My esr level is 2. i am concerned about congestive heart failure. i have had an ekg and chest x ray, both okay. is heart failure still a possibility?

Anxiety disorder: This question does not provide sufficient info to exclude heart disease, nor does it provide even a remote suggestion that a 27 year old woman would develop CHF without some severe underlying clinical problem. You are overthinking this and need to find out why the level of concern. After discussing with you doctor you might consider seeing a clinical psychologist or psychiatrist. Good luck.

ESR is normal: Although people talk about congestive heart failure being associated with a low ESR (sed rate), there typically is not really a sed rate that is abnormally low. A normal ESR for a young woman, in most labs, is 0-20 mm/hr. The finding of an ESR of 2 should not warrant a heart failure evaluation. If you have no symptoms of heart failure, don't worry.
