Aim. To assess the influence of hyperuricemia on the risk of contrast-induced acute kidney injury (CI-AKI) in patients with stable coronary artery disease (CAD) and arterial hypertension. Materials and methods. Patients receiving optimal medical therapy and with indications for coronary angiography and possible coronary angioplasty, with stable CAD and arterial hypertension were included in the study. We conducted an observational open prospective cohort study, that was registered in clinicaltrials.gov with ID NCT04014153. Results. We included 1023 patients with chronic CAD. 863 had arterial hypertension. Hyperuricemia was diagnosed in 31 patients, 832 had normal levels of uric acid on admission. Contrast-induced acute kidney injury developed in 2 (6.5%) patients suffering from hyperuricemia. In patients with stable CAD, AH and no hyperuricemia the rate of CI-AKI was 107 (12.9%) patients. The difference between groups was not statistically significant (95% CI -0.056–0.183, р=0.292). We built a multiple linear regression model that included age, weight, female gender, heart failure, diabetes mellitus, kidney diseases in past medical history, protei-nuria, anemia, baseline glomerular filtration rate, contrast volume and difference between baseline creatinine and creatinine after contrast administration. No risk factor showed any statistical significance in the model. Conclusion. Contrast-induced acute kidney injury developed in 2 (6.5%) patients suffering from hyperuricemia. The rate of CI-AKI in patients without hyperuricemia was twice higher but the results were not statistically significant. Among the risk factors included in the multiple linear regression model none was statistically significant.

Relevance.The combination of stable coronary artery disease (CAD) and arterial hypertension (AH) is one of the most common seen by cardiologists. The administration of contrast media might increase the risk of development of acute kidney injury, especially in patients with comorbidities. The influence of iodine contrast media administration on the risk of development of contrast-associated acute kidney injury (CA-AKI) in patients with stable CAD and AH was studied in our work. Materials and methods.863 patients with stable CAD and AH and indications for interventions requiring intraarterial administration of contrast media were included in the prospective open observational cohort study (ClinicalTrials.gov ID NCT04014153). CA-AKI was defined according to KDIGO criteria as the elevation of serum creatinine 25% and more above baseline or 0.5 mg/dl (44 mkmol/l) and more in 48 hours after intraarterial administration of contrast media. The primary endpoint was the development of CA-AKI. Results.Diabetes mellitus, obesity and hyperuricemia were not statistically significant risk factors of CA-AKI development according to the contingency tables analyses, unlike proteinuria. A logistic regression model was built (area under the curve 0.7638,p0.0001, 95% confidence interval 0.7130.815) and included the following risk factors: age, weight, body mass index, female gender, heart failure, proteinuria, AH, anemia, baseline creatinine. Proteinuria, baseline creatinine and contrast volume were statistically significant ones. Conclusion.The rate of CA-AKI was 12.6%. Proteinuria, baseline creatinine and contrast volume were statistically significant risk factors of CA-AKI in logistic regression model.

Abstract Background and Aims Contrast-induced acute kidney injury (CI-AKI) remains one of the major obstacles to perform percutaneous coronary interventions (PCI), especially in older patients and in patients with comorbidities. The number of cases of stable coronary artery disease (CAD) requiring such kind of interventions, in spite of optimal medical treatment received, remains high. Diabetes, hyperuricemia and other components of metabolic syndrome, as well as heart failure, are well known risk factors predisposing to the development of CI-AKI after contrast exposure. Anaemia is diagnosed in a number of patients without underlying chronic kidney disease (CKD), when they seek for medical help due to CAD. The aim of our study was to assess the prevalence of CI-AKI (primary outcome) and the prognostic significance of anaemia as a its possible risk factor (secondary outcome) in different groups of patients with stable CAD requiring PCI using the contrast media. Method We conducted a single-centre prospective observational cohort study. 561 patients aged 18-89 with stable CAD undergoing PCI were enrolled from June 2012 until October 2013. The CI-AKI was defined as a rise in serum creatinine of ≥0,5 mg/dl (≥44μmol/l) or a 25% increase from baseline value, assessed at 48-72 hours after PCI. Anaemia was defined according to the WHO definition – haemoglobin level <12,0 g/dl in women and <13,0 g/dl in men. The contrast media used was either iodixanol (iso-osmolar contrast) or iopromide (low-osmolar contrast), which are both known to cause less adverse events than high-osmolar types of contrast. Nephrotoxic drugs were stopped 48 hours before PCI. The 5-year prognosis including all-cause and cardiovascular mortality, myocardial infarction, stroke, gastrointestinal bleeding, decompensation of chronic heart failure, repeat revascularizations (PCI and coronary artery bypass grafting), end-stage renal disease (ESRD) development, was assessed via phone calls and appointments according to the clinical situation and severity of the condition. Results The prevalence of CI-AKI in this group of patients was 104 cases (18,5%) (primary outcome). The number of patients with anaemia was higher in the group of patients who developed CI-AKI after PCI (6% [7/104] vs 4,4% [20/457]). The female patients with anaemia were more likely to develop CI-AKI (71% [5/7] vs 35% [7/20]). The number of patients who suffered from MI having anaemia at the inclusion date was 2 (28,6%) vs 6 (30%) in patients with and without CI-AKI respectively. Acute heart failure decompensation in patients with anaemia was significantly higher in patients with CI-AKI (43% [3/7] vs 10% [2/20]). This fact needs further evaluation in larger studies but anaemia may be one of the prognostic factors, worsening the kidney damage and leading to worse cardiorenal outcomes. Conclusion Patients with stable CAD suffering from anaemia are more likely to develop CI-AKI even without underlying CKD or ESRD. Female patients with anaemia and stable CAD have higher risk of development of CI-AKI. The combination of CI-AKI and anaemia may lead to a higher 5-year risk of acute heart failure decompensation.

