In addition, circadian BP variability was better associated with HT‐induced end‐organ damage in dialysis patients. A continuous 24 h measurement of BP can be performed by ABPM, providing a superior assessment of BP control. Īmbulatory blood pressure monitoring (ABPM) has several advantages over office blood pressure (BP) measurements. A recent study suggested that CAPD patients were more volume overloaded and had higher prevalence of left ventricular hypertrophy (LVH) compared with haemodialysis (HD) patients. Additionally, patients on long‐term CAPD had higher left ventricular mass. Įarlier studies suggested that patients on long‐term CAPD treatment were more volume overloaded than patients on short‐term CAPD. The measurement of inferior vena cava diameter (IVCD) is now accepted as a reliable non‐invasive technique to determine volume status in dialysis patients.

Volume overload has been associated with increased prevalence of uncontrolled HT in end‐stage renal disease (ESRD) patients. In these patients, the prevalence of hypertension (HT) is high and ranges from 29% to 88%. Further long‐term prospective studies examining effects of salt restriction and ultrafiltration on BP control and left ventricle wall thickness are warranted.ĬAPD, hypertension, inferior vena cava diameter (index), left ventricular hypertrophy, plasma volume overload IntroductionĬardiovascular diseases are the most common causes of morbidity and mortality in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). Stepwise multiple regression analysis revealed that 24 h diastolic BP and haemoglobin were independent determinants of LVMI.Ĭonclusion. Uncontrolled HT on background therapy is highly prevalent among volume overloaded CAPD patients. The LVMI was also higher in Group A than in Group B (145☓9 vs 118☓4 g/m 2, P<0.01). There was no correlation between IVCD index and office BP, ABPM measurements or LVMI. The IVCD index was higher in Group A than in Group B (9.2☒.1 vs 7.7☑.9 mm/m 2, P=0.007). Patients with uncontrolled HT (Group A) were taking more antihypertensive medications than patients with ‘normotension and controlled HT’ (Group B, n=20 1.0☐.8 vs 0.5☐.7, P=0.008). The prevalence of ‘uncontrolled HT’ measured by ABPM was 73% ( n=54). Daytime BP was 147/92 mm Hg by office measurements and 145/91 mm Hg by ABPM ( P>0.05). Results. The prevalence of HT was 84% when using office measurements and 82% when using daytime ABPM. Intravascular volume status was determined using the IVCD index and collapsibility index (CI) on the same day as ABPM. Patients undergoing CAPD were categorized into two groups: ‘uncontrolled HT’ (Group A) and ‘normotensive and controlled HT’ (Group B). All patients underwent echocardiographic examination and received ABPM. Methods. Seventy‐four CAPD patients were included in the final analysis. We further determined whether intravascular volume status, assessed by inferior vena cava diameter (IVCD) index, contributes to higher blood pressure (BP) and increased left ventricular mass index (LVMI). In this study, we aimed to determine the prevalence of ‘uncontrolled HT’ during background therapy in CAPD patients by using office measurements and ambulatory blood pressure monitoring (ABPM).

Background. Hypertension (HT) is common in patients on continuous ambulatory peritoneal dialysis (CAPD) and is responsible for increased cardiovascular morbidity and mortality.
