Malignant Hypertension: Definition, Symptoms, Tests and Treatment

This is a serious condition that requires immediate attention.

Rapid treatment can prevent long-term problems. Without treatment, the damage of malignant hypertension occurs rapidly and can be severe organ damage, involving blood vessels, eyes, heart, spleen, kidneys and brain.

A more technical term for this type of hypertension is: malignant hypertensive

In particular, you can develop kidney failure because the blood vessels in the kidneys are very sensitive to high blood pressure.

In addition to having high blood pressure and ailments, the development of malignant hypertension includes:

  • History of renal disorders or insufficiency.
  • Certain drugs or medications, including cocaine, amphetamines, monoamine oxidase inhibitors (MAOIs), and oral contraceptives.
  • History of vascular diseases.
  • Pregnant women with preeclampsia and eclampsia.
  • Feocromocitoma.
  • Disorders of the spinal cord.
  • Coarctation or dissection of the aorta.
  • Stenosis of the renal artery or narrowing of the arteries of the kidneys.
  • Missing doses of prescribed antihypertensive medications, especially beta-blockers or clonidine, which can cause a rebound effect. Breach of medication is the most common reason for hypertensive emergencies.

The malignant hypertensive is more common in African American men and smokers. You are more likely to develop malignant hypertension if you already have essential hypertension, high blood pressure of 140/90 or more.

The notable symptoms for this disease are:

  • Chest pain.
  • Difficulty breathing.
  • Headache.
  • Visual problems.
