The three-tiered prevention strategy for hypertension: from early intervention to complication management

Three levels of prevention for hypertension:
Primary prevention: For individuals with risk factors for hypertension but who have not yet developed the condition, effective preventative measures are taken to reduce the incidence rate. Specifically:

1. A healthy lifestyle. This includes limiting salt intake (no more than 10 grams per day), weight loss, a balanced diet, and reducing psychosocial stress. It also involves quitting smoking, limiting alcohol consumption, reducing high-fat and high-calorie foods, and engaging in more aerobic exercise such as walking, jogging, hiking, and cycling.

2. Appropriate exercise. Life depends on movement; as the saying goes, "running water never stagnates, and a frequently used door hinge never rusts." The human body, like a machine, needs constant movement to prevent "rusting." Exercise promotes metabolism in all organs, delaying organ aging. Physical exercise promotes blood circulation, reduces cholesterol production, increases energy expenditure, and aids in weight loss. The intensity and duration of exercise should vary from person to person, generally ranging from 30 to 60 minutes.

Secondary prevention: For individuals already diagnosed with hypertension, effective treatment measures are taken to prevent the condition from worsening and to prevent complications.

Early treatment of hypertension reduces risk factors for complications. If blood pressure cannot be controlled by non-pharmacological methods, medical attention should be sought promptly, and medication should be used rationally under the guidance of a doctor. Currently, commonly used antihypertensive drugs fall into six main categories: diuretics, beta-blockers, angiotensin-converting enzyme inhibitors, calcium channel blockers, alpha-blockers, and angiotensin II receptor antagonists.

The ideal antihypertensive drug for treating hypertension should be able to reverse the hemodynamic changes caused by hypertension, maintain good organ blood perfusion, prevent and reverse target organ damage, reduce the incidence and mortality of complications, improve overall health, ensure quality of life, not cause metabolic disorders, and have no adverse side effects. In my country, among untreated hypertensive patients, 70%–80% die from stroke, 10%–15% from coronary heart disease, and 5%–10% from renal failure. Compared with people with normal blood pressure, their average lifespan is shortened by 15–20 years. Drug-induced blood pressure reduction can effectively prevent and treat stroke, myocardial infarction, heart failure, and renal failure (uremia), and prevent the progression of hypertension.

When a patient's blood pressure is stable and there are no significant complications, appropriate exercise is permitted, such as brisk walking, jogging, cycling, swimming, tennis, rope skipping, and badminton. When a patient's blood pressure is poorly controlled or there are significant complications, only gentler exercises are allowed, such as walking, gymnastics, and Tai Chi.

Tertiary prevention: Providing emergency care for patients with severe hypertension to effectively prevent complications, while simultaneously implementing rehabilitation therapy.
