What Are The Risk Factors For High Levels Of C

C Reactive Protein Test What does it mean?

Heart disease has an inflammatory component, which may be linked to high C-reactive protein levels. However, based on the current available data it cannot be considered an independent risk factor for cardiovascular disease.

Based on the review of the published data, the CDC and the American Heart Association have recommended the following guidelines for assessment of cardiovascular disease risk:

  • CRP levels of 1 mg per liter or lower are considered low risk for cardiovascular disease.
  • CRP levels of 1-3 mg per liter are considered moderate risk for cardiovascular disease.
  • CRP levels greater than 3 mg per liter are considered high risk for cardiovascular disease.
  • CRP levels greater than 10 mg per liter may suggest an acute coronary process, such as heart attack .

The known risk factors for cardiovascular disease are:

This may be possibly related to ongoing inflammatory atherosclerosis in these individuals because of their risk factors.

Despite these associations, research has not clearly and consistently established c-reactive protein as an independent risk factor for cardiovascular disease, as the data seem to be inconsistent from different studies. It has been proposed that elevated c-reactive protein is an independent predictor of atherosclerosis among healthy men and women.

How Does Crp Relate To Cardiovascular Risk

Your level of C-reactive protein can be an indicator of how at risk you are for developing cardiovascular problems. This is because the development of atherosclerosis is associated with inflammation within the vessel walls. The result is higher levels of CRP in patients with atherosclerosis than in those without atherosclerosis.

The value of knowing CRP levels depends on whether you fall into one of three cardiovascular risk groups:

  • Low risk because of low cholesterol levels and little history of risk factors that is, no diabetes, high blood pressure, or smoking, and no family history of heart attacks at an early age. Even a higher level of CRP will probably not put you at a level of risk that requires than lifestyle changes.
  • Intermediate risk helpful to know CRP level, because it can provide missing piece of information for physician deciding next step in treatment
  • High risk not essential to know your CRP, because you should already be combining aggressive treatment with lifestyle changes to lower your risk

How Does Deep Cleaning Treat Periodontitis

During a deep cleaning, your provider removes plaque. Providers use methods called scaling and root planing, which they may do with a laser:

  • Scaling scrapes off the tartar from above and below the gum line.
  • Root planing gets rid of the rough spots on the roots of the teeth. It helps remove the bacteria that cause periodontitis.

What Is A C

A c-reactive protein test measures the level of c-reactive protein in your blood. CRP is a protein made by your liver. It’s sent into your bloodstream in response to inflammation. Inflammation is your body’s way of protecting your tissues if you’ve been injured or have an infection. It can cause pain, redness, and swelling in the injured or affected area. Some autoimmune disorders and chronic diseases can also cause inflammation.

Normally, you have low levels of c-reactive protein in your blood. High levels may be sign of a serious infection or other disorder.

Other names: c-reactive protein, serum

How To Treat And Prevent Elevated Levels


C-reactive protein treatment depends on what the underlying cause of the inflammation is. The best way to naturally treat high levels is to uncover the root cause of someones inflammatory response and then make lifestyle or medication recommendations based on that finding.

The same types of healthy habits that help protect against heart disease, such as eating a balanced diet, not smoking and exercising, are also usually involved in treatment for high CRP levels are.

1. Eat An Anti-Inflammatory Diet

In order to protect against the effects of inflammation on your heart and elsewhere, its recommended that you eat a whole-foods diet such as the Mediterranean diet. This type of nutrient-dense diet includes plenty of vegetables, fruits, fresh herbs, fish, whole grains, legumes and nuts.

Eating foods high in antioxidants, such as vitamin C, A and E, plusprobiotic foods can help to support your immune system. One study found that high intake of vitamin C helped to reduce CRP levels in people with levels greater than 1 mg/L.

Its also important to address any food allergies you may be suffering from, as well as to avoid foods that trigger flair-ups if you have inflammatory bowel disease. These foods can include: gluten, dairy, caffeine, alcohol and others depending on the person.

