護理師為 60 歲個案進行心血管健康篩檢。下列哪項發現被視為冠狀動脈疾病的主要危險因子？
A nurse is screening a 60-year-old client for cardiovascular health. Which of the following findings is considered a primary risk factor for coronary artery disease?
- AHigh-density lipoprotein (HDL) level of 70 mg/dL高密度脂蛋白 (HDL) 濃度為 70 mg/dL
- BFasting blood glucose of 95 mg/dL空腹血糖為 95 mg/dL
- CTriglyceride level of 120 mg/dL三酸甘油酯濃度為 120 mg/dL
- DLow-density lipoprotein (LDL) level of 160 mg/dL✓ 正解低密度脂蛋白 (LDL) 濃度為 160 mg/dL
— Explanation · 中文詳解 —
高 LDL 是冠狀動脈疾病（CAD）的核心指標。160 mg/dL 屬於高風險範圍，容易導致血管壁斑塊形成。HDL 70 mg/dL 為保護性高值；三酸甘油脂 120 mg/dL 在正常範圍；空腹血糖 95 mg/dL 屬於正常，皆非主要危險因子。控制 LDL 是心血管預防的基石。
An LDL level of 160 mg/dL is a primary risk factor for coronary artery disease as it contributes significantly to atherosclerosis. In contrast, an HDL level of 70 mg/dL is protective, and both fasting glucose of 95 mg/dL and triglycerides of 120 mg/dL fall within normal ranges. Therefore, elevated LDL is the key indicator requiring intervention.
