Brief summary
CADKID-study is a prospective follow-up study assessing arterial disease, quality of life, mortality and their predictors in patients with severe chronic kidney disease.
Detailed description
Chronic kidney disease (CKD) is associated with increased risk of cardiovascular disease and mortality as well as impaired quality of life. Participants of this study all have severe CKD, defined as estimated glomerular filtration rate \< 30 ml/min per 1.73 m\^2. Stress ergometry, echocardiography, ultrasound assessment of arterial intima-media thickness, lateral lumbar radiograph, ECG, laboratory tests and quality of life assessment were performed at the baseline of the study and will be repeated during follow-up. Atrial fibrillation and other cardiac arrhythmias as well as pulse wave velocity measurements will be explored. Diet diaries are gathered and analysed. The aim of the study is to identify factors associated with cardiovascular disease, quality of life and mortality in this cohort.

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Rate of hospitalizations | 2 years, 5 years | — |
| Abdominal aortic calcification (AAC) score | 2 years, 5 years | Scale 0-24, higher values indicate more calcification |

| Changes in quality of life | 2 years, 5 years | Kidney Disease Quality of Life Short Form (KDQOL-SF) instrument, consisting of 20 subscales (0-100), higher score indicating better quality of life |
| Maximal bicycle stress ergometry performance | 2 years, 5 years | Mean work load (watts) of the last 4 minutes of exercise, higher values indicating better performance |
| Left ventricular hypertrophy | 2 years, 5 years | Echocardiography (Interventricular septum thickness, Posterior wall thickness, Left ventricular end-diastolic diameter, Left ventricular mass index) |
| Cardiac systolic function | 2 years, 5 years | Echocardiography (Left ventricular ejection fraction, Left ventricular global longitudinal strain) |
