The treatment of an elevated CRP in the context of cardiovascular disease, in and of itself, may be meaningless. Instead, appropriate treatment and prevention of the underlying risks and conditions need to be the primary focus of cardiovascular risk reduction.
The most effective and reliable ways to reduce many cardiac factors are regular exercise, balanced diet, and cigarette smoking cessation. In individuals with elevated cholesterol levels who do not reach their target cholesterol level with diet modification and proper exercise, cholesterol lowering medication may be advised by their treating physicians. Statin drugs (simvastatin [Zocor], atorvastatin [Lipitor], etc.) are in the forefront of the recommended cholesterol lowering agents. Lowering of CRP may be seen with the use of statin drugs even without significant improvement of the cholesterol profile.
What is C-reactive protein (CRP)?
C-reactive protein (CRP) is a blood test marker for inflammation in the body.
CRP is produced in the liver and its level is measured by testing the blood.
CRP is classified as an acute phase reactant, which means that its levels
will rise in response to inflammation. Other common acute phase reactants
include the erythrocyte sedimentation rate (ESR) and
blood platelet count.
What are the main causes of an elevated C-reactive protein?
In general, the main causes of increased CRP and other markers of
inflammation are:
Is there a link between C-reactive protein (CRP) and cardiovascular disease risk?
The elevation of CRP has also been recently linked to atherosclerosis and
heart disease. Atherosclerosis, or cholesterol plaquing of the arteries, is
known to have an inflammatory component that is thought to cause the rise in CRP
levels in the blood. Atherosclerosis is also felt to be affected by age and
other cardiovascular risk factors including
diabetes mellitus,
high cholesterol,
high blood pressure, and
cigarette smoking.
In atherosclerosis, the blood vessel wall becomes injured. This injury acts
as focus of inflammation and leads to the formation of plaques in the blood
vessel walls. The plaques typically contain blood cells of inflammation,
cholesterol deposits, and debris from the injured cells in the blood vessel
lining. The accumulation of these elements leads to narrowing of the wall of the
blood vessel. The blood vessel narrowing can hinder the blood flow and the
plaque can rupture and flake off of the blood vessel wall causing blockage and
leading to strokes and
heart attacks.
The burden of plaques in the body can be proportional to the degree of CRP
elevation in persons with atherosclerosis. Atherosclerotic plaques can exist in
different stages throughout the body.
Sjögren's syndrome is an autoimmune disease involving the abnormal production of extra antibodies that attack the glands and connective tissue. Sjögren's syndrome with gland inflammation (resulting dry eyes and mouth, etc.) that is not associated with another connective tissue disease is referred to as primary Sjögren's syndrome. Sjögren's syndrome that is also associated with a connective tissue disease, such as rheumatoid arthritis, systemic lupus erythematosus, or scleroderma, is referred to as secondary Sjögren's syndrome. Though there is no cure for Sjögren's syndrome, the symptoms may be treated by using lubricating eye ointments, drinking plenty of water, humidifying the air, and using glycerin swabs. Medications are also available to treat dry eye and dry mouth.
A stroke results from impaired oxygen delivery to brain cells via the bloodstream. A stroke is also referred to as a CVA, or cerebrovascular incident. Symptoms of stroke include: sudden numbness or weakness of the face, arm or leg. Sudden confusion, trouble speaking or understanding. Sudden trouble seeing in one or both eyes, sudden trouble walking, dizziness, or loss of balance, and/or sudden severe headache with no known cause. A TIA, or transient ischemic attack is a short-lived temporary impairment of the brain caused by loss of blood supply. Stroke is a medical emergency.
Heart attack happens when a blood clot completely obstructs a coronary
artery supplying blood to the heart muscle. A heart attack can cause chest pain, heart failure, and electrical
instability of the heart.
Peripheral vascular disease (PVD) refers to diseases of the blood vessels (arteries and veins) located outside the heart and brain. While there are many causes of peripheral vascular disease, doctors commonly use the term peripheral vascular disease to refer to peripheral artery disease (peripheral arterial disease, PAD), a condition that develops when the arteries that supply blood to the internal organs, arms, and legs become completely or partially blocked as a result of atherosclerosis. Peripheral artery disease symptoms include: intermittent claudication, rest pain, numbness in the extremities, and more. Treatment for peripheral artery disease include: lifestyle measures, medication, angioplasty, and surgery.
