Safety and efficacy of long-term sodium channel blocker therapy for early rhythm control: the EAST-AFNET 4 trial.

AIMS: Clinical concerns exist about the potential proarrhythmic effects of the sodium channel blockers (SCBs) flecainide and propafenone in patients with cardiovascular disease. Sodium channel blockers were used to deliver early rhythm control (ERC) therapy in EAST-AFNET 4. METHODS AND RESULTS: We analysed the primary safety outcome (death, stroke, or serious adverse events related to rhythm control therapy) and primary efficacy outcome (cardiovascular death, stroke, and hospitalization for worsening of heart failure (HF) or acute coronary syndrome) during SCB intake for patients with ERC (n = 1395) in EAST-AFNET 4. The protocol discouraged flecainide and propafenone in patients with reduced left ventricular ejection fraction and suggested stopping therapy upon QRS prolongation >25% on therapy. Flecainide or propafenone was given to 689 patients [age 69 (8) years; CHA2DS2-VASc 3.2 (1); 177 with HF; 41 with prior myocardial infarction, coronary artery bypass graft, or percutaneous coronary intervention; 26 with left ventricular hypertrophy >15 mm; median therapy duration 1153 [237, 1828] days]. The primary efficacy outcome occurred less often in patients treated with SCB [3/100 (99/3316) patient-years] than in patients who never received SCB [SCBnever 4.9/100 (150/3083) patient-years, P < 0.001]. There were numerically fewer primary safety outcomes in patients receiving SCB [2.9/100 (96/3359) patient-years] than in SCBnever patients [4.2/100 (135/3220) patient-years, adjusted P = 0.015]. Sinus rhythm at 2 years was similar between groups [SCB 537/610 (88); SCBnever 472/579 (82)]. CONCLUSION: Long-term therapy with flecainide or propafenone appeared to be safe in the EAST-AFNET 4 trial to deliver effective ERC therapy, including in selected patients with stable cardiovascular disease such as coronary artery disease and stable HF.

ACES: A new framework for the application of the 2018 periodontal status classification scheme to epidemiological survey data.

AIM: To propose a framework for consistently applying the 2018 periodontal status classification scheme to epidemiological surveys (Application of the 2018 periodontal status Classification to Epidemiological Survey data, ACES). PROPOSED FRAMEWORK: We specified data requirements and workflows for either completed or planned epidemiological surveys, utilizing commonly collected measures of periodontal status (clinical attachment levels [CAL], probing depths, bleeding on probing), as well as additional necessary variables for the implementation of the 2018 periodontal status classification (tooth loss due to periodontitis and complexity factors). Following detailed instructions and flowcharts, survey participants are classified as having periodontal health, gingivitis or periodontitis. Rates of edentulism must also be reported. In cases of periodontitis, instructions on how to compute the stage and extent are provided. Assessment of grade can be derived from CAL measurements (or from radiographic alveolar bone loss data) in relation to root length and the participant's age. CONCLUSIONS: ACES is a framework to be used in epidemiological studies of periodontal status that (i) have been completed, and in which stage and grade according to the 2018 classification are inferred retroactively, or (ii) are being planned. Consistent use of the proposed comprehensive approach will facilitate the comparability of periodontitis prevalence estimates across studies.

Early Rhythm Control in Patients With Atrial Fibrillation and High Comorbidity Burden.

