Abstract:Objective To investigate the effect of serum transaminase on the survival of patients with acute coronary syndrome after PCI. Methods Totally 315 patients with coronary heart disease (CHD) who underwent PCI in our hospital from April 2013 to January 2017 were selected as the subjects. A total of 45 dead patients were in the death group and other 270 cases were in control group. Several follow-up assessments were performed with retrospective analysis. Results Compared with the control group, age, heart rate, systolic blood pressure, diastolic blood pressure and body weight were statistically significant in death group (P < 0.05). There was no significant difference in the level of total cholesterol and triglyceride between the two groups (P > 0.05). Compared with the death group, albumin, hemoglobin, urea, creatinine, uric acid, C reactive protein, creatine kinase-MB, gamma glutamyl transpeptidase, alanine aminotransferase and aspartate aminotransferase levels were statistically significant in control group (P < 0.05). Age, heart rate, urea, creatinine, uric acid, C reactive protein, creatine kinase-MB, patients with gamma glutamyl transpeptidase, alanine aminotransferase, aspartate aminotransferase levels were positively correlated with death, while were negatively correlated with albumin and hemoglobin. Conclusions Elevation of serum transaminase is one of the factors that affects the survival status of PCI patients, which indicates a higher mortality rate.
