RESUMEN
INTRODUCTION: The change in prevalence and management of chronic obstructive pulmonary disease (COPD) led to changes in outcomes and costs. We aimed to assess current clinical outcomes, resource utilization and costs in COPD. METHODS: Retrospective, observational study of a cohort of consecutive COPD patients who visited the emergency department (ED) of a large tertiary hospital in 2018. The study measured baseline characteristics, 30-day and 1-year mortality, readmission, re-ED visit rates, and costs using the Clinical Outcomes, Healthcare Resource Utilisation, and Related costs (COHERENT) model, validated for heart failure. This model, featuring a colour graphic system, tracks time spent in different clinical situations (home, ED, hospital), considering vital status, healthcare resource use, and related costs. RESULTS: In 2018, 2,384 patients with a primary COPD diagnosis visited the ED. The average age was 76 years, with 40% women. Observed mortality rates were 7.6% in-hospital, 8.5% at 30 days, and 23.4% at one year. The readmission rates were 9.9% and 36.1% respectively. The cohort's one-year cost was approximately 14.6 million ($15.95 million), with a median cost per patient of 3,298 ($3,603.96). Hospitalization incurred the highest costs, with initial hospitalization and readmissions accounting for 44.7% and 42.6% of expenditures, respectively. CONCLUSION: One-year mortality and readmission rates for patients with COPD visiting the ED remain high with a significant economic impact on the health system. This burden justifies special programs to improve their care.
RESUMEN
INTRODUCTION AND OBJECTIVES: Invasive management in frail patients with non-ST-segment elevation myocardial infarction (NSTEMI) remains controversial. We investigated the impact of various geriatric conditions. METHODS: The MOSCA-FRAIL trial included 167 adults aged ≥ 70 years with frailty (Clinical Frailty Scale [CFS] ≥ 4 points) and NSTEMI, who were randomized to either an invasive (n=84) or conservative (n=83) strategy. In addition to frailty, we measured activities of daily living (Barthel index), cognitive impairment (Pfeiffer test), and comorbidities (Charlson index). The primary endpoint was the difference (invasive minus conservative) in restricted mean survival time (RMST) for all-cause mortality at a median follow-up of 3.9 years. RESULTS: A total of 93 patients died. The RMST difference favored invasive management at the CFS 25th percentile (CFS=4; 157 days, 95%CI, 18-295; P=.027), which changed to a nonsignificant effect at the 50th and 75th percentiles. The RMST difference remained nonsignificant, irrespective of the severity of other geriatric assessments. In time-to-event analysis, invasive management was associated with an initially lower life expectancy, peaking at around 1 year, among all subgroups. However, patients with CFS=4 experienced a benefit at the end of follow-up (181 days, 95%CI, 19-343), whereas those with CFS >4 did not (-16 days, 95%CI, -217 to 186; interaction P=.16). Subgroups defined by other geriatric markers showed a similar time-dependent trend, albeit with weaker statistical interaction. CONCLUSIONS: Among adults with frailty and NSTEMI, the CFS might be useful for evaluating the relative risks and benefits of invasive management. A CFS >4 could serve as a valuable threshold for decision-making.
RESUMEN
Objective: This study aimed to determine the prevalence of non-adherence to preventive interventions, its clinical consequences, and factors associated with non-adherence to secondary prevention measures, with a special emphasis on sex and gender. Methods: Prospective observational study of patients hospitalized for acute myocardial infarction (AMI) in whom an evaluation of adherence to medication, Mediterranean diet, physical activity, and cardiac rehabilitation was performed after 6 and 12 months, with systematic assessment of predictors including patient-, disease-, psychological-, social-, and gender-related factors using self-administered questionnaires. Results: Of 503 patients included, 101 (20,1%) were females. At one year, 85% of patients did not adhere to at least one of the recommendations with no differences between females and males. However, two factors more frequent in females, caregiver burden (adjusted OR, 1.45; 95%CI, 1.08-1.94) and depressive symptoms (adjusted OR, 1.40; 95%CI, 1.03-1.92) predicted non-adherence to all measures together. Chronic kidney disease (aOR, 3.24; 95%CI, 1.02-10.48) and being female (aOR, 2.21; 95%CI, 1.18-4.13) were associated with non-adherence to the Mediterranean diet; diabetes with organ damage (aOR, 12.06; 95%CI, 1.93-7.69) and older age (aOR, 0.96 per year; 95%CI, 0.93-0.99), among others, with physical activity; and higher body mass index with cardiac rehabilitation participation (aOR, 1.07; 95%CI, 1.002-1.14) and completion (aOR, 1.14; 95%CI, 1.03-1.26). Conclusion: Adherence to all secondary prevention measures after AMI remains very low and is associated with several gender-related factors. Multidisciplinary intervention strategies targeting the most vulnerable patient groups, such as females or patients with diabetes, obesity, chronic kidney disease, or depression, are warranted.
