首先,老年高血压具有以下特点:(1)脉压差大老年人由于动脉硬化,血管阻力增加,形成收缩压(高压)高,舒张压(低压)低,脉压差(高压与低压间的差值)大的特点。这类病人宜选择钙拮抗剂、利尿剂和血管紧张素转换酶抑制剂或血管紧张素受体拮抗剂效果较好。钙拮抗剂能更明显地扩张血管, First of all, elderly hypertension has the following characteristics: (1) pulse pressure difference in older people due to atherosclerosis, increased vascular resistance, the formation of systolic blood pressure (high pressure), diastolic blood pressure (low pressure) low pulse pressure (high pressure and low pressure Difference) large features. Such patients should choose calcium antagonists, diuretics and angiotensin converting enzyme inhibitors or angiotensin receptor antagonists better. Calcium antagonists can more clearly dilate blood vessels,
