[Novel assessment of intracellular calcium transient decay in cardiac muscle by curve-fitting with half-logistic function].

open access: closedMasui. The Japanese journal of anesthesiology, 2008
A decrease in intracellular calcium (Ca2+) concentration in the cardiac muscle is one of the important factors to induce myocardial relaxation. A mono-exponential (m-E) function has been used for assessing myocardial relaxation curve of isometric tension and intracellular calcium transient (CaT) decay, and the m-E time constants for the relaxation ...

Cardiac Output Response to Norepinephrine in Postoperative Cardiac Surgery Patients

Critical Care Medicine, 2013
We studied the variable effects of norepinephrine infusion on cardiac output in postoperative cardiac surgical patients in whom norepinephrine increased mean arterial pressure. We hypothesized that the directional change in cardiac output would be determined by baseline cardiac function, as quantified by stroke volume variation, and the subsequent ...

Usefulness of right ventricular function with time intensity curve of rest perfusion cardiac MRI

2018
Aims and objectives: Background Recently, right ventricular ejection fraction (RV-EF) has been shown to be an important prognostic factor of left heart failure, in addition to left ventricle ejection fraction (LV-EF), and is used to conventionally measure cardiac...
