Implication
CHF incidence and mortality in AF unchanged over two decades; leaves open whether targeted strategies can alter outcomes.
Structured PICO
Has the incidence of and survival following congestive heart failure changed over time in patients with atrial fibrillation?
P
Population
3,288 residents of Olmsted County, Minnesota diagnosed with first atrial fibrillation (AF) during 1980-2000, without congestive heart failure (CHF) prior to or at AF diagnosis, mean age 71+/-15 years.
O
Outcome
Incidence of congestive heart failure (CHF) and survival following CHF over timehard clinical
Over a two-decade period, there was no significant reduction in the incidence or mortality risk of congestive heart failure following a first diagnosis of atrial fibrillation.
