Medical Management of Atherosclerotic Ectasia of the Thoracic Aorta

Introduction to Management

The American College of Cardiology recommends initiating aggressive cardiovascular risk reduction with antihypertensive therapy, high-intensity statin therapy targeting LDL <70 mg/dL, antiplatelet therapy, and mandatory smoking cessation for patients with atherosclerotic ectasia of the thoracic aorta 1, 2, 3

The American College of Cardiology and American Heart Association guidelines recommend reducing blood pressure to the lowest tolerable point to minimize aortic wall stress 1, 2, 3
Target blood pressure goals are <140/90 mm Hg for patients without diabetes and <130/80 mm Hg for patients with diabetes or chronic renal disease 1, 2, 3
Beta-blockers should be first-line therapy as they reduce both blood pressure and the force of left ventricular ejection, thereby decreasing aortic wall stress 1, 2, 3

High-intensity statin therapy is strongly recommended for atherosclerotic thoracic aortic disease, with a target LDL cholesterol <70 mg/dL 1

Smoking cessation is a Class I recommendation and must be aggressively pursued, according to the American College of Cardiology 1, 2, 3
Complete smoking cessation, weight reduction for overweight or obese patients, moderation of alcohol consumption, and regular aerobic exercise are recommended 1, 2, 3

Comprehensive atherosclerotic risk factor management is essential, including optimizing glycemic control in diabetic patients and addressing all modifiable cardiovascular risk factors 1, 2, 3

Serial imaging with CT or MRI is required to monitor for progression of ectasia, as most thoracic aortic disease is asymptomatic and difficult to detect on physical examination 3

Avoid inadequate lipid lowering, as patients with atherosclerotic aortic disease require LDL <70 mg/dL 1
Do not neglect smoking cessation counseling, as this is a Class I recommendation with direct impact on disease progression 1, 2, 3

Atherosclerotic ectasia of the thoracic aorta is considered a coronary artery disease equivalent with >20% risk of cardiovascular events within 10 years 4
Patients with thoracic aortic atheromata have an 11.4-fold increased odds ratio for abdominal aortic aneurysms, indicating widespread atherosclerotic disease 5

High-intensity statin therapy targeting LDL <70 mg/dL with >50% reduction from baseline is strongly recommended 4
Smoking cessation is a Class I recommendation and must be aggressively pursued 4

If systemic NSAID unavoidable, naproxen may be safer for cardiovascular system than COX-2 selective agents, though still carries GI risks, and should be used for the shortest duration possible 4
