Abstract Background The prognostic implication of the burden of paroxysmal new-onset atrial fibrillation (NOAF) in patients with acute myocardial infarction (AMI) remains unclear. We aimed to determine the impact of NOAF burden on long-term cardiovascular outcomes in the setting of AMI. Methods This retrospective study was conducted to investigate the association of NOAF burden with the major adverse cardiac events (MACE, a composite of cardiovascular death, recurrent MI, worsening of heart failure, or ischemic stroke), using data from the New Onset Atrial Fibrillation Complicating Acute Myocardial Infarction in ShangHai registry. AF burden was defined as the percentage of time (%) spent in AF. Patients with paroxysmal NOAF were divided into three groups according to AF burden tertiles: low burden: 22.4%. A restricted cubic spline analysis was performed to illusrate the relationship between the burden of NOAF and MACE. Results Of 2399 participants, 278 developed NOAF during a median monitoring period of 194.9 hours. The mean age was 65.8±12.4 years, and the median burden of NOAF was 8.4% (IQR: 1.9%-38.1%). During up to 5-years follow-up, the incidence of MACE was 8.6, 17.4, 35.4, and 79.2 per 100 person-years in the sinus rhythm, low-, intermediate-, and high-burden groups, respectively. After adjustment, patients with high NOAF burden had the highest risk of MACE (hazard ratio [HR]: 3.10; 95% confidence interval [CI]: 2.36–4.07), cardiovascular death (HR: 2.26; 95% CI: 1.58–2.23), worsening of heart failure (HR: 4.90; 95% CI: 3.48–4.91), and ischemic stroke (HR: 4.42; 95% CI: 2.03–9.63). Our splines analyses uncovered a nonlinear dose-response pattern, as the HRs of MACEs increased with the progression of NOAF burden and appeared stable after approximately 15% of NOAF burden. Conclusions A greater burden of NOAF during AMI was strongly associated with a higher risk of adverse cardiovascular events.

Abstract Background New-onset atrial fibrillation (NOAF) complicating acute myocardial infarction (AMI) has been associated with poor survival, but the clinical implication of NOAF on subsequent heart failure (HF) is still not well studied. We aimed to investigate the relationship between NOAF following AMI and HF hospitalization. Methods This retrospective cohort study was conducted between February 2014 and March 2018, using data from the New-Onset Atrial Fibrillation Complicating Acute Myocardial Infarction in ShangHai registry, where all participants did not have a documented AF history. Patients with AMI who discharged alive and had complete echocardiography and follow-up data were analyzed. The primary outcome was HF hospitalization, which was defined as a minimum of an overnight hospital stay of a participant who presented with symptoms and signs of HF or received intravenous diuretics. Results A total of 2075 patients were included, of whom 228 developed NOAF during the index AMI hospitalization. During up to 5 years of follow-up (median: 2.7 years), 205 patients (9.9%) experienced HF hospitalization and 220 patients (10.6%) died. The incidence rate of HF hospitalization among patients with NOAF was 18.4% per year compared with 2.8% per year for those with sinus rhythm. After adjustment for confounders, NOAF was significantly associated with HF hospitalization (hazard ratio [HR]: 3.14, 95% confidence interval [CI]: 2.30–4.28; p<0.001). Consistent result was observed after accounting for the competing risk of all-cause death (subdistribution HR: 3.06, 95% CI: 2.18–4.30; p<0.001) or performing a propensity score adjusted multivariable model (HR: 3.28, 95% CI: 2.39–4.50; p<0.001). Furthermore, the risk of HF hospitalization was significantly higher in patients with persistent NOAF (HR: 5.81; 95% CI: 3.59–9.41) compared with that in those with transient NOAF (HR: 2.61; 95% CI: 1.84–3.70; p interaction = 0.008). Conclusion NOAF complicating AMI is strongly associated with an increased long-term risk of heart.

Background: Atrial fibrillation (AF) has been identified as a major risk factor for mortality after acute coronary syndrome (ACS). However, the long-term risk of ischemic stroke associated with new-onset atrial fibrillation (NOAF) in ACS remains controversial, and its gender-specific association is unknown. Methods: We analyzed the data of 10,137 ACS survivors included in a multicenter, prospective registry for Korean patients with acute myocardial infarction (AMI) between January 2004 and August 2014. Subjects were categorized into three groups (non-AF vs. NOAF vs. previous AF) based on medical history and electrocardiographic evidence of AF, either at admission or during hospitalization. Results: Among the total study population (72.3% men), 370 patients (3.6%) had NOAF and 130 (1.3%) had previous AF. During a median follow-up of 61 months (interquartile range, 38.8 to 89.3 months), 245 (2.4%) patients (218 (2.3%) non-AF vs. 15 (4.1%) NOAF vs. 12 (9.2%) previous AF, p < 0.001) experienced ischemic stroke. After adjustment for confounding variables, both NOAF (adjusted hazard ratio (HR) 1.87, 95% confidence interval (CI) 1.09–3.24, p = 0.024) and previous AF (adjusted HR 4.00, 95% CI 2.03–7.87, p < 0.001), along with older age, diabetes, current smoker, and previous stroke were independent risk factors of ischemic stroke. In the gender-stratified analysis, men with previous AF but not NOAF had a significantly higher risk of ischemic stroke (adjusted HR 4.14, 95% CI 1.79–9.55, p = 0.001) than those without AF. In women, NOAF (adjusted HR 2.54, 95% CI 1.21–5.35, p = 0.014) as well as previous AF (adjusted HR 3.72, 95% CI 1.16–11.96, p = 0.028) was a strong predictor of ischemic stroke, and the predictive value was comparable to that of previous AF among patients with a CHA2DS2-VASc score ≥ 2. Conclusions: Both NOAF and previous AF were associated with ischemic stroke after AMI, but the impact of NOAF as a risk factor of ischemic stroke was significant only in women.

