ObjectiveTo evaluate the prognosis factors for early death (within 60 days) of acute myocardial infarction (AMI) patients for early identification and prevention of the disease.
MethodsWe analyzed the information of AML patients who were admitted to the emergency department between May 2009 and July 2010, and analyzed their clinical data, such as gender, age, prehospital time, myocardial enzyme, electrocardiogram, complications, whether the patients had thrombolysis therapy, time of thrombolysis, end point observation and time of death, ect. Cox multivariate survival analysis was performed with the use of SPSS 18.0 software.
ResultsSeventy-one cases were collected with one of them excluded for fragmented data. After analysing, we found that patients' age and isoenzymes of creatine kinase (CK-MB) level were prognosis factors for early death. Further analysis showed that the relative risk (RR) of age was 1.166 (P=0.023), and the RR of CK-MB was 1.001 (P=0.004).
ConclusionPatients' age has predictive value for early death of AML. More attention should be paid to AML patients with advanced age. Detecting myocardial enzymes levels, especially the CK-MB level, is significant for predicting early death. Other indicators need to be further explored due to the possible limitation of our study.
