The Variation Of Blood Pressure Measurements After Transradial Coronary Intervention

Objective:To explore the impact of transradial coronary interventional procedure on bloodpressure measurements.Methods:154patients undergoing interventional procedures via the right radial artery wereselected from our hospital.According to the angiographic results they were dividedinto normal group and disease group, and their general information was collected.Simultaneous measurement was performed to obtain the blood pressure values of thebrachial and radial arteries of both arms before the procedure and1day,7days,3months and≥6months after the procedure.Results:1. There were no significant differences between arms in preoperative systolicand diastolic blood pressures of the left and right brachial arteries in normal group(SBP：122.3±17.6mmHg vs122.4±17.9mmHg； DBP：70.6±10.0mmHg vs.71.0±10.1mmHg,P＞0.05); so it is in disease group (SBP：118.4±12.7mmHg vs.119.7±13.4mmHg；DBP：68.0±8.0mmHg vs.68.6±8.4mmHg,P＞0.05). There werealso no significant differences between arms in preoperative systolic and diastolicblood pressures of the left and right radial arteries in normal group(SBP：119.9±11.9mmHg vs.120.8±12.1mmHg；DBP：69.5±7.5mmHg vs.70.4±7.6mmHg,P＞0.05)and in disease group(SBP：121.6±10.5mmHg vs.122.5±10.1mmHg；DBP：70.8±6.2mmHg vs.71.3±6.8mmHg,P＞0.05).2. The data of the SBP and DBP measured1day after the procedure in right isinferior to the left neither the normal group(SBP：117.8±14.6mmHg vs.124.9±14.5mmHg；DBP：67.4±8.1mmHg vs.71.5±7.9mmHg,P＜0.05) nor pathology group(SBP：117.8±14.6mmHg vs.124.9±14.5mmHg；DBP：66.0±8.9mmHg vs.72.9±8.8mmHg,P＜0.05); the same as7days after the procedure of normal group(SBP：117.4±10.4mmHg vs.121.6±11.1mmHg； DBP：67.1±5.8mmHg vs.70.8±6.7mmHg, P＜0.05) and pathology group (SBP：113.0±8.9mmHg vs. 120.6±9.0mmHg；DBP：67.2±5.5mmHg vs.71.7±6.3mmHg,P＜0.05). There wereno statistics significant differences in systolic and diastolic blood pressures measured3months and≥6months after the procedure between the left and right brachialarteries (P＞0.05).3. There were significant differences in systolic and diastolic blood pressuresmeasured1day after the procedure of the left and right radial arteries in normal group(SBP：119.9±12.6mmHg vs.113.0±11.7mmHg; DBP:71.8±8.6mmHg vs.65.6±8.7mmHg,P＜0.05),the data measured7days after the procedure also revealedsignificant difference in normal group(SBP:118.3±8.7mmHg vs114.1±8.5mmHg;71.6±6.2mmHg vs.67.1±5.9mmHg,P＜0.05). The data of the SBP and DBPmeasured1day after the procedure (SBP:125.4±15.1mmHg vs.115.6±14.0mmHg;DBP:72.6±9.2mmHg vs.67.0±7.7mmHg,P＜0.05) and7days after the procedure(SBP：120.9±11.5mmHg vs.114.8±10.7mmHg,P＜0.05；DBP：71.6±7.4mmHg vs.68.3±7.0mmHg, P＜0.05) in left and right radial arteries revealed significantdifference in disease group. There were no significant differences in systolic anddiastolic blood pressures measured3months and≥6months after the procedurebetween the left and right brachial arteries (P＞0.05).Conclusions: After transradial intervention, the SBP and DBP of the brachialand radial artery in operative side was lower than contralateral side, especially indisease group, but this difference gradually decreases with time.
