[A comparative analysis of the inclination angle of rigid and soft IOLs with intracapsular fixation]. / Sravnitel'nyi analiz naklona zhestkikh i miagkikh intraokuliarnykh linz s vnutrikapsul'noi fiksatsiei.

Eighty-four eye were examined in 67 patients after phacoemulsification with intracapsular IOL implantation. The patients were shared, with respect to IOL rigidity, between 2 groups: group 1--rigid PMMA lenses and group 2--soft hydrogel and acryl lenses. The inclination angle was evaluated for different lens types by using an elaborated mathematical formula. The lenses had capsular fixation in all cases. The deviation angle ranged from 0.58 to 1.22 degrees. The difference between the inclination angle and ocular visual axis for rigid and soft lenses was statistically reliable (p < 0.05). The inclination angle of the optic axis in case of soft lenses versus rigid lenses was to a greater extent pronounced after 2 months of observation. However, the conclusion is not final due to continuous fibrosis of the capsular sac, which affects dynamically the IOL positioning. Therefore, similar studies will be made after 12-14 months to enable final conclusions.

[Hemodynamic and oxygen supply during exercise in patients with cardiac pacing during treatment of heart failure]. / Sostoianie gemodinamicheskogo i kislorodnogo obespechenia fizicheskoi nagruzki u bol'nykh s élektrokardioctimuliatsiei na fone lechenia serdechnoi nedostatochnosti.

Invasive and non-invasive tools were used to examine the specific features of exercise hemodynamic and oxygen supply in time in 25 patients with heart failure who underwent permanent pacing during a long-term glycoside and vasodilator therapy. It is shown that treatment with glycosides and vasodilators should be used in patients having severe myocardial systolic dysfunction and undergoing pacing. In the absence of this abnormality, it is advisable to use peripheral vasodilators (corvaton or sydnopharm) and diuretics for a long time.

[Hemodynamic support of physical loads in patients with ischemic heart disease and a permanent artificial pacemaker]. / Gemodinamicheskoe obespechenie fizicheskoi nagruzki u bol'nykh ishemicheskoi bolezn'iu serdtsa s postoiannym iskusstvennym voditelem ritma.

A study, using noninvasive monitoring during bicycle ergometry, was carried out to assess hemodynamic support of physical stress in coronary patients with implanted pacemaker (IPM). Heart contractility of IPM-carrying coronary patients was reduced, with capacity for compensation diminished even at rest, while exercise contributed to further deterioration of those. Adequate hemodynamic support of stress was only observed in patients belonging to the second functional class.
