Insights

Patients on maintenance haemodialysis often have impaired cardiac function. This study found significant left ventricular diastolic dysfunction in 77.5% of haemodialysis patients compared to healthy controls.

Area of Science:

  • Cardiology
  • Nephrology
  • Echocardiography

Background:

  • Cardiac dysfunction is common in patients undergoing maintenance haemodialysis.
  • Left ventricular diastolic function is a critical aspect of cardiac health.

Purpose of the Study:

  • To evaluate left ventricular diastolic function in patients receiving maintenance haemodialysis.
  • To compare diastolic function between haemodialysis patients and healthy individuals.

Main Methods:

  • Utilized 2D and pulsed wave Doppler echocardiography.
  • Assessed diastolic function in 40 patients on maintenance haemodialysis.
  • Included a control group of healthy individuals for comparison.

Main Results:

  • Significant alterations in Doppler parameters were observed in haemodialysis patients.
  • Diastolic dysfunction was identified in 77.5% of the haemodialysis group.
  • Haemodialysis patients exhibited increased peak late diastolic filling velocity (A wave) and reduced E/A ratio compared to controls.

Conclusions:

  • Maintenance haemodialysis is associated with significant impairment of left ventricular diastolic function.
  • Doppler echocardiography effectively identified diastolic dysfunction in this patient population.

Dialysis

Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...

Dialysis

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

Heart Failure II: Pathophysiology

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

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,...

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 measurement...

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 fluid...
