Using Data

Introduction: Atrial Fibrillation (AF) is a common complication during hospitalization for acute myocardial infarction (AMI) and is associated with increased morbidity and mortality in patients with AMI.However, there is limited information on contemporary trends in the incidence of AF in patients admitted with AMI and its impact on clinically relevant in-hospital and post-discharge outcomes. Methods: We examined trends in AF complicating AMI using data from the Worcester Heart Attack Study. The study population consisted of 6384 residents of Worcester, Massachusetts hospitalized with AMI for 7 biennial years from 1999 to 2011. Data was abstracted through the review of hospital medical records. Multivariate logistic regression analysis was used to examine the association between occurrence of AF and various in-hospital complications. Results: Overall incidence of AF complicating AMI was 10.8 %. The rate increased in the first half of the study period from 1999 to 2003 and declined thereafter .In models adjusting for other factors associated with adverse outcomes following AMI, we noted that compared to patients who did not develop AF, those who developed AF following AMI were at a higher risk of developing stroke [OR 2.53, 95 % CI 1.56 to 4.13], heart failure [OR 1.56, 95 % CI 1.31 to 1.87], and cardiogenic shock [OR 3.72, 95 % CI 2.82 to 4.90]. All-cause mortality during hospitalization was higher in those who developed AF[ OR 2.34, 95 % CI 1.87 to 2.94 ]; as was 30 day post discharge mortality [OR 1.29, 95 % CI 0.90 to 1.86] and 30 day post discharge readmission rate [OR 1.37, 95 % CI 1.09 to 1.72]. Conclusion: Our findings show that despite advancements in the treatment of AMI and reduced in-hospital mortality over the last 2 decades, new-onset AF remains common and related to multiple in-hospital and post-discharge adverse outcomes. Increased in-hospital monitoring and short-term post-discharge surveillance appears warranted for patients who develop AF in the context of AMI.

Background: Triple therapy is the combination of dual antiplatelet therapy plus oral anticoagulant after stent implantation. Current guidelines recommend triple therapy for acute coronary syndrome with atrial fibrillation (AF). This study aimed to identify temporal trends of antithrombotic therapy in patients with acute myocardial infarction (AMI) and AF.Methods: Among 13,104 consecutive patients from the Korea Acute Myocardial Infarction Registry-National Institute of Health (KAMIR-NIH) registry, we identified 453 patients with AF after stent implantation for AMI; these patients were then divided into those who did and did not use oral anticoagulant (OAC) [OAC group (n = 71) vs. non-OAC group (n = 382), respectively].Results: The results showed that the prevalence of AF in AMI patients was 5.4% (712/13,104). Among 453 patients, only 15.7% (71/453) were treated with OAC while dual or single antiplatelet therapy was provided for 84.7% (382/453) of patients. In patients with high stroke risk (CHA2DS2-VASc score ≥ 2), OACs were used only in 17% (69/406). Multivariate analysis revealed that female sex [odds ratio (OR) 2.11; 95% CI: 1.17–3.79], diabetes mellitus (DM) (OR 2.37; 95% CI: 1.35–4.17), prior cerebrovascular accident (CVA) (OR 4.19; 95% CI: 2–8.75), and congestive heart failure (CHF) (OR 1.89; 95% CI: 1.09–3.3) as the significant determinants of OAC use.Conclusion: The study concluded that OAC was underused. Approximately, 15%, of AMI patients with AF undergoing PCI with stent and female gender, DM, prior CVA history, and a history of CHF or the presence of moderate to severe left ventricle systolic impairment were significant determinants of OAC use.

ObjectiveTo investigate the long-term prognostic implications of transient new-onset atrial fibrillation (AF) in patients with acute myocardial infarction (AMI).DesignRetrospective observational study.SettingSingle tertiary centre.ParticipantsThis study included 2523 patients who presented with AMI from 3 June 2003 to 24 February 2015, after the exclusion of those with prior AF or in-hospital death.Outcome measuresPatients were divided into three groups according to the occurrence and type of new-onset AF: (1) sinus rhythm (SR) group; (2) paroxysmal AF (PaAF: AF converted to SR prior to discharge) group and (3) persistent AF (PeAF: AF persisted during the hospitalisation) group. Post-discharge all-cause mortality and stroke incidences were compared between the groups.ResultsNew-onset AF was observed in 271 patients (10.7%; PaAF: 230, PeAF: 41). The median follow-up period was 7.2 years (IQR: 5.2–9.4). The incidence of all-cause death and stroke was highest in the PeAF group, followed by the PaAF and SR groups (all-cause mortality: 48.8% vs 26.5% vs 14.7%, p<0.001; stroke 22.0% vs 8.3% vs 4.4%, p<0.001). In the multivariable analysis, PaAF and PeAF were associated with an increased risk of stroke (PaAF, HR: 1.972, 95% CI: 1.162–3.346; PeAF, HR: 5.160, CI: 2.242–11.873) compared with SR. The PaAF group showed a higher incidence of post-discharge AF than the SR group (29.1% vs 4.2%, p<0.001).ConclusionsNew-onset AF following AMI is associated with poor long-term outcomes. Even when AF episodes are brief and are converted to SR, new-onset AF remains associated with an increased risk of recurrent AF and stroke.

