Nitric oxide may help prevent kidney issues after heart surgery

Nitric oxide may help prevent kidney issues after heart surgery

Health
June 20 (UPI) -- A randomized, controlled trial in China recently found that patients who inhaled nitric oxide during and for 24 hours after heart surgery saw a decreased risk of developing acute and chronic kidney problems. The study, published in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine, is the first to show a drug could reduce kidney injury resulting from heart surgery, the researchers say. Previous studies have shown that prolonged cardiopulmonary bypass can disrupt circulating red blood cells and the release of hemoglobin, which can cause acute kidney injury that leads to kidney failure and the need for long-term hemodialysis. While several drugs have been tested to prevent kidney problems after surgery, this is the first one that ac...

Caffeine could protect the heart by helping it make energy, mouse study finds

Coffee can do more than just keep people awake for the day -- studies have shown that moderate amounts of caffeine, like what's in coffee, can actually protect the heart. A new study looked at possible reasons for those beneficial effects, by studying the genes of mice. "We wanted to do this study to show people coffee is not as bad for your heart as people thought for a long time," co-author Dr. Judith Haendeler, medical faculty at the HHU Duesseldorf and IUF-Leibniz Research Institute for Environmental Medicine, told ABC News. But why could coffee-like caffeine levels be helpful for the heart? Building on their previous research that showed that caffeine could help with the repair of cells lining blood vessels, called endothelial cells, researchers at the Heinrich-Heine-University a...
Loneliness does more than pull on your heart strings — it may hurt your heart

Silent, uncomfortable, forlorn, withdrawn -- these are all feelings likely felt by the lonely. Research shows that these feelings don’t just cause emotional stress, they are part of a real association between social isolation and negative health outcomes. For the first time, studies are looking at heart failure in lonely people. Over 6 million people live with heart failure in the United States, with over 960,000 new cases diagnosed each year. By 2030, there may be more than 8 million cases of heart failure. “One in five Americans over the age of 40 are affected by heart failure,” Dr. Clyde Yancy, American Heart Association (AHA) spokesperson and chief of the cardiology division at Northwestern University's Feinberg School of Medicine, told ABC News. It’s a con...

April 25 (UPI) -- Researchers have figured out why exercise is good for the heart, at least in mice: It helps the organ generate more new heart muscle cells.Exercise can even deliver the benefit after a heart attack, according to researchers from the Harvard Department of Stem Cell and Regenerative Biology, Massachusetts General Hospital, Harvard Medical School and the Harvard Stem Cell Institute. The researchers, who published their findings Wednesday in the journal Nature Communications, noted that public health, physical education and the rehabilitation of cardiac patients can help prevent heart failure."We wanted to know whether there is a natural way to enhance the regenerative capacity of heart muscle cells," Dr. Ana Vujic, a researcher at Harvard, said in a press release. "So we dec...
