How is LDL-P measured?
LDL-P measured by nuclear magnetic resonance (NMR) spectroscopy, calculated LDL-C, and carotid intima-media thickness (IMT) were assessed at baseline in the Multi-Ethnic Study of Atherosclerosis (MESA), a community-based cohort of 6814 persons free of clinical CVD at entry and followed for CVD events (n=319 during 5.5- ...
What is the formula to calculate LDL?
The traditional Friedewald equation estimates LDL cholesterol this way: total cholesterol minus HDL cholesterol minus triglycerides divided by five.
What is a normal LDL-P level?
LDL-P is measured by a nuclear magnetic resonance (NMR) lipid profile test. A value of less than 1,000 is considered ideal. Above 2,000 is considered very high.
What is the difference between LDL and LDL-P?
LDL-P is the number of LDL particles, while LDL-C is the amount of cholesterol carried by these LDL particles. Similarly, apoB is the number of apoB particles (most of which are LDL particles), while NHDL-C is the amount of cholesterol carried by these apoB particles.
How is HDL and LDL calculated?
Your LDL is computed by plugging the measurements for total cholesterol, HDL, and triglycerides into a: LDL = Total cholesterol – HDL – (Triglycerides ÷ 5). LDL can also be measured directly in a non-fasting blood sample.
Is LDL calculated or measured?
Usually, your LDL-C level is calculated using the measured values of the components of a standard lipid panel: total cholesterol, high-density lipoprotein cholesterol (HDL-C), and triglycerides. Using a mathematical equation, the amount of LDL-C can be determined from the three measured values.
What is a good number for small LDL-P?
0 - 527 nmol/LOptimal Result: 0 - 527 nmol/L. Your Small LDL-P number is a measure of the number of small LDL particles in your blood. These particles are associated with an increased risk of heart disease; more of these small particles lead to greater risk.
Why is my LDL-P so high?
Genetics. The final cause of elevated LDL-P is genetics. Familial hypercholesterolemia, or FH, involves a mutation of a gene that codes for the LDL receptor or the gene that codes for apolipoprotein B (ApoB).
Do statins reduce LDL-P?
Statins Do Not Decrease Small, Dense Low-Density Lipoprotein.
Can you have high LDL C and low LDL-P?
If LDL-C is low and LDL-P is high, there is discordance. If both are low or both high, there is no discordance. Studies have indicated that if there is discordance between LDL-C and LDL-P, cardiovascular disease risk tracks more closely with LDL-P than LDL-C (15).
What should I do if I have high LDL-P?
For example, if you have a large number of LDL-P and they're small, the two best things to treat those are niacin and omega-3 fatty acids, and also getting a patient on a low-carbohydrate diet, particularly one that is low in sugar and refined carbohydrates.
How do you treat high LDL-P?
Can I reduce my amount of small, dense LDLs?Eat a diet very rich in soluble fiber (BYOBB) – Beans, Yams, Oats, Barley, and Berries.Eat fewer refined carbohydrates.Eat much less saturated and trans fats and cholesterol.Exercise regularly, and.Lose excess weight.
How do you calculate LDL and VLDL?
The LDL-C value is estimated using the FF, which can be transformed as follows: LDL-C (mg/dl) = Non-HDL-C - TG × 20%. In the formula, the concentration of very low-density lipoproteins (VLDL) is estimated as 20% of total TG concentrations [4].
How do you calculate LDL mmol L?
LDL-C concentrations were also calculated by Friedewald's formula [8]: F-LDL-C (mmol/L) = TC - HDL-C - TG/2.2 and by Anandaraja's formula [12] A-LDL-C (mg/dL) = 0.9*TC - 0.9*TG/5 - 28. Values in mg/dL were calculated and then expressed in mmol/L.
Why can't LDL be calculated?
As you may already know, the LDL cholesterol that is usually reported when a lipid panel is ordered is not measured but calculated. When the triglycerides are high, LDL cannot be accurately calculated because triglycerides are part of the equation.
How do you calculate HDL?
To obtain their total cholesterol HDL ratio, a person can divide their total cholesterol level by their HDL level. A higher ratio means a higher risk of heart disease. For example: 240 (total cholesterol) ÷ 60 (HDL) = 4 (total cholesterol HDL ratio).
What is the LDL calculator?
The LDL calculator estimates the amount of Low-Density Lipoproteins - complex particles that carry lipids in the blood. Their concentration is a very important parameter predicting the arteriosclerotic risk, but its direct measurement is not a part of the diagnostic routine. Instead, the patient's LDL is calculated and presented as LDL-C. It is universally accepted to use Friedewald equation to do so. Read on if you're curious how to calculate LDL cholesterol.
