Blood Pressure Control in Aortic Aneurysm

Blood Pressure Targets

  • The European Society of Cardiology recommends a systolic blood pressure target of <130 mmHg and diastolic blood pressure target of <80 mmHg for patients with aortic aneurysms, with consideration for more intensive lowering toward 120-129 mmHg if tolerated, to reduce cardiovascular events, aneurysm growth, and risk of rupture or dissection 1, 2, 3
  • For patients with abdominal aortic aneurysm (AAA), a primary target of SBP <130 mmHg and DBP <80 mmHg is recommended to reduce cardiovascular events, including myocardial infarction and stroke, and to prevent aneurysm rupture 2, 3, 4
  • Select patients with AAA without diabetes who are not undergoing surgical repair may benefit from intensive SBP control to <120 mmHg, based on SPRINT trial data showing a 25% reduction in cardiovascular events and a 27% reduction in all-cause mortality 2, 3, 4

Preferred Antihypertensive Agents

  • Beta blockers are recommended as first-line agents for achieving target blood pressure goals in thoracic aortic aneurysm (TAA) patients, regardless of cause, in the absence of contraindications 5
  • The American Heart Association recommends beta blockers for all patients with Marfan syndrome and aortic aneurysm to reduce the rate of aortic dilatation, based on randomized trial data showing attenuated expansion over 10-year follow-up 6, 7, 8
  • ACE inhibitors or ARBs may be considered in all patients with peripheral arterial disease, including aortic aneurysms, regardless of blood pressure levels, in the absence of contraindications 1

Special Considerations

  • The European Society of Cardiology advises that blood pressure should not exceed 130 mmHg systolic in patients with aortic dissection; this applies to both children and adults 9
  • For patients with ruptured AAA, maintaining SBP between 60-90 mmHg (permissive hypotension) is suggested to maintain mentation while minimizing bleeding prior to definitive repair 10

Clinical Pitfalls to Avoid

  • Uncontrolled hypertension is a known risk factor for aortic rupture and dissection; aggressive blood pressure control is essential even in asymptomatic patients 2, 3, 4
  • Combination therapy is usually required to achieve target blood pressure goals; beta blockers should be combined with ACE inhibitors or ARBs for optimal control 6, 9, 7, 8
