Aim.To study the effect of ACE inhibitors (ACEI) in heart recipients on the prognosis and myocardial remodeling.Materials and methods.Three hundred and eighty-six patients who received orthotopic heart transplantation (HT) were consequently enrolled to the study from February 2009 to November 2016.Results.Thirty days after the HT, ACEIs were assigned to 141 recipients. Arterial hypertension was diagnosed in all cardiac recipients who received ACEI and among 48 patients (19.5%) from non-ACEI group. Patients receiving ACEI had significantly better event-free survival than control group (p = 0.045) during the follow-up for 1361,6 ± 36,9 days. Left ventricle (LV) end-diastolic dimension did not change over the time in both groups, whereas LV posterior wall thickness in non-ACEI group significantly increased from 1.35 ± 0.03 cm to 1,23 ± 0.05 cm (p < 0.05).Conclusion.Cardiac recipients who received ACE inhibitors had better survival and less transplant left ventricle progression, that could reflect beneficial effects of renin-aldosterone-angiotensin system inhibition after heart transplantation.

Aim.To estimate the frequency and expressiveness of atherosclerotic lesions of the transplant coronary arteries of the determined by an angiographic method.Materials and methods.Coronary angiography was executed to 518 recipients of heart aged from 10 till 72 years (average 56,92 ± 12,1) within the first week after transplantation of heart (a median 6; 3–42 days). Men – 466, women – 52. Initial status of recipients: UNOS 1A – 217 of people, UNOS 1B – 89 of people, UNOS 2 – 212 people. Included the following criteria of the donor in the analysis: sex, age, cause of brain death.Results.Angiographic signs of atherosclerotic lesions of coronary arteries are discovered in 166 cases, in 65 cases defined as significant stenosis which demanded performance of the percutaneous coronary intervention (PCI). In 352 cases symptoms of atherosclerosis are not revealed (group of comparison). At recipients in the status UNOS 1A and UNOS 1B discovered the transmission of atherosclerosis (TA) more often, than recipients in the status UNOS 2 (54% and 36%, respectively). Age of donors in group with transmission of atherosclerosis was 50,2 ± 0,7 years, and in group of comparison – 41 ± 0,6 years (r = 0,0005). Range of donors age in groups did not differ and made 18–66 years for group of comparison and 20–67 years for group with transmission of atherosclerosis, but in subgroup of PCI made 31–67 years. Gender influence on the frequency of transmission of coronary atherosclerosis it is not revealed. Acute violation of brain blood circulation as the cause of brain death was observed in 76% of cases at TA group and 61% in group of comparison.Conclusion.The age of the donor and acute violation of brain blood circulation are the factors associations with probability of transmission of coronary atherosclerosis, however it is important to consider the status of the recipient.

Aim. To assess the changes in hemocoagulation parameters according to the grade of renal dysfunction in elderly patients with cardiorenal syndrome types II and IV.Material and methods. In 56 patients of the elderly age group (mean age 78±10 y.o.), with coronary heart disease and chronic heart failure, the parameters of blood clotting were assessed and the relations with kidney dysfunction grade measured by the level of glomerular filtration rate (GFR). Patients were selected to 3 groups. In 47 (83,9%) there was decline of GFR <60 mL/min/1,73 m2, of those in 8 (17,3%) <30 mL/min/1,73 m2; in 9 GFR >60 mL/min/1,73 m2, with no signs of proteinuria (16,1%). All patients underwent coagulological assessment of the blood with measurement of the activated partial thromboplastin time, thrombin time and prothrombin time, international normalized ratio and fibrinogen concentration, as the complete blood count with platelet number, mean platelet volume, thrombocyte distribution width, and thrombocrit.Results. The number of platelets did differ significantly in groups 1 and 3 (p=0,040), as 2 and 3 (p=0,007). Thrombocrit values did differ significantly only in 2 and 3 (p=0,029). In the group 3 the rate of the mentioned values was below the respective reference values. Fibrinogen levels did differ significantly in groups 1 and 3 (p=0,042), and 2 and 3 (p=0,037). In the group 3 the parameter was higher than upper limit of reference range. Correlation found for GFR and fibrinogen level (r=-0,425; p=0,004), for GFR and platelet number (r=0,271; p=0,049). The platelet number correlated with creatinine level (ρ=-0,392; p=0,004). Creatinine level also correlated with fibrinogen level (ρ=0,375; p=0,012).Conclusion. In the elderly, with the decline of GFR there is decline of thrombocyte number and increase of fibrinogen concentration together with an increase of the severity of kidney dysfunction. The pathological changes that were found might probably serve as additional factor influencing the risk of adverse events related to disorder of blood clotting. The importance of the revealed relations, as the aimfulness for clinical application, should be evaluated in controlled studies.
