背景：心脏移植（HTx）后的心功能受到多种因素的影响。通常使用经胸超声心动图对其进行评估，但目前尚无针对此情况的参考值。本研究的主要目的是得出临床稳定的 HTx 患者的心室大小和功能（包括心脏力学）的超声心动图参考值。方法：该研究纳入了 124 名健康 HTx 患者，进行了前瞻性检查。根据当代指南，患者接受了全面的二维超声心动图检查。将结果与公认的健康受试者参考值进行比较。结果：与指南相比，HTx 患者的心房尺寸更大。左心室（LV）舒张期容积变小，左心室壁厚度增加。就 LV 功能而言，射血分数 ( 62 +/- 7%, P
Background: Heart function following heart transplantation ( HTx) is influenced by numerous factors. It is typically evaluated using transthoracic echocardiography, but reference values are currently unavailable for this context. The primary aim of the present study was to derive echocardiographic reference values for chamber size and function, including cardiac mechanics, in clinically stable HTx patients.Methods: The study enrolled 124 healthy HTx patients examined prospectively. Patients underwent comprehensive two-dimensional echocardiographic examinations according to contemporary guidelines. Results were compared with recognized reference values for healthy subjects.Results: Compared with guidelines, larger atrial dimensions were seen in HTx patients. Left ventricular ( LV) diastolic volume was smaller, and LV wall thickness was increased. With respect to LV function, both ejection fraction ( 62 +/- 7%, P
