Abstract：
Obstructive (OA) and central apneas (CA) are highly prevalent breathing disorders that have a negative impact on cardiac structure and function; while OA promote the development of progressive cardiac alterations that can eventually lead to heart failure (HF), CA are more prevalent once HF ensues. Therefore, the early identification of the deleterious effects of apneas on cardiac function, and the possibility to detect an initial cardiac dysfunction in patients with apneas become relevant. Speckle tracking echocardiography (STE) imaging has become increasingly recognized as a method for the early detection of diastolic and systolic dysfunction, by the evaluation of left atrial and left and right ventricular global longitudinal strain, respectively. A growing body of evidence is available on the alterations of STE in OA, while very little is known with regard to CA. In this review, we discuss the current knowledge and gap of evidence concerning apnea-related STE alterations in the development and progression of HF.
摘要：
阻塞性（OA）和中枢呼吸暂停（CA）是非常普遍的呼吸障碍，对心脏结构和功能有负面影响;而OA促进进行性心脏改变的发展，最终可能导致心力衰竭（HF），一旦HF发生，CA更为普遍。因此,早期识别呼吸暂停对心脏功能的有害影响，并且在呼吸暂停患者中检测到初始心脏功能障碍的可能性变得相关。斑点追踪超声心动图（STE）成像已越来越被认为是早期发现舒张和收缩功能障碍的一种方法。通过评估左心房和左右心室整体纵向应变，分别。越来越多的证据表明OA中STE的改变，虽然对CA知之甚少。在这次审查中,我们讨论了目前关于呼吸暂停相关STE改变在HF发生和进展中的知识和证据差距.
