Aim      To study the condition of coronary vasculature by data of coronarography (CG) in patients with chronic ischemic heart disease (IHD) and arterial hypertension (AH) associated with stage 2-4 chronic kidney disease (CKD) and to evaluate the effect of a 12-week complex treatment with perindopril or with a combination of perindopril/amlodipine on changes in vascular wall stiffness, endothelial function, and structure and function parameters in this patient category after coronary stenting.Material and methodsr This study included 87 patients with chronic IHD and AH associated with stage 2-3 CKD for whom CG was performed due to ineffectiveness of the antianginal therapy. The patients were divided into three subgroups: subgroup 1 included 28 patients who received a conservative treatment with perindopril 10 mg/day; subgroup 2 consisted of 25 patients who underwent coronary stenting and were prescribed perindopril; subgroup 3 consisted of 34 patients who underwent stenting and were prescribed the perindopril/amlodipine combination. The reference group included 47 patients with IHD and AH with preserved kidney function. Anatomic and functional parameters of the heart, arterial stiffness, pulse wave velocity, cardio-ankle vascular index, augmentation index, central aortic systolic and pulse pressure, endothelium-dependent vasodilation, plasma concentration of endothelin-1 (ET-1), and plasma concentration of nitric oxide metabolites were evaluated at baseline and after 12 weeks of treatment.Results In patients with IHD, AH, and stage 2-3 CKD, arterial stiffness was more pronounced than in patients with preserved kidney function. Concentrations of ET-1 were significantly higher and levels of nitric oxide were lower in CKD. Supplementing the complex therapy with perindopril resulted in a considerable hypotensive effect in all subgroups, improvement of the kidney function, and positive dynamics of arterial stiffness and endothelial function. Changes in these parameters were more pronounced in patients after coronary stenting than in patients receiving only a conservative treatment. The use of perindopril/amlodipine following stenting exerted the most significant angioprotective and cardioprotective effect.Conclusion      Patients with IHD and AH in combination with early CKD have pronounced impairment of the condition of arterial blood vessels and the heart. Addition of perindopril to the treatment not only exerted a hypotensive effect but also beneficially influenced mechanisms of progression of this combined pathology.

Abstract Background and Aims 24-h blood pressure (BP) may be superior to office BP in the prediction of cardiovascular mortality and also central aortic BP may better predict outcomes than brachial one. Hypertensive patients with type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD) have higher risk and poorer BP control than patients with normal glycemic state and renal function. 24-h profile of central BP and arterial stiffness according to CKD phenotypes are not well described in this population. The aim of the study was to evaluate the associations of kidney function and proteinuria with 24-h central BP and parameters of arterial stiffness in hypertensive patients with T2DM and CKD. Method 90 patients with hypertension (HTN), T2DM and CKD (eGFR 30-60 ml/min/1.73 m2 and morning spot urine albumin–creatinine ratio (UACR) <300 mg/g) were included. 66% of them were females, median age was 60 years, 69% were smokers, 53% obese, 77% with dyslipidemia. Median duration of T2DM and HTN was 7.5 years and 18 years, respectively. All received antihypertensive drugs (77% – combinations of 2 or 3 drugs) and glucose lowering therapy (insulin in 58%). The analysis was performed according to CKD phenotype: proteinuric (UACR 30-300 mg/g) and non-proteinuric (UACR <30 mg/g) and according to CKD stage assessed by GFR (G3a and G3b, KDIGO (2012)). Office brachial BP was measured with a validated oscillometric device. Office aortic BP and arterial stiffness were assessed with applanation tonometry (SphygmoCor AtCor). 24-hour ABPM of brachial and aortic BP was performed with BPLab Vasotens. All results are presented as median values. P<0.05 was considered significant. Results Median brachial BP was 156/83 mmHg, aortic BP 139/90 mmHg. Median eGFR was 53 ml/min/1.73 m2, UACR – 62.2 mg/g. Phenotypes of CKD were as follows: proteinuric in 78% (GFR 50 ml/min/1.73 m2, UACR 62 mg/g) and non-proteinuric in 22 % (GFR 54 ml/min/1.73 m2, med UACR 5 mg/g, p<0.01 for trend compared non-proteinuric). Patients with proteinuric phenotype compared to non-proteinuric were characterized by higher rate of dyslipidemia (85% vs 45%, p<0.001), longer duration of HTN and DM (19.5 vs 7.5 years and 8 vs 3 years, respectively, p <0.01 for trend) and lower HDL-C (1.2 vs 1.9, p=0.02). Both groups had similar office brachial SBP (156 vs 157 mmHg; p=0.48), but patients with proteinuric phenotype had higher office central SBP (147 vs 137 mmHg, p=0.007) and worse 24-h profile of central SBP (daytime 147 vs 138 mmHg, p=0.008; night-time 143 vs 130 mmHg, p=0.04). Proteinuric phenotype significantly correlated with office aortic SBP (r=0.28; p=0.01) and daytime and night-time aortic SBP (r=0.28 and 0.21 respectively, p <0.05 for trend). The eGFR phenotypes were as follows: G3a in 82.2% (GFR 54 ml/min/1.73 m2, UACR 20 mg/g) and G3b in 17.8% (GFR 38 ml/min/1.73 m2, med UACR 46 mg/g, p<0.01 for trend compared to G3a). Patients with worse kidney function had longer duration of HTN and DM (16 vs 11 years and 10 vs 6 years, respectively, p <0.01 for trend), higher median brachial and aortic BP levels (158/90 vs 146/82 mmHg and 150/95 vs 138/80 mmHg, respectively, p<0.01 for trend), worse 24-h profile of central SBP (daytime 148 vs 138 mmHg, p=0.008; night-time 146 vs 130 mmHg, p=0.006), higher central pulse pressure (56 vs 49 mmHg, p=0.007), augmentation index (33 vs 14%, p=0.007). Conclusion Hypertensive patients with T2DM and CKD G3b and proteinuria were characterized by worse 24-profile of central BP and higher arterial stiffness.