How to calculate LDL cholesterol?
After having the lipid profile measured, you can start the calculation. Check what units are your lab test results expressed in - it's important for the calculation.
What is the best cholesterol for stroke?
HDL - High-Density Lipoprotein - a.k.a. "the healthy cholesterol," is associated with lowering the build-up of plaque in the arteries in the process of atherosclerosis, which means it prevents cardiovascular disease and stroke. Its protective function is best when it's over 60 mg/dL.
What is the coordinate for cholesterol?
If your results are in millimoles per liter (mmol/L), use a coordinate of 0.45 or use our cholesterol unit converter. In the calculator, you can switch the units by clicking on their symbols.
Where is the calculated LDL cholesterol presented?
The calculated LDL cholesterol is presented in the last line.
What is the name of the blood test that measures cholesterol?
The values you need to insert in the equation are measurements from the standard cholesterol - focused blood test, called the lipid panel :
What is the best level of TG?
Its protective function is best when it's over 60 mg/dL. TG - triglycerides - they transport glucose and lipids in both ways between liver and fatty tissue. Their high levels are related to a high risk of atherosclerosis. Their level in a healthy person should be below 150 mg/dL.
What is LDL-P cholesterol?
Standard cholesterol lab work measures LDL cholesterol (LDL-C). This is a measure of the amount of cholesterol contained within LDL particles. LDL-P measures the actual number of LDL particles. Research shows LDL-P to be a stronger predictor of heart disease than LDL-C.
How to increase LDL?
Positive changes to particle sizes from exercise are not permanent and will “go away” within two weeks of ceasing activity. Studies have found exercise duration to be a greater factor than exercise intensity. Add 20-30-minutes of exercise to your daily (or almost daily) routine for positive, long term improvements to LDL particle size.
What are the two types of LDL particles?
LDL particles come in two main sizes: Large, fluffy particles and small, dense particles.
How to reduce LDL particle size?
Add 20-30-minutes of exercise to your daily (or almost daily) routine for positive, long term improvements to LDL particle size. Discuss niacin supplementation with your doctor. Niacin has been used to effectively raise HDL cholesterol levels and research suggests niacin can lower LDL-P.
Why is LDL cholesterol important?
LDL cholesterol level is often used to determine if preventative treatment is needed, such as medication to lower levels in an effort to prevent heart disease .
Is LDL cholesterol a good determinant of heart disease?
However, research indicates LDL cholesterol alone is not necessarily a good determinant of risk. LDL particles vary in their content, size, and density. Not all LDL particles impact heart disease risk in the same way.
Does statin lower LDL?
It’s important to note statin medication does not decrease small, dense LDL levels. Just because you lower LDL-C to normal levels with statin treatment, your risk for heart disease may remain elevated if your LDL-P is above normal.
What is LDL-P cholesterol?
LDL-Particle Number (LDL-P) LDL-cholesterol (LDL-C) lowering by statin therapy has historically been the focus of guidelines for treating cardiovascular disease (CVD ) risk associated with elevated blood cholesterol. Treatment with statins, while well proven to be effective and widely accepted, nevertheless leaves substantial residual risk.
What drugs reduce LDL-P?
Statins are the most potent drugs available to reduce LDL-P, by upregulating LDL receptors and increasing apoB particle clearance, but do not generally influence the size distribution of the LDL particles. Drugs that can reduce production of hepatic apoB- containing particles also shift LDL size upwards and include:
What is the most common scenario leading to CE depleted LDLs and high concentrations of LDL-P?
The most common scenarios leading to CE-depleted LDLs and high concentrations of LDL-P are small LDL size (even small changes in LDL particle diameter translate into significant volume changes and TG-rich LDL particles). Patients with high LDL-TG (not typically measured) have CE depleted LDLs and higher LDL-P (regardless of LDL size). A large LDL with a low CE/TG ratio will be associated with high LDL-P and a small LDL with a low CE/TG ratio will usually be associated with extreme LDL-P elevations.
How effective are statins in reducing cholesterol?
Statins are highly effective in reducing serum cholesterol through inhibition of HMG-CoA reductase, which upregulates LDL receptors (LDLr) and leads to increased clearance of LDL particles from the circulation. However, LDL receptors are not as effective in clearing small LDL particles compared to normal-sized LDLs.
Is LDL-C a surrogate marker?
Even though the total LDL-C concentration is often an effective surrogate marker for measuring LDL-P, LDL-C can correspond to a widely varying LDL-P number. The LDL-C concentration doesn’t account for the possibility of a high number of TG-rich LDLs (of any size) or small, dense LDL (sdLDL) particles that may be associated with a “normal” LDL-C level. 1,2 Because of this, there is good reason to look beyond just LDL-C and non-HDL-C levels and focus goals of therapy on other lipid parameters. 2-4
Is LDL-C elevated?
