Alcohol Abstinence and the Risk of Atrial Fibrillation in Patients With Newly Diagnosed Type 2 Diabetes Mellitus: A Nationwide Population-Based Study

New-onset atrial fibrillation and chronic coronary syndrome in the CLARIFY registry

BACKGROUND AND AIMS

Data on new-onset atrial fibrillation (NOAF) in patients with chronic coronary syndromes (CCS) are scarce. This study aims to describe the incidence, predictors, and impact on cardiovascular (CV) outcomes of NOAF in CCS patients.

METHODS

Data from the international (45 countries) CLARIFY registry (prospeCtive observational LongitudinAl RegIstry oF patients with stable coronary arterY disease) were used. Among 29 001 CCS outpatients without previously reported AF at baseline, patients with at least one episode of AF/flutter diagnosed during 5-year follow-up were compared with patients in sinus rhythm throughout the study.

RESULTS

The incidence rate of NOAF was 1.12 [95% confidence interval (CI) 1.06-1.18] per 100 patient-years (cumulative incidence at 5 years: 5.0%). Independent predictors of NOAF were increasing age, increasing body mass index, low estimated glomerular filtration rate, Caucasian ethnicity, alcohol intake, and low left ventricular ejection fraction, while high triglycerides were associated with lower incidence. New-onset atrial fibrillation was associated with a substantial increase in the risk of adverse outcomes, with adjusted hazard ratios of 2.01 (95% CI 1.61-2.52) for the composite of CV death, non-fatal myocardial infarction, or non-fatal stroke, 2.61 (95% CI 2.04-3.34) for CV death, 1.64 (95% CI 1.07-2.50) for non-fatal myocardial infarction, 2.27 (95% CI 1.85-2.78) for all-cause death, 8.44 (95% CI 7.05-10.10) for hospitalization for heart failure, and 4.46 (95% CI 2.85-6.99) for major bleeding.

CONCLUSIONS

Among CCS patients, NOAF is common and is strongly associated with worse outcomes. Whether more intensive preventive measures and more systematic screening for AF would improve prognosis in this population deserves further investigation.

Five-year changes in alcohol intake and risk of atrial fibrillation: a Danish cohort study

AIMS

Alcohol intake is a well-established risk factor for atrial fibrillation (AF). However, evidence on the effects of changes in alcohol intake to primary AF prevention is sparse. The aim of this study was to examine the association between 5-year changes in alcohol intake and the risk of incident AF.

METHODS AND RESULTS

This study was based on the Danish cohort study Diet, Cancer and Health. Lifestyle factors were assessed using questionnaires at a recruitment research examination and a second examination 5 years later. Diagnoses of AF and comorbidities were retrieved from the Danish National Patient Registry. 43 758 participants without prior AF were included. The median age was 61 (25th-75th percentile 58-66) years and 54% were female. Over a median follow-up time of 15.7 years, 5312 participants had incident AF (incidence rate 8.6/1000 person-years). Compared with stable intake, increases in alcohol intake to ≥21 drinks/week from ≤6.9 drinks/week (HR: 1.38, 95% CI: 1.09-1.72) or 14-20.9 drinks/week (HR: 1.27, 95% CI: 1.01-1.59) at baseline were associated with a higher risk of AF. In contrast, we did not observe a statistically significant association between reductions in alcohol intake and the risk of AF.

CONCLUSION

A 5-year increase in alcohol intake was associated with a greater risk of AF compared with a stable low/moderate intake.

Association between fatty liver index and risk of end-stage renal disease stratified by kidney function in patients with type 2 diabetes: A nationwide population-based study

OBJECTIVE

The effects of nonalcoholic fatty liver disease on the risk of end-stage renal disease (ESRD) remain unclear. We investigated the association between the fatty liver index (FLI) and risk of ESRD in patients with type 2 diabetes.

METHODS

This population-based observational cohort study enrolled patients with diabetes who underwent health screening between 2009 and 2012 and utilized data from the Korean National Health Insurance Services. The FLI functioned as a surrogate marker for the presence of hepatic steatosis. Chronic kidney disease (CKD) was defined as an estimated glomerular filtration rate < 60 ml/min/1.73 m² calculated using the Modification of Diet in Renal Disease equation. We performed Cox proportional hazards regression.

