Drug induced myocardial infarction is a known entity with different forms of steroids linked to coronary artery disease (CAD) either through promoting its traditional risk factors, inducing coronary spasm, or by other unidentified mechanisms. Dexamethasone is known to promote an atherogenic and hypercoagulable state. We report a case of a 75-year-old woman who had ST elevation myocardial infarction (STEMI) associated with dexamethasone use just 4 days following an angiogram showing minor luminal irregularities.

SummaryPlasma levels of β-thromboglobulin (BTG) and fibrinopeptide A (FPA), markers of platelet release and thrombin generation respectively, were measured in 48 patients within 3 days of admission to hospital for acute chest pain. Twenty-one patients had a confirmed myocardial infarction (MI); 15 had unstable angina without infarction; and 12 had chest pain due to noncardiac causes. FPA and BTG were also measured in 23 control hospital patients of similar age. Mean plasma BTG levels were not significantly different in the 4 groups. Mean plasma FPA levels were significantly higher in all 3 groups with acute chest pain when compared to the control subjects (p < 0.01), but there were no significant differences between the 3 groups. Increased FPA levels in patients with acute chest pain are not specific for myocardial infarction, nor for ischaemic chest pain.

Introduction. Acute myocardial infarction is a clinical manifestation of coronary disease which occurs when a blood vessel is narrowed or occluded in such a way that it leads to irreversible myocardial ischemia. ST segment depression in leads V1?V3 on the electrocardiogram points to the anterior wall ischemia, although it is actually ST elevation with posterior wall myocardial infarction. In the absence of clear ST segment elevation, it may be overlooked, leading to different therapeutic algorithms which could significantly affect the outcome. Case report. A 77 year-old female patient was admitted to the Coronary Care Unit due to prolonged chest pain followed by nausea and horizontal ST segment depression on the electrocardiogram in V1?V3 up to 3 mm. ST segment elevation myocardial infarction of the posterior wall was diagnosed, associated with the development of initial cardiogenic shock and ischemic mitral regurgitation. An emergency coronarography was performed as well as primary percutaneous coronary intervention with stent placement in the circumflex artery, the infarct-related artery. Due to a multi-vessel disease, surgical myocardial revascularization was indicated. Conclusion. Posterior wall transmural myocardial infarction is the most common misdiagnosis in the 12 lead electrocardiogram reading. Routine use of additional posterior (lateral) leads in all patients with chest pain has no diagnostic or therapeutic benefits, but it is indicated when posterior or lateral wall infarction is suspected. The use of posterior leads increases the number of diagnosed ST segment elevation myocardial infarctions contributing to better risk assessment, prognosis and survival due to reperfusion therapy.

Abstract   Both acute aortic dissection (AAD) and acute myocardial infarction (AMI) present with chest pain and are life-threatening diseases that require early diagnosis and treatment for better clinical outcome. However, two critical diseases in the very acute phase are sometimes difficult to differentiate, especially prior to arrival at the hospital for urgent diagnosis and selection of specific treatment. The aim of our study was to clarify the diagnostic markers acquired from the information gathered from medical history taking and physical examination for discriminating AAD from AMI by using data from the Tokyo Cardiovascular Care Unit (CCU) Network database. We examined the clinical features and laboratory data of patients with AAD and AMI who were admitted to the hospital in Tokyo between January 2013 and December 2015 by using the Tokyo CCU Network database. The Tokyo CCU Network consists of &gt;60 hospitals that fulfil certain clinical criteria and receive patients from ambulance units coordinated by the Tokyo Fire Department. Of 15,061 patients diagnosed as having AAD and AMI, 3,195 with chest pain within 2 hours after symptom onset (537 AAD and 2,658 AMI) were examined. The patients with out-of-hospital cardiac arrest were excluded. We compared the clinical data of the patients with chest pain who were diagnosed as having AAD and AMI. The following indicators were more frequent or had higher values among those with AAD: female sex (38% vs. 20%, P&lt;0.001), systolic blood pressures (SBPs) at the time of first contact by the emergency crew (142 mmHg vs. 127 mmHg), back pain in addition to chest pain (54% vs. 5%, P&lt;0.001), history of hypertension (73% vs. 58%, P&lt;0.001), SBP ≥150 mmHg (39% vs. 22%, P&lt;0.001), back pain combined with SBP ≥150 mmHg (23% vs. 0.8%, P&lt;0.001), and back pain with SBP &lt;90 mmHg (4.5% vs. 0.1%, P&lt;0.001). The following data were less frequently observed among those with AAD: diabetes mellitus (7% vs. 28%, P&lt;0.001), dyslipidaemia (17% vs. 42%, P&lt;0.001), and history of smoking (48% vs. 61%, P&lt;0.001). The multivariate regression analysis suggested that back pain with SBP ≥150 mmHg (odds ratio [OR] 47; 95% confidence interval [CI] 28–77; P&lt;0.001), back pain with SBP &lt;90 mmHg (OR 68, 95% CI 16–297, P&lt;0.001), and history of smoking (OR 0.49, 95% CI 0.38–0.63, P&lt;0.001) were the independent markers of AAD. The sensitivity and specificity of back pain with SBPs of ≥150 mmHg and back pain with SBPs &lt;90 mmHg for detecting AAD were 23% and 99%, and 4% and 99%, respectively. In patients with chest pain suspicious of AAD and AMI, “back pain accompanied by chest pain with SBP ≥150 mmHg” or “back pain accompanied by chest pain with SBP &lt;90 mmH” is a reliable diagnostic marker of AAD with high specificity, although the sensitivity was low. The two SBP values with back pain are markers that may be useful for the ambulance crew at their first contact with patients with chest pain. Funding Acknowledgement Type of funding source: None

