Yes except heart: B12 deficiency can cause a variety of neurological symptoms including "derealization"; it can adversely affect brain function but that damage should be reversible. It can cause high homocysteine which increases risk of cardiovascular disease ; anemia puts stress on hearts, but it should not directly cause heart problems in someone your age.