RESULTS

Incident ESRD developed in 19,476 of 1,900,598 patients with type 2 diabetes during a median follow-up of 7.2 years. After adjusting for conventional risk factors, patients with high FLI scores had a higher risk for ESRD: FLI, 30-59 [hazard ratio (HR) = 1.124; 95% confidence interval (CI), 1.083-1.166]; FLI ≥ 60 [HR = 1.278; 95% CI, 1.217-1.343] compared with those with FLI < 30. The association between a high FLI score (≥ 60) and incident ESRD was more prominent in women than in men (male, FLI ≥60: HR, 1.106; 95% CI = 1.041-1.176 and female, FLI ≥ 60: HR, 1.835; 95% CI = 1.689-1.995). The association between a high FLI score (≥ 60) and the risk of ESRD differed according to baseline kidney function. High FLI scores increased the risk of ESRD (HR = 1.268; 95% CI, 1.198-1.342) in patients with CKD at baseline.

CONCLUSION

High FLI scores are associated with a greater risk of ESRD in patients with type 2 diabetes with CKD at baseline. Close monitoring and appropriate management of hepatic steatosis may aid in preventing the progression of kidney dysfunction in patients with type 2 diabetes and CKD.

The association between alcohol consumption and the risk of hepatocellular carcinoma according to glycemic status in Korea: A nationwide population-based study

BACKGROUND

Alcohol and diabetes are known risk factors for hepatocellular carcinoma (HCC); however, it is unclear whether the association between alcohol consumption and HCC risk differs by fasting serum glucose level and diabetes. We investigated the dose-response relationship between alcohol consumption and the risk of HCC according to glycemic status.

METHODS AND FINDINGS

This population-based observational cohort study included patients who underwent general health checkups in 2009 using the Korean National Health Insurance Service Database. The primary outcome was HCC incidence, and Cox proportional hazard regression analysis was performed to estimate the relationship between alcohol consumption and HCC risk according to glycemic status. A total of 34,321 patients newly diagnosed with HCC were observed in the median follow-up period of 8.3 years. In the multivariable model, we adjusted for age, sex, smoking, regular exercise, income, hypertension, dyslipidemia, and body mass index. Mild-to-moderate alcohol consumption increased the risk of HCC in all glycemic statuses (normoglycemia: hazard ratio [HR], 1.06; 95% confidence interval [CI], 1.02 to 1.10; prediabetes: HR, 1.19; 95% CI, 1.14 to 1.24; and diabetes: HR, 2.02; 95% CI, 1.93 to 2.11) compared to normoglycemic nondrinking. Heavy alcohol consumption also increased the risk of HCC in all glycemic statuses (normoglycemia: HR, 1.39; 95% CI, 1.32 to 1.46; prediabetes: HR, 1.67; 95% CI, 1.58 to 1.77; and diabetes: HR, 3.29; 95% CI, 3.11 to 3.49) compared to normoglycemic nondrinking. Since alcohol consumption information in this study was based on a self-administered questionnaire, there may be a possibility of underestimation. Although we excluded patients with a history of viral hepatitis using diagnosis codes, we could not obtain information on hepatitis B or hepatitis C serum markers.

CONCLUSIONS

Both mild-to-moderate and heavy alcohol consumption was associated with an increased risk of HCC in all glycemic statuses. The increased risk of HCC according to alcohol consumption was the highest in the diabetes group, suggesting that more intensive alcohol abstinence is required for patients with diabetes.

Alcohol and Atrial Fibrillation

Dietary habits, including alcohol consumption, are among the significant risk factors for the occurrence of atrial fibrillation (AF). The pathophysiological relationship between alcohol consumption and AF is complex and multifactorial. However, there is conflicting information about the impact of alcohol consumption (in various doses and types) on the risk of AF and AF-related outcomes. Alcohol consumption is significantly associated with AF in a gender-independent manner. The widespread belief that moderate amounts of alcohol, especially red wine, have cardioprotective effects may mean that more people will use alcohol. Even small amounts of alcohol regularly consumed increase the risk of AF. In this narrative review, we will review the epidemiological associations between alcohol and AF, and the implications for incident AF and AF-related outcomes.