Background: The relationship between fasting hyperglycemia (FHG) and new-onset atrial fibrillation (AF) in patients with acute myocardial infarction (AMI) is unclear, and whether their co-occurrence is associated with a worse in-hospital and long-term prognosis than FHG or AF alone is unknown.Objective: To explore the correlation between FHG and new-onset AF in patients with AMI, and their impact on in-hospital and long-term all-cause mortality.Methods: We performed a retrospective cohort study comprising 563 AMI patients. The patients were divided into the FHG group and the NFHG group. The incidence of new-onset AF during hospitalization was compared between the two groups and sub-groups under different Killip grades. Logistic regression was used to assess the association between FHG and new-onset AF. In-hospital mortality and long-term all-cause mortality were compared among patients with FHG, AF, and with both FHG and AF according to 10 years of follow-up information.Results: New-onset AF occurred more frequently in the FHG group than in the NFHG group (21.6 vs. 9.2%, p &lt; 0.001). This trend was observed for Killip grade I (16.6 vs. 6.5%, p = 0.002) and Grade II (17.1 vs. 6.9%, p = 0.005), but not for Killip grade III–IV (40 vs. 33.3%, p = 0.761). Logistic regression showed FHG independently correlated with new-onset AF (OR, 2.56; 95% CI, 1.53–4.30; P &lt; 0.001), and 1 mmol/L increased in fasting glucose was associated with a 5% higher rate of new-onset AF, after adjustment for traditional AF risk factors. AMI patients complicated with both fasting hyperglycemia and AF showed the highest in-hospital mortality and long-term all-cause mortality during an average of 11.2 years of follow-up. Multivariate Cox regression showed FHG combined with AF independently correlated with long-term all-cause mortality after adjustment for other traditional risk factors (OR = 3.13, 95% CI 1.64–5.96, p = 0.001), compared with the group with neither FHG nor new-onset AF.Conclusion: FHG was an independent risk factor for new-onset AF in patients with AMI. AMI patients complicated with both FHG and new-onset AF showed worse in-hospital and long-term all-cause mortality than with FHG or AF alone.

Background: New-onset atrial fibrillation (NOAF) is a common complication during acute myocardial infarction (AMI) and sometimes can be completely asymptomatic, but the clinical implications of these asymptomatic episodes require further characterization. The objective of this study was to investigate the short- and long-term prognostic impact of post-MI NOAF based on the presence of AF-related symptoms.Methods: The New-Onset Atrial Fibrillation Complicating Acute Myocardial Infarction in ShangHai (NOAFCAMI-SH) registry was a retrospective cohort including participants with AMI without a documented history of AF. Patients with NOAF were divided into two groups according to the AF-related symptoms. The primary endpoint was all-cause mortality.Results: Of 2,399 patients included, 278 (11.6%) developed NOAF of whom 145 (6.0%) with asymptomatic episodes and 133 (5.5%) with symptomatic ones. During hospitalization, 148 patients died [106, 10, and 32 in the sinus rhythm (SR), asymptomatic, and symptomatic NOAF groups, respectively]. After multivariable adjustment, only symptomatic NOAF was associated with in-hospital mortality [odds ratio (OR): 2.32, 95% confidence interval (CI): 1.36–3.94] compared with SR. Over a median follow-up of 2.7 years, all-cause mortality was 3.2, 12.4, and 11.8% per year in the SR, asymptomatic, and symptomatic NOAF groups, respectively. After adjustment for confounders, it was the asymptomatic NOAF [hazard ratio (HR): 1.61, 95% CI: 1.09–2.37) rather than the symptomatic one (HR: 1.37, 95% CI: 0.88–2.12) that was significantly related to mortality. Similar results were also observed for cardiovascular mortality [HRs and 95% CI were 1.71 (1.10–2.67) and 1.25 (0.74–2.11) for asymptomatic and symptomatic NOAF, respectively]. Both asymptomatic and symptomatic NOAF episodes were associated with heart failure, whereas only those with symptomatic NOAF were at heightened risk of ischemic stroke. Our exploratory analysis further identified patients with asymptomatic high-burden NOAF as the highest-risk population (mortality: 19.6% per year).Conclusion: Among patients with AMI, symptomatic NOAF is related to in-hospital mortality and asymptomatic NOAF is associated with poor long-term survival.Registration: URL: https://clinicaltrials.gov/; Unique identifier: NCT03533543.

Abstract Introduction Atrial fibrillation (AF) is a frequent complication of acute myocardial infarction (AMI) and is associated with a worse prognosis. Patients with chronic kidney disease are more likely to develop AF. Whether the association between AF and renal function is also true in AMI has never been investigated. Purpose The aim of the study was to assess the incidence of new-onset AF according to renal function, estimated at hospital admission, and its relationship with short-term outcome and long-term all-cause mortality in a large real-world cohort of AMI patients. Methods We prospectively enrolled 2,445 AMI patients. New-onset AF was recorded during hospitalization. Glomerular filtration rate (eGFR) was estimated at admission and patients were grouped according to their renal function (group 1 [n=1,887]: eGFR&gt;60; group 2 [n=492]: eGFR 60–30; group 3 [n=66]: eGFR&lt;30 ml/min/1.73m2). The primary endpoint was AF incidence. In-hospital and long-term (median 5 years) all-cause mortality were the secondary endpoints. Results The AF incidence in the whole population was 10% and it was associated with a higher in-hospital (5% vs. 1%; P&lt;0.0001) and long-term mortality (34% vs. 13%; P&lt;0.0001). The AF incidence was 8%, 16%, 24% in groups 1, 2, 3, respectively (P&lt;0.0001). In each group, in-hospital mortality was higher in AF patients (3.5% vs. 0.5%, 6.5% vs. 3.0%, 19% vs. 8%, respectively; P&lt;0.0001). A similar trend was observed for long-term mortality (20% vs. 9%, 51% vs. 24%, 81% vs. 50%, respectively; P&lt;0.0001). The higher risk for in-hospital and long-term mortality associated with AF in each group was confirmed also after adjustment for major confounders. Conclusions The study demonstrates that the incidence of new-onset AF during AMI, as well as its associated in-hospital and long-term mortality, increases in parallel with the severity of renal dysfunction assessed at hospital admission.

Abstract Background Atrial fibrillation (AF) often coexists with coronary artery disease. Data on the incidence and prognostic impact of new-onset AF following acute myocardial infarction (AMI) with current optimal therapy are insufficient, especially in Asian populations. Purpose To investigate the incidence of new-onset AF following AMI and to assess its impact on in-hospital and long-term prognosis. Methods We included consecutive AMI patients between December 2012 and July 2019, and excluded those with prior known AF on presentation. New-onset AF was defined as newly detected AF during the index hospitalization following AMI. The primary outcomes comprised of all-cause death and cardiovascular death occurred during hospitalization; and all-cause death and cardiovascular death during long-term follow-up among those AMI survivors. Follow-up visits were routinely scheduled after discharge, at 1 month, 3 months, 6 months, 12 months and every 12 months thereafter. Results Of 3686 patients enrolled, new-onset AF was documented in 138 (3.7%) patients during a mean duration of hospitalization of 8.8±5.8 days. Independent risk factors of new-onset AF were age ≥75 years, left atrial diameter ≥40mm, high levels of cardiac troponin-I or high sensitive C reactive protein. During hospitalization, all-cause death occurred in 22 (15.9%) new-onset AF patients and 67 (1.9%) non-AF patients (p&lt;0.001); cardiovascular death occurred in 19 (13.8%) new-onset AF patients and 58 (1.6%) non-AF patients (p&lt;0.001). On multivariable logistic analysis, new-onset AF was an independent predictor of in-hospital all-cause death (OR 5.85, 95% CI: 3.24–10.55) and cardiovascular death (OR 5.44, 95% CI: 2.90–10.20). Apart from the in-hospital deaths, another 265 (7.7%) were lost to follow-up; thus, 3332 patients were included in the long-term follow-up analysis: 106 new-onset AF and 3226 non-AF patients. After a mean follow-up period of 1096.7±682.0 days, all-cause death occurred in 19 new-onset AF patients and 249 non-AF patients; corresponding rates were 8.08 (95% CI: 5.15–12.67) vs. 2.55 (95% CI: 2.25, 2.88) per 100 person-years, respectively (p&lt;0.001). Cardiovascular death occurred in 11 new-onset AF patients and 150 non-AF patients; corresponding rates were 4.68 (95% CI: 2.59–8.45) vs. 1.53 (95% CI: 1.31–1.80) per 100 person-years, respectively (p=0.002). After multivariable Cox adjustment, there was no significant association between new-onset AF and long-term all-cause death (HR 1.45, 95% CI: 0.90–2.35) or cardiovascular death (HR 1.21, 95% CI: 0.65–2.26). Conclusion New-onset AF following AMI was an independent predictor of increased risk of in-hospital mortality, but had no independent association with long-term death.