RESUMEN
BACKGROUND: In patients with ischemic heart disease, coronary microvascular dysfunction is associated with cardiovascular risk factors and poor prognosis; however, data from healthy individuals are scarce. OBJECTIVES: The purpose of this study was to assess the impact of cardiovascular risk factors and subclinical atherosclerosis on coronary microvascular function in middle-aged asymptomatic individuals. METHODS: Myocardial perfusion was measured at rest and under stress using cardiac magnetic resonance in 453 individuals and used to generate myocardial blood flow (MBF) maps and calculate myocardial perfusion reserve (MPR). Subclinical atherosclerosis was assessed using 3-dimensional vascular ultrasound of the carotid and femoral arteries and coronary artery calcium scoring at baseline and at 3-year follow-up. RESULTS: Median participant age was 52.6 years (range: 48.9-55.8 years), and 84.5% were male. After adjusting for age and sex, rest MBF was directly associated with the number of the metabolic syndrome components present (elevated waist circumference, systolic and diastolic blood pressure, fasting glucose, and triglycerides and low high-density lipoprotein cholesterol), insulin resistance (homeostatic model assessment for insulin resistance), and presence of diabetes. MPR was reduced in the presence of several metabolic syndrome components, elevated homeostatic model assessment for insulin resistance, and diabetes. Stress MBF was inversely associated with coronary artery calcium presence and with global plaque burden. Higher stress MBF and MPR were associated with less atherosclerosis progression (increase in plaque volume) at 3 years. CONCLUSIONS: In asymptomatic middle-aged individuals free of known cardiovascular disease, the presence of cardiometabolic risk factors and systemic (poly-vascular) subclinical atherosclerosis are associated with impaired coronary microvascular function. Better coronary microvascular function reduces atherosclerosis progression at follow-up. (Progression of Early Subclinical Atherosclerosis [PESA]; NCT01410318).

BACKGROUND: Significant knowledge gaps remain regarding the heterogeneity of heart failure (HF) phenotypes, particularly among patients with preserved or mildly reduced left ventricular ejection fraction (HFp/mrEF). Our aim was to identify HF subtypes within the HFp/mrEF population. METHODS: K-prototypes clustering algorithm was used to identify different HF phenotypes in a cohort of 2 570 patients diagnosed with HFmrEF or HFpEF. This algorithm employs the k-means algorithm for quantitative variables and k-modes for qualitative variables. RESULTS: We identified three distinct phenotypic clusters: Cluster A (n = 850, 33.1%), characterized by a predominance of women with low comorbidity burden; Cluster B (n = 830, 32.3%), mainly women with diabetes mellitus and high comorbidity; and Cluster C (n = 890, 34.5%), primarily men with a history of active smoking and respiratory comorbidities. Significant differences were observed in baseline characteristics and one-year mortality rates across the clusters: 18% for Cluster A, 33% for Cluster B, and 26.4% for Cluster C (P < 0.001). Cluster B had the shortest median time to death (90 days), followed by Clusters C (99 days) and A (144 days) (P < 0.001). Stratified Cox regression analysis identified age, cancer, respiratory failure, and laboratory parameters as predictors of mortality. CONCLUSION: Cluster analysis identified three distinct phenotypes within the HFp/mrEF population, highlighting significant heterogeneity in clinical profiles and prognostic implications. Women were classified into two distinct phenotypes: low-risk women and diabetic women with high mortality rates, while men had a more uniform profile with a higher prevalence of respiratory disease.
