The effect of standard- and high-dose epinephrine on coronary perfusion pressure during prolonged cardiopulmonary resuscitation.
In the MR heart, the LVAD with LAAO and LVAO cannulation sites succeeded in restoring cardiac functions, which reduced ATP consumption, increased the aortic pressure for coronary perfusion, and provided sufficient cardiac output to the body.
Effect of graded reductions in regional coronary perfusion and total cardiac function.
The Ang II infusion induced increases in coronary perfusion pressure in a concentration-dependent fashion in all experimental groups (Figure 3(a)).
In brief, the rat hearts were isolated and retrogradely perfused with Krebs-Henseleit (K-H) buffer equilibrated with 95% [O.sub.2] and 5% [CO.sub.2] (pH 7.4) in Langendorff perfusion system (ADInstruments, Australia) at a constant coronary perfusion pressure of 65 [+ or -] 1 mm Hg at 37 [degrees]C for 20-30 min (stabilization), then perfused at 20 [+ or -] 1 mm Hg for 40 min to produce a global low flow ischemia, and finally reperfused at 65 [+ or -] 1 mm Hg for 10 min.
Furthermore, the effect of rat calcitonin on coronary perfusion pressure and heart rate has not been studied and little is known on the effect of rat calcitonin on contractile force.
Decreased coronary perfusion pressure, anaemia, hypoxaemia and tachyarrhythmias are typical causes.
Therefore, coronary perfusion occurs during diastole.
Buis goes on to state, "Chase Medical is deeply involved in, and committed to further innovative and unique product development projects which address the remaining challenges of beating heart surgery, including hemodynamic stability during cardiac manipulation, and optimal coronary perfusion during the surgical procedure.
To evaluate coronary perfusion pressure (CPP) and endothelium-dependent vasodilation, animals were anesthetized with chloral hydrate (40 mg/kg, ip).
* Hypotension should be rapidly treated in order to restore coronary perfusion pressure (CPP).
In the context of full-thickness myocardial infarction, prompt restoration of coronary perfusion has been shown to reduce morbidity and mortality significantly, with percutaneous coronary intervention being the more effective revascularisation method [5, 6].
