Educational status and the risk of adverse outcomes in Asian patients with atrial fibrillation: a report from the prospective APHRS-AF Registry.

BACKGROUND: The aim of this study was to evaluate the impact of educational status (ES) on the clinical course of Asian patients with atrial fibrillation (AF). METHODS: We used data from the prospective APHRS-AF Registry. ES was classified as follows: low (primary school), medium (secondary), and high (University). The primary outcome was a composite of all-cause death, thromboembolic events, acute coronary syndrome, and heart failure. Secondary outcomes were each component of the primary outcome, cardiovascular death, and major bleeding. The one-year risk of primary and secondary outcomes was assessed through Cox-regressions. Adherence to the Atrial fibrillation Better Care (ABC) pathway was assessed. RESULTS: Among 2697 AF patients (69±12 years, 34.8% females), 34.6% had low ES; 37.3% had medium ES; and 28.1% had high ES. Compared to patients with medium-high ES, patients with low ES were older, more often females, with a higher prevalence of cardiovascular risk factors, and a lower ABC pathway adherence (30.4% vs. 40.2%, P<0.001). On multivariable analysis, low ES was associated with a higher risk for the primary outcome (HR 1.52,95%CI 1.11-2.06) and all-cause death (HR 1.76,95%CI 1.10-2.83) than medium-high ES. A significant interaction was found for the risk of composite outcome among the different age strata, with the higher risk in the elderly (P for int=0.008), whereas the beneficial effect of the ABC pathway was irrespective of ES (P for int=0.691). CONCLUSIONS: In Asian AF patients, low ES is associated with high mortality. Efforts to improve education and include ES evaluation in the integrated care approach for AF are necessary to reduce the cardiovascular burden in these patients.

Adverse Events and Clinical Correlates in Asian Patients with Atrial Fibrillation and Diabetes Mellitus: A Report from Asia Pacific Heart Rhythm Society Atrial Fibrillation Registry.

Aims. To evaluate the adverse events (and its clinical correlates) in a large prospective cohort of Asian patients with atrial fibrillation (AF) and diabetes mellitus (DM). Material and Methods. We recruited patients with atrial fibrillation (AF) from the Asia-Pacific Heart Rhythm Society (APHRS) AF Registry and included those for whom the diabetic mellitus (DM) status was known. We used Cox-regression analysis to assess the 1-year risk of all-cause death, thromboembolic events, acute coronary syndrome, heart failure and major bleeding. Results. Of 4058 patients (mean age 68.5 ± 11.8 years; 34.4% females) considered for this analysis, 999 (24.6%) had DM (age 71 ± 11 years, 36.4% females). Patients with DM had higher mean CHA2DS2-VASc (2.3 ± 1.6 vs. 4.0 ± 1.5, p < 0.001) and HAS-BLED (1.3 ± 1.0 vs. 1.7 ± 1.1, p < 0.001) risk scores and were less treated with rhythm control strategies compared to patients without DM (18.7% vs. 22.0%). After 1-year of follow-up, patients with DM had higher incidence of all-cause death (4.9% vs. 2.3%, p < 0.001), cardiovascular death (1.3% vs. 0.4%, p = 0.003), and major bleeding (1.8% vs. 0.9%, p = 0.002) compared to those without DM. On Cox regression analysis, adjusted for age, sex, heart failure, coronary and peripheral artery diseases and previous thromboembolic event, DM was independently associated with a higher risk of all-cause death (HR 1.48, 95% CI 1.00-2.19), cardiovascular death (HR 2.33, 95% CI 1.01-5.40), and major bleeding (HR 1.91, 95% 1.01-3.60). On interaction analysis, the impact of DM in determining the risk of all-cause death was greater in young than in older patients (p int = 0.010). Conclusions. Given the high rates of adverse outcomes in these Asian AF patients with DM, efforts to optimize the management approach of these high-risk patients in a holistic or integrated care approach are needed.

