Background: Sinoatrial node dysfunction and atrial fibrillation (AF) frequently coexist and interact with each other, often to initiate and perpetuate each other. Objective: To determine the effect of AF on the incidence and risk of sick sinus syndrome (SSS). Methods: The association of incident AF with the development of incident SSS was assessed from 2004 to 2013 in 302,229 SSS- and pacemaker-free participants aged ≥60 years in the Korea National Health Insurance Service-Senior cohort. Results: During an observation period of 1,854,800 person-years, incident AF was observed in a total of 12,797 participants (0.69%/year). The incidence of SSS was 0.2 and 3.4 per 1000 person-years in the incident AF and the propensity score matched no-AF groups, respectively. After adjustment, the risk of SSS caused by incident AF was significantly increased, with a hazard ratio (HR) of 13.4 (95% confidence interval [CI]: 8.4–21.4). This finding was consistently observed after censoring for heart failure (HR, 16.0; 95% CI: 9.2–28.0) or heart failure/myocardial infarction (HR, 16.6; 95% CI: 9.3-29.7). Incident AF also was associated with an increased risk of pacemaker implantation related with both SSS (HR, 21.8; 95% CI: 8.7–18.4) and atrioventricular (AV) block (HR, 9.5; 95% CI: 4.9–18.4). These results were consistent regardless of sex and comorbidities. Conclusion: Incident AF was associated with more than ten times increased risk of SSS in an elderly population regardless of comorbidities. Risk of pacemaker implantations related with both sinus node dysfunction and AV block were increased in elderly population with incident AF.

Background: It is unclear whether exercise would reduce dementia in patients with a new diagnosis of atrial fibrillation (AF). Therefore, we aimed to evaluate the association between the change in physical activity (PA) before and after new-onset AF and the risk of incident dementia. Methods: Using the Korean National Health Insurance Service database, we enrolled a total of 126,555 patients with newly diagnosed AF between 2010 and 2016, who underwent health examinations within two years before and after their diagnosis of AF. The patients were divided into four groups: persistent non-exercisers, exercise starters, exercise quitters, and exercise maintainers. Results: Based on a total of 396,503 person-years of follow-up, 5943 patients were diagnosed with dementia. Compared to persistent non-exercisers, exercise starters (adjusted hazard ratio (aHR) 0.87; 95% confidence interval (CI) 0.81–0.94), and exercise maintainers (aHR 0.66; 95% CI 0.61–0.72) showed a lower risk of incident dementia; however, the risk was similar in exercise quitters (aHR 0.98; 95% CI 0.92–1.05) (p-trend < 0.001). There was a J-shaped relationship between the dose of exercise and the risk of dementia, with the risk reduction maximized at 5–6 times per week of moderate-to-vigorous PA among exercise starters. Conclusion: Patients who initiated or continued regular exercise after diagnosis of AF were associated with a lower risk of dementia than persistent non-exercisers, with no risk reduction associated with exercise cessation. Our findings may provide evidence for the benefit of exercise prescription to patients with new-onset AF to prevent incident dementia regardless of their current exercise status.

Abstract Introduction Anticoagulation therapy is central for the management of stroke in patients with non-valvular atrial fibrillation (NVAF). Persistence with oral anticoagulation is essential to prevent thromboembolic complications. Purpose To assess persistence levels of DOACs and look for possible predictors of treatment discontinuity in NVAF patients. Methods We performed a population-based retrospective cohort study in the Veneto Region (north-eastern Italy, about 5 million inhabitants) using the regional health system databases. Naïve patients initiating direct oral anticoagulants (DOACs) for stroke prevention in NVAF from July 2013 to September 2017 were included in the study. Patients were identified using Anatomical Therapeutic Chemical (ATC) codes, excluding other indications for anticoagulation therapy using ICD-9CM codes. Treatment persistence was defined as the time from initiation to discontinuation of the therapy. Baseline characteristics and comorbidities associated to the persistence of therapy with DOACs were explored by means of Kaplan-Meier curves and assessed through Cox regression. Results Overall, 17920 patients initiated anticoagulation with DOACs in the study period. Most patients were older than 74 years old, while gender was almost equally represented. Comorbidities included hypertension (72%), diabetes mellitus (17%), congestive heart failure (9%), previous stroke/TIA (20%), and prior myocardial infarction (2%). After one year, the persistence to anticoagulation treatment was 82.7%, while the persistence to DOAC treatment was 72.9% with about 10% of the discontinuations being due to switch to VKAs. On multivariate analysis, factors negatively affecting persistence were female gender, younger age (<65 years), renal disease and history of bleeding. Conversely, persistence was better in patients with hypertension, previous cerebral ischemic events, and previous acute myocardial infarction. Persistence to DOAC therapy Conclusion This real-world data show that within 12 months, one out of four anticoagulation-naïve patients stop DOACs, while one out of five patients stop anticoagulation. Efforts should be made to correct modifiable predictors and intensify patient education.

