原发性高血压患者冠状动脉造影术前水化对血压的影响

Impact of hydration on blood pressure in patients with primary hypertension before coronary angiography

目的探讨原发性高血压患者行冠状动脉造影术前水化对血压的影响。方法选取行冠状动脉造影术的患者220例,根据估算的肾小球滤过率(eGFR)分为水化组及对照组,水化组术前12 h开始行水化治疗,测量所有患者术前12 h及术前即刻血压。结果水化组术前即刻血压较术前12 h血压明显升高;对照组术前即刻血压与术前12 h血压比较未见明显改变。结论原发性高血压患者冠状动脉造影术前水化可导致血压升高,应根据导致血压升高的原因采取综合措施降压,避免血压升高影响冠状动脉造影手术及增加不良事件的发生。

Objective To investigate the impact of hydration on blood pressure in patients with primary hypertension before coro- nary angiography. Methods A total of 220 patients undergoing coronary angiography were divided into two groups： hydration group and control group on the basis of estimated glomerular filtration rate. The hydration group received hydration therapy 12 hours earlier before angiography. The blood pressure of the patients was measured 12 hours earlier before angiography and immediately before an- giography. Results The blood pressure of the hydration group was elevated immediately 12 hours earlier before angiography, but that of the control group was not elevated. Conclusion Hydration therapy can elevate the blood pressure in hypertensives before coronary angiography. The composite depressurization therapy can reduce the impact of hypertension on coronary angiography and the adverse events caused by hypertension.
