Study suggests women to focus on their heart's wellbeing before getting pregnant

Illinois [US], February 15 (ANI): Pregnancy stresses a woman's heart and circulatory system. During pregnancy, a lady's blood volume increases by 30 to 50 per cent to nourish her growing baby. A new Northwestern Medicine study shined a spotlight on an important but often overlooked matter of the heart -- optimising one's cardiovascular health before getting pregnant.
The study was published in 'Circulation', the American Heart Association's (AHA) peer-reviewed flagship journal, as part of a themed issue for the Go Red for Women Campaign that was developed by the AHA in 2004 to highlight awareness about heart disease risks in women.
More than one in two young women between the ages of 20 and 44 who gave birth in the United States in 2019 had poor heart health before becoming pregnant, the study found. Poor heart health put expectant mothers and their babies at risk, with heart disease, was causing more than one in four pregnancy-related deaths.
"As women, we tend to think about the baby's health once we become pregnant, but what so many women don't realize is the very first thing they can do to protect their babies (and themselves) is to get their heart in shape before they even conceive," said senior study author Dr Sadiya Khan, assistant professor of medicine in cardiology and epidemiology at Northwestern University Feinberg School of Medicine and a Northwestern Medicine physician.
More than half the women in the study had at least one risk factor for poor heart health, including overweight/obesity, hypertension or diabetes before becoming pregnant. Being overweight or obese was the most common reason for poor heart health before pregnancy, the study found.

"Women with favorable heart health before pregnancy are less likely to experience complications of pregnancy and are more likely to deliver a healthy baby," said lead study author Dr. Natalie Cameron, an internal medicine specialist and instructor at Feinberg and a Northwestern Medicine physician. "Even more importantly, optimizing heart health before and during pregnancy can prevent the development of heart disease years later. Clinicians can play a key role in both assessing and optimizing heart health prior to pregnancy."
The scientists compared data by geographical region and even as good heart health was declining overall across the country, there were geographic differences. The percentage of women with good heart health was lower in South (38.1 per cent) and Midwest (38.8 per cent) states, compared with states in the West (42.2 per cent) and Northeast (43.6 per cent). There were also variations among states, ranging from less than one-third of women in Mississippi (31.2 per cent) having good heart health prior to pregnancy compared to nearly half (47.2 per cent) in the best U.S. state: Utah.
"The geographic patterns observed here are, unfortunately, very similar to what we see for heart disease and stroke in both women and men," Khan said. "They indicate factors, such as social determinants of health, play a critical role in heart health as well as maternal health."
"Pregnancy is often described as a window to future heart health, and taking the opportunity to leverage the prenatal period to optimize maternal heart health is critical. But we also need to focus on optimizing cardiovascular health throughout young adulthood because nearly half of pregnancies are unplanned. We need to emphasize heart health across the life span."
The scientists encouraged women to see a doctor or other health care clinician prior to becoming pregnant to take active steps to maintain a healthy lifestyle before and during pregnancy. This involves staying physically active, eating a healthy diet filled with vegetables, whole grains and plant-based proteins, and avoiding tobacco to reduce the risks of being overweight or having high blood pressure or diabetes.
