Brain natriuretic peptide detects cardiac abnormalities in mass screening

Area of Science:

• Cardiology
• Biomarkers
• Preventive Medicine

Background:

• Elevated plasma brain natriuretic peptide (BNP) is linked to asymptomatic cardiac abnormalities.
• Conventional health check-ups may miss these subtle cardiac conditions.

Purpose of the Study:

• To evaluate the utility of plasma BNP measurement in identifying asymptomatic cardiac abnormalities.
• To assess BNP's role in enhancing mass screening for cardiovascular disease.

Main Methods:

• 4818 subjects without detected cardiac abnormalities underwent plasma BNP measurement.
• Echocardiography was performed on a subset of subjects with elevated BNP levels.

Main Results:

• 925 out of 4818 subjects had elevated plasma BNP concentrations.
• Echocardiography revealed various cardiac abnormalities in 174 subjects, including valvular heart disease and ventricular dysfunction.

Conclusions:

• Plasma BNP measurement is valuable for detecting asymptomatic cardiac abnormalities in seemingly healthy individuals.
• BNP testing is suitable for high-quality mass screening programs to improve cardiovascular health detection.
