NEW YORK (Reuters Health) - Older patients with heart failure had more memory problems when their heart ailments were advanced, in a new study of adults being evaluated for transplants. But that wasnt the case in young and middle-aged adults with a type of heart failure marked by a lower-than-normal amount of blood being pumped by the left ventricle. As you get older, theres more atrophy in the brain, said study author Joanne Festa, from St. Lukes-Roosevelt Hospital in New York. It could be that particularly in heart failure the brain atrophies at a quicker rate. The findings tell cardiologists they need to be aware that their patients might be at higher risk of memory problems - problems that could come into play in their heart treatment, Festa added.
