Impact of intradialytic blood pressure changes on cardiovascular outcomes is independent of the volume status of maintenance hemodialysis patients

Impacts of Coronary Artery Calcification on Intradialytic Blood Pressure Patterns in Patients Receiving Maintenance Hemodialysis

Intradialytic blood pressure abnormalities are associated with adverse outcomes in patients with end-stage renal disease on dialysis. Vascular calcification is a common complicating feature, but whether this complication results in intradialytic blood pressure abnormalities remains uncertain. Therefore, this study investigated the relationship between coronary artery calcium score and intradialytic blood pressure abnormalities in patients with end-stage renal disease on maintenance hemodialysis. Thirty-six patients who received nongated chest computed tomography scans were included. Intradialytic hypotension was defined as a minimum intradialytic systolic blood pressure of <100 mmHg or a pre-dialysis blood pressure – minimum intradialytic systolic blood pressure >30 mmHg. Intradialytic hypertension was defined as >10 mmHg increase in systolic blood pressure (pre- to post-dialysis). Patients were classified as 22 (61.1%) with coronary artery calcium score <400 and 14 (38.9%) with coronary artery calcium score ≥400. Median systolic and diastolic blood pressures were equivalent, but median pulse pressure was higher in patients with coronary artery calcium score ≥400 than in those with scores <400. Coronary artery calcium score was comparable according to both intradialytic hypotension and hypertension, and had no correlation with systolic blood pressure fall and nadir systolic blood pressure. Coronary artery calcium score predicted the occurrence of cardiovascular events and all-cause mortality (hazard ratio 1.001 and 1.001; p=0.058 and 0.010). Coronary vascular calcification could be irrelevant to intradialytic blood pressure abnormalities in patients with end-stage renal disease on dialysis.

The Comparison of Progressive Muscle Relaxation Frequency on Anxiety, Blood Pressure, and Pulse of Haemodialysis Patients

Introduction: Haemodialysis is one of the kidney replacements therapies, but, as it cannot wholly replace kidney function, it still causes complications such as increased blood pressure and pulse which can lead to anxiety for the patient. The purpose of this study was to explain the effect of Progressive Muscle Relaxation (PMR) on anxiety, blood pressure and pulse in haemodialysis patients.Methods: The study design was a true pre-post-test control group design experiment. The total sample was 105 haemodialysis patients taken by purposive sampling technique and divided into two intervention groups and one control group. The independent variable was PMR, and the dependent variables were anxiety, blood pressure and pulse. Data were obtained using a questionnaire and analysed using the Kruskal Wallis Test and Mann-Whitney U test with a significance level <0.05.Results: The results of the PMR two times per week group analysis for one month showed a significant influence on anxiety (p=0.000), blood pressure (p=0.000), and pulse rate (p=0.000). Mann-Whitney U Test Results showed a significant effect on anxiety (p=0.004), blood pressure (p=0.000), and pulse (p=0.000).Conclusion: Haemodialysis patients who performed PMR interventions showed a promising outcome on a decrease in anxiety, blood pressure and pulse. The regular application of PMR interventions can control vital signs in patients undergoing haemodialysis
