近些年,我国农村的疾病谱在逐渐改变,其中,心、脑血管病的发病率明显增高。高血压是心、脑血管病的主要易患因素之一,对老人的威胁极大。为此,在农村要注意掌握老年高血压的临床诊治特点。 老年高血压的临床表现有以下特点:1.由于动脉硬化血管壁的弹性降低,使脉压缓冲力下降,引起收缩压明显升高。故老年高血压以收缩期高血压为多见,舒张压正常或偏低,脉压增大。以往多强调舒张压升高在致病上的重要性,近期发现单纯收缩压升高对血管病尤其是脑血管病的关系更为密切。2.体位性低血压很常见,这是由于颈
In recent years, the spectrum of diseases in rural areas in our country has been gradually changing. Among them, the incidence of heart and cerebrovascular diseases is significantly higher. Hypertension is one of the major predisposing factors for the heart and cerebrovascular diseases and poses a great threat to the elderly. To this end, in rural areas should pay attention to master the clinical diagnosis and treatment of hypertension in elderly characteristics. The clinical manifestations of senile hypertension have the following characteristics: 1. The arterial sclerosis due to reduced elasticity of the vascular wall, so that pulse pressure buffer force decreased, causing systolic blood pressure was significantly higher. Therefore, elderly hypertensive systolic hypertension is more common, diastolic blood pressure is normal or low, pulse pressure increases. In the past more emphasis on the importance of diastolic blood pressure in the pathogenesis, the recent discovery of elevated systolic blood pressure alone, especially the relationship between vascular disease more closely. 2 orthostatic hypotension is very common, this is due to the neck
