“…Subendocardial dysfunction subsequently complicates the longutidinal contractile function. Interestingly, the reduction in longutidinal function is initially compensated by radial and circumferential function aggravation because of the cross-fiber shorting phenomenon (33). In the present study, although the TDI-S was not significantly different among OSA patients and healthy individuals, the S value was found to be decreased along with the disease severity.…”

Objective: We aimed to evaluate the subclinical left ventricular (LV) systolic dysfunction with the automated function imaging method (AFI) based on speckle tracking echocardiography (STE) in obstructive sleep apnea patients (OSA) with normal left ventricular ejection fraction (LVEF) and without any confounding disease that can cause myocardial dysfunction. Methods: Twenty-one healthy individuals and 58 OSA patients were included in this observational cross-sectional study. According to the severity of disease, OSA patients were examined in three groups; mild, moderate and severe OSA. Apical 2-, 3-and 4-chamber images were obtained for AFI evaluation. The global systolic longitudinal strain (GL S ) values were determined for each view, and averages of these were used in comparison of the patient groups. One-way ANOVA, Kruskal-Wallis, Pearson correlation tests and linear regression analysis were used for statistical analysis. Results: The GL S values of the OSA patients were lower than of the healthy individuals and these values were decreased along with the OSA severity (Healthy:-25.58±-2.16%, Mild:-23.93±-3.96%, Moderate:-21.27±-2.60%, Severe:-16.94±-2.66%, respectively). The difference was significant between moderate OSA patients and healthy individuals, and significant between severe OSA patients and all other groups (p<0.03). The apnea-hypopnea index was found to be correlated with the GL S (β=-0.659, 95% CI: 0.09-0.17, p<0.001). Conclusion: Longitudinal LV mechanics in OSA patients with normal LVEF are deteriorated in the subclinical stage being associated with the severity of disease. AFI can be used as an effective and safe method in the determination of subclinical myocardial dysfunction in OSA patients, because it is semi-automated and easy to use with a short analysis time.(Anadolu Kardiyol Derg 2012; 12: 320-30) Key words: Obstructive sleep apnea, speckle tracking echocardiography, myocardial strain, regression analysis 320 ÖZET Amaç: Sol ventrikül ejeksiyon fraksiyonu normal ve miyokart fonksiyonlarını etkileyecek ek hastalığı bulunmayan, obstrüktif uyku apneli (OUA) hastalarda, subklinik sol ventrikül sistolik disfonksiyonunu, iki boyutlu benek izleme ekokardiyografi tekniğine dayanan, otomatik fonksiyonel görün-tüleme yöntemi (OFG) ile değerlendirmeyi amaçladık.

A b s t r a c tBackground: Prosthesis-patient mismatch (PPM) is an independent predictor of post-operative mortality after aortic valve replacement (AVR), particularly when it is associated with a left ventricle (LV) dysfunction. Two-dimensional speckle-tracking echocardiography (2D-STE) could be useful in assessing LV function in patients with PPM. Aim:To evaluate the impact of PPM on myocardial multidirectional LV systolic strain in patients who are undergoing AVR for severe degenerative aortic stenosis (AS). Methods:Sixty-five patients (38 females, 27 males, age: 69.9 ± 9.1 years) with severe degenerative AS and preserved LV ejection fraction were enrolled into the study. Pre-and three-month postoperative 2D-STE was performed to assess LV peak systolic longitudinal strain (LV PSLS), circumferential strain, and LV rotation. The indexed prosthesis effective orifice area (iEOAprosth) was used to define PPM (≤ 0.65 cm 2 /m 2 ), and it was used to distinguish the study groups: PPM (+) (n = 35) and PPM (-) (n = 30).Results: A significant association of LV PSLS and interaction in the groups [PPM (+) vs. PPM (-)] and intervention (before vs. after AVR; p = 0.019) was observed -the lowest value of LV PSLS was in the PPM (+) group (-14.9 ± 3.5%) after AVR. A significant difference in the mean delta (before/after AVR) values of LV PSLS (0.7 ± 3.1% vs. -1.2 ± 3.6%; p = 0.04) in the PPM (+) vs. the PPM (-) groups was found. LV PSLS correlated with iEOAprosth (r = -0.520, p < 0.001) that was obtained three months after AVR. Conclusions:The occurrence of PPM in patients undergoing AVR for severe degenerative AS was associated with reduced LV PSLS in a three-month observation.

Introduction. Heart failure with preserved left ventricular ejection fraction (HFPEF) is an epidemiologically serious disease. Noninvasive diagnosis of HFPEF remains challenging. The current diagnosis is based on evidence of diastolic dysfunction, albeit systolic dysfunction is also present but not included in the diagnostic algorithm. The aim of this study was to analyze the longitudinal (long), circumferential (circ) and radial (rad) component of systolic left ventricular (LV) function in patients with exertional dyspnea of unexplained etiology and normal left ventricular ejection fraction (LVEF). Methods. One hundred and twenty-two patients with exertional dyspnea of unexplained etiology and normal LVEF and 21 healthy controls, underwent echocardiography examination at rest and at the end of symptom-limited exercise. We analysed the longitudinal, circumferential and radial deformation of myocardium using two dimensional speckle tracking echocardiography in all subjects. Results. Patients with exertional dyspnea and preserved LVEF were divided into group A1 (46 patients meeting the criteria for the diagnosis HFPEF) and group A2 (76 patients without HFPEF). Group A1 had significantly worse longitudinal and circumferential systolic LV function than group A2. Subjects in group A1 compared to group A2 showed significantly different strain rates during atrial contraction (SR A), circ and ratio of peak early trans-mitral flow velocity (E) and strain rate E wave (E / SR E) circ. Multivariate logistic regression analysis showed that the SR parameter A circ is an independent predictor of HFPEF (odds ratio 0.550, 95% confidence interval: 0.370 -0.817, P value 0.003). Conclusion. Longitudinal and circumferential LV deformation was significantly more impaired in patients with HFPEF than in patients with exertional dyspnea without HFPEF. In patients with exertional dyspnea and normal LVEF, the value of SRA circ appears to be a significant and independent predictor of HFPEF. This parameter may, in the future complement the diagnostic algorithm for HFPEF.
