But previous studies in the U.S. have not looked at how they affect different sexes and races, said Elsayed Z. Soliman, M.D., the study’s senior author and director of the Epidemiological Cardiology Research Center at Wake Forest Baptist Medical Center in Winston-Salem, North Carolina.
A key takeaway from the results, Soliman said, is that prevention of heart attacks should take into account sex and race. Women with cardiovascular disease, for example, may require different treatment strategies and medications than men.
“One size doesn’t fit all,” Soliman said.
Even so, the finding that women who have a silent heart attack are more likely than men to die needs to be confirmed, said Michael D. Shapiro, M.D., a cardiologist who specializes in cardiac imaging.
“You can’t make a definitive conclusion from the data they have here,” he said, adding that larger studies with more reported heart attacks are needed to know whether the finding is real.
Shapiro, an associate professor at Oregon Health & Science University, said the new research is still important because it is one of the few to look at race and gender differences in silent heart attack and its long-term effects on cardiovascular health.
A heart attack occurs when the blood flow to the heart is significantly reduced or cut off completely because of a clogged artery. Silent heart attack symptoms can appear so mild that they are barely noticed, if at all. They are detected later, usually when patients undergo an electrocardiogram to check their heart’s electrical activity, researchers said.
Silent heart attacks, once discovered, should be treated as aggressively as heart attacks with symptoms, Soliman said. In the new study, the rate of heart attacks with symptoms was higher in men than women.
Risk factors such as high cholesterol, diabetes and high blood pressure — which are the same for both types of heart attacks — must also be treated, he said. “[People] need to control the risk factors and follow up with their doctors.”
