Abstract Background Patients with prior myocardial infarction (MI) are at increased risk for recurrent cardiovascular events. Advances in treatment in the last decade has improved prognosis of patients with acute coronary syndrome (ACS), yet it is not known whether similar trends exist in patients with prior MI who are admitted with an ACS, a particularly high-risk group. Methods Patients admitted with ACS who were enrolled in the ACS Israeli Surveys (ACSIS). Patients were stratified by early (2000–2008) and late (2010–2016) time-periods and by prior MI status. Clinical outcomes included 30-d MACE (death, MI, stroke, unstable angina, stent thrombosis, urgent revascularization) and 1-year mortality. Results A total of 15,211 ACS patients were included, of whom 4627 (30%) had a prior MI. These patients were older (67y vs. 63y), more commonly male, had more prior comorbidities, and a higher proportion had a GRACE score>140 (38.4% vs 12.2%). Patients with prior MI received more prior medications such as aspirin, statins, antihypertensives and hypoglycemics. During time, utilization of guideline-recommended therapies such as P2Y12 inhibitors, statins, and PCI had significantly improved in patients with prior MI. However, compared with patients without prior MI, they were still treated less commonly by PCI (61% vs. 74%). Overall, patients with prior MI had a higher 30-d MACE (13.7% vs 17.2%, p<0.001) and 1-year mortality (8.2% vs. 13.1%, p<0.001). In patients with prior MI, during time, 30d MACE nearly halved (22.7% to 11.8%) and 1-year mortality also decreased (15.5% to 10.7%). Upon adjustment, prior MI was independently associated with 1-year mortality (HR 1.13, 95% CI 1.01–1.26, p=0.04) and the late time-period was associated with reduced 1-year mortality (HR 0.75, 95% CI 0.65–0.84, p<0.001). Conclusion Patients with prior MI have a worse prognosis after ACS despite being treated with prior medications and improvement in guideline-based therapies. Although still undertreated, their clinical outcome has significantly improved throughout the years.

Patients who have previously had a myocardial infarction (MI) are considered a high-risk group with increased risk for cardiovascular (CV) events. During the last decade, the outcome of acute coronary syndrome (ACS) patients has improved due to advances in medical therapy and interventional techniques. We aimed to examine temporal trends and outcomes of patients with prior MI admitted due to ACS from the Acute Coronary Syndrome Israeli Survey (ACSIS). Included were 16,934 ACS patients, of whom 31.4% had prior MI. For temporal trend analysis, the cohort was divided into an early period (2000–2008) and late period (2010–2018). For patients with prior MI, patients in the late period had a higher rate of CV risk factors and were treated more frequently with revascularization and guidelines-directed medical therapy. Recurrent MI (6.7% vs. 12%, p < 0.001), MACE (10.6% vs. 21%, p < 0.001) and 1-year mortality (10.7% vs. 14.6%, p < 0.001) were significantly lower in the late period. However, the mortality rate for patients with prior MI remained higher compared with patients without prior MI (10.7% vs. 6.8% p < 0.001) with an overall higher mortality rate in the STEMI group. Thus, despite significant improvement in outcome measures in the contemporary era, ACS patients with prior MI are still at increased risk for recurrent ischemic CV events and mortality.

Vascular calcification contributes to the pathogenesis of coronary artery disease while matrix Gla protein (MGP) was recently identified as a potent inhibitor of vascular calcification. MGP fractions, such as dephosphorylated-uncarboxylated MGP (dp-ucMGP), lack post-translational modifications and are less efficient in vascular calcification inhibition. We sought to compare dp-ucMGP levels between patients with acute coronary syndrome (ACS), stratified by ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) status. Physical examination and clinical data, along with plasma dp-ucMGP levels, were obtained from 90 consecutive ACS patients. We observed that levels of dp-ucMGP were significantly higher in patients with NSTEMI compared to STEMI patients (1063.4 ± 518.6 vs. 742.7 ± 166.6 pmol/L, p < 0.001). NSTEMI status and positive family history of cardiovascular diseases were only independent predictors of the highest tertile of dp-ucMGP levels. Among those with NSTEMI, patients at a high risk of in-hospital mortality (adjudicated by GRACE score) had significantly higher levels of dp-ucMGP compared to non-high-risk patients (1417.8 ± 956.8 vs. 984.6 ± 335.0 pmol/L, p = 0.030). Altogether, our findings suggest that higher dp-ucMGP levels likely reflect higher calcification burden in ACS patients and might aid in the identification of NSTEMI patients at increased risk of in-hospital mortality. Furthermore, observed dp-ucMGP levels might reflect differences in atherosclerotic plaque pathobiology between patients with STEMI and NSTEMI.

