Subgroup analysis on MESA cohort data using the ECG-AI-Cox model
| Subgroup | AUC (95% CI) |
|---|---|
| Sex | |
| Male | 0.83 (0.80–0.85) |
| Female | 0.84 (0.81–0.87) |
| Race/ethnicity | |
| White | 0.84 (0.82–0.87) |
| African American | 0.81 (0.79–0.85) |
| Chinese American | 0.85 (0.75–0.93) |
| Hispanic ethnicity | |
| No | 0.83 (0.81–0.85) |
| Yes | 0.87 (0.83–0.89) |
| Has any HF risk factor† | |
| Yes | 0.81 (0.79–0.83) |
| No | 0.77 (0.66–0.91) |
| HF type | |
| HFrEF | 0.85 (0.82–0.87) |
| HFpEF | 0.83 (0.80–0.85) |
| HF with missing EF | 0.87 (0.82–0.92) |
AUC = area under the receiver operating characteristic curve; EF = ejection fraction; HF = heart failure; HFpEF = heart failure with preserved ejection fraction; HFrEF = heart failure with reduced ejection fraction.
†
No HF risk factor category was defined as participants who did not have any of the following risk factors or clinical conditions: smoking, coronary heart disease, diabetes, hypertension, left ventricular hypertrophy, and valvular disease.
