Understanding Cholesterol Levels

Cholesterol is measured in milligrams per deciliter (mg/dL). Total cholesterol should be below 200 mg/dL, HDL (good cholesterol) above 40-60 mg/dL, LDL (bad cholesterol) below 100 mg/dL, and triglycerides below 150 mg/dL.

About Cholesterol Ratios

The cholesterol ratio (total cholesterol ÷ HDL) is a better predictor of heart disease risk than total cholesterol alone. A ratio below 3.5:1 is considered ideal, while a ratio above 5:1 indicates increased risk.

Heart Disease Risk Analysis

Cholesterol Ratio Formula

Cholesterol Ratio = Total Cholesterol ÷ HDL Cholesterol

The cholesterol ratio is calculated by dividing your total cholesterol level by your HDL (good) cholesterol level. Lower ratios indicate better cardiovascular health. A ratio of 5:1 or higher indicates increased risk of heart disease.

LDL/HDL Ratio = LDL Cholesterol ÷ HDL Cholesterol

This additional ratio provides further insight into heart disease risk. An optimal LDL/HDL ratio is below 2:1, while a ratio above 4:1 indicates high risk.
