CD40LG and Hypertension: We considered monocytes (OR: 1.04; 95% CI: 1.00–1.09; P = .051), serum creatinine (OR: 1.02; 95% CI: 1.00–1.02; P = .042), sCD40L (OR: 1.07; 95% CI: 1.00–1.14; P = .033), and a history of hypertension (OR: 1.30; 95% CI: 1.01–1.58; P = .048) as independent risk factors for readmission in patients with chronic HF (Table 4).
