Alterations of Myocardial Function during Early Stages of Mild Experimental Ischemia in Dogs Determined by Left Ventricular Pressure-Wall Thickness Loop

Alterations of Myocardial Function during Early Stages of Mild Experimental Ischemia in Dogs Determined by Left Ventricular Pressure-Wall Thickness Loop

Alterations of regional left ventricular myocardial function immediately after coronary artery branch ligation as related to the total left ventricular function were determined by utilizing left ventricular pressurewall thickness loop in 6 anesthetized open-chest dogs. End-diastolic wall thickness w...

Zusammenfassung:Alterations of regional left ventricular myocardial function immediately after coronary artery branch ligation as related to the total left ventricular function were determined by utilizing left ventricular pressurewall thickness loop in 6 anesthetized open-chest dogs. End-diastolic wall thickness was decreased immediately from 11.54±0.50mm (standard error of the mean) of control to 10.99±0.50mm in 5 to 10min after ligation (p
