Insights

Haemodialysis significantly reduces myocardial blood flow (MBF) and left ventricular (LV) function, even early in the procedure. These reductions in MBF during haemodialysis may contribute to the elevated cardiac risk observed in dialysis patients.

Area of Science:

  • Cardiology
  • Nephrology
  • Nuclear Medicine

Background:

  • Haemodialysis (HD) is essential for renal replacement therapy but is linked to increased cardiac risk and sudden death in patients.
  • Accumulating evidence suggests the HD procedure itself can induce myocardial ischemia.

Purpose of the Study:

  • To evaluate the impact of HD on global and regional myocardial blood flow (MBF) and left ventricular (LV) function.
  • To assess these effects in non-diabetic patients without pre-existing cardiac compromise.

Main Methods:

  • Utilized (13)N-ammonia positron emission tomography (PET) to quantify MBF, LV wall motion, cardiac output (CO), LV end-diastolic volume (LVEDV), and LV end-systolic volume (LVESV).
  • PET scans were conducted before and at 30 and 220 minutes during HD in seven patients.

Main Results:

  • Global MBF decreased significantly during HD, falling by 13.5% at 30 minutes and 26.6% at 220 minutes (after ultrafiltration).
  • LV volumes (LVEDV, LVESV) and CO also showed significant reductions during HD.
  • New LV regional wall motion abnormalities (RWMA) developed in two patients, correlating with greater MBF reduction in affected regions.

Conclusions:

  • Haemodialysis induces a substantial and early reduction in MBF.
  • Factors beyond hypovolemia, such as acute dialysis-associated elements, contribute to decreased MBF.
  • Reduced MBF during HD may be a significant factor in the high cardiac event rate among dialysis patients.

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 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...

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...

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...

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...

Heart Failure Drugs: Diuretics

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...
