Yale Medicine: ‘What Causes Heart Failure?’

The heart is a muscle and it’s main job is to pump blood but certain things can cause that muscle to fail. There are genetic reasons, there are reasons related to valve disease, and there’s a viral infection that affects the heart called myocarditis.

The most common cause of heart failure is a heart attack. Fatty plaque builds up in the blood vessel that supplies the heart itself and unless that blood vessel is opened up immediately that muscle will die. The rest of the muscle that’s not dead anymore has to do extra to keep on pumping the blood and overtime it cannot keep and that’s when heart failure develops.

Medical Views: ‘Macular Degeneration Research’

Macular degeneration is a leading cause of visual impairment in people over 65 and can lead to blindness. One in three people will eventually suffer some degree of macular degeneration, which is caused by abnormal blood vessels under the retina, the light-sensitive part of the eye. We treat both the more common “dry” as well as the more dangerous “wet” forms of macular degeneration. While there is currently no cure for this disease, we offer the latest treatments to reduce the risk of vision loss and blindness. These include anti-VEGF drugs—which attack proteins that create the abnormal blood vessels that cause macular degeneration—and photodynamic therapy, in which patients ingest medication that is then activated with a laser.
