Davtyan concurred. "Basically I would not tell people to stop using contraceptives right this moment and I think this would really have to be confirmed."
Rather, Rietzschel added, women should become more aware of other lifestyle factors that they can change in order to lower their overall risk of heart disease.
"The implications are that you shouldn't suddenly stop taking [oral contraceptives], no reason to panic, but look at your risk factors," he said. "Is there something you can do to prevent heart disease in the future? Avoid obesity, stop smoking, be physically active, et cetera.
"So don't stop taking the pill, but limit the risk of heart disease through primary preventive measures we all need to take."
