A comprehensive study analyzing over 56,000 pregnancies over two decades reveals a troubling rise in cardiovascular complications. Experts highlight the need for proactive health care to ensure the well-being of mothers and babies.
Cardiovascular-related health problems may occur in as many as one out of every seven pregnancies, according to new research published today in the journal Circulation. This troubling trend highlights the need for enhanced health care measures before, during and after pregnancy.
A comprehensive review of more than 56,000 pregnancies from 2001 to 2019 within the Mass General Brigham health care system in New England revealed a steady surge in cardiovascular complications.
These complications, including heart attacks, strokes, heart failure, blood clots, hypertensive disorders and maternal deaths, affected approximately 15% of the pregnancies reviewed.
The increase was most pronounced among those with pre-existing cardiovascular conditions but was observed across all age groups and even among those without prior health issues.
Several health risk factors prevalent before and during pregnancy played a crucial role in this rise. For instance:
- Obesity rates increased from 2% in 2001 to 16% in 2019.
- High blood pressure increased from 3% to 12%.
- High cholesterol increased from 3% to 10%.
- Diabetes increased from 1% to 3%.
“Most of these health risk factors can be prevented through lifestyle changes or medication. Yet, many of my patients aren’t even aware they have these conditions or that they’re at risk,” Stacey E. Rosen, volunteer president of the American Heart Association and senior vice president of women’s health and executive director of the Katz Institute for Women’s Health of Northwell Health in New York City, said in a news release.
“If you’re planning to become pregnant, I strongly encourage you to connect with a clinician early to understand your risks and take steps to reduce them. During pregnancy, stay proactive about your health. Listen to your body and your provider to address any concerns that arise. And don’t overlook the postpartum period, which also carries important health considerations. Starting before pregnancy and continuing after birth, there are valuable opportunities to make heart-healthy choices that can help prevent cardiovascular disease and support long-term wellness.”
This study underscores the importance of engaging with health care providers at every stage of pregnancy. Proactive measures, such as understanding personal health risks and making heart-healthy choices, can mitigate many of these complications.
