1. Electrocardiographic parameters of left ventricular
hypertrophy and prediction of mortality in hemodialysis
patients

2. INTRODUCTION:
In hemodialysis patients, left ventricular hypertrophy (LVH)
contributes to high cardiovascular mortality. We
examined cardiovascular mortality prediction by the recently
proposed Peguero-Lo Presti voltage since it identifes more
patients with electrocardiographic (ECG) LVH than Cornell or
Sokolow-Lyon voltages.

3. METHODS
• A total of 308 patients on hemodialysis underwent 24 h ECG
recordings.
• LVH parameters were measured before and after dialysis.
• The primary endpoint of cardiovascular mortality was recorded
during a median 3-year follow up.
• Risk prediction was assessed by Cox regression, both unadjusted and
adjusted for the Charlson Comorbidity Index and the Cardiovascular
Mortality Risk Score.

4. • Inclusion criteria :
1. All participants gave written informed consent.
2. Inclusion criteria were age ≥ 18 years and dialysis vintage≥90 days
• Exclusion criteria :
1. Age below 18 years
2. Pregnant/postpartum females
3. ongoing infection or malignancy with life expectancy less than 24 months
