In this episode, we review the role of biomarkers and lab abnormalities in congestive heart failure. What are ANP, BNP, CNP, and DNP? What effect does BNP have on glomerular filtration rate, urinary sodium excretion, adrenal aldosterone secretion, and peripheral vascular tone? What is the relationship between BNP and NTproBNP? What are some factors that increase BNP and NTproBNP? What are some factors that decrease BNP and NTproBNP? How should NTproBNP thresholds be adjusted in older adults and patients with obesity? Why does hyponatremia occur in acute decompensated heart failure? Tune in for answers to these questions.
