Type A acute aortic dissection (AAD) is a serious cardiovascular emergency requiring urgent surgery. Timely accurate diagnosis is essential, but often challenging, because of the wide spectrum of clinical presentations. In patients with type A AAD, chest pain is the most common symptom; furthermore, ischemic ST-T changes such as ST-segment elevation or depression or negative T waves are frequently observed on presentation ECG. These clinical presentations of type A AAD are difficult to differentiate from those of acute coronary syndrome (ACS), which could lead to delayed diagnosis and treatment of type A AAD or misdiagnosis of ACS followed by inappropriate treatment...

BACKGROUND/PURPOSE: The neutrophil/lymphocyte ratio (NLR) has been proposed as a prognostic marker in acute myocardial infarction (AMI). The aim of our study is to demonstrates the correlation between SYNTAX score (SXs) and NLR and its association with 1-year cardiovascular (CV) mortality in patients with ST-segment elevation myocardial infarction (STEMI) or non-ST-segment elevation myocardial infarction (NSTEMI) treated with percutaneous coronary intervention (PCI). METHODS/MATERIALS: Over 6 consecutive years, (1st January 2010 and 1st January 2016) 6560 patients (4841 males and 1719 females, mean age 64...

BACKGROUND: Patients with Brugada syndrome (BrS) are diagnosed and risk stratified on the basis of a spontaneous or drug-induced type 1 electrocardiographic (ECG) pattern, often at single time points not accounting for variation throughout the day. OBJECTIVES: The purpose of this study was to prospectively assess the overall burden of type 1 Brugada ECG changes using 12-lead 24-hour Holter monitoring and evaluate association with cardiac events. METHODS: From July 1, 2013 to December 31, 2015, patients with BrS were recruited from 3 Australian centers and the Australian Genetic Heart Disease Registry...

OBJECTIVES: The aim of this study was to compare bivalirudin with heparin as anticoagulant agents in patients with ST-segment elevation myocardial infarction treated with radial primary percutaneous coronary intervention (PCI). BACKGROUND: Recent studies in which PCI was performed predominantly via radial access did not show bivalirudin to be superior to heparin. METHODS: Outcomes were compared in patients with STEMI included in the National Cardiovascular Data Registry CathPCI database from 2009 to 2015 who underwent primary PCI via radial access and who were anticoagulated with bivalirudin or heparin...

Acute coronary syndromes (ACS) frequently occur in elderly subjects. The high mortality associated with ACS in this population justifies the identification of factors related to poor prognosis. We aimed to evaluate the short-term prognostic performance of the SYNTAX score in a population of patients aged 85years or more presenting ACS and undergoing coronary angiography. Secondary objectives were to identify factors related to length of stay and potential markers of in-hospital death. We performed a retrospective, single-centre prognostic study including patients aged 85years or more who underwent coronary angiography for ACS over a 4year period...

Prediction of coronary events remains elusive. Carotid atherosclerosis may be a surrogate for coronary risk, as carotid and coronary diseases occur simultaneously - albeit at times with a weak association - depending on clinical presentation. We investigated carotid and coronary atherosclerosis in men with new-onset unstable coronary artery disease (CAD) presenting with acute ST-segment elevation myocardial infarction (STEMI) vs. long-standing severe chronic stable angina (CSA). Bilateral carotid artery and 3-vessel coronary artery atherosclerosis burdens were measured within 1 month, respectively, by 3D-volumetric carotid magnetic resonance imaging and coronary angiography-derived modified CASS-50 score...

BACKGROUND: Extra corporeal life support (ECLS) is presently first line therapy for refractory cardiogenic shock. Mobile circulatory support teams implant ECLS or extra corporeal membrane oxygenation (ECMO) in patients in the hospital without circulatory support. These patients are then transported to specialized centers. Here we report a case of sending a mobile circulatory support team abroad, followed by air ambulance evacuation, which, to our knowledge, has never been used as part of medical assistance abroad...

Elderly patients with an acute coronary syndrome are underrepresented in randomised controlled trials. Neither the European Society of Cardiology nor the American Heart Association/American College of Cardiology acute coronary syndrome guidelines provide specific recommendations for elderly patients. However, elderly patients are at higher thrombotic and bleeding risk compared with younger patients leading to difficulties in choosing the optimal treatment. In this review, we discuss the uncertainties we encounter in treating elderly patients with non-ST-elevation acute coronary syndrome and suggest treatment options based on the existing literature...

Nuclear factor erythroid 2 related factor 2 (Nrf2) signaling maintains the redox homeostasis and its activation is shown to suppress cardiac maladaptation. Earlier we reported that acute endurance exercise (2 days) evoked antioxidant cytoprotection in young WT animals but not in aged WT animals. However, the effect of repeated endurance exercise during biologic aging (WT) characterized by an inherent deterioration in Nrf2 signaling and pathological aging (pronounced oxidative susceptibility-Nrf2 absence) in the myocardium remains elusive...

BACKGROUND: Remote ischemic conditioning (RIC) is a noninvasive therapeutic strategy that uses brief cycles of blood pressure cuff inflation and deflation to protect the myocardium against ischemia-reperfusion injury. The objective of this systematic review was to determine the impact of RIC on myocardial salvage index, infarct size, and major adverse cardiovascular events when initiated before catheterization. METHODS AND RESULTS: Electronic searches of Medline, Embase, and Cochrane Central Register of Controlled Trials were conducted and reference lists were hand searched...

BACKGROUND: There are conflicting data on whether changes in N-terminal pro-B-type natriuretic peptide (NT-proBNP) and high-sensitivity C-reactive protein (hs-CRP) concentrations between time points (delta NT-proBNP and hs-CRP) are associated with a change in prognosis. METHODS: We measured NT-proBNP and hs-CRP at 3 time points in 1665 patients with non-ST-segment elevation acute coronary syndrome (NSTEACS). Cox proportional hazards was applied to the delta between temporal measurements to determine the continuous association with cardiovascular events...

BACKGROUND: Severe malaria anemia is a major cause of childhood heart failure in malaria endemic countries. The resulting hypoxic-ischemic injuries may cause myocardial damage detectable by electrocardiogram (ECG) and elevated troponin T (cTnT) levels. OBJECTIVE: Evaluate the ECG changes and cTnT levels in children with severe malaria anemia compared with those who had uncomplicated malaria without anemia. METHODS: Consecutive children with severe malaria anemia were recruited as subjects while controls were age- and gender-matched children with uncomplicated malaria without anemia...

Spontaneous coronary artery dissection (SCAD) is a well-known but infrequent cause of acute coronary syndrome (ACS), and often goes unrecognized. Although management of SCAD is, at times, controversial, when a patient presents with ACS, percutaneous coronary intervention (PCI) is frequently necessary. We present a patient with ST-segment elevation myocardial infarction (STEMI) with SCAD that illustrates two important points: use of intracoronary optical coherence tomography to guide PCI, and histologic assessment to provide a unique insight into the etiology of SCAD...

BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) presenting with ST-segment elevation myocardial infarction (STEMI) are less likely to beneficiate of primary percutaneous coronary intervention (pPCI), and have poorer prognosis. We aimed to evaluate the impact of COPD on the in-hospital outcomes of pPCI-treated STEMI patients. METHODS: Data were collected from 418 STEMI patients treated by pPCI. Inotropics and diuretics usage, cardiogenic shock, asystole, kidney dysfunction, and left ventricular ejection fraction were used as markers of hemodynamic complications...
