- P2Y12 Inhibitor Pretreatment in Non-ST-Segment Elevation Acute Coronary Syndromes Undergoing a Late Invasive Strategy—A Portuguese Multicenter Nationwide Registry AnalysisPublication . Vazão, Adriana; Gonçalves, Carolina; Martins, André; Carvalho, Mariana; Cabral, Margarida; Santos, Luís; Pernencar, Sidarth; Carvalho, João; Morais, João; Riordan, Stephen; Wang, DongBackground/Objectives: Current guidelines do not specifically address the use of P2Y12 inhibitor (P2Y12i) pretreatment in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) who are expected to undergo a late invasive strategy. Nevertheless, such pretreatment may be considered in patients without a high bleeding risk (Class of Recommendation, IIb; Level of Evidence, C). Despite this ambiguity, P2Y12i pretreatment remains a common clinical practice. The present study aimed to evaluate the in-hospital prognostic impact of P2Y12i treatment prior to coronary angiography (CAG) in NSTE-ACS patients undergoing a late invasive strategy (CAG > 24 h after hospital admission). Methods: A retrospective analysis was conducted on NSTE-ACS patients undergoing a late invasive strategy included in the Portuguese Registry on Acute Coronary Syndromes between 2010 and 2023. The primary endpoint was a composite of in-hospital events, including all-cause mortality, non-fatal re-infarction, non-fatal stroke, and heart failure (HF). Secondary endpoints included the individual components of the primary endpoint and major bleeding (BARC types 3 and 4). Results: A total of 3776 patients were included (mean age, 66 ± 12 yrs; 29% female), of whom 1530 (41%) received P2Y12i pretreatment (group 1). Group 1 had a lower prevalence of prior myocardial infarction (16% vs. 21%) and prior percutaneous coronary intervention (12% vs. 15%) (both p ≤ 0.001). Although obstructive coronary artery disease was more frequent in group 1 (84% vs. 77%, p < 0.001), the presence of multivessel disease did not differ (52% vs. 52%, p = 0.667). Considering in-hospital antithrombotic therapy, group 1 had higher prescriptions of clopidogrel (68% vs. 56%), aspirin (99% vs. 81%), unfractionated heparin (21% vs. 8%), and enoxaparin (80% vs. 56%) (all p < 0.001). There was no significant difference in the primary composite endpoint between groups (9% vs. 9%, p = 0.906). Similarly, the secondary endpoints of all-cause mortality (0.6% vs. 0.7%), re-infarction (1.3% vs. 0.7%), stroke (0.7% vs. 0.4%), and HF (7% vs. 8%) did not differ significantly between groups (all p > 0.05). Nevertheless, group 1 exhibited higher rates of major bleeding (0.8 vs. 0.2%, OR 3.48, CI 95% 1.22–9.89, p = 0.013). Conclusions: Pretreatment with a P2Y12i in NSTE-ACS patients undergoing a late invasive strategy was not associated with reduction in the primary endpoint, although it was associated with higher rates of major bleeding.
- Sex-related differences in ST-segment elevation myocardial infarction: A Portuguese multicenter national registry analysisPublication . Gonçalves, Carolina Miguel; Carvalho, Mariana; Vazão, Adriana; Cabral, Margarida; Martins, André; Saraiva, Fátima; Morais, João; Oliveira, MárioIntroduction and objectives Sex differences among patients with acute myocardial infarctions remain a matter of debate. Inequalities in presentation, diagnosis, treatment, and prognosis are frequently observed, contributing to a worse prognosis in women. The aim of this study was to investigate sex-related differences in Portuguese ST-segment elevation myocardial infarction (STEMI) patients. Methods The authors conducted a retrospective analysis of STEMI patients included in the Portuguese Registry on Acute Coronary Syndromes, between October 2010 and 2022. The two co-primary endpoints were in-hospital and one-year mortality. Results A total of 14 470 STEMI patients were studied. Women were underrepresented with 3721 individuals (25.7%). They were significantly older (70 vs. 62 years, p<0.001), with higher prevalence of cardiovascular risk factors, and underwent less frequently coronary angiography (84.4% vs. 88.5%, p<0.001) and guideline-directed medical therapy (e.g., aspirin 92.5% vs. 95.4%, beta blockers 79.2% vs. 83%, p<0.001). Furthermore, they experienced more complications, such as congestive heart failure (23.4% vs. 14.6%), ischemic stroke (47% vs. 40%), and in-hospital mortality (8.5% vs. 4.1%) (p<0.001 for all comparisons). Similarly, they presented higher one-year mortality (11.5% vs. 6.3%, p<0.001). However, after a multivariate analysis testing significant clinical variables, female sex remained an independent predictor for in-hospital (odds ratio=1.633; 95% CI [1.065–2.504]; p=0.025), but not for one-year mortality. Conclusions This analysis reveals sex-related disparities in Portuguese STEMI patients. Despite limitations inherent to registry-based analysis, women were significantly older, with increased cardiovascular risk, less treated, and with higher in-hospital mortality. These disparities should be a concern for clinicians to further improve outcomes and move toward equitable medical care.
- Sudden cardiac death in athletes: A 20-year analysis in PortugalPublication . Gonçalves, Carolina Miguel; Vazão, Adriana; Carvalho, Mariana; Cabral, Margarida; Martins, André; Martins, Hélia; Saraiva, Fátima; Morais, João; Dores, HélderIntroduction and objectives Sudden cardiac death (SCD) in athletes is a tragic event, with some evidence remaining controversial. The aim of this study was to evaluate cases of SCD in athletes in Portugal within the last 20 years. Methods An advanced Google search using a combination of several keywords and systematic searches on websites of national newspapers/television stations was conducted. Additionally, 54 Portuguese sports federations and the Portuguese Institute of Sports and Youth were contacted by email and/or phone. All sports-related SCD cases in competitive athletes, occurring between 2003 and 2023 in Portugal, were included. The total number of athletes at risk used for the calculation of SCD incidence, was collected from official national records. Results A total of 42 SCD cases in athletes were identified, with a median age of 27 [18;42] years, and the great majority were male (n=39; 93%). Most events occurred in outdoor sports (n=28; 67%), especially in football (n=13; 31%), athletics (n=4; 10%) and trail running (n=4; 10%), and during competition or training sessions (n=27; 64%). The higher number of cases were reported in 2021 and 2022, while in several years no occurrences were found. The yearly average SCD incidence was 0.39 cases per 100 000 athletes/year. Conclusions The incidence of SCD in athletes in Portugal is very low, mainly occurring in male, outdoor sports and during competitions or training sessions. Due to the limitations of passive data collection, prospective registries are needed, with standardization of the most relevant data, especially regarding their etiology and circumstances.
