| 1 | Takotsubo cardiomyopathy:A comprehensive review显示文摘Takotsubo cardiomyopathy(TCM),also known as stress cardiomyopathy,occurs in the setting of catecholamine surge from an acute stressor.This cardiomyopathy mimics acute myocardial infarction in the absence of coronary disease.The classic feature of TCM is regional wall motion abnormalities with characteristic ballooning of the left ventricle.The etiology of the stressor is often physical or emotional stress,however iatrogenic causes of TCM have been reported in the literature.In our review,we discuss medications,primarily the exogenous administration of catecholamines,and a wide array of procedures with subsequent development of iatrogenic cardiomyopathy.TCM is unique in that it is transient and has favorable outcomes in most individuals.Classically,beta-blockers and ACE-inhibitors have been prescribed in individuals with cardiomyopathy;however,unique to TCM,no specific treatment is required other than temporary supportive measures as this process is transient.Additionally,no improvement in mortality or recurrence have been reported in patients on these drugs.The aim of this review is to elucidate on the iatrogenic causes of TCM,allowing for prompt recognition and management by clinicians. | Walker Barmore Himax Patel Sean Harrell Daniel Garcia Joe B Calkins Jr | 2022 | World Journal of Cardiology2022，14，6： | 2 |
| 2 | Role of cardiac magnetic resonance imaging in the diagnosis and management of COVID-19 related myocarditis: Clinical and imaging considerations显示文摘There is a growing evidence of cardiovascular complications in coronavirusdisease 2019 (COVID-19) patients. As evidence accumulated of COVID-19 mediatedinflammatory effects on the myocardium, substantial attention has beendirected towards cardiovascular imaging modalities that facilitate this diagnosis.Cardiac magnetic resonance imaging (CMRI) is the gold standard for thedetection of structural and functional myocardial alterations and its role inidentifying patients with COVID-19 mediated cardiac injury is growing. Despiteits utility in the diagnosis of myocardial injury in this population, CMRI’s impacton patient management is still evolving. This review provides a framework for theuse of CMRI in diagnosis and management of COVID-19 patients from theperspective of a cardiologist. We review the role of CMRI in the management ofboth the acutely and remotely COVID-19 infected patient. We discuss patientselection for this imaging modality;T1, T2, and late gadolinium enhancementimaging techniques;and previously described CMRI findings in other cardiomyopathieswith potential implications in COVID-19 recovered patients. | Lavannya Atri Michael Morgan Sean Harrell Wael AlJaroudi Adam E Berman | 2021 | World Journal of Radiology2021，13，9： | 1 |
| 3 | COVID-19 vaccine-associated myocarditis显示文摘Myocarditis is now recognized as a rare complication of coronavirus disease 2019(COVID-19)mRNA vaccination,particularly in adolescent and young adult males.Since the authorization of the Pfizer-BioNTech^(TM)and Moderna^(TM)mRNA vaccines targeting the severe acute respiratory syndrome coronavirus-2(SARSCoV-2)spike protein,the Centers for Disease Control and Prevention(CDC)has reported 1175 confirmed cases of myocarditis after COVID-19 vaccination in individuals ages 30 years and younger as of January 2022.According to CDC data in June 2021,the incidence of vaccine-mediated myocarditis in males ages 12-29 years old was estimated to be 40.6 cases per million second doses of COVID-19 mRNA vaccination administered.Individuals with cases of COVID-19 vaccinemediated myocarditis typically present with acute chest pain and elevated serum troponin levels,often within one week of receiving the second dose of mRNA COVID-19 vaccination.Most cases follow a benign clinical course with prompt resolution of symptoms.Proposed mechanisms of COVID-19 vaccine myocarditis include molecular mimicry between SARS-CoV-2 spike protein and self-antigens and the triggering of preexisting dysregulated immune pathways in predisposed individuals.The higher incidence of COVID-19 vaccine myocarditis in young males may be explained by testosterone and its role in modulating the immune response in myocarditis.There is limited data on long-term outcomes in these cases given the recency of their occurrence.The CDC continues to recommend COVID-19 vaccination for everyone 5 years of age and older given the greater risk of serious complications related to natural COVID-19 infection including hospitalization,multisystem organ dysfunction,and death.Further study is needed to better understand the immunopathology and long-term outcomes behind COVID-19 mRNA vaccine-mediated myocarditis. | Michael C Morgan Lavannya Atri Sean Harrell Wael Al-Jaroudi Adam Berman | 2022 | World Journal of Cardiology2022，14，7： | 1 |
