      "description": "用 Friedewald 公式间接计算 LDL-C。mg/dL：LDL-C = 总胆固醇 − HDL-C − 甘油三酯/5；mmol/L：LDL-C = TC − HDL-C − TG/2.2。该公式假设 TG 与 VLDL-C 比值恒为 5:1，当 TG ≥ 400 mg/dL（4.5 mmol/L）时不再可靠——会系统性低估 LDL-C，应改用直接法或 Martin/Hopkins（2013）、Sampson-NIH（2020）公式；非空腹餐后（乳糜微粒）、III 型异常 β 脂蛋白血症及 LDL-C < 70 mg/dL 时亦不准确。治疗阈值（ACC/AHA 2018）：< 70 mg/dL（1.8 mmol/L）极高危二级预防；< 100 mg/dL（2.6 mmol/L）中危/糖尿病一级预防；100–129 边界；130–159 边界升高；160–189 升高；≥ 190 mg/dL（4.9 mmol/L）提示家族性高胆固醇血症。来源 Friedewald 1972、Martin 2013、Sampson 2020、ACC/AHA 2018。不构成医疗建议。",
