Baseline and post-endoscopy human brain natriuretic peptide (hBNP) levels in patients aged <65 years and patients ≥65 years with and without cardiovascular disease. All data were expressed as mean ± SD. Analyses were conducted using Student's t test. In the ≥65 year age group with cardiovascular disease, hBNP level was significantly greater than at baseline (p<0.05).
