Objectives: Elastin is a major structural protein of arteries and elastin derived peptide is known to be related to arterial change. We previously reported a novel assay for anti-aortic elastin antibody, but its clinical implication has not been clearly shown. The aim of this study was to check if anti-aortic elastin antibody titers may reflect the risk of coronary artery disease (CAD) or its detail characteristics. Methods: This study included 174 CAD patients and 171 age-, sex-matched control subjects. In all subjects, anti-aortic elastin antibody titer was quantified by ELISA. Parameters of arterial stiffness including augmentation index (AI) and heart to femoral pulse wave velocity (hfPWV) were measured non-invasively. In patients with CAD, clinical and angiographic characteristics were evaluated. Associations between anti-aortic elastin and vascular characteristics were identified by linear regression analysis. Results: Median blood level of anti-aortic elastin was significantly lower in the CAD group than that of the control group (197 a.u. vs. 63 a.u., p<0.001). Levels of anti-aortic elastin were significantly lower in males, subjects with hypertension, diabetes mellitus, hyperlipidemia, or hfPWV (Figure). However, the levels were not dependent of atherothrombotic events or angiographic severity of CAD (Figure). In multivariate analysis, male (β=-0.38, p<0.001), diabetes mellitus (β=-0.62, p<0.001), hyperlipidemia (β=-0.29, p<0.001), and AI (β=-0.006, p=0.02) were finally identified as determinants for anti-aortic elastin levels (Table). Conclusions: Taken together, lower levels of anti-aortic elastin are related to CAD. The association between antibody titer and CAD is linked to arterial stiffness rather than advancement of atherosclerosis.

Abstract Introduction Surgical early menopause is early menopause due to medical reasons rather than the natural aging process. Pulse wave velocity (PWV) and augmentation index (AIx) are simple and non-invasive parameters for assessment of arterial stiffness. The aim of this study investigated the arterial stiffness in the surgical early menopause patients. Method We included 40 patient early surgical menopause and 40 control group patients with clinically and demographically similar characteristics. Oscillometric measurement method with Mobil-O-Graph 24h-ABPM NG® arteriography was used to measure the arterial stiffness and cardiovascular hemodynamic parameters. Results Of the 40 patients who underwent surgical early menopause, 27 (67.5%) had malignancy, 11 (27.5%) with myoma and 2 (5%) with bleeding. There were no differences in baseline demographic, laboratory, echocardiographic parameters and coronary artery disease risk factors.In terms of arterial stiffness parameters, PWV were significantly higher in the early surgical menopause group than in the control group (6.5±0.8; 5.6±1.2 p&lt;0.001), but there was no statistically significant difference in Alx (28.3±10.9; 27.4±9.0 p=0.69).Also, there was no statistically significant difference in terms of cardiac hemodynamic parameters and central aortic pressures. Conclusion When arterial stiffness is noninvasively evaluated by oscillometric method, it is significantly increased in surgical early menopause patients independent of other risk factors.

The Relationship

Objective : Many studies have indicated arterial stiffness as an independent predictor of hypertension, stroke, cardiovascular events, and mortality. However, the relationship between the severity of coronary artery disease(CAD) and arterial stiffness is still unclear. In this study, it was aimed to examine the relationship between augmentation index which is a marker of arterial stiffness with CAD and its prevalence. Methods: A total of 80 patients (22 women, mean age 59±8) who were scheduled for coronary angiography with a preliminary diagnosis of coronary artery disease by evaluating their symptoms and findings and coronary risk profiles were included. The other group have 20 healthy patients without any chronic disease history. The augmentation index (AIX), which is an indicator of arterial stiffness, was measured in all cases with the BP+ Central Blood Pressure CardioScope II device in all groups. Gensini score of the patient group was calculated. Results: It was found to be 131% (79-198mmHg) in the AIX patient group and 72.5% (69-96mmHg) in the control group (p<0.001). A positive correlation was observed between AIX and Gensini score, LDL-cholesterol, body mass index and HbA1c in the patient group. In the ROC analysis, the area under the curve (AUC) for AIX was calculated as 0.701 (P<0.001). While AIX was 121% above normal, it predicted coronary artery disease with 94.8% sensitivity and 80.9% specificity. Conclusion: In our study, a relationship was found between coronary artery disease with its severity and arterial stiffness. Augmentation index can be used effectively with low cost in predicting coronary artery disease.