RESUMEN
BACKGROUND: Older people less frequently receive invasive coronary angiography (ICA) for NSTEMI than younger patients. We describe care, ICA data, and in-hospital and 30-day outcomes of NSTEMI by age in a contemporary and geographically diverse cohort. METHODS: Prospective cohort study including 2947 patients with NSTEMI from 287 centres in 59 countries, stratified by age (≥75 years, n = 761). Quality of care was evaluated based on 12 guideline-recommended care interventions, and data collected on ICA. Outcomes included in hospital acute heart failure, cardiogenic shock, repeat myocardial infarction, stroke/transient ischaemic attack, BARC Type ≥3 bleeding and death, as well as 30-day mortality. RESULTS: Patients aged ≥75 years, compared with younger patients, at presentation had a higher prevalence of comorbidities and oral anticoagulation prescription (22.4% vs 7.6%, p < 0.001). Older patients less frequently received ICA than younger patients (78.6% vs 90.6%, p < 0.001) with the recorded reason more often being advanced age, comorbidities or frailty. Of those who underwent ICA, older patients more frequently demonstrated 3-vessel, 4-vessel and/or left main stem coronary artery disease compared to younger patients (49.7% vs 34.1%, p < 0.001) but less frequently received revascularisation (63.6% vs 76.9%, p < 0.001). Older patients experienced higher rates of in-hospital acute heart failure (15.0% vs 8.4%, p < 0.001) and bleeding (2.8% vs 1.3%, p = 0.006), as well as in-hospital and 30-day mortality (3.4% vs 1.3%, p < 0.001; 4.8% vs 1.7%, p < 0.001; respectively), than younger patients. CONCLUSIONS: Patients aged ≥75 years with NSTEMI, compared with younger patients, less frequently received ICA and guideline-recommended care, and had worse short-term outcomes.

Cardiovascular diseases (CVD) and diabetes pose significant health challenges in Europe, affecting millions and burdening healthcare systems. The recent EU4Health Programme places reducing the burden of non-communicable diseases (NCD) at the forefront, through a Joint Action focused on CVD and diabetes (JACARDI, Joint Action on CARdiovascular diseases and DIabetes). This initiative unites 21 European countries, including Ukraine, and over 300 experts. Employing an innovative approach and standardised methodology, JACARDI implements 142 pilot projects covering the entire "patient" journey. Particular focus will be given to improvement of data availability and quality. Additionally, JACARDI will emphasise transversal and intersectional aspects, such as health equity, determinants of health, and social, cultural, and ethnic diversity, while pioneering gender-transformative leadership. Committed to evidence-based interventions, JACARDI aims to harmonise strategies and disseminate knowledge for enhanced CVD and diabetes prevention and management. The goal is to identify effective strategies for wider implementation, fostering cross-national collaboration and fortifying Europe's health resilience.