Risk of Death and Cardiovascular Events in Asian Patients With Atrial Fibrillation and Chronic Obstructive Pulmonary Disease: A Report From the Prospective APHRS Registry.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is associated with an increased risk of adverse events in patients with atrial fibrillation (AF); however, few data are available on this topic in Asian populations. METHODS AND RESULTS: Prospective observational study conducted on patients with AF enrolled in the Asia-Pacific Heart Rhythm Society (APHRS) AF Registry. The diagnosis of COPD was based on data reported in the case report form by the investigators. Cox-regression models were used to assess the 1-year risk of a primary composite outcome of all-cause death, thromboembolic events, acute coronary syndrome, and heart failure. Analysis on single outcomes and cardiovascular death was also performed. Interaction analysis was used to assess the risk of composite outcome and all-cause death in different subgroups. The study included 4094 patients with AF (mean±SD age 68.5±12 years, 34.6% female), of whom 112 (2.7%) had COPD. Patients with COPD showed a higher incidence of the primary composite outcome (25.1% versus 6.3%, P<0.001), all-cause death (14.9% versus 2.6%, P<0.001), cardiovascular death (2.0% versus 0.6%, P<0.001), and heart failure (8.3% versus 6.0%, P<0.001). On multiple Cox-regression analysis, COPD was associated with a higher risk of the primary composite outcome (hazard ratio [HR], 3.17 [95% CI, 2.05-4.90]), all-cause death (HR, 3.59 [95% CI, 2.04-6.30]), and heart failure (HR, 3.32 [95% CI, 1.56-7.03]); no statistically significant differences were found for other outcomes. The association between COPD and mortality was significantly modified by the use of beta blockers (Pint=0.018). CONCLUSIONS: In Asian patients with AF, COPD is associated with worse prognosis. In patients with AF and COPD, the use of beta blockers was associated with a lower mortality. REGISTRATION INFORMATION: clinicaltrials.gov Identifier: NCT04807049.

External Validation of COOL-AF Scores in the Asian Pacific Heart Rhythm Society Atrial Fibrillation Registry.

Background: The COOL-AF (Cohort of Antithrombotic Use and Optimal International Normalized Ratio Levels in Patients with Atrial Fibrillation) risk scores for death, bleeding, and thromboembolic events (TEs) were derived from the COOL-AF cohort from Thailand and require external validation. Objectives: The authors sought to externally validate the COOL-AF scores in the APHRS (Asia-Pacific Heart Rhythm Society) registry and to compare their performance in the ESC-EHRA (European Society of Cardiology-European Heart Rhythm Association) EORP-AF (EURObservational Research Programme in Atrial Fibrillation) General Long-Term Registry. Methods: We studied 3,628 APHRS and 8,825 EORP-AF patients. Receiver operating characteristic (ROC) curves and Cox regression analyses were used to test the predictive value of COOL-AF scores and to compared them with the CHA2DS2-VASc and HAS-BLED scores. Results: Patients in the EORP-AF were older, had a higher prevalence of male sex, and were at higher thromboembolic and hemorrhagic risk than APHRS patients. After 1 year of follow-up in APHRS and EORP-AF, the following events were recorded: 87 (2.4%) and 435 (4.9%) death for any causes, 37 (1.0%) and 111 (1.3%) major bleeding, and 25 (0.7%) and 109 (1.2%) TEs, respectively. In APHRS, the COOL-AF scores showed moderate-to-good predictive value for all-cause mortality (area under the curve [AUC]: 0.77; 95% CI: 0.71-0.83), major bleeding (AUC: 0.68; 95% CI: 0.60-0.76), and TEs (AUC: 0.61; 95% CI: 0.51-0.71), and were similar to the CHA2DS2-VASc and HAS-BLED scores. In EORP-AF, the predictive value of COOL-AF for all-cause mortality (AUC: 0.68; 95% CI: 0.65-0.70) and major bleeding (AUC: 0.61; 95% CI: 0.60-0.62) was modest and lower than in APHRS. In EORP-AF, the COOL-AF score for TE was inferior to the CHA2DS2-VASc score. Conclusions: The COOL-AF risk scores may be an easy tool to identify Asian patients with AF at risk for death and major bleeding and performs better in Asian than in European patients with AF.

Left ventricular hypertrophy and mortality in ethnic minority groups in the UK: e-ECHOES study.

