Its known as a silent killer, but high cholesterol doesnt have to go undetected. A simple blood test, known as a lipid panel, can determine if an individual has dangerous cholesterol levels and if that risk could lead to a sudden heart attack or stroke.

The test could save your life. And this September, observed each year as National Cholesterol Education Month, could serve as your annual reminder to get tested.

You cant feel cholesterol in your bloodstream, so theres no way to sense if it is high or if its low. You dont even know if youre building up plaques. What you feel is when you have a heart attack, and thats very late in the disease process, saidChristie Mitchell Ballantyne, M.D., cardiology chief for the department of medicine at Baylor College of Medicine. You could have had high cholesterol for 60 years and be building up plaque, and then one of the plaques ruptures or develops a blood clot, blocks off the arteries, and then you have a heart attack. Unfortunately, no matter how in tune you are with your body, you cant know what your cholesterol level is unless you get it checked.

Cholesterol is a fat-like substance that, when in excess, can build up in a persons arteries and settle as a form of plaque, eventually narrowing those arteries. According to the Centers for Disease Control and Prevention (CDC), more than 102 million adults in the United States 20 or older have total cholesterol levels at or above 200 mg/dL. A healthy level is considered to be 170 mg/dL or less.

Getting tested, Ballantyne said, is the first step to taking control of your health. He explained that the lipid profile measures both types of cholesterolLDL and HDL. LDLwhich stands for low-density lipoproteinis the type known as bad cholesterol, which leads to clogged arteries. HDL, which stands for high-density lipoprotein, is known as good cholesterol and helps transport cholesterol to the liver to be expelled from the body and away from the arteries, and indicates the level of triglycerides, which is a type of fat found in the blood.

If you have a high triglyceride result, thats bad, but if you have a high cholesterol result, you need to know why it is high, Ballantyne said. It might be high because you have a high level of the good cholesterol, which can happen for people who are extremely healthy or have good genes.

He added that having a high triglyceride result plus high LDL, or bad cholesterol, can be especially harmful and that their presence is typically accompanied by conditions such as diabetes, obesity and high blood pressure. Because these levels can change throughout a persons lifetime based on age and lifestyle, experts recommend that adults get a lipid panel every five years.

But high cholesterol isnt just attributed to age, smoking, poor diet and a lack of exercise; some cases are grounded in genetics.

There is another lipid test thats moving into the mainstream which looks for the presence of lipoprotein(a), Ballantyne said.

Lipoprotein(a) is emerging in the scientific literature as a reliable independent risk factor for having a cardiovascular event. Like cholesterol, there are no symptoms of its presence in the blood.

It turns out that it is hereditary, so there is a genetic factor, and we know that in certain populations, levels are higher, Ballantyne said, adding that, importantly, lipoprotein(a) does not show up on a regular lipid panel.

You may have to ask for the test, but everyone should get tested at least once in their lifetime, Ballantyne said, echoing the newest recommendation from the European Society of Cardiology, which was released in August.

Once a person is tested for cholesterol levels and additional risk factors, including elevated lipoprotein(a), the next step is to work on reducing cholesterol if it is found to be higher than the normal range.

Know your numbers, see what your risk is, know your family history, and then make a plan, Ballantyne said, citing diet and exercise, smoking cessation and considering medications.

We have really good medications for these problems nowlots of generic, inexpensive medications that are easy to take with very few side effects, he said. That doesnt mean everybody is easy to treat, but, in general, people can really do a tremendous amount with diet and exercise and simple, inexpensive, generic medications.

According to the CDC, an ideal diet for maintaining healthy cholesterol levels includes one that is low in fat and high in fiber, with plenty of fresh fruits, vegetables and whole grains. Ballantyne added that individuals should especially stay away from highly-processed carbohydrates.

The big culprit in the American diet is usually not actually cholesterol but too many carbohydrates, particularly simple carbohydrates, and also too much saturated and trans fat, he said. Unfortunately, if you take a look at peoples snack foods, its potato chips, which is basically carbs, fat and salt. A lot of our processed foods are very high in carbohydrates and saturated fat, so youve really got to go through your diet and clean it up.

Ballantyne added that to reduce the risk of vascular diseases, a person should look at their health as a whole, with cholesterol being just one factor. Age, obesity, high blood pressure, diabetes, glucose levels and smoking should all be addressed, he said, for optimal cardiovascular health.
