Coronary Computed Tomography Angiography Results in Propensity Score–Matched Cohorts of 112 Dialysis Patients and 112 Without Chronic Kidney Disease
| Dialysis (n = 112) | Non-CKD (n = 112) | Pa | |
|---|---|---|---|
| Interpretable scansb | 111 (99%) | 112 (100%) | 0.99 |
| With CABG | 3 (3%) | 8 (7%) | 0.22 |
| With coronary stent | 7 (6%) | 51 (46%) | <0.001 |
| Without any lesions | 18 (16%) | 19 (17%) | 0.99 |
| Per patienta | |||
| No. of coronary segments | 14.0 ± 1.2 | 14.4 ± 1.0 | 0.03 |
| Total no. of lesions | 11.3 ± 8.6 | 10.5 ± 8.9 | 0.49 |
| No. of noncalcified lesions | 0.5 ± 1.0 | 2.4 ± 3.6 | <0.001 |
| No. of partially calcified lesions | 5.8 ± 5.2 | 5.1 ± 5.5 | 0.18 |
| No. of calcified lesions | 5.0 ± 5.7 | 3.1 ± 4.0 | 0.01 |
Note: Results are presented as mean ±standard deviation or number (percent).
Abbreviations and Definitions: CABG, coronary artery bypass grafting; Non-CKD, non–chronic kidney disease at risk for cardiovascular disease.
a
Significance tested with χ2 tests for proportions and Mann-Whitney U tests for number of lesions.
b
In 1 patient, computed tomography angiography could not be interpreted reliably (see text).
