Blood Pressure Management for Infrarenal Aortic Dissection

Initial Management Approach

The European Society of Cardiology recommends immediate anti-impulse therapy targeting systolic blood pressure <120 mmHg and heart rate ≤60 beats per minute for all aortic dissections, including infrarenal cases 1
Intravenous beta-blockers, such as labetalol or esmolol, should be used as first-line agents due to their ability to reduce the force of left ventricular ejection, as recommended by the European Heart Journal 1, 2
Invasive monitoring with an arterial line and continuous ECG recording is essential, with admission to an intensive care unit, according to the European Heart Journal 1, 3
Adequate pain control is necessary to achieve hemodynamic targets, as stated by the European Heart Journal 1

The European Heart Journal recommends beginning with intravenous beta-blockers, such as labetalol or esmolol, to achieve heart rate control ≤60 bpm 1, 2
If beta-blockers alone are insufficient to reach target blood pressure, the European Heart Journal suggests adding intravenous vasodilators, such as calcium channel blockers or nitrates 1, 2
Non-dihydropyridine calcium channel blockers, such as diltiazem or verapamil, should be considered if beta-blockers are contraindicated, as recommended by the European Heart Journal 1

After 24 hours of stable hemodynamics with IV medications, the European Heart Journal recommends transitioning to oral beta-blockers and other antihypertensive agents if gastrointestinal transit is preserved 1
Long-term blood pressure control should target <135/80 mmHg, with beta-blockers as the preferred agents, according to the European Heart Journal 4

The European Heart Journal states that the same blood pressure targets apply to infrarenal dissections to prevent propagation 4

Regular imaging surveillance is necessary to detect progression of dissection or aneurysm formation, as recommended by the European Heart Journal 4
MRI is the preferred technique for follow-up studies as it avoids radiation exposure and nephrotoxic contrast agents, according to the European Heart Journal 4
Specialized physicians with knowledge of aortic dissection should follow patients to detect signs of disease progression, as stated by the European Heart Journal 4

The European Heart Journal warns against using vasodilators alone without prior beta-blockade, as this can increase aortic wall stress through reflex tachycardia 1, 2
The European Heart Journal advises against using dihydropyridine calcium channel blockers without beta-blockers due to risk of reflex tachycardia 2
Controlling dP/dt is crucial to prevent dissection propagation, and beta-blocker administration should not be delayed, as recommended by the European Heart Journal 2
Excessive blood pressure lowering should be avoided, as it may compromise organ perfusion, according to the European Heart Journal 2