Osteomyelitis is an infection of the bone. Potential causes include injections around the bone, fractures that puncture the skin, recent surgeries, and bacterial infections that travel from other areas of the body, spreading through the blood to the bone. Symptoms include pain, fever, chills, stiffness, and nausea. Treatment involves antibiotics and pain medications. Surgery is sometimes necessary.
Smoking is an addiction. More than 430,000 deaths occur each year in the U.S. from smoking related illnesses. Secondhand smoke or "passive smoke" also harm family members, coworkers, and others around smokers. There are a number of techniques available to assist people who want to quit smoking.
Wegener's granulomatosis, a condition that usually affects young or middle-aged adults, is an inflammation of the arteries supplying blood to the sinuses, lungs, and kidneys. Symptoms of Wegener's granulomatosis include bloody sputum, fatigue, weight loss, joint pain, sinusitis, shortness of breath, and fever. Wegener's granulomatosis may be fatal within months without treatment. Treatment aims to stop inflammation with high doses of prednisone and cyclophosphamide.
Rheumatic fever is a disease that sometimes occurs after a group A streptococcal infection of the throat. Symptoms and signs include carditis, polyarthritis, Aschoff bodies, rash, Sydenham's chorea, and fever. Treatment for rheumatic fever involves eliminating the bacteria with penicillin, erythromycin, or azithromycin. Further treatment focuses on alleviating the symptoms brought on by the body's immunologic response to the bacteria.
Septic arthritis, or infectious arthritis, is infection of one or more joints by bacteria, viruses, or fungi. Symptoms and signs of septic arthritis include fever, joint pain, chills, swelling, redness, warmth, and stiffness. Treatment involves antibiotics and the drainage of the infected joint.
Relapsing polychondritis is an uncommon, chronic disorder of the cartilage that is characterized by recurrent episodes of inflammation of the cartilage of various tissues of the body. Tissues containing cartilage that can become inflamed include the ears, nose, joints, spine, and windpipe (trachea). Tissues that have a biochemical makeup similar to that of cartilage such as the eyes, heart, and blood vessels, can also be affected. Nonsteroidal antiinflammatory medications (NSAIDs) is used as treatment for mild cases of the disease. Steroid-related medications also are usually required.
Regular physical activity can reduce the risk of disease. Regular exercise can also reduce the symptoms of stress and anxiety. There are fitness programs that fit any age or lifestyle.
Heart attacks are the major causes of unexpected, sudden death among men and women. A heart attack is also a significant cause of heart failure. Learn the risk factors for heart attack such as high blood pressure, diabetes, and other heart conditions. Lowering your risk factor, lifestyle changes, and in some cases medication are the most effective way of preventing a heart attack.
The heart is a very important organ in the body. It is responsible for continuously pumping oxygen and nutrient-rich blood throughout your body to sustain life. It is a fist-sized muscle that beats (expands and contracts) 100,000 times per day, pumping a total of five or six quarts of blood each minute, or about 2,000 gallons per day.
Balloon angioplasty of the coronary artery, or percutaneous transluminal coronary angioplasty (PTCA), was introduced in the late 1970's. PTCA is a non-surgical procedure that relieves narrowing and obstruction of the arteries to the muscle of the heart (coronary arteries). This allows more blood and oxygen to be delivered to the heart muscle.
PTCA, is now referred to as percutaneous coronary intervention, or PCI, as this
term includes the use of balloons, stents, and atherectomy devices. Percutaneous
coronary intervention is accomplished with a small balloon catheter inserted into an artery in the groin or arm, and advanced to the narrowing in the coronary artery. The balloon is then inflated to enlarge the narrowing in the artery. When successful,
percutaneous coronary intervention can relieve chest pain of angina, improve the prognosis of
individuals with unstable angina, and minimize or stop a heart attack without having the patien...
