Malignant hypertension is a complication of hypertension characterized by very elevated blood pressure, and organ damage in the eyes, brain, heart and/or kidneys. It is considered a hypertensive emergency.

The eyes may show retinal hemorrhage, or exudate. A diagnosis of malignant hypertension must show papilledema.

The brain shows manifestations of increased intracranial pressure, such as headache, vomiting, subarachnoid, and cerebral hemorrhage.

Patients will usually suffer from left ventricular dysfunction.

The kidneys will be affected, resulting in hematuria, proteinuria, and acute renal failure.

It differs from other complications of hypertension in that it is accompanied by papilledema.[2] This can be associated with hypertensive retinopathy.

Systolic and diastolic blood pressures are usually greater than 200mmHg and 140mmHg, respectively.
