根据收缩压和舒张压增高幅度的不同,可以将老年高血压分为单纯性收缩期高血压和混合型高血压。顾名思义,单纯性收缩期高血压是指病人只有收缩压的增高(超过140mmHg),而舒张压的增高幅度远远低于收缩压的,甚至还低于90mmHg。这种单纯的收缩压增高占了老年高血压病人总数的一半以上, According to systolic blood pressure and diastolic blood pressure increase rate of different elderly hypertensive can be divided into simple systolic hypertension and mixed hypertension. As the name implies, simple systolic hypertension is the only increase in systolic blood pressure (more than 140 mmHg), while the increase in diastolic blood pressure is much lower than systolic blood pressure, even below 90 mmHg. This simple increase in systolic blood pressure accounts for more than half of the total number of elderly patients,