Importance: The MOSCA-FRAIL randomized clinical trial compared invasive and conservative treatment strategies in patients with frailty with non-ST-segment elevation myocardial infarction (NSTEMI). It showed no differences in the number of days alive and out of the hospital at 1 year. Objective: To assess the outcomes of the MOSCA-FRAIL trial during extended follow-up. Design, Setting, and Participants: The MOSCA-FRAIL randomized clinical trial was conducted at 13 hospitals in Spain between July 7, 2017, and January 9, 2021, and included 167 adults (aged ≥70 years) with frailty (Clinical Frailty Scale score ≥4) and NSTEMI. In this preplanned secondary analysis, follow-up was extended to January 31, 2023. Data analysis was performed from April 5 to 29, 2023, using the intention-to-treat principle. Interventions: Patients were randomized to a routine invasive (coronary angiography and revascularization if feasible [n = 84]) or a conservative (medical treatment with coronary angiography only if recurrent ischemia [n = 83]) strategy. Main outcomes and measures: The primary end point was the difference in restricted mean survival time (RMST). Secondary end points included readmissions for any cause, considering recurrent readmissions. Results: Among the 167 patients included in the analysis, the mean (SD) age was 86 (5) years; 79 (47.3%) were men and 88 (52.7%) were women. A total of 93 deaths and 367 readmissions accrued. The RMST for all-cause death over the entire follow-up was 3.13 (95% CI, 2.72-3.60) years in the invasive and 3.06 (95% CI, 2.84-3.32) years in the conservative treatment groups. The RMST analysis showed inconclusive differences in survival time (invasive minus conservative difference, 28 [95% CI, -188 to 230] days). Patients under invasive treatment tended to have shorter survival in the first year (-28 [95% CI, -63 to 7] days), which improved after the first year (192 [95% CI, 90-230] days). Kaplan-Meier mortality curves intersected, displaying higher mortality to 1 year in the invasive group that shifted to a late benefit (landmark analysis hazard ratio, 0.58 [95% CI, 0.33-0.99]; P = .045). Early harm was more evident in the subgroup with a Clinical Frailty Scale score greater than 4. No differences were found for the secondary end points. Conclusions and Relevance: In this extended follow-up of a randomized clinical trial of patients with frailty and NSTEMI, an invasive treatment strategy did not improve outcomes at a median follow-up of 1113 (IQR, 443-1441) days. However, a differential distribution of deaths was observed, with early harm followed by later benefit. The phenomenon of depletion of susceptible patients may be responsible for this behavior.

AIMS: Evidence on the association between subclinical atherosclerosis (SA) and cardiovascular (CV) events in low-risk populations is scant. To study the association between SA burden and an ischaemic scar (IS), identified by cardiac magnetic resonance (CMR), as a surrogate of CV endpoint, in a low-risk population. METHODS AND RESULTS: A cohort of 712 asymptomatic middle-aged individuals from the Progression of Early SA (PESA-CNIC-Santander) study (median age 51 years, 84% male, median SCORE2 3.37) were evaluated on enrolment and at 3-year follow-up with 2D/3D vascular ultrasound (VUS) and coronary artery calcification scoring (CACS). A cardiac magnetic study (CMR) was subsequently performed and IS defined as the presence of subendocardial or transmural late gadolinium enhancement (LGE). On CMR, 132 (19.1%) participants had positive LGE, and IS was identified in 20 (2.9%) participants. Individuals with IS had significantly higher SCORE2 at baseline and higher CACS and peripheral SA burden (number of plaques by 2DVUS and plaque volume by 3DVUS) at both SA evaluations. High CACS and peripheral SA (number of plaques) burden were independently associated with the presence of IS, after adjusting for SCORE2 [OR for 3rd tertile, 8.31; 95% confidence interval (CI) 2.85-24.2; P < 0.001; and 2.77; 95% CI, 1.02-7.51; P = 0.045, respectively] and provided significant incremental diagnostic value over SCORE2. CONCLUSION: In a low-risk middle-aged population, SA burden (CAC and peripheral plaques) was independently associated with a higher prevalence of IS identified by CMR. These findings reinforce the value of SA evaluation to early implement preventive measures.

BACKGROUND AND AIMS: It is not well known if sex differences in the use and results of aortic valve replacement (AVR) are changing. The aim of the study is to assess the time trends in the differences by sex in the utilisation of AVR procedures in hospitals and in the community. METHODS: Retrospective observational analysis using data from the Spanish National Hospitalizations Administrative Database. All hospitalisations between 2016 and 2021 with a main diagnosis of aortic stenosis (ICD-10 codes: I35.0 and I35.2) were included. Time trends in hospitalisation, AVRs and hospital outcomes were analysed. Crude utilisation and population-standardised rates were calculated. RESULTS: During the study period, 64 384 hospitalisations in 55 983 patients (55.5% men) with 36 915 (65,9%) AVR were recorded. Of these, 15 563 (42.2%) were transcatheter and 21 432 (58.0%) surgical. At hospital level, transcatheter procedures were more frequently performed in women (32.3% vs 24.2%, p < 0.001) and surgical in men (42.9% vs. 32.5%, p < 0.001) but at the population level, surgical and transcatheter aortic valve replacements were used more frequently in men (12.6 surgical and 8.0 transcatheter per 100 000 population) vs women (6.4 and 5.8, respectively; p < 0.001 for both comparisons). Transcatheter procedures shifted from 17.3% in 2016 to 38.0% in 2021, overtaking surgical procedures in 2018 for women and 2021 for men. CONCLUSIONS: TAVR has displaced SAVR as the most frequent AVR procedure in Spain by 2020. This occurred earlier in women, who despite the greater weight of their age group in the older population, receive fewer AVRs, both SAVR and TAVR.
