Background and objectives: early reports showed a decrease in admission rates and an increase in mortality of patients with acute myocardial infarction (AMI) during the first wave of COVID-19 pandemic. We sought to investigate whether the COVID-19 pandemic and associated lockdown had an impact on the ischemia time and prognosis of patients suffering from AMI in the settings of low COVID-19 burden. Materials and Methods: we conducted a retrospective data analysis from a tertiary center in Lithuania of 818 patients with AMI. Data were collected from 1 March to 30 June in 2020 during the peri-lockdown period (2020 group; n = 278) and compared to the same period last year (2019 group; n = 326). The primary study endpoint was all-cause mortality during 3 months of follow-up. Secondary endpoints were heart failure severity (Killip class) on admission and ischemia time in patients with acute ST segment elevation myocardial infarction (STEMI). Results: there was a reduction of 14.7% in admission rate for acute myocardial infarction (AMI) during the peri-lockdown period. The 3-month mortality rate did not differ significantly (6.9% in 2020 vs. 10.5% in 2019, p = 0.341 for STEMI patients; 5.3% in 2020 vs. 2.6% in 2019, p = 0.374 for patients with acute myocardial infarction without ST segment elevation (NSTEMI)). More STEMI patients presented with Killip IV class in 2019 (13.5% vs. 5.5%, p = 0.043, respectively). There was an increase of door-to-PCI time (54.0 [42.0–86.0] in 2019; 63.5 [48.3–97.5] in 2020, p = 0.018) and first medical contact (FMC)-to-PCI time (101.0 [82.5–120.8] in 2019; 115 [97.0–154.5] in 2020, p = 0.01) during the pandemic period. Conclusions: There was a 14.7% reduction of admissions for AMI during the first wave of COVID-19. FMC-to-PCI time increased during the peri-lockdown period, however, it did not translate into worse survival during follow-up.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction  Nonagenarians have a high rate of comorbidities and are underrepresented in studies of ischemic heart disease. It is unknown whether treatment at discharge is useful in preventing adverse events at follow up.  Purpose  The aim of this study is to evaluate the secondary prevention with medical treatment in nonagenarians with acute myocardial infarction. Methods A multicenter, observational and retrospective study was carried out in nonagenarians admitted by acute coronary syndrome (ACS) between January 2005 and December 2018. Baseline characteristics, interventional procedures, treatment at discharge and outcomes at 1 year were evaluated. Patients with type 2 acute myocardial infarction were excluded.  Results  680 patients (92,6 ± 2,4 years old) were included. Hypertension was present in 79.4% of the entire population. Percutaneous coronary intervention (PCI) was performed in 32.1% of patients, and this group had a higher GRACE score compared to the conservative treatment group (177 versus 172; p = 0.001). Patients with ST-segment elevation myocardial infarction (STEMI) were more likely to receive an invasive strategy than the non-ST segment elevation myocardial infarction (NSTEMI) (61.5% versus 41.5%; p= 0.001). 263 patients died at 1 year follow up with in-hospital mortality of 17%. In STEMI group, patients with statins and dual antiplatelet therapy at discharge had lower mortality during follow up compared to those who did not received (26.7 % versus 41.5%; p = 0.001 and 31% versus 22%; p = 0.02, respectively) (Image 1).  Conclusions Nonagenarian patients with ACS have a high prevalence of hypertension and ICP procedures are not performed frequently. They also have a high mortality rate, although statins and dual antiplatelet therapy could be an effective secondary prevention. Abstract Figure.

This recent Turkish Myocardial Infarction registry reported that guidelines are largely implemented in patients with acute myocardial infarction (MI) in Turkey. We aimed to obtain up-to-date information for short- and midterm outcomes of acute MI. Fifty centers were selected using probability sampling, and all consecutive patients with acute MI admitted to these centers (between November 1 and 16, 2018) were enrolled. Among 1930 (mean age 62 ± 13 years, 26% female) patients, 1195 (62%) had non-ST segment elevation myocardial infarction (NSTEMI) and 735 (38%) had ST segment elevation myocardial infarction (STEMI). Percutaneous coronary intervention (PCI) was performed in 94.4% of patients with STEMI and 60.2% of those with NSTEMI. Periprocedural mortality occurred in 4 (0.3%) patients. In-hospital mortality was significantly higher in STEMI than in patients with NSTEMI (5.4% vs 2.9%, respectively; P = .006). However, the risk became slightly higher in the NSTEMI group at 1 year. Women with STEMI had a significantly higher in-hospital mortality compared with men (11.2% vs 3.8%; P < .001); this persisted at follow-up. In conclusion, PCI is performed in Turkey with a low risk of complications in patients with acute MI. Compared with a previous registry, in-hospital mortality decreased by 50% within 20 years; however, the risk remains too high for women with STEMI.

Aim      To study features of diagnosis and treatment of acute myocardial infarction (AMI) in Russian hospitals, results of the treatment, and early and late outcomes (6 and 12 months after AMI diagnosis); to evaluate the consistence of the treatment with clinical guidelines; and to evaluate patients’ compliance with the treatment.Material and methods  The program was designed for 3 years, including 24 months for recruitment of patients to the study. The study will include 10, 000 patients hospitalized with a confirmed diagnosis (I21 according to ICD-10) of ST segment elevation acute myocardial infarction (MI) (STEMI) or non-ST segment elevation MI (NSTEMI) based on criteria of the European Society of Cardiology Guidelines on Forth Universal Definition of Myocardial Infarction (2018). The follow-up period was divided into three stages: observation during the stay in the hospital and at 6 and 12 months following inclusion into the registry. The primary endpoint included cardiac death, nonfatal MI during the hospitalization and after one-year follow-up. Secondary endpoints were 6-months and one-year incidence of repeated MI, heart failure, ischemic stroke, clinically significant hemorrhage, unscheduled revascularization after discharge from the hospital, and the proportion of patients who continue on statins, antiplatelet drugs, and drugs of other groups for 6 months and 1 year.Results The inclusion of patients into the registry started in 2020 and will continue for 24 months. By the time of the article publication (June, 2021), more than 2,000 patients will be included.Conclusion      REGION-MI (Russian rEGIstry Of acute myocardial iNfarction) is a multicenter, retrospective and prospective observational cohort study that excludes any interference with the clinical practice. Results of the registry will help to analyze a real picture of medical care provided to patients with myocardial infarction and to schedule ways to improve the situation.

