Characteristics of Takotsubo cardiomyopathy in patients with COVID-19: Systematic scoping review

ABSTRACT:

Background

COVID-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.

Methods

Following 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.

Results

A 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.

Conclusion

This 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:BACKGROUND: Takotsubo cardiomyopathy is a novel, yet well-described, reversible cardiomyopathy triggered by profound psychological or physical stress with a female predominance. OBJECTIVE: This review is designed to increase general clinician awareness about the diagnosis, incidence, pathogenesis, and therapies of this entity. DATA SOURCES: A complete search of multiple electronic databases (Pubmed, EMBASE, Science Citation Index) was carried out to identify all full-text, English-language articles published from 1980 to the present date and relevant to this review. REVIEW METHODS: The following search terms were used: takotsubo cardiomyopathy, stress-induced cardiomyopathy, and left ventricular apical ballooning syndrome. Citation lists from identified articles were subsequently reviewed and pertinent articles were further identified. RESULTS: Takotsubo cardiomyopathy is typically characterized by the following: 1) acute onset of ischemic-like chest pain or dyspnea, 2) transient apical and mid-ventricular regional wall-motion abnormality, 3) minor elevation of cardiac biomarkers, 4) dynamic electrocardiographic changes, and 5) the absence of epicardial coronary artery disease. The pathogenesis of the syndrome is unknown but has mostly been associated with acute emotional or physiologic stressors. Dote, Sato, Tateishi, Uchida, Ishihara (J Cardiol. 21(2):203-214, 1991); Desmet, Adriaenssens, Dens (Heart. 89(9):1027-1031, Sep., 2003); Bybee, Kara, Prasad, et al. (Ann Intern Med. 141(11):858-865, Dec 7, 2004); Sharkey, Lesser, Zenovich, et al. (Circulation. 111(4):472-479, Feb 1, 2005) The short and long-term prognosis of these patients is overwhelmingly favorable and often only requires supportive therapy. CONCLUSION: Whether an emotional or physical event precedes one's symptoms, it is apparent that takotsubo cardiomyopathy case presentations mimic ST-segment elevation myocardial infarction, and thus is an important entity to be recognized by the medical community.

Project description:Background:Myasthenic crisis can induce Takotsubo cardiomyopathy leading to transient systolic and diastolic left ventricular dysfunction and wall-motion abnormalities, including the characteristic apical ballooning. We aimed to define the clinical features of this disease entity. Methods:A systematic review was conducted to examine the characteristics of Takotsubo cardiomyopathy presenting in myasthenia gravis patients. Case reports were accessed by searching MEDLINE/PubMed, Google Scholar, CINAHL, and Web of Science databases. 523 articles were identified and 14 were selected for review. Results:Takotsubo cardiomyopathy presenting in myasthenia gravis' patients tends to affect women between the ages of 40 to 77. History of atrial fibrillation or hypertension was found in a minority of cases. Generalized weakness, fatigue, dysphagia and respiratory distress were common at presentation. Vital signs demonstrated normal blood pressure without tachycardia or bradycardia. Elevated values of troponins, creatine kinase (CK), and CK-MB isoenzymes were recorded. ST-segment elevation followed by T-wave inversion were predominantly found on electrocardiograms. Apical abnormalities in the form of ballooning, hypokinesia, or sparing and reduced left ventricular ejection fraction (?45%) were observed using transthoracic echocardiogram or left ventriculography. Coronary angiography demonstrated no obstructive lesions. Ventilatory support, cholinesterase inhibitors and glucocorticoids resulted in the recovery or improvement of the left ventricular ejection fraction and hemodynamic stability. Only a minority of patients died of refractory heart failure. Treatment with inotropes and/or vasopressors led to poorer outcomes, including death or intractable heart failure. Conclusion:The management of Takotsubo cardiomyopathy developing in myasthenia gravis patients should focus on addressing the myasthenic crisis, while proving supportive care in and intensive care setting.