BACKGROUND: The randomized EAST-AFNET4 (Early Treatment of Atrial Fibrillation for Stroke Prevention Trial-Atrial Fibrillation Network) demonstrated that early rhythm control (ERC) reduces adverse cardiovascular outcomes in patients with recently diagnosed atrial fibrillation and stroke risk factors. The effectiveness and safety of ERC in patients with multiple cardiovascular comorbidities is not known. METHODS: These prespecified subanalyses of EAST-AFNET4 compared the effectiveness and safety of ERC with usual care (UC) stratified into patients with higher (CHA2DS2-VASc score ≥4) and lower comorbidity burden. Sensitivity analyses ignored sex (CHA2DS2-VA score). RESULTS: EAST-AFNET4 randomized 1093 patients with CHA2DS2-VASc score ≥4 (74.8±6.8 years, 61% female) and 1696 with CHA2DS2-VASc score <4 (67.4±8.0 years, 37% female). ERC reduced the composite primary efficacy outcome of cardiovascular death, stroke, or hospitalization for worsening of heart failure or for acute coronary syndrome in patients with CHA2DS2-VASc score ≥4 (ERC, 127/549 patients with events; UC, 183/544 patients with events; hazard ratio [HR], 0.64 [0.51-0.81]; P < 0.001) but not in patients with CHA2DS2-VASc score <4 (ERC, 122/846 patients with events; UC, 133/850 patients with events; HR, 0.93 [0.73-1.19]; P=0.56, Pinteraction=0.037). The primary safety outcome (death, stroke, or serious adverse events of rhythm control therapy) was not different between study groups in patients with CHA2DS2-VASc score ≥4 (ERC, 112/549 patients with events; UC, 132/544 patients with events; HR, 0.84 [0.65, 1.08]; P=0.175), but occurred more often in patients with CHA2DS2-VASc scores <4 randomized to ERC (ERC, 119/846 patients with events; UC, 91/850 patients with events; HR, 1.39 [1.05-1.82]; P=0.019, Pinteraction=0.008). Life-threatening events or death were not different between groups (CHA2DS2-VASc score ≥4, ERC, 84/549 patients with event, UC, 96/544 patients with event; CHA2DS2-VASc scores <4, ERC, 75/846 patients with event, UC, 73/850 patients with event). When female sex was ignored for the creation of higher and lower risk groups (CHA2DS2-VA score), the Pinteraction was not significant for the primary efficacy outcome (P=0.25), but remained significant (P=0.044) for the primary safety outcome. CONCLUSIONS: Patients with recently diagnosed atrial fibrillation and CHA2DS2-VASc score ≥4 should be considered for ERC to reduce cardiovascular outcomes, whereas those with fewer comorbidities may have less favorable outcomes with ERC.

SARS-CoV-2 Vaccination-Induced Immunogenicity in Heart Transplant Recipients.

Among heart transplant (HT) recipients, a reduced immunological response to SARS-CoV-2 vaccination has been reported. We aimed to assess the humoral and T-cell response to SARS-CoV-2 vaccination in HT recipients to understand determinants of immunogenicity. HT recipients were prospectively enrolled from January 2021 until March 2022. Anti-SARS-CoV-2-Spike IgG levels were quantified after two and three doses of a SARS-CoV-2 vaccine (BNT162b2, mRNA1273, or AZD1222). Spike-specific T-cell responses were assessed using flow cytometry. Ninety-one patients were included in the study (69% male, median age 55 years, median time from HT to first vaccination 6.1 years). Seroconversion rates were 34% after two and 63% after three doses. Older patient age (p = 0.003) and shorter time since HT (p = 0.001) were associated with lower antibody concentrations after three vaccinations. There were no associations between vaccine types or immunosuppressive regimens and humoral response, except for prednisolone, which was predictive of a reduced response after two (p = 0.001), but not after three doses (p = 0.434). A T-cell response was observed in 50% after two and in 74% after three doses. Despite three vaccine doses, a large proportion of HT recipients exhibits a reduced immune response. Additional strategies are desirable to improve vaccine immunogenicity in this vulnerable group of patients.

Association between periodontal disease and microstructural brain alterations in the Hamburg City Health Study.

AIM: The aim of the PAROBRAIN study was to examine the association of periodontal health with microstructural white matter integrity and cerebral small vessel disease (CSVD) in the Hamburg City Health Study, a large population-based cohort with dental examination and brain magnetic resonance imaging (MRI). MATERIALS AND METHODS: Periodontal health was determined by measuring clinical attachment loss (CAL) and plaque index. Additionally, the decayed/missing/filled teeth (DMFT) index was quantified. 3D-FLAIR and 3D-T1-weighted images were used for white matter hyperintensity (WMH) segmentation. Diffusion-weighted MRI was used to quantify peak width of skeletonized mean diffusivity (PSMD). RESULTS: Data from 2030 participants were included in the analysis. Median age was 65 years, with 43% female participants. After adjusting for age and sex, an increase in WMH load was significantly associated with more CAL, higher plaque index and higher DMFT index. PSMD was significantly associated with the plaque index and DMFT. Additional adjustment for education and cardiovascular risk factors revealed a significant association of PSMD with plaque index (p < .001) and DMFT (p < .01), whereas effects of WMH load were attenuated (p > .05). CONCLUSIONS: These findings suggest an adverse effect of periodontal health on CSVD and white matter integrity. Further research is necessary to examine whether early treatment of periodontal disease can prevent microstructural brain damage.

Attaining sinus rhythm mediates improved outcome with early rhythm control therapy of atrial fibrillation: the EAST-AFNET 4 trial.

