The danger of hypertension: hypertension is an abnormal increase in pressure in the arterial blood vessels, arterial blood vessels as the pipeline of water, the heart as the pump, the pressure in the pipeline is abnormally high, the pump will have to use greater force to pump the water into the pipeline, over time, the pump will be damaged by strain; the same reason, long-term hypertension if not timely and effective pressure reduction, the heart will be compensated for overwork and have hypertrophy and expansion, and then the function of Failure, which is hypertensive heart disease, heart failure; Similarly, the pressure in the pipeline is too high, the fragile hardened part of the pipeline is prone to burst, occurring in the cerebral vessels, is the hemorrhagic brain rate; Similarly, the kidney is extremely rich capillary network, this microscopic pipeline in the long-term high pressure under the influence of hardening, narrowing, functional damage, so that the kidney capillary network to exclude toxic substances in the body is impaired, the body Toxic substances are stored in the blood, which becomes renal failure and uremia. As the above simplified metaphor, if hypertension is not effectively controlled in time, the heart, brain and kidneys will suffer fatal blows to the three important vital organs, resulting in serious complications, such as: heart: hypertensive heart disease, coronary heart disease, heart failure; brain: hypertensive brain hemorrhage, cerebral infarction; kidney: renal failure, uremia. But when these problems occur, it will be futile for doctors or patients and their families in terms of energy, financial resources and physical strength spent.
