新生儿窒息后的低氧血症可引起全身多脏器功能的损害,心脏是常受到损害的重要器官之一。在临床上急性颅脑损伤后也极易出现继发性心脏损害,因此,它常与中、重度新生儿缺氧缺血性脑病(HIE)合并存在,并导致心功能不全,引起脑灌注减少,又进一步加重脑损伤,使病情加重。国内文献报道新生儿窒息合并心肌损伤发生率为40%~78%[1,2]。新生儿心肌细胞修复和再生能力较强,早期诊断 Hypoxemia after neonatal asphyxia can cause damage to systemic multiple organ function, the heart is often one of the important organs damaged. It is also prone to secondary cardiac damage after clinical acute craniocerebral injury. Therefore, it often coexists with moderate and severe neonatal hypoxic-ischemic encephalopathy (HIE) and leads to cardiac insufficiency, resulting in decreased cerebral perfusion , Further aggravate brain injury, aggravating the condition. Domestic literature reports neonatal asphyxia with myocardial injury rate of 40% to 78% [1,2]. Neonatal cardiomyocytes repair and regeneration ability, early diagnosis
