[Quantitative ultrastructural criteria of myocardial damage in postischemic reperfusion].
Swollen clarified mitochondria were found during postischemic reperfusion in cardiomyocytes with and without signs of myofibril relaxation. The values of morphometric parameters of mitochondria were similar in both groups of cells studied. Mean indexes characterizing the condition of cardiomyocyte mitochondria may serve as quantitative criteria of the severity of myocardial damage: surface to volume, ratio, visual index of mitochondrial condition and relative volume density, i.e. volume density with respect to control cell volume.
