While it's true that some areas of cardiac muscle will start to die during a heart attack because of a lack of blood, a person's pulse may become slower (bradycardic) or faster (tachycardic), depending on the type of heart attack they're experiencing (a normal heart rate is between 60 and 100 beats per minute).

Effects of exercise on blood pressure Your muscles need more oxygen than they do when you're at rest, so you have to breathe more quickly. Your heart starts to pump harder and faster to circulate blood to deliver oxygen to your muscles. As a result, systolic blood pressure rises.

When blood flow is restricted or blocked completely, the heart muscle is starved of oxygen. This leads to a heart attack. During a heart attack, blood pressure can go up, down, or remain constant, depending on how the body responds.

When the heart pushes blood around the body during systole, the pressure placed on the vessels increases. This is called systolic pressure. When the heart relaxes between beats and refills with blood, the blood pressure drops. This is called diastolic pressure.
