To assess possible changes in myocardial contractile function and relaxation occurring after mild perinatal asphyxia, maximal blood pressure and M-mode echocardiograms should be registered simultaneously in 32 normal term newborns (group 1) and in 22 term asphyxiated newborns (group II). The slope of end-systolic pressure-dimension relation (ESPDR) was used as a reliable index for evaluation of the myocardial contractility. The slope of ESPDR and some indices of ventricular relaxation decreased in newborns from group II. It is suggested that ESPDR and parameters of left ventricular relaxation and filling can serve as early and sensitive indices of hypoxic myocardial damage.
为评估轻度围产期窒息后心肌收缩功能和舒张功能可能发生的变化，应同时记录32名足月正常新生儿（第一组）和22名足月窒息新生儿（第二组）的最大血压和M型超声心动图。收缩末期压力-维度关系（ESPDR）的斜率被用作评估心肌收缩力的可靠指标。第二组新生儿的ESPDR斜率和一些心室舒张指标降低。提示ESPDR以及左心室舒张和充盈参数可作为缺氧性心肌损伤的早期敏感指标。
