BACKGROUND Acute myocardial infarction may be associated with new-onset arrhythmias. Myocardial infarction patients may manifest with serious arrhythmias such as ventricular tachyarrhythmias or atrial fibrillation. Frequent, prolonged electrocardiogram (ECG) monitoring can prevent devastating outcomes by these arrhythmias. OBJECTIVE We investigated the incidence of arrhythmias in post-myocardial infarction patients using a patch-type device: ATP-C120. METHODS This study is a non-randomized, single-center, prospective cohort study. We evaluated 71 patients with post-myocardial infarction who had been admitted to our hospital. The ATP-C120 device was attached for 11 days and analyzed by two cardiologists for new-onset arrhythmic events. RESULTS One participant was concordantly diagnosed with atrial fibrillation. Atrial premature beats occurred in 91.5% and 84.5% of participants, and ventricular premature beats occurred in 53.5% and 62.0%, respectively. Interestingly, 56.3% of the patients showed less than 2 minutes of sustained paroxysmal atrial tachycardia. Among participants with atrial tachycardia, the use of beta blockers was significantly lower (70.0% vs. 90.3%, p=0.037). However, different dosages of beta blockers did not show significant differences. CONCLUSIONS Wearable patch ECG monitoring devices are easy to apply and can correlate symptoms and ECG rhythm disturbances among post-myocardial infarction patients. Further study is necessary regarding clinical implications and appropriate therapies for arrhythmias detected early, post-myocardial infarction, to prevent adverse outcomes.

Abstract Background Both acute myocardial infarction (AMI) and atrial fibrillation (AF) are risks for stroke. The risk of stroke after AMI may be different in patients with or without AF. The aim of this study was to evaluate the impact of AF on stroke in patients after first AMI. Methods This is a retrospective nationwide cohort study. A total of 170,472 patients who had the primary diagnosis of first AMI between 2000 and 2012 were enrolled. Among them, 8,530 patients with AF were identified. Propensity score matching technique was used to match 8,530 patients without AF with similar ages and genders. All patients were followed until stroke or 31 December 2012, whichever occurred first. Kaplan–Meier cumulative survival curves were constructed to compare stroke between AMI patients with and without AF. Results Overall, 12-year stroke rate was higher in patients with AF than without AF (log rank P-value < 0.001), including in different genders, ages, or intervention subgroups. In patients with AF, those with preexisted AF had higher stroke rates in male gender, age below 65 years, and with intervention subgroups than those with new-onset AF. In Cox proportional-hazard regression analysis, AF was an independent risk factor for stroke after first AMI (hazard ratio, 1.67; 95% confidence interval, 1.5–1.87). Conclusions AF significantly increased stroke risks after first AMI. In patients with AF, those with preexisting AF have higher stroke risks in male genders, ages below 65 years, and with interventions than those with new-onset AF.

Abstract BackgroundNew-onset atrial fibrillation (AF) in critically ill patients is reportedly associated with poor outcomes. However, epidemiological data in intensive care units (ICUs) after new-onset AF identification are lacking. This study aimed to describe the clinical course after the identification of new-onset atrial fibrillation.Methods This prospective cohort study of 32 ICUs in Japan during 2017-2018 enrolled adult patients with new-onset AF. We collected data on patient comorbidities, physiological information before and at the AF onset, interventions, transition of cardiac rhythms, adverse events, and in-hospital death and stroke.Results The incidence of new-onset AF in the ICU was 2.9% (423 patients). At the AF onset, the mean atrial pressure decreased, and the heart rate increased. Sinus rhythm returned spontaneously in 84 patients (20%), and 328 patients (78%) were treated with pharmacological interventions (rate-control drugs, 67%; rhythm-control drugs, 34%). In total, 173 (40%) patients were treated with anticoagulants. Adverse events were more frequent in nonsurvivors than in survivors (bleeding: 14% vs 5%; p = 0.002, arrythmia other than AF: 6% vs 2%; p = 0.048). There were 92 (22%) and 15 patients (4%) patients who continued to have AF at 48 hours and 168 hours after onset, respectively. The hospital mortality rate of those patients were 32% and 60%, respectively. The overall hospital mortality was 26%, and the incidence of in-hospital stroke was 4.5%.Conclusions Although the proportion of patients continued to have AF within 168 hours decreased with various treatments, these patients were at a high risk of death. Moreover, adverse events occurred more frequently in nonsurvivors than in survivors. Further research to assess the management of new-onset AF in critically ill patients is strongly warranted.
