Pregnancy outcome in a mother with alcoholic cardiomyopathy

Management of the Cardiovascular Complications of Substance Use Disorders During Pregnancy

PURPOSE OF REVIEW

Substance use disorder in pregnancy and subsequent cardiovascular complications are on the rise in the USA. The care of pregnant women with substance use disorder is complex, and requires a thorough understanding of mechanisms of action, pathophysiology, and cardiovascular response during pregnancy. The goal of this review is to provide information about the most common drugs of abuse in pregnancy and to recommend management guidelines.

RECENT FINDINGS

Pregnant women with substance use disorder are at increased risk of significant cardiovascular complications, both as a direct effect of acute intoxication as well as the secondary risk from infection and cardiotoxicity associated with chronic use. This risk must be considered in the antepartum management, delivery, and postpartum periods. Understanding the increased cardiovascular risk of pregnant women with substance use disorder, as well as specific drug interactions, anesthesia considerations, best practices, and management considerations, is important for all clinicians caring for this population.

Dilated Cardiomyopathy in Pregnancy: Outcomes From an Australian Tertiary Centre for Maternal Medicine and Review of the Current Literature

BACKGROUND

Peripartum cardiomyopathy is associated with significant risks of decline in left ventricular function and adverse maternal and fetal outcome in subsequent pregnancy. The risks of pregnancy in women with dilated cardiomyopathy are unclear. We aimed to assess the outcome of pregnancy in women with dilated cardiomyopathy seen at our institution and to review the literature on this subject.

METHODS

A retrospective audit of the outcomes of 14 pregnancies to 12 women with dilated cardiomyopathy.

RESULTS

There were no cardiac events and no woman had a decline in left ventricular function during pregnancy. There was a high rate of prematurity and adverse fetal outcome related to this, including four neonatal deaths.

CONCLUSION

Maternal outcomes in this small series were satisfactory though only three women had moderate-severe left ventricular dysfunction at baseline. There was a high rate of premature delivery and adverse neonatal outcome.
