AI Article Synopsis
- The study investigates the link between urine sodium-to-potassium (Na/K) ratio and uncontrolled hypertension (HTN), indicating that an imbalanced Na/K ratio could contribute to higher blood pressure.
- Data from over 5,700 participants with diagnosed HTN showed that higher urine Na/K correlates with increased systolic and mean arterial pressure, significantly raising the risk of uncontrolled HTN.
- The results suggest that monitoring the urine Na/K ratio could be a useful strategy for identifying individuals at risk for uncontrolled HTN, particularly in those with chronic kidney disease.
Article Abstract
Background: Hypertension (HTN) is linked to an enhanced risk of chronic kidney disease and cardiovascular disease. While sodium and potassium intake affect blood pressure (BP) control, the urine sodium-to-potassium (Na/K) ratio, which reflects dietary balance and renal regulation of these electrolytes, could be associated with BP. This study aimed to evaluate the independent association between urine Na/K and uncontrolled HTN.
Methods: Data were collected from the Korea National Health and Nutrition Examination Survey from 2016 to 2021. A total of 5,770 participants diagnosed with HTN were enrolled in this study. Uncontrolled HTN was characterized by a systolic blood pressure (SBP) ≥ 140 mmHg or diastolic blood pressure (DBP) ≥ 90 mmHg. Logistic regression analysis was used to assess the relationship between urine Na/K and the risk of uncontrolled HTN.
Results: The urine Na/K was positively correlated with both SBP and mean arterial pressure. Higher urine Na/K was significantly associated with an increased risk of uncontrolled HTN using both continuous (odds ratio [95% confidence interval] 1.13 [1.09-1.16], P <0.01]) and across quartile values (with Q1 as a reference; Q2: 1.26 [1.06-1.49], P = 0.01; Q3: 1.50 [1.27-1.78], P <0.01; Q4: 1.85 [1.55-2.17], P < 0.01). The subgroup analysis also showed that higher urine Na/K were significantly related to the risk of uncontrolled HTN in the presence of proteinuria or CKD.
Conclusion: Urine Na/K ratio is independently associated with uncontrolled HTN in the general population and in patients with CKD. Our findings suggest that monitoring the urine Na/K could serve as an effective tool for identifying subjects at risk of uncontrolled HTN.

Measurement of Blood Pressure in Children and Adolescents Outside the Office for the Diagnosis of Hypertension.
Curr Cardiol Rep
January 2025
Section of Pediatric Nephrology, Department of Pediatrics, Yale University School of Medicine, New Haven, USA.
Purpose Of Review: To review the benefits of ambulatory blood pressure monitoring and home blood pressure monitoring in children and to discuss implementation of guideline-recommended ambulatory blood pressure monitoring.
Recent Findings: Compared with office blood pressure, ambulatory blood pressure monitoring and home blood pressure monitoring provide superior accuracy, reproducibility, and stronger associations with target organ damage although future work is needed to determine the utility of home blood pressure monitoring to predict hypertension status on ambulatory blood pressure monitoring. Due to the benefits of out-of-office blood pressure measurement, ambulatory blood pressure monitoring has been recommended to confirm the diagnosis of hypertension in children and adolescents since publication of the 2017 American Academy of Pediatrics clinical practice guidelines on hypertension.
Screening of primary aldosteronism and pheochromocytoma among patients with hypertension: an Italian nationwide survey.

Division of Internal Medicine 4 and Hypertension Unit, Department of Medical Sciences, University of Torino, Torino, Italy.
Purpose: The delayed or missed diagnosis of secondary hypertension contributes to the poor blood pressure control worldwide. This study aimed to assess the diagnostic approach to primary aldosteronism (PA) and pheochromocytoma (PHEO) among Italian centers associated to European and Italian Societies of Hypertension.
Methods: Between July and December 2023, a 10-items questionnaire was administered to experts from 82 centers of 14 Italian regions and to cardiologists from the ARCA (Associazioni Regionali Cardiologi Ambulatoriali) Piemonte.

Background: Cold agglutinin disease (CAD) is an autoimmune hemolytic anemia that induces blood coagulation and hemolysis upon exposure to cold temperatures. Strict temperature control is essential to mitigate these effects, especially during surgical procedures where hypothermia is possible.
Case Presentation: A 57-year-old male, 165 cm and 72 kg, diagnosed with CAD, underwent cerebral vascular anastomosis.

Department of Internal Medicine, Aristotle University, Hypertension, Hypertension-24h ambulatory blood pressure monitoring center, Papageorgiou Hospital, Thessaloniki, Greece.
Purpose Of The Review: Τhe association between nocturnal blood pressure (BP) and alterations in the retinal microvasculature remains understudied, with few available studies to provide conflicting results. Therefore, we conducted a systematic review and meta-analysis to determine whether an association exists between retinal microvascular alterations and nocturnal BP patterns, determined by 24h ambulatory BP measurement.
Recent Findings: Our search concluded to 1002 patients (6 studies).
