Lipid Profile | Cholesterol, HDL(good), LDL(bad), & triglycerides elevation indicates risk for MI |
LDH | found throughout body with a certain % that assesses MI usually peaks w/in 24-48 hrs of MT. If increased Infarct present. Used to monitor resolution of MI |
Troponin | Indicates injury to heart muscle (if Troponin is, then injury to heart muscle occurred) Typically peaks w/in 24 hrs. Monitored for reduction in value to determine if MI is resolving. *Creatine may also be elevated with MI |
CK or CPK | Indicates injury to heart muscle (aka CKMB) |
Potassium | Can affect heart function (widen QRS or pointed T-waves if high; inverted T-waves if low) Electrolyte imbalance, dehydration, taking diuretics. *may drop after insulin. *Monitors kidney function |
BNP | Diagnose presence and severity of heart failure . *chronic CHF will have a BNP>500 |
PT/PTT | Evaluate the ability of blood to clot properly, used to assess both bleeding and clotting tendencies. *monitor status of blood thinning medicines |
INR | Measure pf blood's clotting ability (normal=1.0; normal on blood thinners= 2.0-3.0) |
D-Dimer | Tests hypercoagulability (a tendency to clot inappropriately) + (pos) means that there is an abnormally high level of fibrin degradation products in the body (due to a clot breaking down) **if positive could indicate a PE (clot in lungs) |
