Effects of antihypertensive treatment on cerebral perfusion

摘要: Antihypertensive treatment reduces the risk of ischemic strokes and cerebral hemorrhage as complications excessive or long-standing hypertension. However, neurologic dysfunction brain damage may also accompany short-term, under certain conditions, even long-term antihypertensive treatment. Therefore, should be instituted restrictively cautiously. Special regard given to action drugs on perfusion in patients with an increased for development treatment-induced complications, such hypertensive encephalopathy autonomic dysfunction, elderly suspected sclerotic stenosis neck arteries. The structural functional lesions vessels observed acute chronic hypertension are reviewed, effects blood flow. Calcium channel blockers angiotensin-converting enzyme inhibitors have advantages first-line elevated hypoperfusion, because selective these agents vasoconstricted their differential varying regional vascular beds. excellent efficacy short- lead changes traditional management emergencies well strategies other at complications.
