The higher the ratio, the higher the risk. Most healthcare providers want the ratio to be below 5:1. A ratio below 3.5:1 is considered very good.
Cholesterol Ratio Ranges
Between 3.5 and 5 to 1: This ratio is considered normal. A cholesterol ratio within the normal range means that your cholesterol levels put you at lower risk for heart disease. Above 5 to 1: This results is considered high, putting you at elevated risk.
For predicting your risk of heart disease, many doctors now believe that determining your non-HDL cholesterol level may be more useful than calculating your cholesterol ratio.
What cholesterol levels are considered normal in Australia? The recommended blood cholesterol targets rely on a number of factors that are based on your personal risk. For the general healthy population, a total cholesterol of less than 5.5 mmol/L, LDL less than 2.0mmol/L and HDL of greater than 1.0 mmol/L is advised.
LDL cholesterol.
The LDL measurement is usually considered the most important for assessing risk and deciding on treatment.
In general: The higher the ratio, the higher the risk. Most healthcare providers want the ratio to be below 5:1. A ratio below 3.5:1 is considered very good.
LDL -cholesterol levels greater than 3.5 mmol/L are considered elevated for some people at low cardiovascular risk and most individuals at intermediate risk and may need behavior modifications and/or pharmacological treatment Note 5 (see About cholesterol).
Your ideal total cholesterol level should be around 150. Your LDL levels should be around 100 mg/dL. This range helps put you at a low risk of heart disease. Less than 120 mg/dL total cholesterol or an LDL level less than 50 mg/dL is very low.
It is recommended that healthy adults should have a total cholesterol level below 5 mmol/L. The total cholesterol level includes LDL (bad cholesterol) and HDL (good cholesterol). The risk of coronary heart disease is particularly high if you have a high level of LDL cholesterol and a low level of HDL cholesterol.
Low-density lipoprotein (LDL) is the "bad cholesterol" in terms of its potential for harming the heart and brain. It is a major contributor to arterial plaque development. Levels of LDL cholesterol higher than 130 milligrams per deciliter (mg/dL) are linked to an increased risk for ischemic stroke.
Cholesterol Ratio
An optimal ratio is less than 3.5 to 1. A higher ratio means you're more at risk for heart disease.
Healthy seniors should keep their total cholesterol below 200 and their LDL cholesterol around 100. If your elderly loved one's LDL cholesterol level is above 160, he or she must start making sweeping lifestyle changes.
You develop symptoms of heart disease, stroke, or atherosclerosis in other blood vessels, such as left-sided chest pain, pressure, or fullness; dizziness; unsteady gait; slurred speech; or pain in the lower legs. Any of these conditions may be linked to high cholesterol, and each requires medical help right away.
Research shows that high LDL in early adulthood is linked with a 64% increase in heart disease risk later on, compared to a healthy LDL level. High systolic and diastolic blood pressure are linked with 37% and 21% increased risks, respectively, for heart failure.
High cholesterol is linked to blood clots and a higher risk of stroke. Research shows lowering cholesterol can lower the risk of another stroke by about 20%. National Stroke Guidelines strongly recommend taking medication to lower LDL cholesterol to under 1.8 mmol/L (70 mg/dL).
If your LDL-C reading is outside healthy levels, speak to your GP - if it's above 4.9 mmol/L you could have familial hypercholesterolaemia (FH), a form of inherited high cholesterol that needs treatment and lifestyle changes.
Your LDL cholesterol number is: Optimal if it is less than 2.6 mmol/L (100 mg/dL) Near optimal/above optimal if it is 2.6 3.3 mmol/L (100-129 mg/dL) Borderline high if it is 3.4 4.1 mmol/L (130-159 mg/dL)
It's best to keep your total cholesterol level below 200. Women of any age should have an HDL level of 40 or higher. If you already have heart disease or diabetes, or your doctor estimates that your 10-year risk of heart disease is 20 percent or higher, try to keep your LDL level below 100.
Healthy cholesterol levels for seniors are below 200 mg/dl (total cholesterol), including an HDL (good) cholesterol level of more than 40 mg/dl for men, 50mg/dl for women, and an LDL (bad) cholesterol level of less than 100 mg/dl.