2. Get Regular Exercise

3. Talk to Your Doctor About Your Medication Use

If an infection is the root cause of your elevated CRP, then antibiotics may be needed to help you recover.

Coronary Heart Disease Risk

Arterial damage results from white blood cell invasion and inflammation within the wall. CRP is a general marker for inflammation and infection, so it can be used as a very rough proxy for heart disease risk. Since many things can cause elevated CRP, this is not a very specific prognostic indicator. Nevertheless, a level above 2.4 mg/L has been associated with a doubled risk of a coronary event compared to levels below 1 mg/L however, the study group in this case consisted of patients who had been diagnosed with unstable angina pectoris whether elevated CRP has any predictive value of acute coronary events in the general population of all age ranges remains unclear. Currently, C-reactive protein is not recommended as a cardiovascular disease screening test for average-risk adults without symptoms.

The American Heart Association and U.S. Centers for Disease Control and Prevention have defined risk groups as follows:

  • Low Risk: less than 1.0 mg/L
  • Average risk: 1.0 to 3.0 mg/L
  • High risk: above 3.0 mg/L

But hs-CRP is not to be used alone and should be combined with elevated levels of cholesterol, LDL-C, triglycerides, and glucose level. Smoking, hypertension and diabetes also increase the risk level of cardiovascular disease.

What Happens When You Have Periodontitis

Periodontitis causes your gums to become very inflamed. They may turn red, swell and bleed. The inflammation is so severe that pockets of air also develop between your gums and teeth.

Bacteria enter and flourish in these pockets, leading to infection below the gum line. Your immune system then starts to fight the infection. It eventually breaks down the tissue and bone holding teeth in place. This response can lead to the loss of teeth.

What Is Crp Test

C-reactive protein test is also called CRP test, is a general blood test that checks for infection or inflammation in the body. C-reactive protein test is used to determine the severity of inflammation and to monitor whether you are responding to treatment. C-reactive protein is an acute phase reactant, a protein made by the liver and released into the blood within a few hours after tissue injury, the start of an infection, or other cause of inflammation as well as following a heart attack, surgery, or trauma. Markedly increased C-reactive protein levels are observed, for example, after trauma or a heart attack , with active or uncontrolled autoimmune disorders, and with serious bacterial infections like sepsis. The level of CRP can jump as much as a thousand-fold in response to inflammatory conditions, and its rise in the blood can precede pain, fever, or other clinical indicators. Thus, C-reactive protein is one of several proteins that are often referred to as acute phase reactants. The C-reactive protein test measures the amount of CRP in the blood and can be valuable in detecting inflammation due to acute conditions or in monitoring disease activity in chronic conditions. However, CRP blood test does not show where the inflammation is in your body. A more sensitive form of the C-reactive protein test is called the high-sensitivity C-reactive protein , that is used to assess your risk of heart disease.

C-Reactive protein (CRP) test

After assessing your symptoms and performing a physical exam, your healthcare provider may order one or more of these tests:

  • Blood tests: A complete blood count checks for signs of inflammation and infection. A blood culture looks for bacteria in your bloodstream.
  • Imaging tests: X-rays, MRIs, CT scans and ultrasounds provide images of your bones, muscles and tissues.
  • Bone scan: A bone scan uses a small amount of safe, radioactive material to identify infections or fractures during an imaging scan.
  • Biopsy: Your healthcare provider performs a needle biopsy to take samples of fluid, tissue or bone to examine for signs of infection.

Inflammation Causes Heart Attacks

Experts who study blood vessels, plaque, and heart attacks in minute detail have been developing an inflammatory explanation for heart attacks. They’ve described a process quite different from the clogged plumbing analogy. Blood vessels aren’t solid pipes, but slender tubes of layered, living tissue, some of it quite delicate. LDL cholesterol doesn’t simply lodge in arterial walls-it injures them. And like injuries elsewhere in the body, this stirs up an inflammatory response. Swarms of cytokines, macrophages, and other cells swoop in. They enlarge and transform deposits of LDL cholesterol into accumulations of fat-laden foam cells sealed by fibrous caps of collagen.

