Khảo sát sự biến thiên huyết áp ở bệnh nhân hẹp động mạch thận tại Bệnh viện Tim Hà Nội năm 2019

Abstract

Objective: to evaluate blood pressure variability in patients with renal artery stenosis using 24-hour blood pressure Holter. Subject and method: A cross-sectional description study on 41 patients diagnosed with moderate-severe renal artery stenosis and hypertension at Hanoi Heart Hospital from January 2019 to January 2020. Result: Mean values of systolic and diastolic blood pressure (nighttime and 24 hours) reached the diagnostic level of hypertension according to ESC. The standard deviation of systolic and diastolic blood pressure in patients with renal artery stenosis was increased. The proportion of patients with low blood pressure was 9.76%, without low blood pressure was 80.48%, and there was often non-dipper blood pressure at night. The time of blood pressure overload during the day was 55.90% and at night was 80.50%. The blood pressure variability indexes had no difference between the moderate and severe stenosis groups, and between the unilateral and bilateral renal artery stenosis groups. Conclusion: The blood pressure variability indexes of patients with renal artery stenosis were very high, therefore patients with renal artery stenosis should have their blood pressure monitored regularly every 24 hours and coordinate and distribute the dosage of drug groups into the appropriate times of day to control blood pressure better.
