The severity of hypertension is not only related to blood pressure grading, but also to whether hypertension is accompanied by complications or risk factors, so it is not possible to grade severity based on blood pressure grading alone.
In clinical practice, the severity of hypertension is determined by the combination of blood pressure grading, the presence of risk factors or organ damage, and the presence of complications. For example, Grade 1 simple hypertension is a low-risk condition, while Grade 1 hypertension with diabetes mellitus or damage to organs such as the heart, brain, and kidneys is a high-risk condition.
Grade 3 hypertension is a high risk condition even if there are no complications and no target organ damage, and requires immediate standardized clinical treatment.
Therefore, it is difficult to determine the severity of hypertension based on the blood pressure classification alone, and it is recommended to go to the hospital as soon as possible to clarify the cardiovascular risk classification and standardize the treatment under the guidance of the doctor.