AIMS: A strategy of systematic, early rhythm control (ERC) improves cardiovascular outcomes in patients with atrial fibrillation (AF). It is not known how this outcome-reducing effect is mediated. METHODS AND RESULTS: Using the Early treatment of Atrial Fibrillation for Stroke prevention Trial (EAST-AFNET 4) data set, potential mediators of the effect of ERC were identified in the total study population at 12-month follow up and further interrogated by use of a four-way decomposition of the treatment effect in an exponential model predicting future primary outcome events. Fourteen potential mediators of ERC were identified at the 12-month visit. Of these, sinus rhythm at 12 months explained 81% of the treatment effect of ERC compared with usual care during the remainder of follow up (4.1 years). In patients not in sinus rhythm at 12 months, ERC did not reduce future cardiovascular outcomes (hazard ratio 0.94, 95% confidence interval 0.65-1.67). Inclusion of AF recurrence in the model only explained 31% of the treatment effect, and inclusion of systolic blood pressure at 12 months only 10%. There was no difference in outcomes in patients who underwent AF ablation compared with those who did not undergo AF ablation. CONCLUSION: The effectiveness of early rhythm control is mediated by the presence of sinus rhythm at 12 months in the EAST-AFNET 4 trial. Clinicians implementing ERC should aim for rapid and sustained restoration of sinus rhythm in patients with recently diagnosed AF and cardiovascular comorbidities.

Systematic, early rhythm control strategy for atrial fibrillation in patients with or without symptoms: the EAST-AFNET 4 trial.

AIMS: Clinical practice guidelines restrict rhythm control therapy to patients with symptomatic atrial fibrillation (AF). The EAST-AFNET 4 trial demonstrated that early, systematic rhythm control improves clinical outcomes compared to symptom-directed rhythm control. METHODS AND RESULTS: This prespecified EAST-AFNET 4 analysis compared the effect of early rhythm control therapy in asymptomatic patients (EHRA score I) to symptomatic patients. Primary outcome was a composite of death from cardiovascular causes, stroke, or hospitalization with worsening of heart failure or acute coronary syndrome, analyzed in a time-to-event analysis. At baseline, 801/2633 (30.4%) patients were asymptomatic [mean age 71.3 years, 37.5% women, mean CHA2DS2-VASc score 3.4, 169/801 (21.1%) heart failure]. Asymptomatic patients randomized to early rhythm control (395/801) received similar rhythm control therapies compared to symptomatic patients [e.g. AF ablation at 24 months: 75/395 (19.0%) in asymptomatic; 176/910 (19.3%) symptomatic patients, P = 0.672]. Anticoagulation and treatment of concomitant cardiovascular conditions was not different between symptomatic and asymptomatic patients. The primary outcome occurred in 79/395 asymptomatic patients randomized to early rhythm control and in 97/406 patients randomized to usual care (hazard ratio 0.76, 95% confidence interval [0.6; 1.03]), almost identical to symptomatic patients. At 24 months follow-up, change in symptom status was not different between randomized groups (P = 0.19). CONCLUSION: The clinical benefit of early, systematic rhythm control was not different between asymptomatic and symptomatic patients in EAST-AFNET 4. These results call for a shared decision discussing the benefits of rhythm control therapy in all patients with recently diagnosed AF and concomitant cardiovascular conditions (EAST-AFNET 4; ISRCTN04708680; NCT01288352; EudraCT2010-021258-20).

[Association of oral health literacy and behaviour with physical oral health. What role can dental education play?] / Zusammenhang von Mundgesundheitskompetenz und -verhalten mit physischer Mundgesundheit. Welche Rolle kann die zahnmedizinische Ausbildung spielen?

BACKGROUND: Oral health is an essential component of a person's general health and well-being. It is influenced by many factors. These include individual aspects such as oral health literacy and oral health behaviour. The aim of this study was to investigate the association between oral health literacy and behaviour with physical oral health. METHODS: In this population-based cross-sectional study, data of 5510 subjects enrolled in the Hamburg City Health Study (HCHS) from 2016 to 2018 with a mean age of 62.1 years and 50.7% women were evaluated. Physical oral health was assessed using the 14-item Physical Oral Health Index (PhOX). A newly developed 10-item questionnaire based on the Oral Health Literacy Adult Questionnaire and the 5th German Oral Health Study were used to determine oral health literacy and behaviour. RESULTS: The sum score of the 10 questions related to oral health literacy and behaviour significantly correlated with the PhOX sum score (r = 0.23; p < 0.001). An increase of one point in the total score of oral health literacy and behaviour was associated with an increase in the PhOX sum score of 1.45 points on average. This association decreased only marginally after integrating potential confounders such as age and education. CONCLUSION: Higher oral health literacy and better oral health behaviour are associated with better physical oral health. Oral health literacy and behaviour should be important targets in dental education to efficiently and sustainably improve the oral health of the general population.