RESUMEN
AIM: Diabetes mellitus (diabetes) is common amongst patients with NSTEMI. We describe presentation, care and outcomes of patients admitted with NSTEMI by diabetes status. METHODS: Prospective cohort study including 2928 patients (1104 with prior diabetes, 1824 without) admitted to hospital with NSTEMI from 287 centres in 59 countries. Quality of care was evaluated based on 12 guideline-recommended care interventions. Outcomes included in-hospital acute heart failure, cardiogenic shock, repeat myocardial infarction, stroke/transient ischaemic attack (TIA), BARC Type ≥ 3 bleeding and death, as well as 30-day mortality. RESULTS: Patients with diabetes had higher comorbidity burden and more frequently presented with Killip Class II-IV heart failure (10.2% vs 3.7%, P < 0.001), haemodynamic instability (7.1% vs 3.7%, P < 0.001) and ongoing chest pain (43.1% vs 37.0%, P < 0.001), than those without diabetes. Overall, care quality received was similar by diabetes status (60.0% vs 60.5% received ≥ 80% of eligible care interventions, P = 0.786), but patients with diabetes experienced higher rates of in-hospital acute heart failure (15.3% vs 6.8% P < 0.001), cardiogenic shock (4.5% vs 2.5%, P = 0.002), stroke/TIA (2.0% vs 0.8%, P = 0.006) and death (2.5% vs 1.4%, P = 0.022), and higher 30-day mortality (3.3% vs 2.0%, P = 0.025). Of NSTEMI with diabetes, only 1.9% and 9.0% received prescription for GLP-1 RAs and SGLT2 inhibitors, respectively, on discharge, and only 45.9% were referred for cardiac rehabilitation. CONCLUSION: NSTEMI patients with diabetes, compared to those without, present more clinically unwell and have worse outcomes despite receiving equal quality of care. Prescription of cardiovascular-protective glycaemic agents is an actionable target to reduce risk of further events.
RESUMEN
OBJECTIVE: We aimed to evaluate the applicability of the eligibility criteria of randomized controlled trials (RCTs) cited in guideline recommendations in a real-world cohort of patients receiving secondary prevention after acute myocardial infarction from the EPICOR registries. METHODS: Recommendations provided by American and European guidelines for acute myocardial infarction were classified into general (applying to all patients) and specific (applying to patients with left ventricular dysfunction or heart failure). Randomized controlled trials cited in these recommendations were selected, and their entry criteria were applied to our international cohort of 18,117 patients. RESULTS: There were 91.5% patients eligible for beta blockers (84.6% for general, and 5.9% for specific recommendations), 97.7% eligible for renin-angiotensin system inhibitor (angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers [ACEI/ARB]) recommendations (69.9% for general, 27.9% for specific) and 4.1% eligible for mineralocorticoid receptor antagonists (only specific recommendations). The percentages of patients with eligibility criteria who were discharged with a prescription of the recommended therapies were 80%-85% for beta blockers, 70%-75% for ACEI/ARB, and 29% for mineralocorticoid receptor antagonists. There were large regional variations in the percentage of eligible patients and in those receiving the medications (eg, 95% in Northern Europe and 57% in Southeast Asia for beta blockers). CONCLUSION: Most real-world acute myocardial infarction patients are eligible for secondary prevention therapy in both general and specific guideline recommendations, and the percentage of those on beta blockers and ACEI/ARB at hospital discharge is high. There are large regional variations in the proportion of patients receiving recommended therapies. Local targeted interventions are needed for quality improvement.

