Heart Condition

High Cholesterol (Hyperlipidaemia and Dyslipidaemia)

High cholesterol, or hyperlipidaemia, refers to too much “bad” LDL cholesterol. Dyslipidaemia, is an imbalance of fats in the blood, typically too much “bad” LDL and triglyceride cholesterol and not enough “good” HDL cholesterol. Over time, excess bad cholesterol contributes to the build-up of plaque in the arteries, increasing the risk of heart attack and stroke. It does not cause symptoms till late in its course when arteries are significantly narrowed.

High Cholesterol (Hyperlipidaemia and Dyslipidaemia)

01Symptoms

Common signs and symptoms associated with High Cholesterol include:

Usually no symptoms
Detected through a simple blood (lipid) test
In severe inherited forms, cholesterol deposits may appear on the skin or tendons
The first sign can be a heart attack or stroke if left unaddressed

02Causes & Risk Factors

Family history/genetic factor
Less frequent but severe form called familial hypercholesterolaemia
An unhealthy diet high in saturated and trans fats
Being overweight and inactive
Smoking
Diabetes
Increasing age
Excessive alcohol may cause hypertriglyceridaemia

03When To See A Cardiologist

Have your cholesterol checked as part of a routine heart screening, particularly if you are over 40, have a family history, or have other heart risk factors. A cardiologist can interpret your results in the context of your overall cardiovascular risk.

04Treatment Approaches At CCI

Treatment begins with diet and lifestyle change. Where the risk warrants it, cholesterol-lowering medication such as statins is safe and highly effective at reducing heart attack and stroke risk. Dr Lee has given lectures to medical peers on the role of statins and modern lipid management. Some patients may need additional medicine to lower cholesterol, such as ezetimibe and PCSK-9 Inhibitor. Every patient's treatment is individualised.
