Is There any Time Dependant Echocardiographical Finding in Chronic Hemodialysis Patients?
Abstract
Methods: In a cross-sectional study, 100 adult hemodialysis patients (51% male and 49% female with mean age 52.13 12.69 years) visiting dialysis unit in Imam Reza and Madani hospitals between years 2010 and 2011 were studied in group 1 (hemodialysis <= 6 months), group 2 (hemodialysis for 6 months to 3 years) and group 3 (hemodialysis >=3 years). Demographic, laboratory and echocardiographic findings were compared between groups.
Results: Among demographic findings, group 3 had significantly higher diastolic blood pressure and weight gain and was older than other two groups (P < 0.05). By increase in hemodialysis period, patients had higher blood urea nitrogen and lower serum albumin levels (P < 0.05). Potassium level in group 2 was significantly higher than group 3 and that was higher than group 1. There was no difference between groups in left ventricular hypertrophy (LVH), left atrium dilatation, ejection fraction and mitral insufficiency. Diastolic dysfunction increased in line with increase in hemodialysis period (P = 0.007). Hemodialysis period was higher in patients with LVH than those without (34.80 9.2 months versus 18.51 2.22 months, P = 0.01).
Conclusion: In hemodialysis patients, diastolic dysfunction increases by the hemodialysis time (years). LVH and LA dilation also increase during time, but not significantly.
