For this reason, aiming to enhance the specificity of predicting the value of the risk of cardiovascular events, we categorized COVID-19 patients into high- and low-NT-proBNP groups using the upper quartile of NT-proBNP as a threshold and divided patients into normal and elevated cTnT groups using the 99th percentile upper reference limit as the threshold of cTnT. Here, NPPB is linked to COVID-19.
