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.

Outcome Measures

Primary Outcomes (1)

  • The incidence of persistent post-surgery hypotension

    systolic blood pressure (SBP) \< 90 mmHg or requiring vasopressor with lasting \> 6 hours, and without evidence hypovolemia and heart failure

    the first 24 hours after CAS

Secondary Outcomes (6)

  • Length of stay after surgery

    From surgery to dicharge, up to 3 month.

  • Hospital expenses after surgery, based on payment list in hospital information system

    From surgery to dicharge, up to 3 month.

  • Difference of serum catecholamine (adrenalin, norepinephrine and dopamine) before and after surgery (all in unit of nmol/L)

    at morning (7 o'clock am) of the day of surgery and the first day after surgery

  • Difference of heart rate variability (HRV) before and after surgery

    24 hours before surgery to at least 24 hours after surgery

  • The incidence of bradycardia after surgery

    the first 24 hours after CAS

  • +1 more secondary outcomes

Other Outcomes (1)

  • The total incidence of cardiac and cerebral events (stroke, myocardial infarction, heart failure and angina pectoris) and symptomatic hypotension

    From administering antihypertensive drugs to stenting, at least 5 days

Study Arms (2)

RASI group

EXPERIMENTAL

Administer RASI, with or without other antihypertensives except for CCB, and blood pressure should be controlled within the target range (140/90 mmHg). RASI intaking starts at least 5 days before stenting.

Drug: administering RASI (the trade name or universal name will not be stipulated) before stenting

CCB group

ACTIVE COMPARATOR

Administer CCB, with or without other antihypertensives except for RASI, and blood pressure should be controlled within the target range (140/90 mmHg). CCB intaking starts at least 5 days before stenting.

Drug: administering CCB (the trade name or universal name will not be stipulated) before stenting

Interventions

Pre-operative antihypertensive drugs before stenting will be random assigned (RASI or CCB) at least 5 days before stenting. Patients in RASI group will receive RASI (all kinds of RASI will be permited and the trade name or universal name of drugs will not be limited), with or without other antihypertensives except for CCB (any kind of CCB). Blood pressure of patients should be controlled within the target range (140/90 mmHg); and usage and dosage of antihypertensive drugs will not be stipulated. Grapefruit intaking should be avoid.
