Blood pressure is one of the four major vital signs, the others being heart rate, breathing rate, and body temperature. These vital signs can help give a general idea of how well the body and its organs are performing.

Other strokes are caused by bleeding into brain tissue when a blood vessel bursts (hemorrhagic stroke). Because stroke occurs rapidly and requires immediate treatment, stroke is also called a brain attack.
