“…Moreover, patients with new-onset AF and ECG sign of atrial infarction had a 2.43 times (95% CI 1.22 -4.84) greater 90-day mortality risk even after adjustment for other independent predictors for mortality. Further evidence of this relationship was shown in another study [24], where a significant relationship between the recurrence of AF, prolonged atrial depolarization as shown by increased P wave duration>110 ms and left atrial enlargement was found in patients with non-STEMI event. Similarly, echocardiographic indices of left atrial electromechanical dysfunction, such as prolonged total atrial activation time and increased left atrial volume, have also been shown to be independent predictors of new-onset AF in AMI patients [25].…”

“…Dilatation of LA chamber can increase the possible number of wavelet and vulnerability to fibrillation induction, irrespective of the underlying causes of LA enlargement. Accordingly, its enlargement has shown to be a strong risk factor of AF in various cardiovascular diseases including AMI [25][26][27]. Thus, AF in dilated LA could be easily triggered by small stimuli.…”

“…In a single-center report of 88 individuals with incident AF in the context of non-ST segment elevation myocardial infarction, 38% had recurrent AF at an average of 21 months of follow-up. 34 A recent study using Medicare claims data reported that AF recurred in 55% of individuals with new-onset AF in the context of sepsis at 5 years. 35 In a single-center study of 58 individuals with thyrotoxicosis-associated AF, 59% had recurrent AF at an average of 24 months of follow-up, 36 whereas a separate retrospective series of 106 patients reported that 38% had recurrent AF at almost seven years of follow-up.…”

Background Guidelines have proposed that atrial fibrillation (AF) can occur as an isolated event, particularly when precipitated by a secondary, or reversible, condition. However, knowledge of long-term AF outcomes after diagnosis during a secondary precipitant is limited. Methods and Results In 1409 Framingham Heart Study participants with new-onset AF, we examined associations between first-detected AF episodes occurring with and without a secondary precipitant, and both long-term AF recurrence and morbidity. We selected secondary precipitants based on guidelines (surgery, infection, acute myocardial infarction, thyrotoxicosis, acute alcohol consumption, acute pericardial disease, pulmonary embolism, or other acute pulmonary disease). Among 439 (31%) people with AF diagnosed during a secondary precipitant, cardiothoracic surgery (n=131, 30%), infection (n=102, 23%), non-cardiothoracic surgery (n=87, 20%), and acute myocardial infarction (n=78, 18%) were most common. AF recurred in 544 of 846 eligible individuals without permanent AF (5-, 10-, and 15-year recurrences of 42%, 56% and 62% with versus 59%, 69% and 71% without secondary precipitants; multivariable-adjusted hazard ratio [HR] 0.65, 95% confidence interval [CI] 0.54–0.78). Stroke risk (n=209/1262 at risk, HR 1.13, 95%CI 0.82–1.57) and mortality (n=1098/1409 at risk, HR 1.00, 95%CI 0.87–1.15) were similar between those with and without secondary precipitants, though heart failure risk was reduced (n=294/1107 at risk, HR 0.74, 95%CI 0.56–0.97). Conclusions AF recurs in most individuals, including those diagnosed with secondary precipitants. Long-term AF-related stroke and mortality risks were similar between individuals with and without secondary AF precipitants. Future studies may determine whether increased arrhythmia surveillance or adherence to general AF management principles in patients with reversible AF precipitants will reduce morbidity.
