Stunned Myocardium in the Toxic Shock Syndrome

Update on the COVID‐19‐associated inflammatory syndrome in children and adolescents; paediatric inflammatory multisystem syndrome‐temporally associated with SARS‐CoV‐2

“…In Australia and New Zealand, where community transmission and incidence of SARS-CoV-2 remains low, there has not been any change in expected KD incidence in 2020 to date in as yet unpublished national surveillance data (http://www.paeds.org.au/ covid-19-kawasaki-disease-kd-and-pims-ts-children). 17 Both cardiogenic and distributive shock reported frequently 20,23,30 Reported, but distributive shock predominates 31,32 Ventricular function abnormality in 31% 9 or 7/8. 13 Between 40 and 62% with shock had impaired EF 7,9 Laboratory findings Total leukocyte count N/" 9,18,26 " 9,26 N/" 9,21 N/# 7,9 Neutrophil count N/" 9,18,26 " 9,26 N/" 9,21 N/" 7,9 Lymphocyte count N 9,18 N 9 """ 9,28 ## 7,9 Haemoglobin N/# 9,26 N/# 9,26 # 9,21,28 # 7,9 Platelet count N, "" in 2nd-3rd week 18 # in severe cases 18 ", however # more common than in KD 9,21,27…”

Sepsis-induced Cardiomyopathy

“…During the SIMD both ventricles can dilate and diminish its ejection fraction, having less response to fluid resuscitation and to increase CO despite starting treatment with catecholamines. The degree of SIMD is very variable, ranging from mild to severe [26, 27]. Sometimes the degree of myocardial depression may be so severe that imitates a cardiogenic shock [28], but typically is assumed to be reversible within 7-10 days [21, 29, 30] (Figures 1-2 ).…”

Successful Use of Extracorporeal Membrane Oxygenation in an Adult Patient With Toxic Shock-Induced Heart Failure

“…7 Crews et al performed myocardial biopsy of a patient with severe TSS, and concluded that heart failure in these patients is produced by direct myocardial suppression caused by a Staphylococcal toxin. 8…”
