Official Title: Pre-operative Antihypertensive Drugs and Persistent Hypotension in Carotid Artery Stenting Comorbid With Hypertension Patients --- a Multicenter, Randomized, Open Label, Blinded Ended Point Clinic Tra
Brief Summary: Carotid artery stenting (CAS) is one of major treatments in prevention of ischemic stroke.
Because of sinus reflex due to stenting and balloon dilatation, persistent post-surgery hypotension is a common perioperative event.
Persistent hypotension can lead to perioperative adverse events like ischemic stroke, myocardial infraction, renal failure and death; or more usually, it prolongs length of stay and hospital expenses.
Renin-angiotensin-aldosterone inhibitor (RASI) could inhibit the release of catecholamine and may lead to higher rate of persistent hypotension after CAS compared to other hypertensives.Thus, the investigators aim to investigate the effect of pre-operation antihypertensive drugs on persistent hypotension after stenting, and followed burden in carotid artery stenting comorbid with hypertension patients.
