    Soon after haemodialysis was introduced into clinical practice, a high risk of cardiac death was noted in end-stage renal disease. However, only in the last decade has it become clear that any renal injury, acute or chronic, is associated with high overall and cardiovascular lethality. The need for early recognition of kidney damage in cardiovascular pathology to assess risk and develop tactics for patient management contributed to the emergence of the concept of the “cardiorenal syndrome” (CRS). CRS is a pathophysiological disorder of the heart and kidneys in which acute or chronic dysfunction of one of these organs leads to acute or chronic dysfunction of the other. The beneficial effect of ultrafiltration as a component of renal replacement therapy (RRT) is due to the elimination of hyperhydration, which ultimately affects the improvement in cardiac contractile function. This review considers the theoretical background, current status of CRS, and future potential of RRT, focusing on the benefits of ultrafiltration as a therapeutic option.

    Oxidative stress, depression, and risk of recurrence of stable coronary heart disease
    (2021) Ivascenko, Tarass; Voicehovskis, Vladimirs V.; Voicehovska, Julija G.; Skesters, Andrejs; Apsite, Ketija; Grigorjeva, Julija; Kivite-Urtane, Anda; Pahomova, Natalija; Kalejs, Oskars; Rīga Stradiņš University
    Aim: The aim of the study was to investigate the relationships between a level of oxidative stress (OS), depression (D) and risk of recurrence of stable coronary heart disease (SCHD). Methods: A retrospective study was conducted on 174 participants, at the age 45+ years: 86 in-patients of the cardiology department with a recurrent SCHD and 88 in-patients of the cardiology department with primary SCHD. The severity of depressive symptoms was assessed using the long 30-item form of Geriatric Depression Scale (GDS), valid Latvian version of GDS-LAT. The blood samples were taken from each patient to measure oxidative stress parameters malondialdehyde (MDA) and glutathione peroxidase (GPx). Results: 83.9% of the sample had high level of MDA. In 72.4% of the sample the GPx level was normal, in 17.8% it was high and in 9.8% low. Slightly more than a half of the patients were experiencing depression (44.3% – mild D and 6.9% – severe D). GPx was found statistically differing between primary and recurrent SCHD (p = 0,003). Patients with both D and high GPx had 10.6 times higher chances of recurrent SHCD compared to those without D and normal GPx (p = patients with present D were experiencing both – high levels of MDA and GPx – more often than responders with no D, but this wasn’t statistically significant [p = 0.51]). Conclusion: In the present study it was found that level of antioxidant (AO) enzyme GPx was significantly higher in depressed patients with recurrent SCHD compared to patients without D and to patients with primary SCHD and patients with both D and high GPx had higher chances of recurrent SCHD compared to those without D and normal GPx. It could be supposed that GPx is a more significant marker of risk of D and recurrence of SCHD. The high level of MDA in most of both (primary and recurrent SCHD) groups patients could evidence that increased OS is a risk factor for CHD in general. Monitoring OS biomarkers seems to be important in the management of SCHD comorbidity with D. Further studies are warranted to confirm these findings.
