Association between risk factors and self-report of cardiac-related PASC symptoms
| Risk factors | Cardiac-related PASC at enrolment | |
| OR (95% CI) | aOR (95% CI) | |
| Pre-existing CV risk factors/CVD* | ||
| No underlying CV risk factors/CVD (ref.) | 1.00 | 1.00 |
| Presence of underlying CV risk factors/CVD | 2.18 (1.44 to 3.31) | 2.01 (1.27 to 3.17) |
| Pre-existing conditions† | ||
| No pre-existing conditions (ref.) | 1.00 | 1.00 |
| Pre-existing conditions | 2.17 (1.48 to 3.20) | 2.00 (1.28 to 3.10) |
| Age (per year) | 1.02 (1.01 to 1.03) | 1.02 (1.01 to 1.03) |
| COVID-19 hospitalisation | ||
| Not hospitalised for COVID-19 (ref.) | 1.00 | 1.00 |
| Hospitalised for COVID-19 | 3.69 (1.96 to 6.97) | 3.03 (1.58 to 5.83) |
Crude and adjusted ORs and 95% CI were estimated using multivariable logistic regression models.
Stepwise, final model: income, race, education, days since positive test. Bold indicates statistically significant values, p< 0.05.
*CV risk factors included hypertension and dyslipidaemia; CVD included coronary artery disease, heart failure, atrial fibrillation, chronic ischaemic heart diseases, myocardial infarction, valvular heart disease, etc.
†Pre-existing conditions prior to COVID-19 infection (cardiovascular diseases, asthma, cancer, kidney disease, irritable bowel syndrome, etc).
aOR, adjusted odds ratio; CV, cardiovascular; CVD, cardiovascular disease; PASC, postacute sequelae of SARS-CoV-2 infection; ref., reference group.
