Spiked helmet sign is a novel electrocardiogram marker that reflects a poor prognosis, and may mimic myocardial infarction, especially in patients with an acute alteration of mental status or out-of-hospital cardiac arrest. In cases where a spiked helmet sign is missed, there may be a delay in surgical intervention for the underlying conditions because of unnecessary cardiac catheterization. In addition, antiplatelet agents for acute coronary syndrome in such cases can lead to catastrophic complications. Therefore, early recognition of spiked helmet sign is useful for timely correction of the underlying disease and prevention of poor outcomes. Herein, we describe a rare case of a patient with internal bleeding and subarachnoid hemorrhage presenting with spiked helmet sign on an electrocardiogram.

The identification of new biomarkers allowing an early and more accurate characterization of patients with ST-segment elevation myocardial infarction (STEMI) is still needed, and exosomes represent an attractive diagnostic tool in this context. However, the characterization of their protein cargo in relation to cardiovascular clinical manifestation is still lacking. To this end, 35 STEMI patients (17 experiencing resuscitated out-of-hospital cardiac arrest (OHCA-STEMI) and 18 uncomplicated) and 32 patients with chronic coronary syndrome (CCS) were enrolled. Plasma exosomes were characterized by the nanoparticle tracking analysis and Western blotting. Exosomes from STEMI patients displayed a higher concentration and size and a greater expression of platelet (GPIIb) and vascular endothelial (VE-cadherin) markers, but a similar amount of cardiac troponin compared to CCS. In addition, a difference in exosome expression of acute-phase proteins (ceruloplasmin, transthyretin and fibronectin) between STEMI and CCS patients was found. GPIIb and brain-associated marker PLP1 accurately discriminated between OHCA and uncomplicated STEMI. In conclusion, the exosome profile of STEMI patients has peculiar features that differentiate it from that of CCS patients, reflecting the pathophysiological mechanisms involved in STEMI. Additionally, the exosome expression of brain- and platelet-specific markers might allow the identification of patients experiencing ischemic brain injury in STEMI.

The aimof the study was to create a patient portrait, to evaluate prognosis, and establish the principles of therapy in patients with acute coronary syndrome without ST elevation with non-obstructive coronary atherosclerosis in comparison with the obstructive coronary atherosclerosis group.Material and Methods. Data come from the acute coronary syndrome register REСORD-3 that was implemented in the Emergency Cardiology Department of Cardiology Research Institute, Tomsk National Research Medical Centre, along with 45 other centers in Russia. Patients with myocardial infarction without ST segment elevation who were exposed to coronary angiography were separated into two independent groups based on whether they had MINОСА or not: 148 persons with non-obstructive coronary atherosclerosis and 537 persons with obstructive coronary atherosclerosis.Results. Non-obstructive coronary atherosclerosis group, compared to obstructive coronary atherosclerosis, comprised 75 women (50.7%) compared to 177 men (32.9%). Hypertension was detected less often in this group: 120 (81.1%) versus 475 (88.5%). The rates of diabetes mellitus were 16 (10.8%) versus 115 (21.4%) and the rates of smoking were 162 patients (30.2%) versus 32 (21.6%), respectively, in patients with and without non-obstructive coronary atherosclerosis. Non-obstructive coronary atherosclerosis group had significantly lower rate of individuals with diagnostic increase in cardiospecific enzymes. This may be indicative of non-prolonged myocardial ischemia that, in some cases, does not lead to necrosis. The final diagnosis of non-ST segment elevation myocardial infarction was significantly less confirmed in patients with non-obstructive coronary atherosclerosis (14.8 vs. 45.3%). However, in this group, the “other cardiac cause of hospitalization” was more frequent (29.7 vs. 2.2% of cases), which explains the need to continue the diagnostic search to exclude all possible causes of the chest pain. The variety of final diagnoses in patients with acute coronary syndrome with non-obstructive coronary atherosclerosis and “clean” coronary arteries should encourage a thorough analysis of the pathogenesis in each of these patients.Conclusion. A typical acute coronary syndrome patient with non-obstructive coronary atherosclerosis without ST segment elevation was represented by a 59 (53:65)-year-old woman with traditional risk factors for coronary heart disease, but the incidence of each of these factors was less than in the obstructive coronary atherosclerosis group. Final diagnosis of non-ST segment elevation myocardial infarction was confirmed significantly less often in patients with non-obstructive coronary atherosclerosis. The mortality rates did not differ between groups and were minimal. Acute coronary syndrome patients with non-obstructive coronary atherosclerosis without ST segment elevation were less likely to receive ticagrelor and statins in hospital, but they were administered more often with fondaparinux. Patients with non-obstructive coronary atherosclerosis at discharge were less likely to be recommended to take antiplatelet agents, statins, and nitrates.

