According to the American Heart Association, results of the hs-CRP in determining the risk for heart disease can be interpreted as follows:

You are at low risk of developing cardiovascular disease if your hs-CRP level is lower than 1.0 mg/L.

You are at average risk of developing cardiovascular disease if your levels are between 1.0 mg/L and 3.0 mg/L.

You are at high risk for cardiovascular disease if your hs-CRP level is higher than 3.0 mg/L.

so you are at average risks for developing cardiovascular disease.

do you smoke or are you overweight? these can increase your risks for cardiovascular disease.
