- HIGH SENSITIVITY C-REACTIVE PROTEIN (HS-CRP)
C-reactive protein (CRP) is a protein that increases in the blood with inflammation and infection as well as following a heart attack, surgery, or trauma. Studies have suggested that a persistent low level of inflammation plays a major role in atherosclerosis, the narrowing of blood vessels due to build-up of cholesterol and other lipids, which is often associated with cardiovascular disease (CVD). The hs-CRP test accurately measures low levels of CRP to identify low but persistent levels of inflammation and thus helps predict a person’s risk of developing cardiovascular disease.
There are two different tests that measure CRP and each test measures a different range of CRP level in the blood for different purposes:
- The standard CRP test measures markedly high levels of the protein to detect diseases that cause significant inflammation. It measures CRP in the range from 10 to 1000 mg/L. This test may be used to detect inflammation.
- The hs-CRP test accurately detects lower levels of the protein than the standard CRP test. It measures CRP in the range from 0.5 to 10 mg/L. This test is used to evaluate individuals for risk of cardiovascular disease.
High-sensitivity CRP is one of a growing number of cardiac risk markers that are used to help determine a person’s risk. Some studies have shown that measuring CRP with a highly sensitive assay can help identify the risk level for cardiovascular disease in apparently healthy people. This more sensitive test can measure CRP levels that are within the higher end of the reference range. These normal but slightly high levels of CRP in otherwise healthy individuals can predict the future risk of a heart attack, stroke, sudden cardiac death, and peripheral arterial disease, even when cholesterol levels are within an acceptable range.
hs-CRP could be a marker not only in apparently healthy people, recent studies have shown. Adults with congenital heart disease (ACHD) with elevated CRP have worse functional status and exercise capacity, greater risk for death, or non-elective cardiovascular hospitalization.
How is the test used?
A high-sensitivity C-reactive protein (hs-CRP) test measures low levels of CRP and may be used to help evaluate an individual for risk of cardiovascular disease (CVD). It may be used in combination with a lipid panel or with other cardiac risk markers, such as a lipoprotein-associated phospholipase A2 (Lp-PLA2) test, to provide added information about heart disease risk.
High-sensitivity CRP is thought by some experts to be a useful test for determining risk of cardiovascular disease, heart attacks, and strokes and that hs-CRP can play a role in the evaluation process before a person develops one of these health problems. Some say that the best way to predict risk is to combine a good marker for inflammation, like hs-CRP, with the lipid panel. Several groups have recommended that this test be used for people who have a moderate risk of heart attack over the next 10 years.
However, not all health professionals agree on hs-CRP’s usefulness. Clinical trials that involve measuring hs-CRP levels are currently underway in an effort to better understand its role in cardiovascular events. These studies will help to form and refine guidelines on its use in screening and treatment decisions.
When is it ordered?
Currently, there is no consensus on when to get tested, though some guidelines include recommendations on hs-CRP testing. For example, a guideline from the American College of Cardiology Foundations and the American Heart Association says that hs-CRP testing may be useful when men 50 years old or younger and women 60 years old or younger have intermediate risk. It also may be useful for treatment decisions when men and women are older than these respective ages and have LDL-C less than 130 mg/L and meet several other criteria, such as no existing heart disease, diabetes, kidney disease, or inflammatory conditions.
When hs-CRP is evaluated, it may be repeated to confirm that a person has persistent low levels of inflammation.
What does the test result mean?
Relatively high levels of hs-CRP in otherwise healthy individuals have been found to be predictive of an increased risk of a future heart attack, stroke, sudden cardiac death, and/or peripheral arterial disease, even when cholesterol levels are within an acceptable range.
People with higher hs-CRP values have the highest risk of cardiovascular disease and those with lower values have less risk. Specifically, individuals who have hs-CRP results at the high end of the normal range have 1.5 to 4 times the risk of having a heart attack as those with hs-CRP values at the low end of the normal range.
Here are what the results mean:
- hs-CRP level of lower than 1.0 mg/L -- low risk of cardiovascular disease
- hs-CRP level of 1.0 mg/L and 3.0 mg/L -- moderate risk of cardiovascular disease
- hs-CRP level of more than 3.0 mg/L -- high risk of cardiovascular disease
These values are only a part of the total evaluation process for cardiovascular diseases. Additional risk factors to be considered are elevated levels of cholesterol, LDL-C, triglycerides, and glucose. In addition, smoking, high blood pressure (hypertension), and diabetes also increase the risk level.
