Blood pressure measurement in haemodialysis patients

Several studies suggest that the 24 hour ambulatory blood pressure monitoring (ABPM) predicts left ventricular hypertrophy more accurately than conventional blood pressure measurement (CBPM) with mercury sphygmomanometer. We estimated the left ventricular mass by M-mode echocardiography in 58 patients on regular haemodialysis treatment during the midweek haemodialysis (HD) interval. ABPM was recorded during the 24 hours preceding the dialysis session and the average of values were compared with the average of the 13 pre HD CBPM recorded by nurses during the month preceding the echocardiography study. The two types of BP measurements correlated significantly with each other, (systolic BP r = 0.62; p < 0.001 and diastolic BP r = 0.74; p < 0.001). The correlation of left ventricular mass with pre-HD systolic BP was stronger (r = 0.54; p < 0.001) than with 24h-systolic BP (r = 0.33; p < 0.01). The overall accuracy of prediction was also similar (68% for pre HD-CBPM; 67% for 24h-ABPM). Measurements of diastolic BP did not correlate significantly with LVM. Our data suggest that 24h-ABPM does not offer any advantage over pre HD-CBPM in predicting left ventricular hypertrophy in HD patients.
