RESUMO
BACKGROUND: The safety and efficacy of treatment with P2Y12 adenosine-diphosphate receptor inhibitors (P2Y12-RI) before coronary angiography among patients with non-ST-segment elevation acute coronary syndromes (NSTEACS) are questionable. AIMS: To assess the pretreatment rate with P2Y12-RI and its association with ischemic and bleeding risks among patients with NSTEACS. METHODS: The study comprised patients with NSTEACS referred for coronary angiography and included in the Acute Coronary Syndrome Israeli Surveys between 2013 and 2021. Patients were divided into two groups according to the timing of P2Y12-RI loading concerning coronary angiography: pretreatment and posttreatment. The primary endpoints were 30-day major adverse cardiovascular events (MACE; composite of cardiovascular mortality, myocardial infarction, stroke, stent thrombosis, and urgent revascularization) and 1-year all-cause mortality. RESULTS: Of 3076 patients, 2423 (78.8%) received pretreatment with a P2Y12-RI, and 653 (21.2%) received P2Y12-RI posttreatment. Prasugrel and ticagrelor were used more in the posttreatment group compared to the pretreatment group (16% vs. 6% and 38% vs. 25%, respectively, p < 0.001 for both). No difference was observed in the rate of 30-day MACE comparing pretreatment and posttreatment (5.3% vs. 2.2%, respectively, p = 0.62). A sensitivity analysis of 30-day MACE among patients from the 2021 survey demonstrated similar results (2.5% in the posttreatment group vs. 8.0% in the pretreatment group, p = 0.13). There were no differences in 1-year all-cause mortality rates between the pretreatment and posttreatment groups (4.8% vs. 3.8%, p = 0.31). CONCLUSIONS: Among patients with NSTEACS referred for an invasive strategy, the P2Y12-RI posttreatment strategy was associated with similar 30-day and 1-year MACE as the pretreatment strategy. These large-scale, multicenter, real-world data provide reassurance on the safety and efficacy of delaying P2Y12-IR until after coronary stratification to improve clinical decision-making.
RESUMO
BACKGROUND: Management of cancer patients presenting with an acute coronary syndrome (ACS) may be challenging. In this study, we sought to examine whether and how a concomitant diagnosis of active cancer affects patients' management and outcomes following an event of ACS. METHODS: We used a retrospective cohort data analysis of patients from the Acute Coronary Syndrome Israeli Survey (ACSIS) carried out between the years 2016-2021 to compare patients with and without a concomitant diagnosis of active cancer. RESULTS: Of 4913 patients who presented with an ACS, 90 (1.8%) patients had a concomitant active cancer. Cancer patients were older, with a higher prevalence of hypertension and chronic renal failure. The rate of ST-elevation myocardial infarction (STEMI) was similar (40%) between both groups. Cancer patients were less likely to undergo coronary angiography during hospitalization; but once it was performed, the rate of percutaneous coronary intervention was similar. The presence of cancer during an ACS was associated with an increased short- and long-term mortality. In a multivariate analysis, the risk for 1-year mortality remained significantly higher in cancer patient (HR 2.72, 95% CI 1.74-4.24, p < 0.001), and was most prominent in patients presenting with STEMI (HR 5.00, 95% CI 2.40-10.39, p < 0.001). Short- and long-term death rates were also higher in cancer patients after a propensity score matching and adjustment for comorbidities other than cancer. CONCLUSION: Despite significant advances in oncologic and cardiac care, the presence of active cancer in patients with an ACS is still associated with significantly increased risk for 1-year mortality.
RESUMO
Introduction: Patients with ST-elevation myocardial infarction (STEMI) and late arrival (>12 h) after symptom onset, are at high risk for mortality and heart failure and represent a challenge for management. We aimed to define patient characteristics, management, and outcome of late-arrival STEMI in Israel over the last 20 years. Methods: We analyzed data of late-arrival STEMI (12-48 h and > 48 h) from the biennial acute coronary syndrome Israeli Surveys (ACSIS), as well as time-dependent changes [early (2000-2010) Vs. late (2013-2021) period]. Results: Data regarding time from symptom onset to hospital arrival was available in 6,466 STEMI patients. Of these, 9.6 % arrived 12-48 h and 3 % >48 h from symptom onset. Late-arrival patients were more likely to be older women with diabetes and high GRACE score and less likely to have prior myocardial infarction.In recent years, 95 % of patients arriving 12-48 h and 96 % of those arriving > 48 h had coronary angiography, as opposed to 75 % and 77 % in the early years (p = 0.007). Percutaneous coronary intervention (PCI) increased from 60 % and 55 % respectively to 85 % (p ≤ 0.001).TIMI-3 flow after primary PCI was 89-92 %, irrespective of arrival time. Late arrival patients (12-48 h but not > 48 h) who had PCI had better adjusted 1-year survival, HR 0.49 (95 %CI 0.29-0.82), p = 0.01. Conclusions: Late-arrival STEMI patients have higher risk characteristics. Most late-arrival patients undergo coronary angiography and PCI and have TIMI-3 flow after primary PCI. In patients arriving 12-48 h after symptom onset PCI is associated with better survival.
RESUMO
BACKGROUND: Bleeding is one of the most frequent complications in patients undergoing transcatheter aortic valve replacement (TAVR). Importantly, major bleeding is associated with poor clinical outcomes after TAVR. However, large studies on bleeding complications in the contemporary TAVR population are limited. OBJECTIVES: The aim of this study was to assess the incidence, temporal trends, clinical outcomes, and predictors of bleeding in patients undergoing transfemoral TAVR. METHODS: The CENTER2 study is a pooled patient-level database from 10 clinical studies including patients who underwent TAVR between 2007 and 2022. RESULTS: A total of 23,562 patients underwent transfemoral TAVR. The mean age was 81.5 ± 6.7 years, and 56% were women. Major bleeding within the first 30 days was observed in 1,545 patients (6.6%). Minor bleeding was reported in 1,143 patients (4.7%). Rates of major bleeding decreased from 11.5% in 2007-2010 to 5.5% in 2019-2022 (Ptrend < 0.001). Dual antiplatelet therapy was associated with higher major bleeding rates compared with single antiplatelet therapy (12.2% vs 9.1%; OR: 1.40; 95% CI: 1.13-1.72; P = 0.002). Patients with major bleeding had increased mortality risk during the first 30 days (14.1% vs 4.3%; OR: 3.66; 95% CI: 3.11-4.31; P < 0.001) and during 1-year follow-up (27.8% vs 14.5%; HR: 1.50; 95% CI: 1.41-1.59; P < 0.001). Minor bleeding did not affect 1-year mortality risk (16.7% vs 14.5%; HR: 1.11; 95% CI: 0.93-1.32; P = 0.27). Predictors of major bleeding were female sex and peripheral vascular disease. CONCLUSIONS: Bleeding complications remain frequent and important in patients undergoing transfemoral TAVR. Increased mortality risk in major bleeding persists after the initial 30 days.