Physical Activity Changes and the Risk of Incident Atrial Fibrillation in Patients With Type 2 Diabetes Mellitus: A Nationwide Longitudinal Follow-up Cohort Study of 1.8 Million Subjects

OBJECTIVE

We investigated the association between alterations in regular physical activity (PA) and the risk of developing AF in patients with type 2 diabetes mellitus (T2DM) and the optimal PA range based on energy expenditure.

RESEARCH DESIGN AND METHODS

In a nationwide database, subjects who underwent health examinations twice at a 2-year interval between 2009 and 2012 were studied. After 1,815,330 patients with T2DM who did not have a history of AF were identified, they were followed until 2018. Regular PA alterations over time were used to divide individuals into four groups: persistent nonexercisers (n = 1,181,837), new exercisers (n = 242,968), exercise dropouts (n = 225,124), and exercise maintainers (n = 165,401).

RESULTS

During a mean follow-up period of 5.6 ± 1.3 years, 46,589 cases (2.6%) of new-onset AF occurred. Compared with the persistent nonexerciser group, both the exercise dropout group (adjusted hazard ratio [HR] 0.96, 95% CI 0.94-0.99) and new exerciser group (HR 0.95, 95% CI 0.93-0.98) had lower risks of incident AF. The exercise maintainer group showed the lowest risk (HR 0.91, 95% CI 0.89-0.94). When we stratified patients with T2DM according to energy expenditure, undergoing regular PA with ≥1,500 MET-min/week in new exercisers and ≥1,000 MET-min/week in exercise maintainers was associated with lower risks of incident AF than nonexercisers.

CONCLUSIONS

In patients with T2DM, starting and maintaining regular PA were both associated with lower risk of incident AF. Optimal PA ranges based on energy expenditure, which were associated with lower risks of incident AF, can be defined.

Cumulative Alcohol Consumption Burden and the Risk of Stroke in Young Adults: A Nationwide Population-Based Study

BACKGROUND AND OBJECTIVE

Alcohol consumption is one of the important modifiable risk factors for stroke in young adults. The association between the cumulative burden of alcohol consumption and its impact on incident stroke in young adults is unknown. We aimed to investigate the association between cumulative alcohol burden and the risk for stroke among young adults.

METHODS

Using data from the Korean National Health Insurance Service database, patients age between 20 and 39 years, who underwent 4 consecutive annual health examinations between 2009 and 2012, were included. The cumulative alcohol burden score of moderate-to-heavy drinking was evaluated by assigning a score of 1 for alcohol consumption ≥105 g/wk at the health examination each year and calculating the sum of 4 years (0-4). The main outcome was incident stroke and its subtypes, ischemic stroke, and hemorrhagic stroke during the follow-up period.

RESULTS

Of 1 536 668 patients (mean age of 29.5 years, 71.5% male, and median follow-up of 6-year), 3 153 experienced an incident stroke (incidence rate, 0.37 per 1,000 person-years). After multivariable adjustment, patients with alcohol burden scores of 2, 3, and 4, who consumed more than 105 g/wk of alcohol for 2, 3, and 4 years, demonstrated significantly higher risks for stroke (hazard ratio [HR] 1.19, 95% CI 1.05-1.34 for 2; HR 1.22, 95% CI 1.09-1.38 for 3; HR 1.23, 95% CI 1.10-1.38 for 4) compared with those with a burden score of 0. This positive dose-response relationship was primarily driven by hemorrhagic rather than ischemic stroke. High alcohol burden scores (i.e., 2, 3, and 4) were significantly associated with higher risks for hemorrhagic stroke (HR 1.30, 95% CI 1.10-1.54 for 2; HR 1.42, 95% CI 1.21-1.67 for 3; HR 1.36, 95% CI 1.16-1.59 for 4) compared with a burden score of 0.

DISCUSSION

Young adults who engaged in moderate-to-heavy drinking demonstrated a higher risk for incident stroke, especially hemorrhagic stroke. Reducing alcohol consumption should be emphasized in young adults with heavy drinking habits as part of any stroke prevention strategy.

