HR of out-of-hospital cardiac arrest (OHCA) in patients with long-term stress conditions or anxiety: stratification according to age
| Cases (n=35.195) | Controls (n=351.950) | Crude HR (95% CI) | Adjusted HR (95% CI) | |
| Age ≤65 years | 11.444 | 114.440 | ||
| Neither of the two diagnoses | 11.071 (96.74%%) | 112.930 (98.68%) | reference | reference |
| Long-term stress | 209 (1.83%) | 873 (0.76%) | 2.45 (2.10 to 2.85) | 1.51 (1.27 to 1.79) |
| Anxiety | 135 (1.18%) | 554 (0.48%) | 2.50 (2.07 to 3.02) | 1.42 (1.15 to 1.75) |
| Both diagnoses | 29 (0.25%) | 83 (0.07%) | 3.60 (2.36 to 5.50) | 1.72 (1.07 to 2.75) |
| Age >65 years | 23.751 | 237.510 | ||
| Neither of the two diagnoses | 23.460 (98.77%) | 236.007 (99.37%) | reference | reference |
| Long-term stress | 115 (0.48%) | 704 (0.30%) | 1.64 (1.35 to 2.00) | 1.09 (0.89 to 1.35) |
| Anxiety | 164 (0.69 %) | 744 (0.31%) | 2.22 (1.87 to 2.63) | 1.51 (1.26 to 1.81) |
| Both diagnoses | 12 (0.05%) | 55 (0.02%) | 2.20 (1.18 to 4.11) | 1.56 (0.81 to 3.02) |
Numbers in table are number (%) unless indicated otherwise. HR adjusted for presence of cardiovascular disease, depression and the use of QT-prolonging drugs.
P value interaction: long-term stress=0.0639, anxiety=0.5647, both diagnoses=0.6069.
