İt was aimed to study whether ABPM is necessary in the assessment of blood pressure (BP) control in CAPD patients or not for this reason BP levels measured by clinically were compared to the levels of ABPM technique.
Twenty five CAPD patients (14 F, 11M) aged 47 ± 14 (16-71) years were included in the study. Mean dialysis duration was 22.9 ± 18 month. Ten patients (40%) were using antihypertensive drugs. Clinical BP levels were measured by manually two times after a 5- minutes of rest. Then 24 hour ABPM was applied to the patient. The patients who had a BP level above 140/90 mmHg according to clinical measurement and had a BP level above 135/85 mmHg according to ABPM were considered as hypertensive and the patients whose BP levels reduced less than 10% in night-time were considered as non-dippers.
Systolic and diastolic BP levels measured by clinically were higher than those of ABPM technique (137.8±20 / 91.0±12.7 mmHg vs 130.8±18.6 / 84.4±14.4). But the differences were not significant (p>0.05). While 12 patients (48%) were hypertensive by manual measurements, Eight patients (32%) were hypertensive by ABPM (p>0.05).
While day-time BP levels were 140.4 ±20/ 89.6 ± 14 mmHg, night time BP levels were 120.8 ± 18.7/77.2 ± 75 mmHg according to ABPM results (p<0.0001 for both). Six of 10 patients using antihypertensive drugs were still hypertensive. A normal diurnal variation was found in 80% of the patients.
Clinical blood pressure levels measured manually were similar to the BP levels measured by ABPM technigue. Therefore, we think that ABPM is not necessary in the routine assesment of blood pressure control in CAPD patients but it may be used in dipper-nondipper distinction.
