title: [Integrated assessment of serum homeostasis shifts in experimental myocardial infarction].
abstract: Dynamic changes in serum homeostasis of rats with experimental myocardial infarction evolution using the method of laser correlation spectroscopy were studied. The presence of necrotic myocardial damage was confirmed by electrocardiographic, histological and biochemical methods. Increased contribution of small particles in the acute period of myocardial infarction was detected, which indicates products of catabolism accumulation in serum and changing the level of some proteins. Comparison of subfractional content of sera from rats with varying degrees of extension of myocardial necrosis through the ventricular wall revealed the predominance of particles of low molecular size (up to 10 nm) in animals with transmural infarction and middle-size fraction (50-120 nm) in animals with non-transmural infarction. These results are consistent with the clinical data obtained by this method in patients with Q-wave and non-Q-wave myocardial infarction.
