Table.
Patients' characteristics in the derivation cohort for heart failure survival score (HFSS)11 and in the present cohort (COCPIT study). Values are means (SD) unless stated otherwise
| Characteristic | HFSS derivation cohort (n=268) | COCPIT cohort (n=889) |
|---|---|---|
| Age (years) | 50 (11) | 52 (11) |
| % male patients | 80 | 85 |
| New York Heart Association class | 2.8 (0.9) | 3.3 (0.5) |
| HFSS parameters: | ||
| Left ventricular ejection fraction (%) | 20 (8) | 22 (8) |
| Peak oxygen uptake (ml/min/kg) | 14.6 (5.4) | 15.8 (19.2)* |
| Heart rate (beats/min) | 87 (15) | 85 (17) |
| Mean arterial pressure (mm Hg) | 86 (13) | 82 (12) |
| Serum sodium concentration (mmol/l) | 137 (4) | 138 (5) |
| % of patients with intraventricular conduction delay | 27 | NK† |
| % of patients with ischaemic cardiomyopathy | 45 | 41 |
| Range of HFSS variability | 5.8-10.5 | 5.6-10.5 |
| Severity of heart failure (No (%) of patients): | ||
| High risk (HFSS⩽7.19) | 56 (21) | 107 (12) |
| Medium risk (HFSS=7.20-8.09) | 94 (35) | 360 (41) |
| Low risk (HFSS⩾8.10) | 118 (44) | 422 (47) |
HFSS=heart failure survival score.
COCPIT=comparative outcome and clinical profile in transplantation study.
NK=not known (since COCPIT study started before publication of the heart failure survival score, intraventricular conduction delay was not collected in our cohort).
