Evaluation of the Effect of Concurrent Chronic Total Occlusion and Successful Staged Revascularization on Long-Term Mortality in Patients with ST-Elevation Myocardial Infarction

Figure 1

Time-to-event curves for mortality 0 to 30 days (a), mortality 30 days–3 years (b), and overall 3-year mortality (c) in patients with SVD, MVD without a CTO, and MVD with a CTO in a non-IRA. 𝑃 values shown in figure are three-way. Pair-wise 𝑃 values for 30-day mortality are CTO versus SVD, 𝑃<0.001; MVD without a CTO versus SVD, 𝑃=0.040; CTO versus MVD without a CTO, 𝑃=0.035. Pair-wise 𝑃 values for mortality between 30 days and 3 years are CTO versus SVD, 𝑃<0.001; MVD without a CTO versus SVD, 𝑃=0.043; CTO versus MVD without a CTO, 𝑃=0.011. Pair-wise 𝑃 values for overall 3-year mortality are CTO versus SVD, 𝑃<0.001; MVD without a CTO versus SVD, 𝑃=0.005; CTO versus MVD without a CTO, 𝑃=0.001.
