4 cze 2024 · A higher dialysate flow rate (800 ml/min) increased single-pool Kt/V by 0.08 [95% confidence interval (CI) 0.05–0.10, P < .00001] and URR by 3.38 (95% CI 1.97–4.78, P < .00001) compared with a dialysate flow rate of 500 ml/min. Clinically relevant outcomes including symptoms, cognition, physical function and mortality were lacking and ...
29 kwi 2024 · Blood flow rate (BFR) is a key determinant of dialysis adequacy under the condition of three times per week for 4 h for each hemodialysis (HD) session [Citation 1]. An increased BFR can significantly improve single-pool Kt/V (spKt/V) and may improve survival in maintenance hemodialysis (MHD) patients [Citation 2, Citation 3].
4 sie 2016 · Patients on hemodialysis with an LVEF ≤40% or those with new symptoms of concern regarding ischemic heart disease are recommended to be evaluated continuously for CAD. 23, 24
Chronic hemodialysis patients manifest acute cardiovascular complications such as intradialytic hypotension, intradialytic hypertension, arrhythmias, acute coronary syndromes and sudden death. Thus, proper management is extremely important.
This review article focuses on the specific cardiovascular hemodynamics of dialysis patients and how it is affected by the AV access; the effects of an excessive increase in AV access flow, leading to high-output heart failure; congestive heart failure in CKD patients and the contraindications to AV access; pulmonary hypertension.
2 sie 2009 · In conjunction with this, HD patients are particularly susceptible to myocardial ischemia. This is as a result of large vessel and microcirculatory changes resulting in a reduced coronary flow reserve. This determines the ability to increase blood flow to the myocardium during increased demand.
Cardiovascular disease is the principal cause of morbidity and mortality in dialysis patients. The principal alterations responsible are left ventricular hypertrophy and arterial disease characterized by an enlargement and hypertrophy of arteries and the high prevalence of atheromatous plaques.