Background. COVID-19 increases the risk of developing thromboembolic complications, including acute myocardial infarction, in the acute period of the disease. The long-term consequences of COVID-19 are poorly understood. At the same time, the available data on an increased risk of acute coronary syndrome after infectious diseases allow us to make an assumption about a similar risk in COVID-19. The aim of the study was to study the anamnestic and laboratory diagnostic data in patients with acute coronary syndrome after COVID-19. Methods. The study included 185 patients with acute coronary syndrome who were admitted to the State Clinical Hospital No. 13 in Moscow in the period from May to December 2020. 2 groups were identified: group 1 109 patients with ACS who had previously suffered COVID-19, group 2 76 patients with ACS without COVID-19 in the past. The patients were collected anamnesis, including: the fact of smoking and alcohol consumption, heredity, previous diseases, including diabetes mellitus, acute myocardial infarction, previously performed PCI. Information about the COVID-19 infection has been collected (the duration of the disease, the course of the disease). A clinical and laboratory examination was conducted, including the determination of body mass index (BMI), examination for antibodies to COVID-19, determination of the lipid profile level (total cholesterol, LDL, HDL, triglycerides), blood glucose level, C-RB. The analysis was performed on automatic biochemical analyzers Hitachi-902, 912 (Roche Diagnostics, Japan). All patients underwent coronary angiography. Results. In patients with ACS with previously transferred COVID-19, the development of the disease occurred at a younger age compared to patients without transferred COVID-19. Among the patients with COVID-19, body weight was significantly lower, there were fewer smokers, concomitant type 2 diabetes mellitus and transferred ONMC were less common. In laboratory parameters, lower triglyceride levels were observed in patients with ACS with COVID-19 compared with those of patients without COVID-19. In the laboratory parameters of blood clotting in patients with ACS with COVID-19, higher APTT, thrombin time, fibrinogen level, D-dimer were noted. The indicated laboratory parameters in the groups had statistically significant differences. In ACS patients with a previous COVID-19, compared with patients without COVID-19, the lesion of 2 or more coronary vessels was more common in the anamnesis. Conclusion. According to the results of our study, it was revealed that multivessel coronary artery damage in patients after COVID-19 in comparison with patients without COVID-19 develops significantly more often, while these patients are significantly less likely to have DM and previously suffered ONMC, the level of TG is significantly lower.

Acute myocardial infarction remains a leading cause of morbidity and mortality. While iron deficient heart failure patients are at increased risk of future cardiovascular events and see improvement with intravenous supplementation, the clinical relevance of iron deficiency in acute coronary syndrome remains unclear. We aimed to evaluate the prognostic value of iron deficiency in the acute coronary syndrome (ACS). Levels of ferritin, iron, and transferrin were measured at baseline in 836 patients with ACS. A total of 29.1% was categorized as iron deficient. The prevalence of iron deficiency was clearly higher in women (42.8%), and in patients with anemia (42.5%). During a median follow-up of 4.0 years, 111 subjects (13.3%) experienced non-fatal myocardial infarction (MI) and cardiovascular mortality as combined endpoint. Iron deficiency strongly predicted non-fatal MI and cardiovascular mortality with a hazard ratio (HR) of 1.52 (95% confidence interval (CI) 1.03-2.26; p = 0.037) adjusted for age, sex, hypertension, smoking status, diabetes, hyperlipidemia, body-mass-index (BMI) This association remained significant (HR 1.73 (95% CI 1.07–2.81; p = 0.026)) after an additional adjustment for surrogates of cardiac function and heart failure severity (N-terminal pro B-type natriuretic peptide, NT-proBNP), for the size of myocardial necrosis (troponin), and for anemia (hemoglobin). Survival analyses for cardiovascular mortality and MI provided further evidence for the prognostic relevance of iron deficiency (HR 1.50 (95% CI 1.02–2.20)). Our data showed that iron deficiency is strongly associated with adverse outcome in acute coronary syndrome.

