第 31 題
有關慢性穩定性心絞痛病人的治療原則，下列何者錯誤？
- A β-blockers 有較多的副作用，calcium-channel blockers 較適合做為第一線用藥
- B 所有病人都應隨身攜帶 nitroglycerin SL tablets
- C 所有病人都應規律服用 antiplatelet agent
- D long-acting nitrates 不應做為單獨治療（monotherapy）
思路引導 VIP
同學，請回想在慢性穩定性心絞痛（Chronic Stable Angina）的臨床治療指引中，針對降低心肌耗氧量並改善病人預後，$\beta$ 受體阻斷劑（$\beta$-blockers）與鈣離子通道阻斷劑（Calcium-channel blockers）哪一者在藥理學上通常被列為『首選』的第一線（First-line）治療藥物？這兩類藥物在臨床應用的優先順位是否有別？

Barely Adequate: A Glimmer of Understanding
- Acknowledge the Anomaly: Hmph. So, you actually managed to correctly identify the glaring error in option (A). A surprising display, I must admit. It suggests you've, perhaps by accident, absorbed the Ischemic Heart Disease (IHD) treatment guidelines. Don't let it go to your head; it's merely foundational.
- Reinforce the Obvious: Let's be unequivocally clear: in chronic stable angina, the undisputed first-line therapy is $\beta$-blockers. They are designed to methodically reduce heart rate and myocardial oxygen demand. Calcium-channel blockers (CCB) are not the primary choice; they're a contingency, reserved for intolerance to $\beta$-blockers or as an adjunct. It's a basic distinction, yet consistently muddled by lesser minds. Furthermore:

慢性穩定性心絞痛治療
💡 穩定性心絞痛治療首選 β-blockers 以緩解症狀並改善預後。
| 比較維度 | β-blockers (BB) | VS | Calcium Channel Blockers (CCB) |
|---|---|---|---|
| 治療地位 | 穩定型心絞痛第一線首選 | — | 二線藥物或 BB 禁忌時使用 |
| 主要機轉 | 降低心率與收縮力，減少耗氧 | — | 擴張冠狀動脈，降低體血管阻力 |
| 改善預後 | 具心臟保護作用，可降低死亡率 | — | 主要是緩解症狀，預後效益較低 |
| 特殊禁忌 | 氣喘、嚴重緩慢心律不整 | — | 收縮性心衰竭（non-DHP） |
💬BB 是穩定型心絞痛的首選，CCB 通常作為輔助或替代藥物。
