Does blood pressure rise when there is exertion?
Your circulatory system maintains pressure in your arteries and your heart pumps against it. Blood pressure numbers reflect your arterial pressure when your heart pushes blood through your system, and also when your heart rests between beats. The "active" pressure is the top number on your blood pressure reading. It is the "systolic" pressure. The "passive," or "resting," pressure is the bottom number, and represents the "diastolic" pressure. Healthy blood pressure numbers are 120 systolic over 80 diastolic, or slightly lower Blood pressure changes throughout your day, depending on your position, your anxiety level, and your activity level. Chronic high blood pressure increases your risk of cardiovascular disease and stroke, but temporary increases in blood pressure allow you to meet the demands you put on your body when you exercise. Without adequate pressure, your blood delivery system fails. so,yes !!

If the 'right heart' fails, the part of the heart that moves blood from the body to the lungs for oxygenation, then there may be edema (swelling) in the body's extremities.