Association Between Carotid Atherosclerosis and Atrial Fibrillation, Cardiac, and Renal Function.

OBJECTIVE: The aim was to analyse whether the association between carotid atherosclerosis (CA) and atrial fibrillation (AF), heart function, and renal function is mediated by traditional risk factors. METHODS: In the prospective, single centre, long term, population based Hamburg City Health Study citizens, between 45 and 74 years of age were studied by cross sectional analysis of the first cohort. Laboratory values, blood pressure, heart rhythm, and body mass index (BMI) were examined. Carotid intima media thickness (CIMT) and plaques were assessed by carotid ultrasound, and CA was defined as either CIMT ≥ 1 mm or presence of plaques or both. N-terminal pro-brain natriuretic peptide (NT-proBNP), and glomerular filtration rate (eGFR) were quantified as measures of heart and renal function. Association between CA and AF, NT-proBNP, and eGFR was analysed by multivariable linear and logistic regression. RESULTS: Of the first 10 000 participants, carotid ultrasound was available for 9 466 (95%). Of these, 2 937 (31%) had carotid plaques, 643 (7%) had CIMT ≥ 1 mm, and 412 (4%) presented with both, so that 3 168 (34%) had CA. Participants with CA had AF more frequently (9.6% vs. 4.3%; p < .001), higher levels of NT-proBNP (median 100 vs. 73 pg/mL; p < .001), and lower eGFR (82.8 vs. 87.1 mL/min; p < .001) than those without CA. Adjusted for age and sex, CA was associated with AF (p = .01; OR 1.29) and higher NT-proBNP levels (p < .001; ß = 0.12), but not with eGFR. After further adjustment for vascular risk factors and history of cardiovascular diseases, CA remained associated with NT-proBNP (p < .001; ß = 0.10), but additionally adjusted for NT-proBNP (p < .001; OR 2.80) not with AF. CONCLUSION: CA is independently associated with higher levels of NT-proBNP, through common risk factors and NT-proBNP with AF, and not with renal function. CA's association with a marker of cardiac dysfunction beyond known common risk factors supports the value of carotid ultrasound in defining patients' cardiovascular risk profile. The measures of CA, i.e., CIMT and carotid plaque, had an equally directed and additive influence.

Cross-sectional analysis of the association of periodontitis with carotid intima media thickness and atherosclerotic plaque in the Hamburg City health study.

BACKGROUND: Previous epidemiological studies regarding the association between chronic periodontitis (CP) and carotid intima-media thickness (cIMT) and subclinical atherosclerosis have been inconclusive. OBJECTIVE: The aim of this study was to determine whether CP is associated with subclinical atherosclerosis in a large population-based cohort study conducted in northern Germany (the Hamburg City Health study). METHODS: Baseline data from 5781 participants of the Hamburg City Health Study with complete oral health and carotid ultrasound data (50.7% female, mean age: 62.1 ± 8.4 years) were evaluated. A standardized duplex sonography of the carotid artery was performed with measurement of carotid intima-media thickness (cIMT) and atherosclerotic plaques. Oral health was assessed by recording the decayed, missing, and filled teeth (DMFT) index, clinical attachment loss (CAL), bleeding on probing (BOP), and the dental plaque index (PI). Correlations were tested for statistical significance by means of descriptive statistics and multivariate regression analyses. RESULTS: Moderate and severe CP were associated with the prevalence of cIMT ≥ 1 mm (none or mild CP: 5.1%, moderate CP: 6.1%, severe CP: 10%) and mean cIMT (none or mild CP: 0.72 mm, moderate CP: 0.75 mm, severe CP: 0.78 mm) in bivariate analyses (p < .001). Additionally, severe and moderate CP were associated with higher prevalence of carotid atherosclerotic plaques (plaque = yes: none or mild CP: 23.9%, moderate CP: 29%, severe CP: 40.2%,). After adjustment for age, sex, smoking, diabetes, hypertension, educational level, hypercholesterolemia, and hsCRP, severe CP still correlated significantly with cIMT and the prevalence of cIMT ≥1 mm and/or presence of carotid atherosclerotic plaques. CONCLUSION: In this study, severe CP was associated with increased cIMT and higher prevalence of carotid plaques independent of common risk factors.

Evidence from the Hamburg City Health Study - association between education and periodontitis.

