Takotsubo cardiomyopathy (TCM), otherwise cardiomyopathy,apical ballooning syndrome or broken heart syndrome is a reversible cardiomyopathy, predominantly occurs in post-menopausal women and commonly due to emotional or physical stress. Typically, patients present with chest pain and ST elevation or T wave inversion on their electrocardiogram mimicking acute coronary syndrome, but with normal or non-flow limiting coronary artery disease. Acute dyspnoea, hypotension and even cardiogenic shock may be the presenting feature of this condition. The wall motion abnormalities typically involve akinesia of the apex of the left ventricle with hyperkinesia of the base of the heart. Atypical forms of TCM have also recently been described. An urgent left ventriculogram or echocardiogram is the key investigation to identify this syndrome. Characteristically, there is only a limited release of cardiac enzymes disproportionate to the extent of regional wall motion abnormality. Transient right ventricular dysfunction may occur and is associated with more complications, longer hospitalisation and worse left ventricular systolic dysfunction. Recently, cardiac MRI has been increasingly used to diagnose this condition and to differentiate from acute coronary syndrome in those who have abnormal coronary arteries. Treatment is often supportive, however beta-blocker and angiotensin-converting enzyme inhibitor or angiotensin II receptor blocking agent are being used in routine clinical practice. The syndrome is usually spontaneously reversible and cardiovascular function returns to normal after a few weeks. This review article will elaborate on the pathophysiology, clinical features including the variant forms, latest diagnostic tools, management and prognosis of this condition.

A 41-year-old man with no significant medical history presented with acute behavioural disruption on the background of a 1-day history of severe headache and a 10-day history of dry cough and fever. He was sexually disinhibited with pressured speech and grandiose ideas. His behaviour worsened, necessitating heavy sedation and transfer to intensive care for mechanical ventilation despite no respiratory indication. Investigations confirmed that he was positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Neuroimaging and a lumbar puncture were normal. Initial screening for SARS-CoV-2 in the cerebrospinal fluid was negative although no validated assay was available. The patient’s mental state remained abnormal following stepdown from intensive care. Psychiatric assessment found features consistent with acute mania, and he was detained under the Mental Health Act. This case indicates the need to consider COVID-19 in a wider series of clinical presentations and to develop a validated assay for SARS-CoV-2 in the cerebrospinal fluid.

Introduction Tako-tsubo cardiomyopathy (TCM) is increasingly being recognised in patients admitted with suspected acute coronary syndrome, as access to angiography and echocardiography are much quicker than before. Typically, patients with TCM present to the primary PCI service (PPCI) with chest pain and ST elevation on their electrocardiogram mimicking ST elevation myocardial infarction (STEMI). However, there is no 'real-world' data about the prevalence of this condition in PPCI admissions for suspected STEMI. Therefore we aimed to analyse the prevalence of TCM in a high volume regional PPCI service in UK. Methods All patients admitted with suspected STEMI between Sept 2009 and Nov 2011 to our centre were included. After excluding those who underwent PPCI, We analysed the echocardiogram and/or left ventriculogram of those patients who did not undergo PPCI to identify patients with typical TCM features of apical akinesia with basal hyperkinesia. Their coronary angiograms were reviewed and the inclusion criteria to identify TCM was the absence of significant coronary disease with no artery having >50% stenosis. Results Of the 1875 patients admitted, 17 (0.9%) patients (0 m, 17 f ) with the mean age of 70±10.7 years (range 56-94 years) were identified to have typical TCM features. The prevalence of TCM in female PPCI admission was 3.1% (17/560) (figure 1). The admission ECG showed ST elevation in 14 patients (82%) and three had LBBB (18%). In those who had positive hsTroponin (n=16, 94.1%), the mean level was 921±668 (median 778, range 110-2550). Two
