Figure 4. Determinants of Response of Right Ventricular Stroke Work Index to Therapy.

Figure 4

Change in RVSWI after therapy is strongly influenced by change in cardiac output with less contribution from change in mean pulmonary artery pressure (A, B). Improvement in cardiac output after therapy is due to change in stroke volume with no influence from change in heart rate (C, D). Solid line represents best-fit line; dashed lines are 95% confidence interval.
