NPPB and chronic kidney disease: Participants who did not receive beta-blocker prescription were significantly older (mean age 77.45 ± 8.93 versus 73.92 ± 8.87, p = 0.007), had higher prevalence of chronic kidney disease (36.5% versus 15.2%, p < 0.001), chronic obstructive pulmonary disease (12.9% versus 1.9%, p = 0.003), and had higher levels of NTproBNP (7248.76 ± 9730.11 versus 3669.45 ± 5113.77 pg/mL, p = 0.003) and serum creatinine (144.37 ± 59.13 versus 118.15 ± 60.84 mcmol/l, p = 0.003) compared to participants who were prescribed beta-blockers (Table 1).
