Impacts of peri-procedural DHF on long-term rhythm and cardiac
outcomes.
During the 2-year study period, 277 (28%) cases developed AF
recurrence. Freedom from AF recurrence was similar between patients with
and without DHF (hazard ratio 1.2, 95% confidence interval 0.7–2.3, p
= 0.50).
Seventeen (2%) cases developed late phase DHF requiring
re-hospitalization during the 2-year study period. Freedom from late
phase DHF requiring re-hospitalization was significantly lower in
patients with DHF than those without DHF (hazard ratio 11, 95%
confidence interval 3.6–34, p < 0.01) (Figure 4).
