[Emergency angioplasty of the coronary arteries in the treatment of acute myocardial infarction]. / Ekstrennaia angioplastika venechnykh arterii v lechenii ostrogo infarkta miokarda.

The comparative assessment of lethality, incidence of development of repeated myocardial infarction and complications, indices which evidence in favour of improvement of the left ventricular function in 36 patients with acute myocardial infarction (group 1) who underwent superselective intracoronary thrombolysis alone, and in 10 patients (group 2) who underwent emergency coronary angioplasty after successful intracoronary thrombolysis is presented. The best immediate and long-term results were noted in group 2 patients.

[Roentgenoendovascular dilatation of the renal arteries in the treatment of vasorenal hypertension]. / Rentgenoéndovaskuliarnaia dilatatsiia pochechnykh arterii v lechenii vazorenal'noi gipertenzii.

The possibilities of the use of roentgenoendovascular dilatation of the renal artery were studied in 57 patients with stenosis of the renal artery and vasorenal hypertension. The authors managed to perform the manipulation in 48 patients. Occlusion of the renal artery, pronounced atherosclerosis of the iliac and axillary arteries, coarctation of the aorta were the causes of failure. In 52.6% of the patients, the "residue" of stenosis was less than 30% of the normal arterial lumen, in 31.6%--30-50%, in the remaining patients, the dilatation has failed. Stable normotension was achieved in 39.5%, the state improved in 50% of the patients. The absence of hypotensive effect for the first 6 mos after the operation was caused by recurrency of the dilated artery stenosis, which resulted from the improper choice of a balloon catheter. The diameter of such a catheter should be 100-110% of a width of the renal arterial lumen proximally to stenosis. The later recurrency of hypertension was caused by the development of the stenosis of the artery of the contralateral kidney.

[Incidence of decreased insulin sensitivity in obese patients]. / Issledovanie chastoty snizheniia chuvstvitel'nosti k insulinu u bol'nykh ozhireniem.

A method has been presented for the detection of organism sensitivity to insulin, involving simultaneous administration of insulin (intravenously) and the solution of partially hydrolized starch (orally), followed by the determination of the blood sugar level after 1 and 2 hours. By means of this method sensitivity to insulin was established in 55 patients with obesity and 16 healthy humans. It was found that sensitivity to insulin among patients with obesity of the I-III stages is lowered in 33% of cases and in subjects with the IV stage of the disease in 62%. The results of the determination of sensitivity to exogenous insulin correlate with IRI level in these patients.
