There is limited evidence regarding the risks of incident atrial fibrillation (AF) associated with stage 1 isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH), and systolic-diastolic hypertension (SDH), especially among young adults. We aimed to evaluate the association between early stage of hypertension and AF in young adults. From the Korean nationwide health screening database, 2 958 544 subjects aged 20 to 39 years who were not prescribed antihypertensive medication at the index examination in 2009 were included. Subjects were categorized into 8 groups according to the 2017 American College of Cardiology/American Heart Association blood pressure (BP) guidelines: normal BP, elevated BP, stage 1 IDH, stage 1 ISH, stage 1 SDH, stage 2 IDH, stage 2 ISH, and stage 2 SDH. The primary outcome was new-onset AF. During a median follow-up of 8.3 years, 7347 subjects had incident AF (0.3 per 1000 person-years). Compared with normal BP, stage 1 IDH (adjusted hazard ratio, 1.160 [95% CI, 1.086–1.240]) and stage 1 SDH (1.250 [1.165–1.341]) were associated with higher risks of incident AF, but not stage 1 ISH. Stage 2 IDH, ISH, and SDH were associated with higher risks of incident AF by 24%, 37%, and 61%, respectively. Stage 1 IDH and SDH were associated with higher risks of incident AF compared with normal BP. The risk of incident AF with stage 2 IDH was similar to that of stage 1 SDH. Optimal BP control, including diastolic BP, is associated with the lowest risk of new-onset AF, even among young adults.

Abstract Background There is limited evidence regarding the comparative risks of incident atrial fibrillation (AF) associated with stage 1 isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH), and systolic-diastolic hypertension (SDH), especially amongst young adults aged 20–39 years. Purpose To evaluate the association between early-stage of hypertension and AF in young adults aged 20–39 years. Methods From the Korean nationwide health screening database, 2,958,544 subjects aged 20–39 years who were not prescribed antihypertensive medication at the index examination in 2009 were included. Subjects were categorized into eight groups according to the 2017 American College of Cardiology/American Heart Association blood pressure (BP) guidelines: normal BP, elevated BP, stage 1 IDH, stage 1 ISH, stage 1 SDH, stage 2 IDH, stage 2 ISH, and stage 2 SDH. The primary outcome was new-onset AF during follow-up. Results During a median follow-up of 8.3 years, 7,347 subjects had incident AF (incidence rate, 0.3 per 1,000 person-years). Compared to the normal BP group, stage 1 IDH (adjusted hazard ratio [aHR], 1.160; 95% confidence interval [CI], 1.086–1.240) and stage 1 SDH (1.250; 1.165–1.341) were associated with higher risks of incident AF, but not stage 1 ISH. Stage 2 IDH, ISH, and SDH were associated with higher risks of incident AF by 24%, 37%, and 61%, respectively (Figure). Conclusion Among young adults, stage 1 IDH and SDH were associated with higher risks of incident AF compared to normal BP. The risk of incident AF with stage 2 IDH was similar to that of stage 1 SDH. Optimal BP control including diastolic BP is crucial for preventing new-onset AF, even amongst young adults. FUNDunding Acknowledgement Type of funding sources: None.

Background: Little is known regarding health outcomes associated with isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH), or systolic and diastolic hypertension (SDH) among young adults with stage 1 hypertension, defined using the 2017 American College of Cardiology/American Heart Association blood pressure (BP) guideline. Methods: From a nationwide health screening database, we included 6 424 090 participants, aged 20 to 39 years, who were not taking antihypertensive medication at the baseline examination in 2003 to 2007. Participants were categorized as having normal BP (untreated systolic BP [SBP] <120/diastolic BP [DBP] <80 mm Hg; n=2 665 310); elevated BP (SBP 120–129/DBP <80 mm Hg; n=705 344); stage 1 IDH (SBP <130/DBP 80–89 mm Hg; n=1 271 505); stage 1 ISH (SBP 130–139/DBP <80 mm Hg; n=255 588); stage 1 SDH (SBP 130–139/DBP 80–89 mm Hg; n=711 503); and stage 2 hypertension (SBP ≥140, DBP ≥90 mm Hg; n=814 840). The primary outcome was composite cardiovascular disease (CVD) events, including myocardial infarction, stroke, heart failure, and CVD-related death. Results: The median age of the participants was 30 years and 60.9% were male. Over a median follow-up of 13.2 years, 44 070 new CVD events occurred. With normal BP as the reference, multivariable-adjusted hazard ratios (95% CIs) for CVD events were 1.14 (1.09–1.18) for elevated BP, 1.32 (1.28–1.36) for stage 1 IDH, 1.36 (1.29–1.43) for stage 1 ISH, 1.67 (1.61–1.72) for stage 1 SDH, and 2.40 (2.33–2.47) for stage 2 hypertension. Conclusions: Among young adults, stage 1 ISH, IDH, and SDH were all associated with higher CVD risks than normal BP. The CVD risks of stage 1 ISH and IDH were similar to each other but lower than the risk of stage 1 SDH. Categorizing young adults with stage 1 hypertension further into stage 1 ISH, IDH, and SDH may improve risk stratification for identifying high-risk individuals.