OBJECTIVES: Hypertension is the key modifiable cardiovascular risk factor but is underdiagnosed, and its scale in South Asian and African-Caribbean communities is unknown. Left ventricular hypertrophy (LVH) is a measure of target organ damage in uncontrolled hypertension. The study assesses LVH prevalence in South Asian and African-Caribbean communities and its impact on mortality. METHOD: This study is based on the large prospective UK community Ethnic-Echocardiographic Heart of England Screening Study (E-ECHOES, age ≥45 years). Left ventricular mass index (LVMI) was calculated using echocardiography to establish LVH. The predictive value of LVH all-cause and cardiovascular mortality was assessed using Cox regression. RESULTS: The study included 3200 South Asians (age 59 ±â€Š10 years, 52% women, 45% had a history of hypertension, 5.8 ±â€Š1.0-year follow-up). LVH was found in 1568 (49%), of whom 45% did not have hypertension diagnosis. On Cox regression, LVH was independently associated with all-cause mortality [hazard ratio 1.38, 95% confidence interval (95% CI) 1.01-1.88], cardiovascular mortality (hazard ratio 2.64, 95% CI 1.21-3.73). The projected overall hypertension prevalence was 82%, undiagnosed hypertension prevalence 37%. The study included 1858 African-Caribbeans (age 62 ±â€Š12, 45% women, 45% had history of hypertension, 5.1 ±â€Š0.9-year follow-up). LVH was found in 1186 (64%), of whom 32% did not have hypertension diagnosis. LVH was borderline associated with all-cause mortality (hazard ratio 1.57, 95% CI 1.01-2.44), but not cardiovascular mortality (hazard ratio 1.82, 95% CI 0.80-4.16). The projected overall hypertension prevalence was 78.5%, and undiagnosed hypertension prevalence was 20.8%. CONCLUSION: UK South Asians and African-Caribbeans have a high prevalence of hypertension, which is often underdiagnosed and poorly controlled.

Sex-related differences in presentation, treatment, and outcomes of Asian patients with atrial fibrillation: a report from the prospective APHRS-AF Registry.

We aimed to investigate the sex-related differences in the clinical course of patients with Atrial Fibrillation (AF) enrolled in the Asia-Pacific-Heart-Rhythm-Society Registry. Logistic regression was utilized to investigate the relationship between sex and oral anticoagulant, rhythm control strategies and the 1-year chance to maintain sinus rhythm. Cox-regression was utilized to assess the 1-year risk of all-cause, and cardiovascular death, thromboembolic events, acute coronary syndrome, heart failure, and major bleeding. In the whole cohort (4121 patients, 69 ± 12 years,34.3% female), females had different cardiovascular risk factors, clinical manifestations, and disease perceptions than men, with more advanced age (72 ± 11 vs 67 ± 12 years, p < 0.001) and dyslipidemia (36.7% vs 41.7%, p = 0.002). Coronary artery disease was more prevalent in males (21.1% vs 16.1%, p < 0.001) as well as the use of antiplatelet drugs. Females had a higher use of oral anticoagulant (84.9% vs 81.3%, p = 0.004) but this difference was non-significant after adjustment for confounders. On multivariable analyses, females were less often treated with rhythm control strategies (Odds Ratio [OR] 0.44,95% Confidence Interval [CI] 0.38-0.51) and were less likely to maintain sinus rhythm (OR 0.27, 95% CI 0.22-0.34) compared to males. Cox-regressions analysis showed no sex-related differences for the risk of death, cardiovascular, and bleeding. The clinical management of Asian AF patients should consider several sex-related differences.

Integrated Care for Atrial Fibrillation Using the ABC Pathway in the Prospective APHRS-AF Registry.

