Abstract:
Objective This study aimed to explore the correlation and differences between invasive blood pressure(IBP)measured through the radial artery and non-invasive blood pressure(NIBP)measured through brachial artery in middle-aged and elderly patients undergoing percutaneous coronary intervention.Methods A total of 226 middle-aged and elderly percutaneous coronary intervention patients who underwent IBP and NIBP measurement in the Department of Cardiovascular Medicine of this hospital from April 2023 to April 2024 were selected as the research subjects.The systolic blood pressure(SBP)and diastolic blood pres-sure(DBP)of IBP and NIBP were recorded,and the correlation and consistency of blood pressure values be-tween IBP and NIBP were analyzed.Results Pearson correlation analysis showed that there was a positive correlation between SBP of IBP and SBP of NIBP(r=0.755,P＜0.001)and between DBP of IBP and DBP of NIBP(rs=0.803,P＜0.001).Further analysis of the difference in blood pressure values measured by NIBP and IBP revealed that the difference between SBP of NIBP and SBP of IBP was(-21.19±26.29)mmHg,with a 95％limit of agreement(LoA)of-47.50-5.11 mmHg;The difference between DBP of NIBP and DBP of IBP was(0.27±14.38)mmHg,with a 95％LoA of-14.10-14.65 mmHg.There were correlations between SBP and DBP measured by IBP and NIBP,respectively,in both male and female patients,with corre-lation coefficients≥0.73,and the differences were statistically significant(P＜0.001).There were correla-tions between SBP and DBP measured by IBP and NIBP,respectively,in both the age＜60 years group and age≥60 years group,with correlation coefficients≥0.73,and the differences were statistically significant(P＜0.001).Conclusion During coronary artery surgery,there is a positive correlation of blood pressure val-ues between IBP and NIBP in middle-aged and elderly patients.
