Abstract
BACKGROUND: Myocardial dysfunction is common in septic shock and has long been recognized. Takotsubo syndrome is an acute and usually reversible myocardial injury without evidence of an obstructive coronary artery disease, yet little is known about this syndrome in septic shock patients. CASE PRESENTATION: Among 84 septic shock patients admitted to the ICU over a period of 8 months, 7 patients (8.3%) were diagnosed with Takotsubo syndrome. The percentage of men was 71%, and the mean age was 58 (19-87) years. Sudden hemodynamic deterioration and/or dyspnea were the presenting symptoms in 6 patients. T-wave inversion was the major ECG anomaly in 5 patients. The mean left ventricular ejection fraction was 31.8% (20.0-53.0). Mild elevation of cardiac troponin disproportionate to the extent of regional wall motion abnormalities was present in all patients. Cardiac complications occurred in 6 patients. The mean time to recover the cardiac function was 6.5 (3-11) days. In-hospital death was observed in 2 patients. CONCLUSIONS: Takotsubo syndrome is not uncommon in septic shock patients and may be the cause of some patients with sepsis-induced myocardial dysfunction. New-onset hemodynamic and respiratory worsening could arouse the suspicion of Takotsubo syndrome and prompt the screening for this syndrome using echocardiography in this clinical context.
