Bacterial infections could contribute to atherosclerotic inflammation. We investigated the association of Coxiella Burnetii seropositivity with the atherosclerotic lesion types (obstructive and/or ectatic), serum lipid profile, nitric oxide (NO),total sulfhydryl (SH) groups and malonyldialdehyde (MDA) levels. A total of 150 participants (73 male, mean age: 56.6 ± 11.4 years; 77 female, mean age: 57.3 ± 13.0 years) were enrolled into the study. Coronary angiography was performed all the participants. We also performed serum lipid profile, NO, SH groups and MDA levels to determine the changes in chronic and acute Coxiella burnetii infections. The patients with obstructive and ectatic coronary artery lesions were of higher Coxiella phase I IgG titer (The marker of chronic Coxiella infection) than those of other coronary artery disease groups(One Way ANOVA, p=0.001). There were higher serum total cholesterol levels in the patients with chronic Coxiella infection than those of other patients. The chronic Coxiella Burnetii infection may be an important factor for the formation of coronary artery ectasia on basement of atherosclerotic coronary artery disease. Hyperlipidemia might also facilitate and augment this association.

In this study, we aimed to investigate the correlations of serum Orexin-A level (SOAL) and the severity of coronary artery disease (CAD). A total of 80 participants (mean age: 55.7±12.7 years) were enrolled into the study. SOAL, electrocardiography and transthoracic echocardiography and 24 Hour Holter monitoring (24HHM) and coronary angiography were performed in all participants. Autonomic functions were assessed using the data of Heart Rate Variability measurements. Patients were categorized into three groups according to their Gensini scores as: Group 1: The patients with normal coronary angiogram, Group 2: The patients with mild CAD (Gensini
