Left Ventricular Ejection Fraction Change Following Percutaneous Coronary Intervention: Correlates and Association With Prognosis

Figures

• 

  Figure 1. Change in the left ventricular ejection fraction (ΔLVEF) from baseline to 6‐ to 8‐month angiography according to categories of baseline LVEF. Data are median with 25th to 75th percentiles. LVEF indicates left ventricular ejection fraction.

• 

  Figure 2. Kaplan–Meier curves of all‐cause death according to categories of baseline LVEF. The time point 0 in the time scale represents the time of 6–8 months angiography. HR indicates hazard ratio; and LVEF, left ventricular ejection fraction

• 

  Figure 3. Kaplan–Meier curves of cardiac death according to categories of baseline LVEF. The time point 0 in the time scale represents the time of 6‐ to 8‐month angiography. HR indicates hazard ratio; and LVEF, left ventricular ejection fraction.

  Figure 4. Restricted cubic spline regression showing the association between ΔLVEF following PCI and all‐cause death. Spline curve shows the risk of mortality for ΔLVEF values between −40.0% and 40.0%. For ΔLVEF values less than −9.0%, the risk for 5‐year death was significant. The inserted table on the right side shows the HRs with 95% (CIs) for all‐cause death at different values of ΔLVEF. HR indicates hazard ratio; ΔLVEF, left ventricular ejection fraction change; and PCI, percutaneous coronary intervention.

  Figure 5. Restricted cubic spline regression showing the association between lΔLVEF following PCI and cardiac death. Spline curve shows the risk of cardiac mortality for ΔLVEF values between −40.0% and 40.0%. For ΔLVEF values <−9.5%, the risk for 5‐year cardiac death was significant. The inserted table on the right side shows the HRs with 95% CIs for cardiac death at different values of ΔLVEF. HR indicates hazard ratio; ΔLVEF, left ventricular ejection fraction change; and PCI, percutaneous coronary intervention.
