Question

a 56 year old woman has elevated ast, ldh and cpk. she seems anxious and pale. what exams would you perform and what is your working diagnosis?

Explanation:

AST (aspartate aminotransferase), LDH (lactate dehydrogenase), and CPK (creatine phosphokinase) are enzymes. Elevated levels can be associated with heart - related issues. An electrocardiogram (ECG) can show the heart's electrical activity. Troponin levels (a biomarker for heart muscle damage) should be checked. Given the symptoms (anxiety, pallor) and enzyme elevations, a working diagnosis could be myocardial infarction (heart attack).

Answer:

Exams: Electrocardiogram (ECG), Troponin levels. Working diagnosis: Myocardial infarction.
