Insights

Autosomal dominant polycystic kidney disease (ADPKD) patients show normal ambulatory pulse pressure (PP). PP increases with age and male sex, and decreases with kidney function, but is not linked to hypertension diagnosis.

Area of Science:

  • Cardiology
  • Nephrology
  • Hypertension Research

Background:

  • Pulse pressure (PP) is a key blood pressure component linked to arterial stiffness and prognosis.
  • Autosomal dominant polycystic kidney disease (ADPKD) involves multifactorial cardiovascular issues, suggesting potential for increased PP.

Purpose of the Study:

  • Investigate ambulatory PP in ADPKD patients.
  • Examine the influence of age, sex, kidney function, hypertension, circadian rhythm, and antihypertensive drugs on PP in ADPKD.

Main Methods:

  • Retrospective analysis of 24-hour ambulatory blood pressure monitoring in 130 ADPKD patients.
  • Data collected included demographics, medical history, antihypertensive treatment, and estimated glomerular filtration rate (eGFR).
  • ADPKD diagnosis followed Pei et al. criteria; eGFR calculated using CKD-EPI equation.

Main Results:

  • Mean PP was 46 mm Hg, higher in men and during daytime versus nighttime.
  • PP showed negative correlation with eGFR and positive correlation with age.
  • No significant difference in PP between ADPKD patients with or without hypertension diagnosis.

Conclusions:

  • Ambulatory PP is not substantially elevated in ADPKD patients across CKD stages.
  • PP patterns in ADPKD align with expected physiological changes: increasing with age, male sex, daytime, and decreasing eGFR.
  • Hypertension diagnosis did not significantly impact PP levels in this ADPKD cohort.

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...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

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...

Peripheral Artery Disease I: Introduction01:30

Peripheral Artery Disease I: Introduction

Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

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...

Pulse01:16

Pulse

When the heart pumps blood out, arterial elastic fibers play a crucial role in sustaining a high-pressure gradient. They expand to accommodate the received blood and then recoil - a process known as the pulse that can be either manually palpated or electronically quantified. Despite a reduction in its effect with increased distance from the heart, elements of the pulse's systolic and diastolic components persist, observable even at the arteriole level.
The pulse serves as a clinical...
