180mmHg/120mmHg is a blood pressure reading indicating a systolic pressure of 180mmHg and a diastolic pressure of 120mmHg, classifying it as stage 3 hypertension. The specific details are as follows:

Blood pressure typically refers to the lateral force exerted by blood against the walls of blood vessels during circulation and is influenced by factors such as age and basal metabolism. Normally, the range for systolic pressure falls between 90mmHg and 139mmHg, while diastolic pressure ranges from 60mmHg to 89mmHg. Therefore, a blood pressure reading of 180mmHg/120mmHg indicates a severe condition, classified as stage 3 hypertension. Particularly when blood pressure suddenly rises due to emotional stress or excessive fatigue, it poses a risk of hypertensive emergencies. This can lead to damage in vital organs such as the heart, brain, and kidneys, potentially resulting in conditions like cerebral hemorrhage and acute heart failure.

Under the guidance of a medical professional, the patient may be prescribed medications such as amlodipine besylate and controlled-release nifedipine to manage their condition. It is also important for the patient to maintain a positive mindset and avoid emotional stress in their daily life.
