Apnea Syndrome

Background : Sleep Apnea Syndrome (SAS) is a cause of hypertension, increasingcardiovascular risk and cardiovascular disease such as stroke, coronary artery disease, myocardial infarction, arrhythmias, heart failure, increasing the risk of death in patients with heart disease, independent of other causative factors. So far, in Vietnam there are very few studies on Obstructive Sleep Apnea Syndrome (OSAS) and cardiovascular risk factors . Self-making SASD07 is trustly for detecting OSAS with statistical significiant in comparision with StarDustII (gold criteria). Subjects and Methods: Cross sectional study, comparision with control group: 136 peoples (68 in disease group and 68 in control group). Patients were parallelly measured with StarDustII and SASD07 to detect OSAS and find the corellation with cardiovascular risk factors. Results: There is a positive correlation between SBP with the severity of OSAS (r = 0.459, p < 0.001), positive correlation between DBP with the severity of OSAS (r = 0.352, p < 0.003). No statistically significant differences between severe OSAS and fasting blood glucose, cholesterol, HDL Cholesterol, Non - HDL Cholesterol, LDL Cholesterol and TG median (p > 0.05). There is a positive correlation between AHI and neck circumference (r = 0.511, p < 0.001), waist circumference (r = 0.585, p < 0.001), BMI (r = 0.380, p < 0.01). SASD07 diagnostic value of detecting OSAS compared with StarDustII have Kappa = 0.72, (standard error 0.06, p <0.001). Conclusion: The risk factors related to OSAS in our study is neck circumference, waist circumference, systolic blood pressure, diastolic blood pressure. SASD07 have a good value in diagnosing of OSAS compared with polysomnography StarDustII. Key words: Sleep Apnea Syndrome, cardiovascular risk factor, SASD07.

The review analyzes data from domestic and foreign sources focusing on the current state of a common problem of obstructive sleep apnea syndrome. The article describes the main mechanisms of development and the possible relationships between the cardiovascular diseases, main risk factors in patients, and the sleep-related breathing disorder symptom-complex. The article provides the status update on the problem of continuous positive  airway pressure (CPAP) therapy consisting in creating positive airway pressure ventilation and provides rationale for studying its effects on cardiovascular risk factors in various subgroups of comorbid patients.

Apnea Syndrome

Background: This study aimed to investigate the relation of serum monocyte to serum HDL cholesterol ratio (MHR) with obstructive sleep apnea syndrome (OSAS). A total of 62 patients with an apnea hypopnea index (AHI > 5) and excessive daytime sleepiness were included in this study as OSAS group. The individuals with (AHI) < 5/h were included in the study as controls. OSAS patients were compared with the control group for high density lipoprotein (HDL) levels, serum monocyte count, and monocyte to HDL ratio (MHR). Mild, moderate and severe OSAS subgroups were compared for the same parameters. Results: MHR was 11.93 ± 6.52 in the control group while it was 14.87 ± 6.98 in OSAS group, with a statistically significant difference in between them (p= 0.016). The MHR were positively correlated with AHI and the minimum oxygen saturation (p = 0.003 and p = 0.012, respectively). Conclusion: serum monocyte to serum HDL cholesterol ratio increased as OSAS severity increased. MHR is an easy and available biomarker. It can be used as a new marker for severity of OSAS

Purpose: In the present study we evaluate the corneal endothelium using specular microscopy in patients with obstructive sleep apnea syndrome (OSAS). Methods: The study included a total of 100 patients including 35 patients with mild OSAS, 34 patients with moderate OSAS and 31 patients with severe OSAS, and the right eyes of 30 patients as a control group. Patients were examined to exclude the possibility of ocular diseases. Cellular density in the cornea epithelium (cell/mm2), corneal thickness (µ), percentage of hexagonal cells (%) and the coefficient of variation were evaluated using a specular microscope. Results: Corneal thickness was significantly decreased in all OSAS groups when compared to the control group ( p = 0.002), while no significant difference was identified among the OSAS groups. The corneal endothelial cell density, percentage of hexagonal cells and coefficient of variation were significantly different between the OSAS groups and the control group ( p < 0.001). Conclusion: More significant impairments were noted in the corneal endothelium of the patients in the OSAS group than in the control group, and specular microscopy is in valuable in the follow-up and treatment of such patients.

Apnea Syndrome

Recently, it has been clearly described an independent relationship between obstructive sleep apnea syndrome (OSAS) and cardiovascular risk, with underlying mechanisms also including endothelial dysfunction. We enrolled 32 consecutive non-obese patients (mean age of 39.5±11.5 years), of which 16 with mild OSAS and 16 snoring without OSAS. Mild OSAS is defined by an AHI index between 5 and 15. We have investigated if whether there was a relationship between mild OSAS, endothelial function and carotid intima-media thickness (C-IMT). The population was divided into two groups: Group 1 (16 simple snorer patients with an average age of 39.4±12.1 years) and Group 2 (16 subjects with mild OSAS with an average age of 39.6±11.2 years). Each group underwent cardiovascular investigation including measurement of flow-mediated dilation (FMD) of the brachial artery and C-IMT. Both groups comprised non-obese subjects. Patients with mild OSAS had serum total cholesterol values statistically significantly higher than simple snores patients (178.6±24.9 vs 159.2±25.3; p=0.038). OSAS patients had also a trend towards higher values of maximum C-IMT compared to simple snorer patients (0.70±0.15 vs 0.65±0.16), although below the level of significance. Between the two groups, no difference was found for FMD values. The present results on mild OSAS strengthen the importance of a diagnosis of OSAS as soon as possible, in order to encourage all primary prevention interventions to correct risk factors responsible for disease progression and the occurrence of cardiovascular diseases, not excluding the use of therapies of non-invasive ventilation even in the early stages of the disease.
