An analysis of the exhaled air by means of an "electronic nose" to distinguish people with heart disease in healthy allows. Within the group of patients can be assessed by this method, for example, the severity of myocardial disease. This shows a recent study by the Munich-based research group that in 79. Annual Meeting of the German Cardiac Society (DGK) was presented in Mannheim. "This method allows us, in principle, to differentiate between healthy and sick people and within the patients by severity. Whether and to what extent this approach, the clinical evaluation, for example in the detection of clinical comorbidities support, needs to be clarified in further prospective studies of large independent groups of patients, "said Dr. Uta Ochmann from Munich University Hospital.
"Electronic noses" (enose) are used to identify patterns of chemical compounds in the exhaled air and to recognize in this way diseases or to differentiate between them. In the Munich study found an electronic nose used, in which the breathing air is analyzed by 32 polymer sensors based on metal.
"Volatile organic components" (VOCs) are measured in the breathing air. VOCs are biomarkers in exhaled air, the composition of which can change in heart disease. 56 patients with myocardial diseases, heart diseases due to high blood pressure or acute myocardial infarction as well as 43 healthy subjects were examined.
