Cardiac disease in the equine neonate occurs infrequently. Murmurs are often heard in foals and are not considered significant unless they persist beyond 4 days of age. Congenital cardiac defects are the most common form of primary cardiac disease in the foal, with ventricular septal defects occurring most frequently. Other neonatal foal diseases such as ruptured bladders, white muscle disease, neonatal respiratory distress syndrome, and septicemia have secondary cardiac involvement.
马驹患心脏病的情况并不常见。在幼驹中经常能听到心脏杂音，除非杂音在4日龄后仍持续存在，否则一般不被认为是严重问题。先天性心脏缺陷是马驹原发性心脏病最常见的形式，其中室间隔缺损最为常见。其他新生马驹疾病，如膀胱破裂、白肌病、新生儿呼吸窘迫综合征和败血症，也会继发心脏问题。
