Abstract Objective To investigate the electrocardiogram(ECG) features and clinical manifestations of diabetics with painless acute myocardial infarction(AMI). Methods Two hundred and sixtytwo diabetics with AMI were selected, and divided into chest painless group(113 cases, group A) and pain group(149 cases, group B) separately. The clinical data and ECGs of the two groups were comparatively analyzed. Results In group A, infarcts were mainly observed in inferior wall, and the locations of ST-segment elevation and infarct were more than those in group B. In group B, the majority of infarcts occurred in front wall. The differences between the two groups were statistically significant(P<0.05). The incidences of chest pain, palpitation and syncope in group A were lower than those in group B, with statistically significant differences(P<0.05). The incidences of shortness of breath, toothache and nausea in group A were higher than those in group B, with statistically significant difference(P<0.05). The fatality rate of group A was higher than that of group B, with statistically significant differences(P<0.05). ConclusionFor the uncharacteristic clinical symptoms of diabetes complicating painless AMI in elderly people, the visiting time is prone to be postponed, partly resulting in high fatality rate. Clinicians should raise the understanding of diabetes complicating painless AMI, in order to reduce mortality and increase cure rate.