Background: The Atrial Fibrillation Better Care (ABC) has been proposed as an integrated approach to improve management in patients with atrial fibrillation (AF), based on 3 pillars: "A" Avoid stroke with Anticoagulation; "B" Better symptoms control; "C" Cardiovascular risk-factor and comorbidities management. Objectives: This study sought to investigate the association with outcomes of ABC adherence in the prospective multinational Asia-Pacific Heart Rhythm Society (APHRS) Atrial Fibrillation registry. Method: Cox-regression analyses adjusted for age, sex, CHA2DS2-VASc score, paroxysmal AF, chronic obstructive pulmonary disease, chronic kidney disease, cancer, dyslipidemia, and dementia were performed to investigate the association with outcomes. Primary outcome was a composite of all-cause death, any thromboembolic events, acute coronary syndrome or percutaneous interventional procedures, and advancing heart failure. Results: Of the 4,013 included patients with AF (mean age 68 ± 12 years; 34.4% female); 38.6% were adherent to all 3 main ABC pillars. After 1 year of follow-up, adherence to the ABC pathway was associated with a low incidence of composite outcome (4.0% vs 8.5%, P < 0.001), all-cause and cardiovascular death, and advancing heart failure. On Cox regression analysis, ABC adherence was associated with a lower risk of primary outcome (HR: 0.72; 95% CI: 0.53-0.97), with risk reduction progressively higher with a higher number of ABC criteria attained. No significant interaction in the association was seen according to the different geographic areas (Pint = 0.217). Conclusions: In a large contemporary cohort of Asian patients with AF, adherence to ABC pathway was associated with a reduction of the risk for adverse outcomes.

Antihypertensive treatment in people of very old age with frailty: time for a paradigm shift?

The optimal management of hypertension in individuals aged 80 years or older with frailty remains uncertain due to multiple gaps in evidence. Complex health issues, polypharmacy, and limited physiological reserve make responding to antihypertensive treatments unpredictable. Patients in this age group may have limited life expectancy, so their quality of life should be prioritized when making treatment decisions. Further research is needed to identify which patients would benefit from more relaxed blood pressure targets and which antihypertensive medications are preferable or should be avoided. A paradigm shift is required in attitudes towards treatment, placing equal emphasis on deprescribing and prescribing when optimizing care. This review discusses the current evidence on managing hypertension in individuals aged 80 years or older with frailty, but further research is essential to address the gaps in knowledge and improve the care of this population.

20 years on - the measurement of blood pressure and detection of hypertension in children and adolescents: a national descriptive survey.

In 1997 a survey identified a general lack of standardisation of blood pressure (BP) measurement and little consensus on the criteria for diagnosing hypertension amongst paediatricians. We have conducted a new online survey in 2021, to compare clinical practice between the two time periods. A national quality improvement survey was approved by the GAPRUKI committee and then circulated to consultant-grade general paediatricians. 125 analysable replies from 34 different sites were received and compared with the 1997 data. 106 (84.8%) reported clinic nurse involvement in BP measurement, more than twice than reported previously (40.6%). Most paediatricians (53.6%) now rely on oscillometric devices, whereas the mercury sphygmomanometer was favoured previously (82.7%). If assessing BP manually (n = 89), most (79.8%) now use Korotkoff phase V as the auscultatory endpoint for diastolic BP (phase IV was previously used (52.1%)). Diagnostic criteria of hypertension, the criteria (≥95th centile for gender, age and height) were constant, and 100% of paediatricians diagnosed it using systolic BP, but only 43 (34.4%) used diastolic BP, a decrease from 79.4% previously. Ambulatory BP Monitoring was six times more available than in 1997 (81.6% vs 13.6%). Similar to previous findings, only 12 (9.6%) paediatricians would manage hypertensive patients themselves, however 82 (72.6%) would keep general paediatric input. There have been important changes in the assessment of BP in children, including increased nurse involvement and greater use of technology. However, fewer paediatricians are responding to high diastolic pressures than twenty years ago.

Clinical implications of different types of dementia in patients with atrial fibrillation: Insights from a global federated health network analysis.

BACKGROUND: Atrial fibrillation (AF) associates with higher Alzheimer's disease (AD) and vascular dementia risks but the clinical implications have been scarcely investigated. We examined the association between AD or vascular dementia and adverse outcomes in AF patients. METHODS: Cohort study between January 2000 and 2017. AF patients were divided into two groups according to vascular dementia or AD, and balanced using propensity score matching (PSM). During 4-years of follow-up, incident intracranial hemorrhages (ICH), the composite of ischemic stroke/transient ischemic attack (TIA), hospitalizations, and all-cause deaths, were recorded. RESULTS: Two thousand three hundred seventy-seven AF patients with dementia (1225 with vascular dementia, and 1152 with AD) were identified. Following a PSM, 615 patients were included in each cohort (i.e., 1:1) and all variables were well-matched. After PSM, 22 (3.6%) patients with vascular dementia and 55 (8.1%) patients with AD had incident ICH during follow-up (hazard ratio [HR]: 2.22, 95% confidence interval [CI]: 1.33-3.70, log-rank p = 0.002). Overall, 237 (38.5%) patients with vascular dementia and 193 (31.4%) patients with AD, developed an ischemic stroke/TIA. The risk of ischemic stroke/TIA was 1.32-fold higher in vascular dementia (HR: 1.32, 95% CI: 1.09-1.59, log-rank p = 0.003). The risk of rehospitalization (HR: 1.14, 95% CI: 1.01-1.31), and mortality (HR: 1.25, 95% CI: 1.01-1.58) were also higher among AF patients with vascular dementia compared to AD. CONCLUSIONS: The two forms of dementia in AF patients are associated with different prognosis, with AD being associated with a higher risk of ICH, and vascular dementia with a higher risk of stroke/TIA, hospitalization, and mortality.

