This differs from other hypertension complications. The systolic as well as diastolic blood pressures are greater than 120 and 240. Though the blood pressure shoots high, it is difficult to bring down the pressure immediately. In emergency cases, it is being done, yet in the case of urgency; it is not rushed to bring it down. Malignant hypertension deals with small arteries and necrosis of arterioles. The red blood cells get damaged as the vessels are obstructed by the deposition of fibrin and this result in serious anemia.
