ALB and heart failure: A bivariate logistic analysis was performed to analyze the predictors of thrombosis in COVID-19 patients; P/F ratio < 200 (OR 1.718, 95% CI 1.085–2.718, p = 0.021), albumin (OR 1.693, 95% CI 1.055–2.716, p = 0.029), D-dimer (OR 3.469, 95% CI 2.110–5.703, p < 0.0001), CAD (OR 1.800, 95% CI 1.086–2.984, p = 0.023) and heart failure (OR 2410, 95% CI 1.385–4.193, p = 0.002) independently predicted thrombotic events in this population (see Table 3).
