Asymptomatic Reactive Hypoglycemia and Inflammatory Reaction in Patients with Coronary Artery Disease.

In this study, the incidence of RH and its effect on arteriosclerosis were examined in CAD patients with a lengthy oral glucose tolerance test (OGTT).We performed a prospective cross-sectional study on 116 nondiabetic CAD patients [70 ± 9 years, 70% male, HbA1c < 6.5%] using coronary angiography and a 4-hour OGTT. Blood samples were collected prior to and 4 hours after the glucose load to evaluate arteriosclerosis markers. Hypoglycemia following the glucose tolerance test was defined as blood glucose levels < 70 mg/dL. We comparatively examined markers of inflammation and arteriosclerosis between the RH group and the non-RH group.A glucose metabolism disorder was observed in 69% of the patients. Hypoglycemia was observed in 24% (28 individuals) of the patients. All showed a RH pattern with no symptoms. The RH group exhibited significantly elevated insulin levels at 1 hour. Furthermore, a significant increase in the white blood cell (WBC) count during OGTT was observed in the RH group compared with the non-RH group [delta WBC; RH: 4.84 (-4.17-20.75) versus non-RH: -2.17 (-9.23-9.09) %; P = 0.04].Asymptomatic RH and an augmentation of inflammation were observed at an incidence of 24% in CAD patients.
