Regional left ventricular epicardial deformation in the passive dog heart.
Epicardial wall motion was measured on the left ventricular free wall in six isolated potassium-arrested dog hearts using a biplane video technique. Significant regional variations in epicardial deformations were recorded during static ventricular filling. Epicardial stretches varied linearly with cavity volume, sometimes exceeding 20% at physiological left ventricular end-diastolic pressures. ...
متن کاملThe effect of asafoetida essential oil on myocardial ischemic-reperfusion injury in isolated rat hearts
Objective: Previous studies reported that asafetida from Ferula assa-foetida Linn. species and its essential oil (AEO) have antioxidant effects. In the present study, the effect of AEO was evaluated on ischemic-reperfusion injury in isolated rat hearts. Materials and Methods: Forty-eight male Wistar rats were divided into 6 groups: 1) control group, 2) vehicle group, 3-5) AEO groups and, 6) car...
متن کاملCoronary hypertension and diastolic compliance in isolated rabbit hearts.
Acute pulmonary edema during hypertensive crisis has been attributed to acute left ventricular systolic failure secondary to increased afterload. We tested the hypothesis that the increase in coronary artery perfusion pressure associated with systemic hypertension could also contribute to increased left ventricular filling pressures by acutely increasing coronary intravascular volume and decrea...
متن کاملPacing the Heart: Is It a Must in Studying Myocardial Contractile Function in Isolated Hearts Perfused Using the Langendorff System
Background: Myocardial contractile function has been studied extensively in isolated hearts using the Langendorff System. The effects of changing the heart rate on myocardial contractility have not been described. The aim of the present study was to examine the effects of changing the heart rate on studying myocardial contractility in isolated heart models using the Langendorff System, and to d...
متن کاملNorepinephrine release and left ventricular pressure in the isolated heart.
In an isolated dog heart, perfused with blood from an anesthetized donor, left ventricular performance was observed during periods in which the left ventricle either contracted isovolumically or was allowed to eject saline. Heart rate and left ventricular end-diastolic pressure were comparable in both. Ventricular performance, as judged by peak systolic ventricular pressure, declined relatively...
