[Angiographic characteristics and long term clinical outcomes post coronary stenting in non-diabetic and type 2 diabetic patients with coronary artery disease].
OBJECTIVE
To observe the angiographic characteristics and the long-term clinical outcomes following coronary stenting in non-diabetic (non-DM) and type 2 diabetic (DM) patients with coronary artery disease.


METHODS
This cohort study enrolled 1172 consecutive patients with coronary heart disease underwent elective coronary stenting (249 type 2 DM and 923 non-DM). The angiographic characteristics and the long-term clinical follow-up results were compared between non-DM and DM patients.


RESULTS
The follow-up period was (39.2 +/- 6.4) months (6 - 83 months), follow-up rate was 90.3% in DM and 91.0% in non-DM group (P > 0.05). Compared with non-diabetic patients, there were significantly higher incidences of 2-vessel (P = 0.029) and 3-vessel (P = 0.013) diseases of coronary artery, severe stenosis lesion (P = 0.012), chronic total obstructive lesion (P = 0.044) and long lesion (P = 0.001), in-stent restenosis (ISR, P = 0.000) and revascularization (P = 0.000) and MACE (P = 0.000) in DM patients. COX multiple factorial analysis showed that DM is independent risk factor for ISR (P = 0.000), revascularization (P = 0.001) and MACE (P = 0.003).


CONCLUSIONS
CHD patients with type 2 DM are associated with multi- and more severe vessel lesions. Type 2 DM is also an independent risk factor for increased ISR, revascularization and MACE post stenting.