AbstractMajor adverse cardio-cerebrovascular events (MACCE) in ST-segment elevation myocardial infarction (STEMI) are still high, although there have been advances in pharmacology and interventional procedures. Proprotein convertase subtilisin/Kexin type 9 (PCSK9) is a serine protease regulating lipid metabolism associated with inflammation in acute coronary syndrome. The MACCE is possibly related to polymorphisms in PCSK9. A prospective cohort observational study was designed to confirm the association between polymorphism of E670G and R46L in the PCSK9 gene with MACCE in STEMI. The Cox proportional hazards model and Spearman correlation were utilized in the study. The Genotyping of PCSK9 and ELISA was assayed.Sixty-five of 423 STEMI patients experienced MACCE in 6 months. The E670G polymorphism in PCSK9 was associated with MACCE (hazard ratio = 45.40; 95% confidence interval: 5.30–390.30; p = 0.00). There was a significant difference of PCSK9 plasma levels in patients with previous statin consumption (310 [220–1,220] pg/mL) versus those free of any statins (280 [190–1,520] pg/mL) (p = 0.001).E670G polymorphism of PCSK9 was associated with MACCE in STEMI within a 6-month follow-up. The plasma PCSK9 level was higher in statin users.

Aims To investigate the different risk factors among different subtypes of patients with acute coronary syndrome (ACS). Methods A total of 296 patients who had ACS were retrospectively enrolled. Blood and echocardiographic indices were assessed within 24 hours after admission. Differences in risk factors and Gensini scores of coronary lesions among three groups were analyzed. Results Univariate analysis of risk factors for ACS subtypes showed that age, and levels of fasting plasma glucose, amino-terminal pro-brain natriuretic peptide, and creatine kinase isoenzyme were significantly higher in patients with non-ST-segment elevation myocardial infarction (NSTEMI) than in those with unstable angina pectoris (UAP). Logistic multivariate regression analysis showed that amino-terminal pro-brain natriuretic peptide and the left ventricular ejection fraction (LVEF) were related to ACS subtypes. The left ventricular end-diastolic diameter was an independent risk factor for UAP and ST-segment elevation myocardial infarction (STEMI) subtypes. The severity of coronary stenosis was significantly higher in NSTEMI and STEMI than in UAP. Gensini scores in the STEMI group were positively correlated with D-dimer levels (r = 0.429) and negatively correlated with the LVEF (r = −0.602). Conclusion Different subtypes of ACS have different risk factors. Our findings may have important guiding significance for ACS subtype risk assessment and clinical treatment.

Abstract Background Myocardial infarction (MI) in nonagenarians is associated with high morbidity and mortality. Nonetheless, this population has typically been underrepresented in cardiovascular clinical trials. Objective The aim of this study was to evaluate outcomes of nonagenarian patients presenting with MI who underwent either conservative or invasive management. Methods We retrospectively included all consecutive patients equal to or older than 90yo admitted with non-ST segment elevation (NSTEMI) or ST segment elevation MI (STEMI) in four tertiary care centers between 2005 and 2018. Patients with type 2 myocardial infarction were excluded. We collected patients' baseline characteristic and procedural data. In-hospital and at 1-year follow-up all-cause mortality and major adverse cardiovascular events were assessed. Results 523 patients (mean age 92.6±2 years; 60% females) were analyzed. Overall, 184 patients (35.2%) underwent percutaneous coronary intervention (PCI), increasing over the years, mostly in STEMI group (from 16% of patients in 2005 to 75% in 2018). PCI was preferred in those subjects with less prevalence of disability for activities of daily living (p<0.01). The use of a radial access (76.6%) and bare metal stents (52.7%) was predominant. No significant differences were found in the incidence of major bleeding events or MI-related mechanical complications between both strategies. During index hospitalization, 99 (18.9%) patients died. Whereas no differences were found in the NSTEMI group (p=0.61), a significant lower in-hospital mortality was observed in STEMI group treated with PCI (p<0.01). At one-year follow up, 203 (38.8%) patients died, most of them due to a cardiovascular cause (60.6%). PCI was related to a lower all-cause mortality in either NSTEMI (p<0.01) or STEMI groups (p<0.01) however, lower cardiovascular mortality was only found in STEMI group (p=0.03). Conclusion An invasive approach was performed in over a third of nonagenarian patients, carrying prognostic implications and with a few numbers of complications. PCI seems to be the preferred strategy for STEMI in this high-risk population in spite of age. Figure 1 Funding Acknowledgement Type of funding source: None

