Silent But Deadly

Finding it tougher to climb the stairs at work, complete your aerobics class, or finish your regular run on the treadmill? You might want to speak with your doctor about possible 'silent cardiac dysfunction,' say heart experts. The ability to perform aerobic exercise is an indicator of heart health. And although it is natural for exercise tolerance to slowly decrease due to aging, a sudden drop-off could be a very early, 'silent' sign of cardiovascular disease, even when no other symptoms are present, researchers report in the journal AIDS. Because some antiretroviral drugs are linked with higher cardiac risks, HIVers should be particularly mindful of any changes in exercise's effects on their bodies.
