The brain natriuretic peptides (BNP, NT-proBNP) are useful diagnostic markers of heart failure (HF), as exemplified by the ESC Heart Failure guidelines. The PolSenior project was an epidemiological study carried out to examine medical, psychological and socioeconomic aspects of aging in Poland. The aim of this study is an epidemiological description of HF based on elderly population from the PolSenior Study, stratified by NT-pro-BNP concentration values.

Material and methods:

The research sample included 4979 respondents (2567 males and 2412 females) split into six equally sized age groups of elderly individuals. The study consisted of three visits performed by trained nurses and included a questionnaire survey, comprehensive geriatric assessment and blood and urine sampling with more than 50 biochemical parameters measured. Serum NT-pro-BNP was measured by electrochemiluminescence method (ECLIA).


The prevalence of chronic kidney disease (CKD) (77.8%) and atrial fibrillation (39.5%), number of hospitalizations (23.7%) and number of patients treated with HF drugs were highest in NT-proBNP >2000 pg/ml group and least frequent in NT-proBNP <400 pg/ml group. Obese patients had significantly more frequently NT-proBNP values <400 pg/ml (73.0%) and less frequently NT-proBNP values >2000 pg/ml (2.8%). Age over 70 years and male gender were associated with the increased NT-pro-BNP (>400 pg/ml) (OR 1.41; CI 1.20–1.65 for male gender).


We conclude that CKD and atrial fibrillation are associated with the occurrence of increased NT-pro-BNP, the surrogate for HF in elderly population. On the contrary, overweight or obesity is associated with lower prevalence of HF in elderly.