Abstract Objectives To assess the evolution of hospital discharge management, 6 months hospitalization and mortality over the years of all patients admitted with ST segment elevation myocardial infarction (STEMI) in Portugal. Methods A nationwide electronic prospective registry that included all patients admitted to Portuguese hospitals with a diagnosis of Acute Coronary Syndrome since 2002 until 2018 was used to collect all data relative to patients admitted with a STEMI diagnosis during that time frame. Data on demographic data, clinical status, revascularization strategy, discharge medication and 6 months hospitalization and mortality were obtained. We compared the data and its evolution over the years to assess for trends. For statistical analysis, Qui-square tests were used to assess trends in categorical variables, and Kruskal-Wallis tests were used to assess trends in numerical variables. A p-value <0.05 was considered statistically significant. Results During the study, a total of 23807 patients were admitted for STEMI in Portuguese hospitals, 74.3% were male and average age of 63.9±13.6 years. We report a progressive and significant increase the use of primary angioplasty versus fibrinolysis (24.3% to 98.4%, p<0.001), in coronary angioplasties (36.4% to 73.2%, p<0.001), in the use of drug-eluting stents (0% to 70.1%, p<0.001), and a decrease in the patients that underwent surgery (6.8% to 1.3%, p<0.001) and intra-aortic balloon pump (1.8% to 0%, p=0.009), resulting in a decrease in in-hospital mortality from 9.9% to 6.1% (p<0.001). At discharge, we report a progressive increase in the prescription of P2Y12 inhibitors (21.1% to 95.2%, p<0.001), beta-blockers (68.8% to 83.8%, p<0.001), RAAS inhibitors (69.5% to 86.7%, p<0.001) and statins (79.6% to 94.9%, p<0.001), while the prescription of aspirin (94.1% para 94.8%, p=0.428), calcium channel blockers (5.3% to 5.6%, p<0.684) stayed stable, and there was a decrease in the prescription of nitrates (52.9% to 5.8%, p<0.001). Hospital admissions at 6 months consistently and progressively reduced over time (18.6% to 8.5%, p<0.001) as well as mortality (6.7% para 4.3%, p<0.001). Conclusion Post discharge treatment of STEMI patients in Portuguese hospitals has evolved according to guidelines, with higher prescription of medication proven to reduce outcomes, resulting in lower hospitalization rates and mortality. 6 Month Outcomes over the years Funding Acknowledgement Type of funding source: Public Institution(s).

In pre-hospital care, an accurate and quick diagnosis of ST-segment elevation myocardial infarction (STEMI) is imperative to promptly kick-off the STEMI network with a direct transfer to the cardiac catheterization laboratory (cath lab) in order to reduce myocardial infarction size and mortality. Aa atherosclerotic plaque rupture is the main mechanism responsible for STEMI. However, in a small percentage of patients, emergency coronarography does not reveal any significant coronary stenosis. The fluoropyrimidine agents such as 5-Fluorouracil (5-FU) and capecitabine, widely used to treat gastrointestinal, breast, head and neck cancers, either as a single agent or in combination with other chemotherapies, can cause potentially lethal cardiac side effects. Here, we present the case of a patient with 5-FU cardiotoxicity resulting in an acute coronary syndrome (ACS) with recurrent episodes of chest pain and ST-segment elevation.. Our case report highlights the importance of widening the knowledge among cardiologists of the side effects of chemotherapeutic drugs, especially considering the rising number of cancer patients around the world and that fluoropyrimidines are the main treatment for many types of cancer, both in adjuvant and advanced settings.

Patients with coronary artery disease (CAD) present clinically when their disease enters an unstable phase known as an acute coronary syndrome (ACS), in which the cap of a previously stable atheromatous coronary plaque ruptures or erodes, which in turn activates a thrombotic cascade that may lead to coronary artery occlusion, myocardial infarction (MI), cardiogenic shock, and patient death. There are nearly 2 million episodes of ACS in the United States annually; it is the most common reason for hospitalization with CAD and is the leading cause of death in the developed world. ACS patients include those with unstable angina (UA), non–ST segment elevation myocardial infarction (non-STEMI), and ST segment elevation myocardial infarction (STEMI) and patients who die suddenly of an arrhythmia precipitated by coronary occlusion. The distinction among various ACS subgroups reflects varying characteristics of clinical presentation (presence or absence of elevated cardiac biomarkers) and the type of electrocardiographic (ECG) changes manifested on the initial ECG at the time of hospitalization. This chapter focuses on UA and non-STEMI. A graph outlines mortality risks faced by patients with varying degrees of renal insufficiency. An algorithm describes the suggested management of patients admitted with UA or non-STEMI. Tables describe the risk stratification of the patient with chest pain, categories of Killip class, examination findings of a patient with high-risk ACS, diagnosis of MI, causes of troponin elevation other than ischemic heart disease, initial risk stratification of ACS patients, and long-term medical therapies and goals in ACS patients. This review contains 2 highly rendered figures, 11 tables, and 76 references.

Electrocardiographic Findings

Acute myocardial infarction is the leading cause of death in the world and the electrocardiogram remains the diagnostic tool for determining an acute myocardial infarction with ST-segment elevation. In spite of this, only half of the patients present classic electrocardiogram findings compatible with the ST-elevation infarction criteria. There is a spectrum of electrocardiographic findings that may reflect a phenomenon of acute coronary occlusion, which should be promptly recognized by the clinician to offer early reperfusion therapy.
