Women’s Health: How Mammograms Can Reveal Cardiovascular Disease

The routine mammograms women receive to check for breast cancer may also offer clues to their risk for heart disease, new research suggests.

White spots or lines visible on mammograms indicate a buildup of calcium in breast arteries. This breast arterial calcification is different from coronary artery calcification, which is known to be a marker for higher cardiovascular risk. For the study, researchers followed 5,059 postmenopausal women (ages 60 to 79) for six and a half years. They found that those with breast arterial calcification were 51% more likely to develop heart disease or have a stroke than those without calcification. The study was published March 15, 2022, in Circulation: Cardiovascular Imaging.

Studies: ‘Coffee’ – Machine Learning Review Shows Benefits Of Drinking It

“It may be good for you,” says Dariush Mozaffarian, dean of the Friedman School of Nutrition Science and Policy at Tufts University. “I think we can say with good certainty it’s not bad for you.” (Additives are another story.)

After the link appeared between coffee intake and a reduced risk of heart failure in the Framingham data, Kao confirmed the result by using the algorithm to correctly predict the relationship between coffee intake and heart failure in two other respected data sets. Kosorok describes the approach as “thoughtful” and says that it “seems like pretty good evidence.”

Should you drink coffee? If so, how much? These seem like questions that a society able to create vaccines for a new respiratory virus within a year should have no trouble answering. And yet the scientific literature on coffee illustrates a frustration that readers, not to mention plenty of researchers, have with nutrition studies: The conclusions are always changing, and they frequently contradict one another.
