Blood pressure is the amount of blood the heart pumps and the amount of resistance to blood flow in the arteries.
High blood pressure or hypertension is a common disorder in which the pressure remains abnormally high. High blood pressure typically has no symptoms, but can lead to major health problems including stroke, heart failure, heart attack and kidney failure.
