Ldl Cholesterol Levels Are A Major Factor In Risk For Cardiovascular Disease

New guidelines on assessing peoples risk for cardiovascular disease emphasize the importance of LDL cholesterol. For those with known heart disease whose LDL is 70 mg/dl or higher, medication can help bring levels down. Likewise, people without heart disease whose LDL is above 190 in two separate readings should be evaluated for an inherited condition called familial hypercholesterolemia and develop a treatment plan.

Emergence Of Dietary Guidance On Fat Intake

It was from the perspective of this accumulating scientific evidence linking dietary fats and disease that the impetus arose to recommend a lowering of fat intake by Americans. The Dietary Goals for the United States, published by the U.S. Senate Select Committee on Nutrition and Human Needs , suggested numerical goals, including reduction of total fat intake to 30% of energy, 10% of energy from SFA and 300 mg/d of cholesterol. Similar targets for intake of fats were first promoted by the American Heart Association , a voluntary health association .

A recent historical account of the development of the Dietary Guidelines, presented by Michael McGinnis at a Dietary Guidelines Advisory Committee meeting in 1998, suggests that the Dietary Goals for the U.S., and in particular their quantified nutrient targets, prompted the two departments, the USDA and the Department of Health and Human Services , to consider descriptive Dietary Guidelines for the American people .

What Factors Affect Cholesterol Levels

A variety of factors can affect your cholesterol levels. They include:

• Diet: Saturated fat, trans fat and cholesterol in the food you eat increase cholesterol levels. Try to reduce the amount of saturated fat, trans fat and cholesterol in your diet. This will help lower your blood cholesterol level. Saturated and trans fat have the most impact on blood cholesterol.
• Weight: In addition to being a risk factor for heart disease, being overweight can also increase your triglycerides. Losing weight may help lower your triglyceride levels and raise your HDL.
• Exercise: Regular exercise can lower total cholesterol levels. Exercise has the most effect on lowering triglycerides and raising HDL. You should try to be physically active for 30 minutes on most days of the week.
• Age and sex: As we get older,cholesterol levels rise. Before menopause, women tend to have lower total cholesterol levels than men of the same age. After menopause, however, womens LDL levels tend to rise and HDL can drop.
• Heredity: Your genes partly determine how much cholesterol your body makes. High blood cholesterol can run in families.

Numerical Goals For Dietary Fats

The 1990 DGAC report indicates agreement with numerical goals for dietary fats with the conclusion that widely based population data supplemented the evidence from clinical trial research, which at the time had been conducted predominantly in white males. The totality of the evidence was such that the goals were considered to be appropriate for the total population, not just persons at risk for heart disease.

The 1990 DGAC concluded that the potential benefits in reducing risk of CHD and some types of cancer by reduction in total fat, SFA and cholesterol were sufficient to support numerical goals for all healthy adults. The numerical goals for total fat and SFA related to the two food components considered to be of greatest significance to the health of Americans. The goals adapted, those of the National Research Council, the NCEP, and by history, the AHA, are total fat 30% of energy and SFA < 10% of energy.

The numerical goal for total fat is based on expected beneficial effects. A reduction of total fat would facilitate reduction of SFA and benefit CHD reduction; a limit on total fat was thought to be useful to reduce the risk of some types of cancer and help manage energy intake, thus helping to curb overweight and obesity.

Explanation:-

The buffer solution is made up of a weak base and its conjugate acid .

Plasma Transport And Regulation Of Absorption

As an isolated molecule, cholesterol is only minimally soluble in water, or hydrophilic. Because of this, it dissolves in blood at exceedingly small concentrations. To be transported effectively, cholesterol is instead packaged within lipoproteins, complex discoidal particles with exterior amphiphilic proteins and lipids, whose outward-facing surfaces are water-soluble and inward-facing surfaces are lipid-soluble. This allows it to travel through the blood via emulsification. Unbound cholesterol, being amphipathic, is transported in the monolayer surface of the lipoprotein particle along with phospholipids and proteins. Cholesterol esters bound to fatty acid, on the other hand, are transported within the fatty hydrophilic core of the lipoprotein, along with triglyceride.

There are several types of lipoproteins in the blood. In order of increasing density, they are chylomicrons, very-low-density lipoprotein , intermediate-density lipoprotein , low-density lipoprotein , and high-density lipoprotein . Lower protein/lipid ratios make for less dense lipoproteins. Cholesterol within different lipoproteins is identical, although some is carried as its native “free” alcohol form , while others as fatty acyl esters, known also as cholesterol esters, within the particles.

Myth: Eating Foods With A Lot Of Cholesterol Will Not Make My Cholesterol Levels Go Up

Fact:;It can be complicated. We know that foods with a lot of cholesterol usually also have a lot of saturated fat. Saturated fats can make your cholesterol numbers higher, so its best to choose foods that are lower in saturated fats. Foods made from animals, including red meat, butter, and cheese, have a lot of saturated fats.

Instead, aim to eat foods with plenty of fiber, such as oatmeal and beans, and healthy unsaturated fats, such as avocados, olive oil, and nuts. Learn more about healthy diets and nutrition at CDCs nutrition, physical activity, and obesity website.

How Is High Cholesterol Treated

There are several ways to lower high blood cholesterol , including lifestyle changes or medication, or both. Your healthcare provider will work with you to determine which therapy is best for you.

