Patient: The patient was operated by you on February 29, 2008. Name of surgery: extracorporeal circulation Bentall + half arch replacement + CABG (aortic root – right coronary artery trunk)! Now my blood pressure is a little high, high pressure 160-170, low pressure is ok. I am currently taking two antihypertensive medications, Betaloc and felodipine, which are not very effective. What should I do? Song Zhigang, Department of Thoracic Surgery, Shanghai Changhai Hospital: This blood pressure is really high, betalac can be taken up to 150mg per day, felodipine can be taken up to 10mg per day, I don’t know how much you eat, but not enough can be added, if the amount is enough, you can add other antihypertensive drugs, such as Ritex, Coxsemol and other antihypertensive drugs, must be good to control blood pressure.
