Effects of Myocardial Ischemia on Regional Myocardial Function in the Experimental Animal

  • David A. Cox

Abstract

The most important aspect of myocardial ischemia is its effect on myocardial mechanical function. For centuries there has been an interest in the effects of coronary artery occlusion on the heart [1]. By the late nineteenth century, it was appreciated that coronary artery occlusion induced a fall in arterial pressure [2], but quantitative measurements of the effects of ischemia on contraction were first described in 1935 by Tennant and Wiggers [3]. One of the goals of this chapter is to review the merits and limitations of various experimental techniques for measurement of regional myocardial function in ischemia. Another is to discuss the effects of ischemia on myocardial contraction immediately after the onset of ischemia, during the steady-state and with chronic ischemia and infarction. Finally, we will examine the reversibility of derangements in myocardial function with reperfusion after brief coronary artery occlusions insufficient to induce infarction and after occlusions of up to several hours duration.
