Management of Hypertension in Patients with Abdominal Aortic Aneurysm (AAA)

Blood Pressure Goals

The American Heart Association recommends a target blood pressure of <130/80 mmHg for patients with AAA to reduce cardiovascular events and potentially slow aneurysm growth 1, 2
Antihypertensive medication is strongly recommended for patients with AAA and an average SBP ≥130 mmHg or DBP ≥80 mmHg to reduce the risk of cardiovascular events 2
A more intensive SBP goal of <120 mmHg, if tolerated, may provide additional benefits in select patients without diabetes who are not undergoing surgical aortic repair 1
Uncontrolled hypertension is a known risk factor for aortic rupture and dissection, making aggressive BP control essential 1

Beta blockers are recommended as the preferred antihypertensive agents in patients with AAA 1, 3
Beta blockers may help reduce shear stress on the aortic wall and potentially slow aneurysm growth 4
Agents that alter the renin-angiotensin system (ACE inhibitors or ARBs) have shown robust evidence in AAA management and can be used in combination with beta blockers 1, 2

Statin therapy is recommended for patients with AAA and evidence of aortic atherosclerosis 1
Smoking cessation is essential as smoking is a major risk factor for AAA development, growth, and complications 2

When using beta blockers, start at a low dose and gradually titrate upward to avoid sudden drops in blood pressure 3
For patients with concomitant conditions like chronic aortic insufficiency, consider agents that do not slow heart rate (avoid beta blockers in these specific cases) 3
