Insights

Chronic hemodialysis patients in Brazil exhibit a high prevalence of cardiovascular risk factors, including hypertension and dyslipidemia. These findings highlight the urgent need for targeted interventions to mitigate cardiovascular disease in this vulnerable population.

Area of Science:

  • Cardiology
  • Nephrology
  • Epidemiology

Background:

  • Limited epidemiological data exists on the cardiovascular risk profile of chronic hemodialysis patients in Brazil.
  • The CORDIAL study addresses this gap by investigating cardiovascular risk factors in a Brazilian hemodialysis population.

Purpose of the Study:

  • To evaluate the cardiovascular risk profile of patients undergoing chronic hemodialysis in a major Brazilian metropolitan area.
  • To identify prevalent cardiovascular risk factors and their associations within this patient cohort.

Main Methods:

  • The CORDIAL study enrolled 1215 patients from all fifteen nephrology centers in Porto Alegre, Brazil.
  • Data collection involved reviewing medical records and conducting structured interviews to gather clinical, laboratory, and demographic information.

Main Results:

  • A high prevalence of cardiovascular risk factors was observed: hypertension (87.5%), dyslipidemia (84.7%), sedentary lifestyle (73.1%), tobacco use (53.7%), and diabetes (35.8%).
  • Sedentary lifestyle, dyslipidemia, and obesity were more common in women, while hypertension and tobacco use were more prevalent in patients under 65.
  • Sedentary lifestyle was independently associated with a dialysis duration of less than 12 months.

Conclusions:

  • Hemodialysis patients in this Brazilian metropolitan city present a high burden of cardiovascular risk factors.
  • The observed risk profile resembles that found in hemodialysis populations in many northern countries, indicating a need for comparable preventive strategies.

Hemodialysis II: Procedure and Complications

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

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...

Hemodialysis I: Introduction01:25

Hemodialysis I: Introduction

Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

Hemodialysis III: Nursing Management

The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this...

Chronic Kidney Disease I: Introduction01:25

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...

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...
