A blood pressure of 190 mmHg is considered high risk. Clinically, the risk level of blood pressure level is stratified, such as blood pressure level ≥180/110mmHg belongs to the third level of hypertension, patients who reach the third level of hypertension itself belongs to the high risk, if at the same time combined with other risk factors, such as smoking, elevated blood lipids, family history of early onset cardiovascular disease, etc, belongs to the level of very high risk. Patients with grade 3 hypertension should be proactive in controlling their blood pressure levels to a safe range, but care should be taken to avoid lowering blood pressure levels too low and too fast, as this may lead to insufficient blood supply to the brain. Severe hypertension often requires a combination of medications, such as oral amlodipine plus valsartan, or in combination with metoprolol, as prescribed by your doctor.
