SHDA Research Update – November 2017

Welcome to the monthly SHDA Research Update. Our specialists have selected 3 seminal papers that have been recently published in each speciality (Cardiology, Cardiac Surgery, Cardiac Imaging, Perioperative Medicine).   Cardiology Summarised by Sarah Catchpoole Scally C, et al. Persistent Long-Term Structural, Functional, and Metabolic Changes After Stress-Induced (Takotsubo) Cardiomyopathy. Circulation. 2017 Nov 11. This study challenges the common perception that Takasubo cardiomyopathy is a self-limiting condition. Rather, the authors found persisting impairments, all consistent with a long-term heart failure phenotype. Of 37 patients with a prior diagnosis of Takasubo cardiomyopathy (minimum >12 months, range 13–39, median 20), 88% reported persistent symptoms...
