Serum and plasma myoglobin and creatine kinase-MB catalytic activity were analysed in 157 patients admitted within 2 hours of the onset of chest pain (58 were retrospectively recognized as acute myocardial infarction). Serum and plasma values were highly correlated for both myoglobin and creatine kinase-MB. Plasma myoglobin appeared to be more sensitive than creatine kinase-MB for the early dia...

INTRODUCTION AND OBJECTIVES The role of high-density lipoproteins in the context of acute chest pain has not been well characterized. The objective of this study was to determine the relative contribution of lipid profile to the risk of acute coronary syndrome in patients admitted to a cardiology ward for chest pain. METHODS We included all consecutive admissions in a single cardiology depart...

BACKGROUND Acute chest pain is a frequently occurring symptom in patients with medical emergencies and imposes potentially life threatening situations outside hospitals. Little is known about the epidemiology of patients with acute chest pain in a primary care setting in Norway, and we aimed to obtain more representative data on such patients using data from emergency medical communication cent...

The acute occlusion of a coronary artery without the evidence of myocardial infarction might immediately affect both the diagnosis and treatment of coronary artery disease. We present the case with a sudden occlusion of the left main coronary artery without typical chest pain following an exercise tolerance test and rapid spontaneous reperfusion of the left main coronary artery.

UNLABELLED INTRODUCTION AND OBJECTIVES. To study the significance of chest pain in the clinical practice of a Spanish hospital and to evaluate the impact of routine troponin determination. METHODS In our institution, routine serial measurements of troponins I and T were made in the evaluation of chest pain in 2000. We compared the results obtained in 1999 for all patients who visited the emer...

CONTEXT The chest pain history, physical examination, determination of coronary artery disease (CAD) risk factors, and the initial electrocardiogram compose the information immediately available to clinicians to help determine the probability of acute myocardial infarction (AMI) or acute coronary syndrome (ACS) in patients with chest pain. However, conflicting data exist about the usefulness of...

AIMS The aim of this study was to compare in patients presenting with acute chest pain the clinical outcomes and cost-effectiveness of an accelerated diagnostic protocol utilizing contemporary technology in a chest pain unit versus routine care in an internal medicine department. METHODS AND RESULTS Hospital and 90-day course were prospectively studied in 585 consecutive low-moderate risk acu...

This review highlights an important novel aspect of the 2011 ESC guidelines for the management of acute coronary syndromes in patients presenting without persistent ST-segment elevation: the recommendations of a rapid rule-out protocol (0h and 3h) when high-sensitive cardiac troponin assays are available. The controversy relates to the scientific question how reliably patients can recall the on...

Introduction and objectives. We investigated the usefulness of taking two serial measurements of the highsensitivity C-reactive protein (hs-CRP) level for evaluating acute chest pain in patients with non-diagnostic ECG findings and normal levels of markers of myocardial cell injury (ie, an inconclusive diagnosis). We hypothesized that the C-reactive protein concentration would be raised if symp...

discussion hydatid cyst in pericardium represents only 0.5-2% of cases of systemic echinoccocal infection. isolated pericardial cyst is very rare in endemic region and may present mimicking acute coronary syndrome. cardiac hydatid cysts should always be considered in presence of eosinophilia as present like acute coronary syndrome in endemic area. introduction hydatid cysts are most commonly fo...
