Table 2.
Development of cardiovascular events in 10 years after initial AF.
| Cardiovascular events | AF without comorbidities (n=173) | Typical AF (n=1031) | Matched cohort (n=1700) | |||
|---|---|---|---|---|---|---|
| Event (n) | Incidence (per 1000 person-years) | Event (n) | Incidence (per 1000 person-years) | Event (n) | Incidence (per 1000 person-years) | |
| Stroke | 10 | 6 | 60 | 9 | 85 | 4 |
| Heart failure | 33 | 21 | 245 | 42 | 189 | 9 |
| Myocardial infarction | 14 | 8 | 69 | 11 | 175 | 9 |
| All-cause mortality | 137 | 77 | 792 | 118 | 1226 | 59 |
| Total cardiovascular events* | 141 | 94 | 828 | 151 | 1253 | 65 |
Typical AFs with prevalent cardiovascular events were excluded from the analysis (e.g. total # typical AF=1664, # typical AF with prevalent events= 633). Follow-up for outcome started from AF onset date or matched cases' AF onset date for the matched cohort.
*
For each participant, only the outcome that occurred earliest was counted.
Abbreviation: AF = atrial fibrillation.
