Representatives from cardiology (interventional, advanced heart failure, noninvasive), emergency medicine, critical care, and cardiac nursing all collaborated to develop the proposed schema. (getinge.com)

Hearts were freeze-clamped at different time points during the protocol. (portlandpress.com)
Some of the hearts were freeze-clamped immediately prior to the 40 min ischemic period to determine pre-ischemic glycogen content. (utmb.edu)

They can occur any time during the neonatal period. (childneurologyfoundation.org)
however, elevation of troponin levels can occur in myriad conditions other than ischemic damage. (medscape.com)

Our results demonstrated that these immature cells have a natural capacity to differentiate into endothelial cells in infarcted hearts. (elifesciences.org)

If ischemia is detected, medication should be titrated to specific endpoints of heart rate and blood pressure or until the ischemia resolves. (medscape.com)

This was accompanied by higher numbers of Ly6C hi monocytes in peripheral blood, as well as higher expression of monocyte chemoattractant protein-1 and adhesion molecules in the hearts of MI-operated Hmox1 −/− mice. (springer.com)

Anesthetized pigs underwent 90 min of regional LV ischemia and 90 min of reperfusion. (diabetesjournals.org)

reported that chronic administration of empagliflozin enhanced ATP production in the heart of db/db mice, although they argued that this was due to an increase in glucose and fatty acid oxidation rather than the utilization of ketone bodies 8 . (nature.com)

Persistent myocardial ischemia and hypoxia will cause malignant cardiac remodeling and subsequent heart failure. (hindawi.com)

We have developed the first system, to our knowledge, that simultaneously measures 31P nuclear magnetic resonance (NMR) and optical action potentials (APs) in order to determine the dynamic relationship between certain metabolic markers and AP morphology during acute ischemia in rabbit hearts. (unc.edu)

In addition, several studies have demonstrated the beneficial effects of empagliflozin on myocardial infarction (MI) in diabetic animal models 10 , 11 , prompting us to investigate the real-time ATP change in cardiac energy production in an ischemic-reperfusion model of MI. (nature.com)