Even with normal or near-optimal LDL-C measurements, LDL-P concentration may be increased. Studies have shown that elevated LDL-P concentration is associated with increased risk for coronary heart disease ( CHD) even in the presence of optimal LDL-C values. 8 Small, dense LDL particles are often associated with the metabolic syndrome and prediabetes.
Is statin a predictor of cardiovascular disease?
Recent large clinical studies have shown that for statin-treated patients, non-HDL, apoB, and LDL-P levels are better predictors of cardiovascular outcomes than LDL-C measurement alone. 2 Cardiovascular disease risk is more directly related to the number of circulating atherogenic lipoprotein ( apoB) particles than to the total or LDL-C concentration. 2
What Is LDL-P and Why Is It Important?
LDL-C is usually calculated using the Friedewald equation. However, this measure can underestimate LDL-C level as triglycerides increase. Direct LDL-C measurements are also available and better reveal individual issues, but are less often promoted or done due to slightly higher costs.
What is the LDL particle?
LDL is the lipoprotein particle that is mostly involved in atherosclerosis. LDL particles exist in different sizes. On the one hand there are the large, fluffy, cotton-ball like molecules, and on the other hand the small dense molecules. Many recent studies have looked into the importance of LDL-particle size.
What is the correlation between LDL and triglycerides?
Thus, the higher your triglycerides, the greater the number of small LDL parti cles. Conversely, the lower your triglycerides, the higher the number of large, fluffy LDL particles.
What are the two major lipoproteins that enable the transport of different fat molecules, including cholesterol?
HDL and LDL are two of five major lipoproteins that enable transport of different fat molecules, including cholesterol. The other lipoproteins are chylomicrons, IDL (intermediate density lipoprotein) and VLDL (very low-density lipoprotein, mainly triglycerides). LDL is the lipoprotein particle that is mostly involved in atherosclerosis.
What does LDL-C mean?
LDL-C reflects the total content or concentration of cholesterol within LDL-C particles in mg/dl or mmol/L. Since the amount of cholesterol in each particle may vary, measuring LDL-C does not necessarily reflect the actual number of particles. LDL-P (LDL particle number) measures the actual number of LDL particles (particle concentration, nmol/L).
Which is better, Apolipoprotein B or LDL-P?
Apolipoprotein B (apoB) and LDL-P, on the other hand, reflect the number of atherogenic particles, with no mention of cholesterol mass. Therefore apoB and LDL-P are believed to be better risk predictors than LDL-C.
How long does it take to read a blood lipid?
Estimated reading time: 5 minutes. Counseling patients on the role of blood lipids (fats) and their association with the risk of cardiovascular disease (CVD) can be a difficult task. There are many types of lipids, and most of them play a major role in bodily functions. Nonetheless, some lipid measurements may reflect an increased risk ...
What is LDL C?
The level of low-density lipoprotein-cholesterol (LDL-C), among other factors, correlates with the likelihood of developing atherosclerotic cardiovascular disease (ASCVD). Thus, LDL-C measurement is useful for assessing ASCVD risk, stratifying individuals into treatment benefit groups, and monitoring risk-reduction therapy. 1
Why is low LDL-C more accurate?
The improved accuracy at low LDL-C allows more accurate assessment of patients in the high-risk categories undergoing aggressive treatment with low LDL goals. In addition, the ability to adjust for high triglyceride levels may improve reliability of LDL-C estimation when fasting is not desired or practical. 8 This can be convenient for risk assessment, especially for patients who have difficulty fasting (eg, young children and people with diabetes). 8
Does fasting affect LDL-C?
The need for fasting varies with the indication for testing, and the method used to calculate LDL-C should not affect the decision to require fasting samples. However, as noted above, the ability of the Martin-Hopkins calculation to adjust for high triglyceride levels may also make LDL-C estimation more reliable in nonfasting patients. 8
Is fasting required for lipid profile?
Nordestgaard BG, Langsted A, Mora S, et al. Fasting is not routinely required for determination of a lipid profile: clinical and laboratory implications including flagging at desirable concentration cutpoints-a joint consensus statement from the European Atherosclerosis Society and European Federation of Clinical Chemistry and Laboratory Medicine. Clin Chem. 2016;62:930-946.
Can Friedewald equation be used to calculate LDL-C?
