What does a small margin between systolic&diastolic blood pressure mean?
Blood pressure is the force of blood moving through the arteries in your body. When a person’s blood pressure is taken, it is measured by two numbers–the systolic pressure and the diastolic pressure. The systolic number is when the blood pressure is at its highest as the heart beats. The diastolic number means the heart is at rest. The difference between the two numbers is called pulse pressure.Narrow pulse pressureA narrow pulse pressure is usually indicative of shock caused by some kind of trauma, though there can be a number of causes.Causes of narrow pulse pressureThere are several things that can cause low or narrow pulse pressure, including shock, low stroke volume (low total blood volume) or low cardiac output. Some causes of shock include a heart attack, sudden blood loss due to an injury or a significant loss of body fluids.Additional causesAdditional causes include aortic stenosis (the incomplete opening of the aortic valve), anaphylaxis (allergic reaction), cardiac tamponad