Abstract. Increased arterial stiffness results from reduced elasticity of the arterial wall and is an independent predictor for cardiovascular risk. The gold standard for assessment of arterial stiffness is the carotid-femoral pulse wave velocity. Other parameters such as central aortic pulse pressure and aortic augmentation index are indirect, surrogate markers of arterial stiffness, but provide additional information on the characteristics of wave reflection. Peripheral arterial disease (PAD) is characterised by its association with systolic hypertension, increased arterial stiffness, disturbed wave reflexion and prognosis depending on ankle-brachial pressure index. This review summarises the physiology of pulse wave propagation and reflection and its changes due to aging and atherosclerosis. We discuss different non-invasive assessment techniques and highlight the importance of the understanding of arterial pulse wave analysis for each vascular specialist and primary care physician alike in the context of PAD.

Background: Type 2 diabetes mellitus (T2DM) is a chronic condition with an impairing effect on multiple organs. Numerous respiratory disorders have been observed in patients with T2DM. However, T2DM e ect on pulmonary function is ff inconclusive. Aims: In this study, we investigated the effect of T2DM on respiratory function and the correlation of glycemic control, diabetes duration and insulin intake. Methods: 1500 patients were recruited for this study, 560 having T2DM for at least a year were included in the final data, in addition to 540 healthy volunteers. Forced expiratory volume in one second (FEV1), forced vital capacity (FVC), forced expiratory flow at 25-75% (FEF 25-75%), as well as FEV1/FVC ratio values were measured. Results: A two-sample t-test showed that z-scores produced by Al-Qerem et al.’s equations for FEV1, FVC, and FEF 25-75% were significantly lower for the T2DM group than the control group (p < 0.01). FEV1/FVC ratio in T2DM group were significantly higher (p < 0.01). Multiple linear regression analysis found that glycemic control represented by HbA1c as well as disease duration were negatively associated with pulmonary function (p < 0.01). However, insulin intake was found to have no significant correlation with the pulmonary function. Conclusion: T2DM was linked to reduced pulmonary function and was consistent with a restrictive ventilation pattern. HbA1c as well as disease duration were independent risk factors for reduced pulmonary function.

Objective: An effective clinical tool to assess endothelial function and arterial stiffness in patients with obstructive sleep apnea (OSA) is lacking. This study evaluated the clinical significance of subclinical markers for OSA management in males without serious complications.Patients/Methods: Males without serious complications were consecutively recruited. Clinical data, biomarker tests, reactive hyperemia index (RHI), and augmentation index at 75 beats/min (AIx75) measured by peripheral arterial tonometry were collected. An apnea hypopnea index (AHI) cutoff of ≥15 events/h divided the patients into two groups.Results: Of the 75 subjects, 42 had an AHI ≥15 events/h. Patients with an AHI ≥15 events/h had higher high-sensitivity C-reactive protein, tumor necrosis factor-alpha (TNF-α), vascular endothelial growth factor, and AIx75 values than the control group but no statistical difference in RHI was observed. After controlling for confounders, TNF-α was negatively correlated with the average oxygen saturation (r = −0.258, P = 0.043). RHI was correlated with the rapid eye movement (REM) stage percentage (r = 0.306, P = 0.016) but not with AHI (P &gt; 0.05). AIx75 was positively correlated with the arousal index (r = 0.289, P = 0.023) but not with AHI (r = 0.248, P = 0.052).Conclusions: In males with OSA without severe complications, TNF-α and AIx75 are independently related to OSA. The role of RHI in OSA management requires further elucidation. These markers combined can comprehensively evaluate OSA patients to provide more evidence for the primary prevention of coronary heart disease and treatment response assessment.

Diabetes Mellitus (DM) merupakan penyakit yang tidak dapat disembuhkan, namun dapat dikendalikan. Prevalensi penderita DM di Indonesia 6.9% dan di Jawa Barat sekitar 29,4% dari jumlah penduduknya. Sebagai mother of desease, penyakit DM memiliki komplikasi yang serius seperti retinopati diabetik, neuropati, amputasi, penyakit jantung, gagal jantung, stroke dan peripheral arterial disease. Kondisi tersebut menunjukkan perlunya keseriusan dalam penanganan penyakit DM. Diperlukan dukungan dari kader (sebagai bagian dari support group) bagi peserta prolanis DM. Tujuan penelitian ini adalah untuk mengetahui implementasi metoda support group dalam meningkatkan persepsi pasien tentang perawatan DM di Kota Bandung. Penelitian ini termasuk jenis penelitian kuantitatif dengan menggunakan rancangan quasi experiment dengan pretest and post test non equivalent control group. Hasil penelitian menunjukkan peningkatan persepsi pasien prolanis sebesar 3,08 dan peningkatannya dinyatakan sangat bermakna (p<0,01).  Edukasi yang dilakukan kader (support group) berpengaruh terhadap peningkatan persepsi pasien DM. Metode support group dengan memberdayakan kader dalam memberikan edukasi sangat bermanfaat dan dapat dijadikan kebijakan di pelayanan kesehatan masyarakat.
