BACKGROUND: Recent studies suggested that the association of acute glucose variability and diabetic complications was not consistent, and that A1c variability representing long term glucose fluctuation may be related to coronary atherosclerosis in patients with type 1 diabetes. In this study, we attempt to determine whether or not A1c variability can predict coronary artery disease (CAD) in patients with type 2 diabetes. METHODS: We reviewed data of patients with type 2 diabetes who had undergone coronary angiography (CAG) and had been followed up with for 5 years. The intrapersonal standard deviation (SD) of serially-measured A1c levels adjusted by the different number of assessments among patients (adj-A1c-SD) was considered to be a measure of the variability of A1c. RESULTS: Among the 269 patients, 121 of them had type 2 diabetes with CAD. In patients with A1c > or =7%, the mean A1c levels and A1c levels at the time of CAG among the three groups were significantly different. The ratio of patients with CAD was the highest in the high adj-A1c-SD group and the lowest in the low adj-A1c-SD group (P=0.017). In multiple regression analysis, adj-A1c-SD was an independent predictor for CAD in subjects with A1c > or =7% (odds ratio, 2.140; P=0.036). CONCLUSION: Patients with higher A1c variability for several years showed higher mean A1c levels. A1c variability can be an independent predictor for CAD as seen in angiographs of patients with type 2 diabetes with mean A1c levels over 7%.

OBJECTIVETo evaluate the clinical and coronary angiographic features of patients with systemic vasculitis and coronary artery disease.

METHODFifteen patients (11 male) with systemic vasculitis and coronary artery diseases admitted to our hospital from January 1999 to October 2009 were reviewed.

RESULTSThere were 6 patients with Behcet's disease, 3 patients with Churg-Strauss syndrome, 2 patients with Takayasu arteritis, 1 patient with polyarteritis nodosa, 1 patient with microscopic polyangiitis, 1 patient with Wegner's granulomatosis and 1 patient with Kawasaki disease. Mean age of this cohort was (39.3 ± 11.9) years. Adverse coronary events occurred in 4 patients during the inactive phase of systemic vasculitis and in 9 patients during the active phase of systemic vasculitis. Twelve patients were hospitalized with acute myocardial infarction, 2 with angina pectoris and 1 with cardiac tamponade. There were 3 patients with acute left ventricular dysfunction and 3 patients with severe arrhythmias. Compared to patients in the inactive phase, patients in the active phase were younger [(32.4 ± 8.1) years vs. (47.0 ± 10.2) years], had less risk factors for atherosclerosis (1.2 ± 1.5 to 2.8 ± 1.7) and the time intervals between coronary artery disease and systemic vasculitis was shorter [0 - 7 years (average 1.6 years) to 3 - 30 years (average 17.7 years)]. Coronary angiography evidenced coronary stenosis or occlusions in 11 patients, coronary aneurysm and acute thrombosis in 1 patient, coronary aneurysms and occlusions in 1 patient and coronary spasm in 2 patients. LVEF measured by echocardiography was less than 50% in 8 patients.

CONCLUSIONPatients with various systemic vasculitis could develop severe coronary artery disease due to coronary stenosis/occlusion, aneurysma, thrombosis and coronary spasm.

To investigate the association of pancreatic steatosis with coronary atherosclerosis in patients with type 2 diabetes mellitus (T2DM). Patients with T2DM who underwent coronary computed tomography angiography(CCTA)in our center due to chest pain were enrolled from January 2016 to February 2019. According to the CCTA findings,patients were divided into normal group,mild-to-moderate coronary atherosclerosis group and severe coronary atherosclerosis group. CT attenuation of pancreas and spleen was measured on abdominal non-enhanced CT,and the CT attenuation indexes including the difference between pancreatic and splenic attenuation (P-S) and the ratio of pancreas-to-spleen attenuation (P/S) were calculated. Analysis of variance or Kruskal-Wallis rank test were used to assess differences among each group. Logistic regression analysis was used to analyze the risk factors of severe coronary stenosis. The accuracy of P/S in predicting severe coronary artery stenosis was assessed by receiver operator characteristic (ROC) curve analysis. A total of 173 consecutive T2DM patients were enrolled. These patients included 27 patients with normal coronary artery (15.6%),124 patients with mild to moderate stenosis (71.7%),and 22 patients with severe stenosis (12.7%). There were significant differences in CT attenuation of pancreas (=11.543,=0.003),P-S (=11.152,=0.004) and P/S (=11.327,=0.004) among normal coronary artery group,mild and moderate stenosis group,and severe stenosis group. The CT attenuation of pancreatic head,body,and tail significantly differed in patients with coronary artery stenosis (=14.737,=0.001). After adjusting for confounding factors,multiple Logistic regression showed that P/S (=0.062,95%=0.008-0.487,=0.008) was still significantly associated with the severe coronary artery stenosis. The area under the ROC curve of P/S for the diagnosis of severe coronary artery stenosis was 0.701,and the optimal cutoff point was 0.660. CT attenuation of pancreas and CT attenuation indexes are associated with the severity of coronary stenosis in T2DM patients,suggesting that pancreatic steatosis may be used as one of the indicators for predicting severe coronary artery stenosis.
