We report a 54-year-old woman with scorpion bite. After 3 hours of admission, the patient developed sudden onset tachycardia with hypotension. Cardiac evaluation showed raised creatine kinase MB isoenzyme was elevated; ECG and two-dimensional echocardiography findings were suggestive of myocarditis. Subsequently, she developed transient ventricular tachycardia before developing abrupt onset, right hemiplegia, global aphasia and progressive worsening of sensorium 12 hours after the bite. MRI of brain revealed massive left middle cerebral artery (MCA) territory infarct...

Chest pain is a typical symptom of acute myocarditis in adolescents. It may be indistinguishable from myocardial ischemia so it is called "infarct-like pattern." Cardiovascular magnetic resonance has an important role as a non-invasive diagnostic tool. The aim of our study is to provide a description of an acute myocarditis series with infarct-like pattern and to evaluate the cardiovascular magnetic resonance role in a pediatric population. We included all pediatric patients (0-16 years) admitted to our hospital (May 2007-May 2016) with clinical diagnosis of acute myocarditis and infarct-like presentation (chest pain, EKG alterations, and released cardiac biomarkers)...

Loss of cardiomyocytes occurs with aging and contributes to cardiovascular complications. In the present study, we highlighted the role of clusterin, a protein that has recently been associated with the protection of cardiomyocytes from apoptosis. Clusterin protects cardiac cells against damage from myocardial infarction, transplant, or myocarditis. Clusterin can act directly or indirectly on apoptosis by regulating several intracellular pathways. These pathways include (1) the oxidant and inflammatory program, (2) insulin growth factor 1 (IGF-1) pathway, (3) KU70 / BCL-2-associated X protein (BAX) pathway, (4) tumor necrosis factor alpha (TNF-α) pathway, (5) BCL-2 antagonist of cell death (BAD) pathway, and (6) mitogen-activated protein kinase (MAPK) pathway...

Background Accurate diagnosis of cardiovascular involvement in systemic lupus erythematosus (SLE) remains challenging, due to limitations of echocardiography. We hypothesized that cardiovascular magnetic resonance can detect cardiac lesions missed by echocardiography in SLE patients with atypical symptoms. Aim To use cardiovascular magnetic resonance in SLE patients with atypical symptoms and investigate the possibility of silent heart disease, missed by echocardiography. Patients/methods From 2005 to 2015, 80 SLE patients with atypical cardiac symptoms/signs (fatigue, mild shortness of breath, early repolarization and sinus tachycardia) aged 37 ± 6 years (72 women/8 men), with normal echocardiography, were evaluated using a 1...

AIMS: Poor data exist about cardiac magnetic resonance (CMR) findings in a large sample of acute myocarditis with different clinical presentations (heart failure, arrhythmias, and infarct-like presentation). METHODS: Five hundred and forty-three in-patients with a clinical suspected of acute myocarditis confirmed by CMR were enrolled. The clinical indications to perform CMR were chest pain and/or dyspnea and/or palpitations, or effort intolerance/malaise in the last month; elevated troponin and/or new ventricular dysfunction, and/or new ECG abnormalities; and suspected inflammatory cause...

Myocarditis is an inflammation of the myocardium. Clinical presentation ranges from non-specific systematic symptoms to fulminant collapse and sudden death. Sudden death occurs at rates of 8.6-12% and cardiomyopathy at 9%. In active myocarditis, there is inflammatory cellular infiltrate with myocardial necrosis. The disease is distinguished by clinical presentation in fulminant and non-fulminant myocarditis. We present a rare case of a parvovirus B19-induced fulminant viral myocarditis in a young female. The patient presented with acute onset heart failure mimicking a myocardial infarction, followed by non-specific symptoms that had been misdiagnosed as urinary tract infection...

AIMS: Retinoic acid receptor-related orphan nuclear receptor γt (RORγt) is a transcriptional factor responsible for IL-17-producing T-cell differentiation. Although it was demonstrated that RORγt plays essential roles in the onset of autoimmune myocarditis, pathophysiological significance of RORγt in cardiac remodeling after myocardial infarction (MI) remains to be fully elucidated. METHODS AND RESULTS: MI was generated by ligating coronary artery. The expression of RORγt and IL-17A transcripts increased in murine hearts after MI...

The increasing use of cardiovascular magnetic resonance (CMR) is based on its capability to perform biventricular function assessment and tissue characterization without radiation and with high reproducibility. The use of late gadolinium enhancement (LGE) gave the potential of non-invasive biopsy for fibrosis quantification. However, LGE is unable to detect diffuse myocardial disease. Native T1 mapping and extracellular volume fraction (ECV) provide knowledge about pathologies affecting both the myocardium and interstitium that is otherwise difficult to identify...

We report the case of an 18-year-old woman with personality disorders who was hospitalized a few hours after suicidal ingestion of acetaminophen, quetiapine, acetylsalicylic acid, and ethanol. Twelve hours after admission, severe liver damage was evident, but the patient was stable and awaiting hepatic transplantation. Electrolytes were successfully controlled. The condition of the liver stabilized. Cardiac biomarkers then deteriorated unexpectedly. Localized ST-segment elevations were noted on electrocardiogram, but angiography ruled out myocardial infarction...

In this female patient eosinophilic myocarditis was complicated by myocardial rupture and hemopericardium with cardiac tamponade. Special features of this case were old age of the patient, fulminant course of the disease, myocardial infarction-like ECG changes, absence of peripheral blood eosinophilia. Presentation is accompanied by discussion of issues of epidemiology, clinical course, diagnostics, and possible causes of eosinophilic myocarditis.

We present a case of a 21-year-old man presenting with sharp left-sided chest pain. A CT pulmonary angiogram was negative, ECG was unremarkable and a mild troponin rise was observed. Myocarditis was suspected as the most likely diagnosis, particularly in view of the patient's previous diagnosis of myocarditis 3 years prior. A cardiac MRI was indicative of an acute mid-anterior myocardial infarction (MI) and an old inferior MI with an associated aneurysm. A subsequent angiogram revealed a subtotal occlusion in the second diagonal artery, likely precipitated by homozygous factor V Leiden...

Lyme disease is caused by the spirochete Borrelia burgdorferi and is carried to human hosts by infected ticks. There are nearly 30,000 cases of Lyme disease reported to the CDC each year, with 3-4% of those cases reporting Lyme carditis. The most common manifestation of Lyme carditis is partial heart block following bacterial-induced inflammation of the conducting nodes. Here we report a 45-year-old gentleman that presented to the hospital with intense nonradiating chest pressure and tightness. Lab studies were remarkable for elevated troponins...

PURPOSE: Chronic diabetes is associated with cardiovascular dysfunctions. Diabetic cardiomyopathy (DCM) is one of the serious cardiovascular complications associated with diabetes. Despite significant efforts in understanding the pathophysiology of DCM, management of DCM is not adequate due to its complex pathophysiology. Recently, involvement of protease-activated receptors (PARs) has been postulated in cardiovascular diseases. These receptors are activated by thrombin, trypsin, or other serine proteases...