OBJECTIVE: Large-scale population-based studies regarding the role of education in periodontitis are lacking. Thus, the aim of the current study was to analyze the potential association between education and periodontitis with state of the art measured clinical phenotypes within a large population-based sample from northern Germany. MATERIAL & METHODS: The Hamburg City Health Study (HCHS) is a population-based cohort study registered at ClinicalTrial.gov (NCT03934957). Oral health was assessed via plaque-index, probing depth, gingival recession and gingival bleeding. Periodontitis was classified according to Eke & Page. Education level was determined using the International Standard Classification of Education (ISCED-97) further categorized in "low, medium or high" education. Analyses for descriptive models were stratified by periodontitis severity. Ordinal logistic regression models were stepwise constructed to test for hypotheses. RESULTS: Within the first cohort of 10,000 participants, we identified 1,453 with none/mild, 3,580 with moderate, and 1,176 with severe periodontitis. Ordinal regression analyses adjusted for co-variables (age, sex, smoking, diabetes, hypertension and migration) showed that the education level (low vs. high) was significantly associated with periodontitis (OR: 1.33, 95% CI: 1.18;1.47). CONCLUSION: In conclusion, the current study revealed a significant association between the education level and periodontitis after adjustments for a set of confounders. Further research is needed to develop strategies to overcome education related deficits in oral and periodontal health.

The association between coffee consumption and periodontitis: a cross-sectional study of a northern German population.

BACKGROUND: Positive and negative influences on oral health are attributed to coffee consumption. The aim of the current study is to evaluate the association between coffee consumption and periodontitis in the general population of Hamburg. METHODS: A total of 6,209 participants from the Hamburg City Health Study were included in this cross-sectional study. Information on coffee consumption was collected using a food frequency questionnaire. Periodontal examination included assessment of dental care ability via Plaque Index, measurement of pocket depth, gingival recession, and bleeding on probing. Classification was based on the criteria of Eke and Page. Ordinal logistic regression models were performed unadjusted and adjusted for confounding variables. RESULTS: Periodontal cohort consists of 6,209 participants, presenting either none/mild (n = 1,453, 39.6% men, 2.4% strong coffee drinkers), moderate (n = 3,580, 49.3% men, 3.3% strong coffee drinkers), or severe (n = 1,176, 60.9% men, 5.0% strong coffee drinkers) periodontitis. There was a significant association between strong coffee consumption (≥ 7or more cups/day) and periodontitis (OR: 1.51; CI: 1.07, 2.12; p > 0.001), compared with low coffee consumption. Conversely, moderate coffee consumption was not associated with periodontitis, compared with low coffee consumption. CONCLUSION: and clinical relevance. In this cross-sectional study of a northern German population, strong coffee consumption was significantly associated with periodontitis. Influence of changes in coffee consumption on periodontal disease etiology/progression should be investigated in future prospective study designs, in order to identify strong coffee consumption as a potential risk factor of periodontitis.

White matter integrity and structural brain network topology in cerebral small vessel disease: The Hamburg city health study.

Cerebral small vessel disease is a common finding in the elderly and associated with various clinical sequelae. Previous studies suggest disturbances in the integration capabilities of structural brain networks as a mediating link between imaging and clinical presentations. To what extent cerebral small vessel disease might interfere with other measures of global network topology is not well understood. Connectomes were reconstructed via diffusion weighted imaging in a sample of 930 participants from a population based epidemiologic study. Linear models were fitted testing for an association of graph-theoretical measures reflecting integration and segregation with both the Peak width of Skeletonized Mean Diffusivity (PSMD) and the load of white matter hyperintensities of presumed vascular origin (WMH). The latter were subdivided in periventricular and deep for an analysis of localisation-dependent correlations of cerebral small vessel disease. The median WMH volume was 0.6 mL (1.4) and the median PSMD 2.18 mm2 /s x 10-4 (0.5). The connectomes showed a median density of 0.880 (0.030), the median values for normalised global efficiency, normalised clustering coefficient, modularity Q and small-world propensity were 0.780 (0.045), 1.182 (0.034), 0.593 (0.026) and 0.876 (0.040) respectively. An increasing burden of cerebral small vessel disease was significantly associated with a decreased integration and increased segregation and thus decreased small-worldness of structural brain networks. Even in rather healthy subjects increased cerebral small vessel disease burden is accompanied by topological brain network disturbances. Segregation parameters and small-worldness might as well contribute to the understanding of the known clinical sequelae of cerebral small vessel disease.

Rationale and Design of the Hamburg City Health Study.

