    Investigation of The Relationship Between Asthma and Subclinical Atherosclerosis by Carotid/Femoral Intima Media and Epicardial Fat Thickness Measurement
    (2018) Yilmaz, Mustafa; Yilmaz, Hatice Eylul Bozkurt; Sen, Nazan; Altin, Cihan; Tekin, Abdullah; Muderrisoglu, Haldun; https://orcid.org/0000-0002-2557-9579; https://orcid.org/0000-0002-4171-7484; https://orcid.org/0000-0002-5658-870X; https://orcid.org/0000-0002-9635-6313; 28453377; S-6973-2016; AAI-8947-2021; ABD-7304-2021; AAG-8233-2020
    Objective: Since asthma and atherosclerosis may share similar pathophysiological mechanism, this study is planned to investigate whether epicardial fat thickness (EFT), carotid and femoral intima media thicknesses, which are markers of subclinical atherosclerosis, are increased in patients with asthma. Methods: The study was designed as a cross-sectional study. A total of 154 participants (83 patients with asthma and 71 healthy volunteers) were enrolled into the study. Epicardial fat, carotid, and femoral intima media thicknesses were measured and recorded in both groups. The statistical difference between the two groups was examined. Results: Both carotid and femoral intima media thicknesses were significantly higher in patients with asthma compared to control group (5.52 +/- 0.4 mm vs. 5.36 +/- 0.4 mm; p = 0.038 and 5.64 +/- 0.4 mm vs. 5.46 +/- 0.5 mm; p = 0.036, respectively). However, there was not a significant difference in EFT between the groups [5.9 mm (5.3-6.6; IQR = 1.3) vs. 5.6 mm (4.7-6.5; IQR = 1.8); p = 0.1]. On comparison of control group and asthma subgroups (mild, moderate, and severe), there was a statistically significant difference among these four groups in terms of carotid and femoral intima media thicknesses (p = 0.002 and p < 0.001, respectively). Subgroup analyses showed that this difference was mainly due to patients with severe asthma. Conclusions: Carotid and femoral intima media thicknesses in asthmatic patients were found to be increased compared to the normal population. As a result, the risk of subclinical atherosclerosis in asthmatic patients may be high.

    Investigation of the Relationship between Asthma and Visceral Obesity by Epicardial Fat Thickness Measurement
    (2019) Yilmaz, Hatice Eylul Bozkurt; Yilmaz, Mustafa; Sen, Nazan; Unsal, Zuhal Ekici; Eyuboglu, Fusun Oner; Akcay, Sule; 0000-0003-3225-2686; 0000-0002-8360-6459; AAB-5175-2021; 30664419; AAR-4338-2020; AAD-5602-2021
    OBJECTIVES: Obesity is a risk factor defined in recent years for asthma. It is associated not only with asthma but also with many cardiovascular diseases. Visceral obesity is a more significant risk factor than general obesity in cardiovascular diseases. Although the association of visceral obesity with cardiovascular diseases is well known, the relationship in patients with asthma is not fully understood. The aim of the present study was to investigate whether there is a relationship between asthma and visceral fat by using epicardial fat thickness (EFT) measurement. MATERIALS AND METHODS: A total of 401 subjects (229 patients with persistent asthma and 172 controls) were enrolled in the study. In our study, EFT was measured, recorded by echocardiography, and was evaluated whether there was a statistical significant difference between the two groups. RESULTS: The mean EFT was 5.84 +/- 0.79 mm in the patient group and 5.71 +/- 0.93 mm in the control group. There was no statistically significant difference between the groups (p=0.145). Similarly, when we compared control and asthma severity subgroups, we did not find statistically significant differences (control group mean 5.71 +/- 0.93 mm, mild group mean 5.86 +/- 0.81 mm, moderate group mean 5.8 +/- 0.84 mm, and severe group mean 5.83 +/- 0.67 mm, p=0.505). CONCLUSION: In the present study, we observed that the EFT did not increase in patients with asthma compared with the normal population. Based on our results, we suggest that visceral obesity may not be a significant risk factor for asthma.
