Women who experience depression during pregnancy or after birth have higher risk of cardiovascular disease

Research published in the European Heart Journal found that women diagnosed with perinatal depression are more likely to develop cardiovascular disease. The study included data from around 600,000 women and found a strong link between perinatal depression and risks of high blood pressure, ischemic heart disease, and heart failure.

Fewer than 1 in 4 patients receive dietary counseling after a heart attack

A study by the University of Michigan Health Frankel Cardiovascular Center found that only 23% of heart attack patients received dietary counseling within 90 days of hospitalization. Nutrition counseling, often provided by registered dietitian nutritionists, may reduce cardiovascular risk for patients.
