Malignant Hypertensive Arteriolar Nephrosclerosis - Malignant Hypertension


Diagnosis & Tests

How is the disease diagnosed?

Malignant hypertension is diagnosed by a physical examination. An eye exam will show changes that signal very high blood pressure. A healthcare provider will also take a person's blood pressure. When blood pressure is measured, there are two numbers that are reported, for example, 140/90. The top number is the systolic blood pressure, and the bottom number is the diastolic blood pressure. An example of extremely high blood pressure is 220/140.

Other signs that a person has malignant hypertension include:

  • diastolic blood pressure that is always more than 120
  • signs of congestive heart failure and chronic renal failure
  • changes in mental status, such as confusion and memory loss
  • These signs indicate a medical emergency. Blood pressure must be controlled quickly to avoid permanent damage to internal organs and death.
