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 |
28 | Final diagnose | Final physicians’ diagnosis |