Lifestyle modifications

Healthcare providers like to start with the least invasive treatments when possible, such as lifestyle changes. Youll be advised to:

• Avoid tobacco. If you do smoke, quit. Smoking is bad for you in many ways, and reducing your level of good cholesterol is one of them.
• Change the way you eat. Limit the amount of trans fats and saturated fat. Eat heart-healthy foods like fruits, vegetables, poultry, fish and whole grains. Limit red meat, sugary products and dairy products made with whole milk.
• Get more exercise. Try to get about 150 minutes of physical activity every week, or about 30 minutes per day for most days of the week.
• Keep a healthy weight. If you need to lose weight, talk to your healthcare provider about safe ways to do this. Youll see results even before you reach your ideal weight. Losing even 10% of your body weight makes a difference in your cholesterol levels.
• Reduce the effect of negative emotions. Learn healthy ways to deal with anger, stress or other negative emotions.
• Control blood sugar and blood pressure. Make sure you follow your healthcare providers instructions for blood sugar levels, especially if you have diabetes, and for keeping blood pressure in the healthy range.

Medications

• Atorvastatin .
• Simvastatin .
• Pitavastatin .

What Is The Difference Between Laboratory And Point

Traditionally, cholesterol tests have been done in laboratories where clear procedures are in place for proper sample collection and analysis. These mechanisms help make sure that rest results are reliable.

New technologies have made point-of-care and at-home tests more widely available. When their instructions are correctly followed, these tests have nearly the same accuracy as laboratory tests.

For at-home and point-of-care tests, blood is taken from your fingertip instead of from a vein in your arm. Because results do not need to be sent to a laboratory, results are provided within minutes instead of days.

Laboratory testing is considered to be standard and is what doctors rely on to make medical decisions. That said, at-home and point-of-care tests are convenient and may help with ongoing monitoring of cholesterol.

In 2014 735 Million People Have High Cholesterol What Percentage Of Those People Are Getting Treatment To Lower Those Levels

Is it a) about 70% b) about 60% c) about 50% or d) about 40%?

According to the CDC, just a little less than half of adults with high LDL cholesterol are getting treatment. So, the correct answer is C. This is not good because people with high cholesterol are twice the risk for developing heart disease as those with ideal levels.

Who Should Be Tested

Your GP may recommend that you have your blood cholesterol levels tested if you:

• have been diagnosed with coronary heart disease, stroke or mini-stroke , or peripheral arterial disease
• are over the age of 40;;people over 40 should have their estimate of CVD risk reviewed regularly
• have a family history of early cardiovascular disease; for example, if your father or brother developed heart disease or had a heart attack or stroke before the age of 55, or if your mother or sister had these conditions before the age of 65
• have a close family member who has a cholesterol-related condition, such as familial hypercholesterolaemia
• are overweight or obese
• have high blood pressure or diabetes
• have another medical condition, such as kidney disease, an underactive thyroid, or an inflamed pancreas ; these conditions can cause increased levels of cholesterol or triglycerides

What Do I Need To Know About Having My Cholesterol Levels Checked

Adults 20 to 45 years of age should have their cholesterol levels checked every 4 to 6 years. Adults 45 years or older should have their cholesterol checked every 1 to 2 years. You may need your cholesterol checked more often, or at a younger age, if you have risk factors for heart disease. You may also need to have your cholesterol checked more often if you have other health conditions, such as diabetes. Blood tests are used to check cholesterol levels. Blood tests measure your levels of triglycerides, LDL cholesterol, and HDL cholesterol.

How Can I Lower My Cholesterol Level

The first step in reducing your cholesterol is to maintain a healthy, balanced diet. It’s important to keep your diet low in fatty food.

You can swap food containing saturated fat for fruit, vegetables and wholegrain cereals. This will also help;prevent high cholesterol returning.

Other lifestyle changes, such as;taking regular exercise and;giving up smoking, can also make a big difference in helping to lower your cholesterol.

If these measures don’t reduce your cholesterol and you continue to have a high risk of developing heart disease, your GP may prescribe a cholesterol-lowering medication, such as statins.

Your GP will take into account the risk of any side effects from statins. The benefit of lowering your cholesterol must outweigh any risks.

Myth: All Cholesterol Is Bad For You

Fact:;Some types of cholesterol are essential for good health. Your body needs cholesterol to perform important jobs, such as making hormones and building cells. Cholesterol travels through the blood on proteins called;lipoproteins. Two types of lipoproteins carry cholesterol throughout the body:

• LDL ,;sometimes called bad;cholesterol,;makes up most of your bodys cholesterol. High levels of LDL cholesterol raise your risk for heart disease and stroke.
• HDL ,;or good;cholesterol,;carries cholesterol back to the liver. The liver then flushes it from the body. High levels of HDL cholesterol can lower your risk for heart disease and stroke.

When your body has too much LDL cholesterol, it can build up in the walls of your blood vessels. This buildup is called;plaque. As your blood vessels build up plaque over time, the insides of the vessels narrow. This narrowing can restrict and eventually block blood flow to and from your heart and other organs. When blood flow to the heart is blocked, it can cause angina or a heart attack.

When Should You Contact Your Healthcare Provider About Your Cholesterol Levels

In truth, your healthcare provider will probably talk to you about your numbers first. As always, contact your provider if you have any new or worsening pain or other uncomfortable feelings. Make sure you know what medications you take and what they are expected to do. Call the provider if you have a reaction to the medicine.

Before you go to the office, and after you have had a cholesterol test, it helps to have a list of questions prepared about your test results and any proposed treatment.

A note from Cleveland Clinic

When considering cholesterol numbers, its important to remember that you really have the ability to make those numbers go in your favor. What you choose to eat, how much you are able to move and how you deal with lifes ups and downs are things that you can influence.
