Transmural cellular damage and blood flow distribution in early ischemia in pig hearts.
Transmural histological changes were determined morphometrically in the left ventricular free wall of 20 pigs after ligation of distal left anterior descending coronary artery for 10, 20, 40, and 120 minutes. Hemodynamics were recorded and regional blood flow distribution was measured in the ischemic zone. Coronary occlusion produced regional transmural ischemia without producing significant sy...

15 صفحه اولImaging of ischemia and infarction in blood-perfused pig hearts using 87Rb MRI.
87Rb-MRI was used to measure Rb(+) uptake in blood-perfused pig hearts during complete occlusion (120 and 70 min) of the left anterior descending artery (LAD) and subsequent reperfusion (120 and 170 min). The Rb(+) uptake rate and maximal Rb image intensity during 120-min occlusion were significantly lower in the ischemic anterior left ventricular (LV) wall (0.35 +/- 0.14%/min and 26 +/- 4.7%) ...

متن کاملDistribution of pulmonary blood flow after myocardial ischemia and infarction.
Regional distribution of pulmonary blood flow and ventilation was determined with the 133xenon technic in the erect position at the bedside in 15 patients an average of 6 days after uncomplicated myocardial infarction (MI) and in five patients with severe angina in the same coronary care unit. Follow-up studies were repeated within 3 to 25 weeks on six of the patients with MI. There was marked ...