[Smoking, heated tobacco products, alcohol and diabetes mellitus (update 2023)]

Smoking and second-hand smoke strongly increase incidence of diabetes and probability for its complications. Smoking cessation can lead to weight gain and increased diabetes risk; however, it decreases cardiovascular and total mortality. A basal diagnostics (Fagerström Test, exhaled CO) is the basis for successful smoking cessation. Supporting medication include Varenicline, Nicotine Replacement Therapy and Bupropion. Socio-economic as well as psychological factors play an important role for smoking and smoking cessation. Heated tobacco products (like the E‑cigarette) are no healthy alternative to cigarettes and are associated with increased morbidity and mortality.Moderate consumption of alcohol possibly decreases risk for diabetes and cardiovascular diseases. Selection bias and underreporting in studies maybe contribute to a too optimistic view. On the other hand, alcohol increases in a dose dependant fashion excess morbidity and disability adjusted life years, especially by cancer, liver diseases and infections.

Effects of Electrical Remodeling on Atrial Fibrillation in Diabetes Mellitus

Atrial fibrillation (AF) is one of the most common arrhythmias in medical practice. Diabetes mellitus (DM) is one of the independent risk factors for atrial fibrillation. The increased morbility of atrial fibrillation in diabetes mellitus is related to both structural and electrical remodeling of atrium. Based on studies of atrial electrophysiological changes in diabetes mellitus, this article focuses on the electrical remodeling of atrial cardiomyocytes, including remodeling of sodium channels, calcium channels, potassium channels and other channels, to provide the basis for the clinical management of antiarrhythmic drugs in diabetic patients with atrial fibrillation.

The association of fatty liver index and BARD score with all-cause and cause-specific mortality in patients with type 2 diabetes mellitus: a nationwide population-based study

BACKGROUND

Type 2 diabetes and non-alcoholic fatty liver disease (NAFLD) commonly coexist. However, NAFLD's effect on mortality in Asian patients with type 2 diabetes awaits full elucidation. Therefore, we examined NAFLD-related all-cause and cause-specific mortality in a nationwide Asian population with type 2 diabetes.

METHODS

We included patients who had undergone general health checkups between 2009 and 2012 using the National Health Insurance Service database linked to death-certificate data. Hepatic steatosis was defined as a fatty liver index (FLI) ≥ 60, and advanced hepatic fibrosis was determined using the BARD score.

FINDINGS

During the follow-up period of 8.1 years, 222,242 deaths occurred, with a mortality rate of 14.3/1000 person-years. An FLI ≥ 60 was significantly associated with increased risks of all-cause and cause-specific mortality including cardiovascular disease (CVD)-, cancer-, and liver disease (FLI ≥ 60: hazard ratio [HR] = 1.02, 95% confidence interval [CI] 1.01-1.03 for all-cause; 1.07, 1.04-1.10 for CVD; 1.12, 1.09-1.14 for cancer; and 2.63, 2.50-2.77 for liver disease). Those with an FLI ≥ 60 and fibrosis (BARD ≥ 2) exhibited increased risks of all-cause (HR, 95% CI 1.11, 1.10-1.12), CVD- (HR, 95% CI 1.11, 1.09-1.14), cancer- (HR, 95% CI 1.17, 1.15-1.19), and liver disease-related (HR, 95% CI 2.38, 2.29-2.49) mortality.

CONCLUSION

Hepatic steatosis and advanced fibrosis were significantly associated with risks of overall and cause-specific mortality in patients with type 2 diabetes. Our results provide evidence that determining the presence of hepatic steatosis and/or fibrosis potentially plays a role in risk stratification of mortality outcomes in patients with type 2 diabetes mellitus.

The impact of socioeconomic deprivation on the risk of atrial fibrillation in patients with diabetes mellitus: A nationwide population-based study

Objective

To evaluate the relationship between socioeconomic status and the risk of atrial fibrillation (AF) in patients with diabetes mellitus (DM).

