[Changes in the size of the damage to the normal nonischemic myocardium adjacent to the risk area for infarct development in permanent and transient coronary occlusal ischemia].

The results of morphometric analysis of the myocardial infarction area show that the involvement of normal myocardium, ajacent to the risk zone of infarction, into the damaging process is insignificant or absent both in continual and transitory ischemia.
