99/65 mmHg is a normal blood pressure. If this blood pressure occurs in a patient with hypertension who is taking antihypertensive medication, the patient is still hypertensive, but it just means that the blood pressure has been controlled with antihypertensive treatment. This blood pressure is ideal for most relatively young patients, but for some elderly patients there may be cases of low blood pressure. In the elderly, due to the presence of atherosclerosis, blood pressure sometimes needs to be maintained at a certain level to ensure adequate cerebral perfusion. Especially for elderly patients with hypertension, the process of lowering blood pressure should not be too fast or too low. The blood pressure should be controlled gradually as the patient can tolerate it. Blood pressure should not be lowered as much as possible, but should be individualized.