AIMS: Women have historically been disadvantaged in terms of care and outcomes for non-ST-segment elevation myocardial infarction (NSTEMI). We describe patterns of presentation, care, and outcomes for NSTEMI by sex in a contemporary and geographically diverse cohort. METHODS AND RESULTS: Prospective cohort study including 2947 patients (907 women, 2040 men) with Type I NSTEMI from 287 centres in 59 countries, stratified by sex. Quality of care was evaluated based on 12 guideline-recommended care interventions. The all-or-none scoring composite performance measure was used to define receipt of optimal care. Outcomes included acute heart failure, cardiogenic shock, repeat myocardial infarction, stroke/transient ischaemic attack, BARC Type ≥3 bleeding, or death in-hospital, as well as 30-day mortality. Women admitted with NSTEMI were older, more comorbid, and more frequently categorized as at higher ischaemic (GRACE >140, 54.0% vs. 41.7%, P < 0.001) and bleeding (CRUSADE >40, 51.7% vs. 17.6%, P < 0.001) risk than men. Women less frequently received invasive coronary angiography (ICA; 83.0% vs. 89.5%, P < 0.001), smoking cessation advice (46.4% vs. 69.5%, P < 0.001), and P2Y12 inhibitor prescription at discharge (81.9% vs. 90.0%, P < 0.001). Non-receipt of ICA was more often due to frailty for women than men (16.7% vs. 7.8%, P = 0.010). At ICA, more women than men had non-obstructive coronary artery disease or angiographically normal arteries (15.8% vs. 6.3%, P < 0.001). Rates of in-hospital adverse outcomes and 30-day mortality were low and did not differ by sex. CONCLUSION: In contemporary practice, women presenting with NSTEMI, compared with men, less frequently receive antiplatelet prescription, smoking cessation advice, or are considered eligible for ICA.

BACKGROUND AND OBJECTIVES: Standardization of radiomic data acquisition protocols is still at a very early stage, revealing a strong need to work towards the definition of uniform image processing methodologies The aim of this study is to identify sources of variability in radiomic data derived from image discretization and resampling methodologies prior to image feature extraction. Furthermore, to identify robust potential image-based biomarkers for the early detection of cardiotoxicity. METHODS: Image post-acquisition processing, interpolation, and volume of interest (VOI) segmentation were performed. Four experiments were conducted to assess the reliability in terms of the intraclass correlation coefficient (ICC) of the radiomic features and the effects of the variation of voxel size and gray level discretization. Statistical analysis was performed separating the patients according to cardiotoxicity diagnosis. Differences of texture features were studied with Mann-Whitney U test. P-values <0.05 after multiple testing correction were considered statistically significant. Additionally, a non-supervised k-Means clustering algorithm was evaluated. RESULTS: The effect of the variation in the voxel size demonstrated a non-dependency relationship with the values of the radiomic features, regardless of the chosen discretization method. The median ICC values were 0.306 and 0.872 for absolute agreement and consistency, respectively, when varying the discretization bin number. The median ICC values were 0.678 and 0.878 for absolute agreement and consistency, respectively, when varying the discretization bin size. A total of 16 first order, 6 Gray Level Co-occurrence Matrix (GLCM), 4 Gray Level Dependence Matrix (GLDM) and 4 Gray Level Run Length Matrix (GLRLM) features demonstrated statistically significant differences between the diagnosis groups for interim scans (P<0.05) for the fixed bin size (FBS) discretization methodology. However, no statistically significant differences between diagnostic groups were found for the fixed bin number (FBN) discretization methodology. Two clusters based on the radiomic features were identified. CONCLUSIONS: Gray level discretization has a major impact on the repeatability of the radiomic features. The selection of the optimal processing methodology has led to the identification of texture-based patterns for the differentiation of early cardiac damage profiles.

