The life expectancy of a 30-year-old patient with hypertension is related to a variety of factors, such as the control of blood pressure, damage to target organs, and individual physical tolerance, and varies widely among individuals. If patients can take antihypertensive drugs on time and in the right amount as prescribed by their doctors and keep their blood pressure within the ideal range, life expectancy is generally not affected. Hypertension can cause damage to the endothelium of the arteries, resulting in the deposition of lipids under the damaged endothelium and the gradual development of atherosclerosis. The progression of atherosclerosis can lead to narrowing and even occlusion of blood vessels. Therefore, it is very important for patients to control their blood pressure well. If blood pressure can be controlled below 130/80 mmHg, target organs can be protected and good vascular elasticity can be maintained, the patient’s life expectancy can be unaffected. Therefore, young hypertensive patients are advised to diagnose and treat early, monitor blood pressure, and give regular hypertension risk stratification to adjust medication. Daily attention should be paid to regular life, avoid staying up late, avoid over-excitement and over-exertion, quit smoking and alcohol, and relax.
