- An HDL level of 60 mg/dL (1.5 mmol/L) or higher protects against heart disease.
- HDL cholesterol levels of 40 mg/dL (1.0 mmol/L) or lower increase your risk of developing heart disease, especially if you also have high total cholesterol levels.
- Very high cholesterol and triglyceride levels may be caused by an inherited form of high cholesterol (hypercholesterolemia or hyperlipidemia).
- If you have a very high risk of having a heart attack, your doctor may want your LDL level to be less than 70 mg/dL. You have a very high risk if you smoke and have coronary artery disease, or if you have coronary artery disease and diabetes, acute coronary syndrome, or metabolic syndrome.
Many conditions can affect cholesterol and triglyceride levels. Your health professional will talk with you about any abnormal results that may be related to your other health problems.
