Objective

We sought to observe the difference in blood pressure in severe hypertensive patients undergoing carotid artery stenting (CAS) upto one year follow-up.

Background

Renal artery stenting controls blood pressure in some patients, is well known. However, blood pressure control after CAS has not been well explored.

Design/Methods This was a single-centre, observational study performed in patients undergoing CAS at a Tertiary care centre in India. Of total 720 patients who underwent CAS, 590 (82%) patients were hypertensive. These 590 patients were monitored for one year for the difference in blood pressure and medication requirements.

Results Of 590 patients, majority had blood pressure above 170 mm Hg, requiring 3 to 4 anti-hypertensive drugs. Following CAS 75% of the patients having hypertension got controlled in immediate post-procedure period. Of these, 38% of the patients didn’t require any anti-hypertensives upto 1 year follow-up and the remaining patients required single drug or 2 drugs.

Conclusions

We observed a unique finding that patients with severe hypertension requiring 3 to 4 drugs having severe carotid stenosis had blood pressure controlled with minimal or no drugs following CAS upto one year follow-up. The phenomenon behind this is probably the baroreceptor resetting. However, a trial on larger group of patients with longer follow-up will further support this finding.