Abstract Background The quality of care among young adults with acute myocardial infarction (AMI) may be related to biological sex, psycho-socio-cultural (gender) determinants or healthcare system-level factors. Purpose To examine whether sex, gender, and the type of healthcare system influence the quality of AMI care among young adults. Methods A total of 4,564 AMI young adults (&lt;55 years) (59% women, 47 years, 66% US) were analyzed from the VIRGO and GENESIS-PRAXY studies consisting of single-payer (Canada, Spain) versus multipayer (US) systems. For each patient treated in each system we calculated a quality of care score (QCS) for pre-AMI (1-year pre admission), in-hospital, and post-AMI (1-year post discharge) phases of care (number of quality indicators received divided by the total number [range=0–100%], with higher scores indicating better quality). Ordinal logistic or linear regression models, and 2-way interactions between sex, gender and healthcare system were tested. Results Women in the multipayer system had the highest risk factor burden. Across the phases of care for AMI, 20% of quality indicators were missed in both sexes. High stress, earner status, and social support were associated with a higher QCS in the pre-AMI phase, whereas only employment and earner status were associated with QCS in all other phases. In the pre-AMI phase, women had higher QCS than men, mainly in the single-payer system (adjusted-OR=1.85, 95% CI 1.46,2.35 vs. 1.07, 95% CI 0.84,1.36, P-interaction= 0.002). Regardless of sex, only employment status had a greater effect in the multipayer system (adjusted-OR=0.59, 95% CI 0.44,0.78 vs 1.13, 95% CI 0.89,1.44, P-interaction &lt;0.001). In the in-hospital phase, women had a lower QCS than men, especially in the multipayer system (adjusted-mean-difference: −2.48, 95% CI-3.87, −1.08). Employment was associated with a higher QCS (2.0, 95% CI 0.9–3.17, P-interaction &gt;0.05). Finally, in the post-AMI phase, men and women had a lower QCS, predominantly in the multipayer system. However, primary earners had higher QCS regardless of system. Conclusion Sex, gender, and healthcare system affected the quality of care after AMI. Women had a poorer in-hospital than men and both women and men had suboptimal post-discharge care. Being unemployed lowered the quality of care, more so in the multipayer system.

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 It is unclear whether catheter ablation is beneficial in frail patients with AF. Purpose This study aimed to evaluate whether catheter ablation reduces death and other outcomes in real-world frail patients with atrial fibrillation (AF). Methods Out of 801,710 patients with AF in the Korean National Health Insurance Service database from 2006 to 2015, 1,411 frail patients underwent AF ablations. The Hospital Frailty Risk Score were calculated retrospectively. Inverse probability of treatment weighting (IPTW) was used to categorize ablation and non-ablation frail groups. Results After IPTW, the two cohorts had similar background characteristics. During a median follow-up of 4.7 years (interquartile range: 2.2–7.8), the risk of death in frail patients with ablations was reduced by 65% compared to frail patients without ablations (2.0 and 6.4 per 100 person-years, respectively; hazard ratio [HR] 0.35; 95% confidence interval [CI] 0.25–0.50; P&lt;0.001). Ablations were related with a lower incidence and risk of heart failure admission (1.8 and 3.1 per 100 person-years, respectively; HR 0.66, 95% CI 0.44–0.98; P=0.042) and acute myocardial infarction (0.2 and 0.6 per 100 person-years, respectively; HR 0.30, 95% CI 0.15–0.62; P=0.001). However, the risk of stroke did not change after ablation. Conclussion Ablation may be associated with lower incidences of death, heart failure, and acute myocardial infarction in real-world frail patients with AF, supporting the role of AF ablation in these patients. The effect of frailty risk on the outcome of ablation should be evaluated in further studies. Funding Acknowledgement Type of funding source: None
