Summary
Hemodialysis (HD) can cause left ventricular (LV) systolic dysfunction in most patients, leading to regional wall motion abnormalities (RWMAs). Better interdialytic weight gain management is crucial for reducing this risk.
Area of Science:
- Cardiology
- Nephrology
- Medical Imaging
Background:
- Hemodialysis (HD) patients exhibit high cardiovascular mortality, often linked to cardiac dysfunction.
- Repetitive myocardial ischemia during HD can induce left ventricular (LV) systolic dysfunction.
- Understanding HD-induced cardiac dysfunction is vital for improving patient outcomes.
Purpose of the Study:
- To evaluate the prevalence of HD-induced LV systolic dysfunction.
- To identify potential risk factors associated with this dysfunction.
- To provide evidence for clinical strategies to mitigate cardiac risks in HD patients.
Main Methods:
- 31 standard HD patients underwent echocardiography before, during, and after dialysis.
- Auto functional imaging (AFI) assessed regional wall motion abnormalities (RWMAs).
- Biochemical variables and interdialytic weight gain (IDWG) were analyzed.
Main Results:
- 93.54% of patients and 51.40% of myocardial segments showed RWMAs.
- Severe RWMAs were associated with higher cTnT, phosphate, UFR, and lower albumin levels.
- Interdialytic weight gain (IDWG) was identified as an independent risk factor for severe RWMAs.
Conclusions:
- HD-induced LV systolic dysfunction is highly prevalent in HD patients.
- Effective interdialytic weight management is essential to reduce ultrafiltration rates and mitigate RWMAs.
- Clinical strategies should focus on weight control to prevent cardiac complications in HD patients.

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...

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,...

Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

01:20Mitral Regurgitation I: Introduction
892
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

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...

Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...