Abstract Aims The value of platelet function testing (PFT) in predicting clinical outcomes and guiding P2Y12-inhibitor treatment is uncertain. In a pre-specified sub-study of the TROPICAL-ACS trial, we assessed ischaemic and bleeding risks according to high platelet reactivity (HPR) and low platelet reactivity (LPR) to ADP in patients receiving uniform prasugrel vs. PFT-guided clopidogrel or prasugrel. Methods and results Acute coronary syndrome patients with PFT done 14 days after hospital discharge were included with prior randomization to uniform prasugrel for 12 months (control group, no treatment modification) vs. early de-escalation from prasugrel to clopidogrel and PFT-guided maintenance treatment (HPR: switch-back to prasugrel, non-HPR: clopidogrel). The composite ischaemic endpoint included cardiovascular death, myocardial infarction, or stroke, while key safety outcome was Bleeding Academic Research Consortium (BARC) 2–5 bleeding, from PFT until 12 months. We identified 2527 patients with PFT results available: 1266 were randomized to the guided and 1261 to the control group. Before treatment adjustment, HPR was more prevalent in the guided group (40% vs. 15%), while LPR was more common in control patients (27% vs. 11%). Compared to control patients without HPR on prasugrel (n = 1073), similar outcomes were observed in guided patients kept on clopidogrel [n = 755, hazard ratio (HR): 1.06 (0.57–1.95), P = 0.86] and also in patients with HPR on clopidogrel switched to prasugrel [n = 511, HR: 0.96 (0.47–1.96), P = 0.91]. In contrast, HPR on prasugrel was associated with a higher risk for ischaemic events in control patients [n = 188, HR: 2.16 (1.01–4.65), P = 0.049]. Low platelet reactivity was an independent predictor of bleeding [HR: 1.74 (1.18–2.56), P = 0.005], without interaction (Pint = 0.76) between study groups. Conclusion Based on this substudy of a randomized trial, selecting prasugrel or clopidogrel based on PFT resulted in similar ischaemic outcomes as uniform prasugrel therapy without HPR. Although infrequent, HPR on prasugrel was associated with increased risk of ischaemic events. Low platelet reactivity was a strong and independent predictor of bleeding both on prasugrel and clopidogrel.

Abstract Background Type 2 myocardial infarction is common and associated with substantial risk of adverse clinical outcomes, worse than type 1 myocardial infarction, with as few as 30% of patients still alive at five years. However, this broad diagnostic term encompasses multiple mechanisms of supply-demand imbalance, which may be associated with different risks of adverse outcomes. Purpose We aimed to assess the prevalence and clinical outcomes of different mechanisms of supply-demand imbalance related to survival in the High-STEACS (High-Sensitivity Troponin in the Evaluation of patients with Acute Coronary Syndrome) randomised controlled trial. Methods The High-STEACS trial was a stepped wedge cluster randomised controlled trial in ten hospitals across Scotland, including 48,282 consecutive patients with suspected acute coronary syndrome. The diagnosis was adjudicated according to the Fourth Universal Definition of Myocardial Infarction. In patients with type 2 myocardial infarction, we prospectively adjudicated the cause for supply demand imbalance. Linkage of electronic healthcare records was used to track investigation, treatments and clinical outcomes. We used the Kaplan-Meier method, the log rank test and cox regression models adjusted for age, sex, renal function and co-morbidities to evaluate the risk of future all-cause mortality between categories. Results We identified 1,121 patients with type 2 myocardial infarction (age 74- ± 14, 55% female). At one year, death from any cause occurred in 23% (258/1,121) of patients. The most common reason for supply-demand imbalance was tachyarrhythmia in 55% (616/1,121), followed by hypoxaemia in 20% (219/1,121) of patients. Tachyarrhythmia was associated with reduced future risk of all-cause mortality (adjusted HR 0.69, 95% CI 0.43–1.09), similar to those with type 1 myocardial infarction. Comparatively, patients with hypoxaemia appeared at highest risk (adjusted HR 1.75, 95% CI 1.09–2.80). Conclusion The mechanism of myocardial oxygen supply-demand imbalance is associated with future prognosis, and should be considered when risk stratifying patients with type 2 myocardial infarction.

