Table 3.

COVID-19 clinical severity for patients with recurrent AF compared to prior AF without prior AF during infection (propensity score matched*).

COVID-19 CLINICAL SEVERITY	Recurrent AF n = 394	Prior AF** n = 394	Odds Ratio (95% CI), p-value
Hospitalization	304 (77.2%)	156 (39.6%)	5.15 (3.78, 7.03), p < 0.0001
ICU	142 (36.0%)	50 (12.7%)	3.88 (2.70, 5.56), p < 0.0001
Oxygen	237 (60.2%)	142 (36.0%)	2.68 (2.01, 3.57), p < 0.0001
Ventilator Used	78 (19.8%)	24 (6.1%)	3.81 (2.35, 6.16), p < 0.0001

*Propensity Score Matched (score based on age, gender, race, ethnicity, prior CAD, prior heart failure, prior stroke and hypertension).

**Prior AF with no recurrent AF within a month of COVID-19 infection.

NOTE: AF = Atrial fibrillation, ICU = Intensive care unit, CI = confidence interval. Odds ratios and p-values are from logistic regression.
