Project description:Background and aimsTakotsubo syndrome (TTS), also known as stress cardiomyopathy, is characterized by acute and transient left ventricular dysfunction and has increased during the COVID-19 pandemic. Herein, we aim to review studies on TTS that were associated with COVID-19 infection, vaccine, and other COVID-19-related etiologies including psychosocial stressors.MethodsWe systematically searched PubMed, EMBASE, and Scopus up to May 12, 2022. We included case reports, case series, and original articles that reported at least one TTS case associated with COVID-19, or TTS cases after receiving COVID-19 vaccines, or TTS cases secondary to psychological stress due to the COVID-19 pandemic. The quality assessment was conducted using the Joanna Briggs Institute checklist.ResultsSixty-seven articles including 102 cases were included. Hypertension was the most frequently accompanying comorbidity (N = 67 [65.6%]) and the mean left ventricular ejection fraction was 36.5%. Among COVID-19 patients, the in-hospital mortality rate was 33.3%. On the other hand, only one COVID-19-negative individual expired (2.3%). The most common presenting clinical symptom was dyspnea in 42 (73.6%) patients. the mean time interval from the first symptom to admission was 7.2 days. The most common chest imaging finding was ground-glass opacity which was reported in 14 (31.1%) participants. The most common abnormalities were T-wave inversion in 35 (43.2%) and ST-segment elevation in 30 (37%). Brain natriuretic peptide and troponin were elevated in 94.7% and 95.9% of participants, respectively.ConclusionThe TTS in patients with COVID-19 is almost rare, whereas it could lead to a great mortality and morbidity. An individual with COVID-19, especially an elderly woman, presented with dyspnea in addition to a rise in brain natriuretic peptide and troponin should be evaluated for TTS.
Project description:BackgroundCOVID-19 has recently been associated with the development of Takotsubo cardiomyopathy (TCM). This scoping review aims to summarize the existing evidence regarding TCM in COVID-19 and offer future direction for study.MethodsFollowing the PRISMA Extension for Scoping Reviews, MEDLINE and EMBASE were searched for all peer-reviewed articles with relevant keywords including "Takotsubo", "Stress-induced cardiomyopathy" and "COVID-19" from their inception to September 25, 2021.ResultsA total of 40 articles with 52 cases were included. Patients with TCM and COVID-19 showed only slight female predominance (59.6%), median age of 68.5 years, and were mostly of the apical subtype (88.6%). All-cause mortality was 36.5%. The median LVEF was 30%. Compared to those without TCM, those with TCM in COVID-19 had more critical illness, higher mortality, lower LVEF, and higher cardiac and inflammatory biomarkers. Notably, the diagnostic criteria of TCM were considerably different between case reports and observational studies.ConclusionThis scoping review identifies that TCM in COVID-19 may have distinct features that distinguish this condition from TCM without COVID-19. Future studies are warranted to help describe risk factors, determine the utility of inflammatory biomarkers and serum catecholamine levels, and establish disease-specific diagnostic criteria.
Project description:AimsTo perform a systematic review assessing the clinical manifestations and outcomes of cardiorenal syndrome or the presence of both cardiac and renal complications in the 2019 coronavirus disease (COVID-19) patients.MethodsAll relevant studies about cardiorenal syndrome or both cardiac and renal complications in COVID-19 patients were retrieved on PUBMED, MEDLINE, and EMBASE from December 1, 2019 to February 20, 2022.ResultsOur search identified 15 studies including 637 patients with a diagnosis of cardiorenal syndrome or evidence of both cardiac and renal complications followingSARS-CoV-2 infection. They were male predominant (66.2%, 422/637), with a mean age of 58 years old. Cardiac complications included myocardial injury (13 studies), heart failure (7 studies), arrhythmias (5 studies), or myocarditis and cardiomyopathy (2 studies). Renal complications manifested as acute kidney injury with or without oliguria. Patients with cardiorenal injury were often associated with significantly elevated levels of inflammatory markers (CRP, PCT, IL-6). Patients with a diagnosis of cardiorenal syndrome or evidence of both cardiac and renal complications had more severe disease and poorer prognosis (9 studies).ConclusionThe presence of either cardiorenal syndrome or concurrent cardiac and renal complications had a significant impact on the severity of the disease and the mortality rate among patients with COVID-19 infection. Therefore, careful assessment and management of potential cardiac and renal complications in patients with COVID-19 infection are important to improve their outcomes.
Project description:We completed a systematic review of Takotsubo syndrome (TTS) cases reported during the coronavirus disease 2019 (COVID-19) pandemic and performed clustering and feature importance analysis and statistical testing for independence on the demographic, clinical, and imaging parameters. Compared with the data before the COVID-19 pandemic, TTS was increasingly diagnosed in physical stress (mostly COVID-19 pneumonia)-triggered male patients without psychiatric/neurologic disorders, warranting further investigation to establish new reference criteria to improve diagnostic specificity. In clustering analysis, sex and inpatient mortality primarily contributed to the automated classification of the TTS. Both sex and inpatient mortality had essential correlations with COVID-19 infection/pneumonia. There is effect modification of sex on outcomes in patients with COVID-19 infection and TTS, with male patients having significantly worse inpatient mortality. Meanwhile, significantly more male patients with TTS were classified as high risk according to International Takotsubo Registry prognostic scores, suggesting that male COVID-19/TTS survivors will likely have worse long-term outcome.