Aim. To assess the prevalence of contrast-induced acute kidney injury (CI-AKI) in patients with stable coronary artery disease (CAD) and hyperuricemia. Materials and methods. Patients with stable CAD receiving optimal medical therapy and with indications to coronary angiography and possible coronary angioplasty were included in an observational open prospective cohort study. The protocol of the study was registered in clinicaltrials.gov with ID NCT04014153. We conducted a sub-analysis of the group of patients with hyperuricemia (uric acid level >7 mg/dl). Results. We included 1023 patients with stable CAD. 32 patients suffered from hyperuricemia. The rate of CI-AKI in this group was 6.25% (2 patients), that was lower than in patients with normal levels of uric acid (13.1%). The difference was not statistically significant probably due to the small number of patients with hyperuricemia. The patients with hyperuricemia had proteinuria 3 times more frequently, than patients without, the rate of diabetes mellitus was 7% higher as well as anemia by 4.5% but didn’t reach statistical significance. Conclusion. The rate of CI-AKI in patients with hyperuricemia was twice lower than in patients with normal levels of uric acid. More research needs to be conducted in patients with metabolic syndrome in larger groups.

Aim.The aim of our study was to assess the prevalence of contrast-induced acute kidney injury (CI-AKI) in patients with stable coronary artery disease (CAD) receiving optimal medical treatment with indications to coronary angiography and intraarterial administration of contrast agents. Materials and methods.1023 patients with stable CAD were included in the open prospective observational cohort study. The CI-AKI was defined as a rise in serum creatinine 25% from baseline. The mean age of the study group was 61.710.1 years; 72.4% were males and 84.4% had arterial hypertension. A multiple logistic regression model of prediction of CI-AKI was created. Results.CI-AKI developed in 132 (12.9%) of the patients. The multiple logistic regression model included gender, BMI, weight, age, heart failure, diabetes mellitus, arterial hypertension, anemia, hyperuricemia, proteinuria and baseline serum creatinine. Area under the curve for the model was 0.749 (95% confidence interval 0.7030,795;p0.0001). When trying to build a prognostic model, including baseline GFR and contrast volume, the model lost significance and the AUC diminished. Conclusion.The CI-AKI remains quite a common kidney injury developing in patients with stable CAD undergoing percutaneous interventions. Several risk factors need to be assessed very carefully before any intervention requiring intraarterial contrast media administration especially in patients with comorbidities.

Background. Arterial hypertension (HT) is a serious and prevalent epidemiological factor in the development of coronary artery disease (CAD). Metalloproteinases (MMPs), especially MMP-2 and MMP-9, and their natural endogenous tissue inhibitors (TIMPs) are involved in the pathogenesis of HT and its complications. MMPs are also involved in the development of diabetes (DM), a risk factor for CAD. The aim of the study was to explore the influence of CAD, HT, and DM on changes in plasma levels of MMP-2 and MMP-9 and their inhibitor TIMP-4. Methods and Results. The study involved 70 patients with stable CAD admitted for coronary angiography and 15 healthy subjects. Whole blood samples were collected prior to angiography. MMP-2, MMP-9, and TIMP-4 levels in plasma were estimated using ELISA tests. CAD patients showed a significantly increased level of TIMP-4 and decreased level of MMP-2 in comparison to healthy controls (p=0.011 and p=0.037, respectively). Concentration of MMP-2, MMP-9, and TIMP-4 did not differ in the group with and without hypertension. Patients with DM presented higher MMP-2 level than patients without DM (p<0.001). Multiple regression analysis of the influence of independent variables such as CAD stage, DM, and HT on MMP-2, MMP-9, and TIMP-4 showed that only DM was independently associated with a higher level of MMP-2 (β = 0.42, R2 = 0.17, p<0.001). Conclusion. Data showed that patients with CAD presented higher TIMP-4 and lower MMP-2 concentration regardless of HT and DM. HT had no effect on MMP-2, MMP-9, and TIMP-4 levels in serum. DM was independently associated with higher MMP-2 concentration; however, co-occurrence of CAD and DM was associated with the balance in the MMP-2 level. Concentration of MMP-9 did not change significantly in any of the analysed groups.