Abstract Background/Introduction Isolated systolic hypertension (ISH) and combined systolic-diastolic hypertension (CH) are related with increased cardiovascular risk. Purpose The aim of the present study was to compare the predictive role of ISH and CH for the incidence of atrial fibrillation (AF) in a cohort of essential hypertensive patients. Methods We followed up 1605 essential hypertensives with office systolic blood pressure (BP)≥140 mmHg [mean age 58.1 years, 842 males, office BP=153/92 mmHg] for a mean period of 8 years. All subjects had at least one annual visit and at baseline underwent echocardiographic study and blood sampling for estimation of metabolic profile. Patients with baseline ISH exhibited office systolic BP ≥140 mmHg and office diastolic BP <90 mmHg, while those with CH had office systolic BP ≥140 mmHg and office diastolic BP ≥90 mmHg. Moreover, new-onset AF was defined as hospitalization for AF or compatible electrocardiographic tracings. Results The incidence of new-onset AF over the follow-up period was 3.4% (n=55). Patients with ISH (n=510) compared to those with CH (n=1095) were older (65±10 vs 55±11 years, p<0.0001), had at baseline lower waist circumference (95.5±12 vs 98±12 cm, p<0.0001), office systolic BP (149±10 vs 155±13 mmHg, p<0.0001), office diastolic BP (80±5 vs 98±7 mmHg, p<0.0001), while did not differ regarding left ventricular mass index and lipid levels (p=NS for all). Univariate Cox regression analysis revealed that baseline ISH (hazard ratio=4.612, p=0.013) and CH (hazard ratio=1.794, p=0.036) predicted new-onset AF. However, in multivariate Cox regression model, age (hazard ratio=1.078, p<0.001), left ventricular mass index (hazard ratio 1.012, p=0.014), left atrium diameter (hazard ratio=1.102, p<0.001) and ISH (hazard ratio=1.551, p=0.035) but not CH turned out to be independent predictors of new-onset AF episodes. Conclusions In essential hypertensive patients, ISH but not CH exhibits independent prognostic value for AF. These findings support that ISH constitutes a hypertensive phenotype of particularly increased arrhythmia risk needing careful evaluation and treatment.

There are limited data on the relationship of acute dental infections with hospitalisation and new-onset atrial fibrillation (AF). This study aimed to assess the relationship between acute periapical abscess and incident AF. This was a retrospective cohort study from a French national database of patients hospitalized in 2013 (3.4 million patients) with at least five years of follow up. In total, 3,056,291 adults (55.1% female) required hospital admission in French hospitals in 2013 while not having a history of AF. Of 4693 patients classified as having dental periapical abscess, 435 (9.27%) developed AF, compared to 326,241 (10.69%) without dental periapical abscess that developed AF over a mean follow-up of 4.8 ± 1.7 years. Multivariable analysis indicated that dental periapical abscess acted as an independent predictor for new onset AF (p < 0.01). The CHA2DS2VASc score in patients with acute dental periapical abscess had moderate predictive value for development of AF, with Area Under the Curve (AUC) 0.73 (95% CI, 0.71–0.76). An increased risk of new onset AF was identified for individuals hospitalized with dental periapical abscess. Careful follow up of patients with severe, acute dental periapical infections is needed for incident AF, as well as investigations of possible mechanisms linking these conditions.