Abstract Background Myocarditis is an uncommon, potentially life-threatening disease that presents with a wide range of symptoms. In acute myocarditis, chest pain (CP) may mimic typical angina and also be associated with electrocardiographic changes, including an elevation of the ST-segment. A large percentage (20–56%) of myxomas are found incidentally. Case summary A 62-year-old female presenting with sudden onset CP and infero-lateral ST-elevation in the electrocardiogram. The diagnosis of ST-elevation myocardial infarction was presumed and administered tenecteplase. The patient was immediately transported to a percutaneous coronary intervention centre. She complained of intermittent diplopia during transport and referred constitutional symptoms for the past 2 weeks. Coronary angiography showed normal arteries. The echocardiogram revealed moderate to severe left ventricular systolic dysfunction due to large areas of akinesia sparing most of the basal segments, and a mobile mass inside the left atrium attached to the septum. The cardiac magnetic resonance (CMR) suggested the diagnosis of myocarditis with concomitant left atrial myxoma. The patient underwent resection of the myxoma. Neurological evaluation was performed due to mild vertigo while walking and diplopia in extreme eye movements. The head magnetic resonance imaging identified multiple infracentimetric lesions throughout the cerebral parenchyma compatible with an embolization process caused by fragments of the tumour. Discussion Myocarditis can have various presentations may mimic acute myocardial infarction and CMR is critical to establish the diagnosis. Myxoma with embolic complications requires emergent surgery. To the best of our knowledge, this is the first case reported in the applicable literature of a myxoma diagnosed during a myocarditis episode.

We have previously demonstrated that, relative to controls, patients long after myocardial infarction and patients with atherosclerosis have highly significantly shorter heparin thrombin clotting times (HTCT) using platelet poor plasma; but there was considerable overlap between the two groups.We have now studied 89 patients admitted with acute chest pain. In 54 of these a firm diagnosis of acute myocardial infarction (ac-MI) was made and the HTCT was very short (mean 12.8 sees) and in 48 it was less than 16 sees. In 34 patients, ac-MI was excluded and the diagnosis was usually “angina”; the HTCT was much longer (mean 25.1 sees) and in 32 it was over 16 sees. Thus there was almost no overlap between these two groups. It is suggested that this test should be adopted as a quick and reliable further test to establish a diagnosis of ac-MI (providing other reasons for very short HTCTs can be excluded, e.g. D. I. C., and provinding the patient’s thrombin clotting time is normal).This HTCT measures non-specific heparin neutralizing activity; nevertheless the evidence suggests that it is measuring platelet factor 4 liberated from damaged or “activated” platelets into the plasma. These findings underline the probable important contribution of platelets in ac-MI.

Abstract BACKGROUND Rapid and correct diagnosis of acute myocardial infarction (MI) has an important impact on patient treatment and prognosis. We compared the diagnostic performance of high-sensitivity cardiac troponin T (hs-cTnT) and cardiac enriched microRNAs (miRNAs) in patients with MI. METHODS Circulating concentrations of cardiac-enriched miR-208b and miR-499 were measured by quantitative PCR in a case-control study of 510 MI patients referred for primary mechanical reperfusion and 87 healthy controls. RESULTS miRNA-208b and miR-499 were highly increased in MI patients (&gt;105-fold, P &lt; 0.001) and nearly undetectable in healthy controls. Patients with ST-elevation MI (n= 397) had higher miRNA concentrations than patients with non–ST-elevation MI (n = 113) (P &lt; 0.001). Both miRNAs correlated with peak concentrations of creatine kinase and cTnT (P &lt; 10−9). miRNAs and hs-cTnT were already detectable in the plasma 1 h after onset of chest pain. In patients who presented &lt;3 h after onset of pain, miR-499 was positive in 93% of patients and hs-cTnT in 88% of patients (P= 0.78). Overall, miR-499 and hs-cTnT provided comparable diagnostic value with areas under the ROC curves of 0.97. The reclassification index of miR-499 to a clinical model including several risk factors and hs-cTnT was not significant (P = 0.15). CONCLUSION Circulating miRNAs are powerful markers of acute MI. Their usefulness in the establishment of a rapid and accurate diagnosis of acute MI remains to be determined in unselected populations of patients with acute chest pain.
