People who are married have lower rates of several cardiovascular diseases compared with those who are single, divorced or widowed, according to research to be presented at the American College of Cardiology's 63rd Annual Scientific Session. The relationship between marriage and lower odds of vascular diseases is especially pronounced before age 50. 

"These findings certainly shouldn't drive people to get married, but it's important to know that decisions regarding who one is with, why, and why not may have important implications for vascular health," said Carlos L. Alviar M.D., cardiology fellow, New York University Langone Medical Center, and the lead investigator of the study. Researchers prospectively analyzed records from a database of more than 3.5 million people nationwide who were evaluated for cardiovascular diseases. Patients' demographic information and cardiovascular risk factors were obtained, and researchers estimated the odds of disease by marital status after analyzing the presence of vascular disease in different blood vessel locations such as the coronary arteries, leg arteries, carotids and the abdominal aorta. Traditional cardiovascular risk factors such as hypertension, diabetes, smoking and obesity were similar to the overall U.S. population, according to authors. The odds of coronary disease were lower in married subjects compared with those who were widowed and divorced, but this was not statistically significant when compared to single subjects, which were used as the reference group for comparison.
