[State of the blood platelet link of hemostasis and microcirculation in patients with ischemic heart disease during plasmapheresis treatment].

The paper provides the results of studies into plasmapheresis-induced changes in the thrombocytic link of hemostasis and microcirculation in 40 patients with coronary heart disease (CHD). Repeated sessions of plasmapheresis (P) were found to produce an inhibitory effect on platelet aggregation and to improve microcirculation in CHD patients with signs of increased platelet functional activity. In CHD patients with low platelet functional activity, the first P session was demonstrated to cause an increase in platelet functional activity whereas the subsequent sessions inhibited platelet aggregation. No significant microcirculatory improvement was seen in this group of patients. Heparin and rheopolyglucin given to control patients exerted no substantial effect on the thrombocytic link of hemostasis and microcirculation.

[Contrast echocardiography using hydrogen peroxide].

The practicability of using hydrogen peroxide solutions for contrast echocardiography was examined. The administration of 1-3 ml of 0.2% solution mixed with a drop of the patient's blood, into the cubital or catheterized subclavian vein produced intensive and lasting (up to 2 min) contrast of the right cavities of the heart. Cubital injection of the solution was associated with a more lasting effect, as compared to the subclavian administration. The causes of this difference are yet to be investigated. The contrasting effect was fairly persistent and marked even when concentrations of the hydrogen peroxide solutions were reduced to 0.15 or 0.1%. The rate of administration was not more than 1 ml/s and had no negative effect on the quality of the contrast. No side effects associated with repeated administration of 1-3 ml hydrogen peroxide solution in the above-mentioned concentrations were noted in either of the 20 patients thus examined.
