[In-hospital effect of primary percutaneous coronary intervention on aged patients with acute myocardial infarction and diabetes mellitus].
OBJECTIVE
To evaluate the in-hospital effect of emergency percutaneous coronary intervention (PCI) on aged patients with acute myocardial infarction (AMI) and diabetes mellitus.


METHODS
The clinical data of 556 patients aged > or = 60 with AMI hospitalized from December 1995 to April 2005, who underwent emergency PCI within 24 hours after the onset, including 127 cases complicated with diabetes mellitus (Group DM) and 429 cases without diabetes (non-diabetes mellitus group, Group ND), were analyzed respectively.


RESULTS
There were not significant differences in age, sex, smoking rate, hypertension rate, myocardial infarction (MI) rate, and time between onset and treatment between these 2 groups. However, the percentages of anterior wall AMI rate, non-ST elevation myocardial infarction, Killip III-IV grade, and intra-aortic balloon pump (IABP) application of Group DM were 58.3%, 13.4%, 27.6%, and 16.5%, all significantly higher than those of Group ND (46.4%, 6.8%, 27.6%, and 8.6%, P < 0.001, 0.02, 0.03, and 0.01). In Group DM, 59.1% of the infarction related artery was left anterior descending branch, and in Group ND 45.0% of the infarction related artery was left anterior descending branch (P < 0.05). The rate of triple vessel disease in Group DM was 77.2%, significantly higher than that of the Group ND (60.8%, P < 0.01). There were no significant differences in the PCI immediate success rate, intra-operational no-reflow rate, post-PCI complication rate and mortality during hospitalization between the two groups.


CONCLUSIONS
Emergency in-hospital PCI is effective on aged AMI patients with diabetes mellitus.
