Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Application of Nanotechnology and Chemical Sensors for Diagnosis of Decompensated Heart Failure by Respiratory Samples.

Breath testing, which links specific volatile molecular biomarkers in exhaled breath to medical conditions, is becoming increasingly popular as a non-invasive and potentially inexpensive diagnostic method for various diseases. NA-NOSE performs odor detection from exhaled breath, thus producing a distinct fingerprint for each mixture of analytes.

Several studies have been published, stating the advantages of these sensors, leading to promising outcomes in several fields.

The NA-NOSE breath test would be fast (examination and results would be obtained within 5-10 min), inexpensive, eventually portable (smaller than desktop computer), non-invasive and free of any side effects.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Patients with compensated heart failure

Collection of breath samples, followed by analysis of exhaled breath using nanomaterial-based sensors (NaNose)

Intervention Type DIAGNOSTIC_TEST

2-3 liters of breath sample will be collected in chemically inert Mylar bags. The breath samples will then be immediately transferred from the Mylar bags to Tenax sorbent tubes using a dedicated pump. Tubes will be sealed and kept in 4˚C until NA-NOSE analysis.

Patients with decompensated heart failure

Collection of breath samples, followed by analysis of exhaled breath using nanomaterial-based sensors (NaNose)

Intervention Type DIAGNOSTIC_TEST

2-3 liters of breath sample will be collected in chemically inert Mylar bags. The breath samples will then be immediately transferred from the Mylar bags to Tenax sorbent tubes using a dedicated pump. Tubes will be sealed and kept in 4˚C until NA-NOSE analysis.

Healthy subjects

Collection of breath samples, followed by analysis of exhaled breath using nanomaterial-based sensors (NaNose)

Intervention Type DIAGNOSTIC_TEST

2-3 liters of breath sample will be collected in chemically inert Mylar bags. The breath samples will then be immediately transferred from the Mylar bags to Tenax sorbent tubes using a dedicated pump. Tubes will be sealed and kept in 4˚C until NA-NOSE analysis.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* signed informed consent
* ≥ 18 years of age, male or female
* Left ventricular Ejection fraction less than 40% or known to suffer from heart failure with preserved ejection fraction
* In decompensated heart failure group: dyspnea with confirmation of pulmonary congestion/edema by chest x-ray

Exclusion Criteria

* Pericardial diseases, e.g. constrictive pericarditis, tamponade
* Significant congenital heart disease, up to the investigator's opinion
* Life-threatening or uncontrolled arrhythmia, including symptomatic or sustained ventricular tachycardia and atrial fibrillation or flutter with a resting ventricular rate \>110 beats per minute.
* Acute ST elevation myocardial infarction
* Pregnant women
* Patients with pulmonary embolism
* Probable alternative diagnoses that in the opinion of the investigator could account for patient's HF symptoms (i.e., dyspnea), such as:

1. significant pulmonary disease
2. anemia with hemoglobin \<10 g/dl
* participation in another study