AbstractDiabetes mellitus (DM) is considered an independent risk factor for atrial fibrillation (AF). The excess risk in relation to the presence of proteinuria has not been well elucidated. Our aim was to determine the association between the incidence of AF and proteinuria in diabetic population. A total of 240,499 individuals aged ≥ 60 years from the Korea National Health Insurance Service-Senior cohort from 2004 to 2014 were included. 4.2% of individuals with DM and 3.7% of controls were diagnosed with AF during a median follow-up period of 7.2 years. Amongst controls (participants without proteinuria and DM), DM only, proteinuria only, and DM with proteinuria groups, the crude incidences of AF were 0.58, 0.70, 0.96, 1.24 per 100 person-years respectively. Compared with controls, the weighted risk of AF was increased by 11% (hazard ratio = 1.11, 95% confidence interval = 1.02–1.20, P = .001), 48% (hazard ratio = 1.48, 95% confidence interval = 1.30–1.69, P < .001), and 66% (hazard ratio = 1.66, 95% confidence interval = 1.26–2.18, P < .001) in the DM only, proteinuria only, and DM with proteinuria groups, respectively (P for trend < .001). Degree of proteinuria in diabetic patients was associated with a significantly higher rate of incident AF in dose dependent manner. Thus, assessing proteinuria by a simple urine dipstick test could provide a useful adjunct to risk assessment for AF in elderly population with DM.

Neurologic Deterioration

Introduction: Stroke patients can experience neurological change in the prehospital setting. We sought to identify factors associated with prehospital neurologic deterioration. Methods: Among the Greater Cincinnati/Northern Kentucky region (pop. ~1.3 million), we screened all 15 local hospitals’ admissions from 2010 for acute stroke, and included patients with age ≥20 and complete EMS records. Glasgow Coma Scale (GCS) at hospital arrival was compared with GCS evaluated by EMS, with decrease ≥2 points considered neurologic deterioration. Data obtained included age, sex, race, medical history, antiplatelet or anticoagulant use, stroke subtype [ischemic (IS), ICH, or SAH] and IS subtype (e.g., small vessel, large vessel, cardioembolic), seizure at onset, time from symptom onset to EMS arrival, time from EMS to hospital arrival, blood pressure and serum glucose on EMS arrival, and EMS level of training. Univariate analysis was completed using Wilcoxon rank sum test for continuous measures and chi-square or Fisher’s exact test for categorical measures. Multivariate analysis was completed on variables with p ≤ 0.20 in the univariate analysis. Results: Of 2708 total stroke patients, 1097 (870 IS, 176 ICH, 51 SAH) had EMS records (median [IQR] age 74 [61, 83] years; 56% female; 21% black). Onset to EMS arrival was ≤4.5 hours for 508 cases (46%), and median time from EMS to hospital arrival was 26 minutes. Neurological deterioration occurred in 129 cases (12%), including 9.1% of IS and 22% of ICH/SAH. In multivariate analysis, black race, atrial fibrillation, ICH or SAH subtype, and ALS transport were associated with neurological deterioration. Conclusion: Atrial fibrillation may predict prehospital deterioration in stroke, and preferential transport of patients with acute worsening to centers capable of managing hemorrhagic stroke may be justifiable. Further studies are needed to identify why race is associated with deterioration and potential areas of intervention.

Introduction: Although current alcohol consumption appears to be a risk factor for incident atrial fibrillation (AF), limitations related to self-reported alcohol use and confounding in observational studies limit the certainty of conclusions regarding causality. Whether cessation of alcohol consumption can protect against incident AF remains unknown. Methods: We examined all participants in the Atherosclerosis Risk in Communities (ARIC) study, a population-based cohort of 15,792 men and women aged 45-65, without prevalent AF. Past alcohol consumption was assessed via self-report during the baseline dietary intake assessment. Cases of incident AF were ascertained via study ECGs, hospital discharge ICD-9 codes, and death certificates. Results: Among 15,262 participants with complete survey data, 2,898 (19.0%) were former drinkers. During an average follow-up of 17.4 years, there were 380 cases of incident AF in former consumers. Both before and after adjustment for potential confounders, a longer duration of alcohol abstinence was associated with a lower risk of developing AF; previously consuming alcohol for a longer duration and consuming a greater quantity of alcohol were each associated with a higher risk of developing AF (Table). Conclusions: Among former drinkers, the number of years of drinking and the amount of alcohol consumed may each confer an increased risk of AF. Given that a longer duration of abstinence was associated with a decreased risk of AF, modification of alcohol use could potentially play a role in AF prevention.