Other inflammatory molecules can so weaken a fibrous cap that eventually it bursts open. The contents of the plaque spill out and activate clotting factors in the blood. A massive blood clot forms. The result: a blocked artery and a heart attack.

Who Is At Risk For Periodontitis

Periodontitis is fairly uncommon in people under age 30. Still, it can affect anyone with poor oral hygiene those who dont brush their teeth and floss regularly.

Periodontitis is more likely to happen as you age, though. Thats because years of poor oral hygiene take their toll. Before you get periodontitis, youll develop gingivitis, a less severe form of gum disease. If you dont get treatment for gingivitis, periodontitis can happen.

Men are also more likely to get periodontitis. One possible reason is that men are less likely to get regular dental care. They also tend to have worse dental health.

Other factors that can increase your periodontitis risk include:

  • Smoking , since it weakens the bodys ability to fight infection.
  • Diabetes, since people with diabetes are at higher risk for developing infections.
  • Medications that lower the production of saliva, which protects your gums. These medicines include antihistamines, antidepressants and drugs for hypertension .
  • Genetics you may have genes that put you at higher risk.
  • Hormonal changes in women, such as pregnancy or using birth control pills.
  • Diseases that limit the immune systems response, such as cancer or AIDS. These conditions can lead to necrotizing periodontitis, the most severe form.

How Long Does Crp Levels Take To Normalize

Usual levels of C reactive protein in blood is less than 5 mg/L. Within 4-6 hours of the inflammatory stimulus, secretion of CRP starts rising, which doubles every 8 hours and peaks within 36 72 hours, and returns to normal around 3 days after the stimulus settles down. Hence, your doctor may advise you to repeat CRP after 3 days in COVID-19 if the levels in the previous CRP test were higher, to see if the infection is progressive or dwindling.

How Can I Prevent Chills


You can prevent cold chills by dressing warmly when you know youll be in the cold. Wearing layers allows you to adjust your clothes for the temperature so you dont get sweaty. Sweating and then getting cold can lower your body temperature too much.

You can also take steps to safeguard your health against medical conditions that cause chills. Avoid misusing drugs or alcohol. If you have a condition like diabetes, take care to control your blood sugar.

What Elevated Crp Levels Mean

When CRP levels remain elevated for a long time, it can indicate chronic inflammation of the blood vessels. This type of low-grade inflammation contributes to the deposit of fat and other substances in the artery walls, a condition called atherosclerosis.

This build-up can narrow the arteries that feed the heart blood, causing coronary artery disease . Over time, heart attack, stroke, or heart failure can occur. This is true even for those with elevated CRP levels who have no obvious symptoms or signs of active inflammation.

Inflammation is an important contributor to atherosclerosis and elevated CRP is associated with an increased risk of CAD. A study of 376 people found that 210 of them diagnosed with CAD all had elevated CRP levels when compared with 166 people who did not have CAD.

The CRP level increased in step with the degree of blood vessel damage evaluated by coronary angiography, an imaging test used to visualize blood flow through the heart.

What Are Periodontitis Symptoms

  • Ask you about your symptoms and medical history.
  • Examine your gums for signs of inflammation.
  • Use a special ruler to see if you have pockets around your teeth. This test won’t hurt.
  • Take an X-ray to check for bone loss, if necessary.
  • Possibly refer you to a periodontist, a specialist in gum disease.

How Is The Test Used

The C-reactive protein test is used to detect inflammation.

