Purpose: Hypertension is closely related to the occurrence and aggravation of major incidents in cardiovascular system. However, there is not much elucidated about the accordance of blood pressure (BP) measurement with oscillometric device and invasice BP from patients having the risks of cardiovascular disease. We have checked the accordance of non-invasive BP using the oscillometric device in comparison with invasive BP through redial artery catheter in performing coronary angiography.
Subjects and methods: We compared the BP measured through redial artery and electronic sphygomanometer (Omron HEM-747IC, Japan) from the brachial for 104 patients who had gone through coronary artery angiography by visiting Chungbuk university hospital from September, 2007 till April, 2008.
Results: The BP measured with oscillometric device was mostly in accordance with invasive BP for all systolic, diastolic and average BP. However, the group of stage 1 hypertension by the standards of Seventh Report of the Joint National Committee showed low accordance between the two methods in diastolic BP. For non hypertension group and pre-hypertension group, systolic BP showed a pattern where systolic BP was underestimated, but for the first and second stage hypertension groups, the BP measured with oscillometric device displayed an overestimated patten
Conclusion: Most of the blood pressures measured with automated sphygomanometer showed good agreement with invasive BP. However, it needs attention in using because the diastolic BP is not in accordance with invasive BP form the first stage hypertension patients.
