In a group of 25 anesthetized mice, cardiac output, cardiac index, and stroke volume were determined. Five mice of this group were studied a second time to assess the reproducibility of PET ...

The cardiac output rose during exercise almost exclusively as a result of an increase in the heart rate, with the stroke volume remaining practically constant. Despite similar increase in cardiac ...

Cardiac output values obtained with impedance cardiography were significantly correlated with those measured by the indirect Fick method, although there was a wide scatter with over 73% of the ...

For surgeons already split on their preference of inhaled pulmonary vasodilator to prevent postoperative right ventricular ...

Abstract: The determination of cardiac output and central blood volume is of considerable importance, not only in cardiac research but in the diagnosis and treatment of heart disease. At present, the ...

of six patients did inhalation of 100% oxygen lower cardiac output significantly. In four patients, studied in both the supine and sitting posture, orthostatic stress was consistently accompanied by a ...

One area of growing interest in stroke research is the role of cardiac biomarkers, particularly cardiac troponins, in predicting outcomes for patients with AIS. Cardiac troponins are proteins ...

It is the measured, dynamic, beat-to-beat changes in impedance that are processed and applied to an algorithm to calculate stroke volume and cardiac output. Direct and derived variables measured ...

The following is a summary of “Cardiovascular effects of lactate in healthy adults,” published in the January 2025 issue of ...

Figure 2: a, Baseline pressure–volume loops from control and mutant mice. The fall of in vivo cardiac output in hearts of older mice supports earlier data obtained in excised ejecting hearts 7 ...

Nov. 13, 2024 — Researchers have identified a new target to treat atherosclerosis, a condition where plaque clogs arteries and causes major cardiac issues, including stroke and heart ...

Aims Exercise testing remains underused in patients with aortic stenosis (AS), partly due to concerns about an ...
