Could a blocked artery increase blood pressure?

Yes.: Narrowing or blockage of renal arteries causes the kidney involved to secrete the enzyme renin which activates the renin- angiotensin- aldosterone system (involved with fluid and blood pressure control). There are medications to treat the hypertension. If the high blood pressure cannot be controlled a renal artery stent may be required. Work with your primary care doctor and a nephrologist.

Yes: A blocked kidney artery, referred to as renal artery stenosis or occlusion, can sometime lead to renovascular hypertension. Interventions can possibly benefit in certain situation, whereas other times medical management is most appropriate. Workup can include ultrasound, CTA, MRA, catheter angiography, blood tests, & urine tests. If concerned about this possibility, see a vascular specialist.
