Normal human blood pressure is 140/90mmHg or less, i.e. systolic blood pressure <140mmHg and diastolic blood pressure <90mmHg are in the normal blood pressure range. However, if the patient's blood pressure is above 130mmHg, the cause should be determined according to the systolic or diastolic blood pressure and treated accordingly.1. Systolic blood pressure: If the systolic blood pressure is higher than 130mmHg and lower than 140mmHg, it may be due to the abnormal blood discharging function of the heart, resulting in the increase of blood in the peripheral blood vessels and high systolic blood pressure, but still in the normal range. Usually you need to pay attention to a diet with less salt and oil, and do appropriate exercise, such as walking and jogging, etc. You also need to monitor your blood pressure several times, and no special treatment is needed. However, it is recommended to control the systolic blood pressure below 130 mmHg, so as not to induce cardiovascular and cerebrovascular diseases; 2. Diastolic blood pressure: If the diastolic blood pressure is mainly above 130 mmHg, this condition is usually called hypertensive emergencies, often due to small blood vessel spasm resulting in elevated diastolic blood pressure, but also accompanied by elevated systolic blood pressure. Symptoms such as dizziness, headache, palpitations, chest tightness, etc., may occur. Intravenous antihypertensive drugs such as uradil and sodium nitroprusside need to be applied in hospital, and oral antihypertensive drugs such as metoprolol succinate and amlodipine besylate should be added to control diastolic and systolic blood pressure in the normal range to avoid dangerous events such as acute heart failure, acute cerebral infarction and cerebral hemorrhage. In addition, daily adjustment of dietary structure, such as less salt, less oil, light diet, proper exercise, weight reduction, avoiding late nights, relaxation and other measures can help control blood pressure stability. However, for hypertensive patients who need pharmacological intervention, and when blood pressure control is not satisfactory with a single drug, early combination of drugs or application of compound preparations for antihypertensive treatment is more effective.
