Multivariate analysis of issues identified at the different baseline QoL elements in the prediction of clinical response, reverse remodelling, and mortality following CRT
| OR | 95% CI | χ2 | P-value | |
|---|---|---|---|---|
| Clinical response | ||||
| Mobility | 0.36 | 0.16–0.84 | 5.62 | 0.01 |
| Echo responder | ||||
| Self-care | 0.10 | 0.01–0.94 | 4.06 | 0.04 |
| Mortality at 5 years | HR | 95% CI | χ2 | P-value |
| Self-care | 2.39 | 1.17–4.86 | 5.78 | 0.01 |
| Anxiety/depression | 1.51 | 1.00–2.26 | 3.93 | 0.04 |
Hazard ratios refer to 1 SD increase. Clinical responder model was adjusted for LVEF and ischaemic HF; echocardiographic responder model was adjusted for age, NYHA, and LVEDV; and mortality at 5 years was adjusted for LBBB, presence of AF, BB, and diuretics intake.
CI, confidence interval; HR, hazard ratio; OR, odds ratio; χ2: Wald chi square.
P value lower than 0.05 was considered statistically significant.
