Abstract

We evaluated if admission glycosylated hemoglobin (HbA1c ) and fasting glucose levels are correlated with the severity of coronary artery disease (CAD) in non-ST-elevation myocardial infarction (NSTEMI), nondiabetic, patients. Coronary artery disease severity, according to the anatomical synergy between percutaneous coronary intervention (PCI) with taxus and cardiac surgery (SYNTAX) score 2 (SSII), was retrospectively evaluated in 359 nondiabetic patients hospitalized with NSTEMI who underwent coronary angiography. Glucose intolerance was assessed by serum fasting glucose and HbA1c levels. We stratified patients according to tertiles of SSII (≤21.5, 21.5-30.6, and ≥30.6). These score ranges were defined as SSII low, SSII mid, and SSII high, respectively. The average age of the patients was 57.1 ± 10.9 years; 189 (52.1%) patients were males. The average fasting glucose was 114 ± 52 mg/dL, HbA1c was 5.8% ± 0.9%, and SSII was 18.9 ± 10.3. A stronger correlation was found between HbA1c and SSII than fasting glucose and SSII (r1 = 0.901, P < .001, r2 = 0.378, P < .001, respectively), and HbA1c level and hypertension were independent risk factors for SSII high (odds ratio [OR]: 2.2 (95% CI: 0.5-9.0, P < .001; OR: 1.1 (1.0-1.3), P = .007, respectively). In conclusion, in nondiabetic patients with NSTEMI, HbA1c levels correlated with CAD severity as measured by the SSII.
