RESUMO
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.

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.
RESUMO
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.
RESUMO
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.

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.
RESUMO
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.

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.

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.
