At what level is malignant hypertension defined?

Malignant hypertension is characterized by significantly elevated arterial pressures that are associated with end-organ damage. This condition often presents not just with high blood pressure readings, but also with clinical manifestations reflecting damage to vital organs such as the kidneys, brain, and heart. The critical aspect of malignant hypertension is the presence of this organ damage, which distinguishes it from other forms of hypertension that may not have the same level of severity or complications.

The other options focus on specific numerical thresholds of blood pressure without addressing the crucial element of end-organ damage, which is essential for the diagnosis of malignant hypertension. Thus, defining malignant hypertension as an elevated arterial pressure associated with end-organ damage captures the seriousness and clinical implications of the condition effectively.
