Sentence examples for cardiac stunning from inspiring English sources

IRI produces myocardial injury during MI and cardiac stunning after CPB via overlapping cellular mechanisms [ 45, 47].

Additionally, frequently occurring cardiac stunning - a transient, reversible, postoperative contractility impairment - may require inotropic support to prevent tissue hypoperfusion and organ dysfunction.

Indications for start of the protocol were: hypotension (in spite of fluids), pulmonary edema or cardiac stunning, daily fluid balance ≤-1 l, cerebral ischemia (DCI) with progressive symptoms.

The distinction between cardiogenic shock and transient postoperative cardiac stunning - diagnosed in 45% of elective patients - is important as they are associated with different hospital paths and outcomes.

Microvascular dysfunction, adrenal insufficiency, mitochondrial dysfunction, cardiac stunning from direct-current countershocks, and cardiovascular effects of iatrogenic interventions including TH further contribute to PAMD and shock after ROSC [ 44].

With regard to treatment-related factors, several studies have shown disturbances in regional wall contractility during the dialysis procedure, attributed to cardiac stunning (impaired but reversible myocardial contractility due to ischaemia) [ 40], which were not present before dialysis [ 41, 42].

These nucleosides leak out of the cell (and may have vasodilator effects through purinergic receptors) and lead to a gradual depletion of adenine nucleotide which may contribute to the reduced cardiac performance (stunning) seen on reperfusion.

Clinically, reperfusion injury may be seen in four different types of cardiac dysfunction: myocardial stunning - that is persistent mechanical dysfunction despite restored blood flow which is usually reversible within weeks; the no-reflow phenomenon after opening of an infarcted coronary artery; reperfusion arrhythmia; and lethal, irreversible injury of the myocardium.

Levosimendan improves cardiac performance in myocardial stunning after percutaneous intervention [ 40].

At the cardiomyocyte level, intracellular calcium overload occurs during post-ischemic reperfusion, and could cause cardiac arrhythmias or myocardial stunning.

The molecular mechanisms of myocardial stunning after cardiac arrest remain unknown, but loss of excitation contraction coupling is believed to result from ROS injury and calcium-mediated proteolysis.
