Abstract
Objective: We report the case of 57-year old woman with no previously known cardiovascular disease. Design and method: Her conventional cardiovascular risk factors were type 2 diabetes (HbA1c< 6.5%), hypertension and active smoking. She presented to the ER for thoracic pain, headache, sweating and tachycardia (150 bpm). Results: Blood analysis showed an elevation of cardiac biomarkers (Troponin 2035ng/l; BNP 541ng/l, Ddimers 19500ug/l), and acute renal impairment (creatinin 158umol/l) while EKG showed inferior NSTEMI. Echocardiography visualized typical takotsubo aspect with apical hypokinesia. Thoraco-abdominal CT-scan showed an important left adrenal tumor. Plasmatic and urinary metanephrine and normetanephrine were high. The patient benefited from adrenal surgery with an optimal result on blood pressure control. Conclusions: Although the association TTS-pheochromocytoma has already been described, it remains uncommon. Catecholamine excessive secretion mediates TTS cardiomyopathy having a negative impact essentially on apical segments increasing wall stress and pressure, but different ventricular segments may be concerned as individual adrenoreceptors distribution patterns vary. TTS diagnosis should legitimate pheochromocytoma screening when associated with labile hypertension.
