Takotsubo Syndrome in the Setting of COVID-19

JACC: Case Reports, 2020
A 58-year-old woman was admitted with symptoms of coronavirus disease-2019. She subsequently developed mixed shock, and an echocardiogram showed mid-distal left ventricular hypokinesis and apical ballooning, findings typical of stress, or takotsubo ...

Transient Left Ventricular Apical Ballooning [PDF]

Circulation, 2003
A 69-year-old woman presented with acute onset of chest pain and diffuse ST-segment elevation suggesting ischemia (Figure 1). The creatine phosphokinase–MB was elevated, and in view of ongoing chest discomfort, she was referred for urgent cardiac catheterization. Figure 1. Twelve-lead ECG showing normal sinus …

Complete atrioventricular block associated with not apical but midventricular ballooning

, 2013
An 86-year-old woman was admitted to hospital with a head injury secondary to an episode of syncope associated with incontinence. Electrocardiography showed complete atrioventricular block, giant negative T waves in the precordial leads, and QT interval ...

Diltiazem N‐oxide, a novel ischaemia‐activated prodrug, prevents ischaemia‐induced ventricular fibrillation without off‐target adverse effects

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Ventricular fibrillation (VF) in coronary heart disease accounts for up to 70% of sudden cardiac death. We examined whether diltiazem N‐oxide (DNO) has ischaemia‐selective antiarrhythmic activity. Experimental Approach Randomised and blinded experiments were performed in rat isolated hearts and in anaesthetised rats to ...

Estimating the total mortality of seabirds following a marine heat wave

Conservation Biology, EarlyView.
Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.

Basal wall hypercontraction of Takotsubo cardiomyopathy in a patient who had been diagnosed with dilated cardiomyopathy: a case report

BMC Cardiovascular Disorders, 2017
Background Takotsubo cardiomyopathy is characterized by the basal hypercontractility and apical ballooning of the left ventriculum and T-wave inversion in the electrocardiogram.

Persistence without prosperity at the upper range margin: Elevation, microhabitat buffering and biotic pressure in a range‐expanding spider

Ecological Entomology, EarlyView.
Anthropogenic linear features facilitate high‐elevation colonization. Parasitoid pressure declines markedly with elevation. Cocoon damage increases despite reduced parasitism at high elevation. Abstract The upper elevational range limits of thermophilic arthropods reflect constraints on population persistence rather than simple presence.

Unusual combined cause of Takotsubo cardiomyopathy: Hyponatremia and seizure

İstanbul Kuzey Klinikleri, 2019
Takotsubo cardiomyopathy (TTC) is characterized by transient systolic dysfunction of the left ventricle and changes of electrocardiographic or cardiac markers, resembling an acute coronary syndrome.
