  1. Results are presented as number (percentage), mean ± standard deviation, or median (interquartile range). eGFR, estimated glomerular filtration rate; N, number of patients with available data; CAD, coronary artery disease; CHF, congestive heart failure; COPD, chronic obstructive lung disease; PE, pulmonary embolism (acute or chronic); ACEI, angiotensin converting enzyme inhibitor; ARB, angiotensin receptor blocker; A1: albuminuria < 30 mg/g of creatinine; A2: albuminuria 30–300 mg/g of creatinine; A3: albuminuria > 300 mg/g of creatinine; Hb, hemoglobin; K+, potassium; Phos, phosphorus; BNP, brain natriuretic peptide. Percentages are within eGFR group and exclude missing values. The three eGFR groups were statistically different (P value for trend < 0.001 for all parameters except sex)
