Multiple Fine and Gray competing risk model on first appropriate in ICD patients stratified by region including ECG parameters of interest (n = 1465)
| HR | 95% CI | P-value | |
|---|---|---|---|
| Digitalis glycoside (yes vs. no) | 2.56 | 1.50–4.37 | <0.01 |
| BMI (kg/m2) | 1.04 | 1.01–1.08 | <0.01 |
| Sex (male vs. female) | 2.47 | 1.25–4.88 | <0.01 |
| Chronic obstructive pulmonary disease (yes vs. no) | 1.75 | 1.06–2.90 | 0.03 |
| Including single parameters into the model above leads to the following results | |||
| QTc (ms) | 1.01 | 1.00–1.01 | 0.02 |
| Atrial fibrillation (yes vs. no) | 1.50 | 0.97–2.31 | 0.07 |
| Sinus rhythm (yes vs. no) | 0.67 | 0.39–1.17 | 0.16 |
n = 1465, statistically significant results presented in bold.
95% CI, 95% confidence interval; BMI, body mass index; ECG, electrocardiogram; HR, hazard ratio; ICD, implantable cardioverter-defibrillator; QTc, QT-interval corrected by Framingham’s formula.
