DHF and 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 a DHF than
in those without. Past history of hospitalization due to DHF predicts
cardiovascular death and re-hospitalization due to DHF. Once symptomatic
heart failure occurs, the stage of heart failure and underlying
structural heart diseases has already progressed.4Diuretics and inotropic agents often used for management of DHF can
cause renal impairment and myocardial toxicity, and might lead to late
phase DHF requiring re-hospitalization in the long
term.19,20 Careful treatment, lifestyle management,
and close followup of chronic heart failure will be needed in patients
with DHF after ablation.
