Figure 1 Myocardial blood flow (MBF) at rest and during adenosine hyperemia is plotted for women vs. men. Both groups show a significant rise in MBF during hyperemia, whereas values for women are significantly higher both at rest and during adenosine stress.

Figure 2 Correlations between stress myocardial blood flow (MBF) and lipid parameters HDL, triglycerides, and cholesterol/HDL ratio are plotted. Correlation coefficients and p values are as shown. To convert lipid values to millimoles per liter, multiply by 0.02586.

Figure 3 Correlations between myocardial blood flow (MBF) at rest and during stress and respective heart rate (HR) and pressure rate product (PRP) are shown. Stress correlations are depicted by closed triangles for men and open triangles for women. Resting correlations are depicted by closed circles for men and open circles for women. Correlation coefficients, p values, and equations for each correlation are as shown.
