In patients with primary or secondary hypertension, a sudden and significant increase in blood pressure under the action of certain triggers can clinically lead to hypertensive emergencies, hypertensive sub-emergencies, and malignant hypertension, and patients can all present with headaches and other symptoms. The doctor needs to decide the treatment plan according to the specific condition and combined with clinical auxiliary examination. 1.Brain damage induced by hypertensive emergencies, including hypertensive encephalopathy, intracranial hemorrhage (cerebral hemorrhage and subarachnoid hemorrhage), and cerebral infarction, patients will have different degrees of headache, and the degree of headache is not proportional to the blood pressure level. Patients need to arrive at the hospital as soon as possible, complete head CT or head MRI and other examinations, and be given antihypertensive treatment under the guidance of a doctor. In patients with intracranial hemorrhage or cerebral infarction, blood pressure should not be lowered to normal level in the acute stage, and dehydration and intracranial pressure lowering treatment should be given at the same time. 2. Patients with subacute hypertension, although their blood pressure is significantly elevated, are not accompanied by serious clinical symptoms and progressive target organ damage. It is recommended to control blood pressure gradually under the guidance of a doctor, and it is not advisable to lower blood pressure to normal level abruptly within a short period of time. 3, a few patients with diastolic blood pressure persistently ≥ 130 mmHg, the condition develops sharply into malignant hypertension, with prominent target organ damage, especially renal damage, and while controlling blood pressure, we should be careful of complications of heart, brain, kidney and fundus vessels. Timely and correct management of hypertensive headache is very important to bring the disease into remission as soon as possible in a short time, prevent progressive or irreversible target organ damage, and reduce the rate of disability and mortality.
