Overview

Medical Therapy

Guideline on the Management of Patients With Extracranial Carotid and Vertebral Artery Disease: Treatment of Hypertension[1] (DO NOT EDIT)

Class I

  1. Antihypertensive treatment is recommended for patients with hypertension and asymptomatic atherosclerotic ECVD to maintain blood pressure (BP) less than 140/90 mmHg. (Level of Evidence: A)

Class IIa

Except during the hyperacute period, antihypertensive treatment is probably indicated in patients with hypertension and symptomatic atherosclerotic ECVD, but the benefit of treatment to a specific BP has not been established in relation to the risk of exacerbating cerebral ischemia. (Level ofEvidence: C)

Guideline on the Management of Patients With Extracranial Carotid and Vertebral Artery Disease:Control of Hyperlipidemia[1] (DO NOT EDIT)

Class I

  1. Treatment with a statin is recommended for all patients with atherosclerotic ECVD to lower lowdensity lipoprotein cholesterol to less than 100 mg/dL. (Level of Evidence: B)

Class IIa

  1. Treatment with a statin is reasonable for all patients with atherosclerotic ECVD who sustain ischemic stroke to reduce low-density lipoprotein cholesterol to a level less than or equal to 70 mg/dL. (Level of Evidence: B)
  2. If treatment with a statin does not achieve the goal, intensifying therapy with an additional drug from among those with evidence of improving outcomes can be effective. (Level of Evidence: B)
  3. For patients who do not tolerate statins, therapy with bile acid sequestrants and/or niacin is reasonable. (Level of Evidence: B)

Guideline on the Management of Patients With Extracranial Carotid and Vertebral Artery Disease: Management of Diabetes Mellitus in Patients With Atherosclerosis of the Extracranial Carotid or Vertebral Arteries[1] (DO NOT EDIT)

Class IIa

  1. Diet, exercise, and glucose-lowering drugs can be useful for patients with diabetes mellitus and extracranial carotid or vertebral artery atherosclerosis. The stroke prevention benefit, however, of intensive glucose lowering therapy to a glycosylated hemoglobin A1c level less than 7.0% has not been established. (Level of Evidence: A)
  2. Administration of statin-type lipid-lowering medication at a dosage sufficient to reduce LDL cholesterol to a level near or below 70 mg/dL is reasonable in patients with diabetes mellitus and extracranial carotid or vertebral artery atherosclerosis for prevention of ischemic stroke and other ischemic cardiovascular events. (Level of Evidence: B)
