How High Blood Pressure Can Lead to Heart Failure
Heart failure is when your heart is unable to pump enough blood to the body. It can happen quickly or take years to develop. Heart failure is caused by many factors, including the thickening and/or stiffening of the heart’s walls and blood vessels that have become narrow from uncontrolled high blood pressure.
- High blood pressure adds to your heart’s workload: When arteries become narrow and less flexible, it’s harder for blood to travel throughout your body. This causes your heart to work harder.
- Over time, a higher workload leads to an enlarged heart: To deal with increased demands, the heart muscle thickens and becomes larger. The heart can still pump blood, but it becomes less efficient. The larger the heart becomes, the harder it works to meet your body's demands for oxygen and nutrients.
