Figure 1. The time course of the
functional capacity. (A) Changes in the functional capacity between
baseline and 3 months after the pacemaker implantation. Three months
after the pacemaker implantation, 43% of those with a poor and moderate
FC at baseline improved to a good FC (16+105/40+239). (B) The
distribution of the FCs at baseline, 3 months, 6-month, and 1 year after
the pacemaker implantation. The patients were a priori classified
into a poor FC (<2 METs), moderate FC (2<METs <4), and good FC (> 4 METs).
FC=functional capacity, METs=metabolic
equivalents.
Figure 2 . Kaplan-Meier analysis of the time to the subsequent
outcome.
(A ) The cardiovascular hospitalization rate was higher in the
patients with a poor FC than in those with a moderate or good FC.
(B ) The total mortality rate was higher in the patients with a
poor FC than in those with a moderate FC or good FC. FC=functional
capacity.
Figure 3 . Subgroup analysis among the patients with a poor
functional capacity.
(A ) Changes in the functional capacity during a 1-year
follow-up. Seven (1.75%) patients improved to a moderate FC, and 19
(47.5%) had a marked improvement. FC=functional capacity, F/U=follow
up.
(B ) The total mortality rate. A log-rank test was not applied
because no patients with a good FC died.
