Abstract:
Objective To investigate the clinical significance of the combination detection of blood lactic acid,B-type brain natri-uretic peptide(BNP)and homocysteine(Hcy)in elderly acute cerebral infarction.Methods The arterial and venous blood during a-cute onset stage,at 24,48,72 h after thrombolysis and at 12 h after fasting in 85 cases of acute cerebral infarction was collected for detecting blood lactic acid,BNP and Hcy,performing the dynamic monitoring analysis and the comparative observation with the healthy control group.Results The blood lactic acid,BNP and Hcy levels in the acute onset stage group and the recovery group were significantly increased compared with the healthy control group(P <0.05).The blood lactic acid,BNP and Hcy levels during the onset stage in the acute cerebral infarction group were(6.47 ±3.92)mmol/L,(100.52 ±48.96 )pg/mL and(48.96 ±15.13 )μmol/L respectively,which were significantly higher than those at 48,72 h of postoperative recovery,the differences between them were statistically significant(P <0.05).The blood lactic acid,BNP and Hcy levels during postoperative convalescence in the cere-bral infarction group were gradually decreased and declined to the minimal level until postoperative 72 h,which were(2.16±1.83) mmol/L,(33.61±10.42)pg/mL and(18.87±8.27)μmol/L respectively.Conclusion Blood lactic acid,BNP and Hcy are closely related with the occurrence and development of cerebral infarction,the joint detection of these three indicators provide a reliable ba-sis for the early diagnosis of elderly acute cerebral infarction.The active and effective treatment on the patient should be timely a-dopted and the dynamic monitoring should be performed in order to correctly assess the prognosis.
