If it is a transient high blood pressure of 170 mmHg, it is considered to be a mismeasurement caused by a damaged instrument, high mood swings, etc., and requires several tests. If the systolic blood pressure is ≥170mmHg several times, it is considered to be grade 2 hypertension, which is not a very serious condition but needs to be taken seriously. Hypertension is clinically divided into primary hypertension and secondary hypertension. The goal of treatment for primary hypertension is to lower the blood pressure to normal (<140/90mmHg) or ideal level (<120/80mmHg), for young and middle-aged patients (<60 years old), patients with hypertension combined with renal disease should lower the blood pressure to below 130/80mmHg, and elderly people should try to lower it to 150/90mmHg. Therefore, for patients with hypertension Non-pharmacological treatment combined with pharmacological treatment can usually be used. Non-pharmacological treatment includes improving lifestyle and eliminating factors that are detrimental to physical and mental health, such as weight control, reducing dietary fat intake, limiting salt appropriately, maintaining proper exercise, quitting smoking and limiting alcohol, maintaining an optimistic attitude, and improving stress capacity. Drug treatment is naturally based on antihypertensive drugs, and commonly used antihypertensive drugs are usually divided into six categories, including diuretics, beta-blockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, angiotensin II receptor antagonists, and alpha-blockers. In addition, secondary hypertension is usually caused by renal disease, cardiovascular pathology and endocrine disease. In addition to hypertension treatment, active treatment of the primary disease, such as pharmacotherapy or surgery, is needed to help protect target organs and slow down the progression of hypertension in patients. In addition, in daily life, patients with hypertension should pay attention to regular blood pressure measurement, reasonable work and rest, and combination of work and rest. They should take their medications continuously as prescribed by their doctors and should not change or stop their medications at will. Active intervention in lifestyle can prevent the continuous aggravation of hypertension.