AbstractThe role of ST2 in stable coronary artery disease (CAD) has not yet been well defined. This study was performed to investigate baseline serum soluble ST2 (sST2) level can predict clinical outcomes in patients with stable CAD. A total of 388 consecutive patients with suspected CAD (65 years and 63.7% male) in stable condition referred for elective invasive coronary angiography (ICA) was prospectively recruited. Major adverse cardiovascular event (MACE), including cardiac death, non-fatal myocardial infarction, coronary revascularization (90 days after ICA), and ischemic stroke during clinical follow-up was assessed. Most of the patients (88.0%) had significant CAD (stenosis ≥ 50%). During median follow-up of 834 days, there was 29 case of MACE (7.5%). The serum sST2 level was significantly higher in patients with MACE than those without (47.3 versus 30.6 ng/ml, P < 0.001). In multiple Cox regression model, higher sST2 level (≥ 26.8 ng/ml) was an independent predictor of MACE even after controlling potential confounders (hazard ratio, 13.7; 95% confidence interval 1.80–104.60; P = 0.011). The elevated level of baseline sST2 is associated with an increased risk of adverse clinical events in stable CAD patients. Studies with larger sample size are needed to confirm our findings.

Aim.The aim of our study was to assess the role of anemia as a risk factor of contrast-associated acute kidney injury (CA-AKI) in patients with stable coronary artery disease. Materials and methods.1023 patients with chronic coronary artery disease were enrolled in a prospective, open, cohort study (ClinicalTrials.gov ID NCT04014153). 83 patients had anemia. CA-AKI was defined as an increase of 25% or more, or an absolute increase of 0.5 mg/dl or more in serum creatinine from baseline value, assessed at 48 hours following the administration of the contrast. The primary endpoint of the study was the development of CA-AKI according to KDIGO criteria. Results.CA-AKI developed in 12 (14.5%) patients with anemia according to the relative increase of the level of serum creatinine (25% and more from the baseline). With using the absolute increase of the level of serum creatinine the prevalence of CA-AKI was 2 (2.4%) patients. Patients with anemia had higher rate of CA-AKI than the overall population of the study (14.4% versus 12.7%). Although our results were not statistically significant (р=0.61, odds ratio 1.19, 95% confidence interval 0.632.24). Conclusion.The prevalence of CA-AKI was higher in the group of patients with anemia, but didnt meet statistical significance and needs further evaluation in larger studies.

The study aimed to analyze kidney function for patients with complicated forms of coronary artery disease (CAD) in the perioperative period. Methods. It was a retrospective analysis of 110 high-risk patients with complicated forms of CAD, who were operated on and discharged from the National M. Amosov Institute for the period from 2009 till 2019 years. Kidney function was evaluated by glomerular filtration rate (GFR), calculated online with СKD-EPI formula. Results. Among the included patients there were 86 (78.1%) patients with metabolic syndrome, 81 (73.59%) patients with disorders of glucose metabolism, 82 (74.5%) subjects with chronic obstructive pulmonary disease and 38 (34.5%) patients had chronic kidney disease (CKD) 3-5 stage. Preoperative risk stratification with EuroScore II scale was 9.4%. All operations performed in cardiopulmonary bypass; Custodial cardioplegia was used in 53 (48.1%) patients. The average perfusion time was 111 minutes, average cross-clamping time was 73.9 minutes. Acute kidney injury in the early postoperative period had 9 (8.1%) patients. Conclusions. At the admittance 38 (34.5%) patients with complicated forms of CAD had CKD 3-5 st. Analysis of the GFR dynamic in the early postoperative period shown a decrease in GFR in 71.05% of patients. Transient acute kidney injury with 50% sCr growth had 9 (8.1%) patients but didn’t require hemodialysis.