The Hamburg City Health Study (HCHS) is a large, prospective, long-term, population-based cohort study and a unique research platform and network to obtain substantial knowledge about several important risk and prognostic factors in major chronic diseases. A random sample of 45,000 participants between 45 and 74 years of age from the general population of Hamburg, Germany, are taking part in an extensive baseline assessment at one dedicated study center. Participants undergo 13 validated and 5 novel examinations primarily targeting major organ system function and structures including extensive imaging examinations. The protocol includes validate self-reports via questionnaires regarding lifestyle and environmental conditions, dietary habits, physical condition and activity, sexual dysfunction, professional life, psychosocial context and burden, quality of life, digital media use, occupational, medical and family history as well as healthcare utilization. The assessment is completed by genomic and proteomic characterization. Beyond the identification of classical risk factors for major chronic diseases and survivorship, the core intention is to gather valid prevalence and incidence, and to develop complex models predicting health outcomes based on a multitude of examination data, imaging, biomarker, psychosocial and behavioral assessments. Participants at risk for coronary artery disease, atrial fibrillation, heart failure, stroke and dementia are invited for a visit to conduct an additional MRI examination of either heart or brain. Endpoint assessment of the overall sample will be completed through repeated follow-up examinations and surveys as well as related individual routine data from involved health and pension insurances. The study is targeting the complex relationship between biologic and psychosocial risk and resilience factors, chronic disease, health care use, survivorship and health as well as favorable and bad prognosis within a unique, large-scale long-term assessment with the perspective of further examinations after 6 years in a representative European metropolitan population.

Blood-based cardiometabolic phenotypes in atrial fibrillation and their associated risk: EAST-AFNET 4 biomolecule study.

AIMS: Atrial fibrillation (AF) and concomitant cardiometabolic disease processes interact and combine to lead to adverse events, such as stroke, heart failure, myocardial infarction, and cardiovascular death. Circulating biomolecules provide quantifiable proxies for cardiometabolic disease processes. The aim of this study was to test whether biomolecule combinations can define phenotypes in patients with AF. METHODS AND RESULTS: This pre-specified analysis of the EAST-AFNET 4 biomolecule study assigned patients to clusters using polytomous variable latent-class analysis based on baseline concentrations of 13 precisely quantified biomolecules potentially reflecting ageing, cardiac fibrosis, metabolic dysfunction, oxidative stress, cardiac load, endothelial dysfunction, and inflammation. In each cluster, rates of cardiovascular death, stroke, or hospitalization for heart failure or acute coronary syndrome, the primary outcome of EAST-AFNET 4, were calculated and compared between clusters over median 5.1 years follow-up. Findings were independently validated in a prospective cohort of 748 patients with AF (BBC-AF; median follow-up 2.9 years).Unsupervised biomolecule analysis assigned 1586 patients (71 years old, 46% women) into four clusters. The highest risk cluster was dominated by elevated bone morphogenetic protein 10, insulin-like growth factor-binding protein 7, N-terminal pro-B-type natriuretic peptide, angiopoietin 2, and growth differentiation factor 15. Patients in the lowest risk cluster showed low concentrations of these biomolecules. Two intermediate-risk clusters differed by high or low concentrations of C-reactive protein, interleukin-6, and D-dimer. Patients in the highest risk cluster had a five-fold higher cardiovascular event rate than patients in the low-risk cluster. Early rhythm control was effective across clusters (Pinteraction = 0.63). Sensitivity analyses and external validation in BBC-AF replicated clusters and risk gradients. CONCLUSION: Biomolecule concentrations identify cardiometabolic subphenotypes in patients with AF at high and low cardiovascular risk.

Association between an Anti-Inflammatory Dietary Score and Periodontitis-Evidence from the Population-Based Hamburg City Health Study.

While the effects of dietary patterns on cardiovascular risk and diabetes have been well studied, the evidence is scarce as to which diet has the greatest anti-inflammatory potential and how dietary patterns are associated with periodontitis. In the Hamburg City Health Study (HCHS), we developed an anti-inflammatory dietary score using a data-driven approach based on the relationship of relevant selected food groups with inflammatory biomarkers (hsCRP and IL-6). The aim of this cross-sectional study was to evaluate the association between the anti-inflammatory dietary score and the incidence of periodontitis in Hamburg, Germany. A total of n = 5642 participants fit the required inclusion criteria and were selected for analysis. Periodontal disease was assessed using probing depth, gingival recession, and bleeding on probing. Dietary intake was measured using a food frequency questionnaire (FFQ). A self-developed anti-inflammatory dietary score served as the key explanatory variable. Higher scores reflected lower inflammatory processes (measured through the biomarkers hsCRP and IL-6). Several covariates were included in the regression analysis. Regressions revealed that a higher anti-inflammatory dietary score was significantly associated with lower odds to be affected by periodontal disease in an unadjusted model (OR 0.86, 95% CI 0.82-0.89, p < 0.001) and in an adjusted model (age, sex, smoking, diabetes, hypertension, and physical activity) (OR 0.93, 95% CI 0.89-0.98, p = 0.003). Our study demonstrated a significant inverse association between an anti-inflammatory dietary score and periodontitis. Individuals with higher intake of proinflammatory nutrition should be specifically addressed to avoid periodontitis.

