Key result
Maternal cardiovascular changes are linked to serious complications like cardiomyopathy and CAD lacking specific treatments.
Why the study?
Specific treatments for cardiovascular complications of pregnancy are lacking, and rising maternal mortality in the United States highlights the need to understand the underlying molecular mechanisms and pathology.
Highlights the critical need to understand molecular mechanisms driving cardiovascular complications during pregnancy given the rising maternal mortality rate and lack of specific treatments.
No specific treatments for pregnancy cardiomyopathy or CAD; leaves open mechanistic studies amid rising maternal mortality.
The maternal cardiovascular system undergoes dramatic remodeling in response to the stresses of pregnancy. Although in most cases these changes are temporary and well tolerated, in others they can give rise to complications, including cardiomyopathy, coronary artery disease, and hypertensive cardiovascular disease. Despite an increasing number of preclinical models to study these diseases, specific treatments for any of these pregnancy complications are lacking. As the maternal mortality rate is rising in the United States, it is critical to understand the molecular mechanisms driving cardiovascular changes during pregnancy, and the pathology that can result.