Research design and methods

From the National Health Insurance Service (NHIS) database, we identified 2,429,610 diabetic patients who underwent national health check-ups between 2009 and 2012. Tracing back the subjects for 5 years from the date of health check-up, we determined the subjects’ income and whether they received medical aid (MA) during the past 5 years. Subjects were divided into six groups according to the number of years of receiving (MA groups 0 through 5) and into four groups according to socioeconomic status change during the past 5 years. We estimated the risk of AF for each group using the Cox proportional-hazards model.

Results

During a median follow-up of 7.2 ± 1.7 years, 80,257 were newly identified as AF. The MA groups showed a higher risk of AF than the non-MA group with the hazard ratios (HRs) and 95% confidence interval (CI) 1.32 (1.2–1.44), 1.33 (1.22–1.45), 1.23 (1.13–1.34), 1.28 (1.16–1.4), and 1.50 (1.39–1.63) for MA groups 1 through 5, respectively. Dividing subjects according to socioeconomic condition change, those who experienced worsening socioeconomic status (non-MA to MA) showed higher risk compared to the persistent non-MA group (HR 1.54; 95% CI 1.38–1.73).

Conclusion

Low socioeconomic status was associated with the risk of AF in patients with diabetes. More attention should be directed at alleviating health inequalities, targeting individuals with socioeconomic deprivation to provide timely management for AF.

Habitual Alcohol Intake and Risk of Atrial Fibrillation in Young Adults in Korea

IMPORTANCE

Guidelines recommend that all risk factors for early-onset atrial fibrillation, including lifestyle factors, be proactively managed, considering the poor prognosis of the disease. Not much is known about the association of cumulative alcohol intake with the risk of atrial fibrillation in young adults aged 20 to 39 years, especially among heavy drinkers.

OBJECTIVE

To explore the association of alcohol consumption with the risk of incident atrial fibrillation in young adults.

DESIGN, SETTING, AND PARTICIPANTS

Using the National Health Insurance Service database, a nationwide population-based cohort study of adults aged 20 to 39 years without prior atrial fibrillation who underwent 4 serial annual health examinations between 2009 and 2012 was conducted. The cumulative alcohol consumption burden over 4 years was calculated by assigning 1 point to more than moderate drinking (≥105 g of alcohol per week) each year. Additionally, a semiquantitative cumulative burden was calculated by assigning 0, 1, 2, and 3 points to non, mild (<105 g per week), moderate (105-210 g per week), and heavy (≥210 g per week) drinking, respectively. Data were analyzed from May to June 2021.

EXPOSURE

Amount of alcohol intake in 4 years.

MAIN OUTCOMES AND MEASURES

The primary outcome was incident atrial fibrillation during the follow-up period.

RESULTS

A total of 1 537 836 participants (mean [SD] age 29.5 [4.1] years, 1 100 099 [71.5%] male) were included in the final analysis. According to the 4-year cumulative burden of alcohol consumption stratified by moderate to heavy drinking, 889 382 participants (57.8%) were in the burden 0 group, 203 374 participants (13.2%) in the burden 1 group, 148 087 participants (9.6%) in the burden 2 group, 144 023 participants (9.4%) in the burden 3 group, and 152 970 participants (9.9%) in the burden 4 group. During a median (IQR) follow-up of 6.13 (4.59-6.48) years, atrial fibrillation was newly diagnosed in 3066 participants (0.36 per 1000 person-years). Participants with a cumulative burden of 4 points who continued more than moderate drinking for 4 years showed a 25% higher risk of atrial fibrillation compared with 0-point participants who kept non-to-mild drinking over 4 years (adjusted HR, 1.25; 95% CI, 1.12-1.40). In a semiquantitative analysis, participants who sustained heavy drinking for 4 consecutive years were associated with a 47% higher atrial fibrillation risk than those who remained nondrinkers over 4 years (aHR, 1.47, CI 1.18-1.83).

CONCLUSIONS AND RELEVANCE

Persistent moderate to heavy drinking and higher cumulative alcohol consumption burden might increase the risk of atrial fibrillation even in young adults aged 20 to 39 years.

The complex interplay between diabetes mellitus and atrial fibrillation

INTRODUCTION

: A growing body of evidence suggests that diabetes mellitus (DM) is associated with an increased risk of new-onset atrial fibrillation (AF) and contributes to suboptimal arrhythmia control and poor prognosis in patients with AF. The high prevalence of AF among patients with DM is primarily attributed to common risk factors, shared pathophysiological mechanisms, and associated atrial remodeling and autonomic dysfunction.

