If the systolic blood pressure is 158 mmHg after correct measurement of blood pressure, it is considered to be hypertension, and the elderly are considered to be intermediate-risk hypertensive patients without combining risk factors other than age or damage to target organs or clinical comorbidities. Using sphygmomanometer to measure blood pressure correctly requires patients to rest in a quiet environment for 5~10min before measurement, the upper limb to be measured is usually the right upper limb, the elbow and the heart are at the same level, to ensure that the lower edge of the cuff in the elbow above the nest of 2~3cm, the cuff elasticity is appropriate to be able to reach into a finger is appropriate. Generally, the average value of 2~3 measurements is taken, and the interval between each measurement is 1~2min. According to the cardiovascular risk classification standard for hypertensive patients: patients with systolic blood pressure 158mmHg between 140~159mmHg belong to class 1 hypertension; on this basis, if there are no other risk factors or medical history, it is low-risk; if combined with 1~2 other risk factors, it is intermediate-risk; if combined with ≥3 other risk factors or target-organ damage, it is high-risk; if there are clinical comorbidities or diabetes mellitus, it is very high-risk. The “elderly” in the title are considered to be at very high risk. If the “elderly” in the title is >55 years of age for men or >65 years of age for women, that is 1 risk factor, and the patient is at least at intermediate risk for hypertension. In addition to age, cardiovascular risk factors include smoking, dyslipidemia, abdominal obesity, and family history of early-onset cardiovascular disease. Target organ damage includes left ventricular hypertrophy and atherosclerosis. Accompanying clinical diseases include cerebrovascular disease, cardiac disease, renal disease, diabetes, and so on. If the systolic blood pressure of the elderly reaches 158 mmHg after formal measurement, it is recommended to actively seek medical consultation and treatment to control blood pressure.
