According to the classification of blood pressure, the blood pressure of 190/80mmHg belongs to simple systolic hypertension. Diuretics, calcium channel blockers, beta receptor antagonists, angiotensin-converting enzyme inhibitors, or angiotensin II receptor antagonists may be considered to control blood pressure on a case-by-case basis. Hypertension is defined as a blood pressure ≥140/90 mmHg measured on three separate days in adults without the use of antihypertensive medications; if only the systolic blood pressure is ≥140 mmHg and the diastolic blood pressure is <90 mmHg, it is called simple systolic hypertension. Its main characteristics are increased high pressure, decreased low pressure, increased pulse pressure; postural hypotension and postprandial hypotension are mostly caused by large fluctuations in blood pressure; there can also be abnormal changes in the circadian rhythm of blood pressure, and pseudohypertension is relatively common. Therefore, the treatment of simple systolic hypertension should avoid excessive and rapid reduction of blood pressure while the systolic blood pressure reaches the standard. At this time, calcium channel blockers can be used, common drugs such as nifedipine, amlodipine, etc. In order to ensure a smooth and sustained decline in blood pressure, long-acting extended-release agents can be chosen, such as nifedipine extended-release tablets or levamlodipine benzenesulfonate. Long-acting angiotensin-converting enzyme inhibitors or angiotensin II receptor antagonists, such as Benadryl, Valsartan, Irbesartan, and other drugs can also be chosen for control; in addition, diuretics or β-receptor antagonists can also be considered. Intravenous infusion of antihypertensive drugs such as uradil and sodium nitroprusside can be used for treatment when necessary. It is recommended that blood pressure abnormalities, under the guidance of the physician medication, to avoid delaying the condition.