Dynamic changes of monocytes subsets predict major adverse cardiovascular events and left ventricular function after STEMI.

We explored how dynamic changes in monocyte subset counts (as opposed to static values to specific time points), and their phagocytic and NFκB activity relate to major adverse cardiovascular events (MACE) and left ventricular ejection fraction (LVEF) in patients with ST-elevation myocardial infarction (STEMI). Changes in counts, phagocytic activity and intracellular levels of inhibitory κB kinase ß (IKKß) (a marker of NFκB activity) of monocyte subsets (CD14++CD16-CCR2+ [Mon1], CD14++CD16+CCR2+ [Mon2] and CD14+CD16++CCR2- [Mon3]) were measured by flow cytometry in patients with STEMI at baseline, and again after one week, two weeks, and one month. LVEF was measured by echocardiography at baseline and six months after STEMI. Baseline data included 245 patients (mean ± SD age 60 ± 12 years; 22% female), who were followed for a median of 46 (19-61) months. Multivariate Cox regression demonstrated that more prominent dynamic reduction in Mon2 by week 1 (n = 37) was independently associated with fewer MACE (HR 0.06, 95% CI 0.01-0.55, p = 0.01). Also, less prominent reduction in Mon2 at month 1 (n = 24) was independently predictive of 6-month LVEF. None of the other dynamic changes in monocyte subsets were associated with changes in survival from MACE. Neither phagocytic activity nor IKKß were associated with survival for each monocyte subset. We showed how distinct pattern of dynamic changes in Mon2 are related to both MACE risk and recovery of cardiac contractility. Further research is needed to understand the mechanism of the monocyte effect and possibilities of their pharmacological manipulation.

Hypertension in Turner syndrome: a review of proposed mechanisms, management and new directions.

Acquired cardiovascular diseases account for much of the increased risk of premature death in patients with Turner syndrome (TS). Hypertension is a major modifiable cardiovascular risk factor. It has a high prevalence in TS developing at an early age and thus leading to prolonged exposure to high blood pressure. The aetiology for hypertension in TS is largely unknown. It is likely multifactorial, and recent hypotheses include altered sympathetic tone, vasculopathy and endocrine factors. In this review article we aim to provide a comprehensive review of data on mechanisms of hypertension in TS and their implication for diagnostics and optimal choice of antihypertensive treatments. Ultimately this knowledge should help prevent hypertension-related complications, and improve quality of life and life expectancy for patients with TS.

Contemporary management of atrial fibrillation in primary and secondary care in the UK: the prospective long-term AF-GEN-UK Registry.

