Essential hypertension
Hypertension can be divided into two categories: primary and secondary. In the vast majority of patients, the cause of hypertension is unknown, which is called primary hypertension, accounting for more than 95% of all hypertensive patients; primary hypertension, also known as hypertension, can cause symptoms related to hypertension itself. Long-term hypertension can also become an important risk factor for a variety of cardiovascular and cerebrovascular diseases, and affect the functions of important organs such as the heart, brain, and kidneys, and eventually lead to the failure of these organs.
