However it is becoming apparent that the same stem cells may both restore contractility (directly or indirectly) and improve the cardiac circulation [2].
If non-invasive techniques are inadequate (< 0,5 °C/hour), and moreover in case of cardiac arrest, femoral cardiopulmonary bypass is the best technique to assist the cardiac circulation and rewarm the patient.
Venous air embolism (VAE) during pars plana vitrectomy (PPV) can occur owing to improper positioning of the infusion cannula in the suprachoroidal space and may lead to sudden compromise of cardiac circulation and death.
The reasoning behind this suggestion is that, at temperatures at or below the optimum and probably because of a limitation on oxygen diffusion in skeletal muscle during exercise, venous oxygen does not fall below a threshold level during exercise, and so the heart receives just enough oxygen for its own muscular activity via the cardiac circulation (i.e. the venous return to the heart).
Larvae tolerated overnight incubation in the majority of the 3,840 compounds analyzed in the primary screen, however 67 compounds (1.75%) caused larval death or severely compromised cardiac circulation and were therefore deemed toxic.
An animal model mimicking human cardiac circulation may be of great help.
Analysis will use specialised cardiac CT circulation software with intraventricular tracings of end systolic and end diastolic timings.
A significant stenosis was defined as an area stenosis of >75% on DSCT using dedicated cardiac software (Circulation, Siemens, Forchheim, Germany).
The results of the present study reveal that ventilating an ECML with up to 300 ppm H2S in venoarterial cardiac bypass circulation does not reduce whole body CO2 production or O2 consumption in anesthetized sheep.
28 The following chronic conditions were listed: arthritis, edema, asthma, emphysema, blood pressure, cardiac or circulation problems, diabetes, stomach ulcer, digestive chronic conditions, liver disease, urinary problem, osteoporosis, anemia, thrombosis, stroke, Parkinson's disease, muscular dystrophy, thyroid problem, and others.
A comorbidity index was calculated, scoring one for each of the following problems the subject reported: hypertension, cardiac disease, circulation problems, stroke, diabetes, respiratory problems, pain in joints or bones, tumours or cancer, Parkinson's disease, genito-urinary problems and gastrointestinal problems.
