My father is in hospital with chest pain off and on along with numbness in both hands. his troponin level is 2.55. no answers... any thoughts?

Ischemic Heart Dis: Chest pain with elevated troponin needs an urgent evaluation by a cardiologist. Since your father is already in the hospital, I presume he has already been evaluated by a cardiologist or if there is no cardiologist, he has been sent immediately to a hospital that has the capacity and personnel to evaluate and treat. He may be having a serious heart attack.

Ischemic heart Dz: A troponin level > 0.05 ng/mL indicates some sort of heart damage. I assume by "2.55" u mean 2.55 ng/mL, which is definitely abnormal. When cholesterol builds up but does not block an artery to the heart, it is called ischemic heart disease (IHD) & can lead to intermittent pain & numbness in the (left) hand. He shd be checked out by a Cardiologist b4 an artery becomes blocked off, ie heart attack.
