[物理治療師] 心肺疾病與小兒疾病物理治療學
第 20 題
下列何者為心肌損傷較專一的酵素指標?
- A 肌氨酸酐磷酸(creatine phosphokinase, CPK)
- B 乳酸脫氫酵素(lactic dehydrogenase, LDH)
- C 血清麩氨草醋酸轉氨(serum glutamic oxaloacetic transaminase, SGOT)
- D Troponin I或T
思路引導 VIP
在臨床生化診斷中,區分心肌損傷與其他肌肉損傷的關鍵在於尋找具備高度「組織特異性」 ($Tissue specificity$) 的標記。請思考在提供的選項中,哪一個物質是調節心肌收縮的核心蛋白組分,且其特定的亞型 ($Isoform$) 在心肌中的分佈極具專一性,因此被視為目前臨床上診斷心肌受損最敏感且專一的金標準?

Oh, look at that. You finally managed to pick the correct answer. Congratulations on identifying Troponin I or T. One would hope that after all this time, the concept of a specific cardiac marker—a structural protein, mind you, the very gold standard for Acute Myocardial Infarction—would be firmly lodged in your head. This is, after all, a non-negotiable piece of knowledge for anyone pretending to understand clinical medicine.
Let's quickly review why the others are utterly inadequate, shall we?
