Cholesterol Level Calculator Description

Understanding Lipids and Cardiovascular Risk

Cholesterol and triglycerides are lipids essential for cell structure and metabolism. However, when imbalanced, they contribute to cardiovascular disease.

Key Lipid Components

• Total Cholesterol (TC): Sum of HDL, LDL, and 20% of triglycerides.
• HDL (High-Density Lipoprotein): "Good" cholesterol—helps remove excess cholesterol.
• LDL (Low-Density Lipoprotein): "Bad" cholesterol—builds up in arteries.
• Triglycerides: Type of fat used for energy storage.

Primary Formulas Used

Friedewald Formula (valid when triglycerides < 400 mg/dL):

LDL = Total Cholesterol - HDL - (Triglycerides / 5)

Cholesterol Ratio:

Cholesterol Ratio = Total Cholesterol / HDL

• Ideal Ratio: Below 3.5
• High Risk: Above 5.0

Mini Case Studies

Case Study 1: High Triglycerides

• Values: Total = 210 mg/dL, HDL = 45 mg/dL, Triglycerides = 480 mg/dL
• Result: Friedewald formula invalid due to triglycerides > 400 mg/dL
• Action: Use direct LDL measurement or alternate formula

Case Study 2: Low HDL, Normal TC

• Values: Total = 190 mg/dL, HDL = 30 mg/dL, Triglycerides = 100 mg/dL
• LDL: 190 - 30 - (100 / 5) = 140 mg/dL
• Ratio: 190 / 30 = 6.33 (high risk despite normal TC)

Important Edge Cases

• Non-Fasting Samples: May raise triglycerides and distort LDL estimate
• Triglycerides > 1000 mg/dL: Severe interference with lipid calculations
• Inherited Disorders: Dysbetalipoproteinemia invalidates Friedewald assumptions
• LDL Pattern B: Small dense LDL particles are more atherogenic despite similar quantity
• Hormonal Effects: Conditions like hyperthyroidism can lower LDL falsely
