Long-term hypertension has an impact on renal function, this is because long-term sustained hypertension increases glomerular endocapsular pressure, glomerular fibrosis, atrophy, and renal arteriosclerosis, leading to renal failure due to ischemia of the renal parenchyma and the continuous reduction of renal units. Hypertension is one of the important risk factors for cardiovascular and cerebrovascular diseases, long-term hypertension will damage the heart, brain, kidneys and systemic blood vessels and other organs, once the organ damage is difficult to reverse, will eventually lead to stroke, myocardial infarction, heart failure, renal failure, and other diseases, once the discovery of high blood pressure medication should be actively lowering blood pressure before it is too late, so that the blood pressure to achieve the standard in order to maximize the reduction of, and to delay the occurrence of renal failure and other conditions.
