1 A rising heart rate does not cause your blood pressure to increase at the same rate. 2  Even though your heart is beating more times a minute, healthy blood vessels dilate (get larger) to allow more blood to flow through more easily.
High blood pressure can affect your health in four main ways: 1  Hardening of the arteries. 2  Pressure inside your arteries can cause the muscles that line the walls of the arteries to thicken, thus narrowing the passage. 3  A heart attack or stroke can occur if a blood clot blocks blood flow to your heart or brain. Enlarged heart. 2  High blood pressure increases the amount of work for your heart. 3  Like any heavily exercised muscle in your body, your heart grows bigger (enlarges) to handle the extra workload. 4  The bigger your heart is, the more it demands oxygen-rich blood but the less able it is to maintain proper blood flow.