Abstract Background ST-segment elevation myocardial infarction (STEMI) is associated with an intense acute inflammatory response and an increased risk of recurrent ischemic events. Prior studies of IL-1 blockade have shown conflicting results regarding the risk of future events. Methods We enrolled patients with STEMI within 12 hours of presentation at 3 sites in the United States of America. After revascularization, patients were randomly assigned to receive anakinra 100 mg twice daily, anakinra 100 mg once daily (standard dose) alternated with placebo once daily every 12 hours, or placebo every 12 hours for 14 days in 1:1:1 ratio. Prespecified exploratory endpoints for recurrent ischemic events, adjudicated by an independent committee, evaluated the composite risk of subsequent acute myocardial infarction (AMI, World Health Organization classification Type 1), unstable angina, or urgent revascularization. Data are expressed as median and interquartile range or number and percentage. Cox regression analysis was used to generate unadjusted hazard ratios and confidence intervals. (ClinicalTrials.gov number, NCT01950299) Results Of 311 patients screened, 99 subjects (81% males, 58% Caucasians, 55 [49–62] years of age) were randomly assigned to anakinra twice daily (N=31), anakinra once daily (N=33) or placebo (N=35). The cohort included patients with hypertension (57%), tobacco use (55%), diabetes mellitus (30%), and prior diagnosis of coronary artery disease (21%) without statistically significant imbalances in the demographic characteristics between groups (all P>0.05). Discharge medications for the index STEMI admission, in addition to the study medication, included aspirin (100%), statins (100%), P2Y12 inhibitors (100%), beta-blockers (90%), and angiotensin converting enzyme inhibitor/angiotensin receptor blocker (84%), without statistically significant imbalances between the 3 groups. Over the 1-year follow-up, recurrent ischemic events occurred in 5/35 (14.3%) patients treated with placebo and 6/64 (9.1%) patients treated with anakinra (hazard ratio = 0.68 [0.20–2.24], P=0.53). No differences were observed between high- and low-dose anakinra treatment groups. Conclusions A two week treatment with IL-1 receptor antagonist, anakinra, did not significantly decrease or increase recurrent ischemic events over the course of a 1-year follow-up in patients with STEMI.

INTRODUCTION Modern pharmacological reperfusion in ST segment elevation acute myocardial infarction means the application of fibrin specific thrombolytics combined with modern antiplatelets therapy dual antiplateles therapy, acetylsalicylic acid and clopidogrel, and enoxaparin. The contribution of each agent has been widely examined in large clinical studies, but not sufficiently has been known about the effects of a combined approach, where the early angiography and percutaneous coronary intervention is added during hospitalization, if necessary. OBJECTIVE The aim of the paper is to compare the effects of streptokinase and alteplase, together with the standard modern adjuvant antiplatelets and anticoagulation therapy (aspirin, clopidogrel, enoxaparin) in patients with ST segment elevation acute myocardial infarction, on electrocardiographic and angiographic signs of the achieved myocardial reperfusion. METHOD The prospective study included 127 patients with the first ST segment elevation acute myocardial infarction who were treated with a fibrinolytic agent in the first 6 hours from the chest pain onset. The examined group included 40 patients on the alteplase reperfusion therapy, while the control 87 patients were on the streptokinase therapy. All the patients received the same adjuvant therapy and all were examined by coronary angiography on the 3rd to 10th day of hospitalization. Reperfusion effects were estimated on the basis of the following: ST segment resolution at 60, 90 and 120 minutes, the appearance of reperfusion arrhythmias at the electrocardiogram, percentage of residual stenosis at the 'culprit' artery, TIMI coronary flow at the 'culprit' artery and the appearance of new major adverse coronary events in the 6-month-follow-up period. RESULTS By analysing the resolution of the sum of ST segment elevation in infarction leading 60 minutes after the beginning of the medication application, we received a statistically significantly higher resolution of ST segment in the group of patients who received alteplase (p<0.05). 60 minutes after the application of thrombolytics, 64% of patients at streptokinase showed the absence of ST segment resolution (<30%), and 32% of patients at alteplase (p<0.0001). Reperfusion arrhythmias as the sign of successful myocardial reperfusion were present in 62.5% of patients at alteplase and in 57.4% of patients at streptokinase, but the difference is not statistically significant. There was no statistically significant difference in the degree of residual stenosis at the 'culprit' artery in the compared groups of patients. TIMI 3 flow was achieved in 75% of patients at alteplase and in 38% of patients at streptokinase (p<0.0001). There was no statistically significant difference in the frequency of major adverse coronary events in the 6-month-follow-up period after acute myocardial infarction. CONCLUSION Alteplase with modern adjuvant therapy of ST segment elevation acute myocardial infarction shows the earlier achievement of coronary perfusion as well as better coronary flow compared to streptokinase. There is no statistically significant difference in the frequency of reperfusion arrhythmias, degree of residual stenosis at the 'culprit' artery and the frequency of new coronary events in the 6-month-follow-up period after acute myocardial infarction.
