Relation between carotid intimal medial thickness and left ventricular mass and left ventricular mass indices in...

Area of Science:

• Nephrology
• Cardiology
• Vascular Biology

Background:

• Left ventricular hypertrophy (LVH) is a significant risk factor for cardiovascular complications in patients undergoing dialysis.
• Increased hemodynamic load in dialysis patients may link LV mass and carotid intimal medial thickness (CIMT).
• Understanding the relationship between CIMT and LV mass indices is crucial for assessing cardiovascular risk in hemodialysis (HD) patients.

Purpose of the Study:

• To investigate the relationship between carotid intimal medial thickness (CIMT) and left ventricular mass (LVM) indices in patients undergoing maintenance hemodialysis.
• To determine if CIMT is an independent predictor of LVH in this patient cohort.

Main Methods:

• A cross-sectional study involving 65 hemodialysis patients, categorized into two groups based on CIMT measurements (≤1 mm and >1 mm).
• Echocardiography was used to assess Left Ventricular Mass (LVM).
• Carotid intimal medial thickness (CIMT) was measured using B-mode ultrasonography. Clinical and biochemical data were also collected.

Main Results:

• Patients with CIMT > 1 mm exhibited significantly higher LVM, LVM indexed to body surface area (LVM/BSA), and LVM indexed to height (LVM/Ht^2.7).
• Linear regression analysis identified CIMT as an independent predictor for LVM, LVM/BSA, and LVM/Ht^2.7.
• Elevated LVM, LVMI, and LVM/Ht^2.7 were observed in the HD patient group with CIMT > 1 mm.

Conclusions:

• Carotid intimal medial thickness (CIMT) is a significant independent predictor of left ventricular hypertrophy (LVH) in patients on maintenance hemodialysis.
• CIMT measurement can serve as a valuable non-invasive marker for assessing LVH and associated cardiovascular risk in HD patients.
