Cardiac dysfunction is a rare complication of babesiosis in domestic animals. The horse in this report showed clinical signs of anorexia, depression, fever, icterus and brown urine, and laboratory results (monocytosis, thrombocytopenia, azotemia, hyperbilirubinemia and bilirubinuria) indicated sub-acute piroplasmosis. Furthermore, junctional and polymorphic ventricular premature complexes and tachycardia associated with increased serum cardiac troponin I and myocardial-bound creatine kinase concentration were found. The diagnosis of piroplasmosis was confirmed by serology. Specific and supportive therapy for babesiosis allowed remission of clinical signs and laboratory profile abnormalities, including those of myocardial involvement. Myocardial damage associated with cardiac arrhythmia may be a complication of equine babesiosis as already demonstrated in other species.
心脏功能障碍是家畜巴贝斯虫病的一种罕见并发症。本报告中的马表现出厌食、抑郁、发热、黄疸和棕色尿液等临床症状，实验室检查结果（单核细胞增多、血小板减少、氮质血症、高胆红素血症和胆红素尿）表明为亚急性梨形虫病。此外，还发现了交界性和多形性室性早搏复合体以及与血清心肌肌钙蛋白I和心肌结合肌酸激酶浓度升高相关的心动过速。梨形虫病的诊断通过血清学得到证实。针对巴贝斯虫病的特异性和支持性治疗使临床症状和实验室检查异常（包括心肌受累的异常）得到缓解。与心律失常相关的心肌损伤可能是马巴贝斯虫病的一种并发症，正如在其他物种中已经证实的那样。
