Hypertension is a clinical syndrome characterized by an increase in blood pressure in the arteries of the body circulation, which may be accompanied by functional or organic damage to the heart, brain, kidneys and other organs. This disease is one of the most common cardiovascular diseases. If early intervention and treatment can be provided, the long-term prognosis for patients is generally very optimistic. The common clinical manifestations of hypertension are dizziness, headache, and in some cases, blurred vision, epistaxis, and precordial discomfort. Others may be more tolerant of the hypertensive state and have no discomfort, but this is a very dangerous situation. This is a very dangerous condition because there is a high risk that acute cerebral hemorrhage or cerebral infarction may occur unknowingly. If the blood pressure is not controlled for a long time, the pressure load on the heart will be higher, and over time, hypertensive heart disease can develop, and even heart failure, and the patient can have difficulty in breathing, wheezing and other uncomfortable symptoms. Elevated blood pressure can accelerate atherosclerosis and can also induce the production of myocardial infarction. It can also cause a certain degree of kidney damage, which can lead to proteinuria in the early stages and even uremia in the later stages. Hypertension can also cause retinopathy, which can manifest clinically as bleeding in the fundus of the eye and blurred vision. Hypertension is not scary, but it is the complications that result from elevated blood pressure. Hypertension is not a difficult disease, as long as we actively work to control blood pressure, generally speaking, will delay the complications, or to avoid complications, hypertension ideal control of blood pressure range is systolic blood pressure at about 130 mm Hg, diastolic blood pressure at 80 mm Hg, relatively speaking is the ideal state of blood pressure.
