VIENNA, Austria-Global warming may be forcing polar bears southward and melting glaciers, but it could also have an impact on your heart.Doctors warn that the warmer weather expected with climate change might also produce more heart problems."If it really is a few degrees warmer in the next 50 years, we could definitely have more cardiovascular disease," said Dr. Karin Schenck-Gustafsson, of the department of cardiology at Sweden's Karolinska Institute.On the sidelines of the European Society of Cardiology's annual meeting in Vienna this week, some experts said that the issue deserved more attention. It's well-known that people have more heart problems when it's hot.During the European heat wave in 2003, there were an estimated 35,000 deaths above expected levels in the first two weeks of August. In France alone, nearly 15,000 extra people died when temperatures soared. Experts say that much of that was due to heart problems in the elderly worsened by the extreme heat.The hardening of the heart's arteries is like rust developing on a car. "Rust develops much more quickly at warm temperatures, and so does atherosclerosis," said Dr. Gordon Tomaselli, chief of cardiology at Johns Hopkins University and program chair at the American Heart Association.In higher temperatures, we sweat to get rid of heat. During that process, blood is sent to the skin where temperatures are cooler, which opens up the blood vessels. In turn, the heart rate rises and blood pressure drops. That combination can be dangerous for older people and those with weakened cardiovascular systems.Extreme events like the recent devastating fires in Greece may complicate the problem. The increasing number of forest fires that have swept through Southeast Asia in the last decade have also brought a spike in heart disease, experts say.To read more go to:
