Abstract Funding Acknowledgements Type of funding sources: None. Background New-onset atrial fibrillation (NOAF) is a significant complication of acute myocardial infarction (AMI) associated with a poor prognosis. The knowledge and understanding of risk factors of this arrhythmia are still the subjects of interest. Purpose: We aimed to investigate which clinical, routinely checked parameters could have the most predictive power on NOAF occurrence in AMI patients. Patients and methods This single-center, retrospective study was conducted on 954 consecutive patients admitted to our university clinical center with AMI diagnosis from January 2017 to December 2018. Patients underwent routine clinical assessment and laboratory investigations. AF detected at the time of admission or during a hospital stay, without a prior history of persistent or paroxysmal AF, was diagnosed as NOAF. Detailed medical history, routinely checked laboratory and echocardiography parameters, invasive and pharmacological treatment, as well as complications and in-hospital mortality, were taken into consideration. Results   NOAF was documented in 106 (11%) AMI patients at median age 74 (66 - 84) years old, and was significantly associated with in-hospital mortality [OR 4.53, p < 0.001). There were some clinical factors significantly predicted NOAF in univariate logistic regression analysis: age ≥ 66 years old (odds ratio [OR] 3.09, p < 0.001), B-type natriuretic peptide (BNP) ≥ 340 pg/ml (OR 5.28, p < 0.001), C- reactive protein (CRP) ≥ 7.7 mg/l (OR 3.53, p < 0.001), high-sensitivity troponin ≥ 1.85 ng/ml (OR 2.4, p < 0.001), total cholesterol  ≤  195 mg/dl (OR 2.17, p < 0.002), low-density lipoprotein ≤ 128.5 mg/dl (OR 2.03, p < 0.007), potassium level ≤ 4.2 mmol/l (OR 1.92, p < 0.002), hemoglobin ≤ 14 g/dl (OR 1.71, p < 0.020), leucocytes ≥ 10.2 x10^9/l (OR 1.76, p < 0.009), neutrophil to lymphocyte ratio ≥ 4.6 (OR 1.85, p < 0.004), left atrium size ≥ 41 mm (OR 2.14, p < 0.001), and left ventricular ejection fraction (LVEF) ≤ 44% (OR 2.99, p < 0.001). Age, BNP, CRP, and LVEF at mentioned above pre-specified cut-off values turned out to be the most important independent predictors of NOAF development in multivariate analysis. Conclusions NOAF is a multifactorial, significant complication of AMI, leading to a worse prognosis. Older age, higher BNP and CRP level, and lower LVEF are independently associated with the probability of NOAF.

(1) Background: New-onset atrial fibrillation (NOAF) is a significant complication of acute myocardial infarction (AMI). Our study aimed to investigate whether routinely checked clinical parameters aid in NOAF identification in modernly treated AMI patients. (2) Patients and methods: Patients admitted consecutively within 2017 and 2018 to the University Clinical Centre in Gdańsk (Poland) with AMI diagnosis (necrosis evidence in a clinical setting consistent with acute myocardial ischemia) were enrolled. Medical history and clinical parameters were checked during NOAF prediction. (3) Results: NOAF was diagnosed in 106 (11%) of 954 patients and was significantly associated with in-hospital mortality (OR 4.54, 95% CI 2.50–8.33, p < 0.001). Age, B-type natriuretic peptide (BNP), C-reactive protein (CRP), high-sensitivity troponin I, total cholesterol, low-density lipoprotein cholesterol, potassium, hemoglobin, leucocytes, neutrophil/lymphocyte ratio, left atrium size, and left ventricular ejection fraction (LVEF) were associated with NOAF in the univariate logistic analysis, whereas age ≥ 66 yo, BNP ≥ 340 pg/mL, CRP ≥ 7.7 mg/L, and LVEF ≤ 44% were associated with NOAF in the multivariate analysis. (4) Conclusions: NOAF is a multifactorial, significant complication of AMI, leading to a worse prognosis. Simple, routinely checked clinical parameters could be helpful indices of this arrhythmia in current invasively treated patients with AMI.

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.

New-onset atrial fibrillation (NOAF) during acute myocardial infarction (AMI) has significant consequences but is often misdiagnosed. The aim of the study was to evaluate predictors of NOAF throughout different phases of AMI. Patients with AMI admitted to a tertiary medical center were analyzed. Exclusion criteria were preexisting AF, AMI onset ≥24 hours prior to admission, in-hospital death, significant valvular disease, and in-hospital coronary artery bypass graft. Study population were AMI without-NOAF, early-AF (AF terminated within 24 hours of admission), and late-AF (beyond the first 24 hours). Overall 5946 patients were included, age: 64.8 ±14.8 years; 30% women. The incidence of NOAF was 4.6%: 1.6% early-AF, and 3% late-AF. Patients with NOAF comprised greater rate of women, cardiovascular risk-factors burden, severe left ventricular-dysfunction, pulmonary hypertension, valvular disorders, and left atrial enlargement compared with patients without-NOAF. Non-ST-elevation myocardial infarction and inferior-ST-elevation myocardial infarction (STEMI) were significantly more prevalent among early-AF group, while anterior-STEMI, in late-AF. The final multivariate models showed c-statistics of 0.73 and 0.76 for the prediction of new-onset early-AF and late-AF, respectively. In conclusion, there are different clinical predictors of early- versus late-NOAF. The study points out “high risk” AMI population for more meticulous heart rate monitoring for NOAF.

Abstract Background New-onset atrial fibrillation (NOAF) is common during acute myocardial infarction (AMI) and independently associated with worse prognosis. We aimed to validate the discrimination performance of CHA2DS2-VASc score combined with hs-CRP in the prediction of NOAF after AMI in elderly Chinese population. Methods 311 consecutive elderly patients (age ≥ 65 years old) with AMI from 1 January 2018 to 1 January 2019 without atrial fibrillation history were enrolled in our study. Univariable and multivariable logistic regression analyses were used to identify risk factors of NOAF. The discrimination performance of different score models were evaluated using ROC curve analysis and AUCs were compared using the Z test. Results 30 (9.65%) patients developed NOAF during hospitalization. The NOAF group were older and had higher hs-CRP, initial Killip class, BNP, LAD, CHADS2 score, CHA2DS2-VASc score, in-hospital mortality and lower LVEF and ACEI/ARB use (P < 0.05 vs group without NOAF for all measures). In multivariate regression analyses, age (OR = 1.127, 95% CI 1.063–1.196, P < 0.001) and hs-CRP (OR = 1.034, 95% CI 1.018–1.05, P < 0.001) were independent predictors of NOAF. In ROC curve analyses, both CHADS2 score (AUC = 0.624, 95% CI 0.516–0.733, P = 0.026) and CHA2DS2-VASc score (AUC = 0.687, 95% CI 0.584–0.79, P = 0.001) had acceptable but unsatisfactory discrimination performance in predicting NOAF after AMI. The combined model with CHA2DS2-VASc score and hs-CRP showed a significant better predictive value (AUC = 0.791, 95% CI 0.692–0.891, P < 0.001) compared to that of the CHA2DS2-VASc score alone (Z test, P = 0.008). Conclusion The combined model with CHA2DS2-VASc score and hs-CRP had high accuracy in predicting post-AMI NOAF.

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&lt;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&lt;0.001) or performing a propensity score adjusted multivariable model (HR: 3.28, 95% CI: 2.39–4.50; p&lt;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.
