Effects of implantation strategy on mode of death
| Death from pump failure | Sudden cardiac death | |||||
|---|---|---|---|---|---|---|
| HR (95% CI) * | χ2 | p | HR (95% CI) * | χ2 | p | |
| +CMR+S | 5.40 (2.92 to 9.94) | 29.1 | < 0.0001 | 4.40 (1.24 to 15.62) | 5.26 | 0.0218 |
| -CMR | 1.12 (0.67 to 1.85) | 0.13 | 0.6847 | 2.93 (1.11 to 7.76) | 4.71 | 0.0299 |
*, Hazard ratios (HR) and 95% confidence intervals (CI) refer to the risk of meeting the endpoints in comparison to the group in which CMR was performed and the LV lead was deployed in non-scarred myocardium. Adjustment has been made for age, NYHA class, QRS duration, history of CABG and of chronic atrial fibrillation in Cox proportional hazards analyses. +CMR+S = CMR showing scar at the LV pacing position; -CMR = non-CMR guided group.