Abstract Background The study aimed to estimate the incidence of and period of progression to stage 2 hypertension from normal blood pressure. Methods We selected a total of 21,172 normotensive individuals between 2003 and 2004 from the National Health Insurance Service-Health Screening and followed them up until 2015. The criteria for blood pressure were based on the American College of Cardiology/American Heart Association 2017 guideline (normal BP: SBP < 120 and DBP < 80 mmHg, elevated BP: SBP 120–129 and DBP < 80 mmHg, stage 1 hypertension: SBP 130–139 or DBP 80–89 mmHg, stage 2 hypertension: SBP ≥140 or DBP ≥ 90 mmHg). We classified the participants into four courses (Course A: normal BP → elevated BP → stage 1 hypertension→ stage 2 hypertension, Course B: normal BP → elevated BP → stage 2 hypertension, Course C: normal BP → stage 1 hypertension → stage 2 hypertension, Course D: normal BP → stage 2 hypertension) according to their progression from normal blood pressure to stage 2 hypertension. Results During the median 12.23 years of follow-up period, 52.8% (n= 11,168) and 23.6% (n=5004) of the participants had stage 1 and stage 2 hypertension, respectively. In particular, over 60 years old had a 2.8-fold higher incidence of stage 2 hypertension than 40–49 years old. After the follow-up period, 77.5% (n=3879) of participants with stage 2 hypertension were found to be course C (n= 2378) and D (n=1501). After the follow-up period, 77.5% (n=3879) of participants with stage 2 hypertension were found to be course C (n= 2378) and D (n=1501). The mean years of progression from normal blood pressure to stage 2 hypertension were 8.7±2.6 years (course A), 6.1±2.9 years (course B), 7.5±2.8 years (course C) and 3.2±2.0 years, respectively. Conclusions This study found that the incidence of hypertension is associated with the progression at each stage. We suggest that the strategies necessary to prevent progression to stage 2 hypertension need to be set differently for each target course.

BackgroundCommunity management of atrial fibrillation (AF) often requires the use of electrocardiographic (ECG) investigation. Patients discharged following treatment of AF with fast ventricular response (fast AF) can require numerous ECGs to monitor rate and/or rhythm control. Single-lead ECGs have been proposed as a more convenient and relatively accurate alternative to 12-lead ECGs for rate/rhythm management and also diagnosis of AF. We aimed to examine the feasibility of using the AliveCor single-lead ECG monitor for diagnosis and monitoring of AF in the community setting.MethodsDuring the course of 6 months, this evaluation of a clinical service improvement pathway used the AliveCor in management of patients requiring (1) follow-up ECGs for AF with previously documented rapid ventricular rate or (2) ECG confirmation of rhythm where AF was suspected. Twelve AliveCor devices provided to the acute community medical team were used to produce 30 s ECG rhythm strips (iECG) that were electronically sent to an overreading physician.ResultsSeventy-four patients (mean age 82 years) were managed on this pathway. (1) The AliveCor was successfully used to monitor the follow-up of 37 patients with fast AF, acquiring a combined total of 113 iECGs (median 1.5 ±3.75 per patient). None of these patients required a subsequent 12-lead ECG and this approach saved an estimate of up to £134.49 per patient. (2) Of 53 patients with abnormal pulses, the system helped identify 8 cases of new onset AF and 19 cases of previously known AF that had reverted from sinus back into AF.ConclusionsWe have demonstrated that the AliveCor system is a feasible, cost-effective, time-efficient and potentially safer alternative to serial 12-lead ECGs for community monitoring and diagnosis of AF.

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.