AREAS COVERED

: This comprehensive review covers the current data on the role of DM in the development and prognosis of AF. In addition, we review the impact of anti-DM medications on AF prevention and the role of anticoagulation in patients with coexisting DM and AF.

EXPERT OPINION

: DM is independently associated with new-onset AF, and the coexistence of these two conditions contributes to poor outcomes, from reduced quality of life to increased risks of thromboembolic events, heart failure, and mortality. Despite this strong link, the current evidence is insufficient to recommend routine screening for AF in patients with DM. Although some observations exist on preventing AF with anti-DM medications, randomized controlled trials are warranted to explore the proposed benefits of novel anti-DM medicines in reducing the risk of incident AF.

Combined Effects of Chronic Kidney Disease and Nonalcoholic Fatty Liver Disease on the Risk of Cardiovascular Disease in Patients with Diabetes

Background: We investigated the combined effect of chronic kidney disease (CKD) and nonalcoholic fatty liver disease (NAFLD) on the risk of cardiovascular disease (CVD) in patients with type 2 diabetes. Methods: Data were obtained from the Korean National Health Insurance Service. Patients with diabetes who participated in health screenings from 2009 to 2011 were included. The fatty liver index (FLI) was used as a surrogate marker for NAFLD. Results: During a mean follow-up of 6.9 years, 40,863 incidents of myocardial infarction (MI), 58,427 strokes, and 116,977 deaths were reported in 1,607,232 patients with type 2 diabetes. After adjusting for conventional risk factors, patients with CKD and NAFLD showed the highest risk of MI and stroke (hazard ratio (HR) = 1.49; 95% confidence interval (CI): 1.42–1.57 and stroke, HR = 1.48; 95% CI: 1.41–1.54, respectively) compared with those without either CKD or NAFLD. Both overall and cardiovascular mortality were highest in the CKD/NAFLD group compared with other groups (HR = 2.00; 95% CI: 1.94–2.06, and HR = 2.20; 95% CI: 2.07–2.35, respectively). Advanced liver fibrosis was significantly associated with an increased risk of CVD in patients with NAFLD. Proteinuria was significantly associated with incidence of CVD events in patients with CKD. Conclusions: The combination of CKD and NAFLD was associated with an increased risk of CVD and mortality in patients with type 2 diabetes. Close monitoring and appropriate management of CKD and NAFLD may be warranted to prevent CVD in these patients.

Alcohol Consumption and the Risk of Incident Atrial Fibrillation: A Meta-Analysis

Alcohol consumption is a known, modifiable risk factor for incident atrial fibrillation (AF). However, it remains unclear whether the protective effect of moderate alcohol consumption-that has been reported for various cardiovascular diseases also applies to the risk for new-onset AF. The purpose of this meta-analysis was to evaluate the role of different drinking patterns (low: <14 grams/week; moderate: <168 grams/week; and heavy: >168 grams/week) on the risk for incident AF. Major electronic databases were searched for observational cohorts examining the role of different drinking behaviors on the risk for incident AF. We analyzed 16 studies (13,044,007 patients). Incident AF rate was 2.3%. Moderate alcohol consumption significantly reduced the risk for new-onset AF when compared to both abstainers (logOR: −0.20; 95%CI: −0.28–−0.12; I2: 96.71%) and heavy drinkers (logOR: −0.28; 95%CI: −0.37–−0.18; I2: 95.18%). Heavy-drinking pattern compared to low also increased the risk for incident AF (logOR: 0.14; 95%CI: 0.01–0.2; I2: 98.13%). Substantial heterogeneity was noted, with more homogeneous results documented in cohorts with follow-up shorter than five years. Our findings suggest a J-shaped relationship between alcohol consumption and incident AF. Up to 14 drinks per week seem to decrease the risk for developing AF. Because of the substantial heterogeneity observed, no robust conclusion can be drawn. In any case, our results suggest that the association between alcohol consumption and incident AF is far from being a straightforward dose-response effect.

