NON-INVASIVE METHOD FOR DIAGNOSING THE SEVERITY OF HEART FAILURE, USE OF A BIOMARKER FOR DIAGNOSING DECOMPENSATED HEART FAILURE, COLLECTOR DEVICE FOR THE HEART FAILURE BIOMARKER FROM EXHALED BREATH AND A DIAGNOSIS KIT

The invention application presents a fast, efficient, reproductive alternative of a non-invasive method for diagnosing the severity of heart failure based on a specific biomarker. An additional object of the present inven- tion is a collector device for the biomarker from exhaled breath that is portable, simple, low cost and does not need to run on electric power. This invention advantageously permits the replacement of invasive diagnosis methods, favoring the patient's comfort in addition to the agility and speed of medical attention at hospitals, and may become a standard method for all suspected cases of circulatory disease and heart failure and, more specifically, decompensated heart failure.
