What characterizes dyslipidaemia?

What characterizes dyslipidaemia?

• A. Abnormal lipid profile with elevated LDL-C, triglycerides, and/or low HDL-C, contributing to atherosclerosis risk.
• B. Normal lipid profile with controlled LDL-C and HDL-C.
• C. Low triglyceride levels with high HDL-C.
• D. Elevated HDL-C only with no effect on atherosclerosis.

Answer: (A)

Dyslipidaemia is defined by an abnormal lipid profile. In practice, this means levels that are off the normal range, most often with elevated LDL-C and/or elevated triglycerides and/or low HDL-C. These changes promote atherosclerosis because LDL cholesterol deposits cholesterol into arterial walls, high triglyceride–rich particles contribute to plaque formation, and low HDL-C reduces the removal of cholesterol from vessels. So, describing an abnormal lipid profile with these patterns and linking it to increased atherosclerosis risk best captures what dyslipidaemia is. The other options describe normal or favorable lipid states that don’t characterize dyslipidaemia.