2021 Focused Update Consensus Guidelines of the Asia Pacific Heart Rhythm Society on Stroke Prevention in Atrial Fibrillation: Executive Summary

The consensus of the Asia Pacific Heart Rhythm Society (APHRS) on stroke prevention in atrial fibrillation (AF) has been published in 2017 which provided useful clinical guidance for cardiologists, neurologists, geriatricians, and general practitioners in the Asia-Pacific region. In these years, many important new data regarding stroke prevention in AF were reported. The practice guidelines subcommittee members comprehensively reviewed updated information on stroke prevention in AF, and summarized them in this 2021 focused update of the 2017 consensus guidelines of the APHRS on stroke prevention in AF. We highlighted and focused on several issues, including the importance of the AF Better Care pathway, the advantages of non-vitamin K antagonist oral anticoagulants (NOACs) for Asians, the considerations of use of NOACs for Asian AF patients with single one stroke risk factor beyond gender, the role of lifestyle factors on stroke risk, the use of oral anticoagulants during the "coronavirus disease 2019" pandemic, etc. We fully realize that there are gaps, unaddressed questions, and many areas of uncertainty and debate in the current knowledge of AF, and the physician's decision remains the most important factor in the management of AF.

The Change in Metabolic Syndrome Status and the Risk of Nonviral Liver Cirrhosis

Background: Nonalcoholic fatty liver disease is considered to be the hepatic component of metabolic syndrome (MetS). However, the association between changes in MetS status and the risk of liver cirrhosis (LC) has not been investigated to date. This study assessed the association between changes in MetS and subsequent nonviral LC development. Methods: Data were obtained from the Korean National Health Insurance Service. Individuals who participated in health screenings from both 2009 to 2010 and 2011 to 2012 were included. The primary outcome was LC development according to the static and dynamic MetS status. Subjects were stratified into four groups according to the change in MetS status observed from the two-year interval screening (2009–2011). Cox regression analysis was used to examine the hazard ratios of LC. Results: During a median of 7.3 years of follow-up, 24,923 incident LC cases developed among 5,975,308 individuals. After adjusting for age, sex, smoking, alcohol, regular exercise, and body mass index, the adjusted hazard ratios (95% confidence intervals) for LC development were 1.39 (1.33–1.44) for the MetS-Developed group, 1.32 (1.26–1.37) for the MetS-Recovered group, and 1.51 (1.45–1.56) for the MetS-Sustained group, relative to the MetS-Free group. Stratified analyses according to age, sex, smoking, alcohol intake, exercise, diabetes mellitus, hypertension, dyslipidemia, and chronic kidney disease showed similar results. Conclusions: Both static and dynamic MetS status are independent risk factors for LC development. The risk of LC was the highest in people with sustained MetS and was lower in the MetS-Recovered group than in the MetS-Sustained group. These results suggest that improving a person’s MetS status may be helpful in preventing LC.

2021 Focused update of the 2017 consensus guidelines of the Asia Pacific Heart Rhythm Society (APHRS) on stroke prevention in atrial fibrillation

The consensus of the Asia Pacific Heart Rhythm Society (APHRS) on stroke prevention in atrial fibrillation (AF) has been published in 2017 which provided useful clinical guidance for cardiologists, neurologists, geriatricians, and general practitioners in Asia-Pacific region. In these years, many important new data regarding stroke prevention in AF were reported. The Practice Guidelines subcommittee members comprehensively reviewed updated information on stroke prevention in AF, and summarized them in this 2021 focused update of the 2017 consensus guidelines of the APHRS on stroke prevention in AF. We highlighted and focused on several issues, including the importance of AF Better Care (ABC) pathway, the advantages of non-vitamin K antagonist oral anticoagulants (NOACs) for Asians, the considerations of use of NOACs for Asian patients with AF with single 1 stroke risk factor beyond gender, the role of lifestyle factors on stroke risk, the use of oral anticoagulants during the "coronavirus disease 2019" (COVID-19) pandemic, etc. We fully realize that there are gaps, unaddressed questions, and many areas of uncertainty and debate in the current knowledge of AF, and the physician's decision remains the most important factor in the management of AF.
