Sauna Use Reduced Brain Natriuretic Peptide in Chronic Heart Failure Patients

by admin on March 9, 2011

Brain Natriuretic Peptide, or BNP for short, is a hormone that is produced by the heart and is often used as a marker for determining how well the heart is functioning. Thus, improvements in BNP is often seen as a sign that a patient’s condition is improving, especially when relief of other symptoms is present.

See below:

Clinical symptoms were improved in 17 of 20 patients after two weeks of sauna therapy. The %FMD after two-week sauna treatment significantly increased from the baseline value, whereas the %NTG-induced dilation did not. Concentrations of BNP after the two-week sauna treatment decreased significantly. In addition, there was a significant correlation between the change in %FMD and the percent improvement in BNP concentrations in the sauna-treated group. In contrast, none of the variables changed at the two-week interval in the nontreated group. (via.)

NTG is the dilation they detected in the brachial artery from the nitroglycerin, while the FMD is the dilation they detected from the sauna therapy.