Abstract BACKGROUND Our aims were to assess whether arterial stiffness is associated with a higher risk for kidney dysfunction among persons without chronic kidney disease (CKD). METHODS We analyzed data from the national health checkup system in Japan; for our analyses, we selected records of individuals who completed assessments of cardio-ankle vascular index (CAVI) and kidney function from 2005 to 2016. We excluded participants who had CKD at baseline, defined as the presence of proteinuria or estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m2. We compared 2 groups of CAVI measurements—the highest quartile (≧8.1) and the combined lower 3 quartiles (<8.1). We used Cox proportional hazards models to assess associations between these 2 groups and subsequent CKD events, proteinuria, eGFR <60 ml/min/1.73 m2, and rapid eGFR decline (greater than or equal to −3 ml/min/1.73 m2 per year). RESULTS The mean age of the 24,297 included participants was 46.2 years, and 60% were female. Over a mean follow-up of 3.1 years, 1,435 CKD events occurred. In a multivariable analysis, the hazard ratios with 95% confidence intervals (CIs) for the highest vs. combined lower quartiles of CAVI measurements were 1.3 (1.1, 1.5) for CKD events, 1.3 (0.96, 1.62) for proteinuria, 1.4 (1.1, 1.7) for eGFR <60 ml/min/1.73 m2, and the odds ratio with 95% CI was 1.3 (1.1, 1.4) for rapid eGFR decline. CONCLUSIONS Persons with CAVI measurements ≧8.1 had a higher risk for CKD events compared with their counterparts with CAVI measurements <8.1. Greater arterial stiffness among adults without CKD may be associated with kidney dysfunction.

Cardiovascular disease (CVD) is common in chronic kidney disease (CKD), while major CV events are rare in young CKD patients. In addition to nitric oxide (NO)-related biomarkers, several surrogate markers have been assessed to stratify CV risk in youth with CKD, including 24-h ambulatory blood pressure monitoring (ABPM), carotid artery intima-media thickness (cIMT), pulse wave velocity (PWV), ABPM-derived arterial stiffness index (AASI), flow-mediated dilatation (FMD), and left ventricular mass index (LVMI). The aim of this study was to identify subclinical CVD through the analysis of indices of CV risk in children and adolescents with CKD. Between 2016 and 2018, the prospective observational study enrolled 125 patients aged 3 to 18 years with G1–G4 CKD stages. Close to two-thirds of young patients with CKD exhibited blood pressure (BP) abnormalities on ABPM. CKD children with abnormal office BP showed lower plasma arginine levels and arginine-to-asymmetric dimethylarginine (ADMA) ratio, but higher ratios of ADMA-to-symmetric dimethylarginine (SDMA) and citrulline-to-arginine. High PWV and AASI, indices of arterial stiffness, both strongly correlated with high BP load. Additionally, LV mass and LVMI exhibited strong correlations with high BP load. Using an adjusted regression model, we observed the citrulline-to-arginine ratio was associated with 24-h systolic and diastolic BP, systolic blood pressure (SBP) load, and diastolic blood pressure (DBP) load. Early assessments of NO-related parameters, BP load abnormalities, arterial stiffness indices, and LV mass will aid in early preventative care toward decreasing CV risk later in life for children and adolescents with CKD.

ABSTRACT Chronic kidney disease (CKD) is a multifactorial pathophysiologic irreversible process that often leads to a terminal state in which the patient requires renal replacement therapy. Most cases of CKD are due to chronic-degenerative diseases and endothelial dysfunction is one of the factors that contribute to its pathophysiology. One of the most important mechanisms for proper functioning of the endothelium is the regulation of the synthesis of nitric oxide. This compound is synthesized by the enzyme nitric oxide synthase, which has 3 isoforms. Polymorphisms in the NOS3 gene have been implicated as factors that alter the homeostasis of this mechanism. The Glu298Asp polymorphisms 4 b/a and -786T>C of the NOS3 gene have been associated with a more rapid deterioration of kidney function in patients with CKD. These polymorphisms have been evaluated in patients with CKD of determined and undetermined etiology and related to a more rapid deterioration of kidney function.
