To calculate your cholesterol ratio, divide your high-density lipoprotein (HDL, or good) cholesterol number into your total cholesterol number. An optimal ratio is less than 3.5-to-1. A higher ratio means a higher risk of heart disease.
A blood test called the high sensitivity C-reactive protein blood test (hs-CRP) is now widely available. Most studies show that in healthy people, the higher the hs-CRP levels, the higher the risk of developing a future heart attack. In fact, scientific studies have found that the risk for heart attack in people in the upper third of hs-CRP levels is twice that of those with hs-CRP levels in the lower third. Recent studies also found a link between hs-CRP, sudden cardiac death and peripheral arterial disease.