Association between Coffee Consumption and Brain MRI Parameters in the Hamburg City Health Study.

Despite associations of regular coffee consumption with fewer neurodegenerative disorders, its association with microstructural brain alterations is unclear. To address this, we examined the association of coffee consumption with brain MRI parameters representing vascular brain damage, neurodegeneration, and microstructural integrity in 2316 participants in the population-based Hamburg City Health Study. Cortical thickness and white matter hyperintensity (WMH) load were measured on FLAIR and T1-weighted images. Microstructural white matter integrity was quantified as peak width of skeletonized mean diffusivity (PSMD) on diffusion-weighted MRI. Daily coffee consumption was assessed in five groups (<1 cup, 1-2 cups, 3-4 cups, 5-6 cups, >6 cups). In multiple linear regressions, we examined the association between brain MRI parameters and coffee consumption (reference group <1 cup). After adjustment for covariates, 3-4 cups of daily coffee were associated with lower PSMD (p = 0.028) and higher cortical thickness (p = 0.015) compared to <1 cup. Moreover, 1-2 cups per day was also associated with lower PSMD (p = 0.022). Associations with WMH load or other groups of coffee consumption were not significant (p > 0.05). The findings indicate that regular coffee consumption is positively associated with microstructural white matter integrity and cortical thickness. Further research is necessary to determine longitudinal effects of coffee on brain microstructure.

Early rhythm-control therapy for atrial fibrillation in patients with a history of stroke: a subgroup analysis of the EAST-AFNET 4 trial.

BACKGROUND: Patients with atrial fibrillation and a history of stroke are at high risk of recurrent stroke and cardiovascular complications. In the EAST-AFNET 4 trial we showed that a systematic strategy of early rhythm control was associated with a lower risk of cardiovascular outcomes than usual care in patients with atrial fibrillation diagnosed in the past 12 months. In this pre-specified subgroup analysis we aimed to assess whether a strategy of early rhythm control is safe and can prevent adverse cardiovascular outcomes compared with usual care in such patients. METHODS: EAST-AFNET 4 was a randomised, open-label trial with blinded-outcome assessment done at 135 hospitals and secondary care practices in 11 European countries. Adults with early atrial fibrillation (ie, diagnosed ≤12 months before enrolment) were randomly assigned (1:1) to either early rhythm control or usual care, with stratification according to site and variable block lengths used for concealment. The first primary outcome was time to first occurrence of the composite of cardiovascular death, ischaemic or haemorrhagic stroke, or hospital admission with worsening of heart failure or acute coronary syndrome. The second primary outcome was the number of nights spent in hospital in 1 year. The primary safety outcome was the composite of any death, stroke, or serious adverse events related to rhythm-control therapy. Here we present the results of these outcomes in patients with a history of stroke. Analyses were done in the intention-to-treat population. EAST-AFNET 4 is registered with ClinicalTrials.gov (NCT01288352), EudraCT (2010-021258-20), and ISRCTN (ISRCTN04708680). FINDINGS: Between July 28, 2011, and Dec 30, 2016, 2789 patients were randomly assigned in the EAST-AFNET 4 trial to either early rhythm control (n=1395) or usual care (n=1394). Of these patients, five had no information on history of stroke and were excluded from this subgroup analysis. 217 (8%) patients had a history of stroke, of whom 110 were assigned to early rhythm control and 107 to usual care. The median age of participants with a history of stroke was 72·0 years (IQR 66·0-76·0). 95 (44%) participants were female and 122 (56%) were male. During a median follow-up of 4·7 years (3·5-6·4) for patients with a history of stroke, a first primary outcome event occurred in 18 (16%) of 110 patients in the early rhythm-control group (3·7 per 100 person-years) and 33 (31%) of 107 in the usual care group (7·4 per 100 person-years; hazard ratio [HR] 0·52, 95% CI 0·29-0·93). The mean number of nights spent in hospital per year was 5·1 (SD 13·2) for patients with a history of stroke assigned to early rhythm control and 6·6 (10·1) for those assigned to usual care (incidence rate ratio 0·87, 95% CI 0·55-1·38). Among patients with a history of stroke, primary safety events occurred in 17 (15%) patients in the early rhythm-control group versus 30 (28%) in the usual care group. INTERPRETATION: In this prespecified subgroup analysis in patients with recently diagnosed atrial fibrillation and a history of stroke, the effects of early rhythm control were consistent with the findings of the primary analysis. As the evidence from this subgroup analysis is considered supportive and exploratory, further research is needed to confirm the safety and efficacy of this approach in patients with a history of stroke.

