[Association between fasting plasma glucose and the 5 years outcome post PCI in aged patients with coronary artery disease].

ABSTRACT

OBJECTIVE: To observe the association between fasting plasma glucose (FPG) and 5 years outcome post PCI in aged patients with coronary artery disease (CAD). METHODS: A total of 269 patients (mean age 63.8 +/- 9.4 years, 236 males) with CAD underwent PCI between January 2000 and December 2001 were followed up and data on angiographic restenosis, the major adverse cardiac events, the cumulative survival rates and the correlated risk factors were collected and analyzed. Patients were divided into 4 groups according to the levels of their FPG at baseline (group 1 FPG < 5.6 mmol/L; group 2 5.6 mmol/L < or = FPG < 6.1 mmol/L; group 3 6.1 mmol/L < or = FPG < 7.0 mmol/L; group 4 FPG > or = 7.0 mmol/L). RESULTS: At the end of the 5 years follow-up, the incidences of major adverse cardiac events, target lesion revascularization, recurring angina pectoris and angiographic restenosis of group 2 were significantly higher than those of group 1 (P < 0.05) and similar as those in group 3 (P > 0.05). The cumulative survival rates of cardiovascular events of group 2, group 3 and group 4 were all significantly decreased compared with group 1 (P < 0.05). The logistic regression model analysis showed that FPG was an independent risk factor for angiographic restenosis, incidence of major adverse cardiac events, all-cause mortality and recurring angina pectoris (P < 0.05). CONCLUSION: FPG > or = 5.6 mmol/L and over is associated with increased incidences of major adverse cardiac events in aged patients with CAD who underwent PCI.
