Study Notes
Dyslipidaemia
- Dyslipidaemia is an elevated level of lipids in the blood, including cholesterol, LDL, and triglycerides.
- It is often asymptomatic until it develops into other diseases.
Causes of Hypercholesterolemia
- Familial hypercholesterolemia (primary hypercholesterolemia): a genetic disorder characterized by an increase in liver production of cholesterol.
- Secondary hypercholesterolemia: associated with other health problems such as:
- Obesity
- Sedentary lifestyle
- Diabetes mellitus
- Hypothyroidism
- Nephrotic syndrome (due to protein loss)
Effects of Dyslipidaemia
- Linked to multiple disease conditions:
- Atherosclerosis
- Peripheral vascular disease
- Coronary artery disease
- Stroke
- Symptoms include:
- Chest pain in case of coronary artery disease
Lifestyle Modifications
- Consumption of low-cholesterol, low-fat foods
- Routine exercise
- Weight reduction
- Tobacco and alcohol cessation (if applicable)
Pharmacological Treatment
- Statins: HMG-CoA reductase inhibitors, inhibiting hepatic synthesis and increasing catabolism
- Fibrates: used mainly to decrease elevated triglycerides levels
- Omega 3 fatty acids
Laboratory Assessment
- Dyslipidaemia can be laboratory assessed by measuring fasting lipid profile:
- LDL
- HDL
- Cholesterol
- Triglycerides
