Columbus, OH The Ohio State University. Paul Ridker. Inflammation is part of the body's natural response to protect itself against harm. There are two types: acute and chronic. The acute type occurs when you have an injury or infection. This short-lived reaction rids the body of harmful intruders and repairs damaged cells.

Chronic inflammation, on the other hand, can develop as a response to long-term exposure to unwanted substances in the body, such as toxins from cigarette smoke or an excess of fat tissue, especially around the midriff.

Chronic inflammation is important to heart health because it plays a pivotal role in the development of atherosclerosis — the buildup of fatty, cholesterol-rich plaque inside the arteries. Your body perceives this plaque as foreign, so it initiates an inflammatory response to contain the damage.

Chemical messengers called cytokines draw white blood cells to the area to consume the cholesterol particles and to wall off the plaque from the flowing blood. But if that wall breaks down, the plaque may rupture. The contents then mingle with blood, forming a clot that could block blood flow.

These clots are responsible for most heart attacks and strokes. The more than 10, patients enrolled in the CANTOS trial had already suffered a heart attack.

They also had high levels of C-reactive protein, a biomarker signaling bodywide inflammation see "What your CRP test results mean". All were taking standard heart drugs, but some also took varying doses of the drug canakinumab Ilaris.

Canakinumab was not originally developed as a heart medicine; it's a specialized monoclonal antibody used to treat a rare autoimmune disorder in children.

It disrupts the inflammatory process by neutralizing a specific cytokine that is instrumental in the progression of atherosclerosis. This held true even though the canakinumab did not lower lipid levels or affect any other traditional heart risk factor, says Dr.

Your liver makes C-reactive protein CRP in response to inflammation. Low levels of this protein indicate the subtle, chronic inflammation that reflects unhealthy changes in artery walls.

Doctors check for CRP levels using a high-sensitivity C-reactive protein hsCRP test, which requires only a small amount of blood. The results signal three categories of risk:.

It will probably take months for the CANTOS results to make their way into clinical practice, Dr. Libby predicts. Canakinumab is already approved for other populations, but it has some notable side effects, including a greater risk of serious infections.

In the meantime, another study is testing the effectiveness of low-dose methotrexate in cardiovascular disease. In contrast to canakinumab, methotrexate is a generic, inexpensive drug commonly used to treat rheumatoid arthritis.

Results from this trial, also led by Dr. Ridker, should be available within the next few years. Research suggests that among people with normal cholesterol, those with increased CRP levels have several times the risk of heart problems compared with those who have low CRP. Until now, many doctors have been reluctant to recommend CRP testing as part of routine care because they believed the results wouldn't have an effect on treatment choices.

However, new drug therapies that specifically target cardiovascular inflammation will open the door to wider use of CRP testing, Dr.

Learn why RA puts you at a Inflammatlon risk for Inflammatino disease and what you can do Sustainable weight maintenance protect yourself. People Ehart RA are almost twice as likely to develop heart disease as those without the condition. Having RA makes you more likely to experience a serious cardiovascular event like a heart attack or stroke. With the right screening and preventive measures, you can keep your heart and blood vessels healthy. Two factors come together to increase your risk: chronic inflammation and shared risk factors.

Inflammation and heart disease -

Or what about the guy who ran a marathon on Saturday, never having any chest pain during the race, finished with a good time, and then three days later climbed a flight of stairs, felt a squeezing sensation in the middle of his chest, and suddenly dropped dead?

On Saturday, his coronary arteries had been wide open — open enough to push his heart to its max for 26 miles over 3.

But just three days later, at least one artery became completely blocked: climbing one flight of stairs killed him. We now understand why. As cholesterol invades the wall of the artery, the immune system treats it like it treats other invaders.

Immune system cells infiltrate the wall of the artery. They release inflammation-producing chemicals and send signals calling for other cells to come remove the cholesterol from the artery wall. Then a fibrous cap forms over the plaque. Inflammation inside the plaque can eventually eat away at that fibrous cap.

If the cap ruptures, the cholesterol and the inflammatory cells and chemicals in the plaque suddenly spill into the artery, causing a blood clot to form and block blood flow.

If even a little plaque — one not large enough to block blood flow by itself — suddenly ruptures, it can stop blood flow completely. The test for inflammation your doctor probably used called hsCRP was first studied here at Harvard Medical School.

And it was researchers here who showed that statin drugs work by reducing inflammation as well as by lowering cholesterol; and that drugs that reduce inflammation only, and don't lower cholesterol, still reduce heart attack risk. In August , another drug that works only on inflammation called colchicine Colcrys, Gloperba also was shown to prevent heart disease.

So your doctor is right: inflammation is an important contributor to heart attacks. As a service to our readers, Harvard Health Publishing provides access to our library of archived content. Please note the date of last review or update on all articles.

Is there more to a healthy-heart diet than cholesterol? Cells or drugs? The race to regenerate the heart. Crackdown on skin-colour bias by fingertip oxygen sensors is coming, hints FDA.

Researchers suspect this may be because patients taking TNF blockers have better controlled inflammation and use fewer corticosteroids and nonsteroidal anti-inflammatory drugs. Nonsteroidal anti-inflammatory drugs NSAIDs also increase the risk of heart attack and stroke.

In , the FDA cautioned they can lead to life -threatening heart events within just a few weeks of use. The risk increases with longer use and higher doses. If you do take an NSAID, use the smallest possible amount for the shortest period of time needed to manage your symptoms. Corticosteroids, like prednisone.

Though prednisone lowers inflammation, it can also raise blood pressure, increase cholesterol levels and harden the arteries, in addition to having a number of other serious side effects. To protect your heart, vision, bones and overall health, try to avoid corticosteroids as much as possible.
