This article is from Cardiovascular Journal of Africa, volume 25.AbstractIntroduction: Central aortic systolic pressure CASP strongly predicts cardiovascular outcomes. We undertook to measure ambulatory CASP in 74 prevalent dialysis patients using the BPro HealthStats, Singapore device. We also determined whether coronary or abdominal aortic calcification was associated with changes in CASP and whether interdialytic CASP predicted ambulatory measurement. Methods: All patients underwent computed tomography for coronary calcium score, lateral abdominal radiography for aortic calcium score, echocardiography for left ventricular mass index and ambulatory blood pressure measurement using BPro calibrated to brachial blood pressure. HealthStats was able to convert standard BPro SOFT® data into ambulatory CASP. Results: Ambulatory CASP was not different in those without and with coronary 137.6 vs 141.8 mmHg, respectively, p = 0.6 or aortic 136.6 vs 145.6 mmHg, respectively, p = 0.2 calcification. Furthermore, when expressed as a percentage of brachial systolic blood pressure to control for peripheral blood pressure, any difference in CASP was abolished: CASP: brachial systolic blood pressure ratio = 0.9 across all categories regardless of the presence of coronary or aortic calcification p = 0.2 and 0.4, respectively. Supporting this finding, left ventricular mass index was also not different in those with or without vascular calcification p = 0.7 and 0.8 for coronary and aortic calcification. Inter-dialytic office blood pressure and CASP correlated excellently with ambulatory measurements r = 0.9 for both. Conclusion: Vascular calcification was not associated with changes in ambulatory central aortic systolic pressure in this cohort of prevalent dialysis patients. Inter-dialytic blood pressure and CASP correlated very well with ambulatory measurement.
