For people who have previously had a heart attack, taking a daily aspirin could reduce their risk of a repeat cardiac event or stroke, according to a recent Danish study.The findings were presented at the ESC Congress 2023 in Amsterdam this week.”Our findings support current clinical guidelines on aspirin therapy following myocardial infarction (heart attack),” said study author Dr. Anna Meta Kristensen of Bispebjerg and Frederiksberg Hospital in Denmark, in a statement provided to Fox News Digital.‘LAUGHTER THERAPY’ IS SHOWN TO REDUCE HEART DISEASE RISK IN BRAZILIAN STUDY: ‘EXCITING TO SEE'”The key takeaway of our study is that patients who are non-adherent to aspirin therapy following myocardial infarction have an increased risk of a composite outcome consisting of recurrent myocardial infarction, stroke or death compared with adherent patients,” she went on.”However, the protective effect of aspirin appeared to decrease slightly over time from four years after myocardial infarction and onwards.” For people who have previously had a heart attack, taking a daily aspirin could reduce their risk of a repeat cardiac event or stroke, according to a recent Danish study.

It does pose a risk of bleeding, however. “Our findings support current clinical guidelines on aspirin therapy following myocardial infarction (heart attack),” said study author Dr. Anna Meta Kristensen.

Those who did not continue taking the aspirin had a 29% higher risk of a recurrent heart attack, stroke or death at two years. The risk increased to 40% at four years, to 31% at six years and 20% after eight years.

Tobin)”For decades, cardiologists have recommended daily low-dose aspirin — which is usually 81 mg in the U.S.,” he told Fox News Digital. “This has resulted in a reduction of subsequent heart attacks or any cardiovascular events.”What did change in the revised guidelines a few years ago was that aspirin is no longer recommended as “primary prevention.” The American Heart Association recommends low-dose daily aspirin for people who have underlying vascular diseases, such as coronary artery disease or peripheral artery disease, or who have had a stroke or heart attack.CLICK HERE TO SIGN UP FOR OUR HEALTH NEWSLETTER”This guidance is called ‘secondary prevention,’ and it has never changed,” von Schwarz said. “If someone had a heart attack or a stent placed in the past, this patient should stay on daily low-dose aspirin lifelong.”What did change in the revised guidelines a few years ago was that aspirin is no longer recommended as “primary prevention,” he said. The American Heart Association recommends low-dose daily aspirin for people who have underlying vascular diseases, such as coronary artery disease or peripheral artery disease, or who have had a stroke or heart attack. (iStock)”This means we no longer give aspirin to individuals just because they have risk factors for cardiovascular diseases — such as a combination of diabetes, high blood pressure and high cholesterol,” the doctor noted. The guidelines changed due to the risk of bleeding in the gastrointestinal tract as a result of aspirin use, von Schwarz pointed out.CLICK HERE TO GET THE FOX NEWS APP”This risk can be reduced by taking aspirin with food but not on an empty stomach, preferably at dinner time, which is supposed to reduce the risk of heart attacks and strokes that oftentimes occur in the early morning hours,” he said.
