A gradual increase in blood pressure that remains high for a long period of time may lead to enlargement of the left atrium and the right ventricle, as well as the gradual development of heart failure. Hypertension itself can also induce the progression of atherosclerosis and aggravate the condition of coronary atherosclerotic heart disease. Hypertension can also lead to renal failure, uremia, and can lead to fundopathy and ultimately blindness, as well as cerebral infarction and cerebral hemorrhage. It is recommended that patients who have abnormal blood pressure must be actively given to improve the treatment. In order to slow down the progress of the disease and prevent complications caused by high blood pressure, it is also recommended that patients should find out what causes high blood pressure.
