Summary
3 papers analyzed
These studies suggest that high cholesterol can present with symptoms such as increased severity of hyperlipidaemia, physical signs like tendon xanthomas or corneal arcus, and an increased risk of coronary artery disease, especially in those with familial hypercholesterolemia.

High Cholesterol: Signs and Symptoms
High cholesterol, particularly familial hypercholesterolemia (FH), is a significant risk factor for cardiovascular diseases. Understanding the signs and symptoms associated with high cholesterol can aid in early diagnosis and management.
Physical Signs of High Cholesterol
Xanthomas and Corneal Arcus
One of the most notable physical signs of high cholesterol is the presence of xanthomas, which are fatty deposits that can appear on the skin, particularly around the eyes, elbows, and knees. Corneal arcus, a gray or white arc visible around the cornea of the eye, is another indicator. These signs are particularly prevalent in individuals with familial hypercholesterolemia (FH) and are associated with higher levels of low-density lipoprotein (LDL) cholesterol and genetic mutations in the LDL receptor (LDLR), apolipoprotein B (APOB), and proprotein convertase subtilisin/kexin type 9 (PCSK9) genes .
Tendon Xanthomas
Tendon xanthomas, which are cholesterol deposits in the tendons, are also common in patients with FH. These physical signs are linked to higher LDL cholesterol levels and increased risk of coronary artery disease (CAD). The presence of tendon xanthomas can indicate a more severe form of hypercholesterolemia and a higher likelihood of cardiovascular events.
Clinical Manifestations
Coronary Artery Disease (CAD)
High cholesterol levels, particularly elevated LDL cholesterol, are strongly associated with the development of coronary artery disease (CAD). Studies have shown that individuals with clinical signs of FH, such as xanthomas and a family history of hypercholesterolemia, have a significantly higher risk of developing CAD compared to those without these signs. The risk is further amplified in individuals who also have genetic mutations associated with FH.
Cardiovascular Events
Patients with physical signs of high cholesterol, such as tendon xanthomas and corneal arcus, are at a greater risk of cardiovascular events. These signs are associated with higher levels of inflammatory markers like high-sensitivity C-reactive protein (hsCRP) and higher coronary artery calcium scores, indicating more severe coronary artery disease. Over time, these patients are more likely to experience adverse cardiovascular events, underscoring the importance of early detection and management.
Conclusion
Recognizing the physical signs and clinical manifestations of high cholesterol is crucial for early diagnosis and intervention. Xanthomas, corneal arcus, and tendon xanthomas are key indicators of elevated cholesterol levels and familial hypercholesterolemia. These signs are associated with a higher risk of coronary artery disease and cardiovascular events, highlighting the need for vigilant monitoring and proactive treatment in affected individuals.
