Myocardial stunning in hyperthyroidism [PDF]

Clinical Cardiology, 2000
AbstractThe cases of two patients with hyperthyroidism and acute left ventricular (LV) dysfunction with segmental wall motion abnormalities resulting in heart failure are reported. Both had electrocardiographic changes mimicking ischemic coronary artery disease.

Changes in Global Left Ventricular Myocardial Work Indices and Stunning Detection 3 Months After ST-Segment Elevation Myocardial Infarction.

American Journal of Cardiology, 2021
Global left ventricular (LV) myocardial work (MW) indices (GLVMWI) are derived from speckle tracking echocardiographic strain data in combination with non-invasive blood pressure measurements. Changes in global work index (GWI), global constructive work (

Q50, an Iron-Chelating and Zinc-Complexing Agent, Improves Cardiac Function in Rat Models of Ischemia/Reperfusion-Induced Myocardial Injury [PDF]

, 2013
Background: Reperfusion of ischemic myocardium may contribute to substantial cardiac tissue damage, but the addition of iron chelators, zinc or zinc complexes has been shown to prevent heart from reperfusion injury.

The effectiveness and cost-effectiveness of computed tomography screening for coronary artery disease : systematic review [PDF]

, 2006
Coronary heart disease (CHD) is one of the main causes of mortality and morbidity in the UK and other Western countries. The disease can be asymptomatic until the first event, which may be a fatal myocardial infarction (heart attack).

Brief Myocardial Ischemia Produces Cardiac Troponin I Release and Focal Myocyte Apoptosis in the Absence of Pathological Infarction in Swine

JACC: Basic to Translational Science, 2017
Summary: In a porcine model of brief ischemia leading to reversible stunning in the absence of tissue necrosis, we demonstrated delayed release of cardiac troponin I (cTnI) that exceeded the 99th percentile for normal animals 60 min after reperfusion and

Suppression of Superoxide-Hydrogen Peroxide Production at Site IQ of Mitochondrial Complex I Attenuates Myocardial Stunning and Improves Postcardiac Arrest Outcomes

Critical Care Medicine, 2019
Supplemental Digital Content is available in the text. Objectives: Cardiogenic shock following cardiopulmonary resuscitation for sudden cardiac arrest is common, occurring even in the absence of acute coronary artery occlusion, and contributes to high ...

Assessment of Fluid Status in Dialysis: Clinical Importance and Diagnostic Tools [PDF]

Revista Portuguesa de Nefrologia e Hipertensão, 2022
Fluid status is crucial for dialysis patients. Volume overload is a major cardiovascular risk factor. Nevertheless, volume depletion is associated with myocardial stunning and cerebral ischaemia.

Translational studies to understand myocardial stunning in acute myocardial infarction [PDF]

Myocardial stunning is a reversible contractile dysfunction that persists despite the resolution of myocardial ischemia. It is commonly associated with acute myocardial infarction. However, myocardial stunning also occurs in other acute cardiomyopathies,

Tako-tsubo syndrome and hypovolemia

Monaldi Archives for Chest Disease, 2016
Tako-tsubo syndrome (TTS) is a rare disorder characterized by reversible apical left ventricular ballooning usually triggered by an emotional and/or physical stress and often mimicking an acute myocardial infarction.
