[1] Carotid artery stenosis is a major risk ...
AFL is the second most common pathologic supraventricular tachycardia but occurs at a rate less than one-tenth of the most common supraventricular tachycardia (atrial fibrillation). [2] [3] The overall incidence of AFL has been estimated at 88 cases per 100,000 person-years. The incidence of AFL is significantly lower (~5 cases/100,000 person ...

The surgical mortality of endarterectomy ranges from 1–2% to as much as 10%. Two large randomized clinical trials have demonstrated that carotid surgery done with a 30-day stroke and death risk of 3% or less will benefit asymptomatic people with ≥60% stenosis who are expected to live at least 5 years after surgery.
Instead, it is most commonly associated with hemorrhage of small vessels in the cerebral cortex. [2] The strongest risk factor for intraparenchymal hemorrhage associated with cerebral amyloid angiopathy is old age, and cerebral amyloid angiopathy is most frequently seen in patients who already have, or will soon be diagnosed with, dementia .
