Prognostic value of fasting glucose levels in elderly patients with acute coronary syndrome.

BACKGROUND
The fasting plasma glucose (FPG) test is a predictor of complications after Acute Coronary Syndrome (ACS). However, its prognostic value is not yet fully established in different age groups.


OBJECTIVE
To evaluate the role of admission fasting plasma glucose (FPG) as a predictor of 30 days after ACS, and the association of hyperglycemia with major cardiovascular events (MACE): death, reinfarction and coronary artery bypass grafting, in two different age groups (<65 year and ≥65 year-old patients).


METHODS
Contemporary cohort of patients hospitalized for ACS in the Institute of Cardiology of Rio Grande do Sul (Southern Brazil). In the first 24 hours of admission, patients answered a questionnaire with clinical information and had peripheral blood collected for measurement of FPG. Patients were followed up during hospitalization and for 30 days for the presence of MACE. Statistical analyses were performed using the SPSS 15.0 with the chi-square or Fisher Exact test (categorical variables) and the Student t test (numerical variables). Multivariate analysis was performed.


RESULTS
580 patients were included in the study. Mean age was 61.2 (±12.3) years, with 38.6% of the patients (224) ≥65 years old, and 67.7% (393) were male. Multivariable analysis showed that, after 30 days of follow-up, only FPG (OR= 1.01, 95% CI:1.00-1.01, P= 0.001) was associated with MACE in both age groups.


CONCLUSION
Admission FPG was an independent predictor for MACE in the early phase of ACS.
