TAKOTSUBO CARDIOMYOPATHY SECONDARY TO ACUTE BACTERIAL MENINGITIS

Abstract

SESSION TITLE: Medical Student/Resident Critical Care Posters SESSION TYPE: Med Student/Res Case Rep Postr PRESENTED ON: October 18-21, 2020 INTRODUCTION: Infection and sepsis are not uncommon causes of cardiomyopathy due to a decrease in ventricular function. Cardiovascular dysfunction in sepsis can be seen as septic cardiomyopathy, Takotsubo cardiomyopathy, refractory shock or myocardial injury. A study showed that Takotsubo cardiomyopathy was present in 0.15% of admissions with severe sepsis. It should be considered in the differential diagnosis of acute coronary syndrome especially post-menopausal women with preceding stressful events. We present a case of bacterial meningitis leading to Takotsubo’s cardiomyopathy in the setting of CSF leak. CASE PRESENTATION: A 67-year-old woman with no past medical history presented to the emergency department with diarrhea, vomiting, and confusion. On arrival, she was hypotensive to 87/66mmHg, tachycardic 116bpm and hypoxic to 83% on room air. Laboratory evaluation was significant for leukocytosis of 29.2 k/ul, troponin 5.02 ng/ml, lactic acid 2.9 mmol/l, BNP 788 pg/ml. Cerebrospinal fluid showed a white blood cell count of 5011 (91% neutrophils), protein 791 mg/dl, glucose 95 mg/dl. She was admitted with a diagnosis of an NSTEMI, acute meningeal encephalitis and treated with aztreonam, vancomycin, doxycycline, and dexamethasone. Cultures revealed streptococcus viridians and treatment was narrowed to ceftriaxone. Facial CT showed a possible area of dehiscence concern for possible CSF leak. No significant coronary artery disease on the angiogram Echocardiogram was consistent with Takotsubo cardiomyopathy. The patient's cardiomyopathy was treated with goal-directed medical therapy with complete resolution of symptoms. DISCUSSION: Takotsubo cardiomyopathy is defined as a transient regional left ventricular systolic dysfunction without obstructive coronary artery disease and usually triggered by emotional or physical stress. During sepsis, there is an activation of the sympathoadrenergic system with rapid elevation in circulating catecholamine levels. Pathogenesis is related to myocardial stunning, catecholamine toxicity, impaired myocyte metabolism. According to Mayo Clinic criteria there should be: 1) transient hypokinetic, akinesias or dyskinesia of the LV midsegments, 2) absence of CAD, 3) EKG abnormalities or troponin elevation, 4) absence of pheochromocytoma or myocarditis. Patients can present with mild to moderate congestive heart failure or hypotension due to a reduction in stroke volume. The mean age of presentation ranges from around 60 to 75 years. The prognosis is excellent, mortality from 0%-8% and a recurrence occurs in <10% of patients. The treatment is based on the management of the underlying etiology and supportive cardiovascular care. CONCLUSIONS: Patients with suspected TTC need to be work up to rule out ACS with coronary angiogram. Takotsubo’s cardiomyopathy has a good prognosis with recovery on the EF and cardiac function once infection or physical stress disappears.
