Levels of Plasma N-terminal Pro-brain Natriuretic Peptide and D‑dimer on the Prognosis of Patients with Acute Cerebral Infarction

Objective: To investigate the effects of levels of D-dimer and N-terminal pro-brain natriuretic peptide (NT-pro BNP) on the prognosis of patients with acute cerebral infarction.

Methods: One hundred and twenty-four patients with acute cerebral infarction who were admitted to the hospital between July 2014 and July 2016 were selected as the observation group; 100 normal people who had health examination in the center of physical examination of our hospital were selected as the control group. The levels of D-dimer and NT-pro BNP of the two groups were observed; the correlation between the levels of plasma NT-pro BNP and D-dimer and area of cerebral infarction, complications and death condition of the observation group was investigated.

Results: The levels of D-dimer and NT-pro BNP of the observation group were much higher than those of the control group, and the difference was statistically significant (P<0.05). The levels of D-dimer and NT-pro BNP of the observation group were significantly higher than those of the control group, and the difference had statistical significance (P<0.05). The levels of plasma NT-pro BNP and D-dimer of the patients with disturbance of consciousness and high blood pressure were apparently higher than those with no disturbance of consciousness and normal blood pressure, and there was a statistically significant difference (P<0.05). The patients were followed up for half a year. The levels of D-dimer and NT-pro BNP of the dead patients were much higher than those of the survived patients on admission.

Conclusion: The levels of plasma NT-pro BNP and D-dimer can reflect the disease condition and prognosis of patients with acute cerebral infarction. Higher levels of NT-pro BNP and D-dimer indicates poorer prognosis. This work can provide a guidance for the clinical treatment of acute cerebral infarction.
