title: Heart-type Fatty Acid Binding Protein in the Assessment of Acute Pulmonary Embolism.
abstract: OBJECTIVE
  To explore the predictive value of heart-type fatty acid binding protein (H-FABP) in the stratification and prognosis of patients with acute pulmonary embolism (APE).
  
  
  METHODS
  According to risk stratification, 69 patients with APE admitted into the emergency department within 24 hours after onset were divided into the following 3 groups: high-risk group, moderate-risk group and low-risk group. H-FABP- and cardiac troponin I (cTNI)-positive rates of all groups were analyzed and compared, and the correlation between major adverse events (death, endotracheal intubation and cardiopulmonary resuscitation) and the cardiac markers (heart rate, arterial partial pressure of oxygen, right ventricular dimension, pulmonary arterial pressure, etc.) during the in-hospital period were statistically analyzed. Then the prognosis (death, embolic pulmonary hypertension, right heart failure and recurrence of APE) at 6 months after onset of APE was followed-up on and compared between groups.
  
  
  RESULTS
  The admission time of high-risk group patients was earlier than non-high-risk group (7.1 ± 2.9 versus 13.5 ± 6.7 versus 15.2 ± 10.7 hours, P = 0.001), had larger right ventricular dimension (33.1 ± 10.4 versus 26.7 ± 7.3 versus 20.5 ± 8.9mm, P = 0.002) and higher pulmonary arterial pressure (45.8 ± 14.6 versus 29.4 ± 13.9 versus 23.1 ± 12.6mmHg, P = 0.001). The major adverse events during in-hospital period, including death, endotracheal intubation and cardiopulmonary resuscitation, were more prevalent in the high-risk group than those in the other 2 risk groups. Further analysis indicated that the positive rate of H-FABP was remarkably higher than cTNI (52/69, 75.4% versus 28/69, 40.6%, P = 0.003). The H-FABP (r = 0.881, P = 0.020) was significantly correlated to the major adverse events; however, this was not so regarding cTNI (r = 0.115, P = 0.059). At 6 months after onset of APE, the follow-up data indicated that cTNI and H-FABP were both significantly correlated with the major adverse events.
  
  
  CONCLUSIONS
  The positive rate of H-FABP was higher than cTNI during the 24 hours after the onset of APE. The H-FABP was significantly correlated to the major adverse events during hospitalization and to the primary prognosis at 6 months after onset of APE.
