by using excised perfused heart preparations , we investigated the regional myocardial functions in the presence of a flow-limiting coronary stenosis of the left circumflex coronary artery ( lcx ) ( approximately low reduction of pre-ischemic control ) , as well as global cardiac functions during afterload reducing , while keeping left ventricular end-diastolic pressure ( lvedp ) and heart rate constant .