Obesity has become a pandemic. It is one of the strongest risk-factors of new-onset chronic kidney disease (CKD). However, the effects of obesity and abdominal obesity on the risk of developing CKD in young adults has not been elucidated. From a nationwide health screening database, we included 3,030,884 young adults aged 20–39 years without CKD during a baseline examination in 2009–2010, who could follow up during 2013–2016. Patients were stratified into five levels based on their baseline body mass index (BMI) and six levels based on their waist circumference (WC; 5-cm increments). The primary outcome was the development of CKD. During the follow up, until 2016, 5853 (0.19%) participants developed CKD. Both BMI and WC showed a U-shaped relationship with CKD risk, identifying the cut-off values as a BMI of 21 and WC of 72 cm in young adults. The obesity group (odd ratio [OR] = 1.320, 95% confidence interval [CI]: 1.247–1.397) and abdominal obesity group (male WC ≥ 90, female WC ≥ 85) (OR = 1.208, 95%CI: 1.332–1.290) showed a higher CKD risk than the non-obesity or non-abdominal obesity groups after adjusting for covariates. In the CKD risk by obesity composite, the obesity displayed by the abdominal obesity group showed the highest CKD risk (OR = 1.502, 95%CI: 1.190–1.895), especially in those under 30 years old. During subgroup analysis, the diabetes mellitus (DM) group with obesity or abdominal obesity paradoxically showed a lower CKD risk compared with the non-obesity or non-abdominal obesity group. Obesity and abdominal obesity are associated with increased risk of developing CKD in young adults but a decreased risk in young adults with diabetes.

Background: Little data are available regarding differences in prognosis and health status between new-onset and prior atrial fibrillation (AF) among patients with acute myocardial infarction (AMI). Methods: The TRIUMPH study enrolled 4340 AMI patients who received longitudinal follow-up including SF-12 health status assessments through 1 year post-AMI. We compared 1-year mortality, rehospitalization, and functional status according to AF type (none, prior, new) after adjusting for differences in baseline characteristics. Results: A total of 212 AMI patients (4.9%) had prior AF and 254 (5.9%) had new-onset AF. Compared with no AF, new AF was associated with older age, male sex, first MI, worse baseline physical function, home atrioventricular nodal blocker use, and worse ventricular function (c-index 0.77). Rates of 1-year mortality were 6.2%, 14.5%, and 13.0%, and 1-year rehospitalization rates were 29.1%, 44.2%, and 36.8% for no, prior, and new AF, respectively. After multivariable adjustment, neither prior nor new AF was associated with increased 1-year mortality, and only prior AF was associated with increased risk of 1-year rehospitalization (Figure). After adjusting for baseline SF-12 physical function scores, patients with prior AF had lower 1-year scores than those with no AF (40.6 vs. 43.7, p <0.003), whereas patients with new AF had similar scores (42.9 vs. 43.7, p=0.36). Conclusion: New-onset AF during AMI is associated with a number of comorbidities but, unlike prior AF, is not associated with adverse outcomes. These results raise the question of whether AF is itself a cause of or simply a marker of comorbidities leading to downstream adverse outcomes after AMI.

Abstract Purpose Efficacy of pulmonary vein isolation (PVI) for atrial fibrillation (AF) decreases as left atrial (LA) volume increases. However, surgical AF ablation with unknown efficacy is being performed in patients with a giant LA (GLA). We determined efficacy of thoracoscopic AF ablation in patients with compared to without a GLA. Methods Patients underwent thoracoscopic PVI with additional left atrial ablations lines (in persistent AF) and were prospectively followed up. GLA was defined as LA volume index (LAVI) ≥ 50 ml/m2. Follow-up was performed with ECGs and 24-h Holters every 3 months. After a 3-month blanking period, all antiarrhythmic drugs were discontinued. The primary outcome was freedom of any atrial tachyarrhythmia ≥ 30 s during 2 years of follow-up. Results At baseline, 68 (15.4%) patients had a GLA (LAVI: 56.7 [52.4–62.8] ml/m2), while 374 (84.6%) had a smaller LA (LAVI: 34.8 [29.2–41.3] ml/m2). GLA patients were older (61.9 ± 6.9 vs 59.4 ± 8.8 years, p = 0.02), more often diagnosed with persistent AF (76.5% vs 58.6%, p = 0.008). Sex was equally distributed (with approximately 25% females). GLA patients had more recurrences compared to non-GLA patients at 2-year follow-up (42.6% vs 57.2%, log rank p = 0.02). Freedom of AF was 69.0% in non-GLA paroxysmal AF patients compared to 43.8–49.3% in a combined group of GLA and/or persistent AF patients(log rank p < 0.001). Furthermore, freedom was 62.4% in non-GLA male patients, compared to 43.8–47.4 in a combined group of GLA and/or female sex(log rank p = 0.02). Conclusion Thoracoscopic AF ablation is an effective therapy in a substantial part of GLA patients. Thoracoscopic AF ablation may serve as a last resort treatment option in these patients.
