Abstract: Background: This meta-analysis assessed the relationship between Obstructive Sleep Apnea (OSA) and echocardiographic parameters of diastolic dysfunction (DD), which are used in the assessment of Heart Failure with Preserved Ejection Fraction (HFpEF). Methods: We searched the databases including Ovid MEDLINE, Ovid Embase Scopus, Web of Science, Google Scholar, and EBSCO CINAHL from inception up to December 26th, 2020. The search was not restricted to time, publication status or language. Comparisons were made between patients with OSA, diagnosed in-laboratory polysomnography (PSG) or home sleep apnea testing (HSAT), and patients without OSA in relation to established markers of diastolic dysfunction. Results: Primary search identified 2512 studies. A total of 18 studies including 2509 participants were included. The two groups were free of conventional cardiovascular risk factors. Significant structural changes were observed between the two groups. Patients with OSA exhibited greater LAVI (3.94 CI [0.8, 7.07]; p=0.000) and left ventricular mass index (11.10 CI [2.56,19.65]; p=0.000) as compared to control group. The presence of OSA was also associated with more prolonged DT (10.44 ms CI [0.71,20.16]; p=0.04), IVRT (7.85 ms CI[4.48, 11.22]; p=0.000), and lower E/A ratio (-0.62 CI [-1,-0.24]; p=0.001) suggestive of early DD. The E/e’ ratio (0.94 CI[0.44, 1.45]; p=0.000) was increased. Conclusion: An association between OSA and echocardiographic parameters of DD was detected that was independent of conventional cardiovascular risk factors. OSA may be independently associated with DD perhaps due to higher LV mass. Investigating the role of CPAP therapy in reversing or ameliorating diastolic dysfunction is recommended.

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.

Common Finding

Abstract Aim Left ventricular diastolic dysfunction (DD), a common finding in the general population, is considered to be associated with heart failure with preserved ejection faction (HFpEF). Here we evaluate the prevalence and correlates of DD in subjects with and without HFpEF in a middle-aged sample of the general population. Methods and results From the first 10,000 participants of the population-based Hamburg City Health Study (HCHS), 5913 subjects (mean age 64.4 ± 8.3 years, 51.3% females), qualified for the current analysis. Diastolic dysfunction (DD) was identified in 753 (12.7%) participants. Of those, 11.2% showed DD without HFpEF (ALVDD) while 1.3% suffered from DD with HFpEF (DDwHFpEF). In multivariable regression analysis adjusted for major cardiovascular risk factors, ALVDD was associated with arterial hypertension (OR 2.0, p < 0.001) and HbA1c (OR 1.2, p = 0.007). Associations of both ALVDD and DDwHFpEF were: age (OR 1.7, p < 0.001; OR 2.7, p < 0.001), BMI (OR 1.2, p < 0.001; OR 1.6, p = 0.001), and left ventricular mass index (LVMI). In contrast, female sex (OR 2.5, p = 0.006), atrial fibrillation (OR 2.6, p = 0.024), CAD (OR 7.2, p < 0.001) COPD (OR 3.9, p < 0.001), and QRS duration (OR 1.4, p = 0.005) were strongly associated with DDwHFpEF but not with ALVDD. Conclusion The prevalence of DD in a sample from the first 10,000 participants of the population-based HCHS was 12.7% of whom 1.3% suffered from HFpEF. DD with and without HFpEF showed significant associations with different major cardiovascular risk factors and comorbidities warranting further research for their possible role in the formation of both ALVDD and DDwHFpEF.

Background: Ankylosing spondylitis (AS) is a chronic inflammatory condition associated with more cardiac manifestations than those in the normal population. In this study, we sought to determine the prevalence of cardiac involvement in patients suffering from AS without cardiovascular risk factors. Methods: The present case-control study, conducted in 2 university hospitals in Tehran from January 2016 to December 2017, recruited 67 patients with AS and 40 age- and sex-matched healthy controls. The diagnosis of AS was based on the classification criteria of the Assessment of SpondyloArthritis International Society. All the participants were examined using transthoracic echocardiography and a standard 12-lead ECG. Baseline characteristics, echocardiographic findings, and ECG features were compared between the AS and control groups using univariate analyses. Results: The median age was 33.5 (IQR25-75%: 20.5–59) years in the AS group and 35 (IQR25-75%: 26–59) years in the control group (P=0.301). The number of patients with left ventricular systolic and diastolic dysfunction was significantly higher in the patients with AS than in the controls (7.5% vs. 20.9%; P=0.067, and 22.9% vs. 5.0%; P=0.026, respectively). The number of individuals with a left-axis deviation and a left anterior fascicular block was significantly higher in the patients suffering from AS than in the control group. The number of patients with aortic valve involvement was comparable between the groups (P=0.332). Conclusion: The most common cardiac involvement in our patients with AS was left ventricular dysfunction, followed by rhythm disturbances and aortic valve insufficiency. These findings were independent of age, AS severity, and disease duration. Therefore, the implementation of cardiovascular screening can be recommended for patients with AS.

One Year

Background: Despite efforts at treatment, obstructive sleep apnea (OSA) remains a major health problem, especially with increasing evidence showing an association with cardiovascular morbidity and mortality. The treatment of choice for OSA patients is Continuous Positive Airway Pressure (CPAP), which has been proven in randomized controlled trials to be an effective therapy for this condition. The impact of CPAP on the cardiovascular pathology associated with OSA remains, however, unclear. Although the effect of CPAP has been previously studied in relation to cardiovascular outcome, follow-up of the treatment impact on cardiovascular risk factors at one year of therapy is lacking in a Romanian population. Thus, we aimed to evaluate the one-year effect of CPAP therapy on lipid profile, inflammatory state, blood pressure and cardiac function, assessed by echocardiography, on a cohort of Romanian OSA patients. Methods: We enrolled 163 participants and recorded their baseline demographic and clinical characteristics with a follow-up after 12 months. Inflammatory and cardiovascular risk factors were assessed at baseline and follow up. Results: Our results show that CPAP therapy leads to attenuation of cardiovascular risk factors including echocardiographic parameters, while having no effect on inflammatory markers. Conclusion: Treatment of OSA with CPAP proved to have beneficial effects on some of the cardiovascular risk factors while others remained unchanged, raising new questions for research into the treatment and management of OSA patients.
