Introduction: The prevalence of hypertension among patients with end-stage kidney disease (ESKD) undergoing hemodialysis (HD) ranges from 72 to 88% depending on applied diagnostic criteria and the chosen method of blood pressure measurement. Despite the guidelines recommending the widespread use of renin-angiotensin system blockers (RASBs) in patients with kidney disease, their utilization in patients on HD may be suboptimal, especially in patients with preserved diuresis. This hesitance that often steams from concern is often due to fear of a decrease in eGFR and a subsequent decrease in diuresis.

Hypertension is the most common finding in chronic kidney disease patients, with prevalence ranging from 60% to 90% depending on the stage and etiology of the disease. It is also a significant independent risk factor for cardiovascular disease, progression to end-stage kidney disease and mortality. According to the current guidelines, resistant hypertension is defined in the general population as uncontrolled blood pressure on three or more antihypertensive drugs in adequate doses or when patients are on four or more antihypertensive drug categories irrespective of the blood pressure control, providing that antihypertensive treatment included diuretics.

Background: Renal artery stenosis (RAS) reflects more widespread atherosclerosis deposition and is associated with high morbidity and mortality. According to the guidelines, a discrepancy in the size of the kidneys of over 15 mm found in an ultrasound should initiate the RAS diagnostic algorithm. This study aims to find the optimal threshold for renal asymmetry that better reflects the frequency of a significantly abnormal renal-aortic ratio (RAR), justifying further RAS diagnostic workup, than the currently used cut-off of 15 mm difference in renal diameters.

Primary aldosteronism (PA) is a potentially curable form of secondary hypertension caused by excessive renin-independent aldosterone secretion, leading to increased target organ damage and cardiovascular morbidity and mortality. The diagnosis of PA requires measuring renin and aldosterone to calculate the aldosterone-to-renin ratio, followed by confirmatory tests to demonstrate renin-independent aldosterone secretion and/or PA subtype differentiation. Various antihypertensive drug classes interfere with the renin-angiotensin-aldosterone axis and hence evaluation for PA should ideally be performed off-drugs.

Purpose: Differences between the regions of the same country regarding the management of abdominal aortic aneurysm (AAA) have rarely been published. The aim of the study was to analyze the absolute and relative number of unruptured AAA repairs, utilizing endovascular aneurysm repair (EVAR) vs. open aneurysm repairs (OAR) and compare the AAA patients population from all 16 administrative districts in Poland.

Objective: Studies indicates that dysregulation of emotions plays an important role in the etiology of elevated blood pressure (BP). One of the signatures of emotional dysregulation is alexithymia defined as an impaired ability to experience and express emotions. Previous work indicated that primary hypertension (HT) is marked by higher alexithymia, but little research examined the relationship between alexithymia and variability of evaluated BP with 24 h Ambulatory Blood Pressure Monitoring (ABPM) in HT patients.

Owing to inconvenience of a 24‑hour urine collection, diagnostic methods based on spot urine samples are becoming increasingly popular. Spot urine sodium measurements could replace 24‑hour urinary sodium (24hUNa) excretion, considered a surrogate measure of dietary sodium intake. Spot urine-based approaches to estimating 24hUNa and 24‑hour urinary potassium (24hUK) excretion are potentially useful in patients with hypertension, for example, to identify increased urinary potassium excretion in individuals with primary aldosteronism and high dietary sodium intake in those with resistant hypertension.

Estimated 24-hour urinary creatinine excretion (24 hrUCr) may be useful for converting spot urine analyte/creatinine ratio into estimated 24-hour urinary excretion of the evaluated analyte, and for verifying completeness of 24-hour urinary collections. We compared various published 24 hrUCr-estimating equations against measured 24 hrUCr in hospitalized hypertensive patients. 24 hrUCr was measured in 293 patients and estimated using eight formulas (CKD-EPI, Cockcroft-Gault, Walser, Goldwasser, Rule, Gerber-Mann, Kawasaki, Tanaka).

Background Hypertension is the most prevalent and leading risk factor for stroke. SPRINT (The Systolic Blood Pressure Intervention Trial) assessed the effects on cardiovascular event risk of intensive compared with standard systolic blood pressure reduction. In this secondary analysis of SPRINT data, we investigated how low on-treatment diastolic blood pressure ( DBP ) influenced risk for stroke events.

Background: Measurements of glycated hemoglobin (HbA1c) in non-diabetics can identify subjects who are at increased risk for future cardiovascular (CV) events. There is no consensus agreement whether the addition of HbA1c improves the CV risk prediction.

Objectives: The objective of this study was to assess mean values of HbA1c levels in a representative sample of general, diabetes mellitus (DM)-free Polish population, and its subgroups, and to identify important covariants.

Measurements of 24-hour urinary sodium (24hrUNa) and potassium (24hrUK) excretion are useful in hypertensives but 24-hour urine collection may be difficult or unreliable. We compared three formulas (Tanaka, Kawasaki, Pan American Health Organization [PAHO]) proposed to estimate 24hrUNa and 24hrUK based on spot urine measurements. We studied 382 patients admitted to a hypertension unit.

Objective: Beyond lipid-lowering properties, statins decrease sympathetic nervous activity. Due to the limited number of studies and included participants, a meta-analysis of randomized, placebo-controlled studies using microneurography (MSNA) was performed to assess sympatholytic effect of statins.

Methods: We conducted a comprehensive search of online databases (Cochrane, Embase, and EBSCO) for published human studies up to April 2014.

The relationship between the sympatholytic effects of statins and their lipid-lowering activity remains unclear. Ezetimibe lowers cholesterol, but its sympatholytic activity is unknown. The purpose of study was to compare the influence of equipotent doses of simvastatin and ezetimibe on sympathetic activity.

Previous studies have shown that hyperoxia-induced deactivation of carotid body chemoreceptors reduces sympathetic activity in hypertensive patients but it does not affect blood pressure. The maintenance of blood pressure can be explained by the direct, vasoconstrictive effect of hyperoxia, which offsets diminished sympathetic activity. This study compares the effect of acute hyperoxia on hemodynamic parameters between hypertensive and normotensive subjects.

Introduction: Childhood hypertension is defined based on the normative distribution of blood pressure (BP), but from the age of 18 years high BP is diagnosed using adult criteria. We compared the rates of diagnosis of hypertension in a group of 18-year-old subjects using BP percentiles and the adult criteria.

Material And Methods: Blood pressure was measured by registered nurses in 1472 18-year-old high-school students (780 men and 692 women).
