Insights

Ambulatory blood pressure monitoring (ABPM) is crucial for diagnosing nondipping in hypertension patients with chronic kidney disease (CKD). This review examines ABPM

Area of Science:

  • Nephrology
  • Cardiology
  • Hypertension Management

Background:

  • Hypertension and chronic kidney disease (CKD) frequently coexist, increasing cardiovascular risks.
  • Nondipping, a loss of the normal nighttime blood pressure fall, is diagnosed by ambulatory blood pressure monitoring (ABPM) and is a cardiovascular risk factor.
  • CKD is an independent risk factor for nondipping, observed in up to 80% of patients.

Purpose of the Study:

  • To review the evidence for using ABPM in CKD patients.
  • To examine the link between ABPM patterns and patient outcomes in CKD.
  • To assess the evidence for treating nondipping in CKD.

Main Methods:

  • Literature review of studies on ABPM in CKD.
  • Analysis of evidence linking ABPM-derived hypertension patterns to CKD prognosis.
  • Evaluation of treatment strategies for nondipping in the context of CKD.

Main Results:

  • ABPM is superior to clinical BP measurement for correlating with end-organ damage and prognosis in CKD.
  • Nondipping is highly prevalent in CKD patients.
  • Evidence linking nondipping to adverse outcomes in CKD is mixed, necessitating further research.

Conclusions:

  • ABPM is a valuable tool for assessing cardiovascular risk in CKD patients.
  • Further research is needed to clarify the independent prognostic role of nondipping in CKD.
  • Optimizing ABPM use and treatment of nondipping may improve CKD outcomes.

Chronic Kidney Disease I: Introduction

Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Chronic Kidney Disease IV: Nursing Management

Nursing management is essential for preventing complications, maintaining stability, and improving patients' quality of life in chronic kidney disease (CKD). By using a structured approach, nurses help slow CKD progression and support effective patient care​.1. Comprehensive patient assessmentEffective management begins with nurses reviewing the patient’s medical history, and identifying key risk factors like diabetes, hypertension, and nephrotoxic drug use. Nurses assess signs of...

Hypertension III: Clinical Manifestations and Diagnostic Studies

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Hypertension and Regulation of Blood Pressure01:18

Hypertension and Regulation of Blood Pressure

Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...
