LA remodeling and dysfunction that accompany OSA can be detected in the subclinical stage with a detailed evaluation of active and passive functions of the LA using the 2D-STE method.

The significance of the left atrial volume index in cardioversion success and its relationship with recurrence in patients with non-valvular atrial fibrillation subjected to electrical cardioversion: a study on diagnostic accuracy ABSTRACTObjective: The aim of this study was to assess the predictive value of the left atrial volume index (LAVI) in electrical cardioversion (ECV) and observe the recurrence rate of atrial fibrillation (AF) after a successful ECV in patients with non-valvular atrial fibrillation.Method: This study was designed as a diagnostic accuracy and prospective cohort study. Eighty patients (mean age 62±12 years; 52.5% female) were enrolled in study. LAVI was measured using the area-length method and the indexed body surface area. Patients in whom the sinus rhythm (SR) was established following the ECV were assessed according to the clinical and electrocardiography (ECG) findings at the first month and grouped as those with continued SR or recurrent AF. The Student's t, Mann-Whitney U, Fisher's exact, Chi-square tests, ROC and logistic regression analyses were used for statistical analysis.Results: Subsequent to the ECV, SR was achieved in 62.5% (n=50) Original Investigation Özgün Araşt›rma 18ÖZET Amaç: Çalışmamızın amacı, valvüler olmayan atriyal fibrilasyonlu (AF) hastalarda, sol atriyum volüm indeksi (SAVİ) ile elektif elektriksel kardiyoversiyon (EKV) başarısı ve başarılı EKV sonrası erken dönem AF tekrarı arasındaki ilişkiyi araştırmaktır. Yöntem: Bu araştırma tanısal ve ileriye dönük kohort bir çalışma olarak tasarlandı. Çalışmamıza toplam 80 hasta (ortalama yaş 62±12 yıl, %52.5 kadın) alındı. Sol atriyal volüm alan-uzunluk yöntemi ile belirlendi, vücut-yüzey alanına bölünerek SAVİ hesaplandı. Hastalar öncelikle EKV'nin sonucuna göre sinüs ritmi (SR)-AF olarak ve EKV sonrası SR sağlananlar kendi içerisinde 1. ay klinik ve elektrokardiyografi (EKG) bulgularına göre SR devam edenler ve AF gelişenler olarak ayrıldı. Student's t, Mann-Whitney U, Fisher's exact, Chi-square testleri, ROC ve lojistik regresyon analizleri istatistiksel değerlendirme için kullanıldı.

In patients with ESRD, although the longitudinal and radial systolic functions are reduced, the LVEF may remain within normal limits due to the preservation of the circumferential functions. 2D-STE has the potential to detect the severity of uraemic cardiomyopathy in the early stages of the disease and might provide useful information for the risk stratification in ESRD patients with PLVEF.

By using two-dimensional speckle tracking echocardiography, we aimed to investigate the structural and functional changes on myocardium in chronic asymptomatic alcoholics without any cardiovascular disease. Forty-one consecutive asymptomatic male alcoholics who were admitted to the outpatient alcoholism unit and 30 age matched healthy male volunteers selected as the control group were enrolled in the study. The study group were investigated by using standard two-dimensional echocardiography and speckle tracking echocardiography. The left ventricular (LV) global longitudinal strain and LV global circumferential strain were significantly lower in alcoholics when compared with control subjects. There was no difference in global radial strain between the two groups. To demonstrate the effect of total life time dose of ethanol (TLDE) on echocardiographic abnormalities, we assessed the correlation analysis. There was a nonsignificant weak correlation between global LV circumferential strain and TLDE (r = 0.27, p = 0.083). Speckle tracking echocardiography derived left ventricular systolic function was impaired in chronic alcoholic patients when compared with healthy controls.

Our results suggest that OSAS patients tend to have relatively increased platelet activation andatherothrombotic risk.
