Show moreRationale The impact of prophylactic implantable cardioverter-defibrillator (ICD) implantation on the psychological well-being of patients on dialysis is unknown.Objective We aimed to identify the effect of primary ICD implantation on quality of life (QoL), mood and dispositional optimism in patients undergoing dialysis.Methods and results We performed a prespecified subanalysis of the randomized controlled ICD2 trial. In total, 177 patients on chronic dialysis, with an age of 55-81 years, and a left ventricular ejection fraction of >= 35%, were included in the per-protocol analysis. Eighty patients received an ICD for primary prevention, and 91 patients received standard care. The Short Form-36 (SF-36), Geriatric Depression Scale-15 (GDS-15), Revised Life Orientation Test (LOT-R) questionnaires were administered prior to ICD implantation (T0), and at 1-year follow-up (T1) to assess QoL, depression and optimism, respectively. The patients were predominantly male (76.0%), with a median age of 67 years. Hemodialysis was the predominant mode of dialysis (70.2%). The GDS-15 score difference (T1 - T0) was 0.5 (2.1) in the ICD group compared with 0.3 (2.2) in the control group (mean difference - 0.3; 95% CI - 1.1 to 0.6; P = 0.58). The LOT-R score difference was - 0.2 (4.1) in the ICD group compared with - 1.5 (4.0) in the control group (mean difference - 1.1 (0.8); 95% CI - 2.6 to 0.4; P = 0.17). The mean difference scores of all subscales of the SF-36 were not significantly different between randomization groups.Conclusions In our population of patients on dialysis, ICD implantation did not affect QoL, mood or dispositional optimism significantly during 1-year follow-up.

Show moreChronic kidney disease (CKD) is a worldwide growing epidemic associated with an increased risk of cardiovascular morbidity and mortality. Heart failure is particularly frequent among patients with CKD. Pressure and volume overload and non-hemodynamic factors associated with CKD induce left ventricular (LV) hypertrophy, reduce capillary density and increase myocardial fibrosis that lead to LV diastolic and systolic dysfunction. These processes have been proposed as important determinants of increased mortality in this population. The aim of this thesis was to evaluate cardiac mechanics using two-dimensional (speckle tracking) echocardiography and coronary computed tomography angiography in patients with CKD to define the prevalence and prognostic implications of cardiovascular diseases. In pre-dialysis and dialysis patients with preserved LV ejection fraction (LVEF), assessment of left ventricular global longitudinal strain (LV GLS) helps to identify patients with higher rates of heart failure hospitalization and all-cause mortality. When LVEF has already declined, patients within the lowest quartile of LV GLS showed worse prognosis compared to the other groups. The burden of cardiovascular diseases in patients with CKD is high and thorough assessment of cardiac mechanics with (advanced) echocardiographic techniques and coronary CTA helps in identifying patients with worse prognosis, who would potentially benefit of early treatment.
