Acute myocardial infarction in twin pregnancy after assisted reproduction: A case report.

BACKGROUND

Acute myocardial infarction (AMI) during pregnancy is rare, especially in twin pregnancy, and it can endanger the lives of the mother and children. Except for conventional cardiovascular risk factors, pregnancy and assisted reproduction can increase the risk of AMI during pregnancy. AMI develops secondary to different etiologies, such as coronary spasm and spontaneous coronary artery dissection.

CASE SUMMARY: A 33-year-old woman, with twin pregnancy in the 31st week of gestation, presented to the hospital with intermittent chest tightness for 12 wk, aggravation for 1 wk, and chest pain for 4 h. Combined with the electrocardiogram and hypersensitive troponin results, she was diagnosed with acute ST-elevation myocardial infarction. Although the patient had no related medical history, she presented several risk factors, such as age greater than 30 years, assisted reproduction, and hyperlipidemia. After diagnosis, the patient received antiplatelet and anticoagulant treatment. Cesarean section and coronary angiography performed 7 d later showed stenosis and thrombus shadow of the right coronary artery. After receiving medication, the patient was in good condition.

CONCLUSION

This case suggests that, with the widespread use of assisted reproductive technology, more attention should be paid to perinatal healthcare, especially when chest pain occurs, to facilitate early diagnosis and intervention of AMI, and the etiology of AMI in pregnancy needs to be differentiated, especially between coronary spasm and spontaneous coronary artery dissection.