AIMS: This study established a prospective registry of contemporary management of UK patients with atrial fibrillation (AF) by cardiologists, general practitioners, and stroke, acute, and emergency medicine physicians at baseline and 1-year follow-up. METHODS AND RESULTS: Data on patients with recently diagnosed AF (≤12 months) were collected from medical records from 101 UK sites to permit comparison of patient characteristics and treatments between specialities. The impact of guideline-adherent oral anticoagulation (OAC) use on outcomes was assessed using Cox regression analysis. One thousand five hundred and ninety-five AF patients [mean (standard deviation) age 70.5 (11.2) years; 60.1% male; 97.4% white] were recruited in June 2017-June 2018 and followed up for 1 year. Overall OAC prescription rates were 84.2% at baseline and 87.1% at 1 year, with non-vitamin K antagonist oral anticoagulants (NOACs) predominating (74.9 and 79.2% at baseline and 1 year, respectively). Vitamin K antagonist prescription was significantly higher in primary care, with NOAC prescription higher among stroke physicians. Guideline-adherent OAC (CHA2DS2-VASc ≥2) at baseline significantly reduced risk of death and stroke at 1 year [adjusted hazard ratio (95% confidence interval): 0.48 (0.27-0.84) and 0.11 (0.02-0.48), respectively]. Rhythm control is evident in ∼25%; only 1.6% received catheter ablation. CONCLUSION: High OAC use (>80%, mainly NOACs) rates varied by speciality, with VKA prescription higher in primary care. Guideline-adherent OAC therapy at baseline was associated with significant reduction in death and stroke at 1 year, regardless of speciality. Rhythm-control management is evident in only one-quarter despite AF symptoms reported in 56.6%. This registry extends the knowledge of contemporary AF management outside cardiology and demonstrates good implementation of clinical guidelines for the management of AF, particularly for stroke prevention.

Altered cardiac and vascular stiffness in pregnancy after a hypertensive pregnancy.

Hypertensive disorders of pregnancy are an important cause of morbidity and mortality, impacting on both maternal and fetal wellbeing. Affected women are at higher risk of future cardiovascular morbidity and mortality. Our study objective was to assess differences in cardiovascular function in pregnant women previously affected by gestational hypertension or preeclampsia. Pregnant women diagnosed with gestational hypertension or preeclampsia in a previous pregnancy were recruited at the start of a subsequent pregnancy and compared to healthy pregnant and non-pregnant controls. All patients underwent pulse wave analysis and echocardiography. Indexes of echocardiography-derived arterial and left ventricular elastance were calculated. In our study women with prior hypertension (n = 25) were more likely to have blood pressure in the 120-139/80-99 mmHg (prehypertension) range. Women with previous hypertension in pregnancy had increased late diastolic transmitral flow velocities (A wave) and increased augmentation index. Women without prior hypertension (n = 50) demonstrated more compliance (reduced EaI and Ees) compared to the non-pregnant controls (n = 40). This adaptation was not seen in pregnancy with prior hypertension, where increased arterial stiffness was observed. In conclusion we have shown increased prevalence of prehypertension and increased arterial stiffness in pregnant women previously affected by gestational hypertensive disease. An increased atrial component to ventricular filling reflects altered diastolic function after hypertensive pregnancy. These women are at increased future cardiovascular risk due to altered cardiac and vascular function and require effective risk mitigation.

Outcome of Femoral Angioplasty/Stenting Procedures in Different Ethnic Groups in England: A Retrospective Analysis of Hospital Episode Statistics and Review of Literature.

PURPOSE: Various studies, mainly from North America, report worse outcomes in ethnic minority populations submitted to revascularization for peripheral arterial disease (PAD). Limited nationwide data in relation to ethnicity are available from Europe. OBJECTIVE: The objective of the study is to compare the outcomes of femoral angioplasty/stenting procedures among different ethnic groups in England during the 10-year period from 2006 to 2015. MATERIALS AND METHODS: The "Hospital Episode Statistics" database has been searched using International Classification of Diseases, Tenth Revision (ICD-10) codes to identify all cases of femoral angioplasty or stenting from English NHS Hospitals between January 1, 2006, and December 31, 2015. Subsequent mortality, second open or endovascular infrainguinal procedures, and major amputations on the same side within 2 years after the first procedure have been recorded. Patients were broadly categorized according to ethnicity as whites, Asians, and blacks. Chi-square test was used to demonstrate significant differences among ethnic groups and odds ratios (ORs) were calculated using white ethnic group as reference. RESULTS: A total number of 70 887 femoral endovascular procedures were recorded in patients from the 3 ethnic groups. Two-year mortality in whites, Asians, and blacks was 18.3%, 22.1%, and 19.5% (p<0.001); rates of second endovascular procedure were 12.1%, 13.1%, and 13.5% (p=0.24); rates of open infrainguinal procedure were 5.6%, 4.5%, and 8.0% (p<0.001); and rates of major amputation were 4.8%, 4.1%, and 7.0% (p<0.001), respectively. Mortality was higher in Asians (OR=1.26, 95% confidence interval [CI]=1.10-1.45, p<0.01) compared with whites. On the contrary, blacks underwent more open arterial operations (OR=1.48, 95% CI=1.19-1.83, p<0.01) and more amputations (OR=1.49, 95% CI=1.18-1.87, p<0.01). There were no significant differences in the rates of second endovascular procedures. CONCLUSION: Two-year mortality after femoral angioplasty/stenting is higher in Asians, whereas risk of limb loss is higher in blacks compared with whites. Reasons of these ethnic differences in outcomes following femoral endovascular procedures for PAD merit further study.

