Madias JE.
PMID: 33300464
Acta Cardiol. 2020 Dec 10;1-9. doi: 10.1080/00015385.2020.1826703. Epub 2020 Dec 10.

OBJECTIVES: Release of norepinephrine (NE) from neuronal cardiac nerve endings and/or blood-borne catecholamines (CATs), mainly epinephrine (EPI), may mediate TTS. The aim of this study was to document the levels of NE, EPI, and dopamine (DA) in patients with...

Front Cardiovasc Med. 2020 Nov 19;7:580296. doi: 10.3389/fcvm.2020.580296. eCollection 2020.

Although heart failure following myocardial infarction (MI) represents a major health burden, underlying microstructural and functional changes remain incompletely understood. Here, we report on a case of unexpected MI after treatment with the catecholamine isoproterenol in an experimental imaging...

Retroperitoneal liposarcomas are rare mesenchymal tumors which carry a poor prognosis because of their late presentation. When symptoms do occur, they are usually nonspecific and related to mass effect or invasion of local structures. Rarely, retroperitoneal liposarcomas can clinically...

Combined neurogenic pulmonary oedema and atypical Takotsubo cardiomyopathy in a patient with ischaemic stroke: a unique case report.

European heart journal. Case reports

Riva L, Casella G, Simonetti L, Zini A.

Eur Heart J Case Rep. 2021 Oct 28;5(11):ytab425. doi: 10.1093/ehjcr/ytab425. eCollection 2021 Nov.

BACKGROUND: Neurogenic pulmonary oedema (NPO) and Takotsubo cardiomyopathy are rare complications of ischaemic stroke. They are considered to be due to an excess catecholamine release after sympathetic nervous stimulation following stroke onset. Among the different types of Takotsubo cardiomyopathy,...

Influential theories postulate distinct roles of catecholamines and acetylcholine in cognition and behavior. However, previous physiological work reported similar effects of these neuromodulators on the response properties (specifically, the gain) of individual cortical neurons. Here, we show a double...
