收缩期高血压病指单纯收缩压增高(>160mmHg)(21.3kPa,1kPa=7.5mmHg)舒张压正常或稍低(<90～95mmHg)。此种病人随增龄而增多,妇女和黑人患病率可高达50％。有少数病人是由于主动脉瓣闭锁不全、甲亢、贫血、动静脉瘘、骨Paget氏病、脚气病等所致,故应注意检查鉴别。多年来都以舒张压作为预测心血管情况的指标,事实上舒张压与病人的转归联系不多,甚至全无关联,而收缩压的重要性却明显。以舒张压为标准的缺点是:
Systolic hypertension refers to a simple systolic blood pressure increase (> 160mmHg) (21.3kPa, 1kPa = 7.5mmHg) diastolic blood pressure normal or slightly lower (<90 ~ 95mmHg). Such patients increase with age, the prevalence of women and blacks up to 50%. A small number of patients are due to aortic valve atresia, hyperthyroidism, anemia, arteriovenous fistula, Paget’s disease, beriberi, etc., it should pay attention to check and identify. Diastolic pressure as a predictor of cardiovascular status over the years, in fact, diastolic pressure and the patient’s prognosis is not linked, or even no correlation, and the importance of systolic blood pressure is obvious. The diastolic pressure as the standard shortcomings are:
