Heart Failure Duration Combined with Left Atrial Dimension Predicts Super-Response and Long-Term Prognosis in Patients with Cardiac Resynchronization Therapy Implantation
Figure 2
Four Kaplan-Meier curves (response category, LAD, HF duration, and combination of HF duration and LAD) of cumulative incidence of all-cause death or hospitalization for heart failure. (a) For the combined end point, super-responders (green line) performed the best compared to non-super-responders (blue line). (b) For the combined end point, LAD ≤ 42mm group (green line) performed the best compared to LAD > 42mm group (blue line). (c) For the combined end point, there was no difference between HF duration ≤ 36 months group and HF duration > 36 months group. (d) For the combined end point, combination of HF duration ≤ 48 months and LAD ≤ 42mm group (green line) performed the best compared to others (blue line). HF: heart failure; LAD: left atrial dimension.
