Damage to the spinal cord, an information superhighway that originates in the brain, is a very devastating injury that can lead to paralysis. Most people have heard of traumatic spinal cord injuries because the sudden tragedies grab headlines from time to time. But, few people have heard of spinal stenosis, a narrowing of the tube which shelters the spinal cord called the spinal canal (See Spine Anatomy 101 ). As the space tightens like a noose, this slow strangulation of the nerves in the spine can disrupt anyone’s life. Sara turned 68 years old last month. She has enjoyed good health and has been an avid golfer. But, lately she has noticed an aching pain in her legs that occurs when she is walking or standing. This new problem has really slowed her golf game down and has made it difficult for her to even do her own grocery shopping. The only way she can make it up and down the aisles is by leaning on the shopping cart because that eases her pain. Frustrated, she calls to ...
Definition Mitral stenosis is a heart valve disorder that involves the mitral valve. This valve separates the upper and lower chambers on the left side of the heart. Stenosis refers to a condition in which the valve does not open fully, restricting blood flow. Alternative Names Mitral valve obstruction Causes, incidence, and risk factors Blood that flows between different chambers of your heart must flow through a valve. The valve between the two chambers on the left side of your heart is called the mitral valve. It opens up enough so that blood can flow from one chamber of your heart (left atria) to the next chamber (left ventricle). It then closes, keeping blood from flowing backwards. Mitral stenosis refers to when the valve cannot open as wide. As a result, less blood flows to the body. The upper heart chamber swells as pressure builds up. Blood may flow back into the lungs. Fluid then collects in the lung tissue ( pulmonary edema ), making it hard to breathe. See also: heart failure . In a...
High blood pressure, diabetes, heart disease, and other risk factors should be treated.
If you smoke, you should stop.
Treatment of TIA (transient ischemic attack, "warning strokes") may prevent future strokes.
Aspirin therapy (81mg a day or 100mg every other day) is now recommended for stroke prevention in women under 65 as long as the benefits outweigh the risks. It should be considered for women over age 65 only if their blood pressure is controlled and the benefit is greater than the risk of gastrointestinal bleeding and brain hemorrhage .
