What is hypertension risk rating scale?

High blood pressure is generally divided into three levels according to the severity of the disease. Grade 1 hypertension systolic blood pressure is 140-159mmHg and diastolic blood pressure is 90-99mmHg. Grade 2 hypertension systolic blood pressure is 160-179mmHg and diastolic blood pressure is 100-109mmHg. Grade 3 hypertension systolic blood pressure is above 180mmHg and diastolic blood pressure is above 110mmHg. The risk degree of hypertension can be divided into four levels, namely low risk group, moderate risk group, high risk group and extremely high risk group. The low-risk group is generally younger than 55 years old and is grade 1 hypertension. The intermediate-risk group is between grade 1 and grade 2 hypertension with one or two risk factors. The high-risk group is grade 3 hypertension without risk factors. If it is grade 1-2 hypertension, it may be accompanied by more than three risk factors. The last high-risk group is grade 3 hypertension with more than one risk factor or target organ damage.