For example, CRP may be used to detect or monitor significant inflammation in acute conditions, such as:

  • A serious bacterial infection of the lung, urinary tract, digestive tract, skin, or other sites, with or without sepsis
  • A fungal or viral infection
  • Pelvic inflammatory disease
  • The CRP test is useful in monitoring chronic inflammatory conditions to detect flare-ups and/or to determine if treatment is effective. Some examples include:

    • Inflammatory bowel disease
    • Some forms of arthritis, including rheumatoid arthritis
    • Autoimmune diseases, such as lupus or vasculitis

    Examples of other uses:

    • The CRP test is widely used to detect sepsis in newborn babies.
    • The CRP test may be used to monitor patients after surgery. Generally, CRP levels increase after surgery and drop down to normal unless post-surgery infection is present.
    • CRP can be a good predictor of rejection in kidney transplant recipients.

    CRP may sometimes be ordered along with an erythrocyte sedimentation rate , another test that detects inflammation, or procalcitonin, a test that indicates sepsis. While the CRP test is not specific enough to diagnose a particular disease, it does serve as a general marker for infection and inflammation, thus alerting healthcare practitioners that further testing and treatment may be necessary. Depending on the suspected cause, a number of other tests may be performed to identify the source of inflammation.

    What Abnormal Results Mean

    C-Reactive Protein: Testing for Heart Disease

    It is unclear if a minor rise of 0.3 to 1 mg/dL in CRP levels is a cause for concern. The hs-CRP is more precise and may be used to further understand these results.

    • CRP levels from 1 mg/dL to 10 mg/dL are thought to be a moderate increase.
    • CRP Levels greater than 10 mg/dL are considered a marked increase.

    A positive test means you have inflammation in the body. The cause of a high CRP cannot always be determined. Some include:

    It’s A Good Predictor Of Heart Disease

    Even if heart attacks were caused by inflammation, CRP testing wouldn’t be useful unless it’s proved to be a good predictor. In other words, studies have to show that there’s a tight correlation between high C-reactive protein levels and the chances of having a heart attack.

    To make a long story short, that’s just what a series of studies published in prestigious journals has shown. One, in the Nov. 14, 2002, New England Journal of Medicine , concluded that CRP outperforms LDL cholesterol as a predictor of cardiovascular risk. In addition, the authors found that the two tests identify different high-risk groups, so using both is better than relying on either alone.

    What Does An Elevated C

    Elevation of C-reactive protein indicates acute phase response or active disease in chronic inflammatory disorders. CRP is a more sensitive early indicator of an acute phase response than the ESR . C-reactive protein also returns towards normal more rapidly with improvement or resolution of the disease process.

    C-reactive protein elevations are nonspecific and may be useful for the detection of systemic inflammatory processes to assess treatment of bacterial infections with antibiotics to detect intrauterine infections with concomitant premature rupture of membranes to differentiate between active and inactive forms of disease with concurrent infection, e.g., in patients suffering from systemic lupus erythematosus or ulcerative colitis to therapeutically monitor rheumatic disease and assess anti-inflammatory therapy to determine the presence of postoperative complications at an early stage, such as infected wounds, thrombosis, and pneumonia and to distinguish between infection and bone marrow rejection. Postoperative monitoring of CRP levels of patients can aid in the recognition of unexpected complications .

    However, the C-reactive protein test is less sensitive than the ESR for some disorders, for example, ulcerative colitis and SLE .

    Elevated of C-reactive protein test result means you have inflammation in the body. This may be due to a variety of conditions, including:

    • Rheumatic fever

    This list is not all inclusive.

    Who Should Get A Crp Test

    If your doctor suspects you might have an inflammatory disorder like arthritis, cancer, an infection, etc., they may order a C-reactive protein test. This test can show theres a high level of inflammation, but it cannot show where the inflammation is located or what might be causing it. If you have been previously diagnosed with an inflammatory issue, your doctor may also order this test occasionally to see how your treatment is working and if the issue is being properly managed.

    Its important to note that the high-sensitivity C-reactive protein test is a slightly different test than a regular C-reaction protein test. This test typically predicts heart disease and strokes. And while the regular C-reactive test can help to uncover different diseases that cause inflammation by measuring high levels of protein, the hs-CRP test measures a lower amount of protein, which can signal the risk of heart disease and stroke.

    Your doctor may order an HS-CRP if theyre focusing on cardiovascular issues.
