acute coronary syndrome with ST segment elevation

Gerard Pasterkamp, Hester M den Ruijter, Peter Libby
The concept of the 'vulnerable plaque' originated from pathological observations in patients who died from acute coronary syndrome. This recognition spawned a generation of research that led to greater understanding of how complicated atherosclerotic plaques form and precipitate thrombotic events. In current practice, an increasing number of patients who survive their first event present with non-ST-segment elevation myocardial infarction (NSTEMI) rather than myocardial infarction (MI) with ST-segment elevation (STEMI)...

Electrocardiogram changes in subarachnoid hemorrhage (SAH) have been described as ST-T changes that mimic acute coronary syndrome and even acute ST-segment elevation myocardial infarction. Elevation of cardiac enzymes and abnormality of regional myocardial wall motion have been reported frequently for SAH. We report a case of an out-of-hospital cardiac arrest survivor with high suspicion of ST-segment elevation myocardial infarction based on the electrocardiogram and bedside echocardiography, who had normal coronary arteries on emergent coronary angiography...

Cocaine misuse is a known cause of acute coronary syndrome (ACS). Management of these patients has always been a challenge due to medication compliance and eventual risk of stent thrombosis. However, even cocaine misusers who are compliant with dual antiplatelet therapy have been reported to have stent thrombosis. All cases of cocaine-induced stent thrombosis reported in the literature have occurred within first year of stent placement (acute, subacute or late). We report a first case of very late stent thrombosis in a 54-year-old active cocaine misuser who presented with ST segment elevation myocardial infarction, which was successfully managed with percutaneous transluminal coronary angioplasty...

Spontaneous coronary artery dissection (SCAD) accounts approximately for 0.2% of cases of acute coronary syndrome. It is defined "spontaneous" in absence of any coronary wall damage. This disease affects primarily young women in good health, with no risk factors for coronary artery disease, especially during the postpartum period. Since the clinical presentation varies widely from no symptoms to typical angina and sudden cardiac death, SCAD incidence is underestimated.A 40-year-old woman, in the 8th week after delivery, was admitted to our emergency department because of acute chest pain, and a diagnosis of inferior and posterior non-ST-elevation myocardial infarction was made...

Thrombotic events such as myocardial infarction or stent thrombosis are the major cause of adverse outcomes in patients undergoing percutaneous coronary intervention (PCI). While current antiplatelet agents, anticoagulants, and PCI techniques have reduced the risk of thrombotic events in PCI-treated patients, a considerable hazard still remains. Cangrelor is an intravenous P2Y12 receptor antagonist that provides a rapid onset and maximal platelet inhibition, which is quickly reversible. In the large-scale CHAMPION PHOENIX trial, cangrelor was shown to reduce ischemic events significantly, including myocardial infarction and stent thrombosis, without increasing the risk of severe bleeding across the full spectrum of patients undergoing PCI, with substantial benefits in all patient subgroups examined...

BACKGROUND: Before our study, there were no data concerning complex evaluation of: plasma PCSK9 concentrations, transcript LDL receptor (LDLR), as well as the total amount of monocytes' LDLR in acute coronary syndrome (ACS) patients. PCSK9 levels in a few cohort studies were found to correlate with the number of white blood cells or platelets. The study aims to evaluate PCSK9-LDLR concentrations, as well as to find any association between PCSK9 and white blood cells (WBC) or platelets (PLT)...

BACKGROUND: Few studies have examined how antiplatelet therapies are selected during the routine care of acute myocardial infarction patients, particularly relative to the patient's estimated mortality and bleeding risks. METHODS AND RESULTS: We examined patients presenting with acute myocardial infarction treated with percutaneous coronary intervention at 233 US hospitals in the TRANSLATE-ACS observational study from April 2010 to October 2012. We developed a multivariable logistic regression model to identify factors associated with prasugrel selection...

BACKGROUND: Existing criteria recommended by ACC/ESC for identifying patients with ST elevation myocardial infarction (STEMI) from the 12-lead ECG perform with high specificity (SP) but low sensitivity (SE). In our previous studies, we found that the SE of acute ischemia detection can be markedly improved without any loss of SP by calculating, from the 12-lead ECG, ST deviation in 3 "optimal" vessel-specific leads (VSLs). To further validate the method, we evaluated the SP performance using a dataset with non-ischemic ST-segment changes...

BACKGROUND: Vitamin D deficiency has been associated with cardiovascular risk factors, including type 2 diabetes mellitus (T2DM). Evidence shows that patients with low serum 25-hydroxyvitamin D (25OHD) concentrations have a higher risk of developing coronary artery disease. OBJECTIVE: The objective of this study was to assess vitamin D as a predictor of the severity in diabetics with acute coronary syndrome (ACS). METHODS: A total of 166 patients were diagnosed with ACS...

Non-ST segment elevation acute coronary syndrome (NSTE-ACS) can be difficult to diagnose accurately, especially in the hyper-acute phase. Non-ECG-gated contrast-enhanced computed tomography (non-ECG-gated CE-CT) has been used in many institutions for screening acute chest pain. Although early defects (EDs) observed in non-ECG-gated CE-CT have been reported as a sign of acute myocardial ischemia, the precise diagnostic value of this sign for acute coronary syndrome has not been fully elucidated. We investigated the usefulness of non-ECG-gated CE-CT for the diagnosis of NSTE-ACS...

AIMS: Plaque erosion, compared with plaque rupture, has distinctly different underlying pathology and therefore may merit tailored therapy. In this study, we aimed to assess whether patients with acute coronary syndrome (ACS) caused by plaque erosion might be stabilized by anti-thrombotic therapy without stent implantation. METHODS AND RESULTS: This was a single-centre, uncontrolled, prospective, proof-of concept study. Patients with ACS including ST-segment elevation myocardial infarction were prospectively enrolled...
