Risk of SAHRE According to the C2HEST Score Groups
| C2HEST Score | Patients, n (%) | SAHRE, n | Incident Rate* (95% CI) | HR (95% CI) | P Value |
|---|---|---|---|---|---|
| 0 or 1 | 144 (28.5) | 5 | 0.85 (0.27–1.94) | Reference | Reference |
| 2 or 3 | 211 (42.2) | 17 | 1.87 (1.06–2.91) | 2.06 (0.76–5.59) | 0.159 |
| ≥4 | 145 (29.0) | 22 | 3.62 (2.14–5.16) | 4.25 (1.61–11.22) | 0.004 |
C2HEST indicates coronary artery disease or chronic obstructive pulmonary disease (1 point each), hypertension (1 point), elderly (age ≥75 years, 2 points), systolic heart failure (2 points), thyroid disease (1 point); HR, hazard ratio; and SAHRE, sustained atrial high‐rate episode.
