          Association of Vascular Endothelial Growth Factor Gene Polymorphism with Myocardial Infarction in Patients with Type 2 Diabetes

          Background: Many studies have reported increased serum levels of vascular endothelial growth factor (VEGF) in patients with acute coronary syndromes. We searched for the association between either the –634 C/G or the insertion/deletion (I/D) polymorphism of the VEGF gene and myocardial infarction (MI) in subjects with type 2 diabetes. Methods: 143 subjects with type 2 diabetes and MI were compared to 228 diabetic subjects without coronary artery disease (CAD). VEGF serum levels were analyzed in 94 subjects with type 2 diabetes without CAD. Results: A significantly higher frequency of the CC genotype of the –634 C/G VEGF polymorphism was found in the patients with MI compared to the patients without CAD (17.5 vs. 9.2%; p = 0.019), whereas the insertion/deletion VEGF polymorphism failed to yield an association with MI. Significantly higher VEGF serum levels were demonstrated in subjects with the CC genotype compared to those with the other (CG + GG) genotypes (60.4 ± 32.1 vs. 44.1 ± 23.5 ng/l; p < 0.01). Conclusions: The present study demonstrates that the CC genotype of the –634 C/G VEGF gene might be a risk factor for MI in Caucasians with type 2 diabetes of duration of more than 10 years.

            Usefulness of Red Cell Distribution Width in Predicting All-Cause Long-Term Mortality after Non-ST-Elevation Myocardial Infarction

            Background: Red blood cell distribution width (RDW) is a strong predictor of adverse outcomes in patients with heart failure, stable coronary artery disease, stroke and acute myocardial infarction. The aim of our study was to explore the predictive value of RDW on all-cause mortality in patients with non-ST-segment elevation myocardial infarction (NSTEMI). Method: This observational study includes 619 NSTEMI patients, discharged from Staten Island University Hospital between September 2004 and December 2006. Patients were divided into equal RDW tertiles and survival was evaluated in each tertile. Result: Patients in the highest RDW tertile (RDW >14) had higher in-patient (7 vs. 1%) and 4-year (30 vs. 7%) mortality rates compared to those in the lowest tertile (RDW 2 = 34.64, p < 0.0001). After controlling for Global Registry of Acute Coronary Events risk profile scores and other confounding variables, the RDW adjusted hazard ratio for 4-year all-cause mortality increased by 1.10 for each one unit increase in RDW (confidence interval 1.004–1.213, p = 0.042). Conclusion: RDW is an independent predictor of all-cause long-term mortality in NSTEMI patients. Further studies are needed to clarify the mechanisms of this association between RDW and adverse outcomes in patients with coronary artery disease.

              Evaluation of the mean platelet volume in patients with cardiac syndrome X

              OBJECTIVE: Cardiac syndrome X is characterized by angina-like chest pain, a positive stress test, and normal coronary arteries. A patient's mean platelet volume, which potentially reflects platelet function and activity, is associated with coronary atherosclerosis and endothelial dysfunction. The aim of the present study was to evaluate the mean platelet volumes of patients with cardiac syndrome X, those with coronary artery disease and normal subjects. METHODS: Two hundred thirty-six subjects (76 patients with cardiac syndrome X, 78 patients with coronary artery disease, and 82 controls) were enrolled in the study. All of the subjects were evaluated with a detailed medical history, physical examination, and biochemical analyses. The mean platelet volumes were compared between the three groups. RESULTS: The mean platelet volumes in the patients with cardiac syndrome X and with coronary artery disease were significantly higher than those that were observed in the control group. There were no significant differences in the mean platelet volumes between the cardiac syndrome X and the coronary artery disease groups. CONCLUSION: We have established that patients with cardiac syndrome X and coronary artery disease exhibit higher mean platelet volumes compared to controls. Patients with cardiac syndrome X exhibited higher mean platelet volumes compared to the controls, reflecting the presence of subclinical atherosclerosis. These findings suggest that, in addition to endothelial dysfunction, the presence of atherosclerosis may also contribute to the etiopathogenesis of cardiac syndrome X.