Project description:IntroductionDown syndrome (DS) is associated with multiple comorbid conditions and chronic immune dysfunction. Persons with DS who contract COVID-19 are at high risk for complications and have a poor prognosis. We aimed to study the clinical symptoms, laboratory and biochemical profiles, radiologic findings, treatment, and outcomes of patients with DS and COVID-19.MethodWe systematically searched PubMed, MEDLINE, Web of Science, Scopus, and the Cochrane Library using the keywords COVID-19 or coronavirus or SARS-CoV-2 and DS or trisomy 21. Seventeen articles were identified: eight case reports and nine case series published from December 2019 through March 2022, with a total of 55 cases.ResultsPatients averaged 24.8 years (26 days to 60 years); 29 of the patients were male. The most common symptoms were fever, dyspnea, and cough. Gastrointestinal and upper respiratory tract symptoms were commonly reported for pediatric patients. The most common comorbidities present in patients with DS were obesity (49.0%), hypothyroidism (21.6%) and obstructive sleep apnea (15.6%). The patients were hospitalized for a mean of 14.8 days. When the patients were compared with the general COVID-19 population, the mean number of hospitalized days was higher. Most patients had leukopenia, lymphopenia, and elevated inflammatory markers (d-dimer and C-reactive protein). Bilateral infiltrations and bilateral ground-glass opacifications were frequently seen in chest radiographs and chest computed tomographic imaging. Most of the patients were treated with methylprednisolone, macrolides, and hydroxychloroquine. Of the 55 patients, 22 died. The mean age of the patients who died was 42.8 years. Mortality rate was higher in individuals with DS over 40 years of age.ConclusionMore studies are needed to better understand COVID-19 infections among persons with DS. In addition, the study was limited by a lack of statistical analyses and a specific comparison group.
Project description:Takotsubo syndrome (TTS) is a rare cardiovascular condition characterized by reversible ventricular dysfunction and a presentation resembling that of acute myocardial infarction. An increasing number of studies has shown the association of respiratory diseases with TTS. Here, we comprehensively reviewed the literature and examined the available evidence for this association. After searching PubMed, EMBASE, and Cochrane Library databases, two investigators independently reviewed 3117 studies published through May 2021. Of these studies, 99 met the inclusion criteria (n = 108 patients). In patients with coexisting respiratory disease and TTS, the most common TTS symptom was dyspnoea (70.48%), followed by chest pain (24.76%) and syncope (2.86%). The most common type of TTS was apical, accounting for 81.13% of cases, followed by the midventricular (8.49%), basal (8.49%), and biventricular (1.89%) types. Among the TTS cases, 39.82% were associated with obstructive lung disease and 38.89% were associated with pneumonia. Coronavirus disease 2019 (COVID-19), which has been increasingly reported in patients with TTS, was identified in 29 of 42 (69.05%) patients with pneumonia. The overall mortality rate for patients admitted for respiratory disease complicated by TTS was 12.50%. Obstructive lung disease and pneumonia are the most frequently identified respiratory triggers of TTS. Medications and invasive procedures utilized in managing respiratory diseases may also contribute to the development of TTS. Furthermore, the diagnosis of TTS triggered by these conditions can be challenging due to its atypical presentation. Future prospective studies are needed to establish appropriate guidelines for managing respiratory disease with concurrent TTS.
Project description:Coronavirus disease 2019 (COVID-19) has been shown to affect the cardiovascular system, and several cases of takotsubo syndrome (TTS) induced by COVID-19 have been reported. TTS predominantly affects postmenopausal women in western countries, but the prevalence in men is higher in Asian populations. It should be noted that male patients with either TTS or COVID-19 are associated with higher mortality. Despite the higher prevalence of TTS in Asian men, little is known about Asian men with TTS induced by COVID-19. This is a case report of a 60-year-old Asian male with biventricular TTS precipitated by COVID-19. He presented with acute respiratory distress syndrome, cardiogenic shock, and acute kidney injury. He required intubation, multiple vasopressors, and renal replacement therapy. The left ventricular ejection fraction was 15%, but it normalized in 5 weeks. The patient had a prolonged hospital stay in a critical condition, but was eventually discharged alive. The scarce literature about this condition in Asian male populations and the increasing number of COVID-19 cases in Asian countries highlight the rarity and importance of this case. Further studies are warranted to investigate the uneven sex distribution and outcomes of TTS triggered by COVID-19 in an Asian population. <Learning objective: Takotsubo syndrome (TTS) can be provoked by coronavirus disease 2019 (COVID-19). Male sex, right ventricular dysfunction, and COVID-19 as a trigger, are important predicting factors for worse prognosis. It is unknown if there is a significant racial difference in the sex distribution and outcomes for this condition. Further studies are warranted to investigate TTS triggered by COVID-19 in an Asian population.>.
Project description:BackgroundMyasthenia gravis associated takotsubo syndrome is a rare condition. This study aimed to explore its typical presentation, investigations and treatment through a systematic review of previously reported cases.MethodsDatabases and reference lists of the selected articles were searched for case reports on Myasthenia gravis associated takotsubo syndrome. CARE guidelines were used for the quality assessment of the selected articles.ResultsSixteen cases were selected out of 580 search results. Western Pacific, American and European regions contributed to 88% of the cases. Females were most affected (81%). Features of both myasthenia gravis and takotsubo syndrome were the common clinical presentations. All cases had a myasthenic crisis. Half of the cases had no prior diagnosis of myasthenia gravis. Pyridostigmine and prednisolone were useful for myasthenia gravis while dobutamine was most commonly used for takotsubo syndrome. All cases survived except four (25%).ConclusionsMyasthenia gravis associated takotsubo syndrome via a myasthenic crisis is rare but life-threatening. Therefore, predisposition due to emotional and physical triggers needs to be avoided for its prevention. The rare entity should be suspected even in patients without a prior diagnosis of Myasthenia gravis.
