Key result
Mean plasma BNP levels were highest in patients with systolic heart failure (934.6 pg/mL), followed by diastolic heart failure (181.8 pg/mL) and COPD (33.2 pg/mL), with no significant correlation to 6-minute walk distance (p=0.69).
Why the study?
Does plasma BNP concentration differentiate between systolic heart failure, diastolic heart failure, and chronic obstructive pulmonary disease in patients presenting with dyspnea?
Observational (n=57)
No
Does plasma BNP concentration differentiate between systolic heart failure, diastolic heart failure, and chronic obstructive pulmonary disease in patients presenting with dyspnea?
Plasma BNP levels can help differentiate the causes of dyspnea, with the highest levels seen in systolic heart failure compared to diastolic heart failure and COPD.
No takes yet. Share an insight, caveat, or question.
BNP levels may aid differentiation of dyspnea causes; leaves open prospective validation before clinical adoption.
Shin et al. (2003) conducted an observational in Dyspnea (n=57). Plasma BNP concentration vs. Systolic heart failure vs. diastolic heart failure vs. COPD was evaluated on Mean plasma BNP concentration at admission. Mean plasma BNP levels were highest in patients with systolic heart failure (934.6 pg/mL), followed by diastolic heart failure (181.8 pg/mL) and COPD (33.2 pg/mL), with no significant correlation to 6-minute walk distance (p=0.69).