Saúde Cardiovascular e Fibrilação ou Flutter Atrial: Um Estudo Transversal do ELSA-Brasil / Cardiovascular Health and Atrial Fibrillation or Flutter: A Cross-Sectional Study from ELSA-Brasil

Resumo Fundamento A associação entre o status de saúde cardiovascular ideal ( ideal cardiovascular health ( ICVH) e diagnóstico de fibrilação ou flutter atrial (FFA) foi menos estudado em comparação a outras doenças cardiovasculares. Objetivos Analisar a associação entre o diagnóstico de FFA e métricas e escores de ICVH no Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil). Métodos Este estudo analisou dados de 13141 participantes com dados completos. Os traçados eletrocardiográficos foram codificados de acordo com o Sistema de Minnesota, em um centro de leitura centralizado. As métricas do ICVH (dieta, atividade física, índice de massa corporal, tabagismo, glicemia de jeju, e colesterol total) e escores do ICVH foram calculados conforme proposto pela American Heart Association . Modelos de regressão logística bruta e ajustada foram construídos para analisar associações de métricas e escores do ICVH com diagnóstico de FFA. O nível de significância foi estabelecido em 0,05. Resultados A idade mediana da amostra foi de 55 anos, e 54,4% eram mulheres. Nos modelos ajustados, os escores de ICVH não apresentaram associação significativa com diagnóstico de FFA prevalente [odds ratio (OR):0,96; intervalo de confiança de 95% (IC95%):0,80-1,16; p=0,70). Perfis de pressão arterial ideal (OR:0,33; IC95%:0,1-0,74; p=0,007) e colesterol total ideal (OR:1,88; IC95%:1,19-2,98; p=0,007) foram significativamente associados com o diagnóstico de FFA. Conclusões Não foram identificadas associações significativas entre escores de ICVH global e diagnóstico de FFA após ajuste multivariado em nossas análises, devido, ao menos em parte, às associações antagônicas da FFA com métricas de pressão arterial e de colesterol total do ICVH. Nossos resultados sugerem que estimar a prevenção da FFA por meio de escore de ICVH global pode não ser adequado, e as métricas do ICVH devem ser consideradas separadamente.

Abstract Background The association between ideal cardiovascular health (ICVH) status and atrial fibrillation or flutter (AFF) diagnosis has been less studied compared to other cardiovascular diseases. Objective To analyze the association between AFF diagnosis and ICVH metrics and scores in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Methods This study analyzed data from 13,141 participants with complete data. Electrocardiographic tracings were coded according to the Minnesota Coding System, in a centralized reading center. ICVH metrics (diet, physical activity, body mass index, smoking, blood pressure, fasting plasma glucose, and total cholesterol) and scores were calculated as proposed by the American Heart Association. Crude and adjusted binary logistic regression models were built to analyze the association of ICVH metrics and scores with AFF diagnosis. Significance level was set at 0.05. Results The sample had a median age of 55 years and 54.4% were women. In adjusted models, ICVH scores were not significantly associated with prevalent AFF diagnosis (odds ratio [OR]:0.96; 95% confidence interval [95% CI]:0.80-1.16; p=0.70). Ideal blood pressure (OR:0.33; 95% CI:0.15-0.74; p=0.007) and total cholesterol (OR:1.88; 95% CI:1.19-2.98; p=0.007) profiles were significantly associated with AFF diagnosis. Conclusions No significant associations were identified between global ICVH scores and AFF diagnosis after multivariable adjustment in our analyses, at least partially due to the antagonistic associations of AFF with blood pressure and total cholesterol ICVH metrics. Our results suggest that estimating the prevention of AFF burden using global ICVH scores may not be adequate, and ICVH metrics should be considered in separate.
