Circadian variation of myocardial infarct size when corrected for area at risk: Peak CK was divided by area at risk measured by angiography (a) and MRI (b). Lines represent the fitted sinusoidal curves. CK/AAR(angio)=99.95+22.16 × sin (2π x (onset hour-18.22)/24) (a) and CK/AAR(MRI)=73.2+16.64 × sin (2π x (onset hour-17.28)/24) (b). Amplitude of the fitted curves are significantly different from 0 (p<0.001(a) and p<0.02(b) confirming Circadian influence on myocardial infarct size when corrected for area at risk.
