Chronic management of pulmonary embolism in thromboangiitis obliterans.

Thromboangiitis obliterans (TAO), also known as Buerger's disease, is a rare small vessel vasculitis that is associated with an increased risk of arterial occlusion. Although venous thromboembolism has been described, the risk of its recurrence and the best long-term anticoagulation management is not known. Considering this, we would like to share our experience with two patients admitted to our hospital with recurrent pulmonary embolism and previous diagnosis of TAO, aiming to discuss the indication for indefinite anticoagulation in this population.

Uso de betabloqueador no choque cardiogênico da cardiomiopatia de Takotsubo / Use of beta-blockers in cardiogenic shock due to Takotsubo cardiomyopathy

A cardiomiopatia de Takotsubo se caracteriza por alterações reversíveis na função sistólica e segmentar do ventrículo esquerdo associada à coronariografia normal. O choque associado a essa cardiomiopatia é causado por disfunção sistólica e/ou obstrução dinâmica do trato de saída do ventrículo esquerdo. A identificação da etiologia do choque tem implicações terapêuticas. Relata-se o caso de paciente feminina, 76 anos, com cardiomiopatia de Takotsubo cuja apresentação mimetizou infarto agudo do miocárdio complicado com choque cardiogênico. O choque foi revertido após administração endovenosa de propranolol.

Takotsubo cardiomyopathy is characterized by reversible changes in the systolic and segmental left ventricular function associated with normal coronariography. The shock associated with this cardiomyopathy is caused by left ventricular systolic dysfunction and/or dynamic left ventricular outflow tract obstruction. Identification of the etiology of the shock has implications for treatment. This case study reports on a 76-year-old women diagnosed with Takotsubo cardiomyopathy whose presentation mimicked an acute myocardial infarction complicated by cardiogenic shock. The shock was reversed after intravenous administration of propanolol.
