Blood work was normal, ekg came back they said there was a little abnormality on it. w/ blood coming back normal could i still have heart issues?

Yes: There are many trivial abnormalities of the ekg that are of no consequence, and others that are seriously concerning. Usually these have nothing to do with cholesterol or lifestyle or routine labs. Your physician knows how to deal with this. It's also good to have a baseline ekg in case your cardiac health changes.

Insufficient info: Normal ekg and blood tests do not rule out coronary artery or heart disease. You should discuss your risk factors with your doctor to see if preventive actions/medications are warranted. See the site below for more info http://www.Cdc.Gov/heartdisease/about.Htm.

Yes: Asymptomatic CAD or structural heart disease may be present. Other tests such coronary calcium screening & echocardiogram would screen for those.
