RESUMO
Hypertension is an important risk factor for cardiovascular and cerebrovascular diseases,which can damage structure and function of vital organs such as the heart,brain and kidney.Pseudo hypertension (PHT) refers to the blood pressure measured by ordinary cuffmanometry is higher than that of the arterial puncture,which is an essential factor of refractory hypertension.Recent findings have suggested that the elderly patients with concomitant history of atherosclerotic disease,renal insufficiency,and diabetes mellitus have the highest risk of pseudohypertension.The incidence rate ofpseudohypertension is about 1.7％-50％ in domestic and international studies.In the clinical treatment,the misdiagnosis of hypertension of patients with excessive blood pressure will lead to severe perfusion defects.In this review,we will focus on the diagnosis and pathogenesis of pseudohypertension.