ObjectivesAnxiety has been suggested to be associated with poor outcomes in patients with acute coronary syndrome (ACS). However, results of previous follow-up studies were inconsistent. The aim of this meta-analysis was to evaluate the association between anxiety and clinical outcomes in patients with ACS, and to investigate the potential role of depression underlying the above association.DesignA meta-analysis of prospective follow-up studies.SettingHospitals.ParticipantsPatients with ACS.InterventionsWe included related prospective follow-up studies up through 20 July 2019 that were identified by searching PubMed and Embase databases. A random-effect model was used for the meta-analysis. Anxiety was evaluated by validated instruments at baseline.Primary and secondary outcome measuresWe determined the association between anxiety and risks of mortality and adverse cardiovascular events (MACEs) in patients with ACS.ResultsOur analysis included 17 studies involving 39 038 patients wqith ACS. Anxiety was independently associated with increased mortality risk (adjusted risk ratio (RR) 1.21, 95% CI 1.07 to 1.37, p=0.002) and MACEs (adjusted RR 1.47, 95% CI 1.24 to 1.74, p<0.001) in patients with ACS. Subgroup analyses showed that depression may at least partly confound the association between anxiety and poor outcomes in patients with ACS. Adjustment of depression significantly attenuated the association between anxiety and MACEs (adjusted RR 1.25, 95% CI 1.04 to 1.52, p=0.02). Moreover, anxiety was not significantly associated with mortality risk after adjusting for depression (adjusted RR 0.88, 95% CI 0.66 to 1.17, p=0.37).ConclusionsAnxiety is associated with increased risk of mortality and MACEs in patients with ACS. However, at least part of the association may be confounded by concurrent depressive symptoms in these patients.

Introduction The benefits of short versus long-term dual antiplatelet therapy (DAPT) based on the third generation P2Y12 antagonists prasugrel or ticagrelor, in patients with acute coronary syndromes treated with percutaneous coronary intervention remain to be clearly defined due to current evidences limited to patients treated with clopidogrel. Methods All acute coronary syndrome patients from the REgistry of New Antiplatelets in patients with Myocardial Infarction (RENAMI) undergoing percutaneous coronary intervention and treated with aspirin, prasugrel or ticagrelor were stratified according to DAPT duration, that is, shorter than 12 months (D1 group), 12 months (D2 group) and longer than 12 months (D3 group). The three groups were compared before and after propensity score matching. Net adverse clinical events (NACEs), defined as a combination of major adverse cardiac events (MACEs) and major bleedings (including therefore all cause death, myocardial infarction and Bleeding Academic Research Consortium (BARC) 3–5 bleeding), were the primary end points, MACEs (a composite of all cause death and myocardial infarction) the secondary one. Single components of NACEs were co-secondary end points, along with BARC 2–5 bleeding, cardiovascular death and stent thrombosis. Results A total of 4424 patients from the RENAMI registry with available data on DAPT duration were included in the model. After propensity score matching, 628 patients from each group were selected. After 20 months of follow up, DAPT for 12 months and DAPT for longer than 12 months significantly reduced the risk of NACE (D1 11.6% vs. D2 6.7% vs. D3 7.2%, p = 0.003) and MACE (10% vs. 6.2% vs. 2.4%, p < 0.001) compared with DAPT for less than 12 months. These differences were driven by a reduced risk of all cause death (7.8% vs. 1.3% vs. 1.6%, p < 0.001), cardiovascular death (5.1% vs. 1.0% vs. 1.2%, p < 0.0001) and recurrent myocardial infarction (8.3% vs. 5.2% vs. 3.5%, p = 0.002). NACEs were lower with longer DAPT despite a higher risk of BARC 2–5 bleedings (4.6% vs. 5.7% vs. 6.2%, p = 0.04) and a trend towards a higher risk of BARC 3–5 bleedings (2.4% vs. 3.3% vs. 3.9%, p = 0.06). These results were not consistent for female patients and those older than 75 years old, due to an increased risk of bleedings which exceeded the reduction in myocardial infarction. Conclusion In unselected real world acute coronary syndrome patients treated with percutaneous coronary intervention, DAPT with prasugrel or ticagrelor prolonged beyond 12 months markedly reduces fatal and non-fatal ischaemic events, offsetting the increased risk deriving from the higher bleeding risk. On the contrary, patients >75 years old and female ones showed a less favourable risk–benefit ratio for longer DAPT due to excess of bleedings.
