Heart Doctor Pioneer Michael DeBakey Dies

Dr. Michael DeBakey, the famous cardiovascular surgeon that pioneered the bypass surgery and inventor of many devices to help people with heart problems, has died at the age of 99 from natural causes at the Methodist Hospital in Houston, TX. In 1932, while he was still in medical school, he invented the roller pump, which later became the most important part of the heart-lung machine. The machine takes over the responsibilities of the heart and lungs during surgery. He was also the pioneer in the development of artificial hearts and heart pumps to help people waiting for transplants. He had helped to create more than 70 surgical instruments in his lifetime.

In the 1950s, DeBakey was the first person to perform the replacement of arterial aneurysms and obstructive lesions. He had developed bypass pumps and connections to replace parts of diseased arteries.

He had performed more than 60,000 heart surgeries in his career that lasted 70 years. His patients had included the Duke of Windsor, the Shah of Iran, King Hussein of Jordan, Turkish President Turgut Ozal, Nicaraguan leader Violetta Chamorro, President Kennedy, President Johnson, and President Nixon. He was a consultant when Russian President Boris Yeltsin had surgery.

He served as the chairman of the President’s Commission on Heart Disease, Cancer, and Stroke during President Johnson’s administration. He had helped to establish the National Library of Medicine and was the author of more than 1,000 medical reports, papers, chapters, and books on surgery, medicine, and similar topics.

In 1953, he performed the first Dacron graft to be able to replace part of occluded arteries. In the 1960s he started coronary artery bypasses. In 1966, he was the first person to successfully use a partial artificial heart. In the 1990s, he helped to create the Michael E. DeBakey Heart Instititute at Hays Medical Center.

Common Causes of Strokes

Most strokes happen when clot blocks blood flow to the brain. Strokes can also happen when a blood vessel bursts in the brain. High blood pressure encourages strokes because it can cause a buildup of arterial plaque, which can cause blood clots.

Birth control pills and hormone therapy increases the risk of having a stroke. Hormone therapy for menopause symptoms has less estrogen than birth control pills but still increases the risk of stroke a little bit.

Sleep apnea is a condition that interrupts the breathing process while a person is asleep. It raises blood pressure and the risk of having a stroke.

Other things that increase the risk of stroke include blood clotting disorders and having migraines with auras. Auras are visual changes that happen before having a migraine.

The risk of having a stroke can be cut in half just by lowering high blood pressure and high cholesterol. If a female has high cholesterol, hypertension, obesity, or diabetes, then she should be very cautions when taking birth control pills so that she can lower the risk of having a stroke.

Ways to Prevent Memory Loss

Memory loss usually starts at 16 years old and it is a common problem for people by the age of 40. There are things that can be done to prevent it.

Regular exercise can help to prevent the arterial aging that plays a part in memory loss. Exercise uses concentration and coordination, which are two things that require the use of brain neurons and keep them active.

There are some nutrients that fight memory loss. Omega-3 fatty acids help to keep the arteries clear and improve the process of message-sending brain neurotransmitters. They are found in fatty fish, such as salmon and mahimahi. It is recommended to eat 13 ounces of fish each week or take two grams of fish oil supplements, DHA, each day.
