Special Imaging Study Shows Failing Hearts Are 'Energy Starved'

Using magnetic resonance spectroscopy (MRS) for the first time to examine energy production biochemistry in a beating human heart, Johns Hopkins researchers have found substantial energy deficits in failing hearts. The findings, published in the January 18 issue of the Proceedings of the National Academy of Sciences, confirm what many scientists have conjectured for years about heart fail...

Bone marrow stem cells may heal hearts even years after heart attacks

Left ventricular function and exercise capacity increased, while the area of heart muscle damage shrank, in 18 patients given infusions of their own bone marrow stem cells up to eight years after a heart attack, according to a new study in the Nov. 1, 2005, issue of the Journal of the American College of Cardiology. "This new therapy is able to treat until now irreversible heart complaints...

Mice with glowing hearts shed light on how hearts develop

Cornell researchers have genetically engineered mice whose hearts glow with a green light every time they beat. The development gives researchers insights into how hearts develop in living mouse embryos and could improve our understanding of irregular heartbeats, known as arrhythmias, as well as open doors to observing cellular processes to better understand basic physiology and disease. T...

Free-radical busting antioxidants might not promote healthy hearts

Antioxidants, such as beta-carotene and Vitamin E, have been touted for their ability to protect against heart disease. This protective effect is attributed to their ability to prevent the oxidation of bad cholesterol by free radicals—a process thought to contribute to the build-up of disease-causing fatty deposits on artery walls. But a new study, published online on April 10 in The Journal of E...

UT Southwestern researchers find gene mutation that leads to 'broken hearts'

Researchers at UT Southwestern Medical Center have identified a group of fruit fly gene mutations responsible for "broken hearts" in the embryonic stages of development, a discovery that could help identify genes that cause human heart defects. "We engineered a fruit fly so that the heart would glow in the dark and found a new type of malformation, completely unexpectedly," said Dr. Eric...

Vitamin E supports Female Hearts

According to a new study in the American Journal of Clinical Nutrition it was observed that vitamin E may play an important role in preventing the build up of plaque in the arteries that can lead to cardiovascular disease.// Research has shown antioxidant vitamins can protect against the formation of plaque in the arteries. However, most studies have concentrated on people who were alr...

Reconstituted Blood Better For Young Hearts

Young children who undergo heart surgery fare better if they receive reconstituted blood rather than fresh whole blood say researchers.// Investigators say that children who received reconstituted blood -- which is made from stored red blood cells and plasma -- tended to accumulate less fluid, which leads to lower rates of inflammation. For the study, researchers compared resul...

A Call To Open Up The Channel Of Goodwill To Rescue The Dying Hearts

The plight of poor children with congenital heart diseases (CHD) here moved NRIs into donating// $200,000 at a fund-raiser dinner held in the US by a non-profit organization. About 40-50 NRIs have offered to sponsor a child each. Some of them are keen to sponsor a child or two every year According to medical reports, every year, nearly 200,000 children are born in India with CHD. Only...

Surgeons in India to Mend ‘Pakistani Hearts’ by treating 70 Childrn

Mumbai, Sep 18 India and Pakistan maybe daggers drawn on many issues, however one issue that is likely// to win many friends include the treatment in India of 70 poor Pakistani children later this month for heart treatment. This one gesture is likely to pave path towards many more similar gestures and result in a harmony between the two countries that politician on both sides of the b...

Novel Biological Pacemaker Under Construction for Weak Hearts

Johns Hopkins scientists have developed a natural or rather biological pacemaker by fusing connective tissue cells of guinea pigs with heart muscle cells. The newly developed pacemaker can fire on it’s own and regulate the rhythm // of the heart in a more physiological way. Two sets of tiny electroactive 'pacing cells' (SA node) give rise to the heart’s normal rhythm by stimulating oth...
