres-sure,24 h diastolic pressure load,24 h systolic pressure load in hypertensive patients were increased signifi-cantly,and the differences were statistically significant(P＜0.05);With the increase of resistance index,the 24 h mean diastolic blood pressure,24 h mean systolic blood pressure,daytime mean diastolic blood pressure,nighttime mean diastolic blood pressure,daytime mean systolic blood pressure,nighttime mean systolic blood pressure,24 h diastolic blood pressure load and 24 h systolic blood pressure load in hypertensive patients were significantly increased,and the differences were statistically significant(P＜0.05).The correlation analysis results showed that the carotid pulse index and the carotid resistance index was positively correlated with 24 h mean diastolic pressure,24 h mean systolic pressure,daytime mean diastolic pressure,daytime mean systolic pressure,24 h diastolic pressure load and 24 h systolic pressure load in hypertensive patients(r＞0.3,P＜0.001).Conclusion The changes of carotid pulse index and resistance index in hypertensive patients are posi-tively correlated with the ambulatory electrocardiographic blood pressure monitoring indicators such as 24 h mean blood pressure,daytime mean blood pressure and 24 h blood pressure load.With the increase of carotid pulse index and resistance index,some ambulatory electrocardiographic blood pressure monitoring indicators are also increased correspondingly.关键词
