Table 1 The original 28 variables

From: Neural hypernetwork approach for pulmonary embolism diagnosis

1 ID Patient’s identifier
2 Age With the increase of the age, increase the incidence
3 N_F_Pred Number of predictive factors
4 N_F_Risk Number of risk factors
5 Previous DVT A previous DVT / PE is a risk factor repeated infringement DVT / PE
6 Palpitations Aspecific symptom. If it implies a tachycardia could be associated with DVT/PE
7 Cough Coughs symptom very nonspecific but frequently present in patients with DVT / PE
8 dDimer A value of d-Dimer <230ng = ml is associated with a low risk / absent of DVT/ PE. A very high value is associated with a high risk of DVT / PE
9 PAS A low PAS is present in patients with DVT / PE and hemodynamic shock
10 PAD In cardiogenic shock with DVT / PE is low, sometimes undetectable. By itself has no value despite of the PAS
11 FC In the patient with TVP / EP tachycardia is often found
12 PAPS It is one of the criteria of right ventricular dysfunction. It can be normal in the case of EP low entity.
13 WBC The value increases with inflammatory forms (pneumonia, etc...) that can be confused with DVT / PE
14 Cancer at diagnosis Cancer at diagnosis It is a risk factor for DVT / EP recognized
15 Troponin It is a marker of myocardial infarction or heart failure and can be confused with DVT / PE
16 Shockindex It is the ratio between PAS and FC, if it is greater than 1 is indicative of shock
17 NEOPLASIA It is a risk factor for DVT / EP recognized
18 RVD Right ventricular overload in the course of DVT / PE
19 Wells score Wells score
20 Revised Geneva score Revised Geneva
21 Wicki score Wicki’ score
22 Dyspnea Main symptom in DVT / PE
23 Chest pain Chest pain is present in myocardial infarction, in pleural effusion, in the high DVT
24 PCO2 Associated with low pO2 may be suggestive of DVT / PE
25 PO2 Associated with low pCO2 may be suggestive of DVT / PE
26 PH In DVT / EP pH is usually normal
27 Hemoptysis It is the expectoration (coughing up) of blood or of blood-stained sputum from the bronchi, larynx, trachea, or lungs
