Metformin preconditioning protects against myocardial stunning and preserves protein translation in a mouse model of cardiac arrest

Journal of Molecular and Cellular Cardiology Plus, 2023
Cardiac arrest (CA) causes high mortality due to multi-system organ damage attributable to ischemia-reperfusion injury. Recent work in our group found that among diabetic patients who experienced cardiac arrest, those taking metformin had less evidence ...

Myocardial stunning in the neonate

British Journal of Anaesthesia, 1998
the normally oxygenated heart. 9 Myocardial stunning is caused by myocyte dysfunction. Generation of free radicals, resulting in damage to cellular proteins and phospholipids, and disruption of intracellular calcium homeostasis, are the two, non-mutually exclusive mechanismsesponsible forhisost- injury dysfunction.

Prominent J-wave and T-wave alternans associated with mechanical alternans in a patient with takotsubo cardiomyopathy

Journal of Arrhythmia, 2015
A 74-year-old woman with takotsubo cardiomyopathy developed polymorphic ventricular tachycardia during the acute phase. She exhibited prominent J-wave and T-wave alternans preceding ventricular tachycardia.

Takotsubo Syndrome: A Review of Presentation, Diagnosis and Management

Clinical Medicine Insights: Cardiology, 2022
Takotsubo Syndrome (TTS) is a condition of transient left ventricular dysfunction that is typically triggered by emotional or physical stress. Since first described in Japan in 1990, it has increasingly been recognised in clinical practice, accounting ...

Comparison of the proteomic landscape in experimental ischemia reperfusion with versus without ischemic preconditioning

Scientific Reports
Myocardial ischemic preconditioning (IPC) enhances myocardial resilience to ischemic injury. Myocardial stunning is a transient, reversible dysfunction, while necrosis involves irreversible cell death. The relationship between IPC, stunning, and necrosis

Evaluation of stunned and infarcted canine myocardium by real time myocardial contrast echocardiography

Brazilian Journal of Medical and Biological Research, 2003
Differentiation between stunned and infarcted myocardium in the setting of acute ischemia is challenging. Real time myocardial contrast echocardiography allows the simultaneous assessment of myocardial perfusion and function.

Takotsubo cardiomyopathy after microwave ablation of hepatocellular carcinoma

Radiology Case Reports, 2023
Takotsubo cardiomyopathy is a form of stress cardiomyopathy that can clinically mimic an acute ST-segment elevation myocardial infarction (STEMI). It involves transient anomalies in left ventricular wall motion secondary to myocardial stunning.

Endothelial Dysfunction and Vascular Preconditioning

Journal of Biological Research, 2003
The prolonged occlusion of a coronary artery followed by reperfusion causes deleterious effects known as “ischemiareperfusion injuries”. In fact, these injuries,which affect both myocardium and coronary endothelium, initiate during ischemia and worsen ...
