View larger version (27K): [in a new window]   Figure 1 Myocardial perfusion measurements examined by magnetic resonance imaging among asymptomatic subjects according to quartiles of predicted absolute 10-year risk of coronary heart disease (CHD): 1% to 4.8% (median: 3%), 4.9% to 7.9% (median: 6%), 8% to 14.9% (median: 11%), 15% to 46% (median: 20%), estimated using Framingham prediction equations with total cholesterol categories (20). The p values for trend are p = 0.004 for rest MBF, and p < 0.0001 for hyperemic MBF and PR. The error bar represented 95% confidence interval (CI).
