Intracranial hemorrhage is common after intravenous thrombolysis (IVT) in acute ischemic stroke. Increasing studies have focused on risk and predictive factors for hemorrhagic transformation (HT).
To understand the pathogenesis of HT and provide interventions that may help to increase the safety of IVT.
This study aimed to investigate the relationship of serum calcium, albumin, globulin and matrix metalloproteinase-9 (MMP-9) levels and HT after IVT.
The study investigated patients receiving recombinant tissue plasminogen activator (rt-PA) for acute cerebral infarction. Demographic, clinical and laboratory information, HT and functional outcomes were compared between patients with HT and those without HT.
The study demonstrates that serum calcium and albumin levels were decreased in the HT group compared with the non-HT group and globulin and MMP-9 levels were increased in the HT group. This indicates that the low serum calcium and albumin levels and high globulin and MMP-9 levels are associated with the occurrence of HT following IVT in patients with cerebral infarction.
National Institutes of Health stroke scale score, serum calcium, albumin, globulins and MMP-9 were independent factors influencing the occurrence of HT in patients with cerebral infarction treated with IVT-rt-PA.
Further studies investigating additional potential factors are needed to confirm these results in patients treated with IVT-rt-PA to decrease the occurrence HT after IV rt-PA.
