title: [Effect of the ion composition of the calcium-free medium and cardiomyocyte damage during "calcium paradox" in rats].
abstract: The findings reveal that the degree of myocardial damage in the "calcium paradox" does not depend on the contracture strength, that the contracture attenuation due to a decreased concentration in the Ca-free medium is not equal to the cardiocytes protection as compared with other means. Mg2+ and the studied means of myocardial protection seem to play a major role in assessment of the "calcium paradox" development and explain the difference in results of the hyposodium medium effects in the "calcium paradox".