OBJECTIVES: To determine the impact of risk stratification using the MEESSI-AHF (Multiple Estimation of risk based on the Emergency department Spanish Score In patients with acute heart failure) scale to guide disposition decision-making on the outcomes of ED patients with acute heart failure (AHF), and assess the adherence of emergency physicians to risk stratification recommendations. METHODS: This was a prospective quasi-experimental study (before/after design) conducted in eight Spanish EDs which consecutively enrolled adult patients with AHF. In the pre-implementation stage, the admit/discharge decision was performed entirely based on emergency physician judgement. During the post-implementation phase, emergency physicians were advised to 'discharge' patients classified by the MEESSI-AHF scale as low risk and 'admit' patients classified as increased risk. Nonetheless, the final decision was left to treating emergency physicians. The primary outcome was 30-day all-cause mortality. Secondary outcomes were days alive and out of hospital, in-hospital mortality and 30-day post-discharge combined adverse event (ED revisit, hospitalisation or death). RESULTS: The pre-implementation and post-implementation cohorts included 1589 and 1575 patients, respectively (median age 85 years, 56% females) with similar characteristics, and 30-day all-cause mortality was 9.4% and 9.7%, respectively (post-implementation HR=1.03, 95% CI=0.82 to 1.29). There were no differences in secondary outcomes or in the percentage of patients entirely managed in the ED without hospitalisation (direct discharge from the ED, 23.5% vs 24.4%, OR=1.05, 95% CI=0.89 to 1.24). Adjusted models did not change these results. Emergency physicians followed the MEESSI-AHF-based recommendation on patient disposition in 70.9% of cases (recommendation over-ruling: 29.1%). Physicians were more likely to over-rule the recommendation when 'discharge' was recommended (56.4%; main reason: need for hospitalisation for a second diagnosis) than when 'admit' was recommended (12.8%; main reason: no appreciation of severity of AHF decompensation by emergency physician), with an OR for over-ruling the 'discharge' compared with the 'admit' recommendation of 8.78 (95% CI=6.84 to 11.3). CONCLUSIONS: Implementing the MEESSI-AHF risk stratification tool in the ED to guide disposition decision-making did not improve patient outcomes.

BACKGROUND: Atherosclerosis is a systemic disease that frequently begins early in life. However, knowledge about the temporal disease dynamics (ie, progression or regression) of human subclinical atherosclerosis and their determinants is scarce. OBJECTIVES: This study sought to investigate early subclinical atherosclerosis disease dynamics within a cohort of middle-aged, asymptomatic individuals by using multiterritorial 3-dimensional vascular ultrasound (3DVUS) imaging. METHODS: A total of 3,471 participants from the PESA (Progression of Early Subclinical Atherosclerosis) cohort study (baseline age 40-55 years; 36% female) underwent 3 serial 3DVUS imaging assessments of peripheral arteries at 3-year intervals. Subclinical atherosclerosis was quantified as global plaque volume (mm3) (bilateral carotid and femoral plaque burden). Multivariable logistic regression models for progression and regression were developed using stepwise forward variable selection. RESULTS: Baseline to 6-year subclinical atherosclerosis progression occurred in 32.7% of the cohort (17.5% presenting with incident disease and 15.2% progressing from prevalent disease at enrollment). Regression was observed in 8.0% of those patients with baseline disease. The effects of higher low-density lipoprotein cholesterol (LDL-C) and elevated systolic blood pressure (SBP) on 6-year subclinical atherosclerosis progression risk were more pronounced among participants in the youngest age stratum (Pinteraction = 0.04 and 0.02, respectively). CONCLUSIONS: Over 6 years, subclinical atherosclerosis progressed in one-third of middle-age asymptomatic subjects. Atherosclerosis regression is possible in early stages of the disease. The impact of LDL-C and SBP on subclinical atherosclerosis progression was more pronounced in younger participants, a finding suggesting that the prevention of atherosclerosis and its progression could be enhanced by tighter risk factor control at younger ages, with a likely long-term impact on reducing the risk of clinical events.
