Some studies have shown a correlation between elevated CRP and an increased risk of developing heart disease because CRP may be elevated by inflammation in the blood vessels. A newer test, called the highly sensitive CRP, may be more accurate than the regular CRP for determining heart disease risk.
That said, CRP is not specific to blood vessel inflammation and may be elevated by inflammation anywhere in the body. Even a cold can cause a temporary increase in the CRP level. But that doesn't mean you will get heart disease from the elevation of CRP from a cold - it just means that the cold has triggered an inflammatory response in the body to deal with the cold. Likewise, Lyme disease (or a herx) may trigger elevations in CRP that may or may not have anything to do with heart disease risk because Lyme disease has a tendency to trigger inflammation in the body.
I hope this helps - take care,