A novel saline-based occlusion tool allows for dye-less cryoballoon-based pulmonary vein isolation and fluoroscopy reduction.

Background: Cryoballoon (CB)- based pulmonary vein isolation (PVI) remains guided by fluoroscopy and dye. The novel saline injection-based occlusion tool allows for pulmonary vein (PV)-occlusion assessment without the need for dye injection. Aim: To compare KODEX-EPD guided CB-PVI using the novel saline injection-based workflow with conventional cryoablation for acute efficacy, fluoroscopy exposure and dye volume. Methods: Consecutive atrial fibrillation (AF)- patients undergoing CB-PVI in conjunction with KODEX-EPD (CryoEPD group) were analyzed. Patients undergoing conventional CB-PVI (Cryo group) in the same time period acted as controls. Results: One hundred forty patients [91/140 (65%) persistent AF] were studied. Seventy patients underwent CryoEPD procedures [64 ± 13 years, 21 (30%) female] and seventy patients underwent Cryo procedures [68 ± 10 years, 27 (39%) female].A total of 560 PVs were identified and successfully isolated. Mean procedure time was 66 ± 15 min for the CryoEPD group, and 65 ± 19 min for the Cryo group (p = 0.3). Fluoroscopy time (CryoEPD 6 ± 4 min; Cryo 13 ± 6 min, p < 0.001) and dose area product (CryoEPD 193 [111; 297] cGycm2; Cryo 381 [268; 614] cGycm2, p < 0.001) were lower in patients undergoing CryoEPD compared with Cryo procedures. No dye was needed in the CryoEPD group while 53 ± 18 ml dye per patient were administered for the Cryo group (p < 0.001). The overall complication rate was comparable between both groups (p = 0.5). Conclusion: KODEX-EPD guided AF-ablation enables dye-free CB-based PVI with reduced fluoroscopy exposure when compared to conventional CB-ablation, without differences in acute procedural outcomes or procedure duration.

Coffee consumption and associations with blood pressure, LDL-cholesterol and echocardiographic measures in the general population.

Coffee, next to water the most widespread beverage, is attributed both harmful and protective characteristics concerning cardiovascular health. This study aimed to evaluate associations of coffee consumption with cardiac biomarkers, echocardiographic, electrocardiographic parameters and major cardiovascular diseases. We performed a cross-sectional analysis of 9009 participants of the population-based Hamburg City Health Study (HCHS), enrolled between 2016 and 2018 median age 63 [IQR: 55; 69] years. Coffee consumption was classified into three groups: < 3 cups/day (low), 3-4 cups/day (moderate), > 4 cups/day (high). In linear regression analyses adjusted for age, sex, body mass index, diabetes, hypertension, smoking, and additives, high coffee consumption correlated with higher LDL-cholesterol (ß = 5.92; 95% CI 2.95, 8.89; p < 0.001). Moderate and high coffee consumption correlated with lower systolic (ß = - 1.91; 95% CI - 3.04, - 0.78; p = 0.001; high: ß = - 3.06; 95% CI - 4.69, - 1.44; p < 0.001) and diastolic blood pressure (ß = - 1.05; 95% CI - 1.67, - 0.43; p = 0.001; high: ß = - 1.85; 95% CI - 2.74, - 0.96; p < 0.001). Different levels of coffee consumption did neither correlate with any investigated electrocardiographic or echocardiographic parameter nor with prevalent major cardiovascular diseases, including prior myocardial infarction and heart failure. In this cross-sectional analysis, high coffee consumption correlated with raised LDL-cholesterol levels and lower systolic and diastolic blood pressure. However, major cardiovascular diseases including heart failure and its diagnostic precursors were not associated with coffee consumption, connoting a neutral role of coffee in the context of cardiovascular health.
