Case Study 1
John, 45, has a total cholesterol of 220 and an HDL of 50. His estimated LDL is 140.
Case Study 2
Jane, 55, has a total cholesterol of 200 and an HDL of 60. Her estimated LDL is 110.
Case Study 3
Mike, 35, has a total cholesterol of 240 and an HDL of 40. His estimated LDL is 180.
| LDL Level (mg/dL) | Risk Category |
|---|---|
| Less than 100 | Optimal |
| 100-129 | Near optimal |
| 130-159 | Borderline high |
| 160-189 | High |
| 190 or above | Very high |
| Risk Category | LDL Lowering Goal (mg/dL) |
|---|---|
| High risk | Less than 70 |
| Moderate risk | Less than 100 |
| Low risk | Less than 130 |
- Regular exercise and a heart-healthy diet can lower LDL levels.
