Hypertension is a common, prevalent disease with mature treatment and management protocols. However, patients must follow strict guidelines to facilitate disease control. Many people wonder why hypertensive patients still need to take blood pressure-lowering medicine when their readings stay within normal range. Here is the detailed reasoning.
Reasons for Continuing Antihypertensives Despite Normal Blood Pressure
Long-standing hypertension, coronary heart disease, pulmonary heart disease and other conditions overburden or damage heart muscle tissue, triggering ventricular remodeling. This significantly raises risks of arrhythmia, heart failure and sudden cardiac death.
Certain antihypertensive drugs including ACEIs (Angiotensin-Converting Enzyme Inhibitors) and beta-blockers deliver dual benefits: they lower blood pressure, and also prevent or reverse ventricular remodeling, stopping cardiac function deterioration and arrhythmia development.
Therefore, for patients with hypertension, coronary heart disease, pulmonary heart disease, cardiomyopathy or rheumatic heart disease who meet clinical medication criteria, doctors will prescribe these so-called "antihypertensive drugs" even if blood pressure is normal. The core goal is not blood pressure reduction, but to curb ventricular remodeling and delay the onset and progression of heart failure.
Standard Procedures for Home Blood Pressure Self-Monitoring
Pre-measurement preparations
Choose a quiet testing environment.
Refrain from strong tea, coffee, alcohol and strenuous exercise for at least 5–10 minutes of full rest before measurement.
Maintain a calm mood; empty the bladder before testing.
Measurement standards
Use an upper-arm blood pressure monitor (electronic or desktop mercury sphygmomanometer).
Align the monitor cuff at the same horizontal level as the heart; either sitting or supine posture is acceptable.
Remain silent and still during measurement: avoid talking, moving limbs or crossing legs.
Remove upper-arm clothing completely; do not wrap the cuff over fabric.
Measure three times daily (morning, noon, evening), with a 5-minute interval between each reading. Record the average systolic and diastolic pressure for physicians to evaluate blood pressure control.
Dietary Guidelines for Hypertensive Patients
Maintain balanced, light meals. Sodium in salt elevates blood pressure and weakens the efficacy of antihypertensive medication. Strict salt restriction is essential.
Consume moderate portions of whole grains, lean meat, high-protein foods, vegetables, fruits and calcium-rich dairy products; prioritize low-calorie options.
Supplement potassium via oral potassium preparations or potassium-rich natural foods.
Cut high-calorie ingredients such as fat, refined sugar and pastries; moderately limit staple food intake and eat more high-fiber vegetables and fruits to prevent hypertension aggravation.