Although the Friedewald equation it is still widely used and generally produces reliable results, it may underestimate LDL-C at the low LDL-C levels that modern treatment guidelines call for and therapies can achieve ( eg, <70-100 mg/dL). 3 PCSK-9 inhibitors can drive LDL-C levels even lower (eg, <40 mg/dL). Such low LDL-C concentrations are below the concentrations considered when the Friedewald equation was developed. 2
What is the Trig HDL ratio?
The Trig:HDL ratio provides additional valuable information regarding CHD risk in that it provides an indirect measure of insulin resistance. A brief review: insulin is a hormone produced by the beta cells of the pancreas. Its main role is to assist in the transport of glucose and amino acids from the blood into the cells. Insulin resistance is a condition where a normal insulin production leads to a sub-normal uptake of blood glucose by the tissues. Therefore, people who are insulin resistant tend to have elevated blood glucose levels, and are much more likely to develop prediabetes and type 2 diabetes than people who are not insulin resistant. A high Trig:HDL ratio is usually a good indicator of the presence of insulin resistance. Using the examples above and with all other factors being equal, Steve would be much less likely to have insulin resistance than Michelle. Therefore, Steve would be at a lower risk of developing CHD than Michelle.
How many people have abnormal cholesterol?
With approximately 100 million Americans having abnormal blood cholesterol levels, it is no wonder that statin drugs are one of the most commonly prescribed medications in our society. What you may not know about LDL-cholesterol is that not all LDLs are the same.
How to lower blood triglyceride?
Adding to this an increased intake of unrefined plant-based foods and reduced-fat dairy will often help to decrease elevated blood triglyceride levels, improve insulin function, and reduce resting blood pressure if it is elevated. All of these steps would then be associated with an improved Trig:HDL ratio, larger/more fluffy LDLs, decreased risk of prediabetes and type 2 diabetes, and ultimately a decreased risk of CHD.
What is the bad cholesterol?
Thursday, Dec 10, 2015. Just about anyone who is health-conscious knows that LDL-cholesterol is nicknamed ‘the bad cholesterol’. It has long been known that individuals with elevated levels of LDL face an increased risk of coronary heart disease (CHD), which can result in heart attack, coronary artery bypass surgery, or stent placement.
Does exercise increase HDL cholesterol?
Yes, and that is a huge understatement! Exercise helps to increase HDL-cholesterol levels and decrease blood triglyceride levels. It also helps to convert the small and dense LDLs into the larger/fluffier LDLs, and makes insulin work better.
Is the Trig:HDL ratio accurate?
However, scientists in the mid-1990s found that in most people, the ratio of blood triglyceride level to HDL-cholesterol level (known as the Trig:HDL ratio) provides an indirect but reasonably accurate estimate of LDL-cholesterol particle size. Here are two examples:
Does the doctor know your LDL?
At this point, you may be thinking to yourself that your doctor has never mentioned your LDL particle size. Most labs at the present time simply report the overall LDL value instead of providing information about LDL particle size. Historically, this has been a cost issue more than anything else. However, scientists in the mid-1990s found that in most people, the ratio of blood triglyceride level to HDL-cholesterol level (known as the Trig:HDL ratio) provides an indirect but reasonably accurate estimate of LDL-cholesterol particle size. Here are two examples:
What does LDL stand for in a cell?
LDL stands for low density lipoprotein, and it delivers fat molecules to cells. VLDL, along with LDL, is considered "bad cholesterol" as it builds upon the walls of arteries.
How to calculate VLDL?
From the triglycerides, we can calculate VLDL using Friedewald's equation. VLDL = triglycerides / 5.
What is VLDL (Very Low Density Lipoprotein)?
Below are some interesting pieces of information about very low density lipoprotein (VLDL):
What happens to VLDL after it is in circulation?
Once in circulation, VLDL will come in contact with lipoprotein lipase (LPL), and after various transformations , the composition of the molecule changes, becoming a intermediate-density lipoprotein (IDL ). Around half of IDLs are recognized by receptors in the liver cells and are endocytosed (brought into the cell).
What are the different types of VLDL?
Below are some interesting pieces of information about very low density lipoprotein (VLDL): 1 They're one of the five major groups of lipoproteins (chylomicrons, VLDL, IDL, LDL, HDL); 2 They enables fats and cholesterol to circulate in the bloodstream, a water-based solution; 3 They're produced in the liver from triglycerides, cholesterol, and apolipoproteins; and 4 Their main function is the transport of endogenous products: triglycerides, phospholipids, cholesterol, and cholesteryl esters.
How much triglycerides are in a VLDL?
This formula was created by Friedewald and collaborators and allows VLDL to be estimated for triglycerides concentration up to 400 mg/dL (4.5 mmol/L).
What is the normal VLDL level?
Our patient's VLDL cholesterol is 25 mg/dL. This result is within the normal range for VLDL levels.
