High blood pressure generally refers to hypertension, hypertension is a very common cardiovascular disease, blood pressure continues to rise will seriously affect the health of the body, easy to cause systemic small arteriosclerosis, but also may further affect the blood supply of tissues and organs, inducing a variety of adverse consequences, easy to the heart, brain, kidney, retina and other damage to varying degrees: 1, heart damage: blood pressure continues to rise, the heart blood displacement resistance will follow Increase in blood pressure, resulting in increased ventricular load, myocardial hypertrophy, compensatory enlargement of the heart cavity, resulting in a corresponding reduction in cardiac output, myocardial ischemia, increased oxygen consumption, and thus induced heart failure. The hypertensive state can also cause heart damage and produce arrhythmia; 2. Cerebrovascular damage: the pressure in the blood vessels is significantly increased, which can easily lead to spasm of small arteries in the brain, symptoms of headache and dizziness, and possible dull discomfort in the head. In addition, elevated blood pressure is likely to destroy the integrity of the intima, forming plaques and inducing acute stroke, such as cerebral hemorrhage and cerebral infarction; 3, kidney damage: the kidneys have many tiny blood vessels, the blood pressure on the inner wall of the blood vessels continues to rise, which may cause vascular sclerosis of the kidneys, leading to kidney damage, which will further affect the prognosis of hypertensive patients, forming a vicious circle, chronic renal failure is one of the long-term hypertension Chronic kidney failure is one of the serious consequences of long-term hypertension; 4, retinal damage: there are rich capillaries at the bottom of the eye, elevated blood pressure may trigger lesions in the retina or blood vessels at the bottom of the eye, causing symptoms of blurred vision, and in severe cases, even blindness.
