An alternative to Heart Transplant

Thursday, February 25th, 2010

Why reconstructing a patient’s own heart better tan replacing it with a new one. Now, you may not have to join the long queue for a donor heart to replace your own flagging one. A surgical procedure that fixes failing hearts may just save your life. A decade ago, a patient with a damage heart had no option but to wait for a heart donor. With the introduction of SVR, the list of heart transplant candidates has been trimmed down.

Now, a patient’s enlarged heart can be made smaller and remodeled from a round shape to its natural pear shape. It is essential to reduce the size and shape of the heart as close as possible to the original to make it work properly again. Think of it as an overhauled engine. It is better to live with your own rebuilt heart than with another person’s organ, which requires medications that compromise immunity.

There are lots of shades to choose from, varying in color, size, shapes and style. What important health points should I remember when buying a pair of sunglasses? A sunglasses or shades were invented to provide the wearer visual comfort in very bright light. How dark the tint should be would depend on how much you want to reduce the outdoor brightness. Aside from visual comfort, sunglasses also serve to protect you from the sun’s harmful ultraviolet radiation.

Most sunglasses these days already have built-in UV protection. Note that UV protection is independent of tint-darker tint does not equal better UV protection. Most sunglasses have a sticker or tag indicating a UV protection feature. Sunglass frame should fit close to your face for better UV protection and shouldn’t slip off your nose, pinch your temples of ears or be too heavy. For drivers constantly exposed to glare, polarized lenses are good choice.
