Are Heart Attack Survivors Neglecting LDL Cholesterol Risk?

70% of individuals who have experienced heart attacks and strokes are not aware that LDL cholesterol is commonly known as 'bad cholesterol,' stated a recent survey conducted by The Harris Poll on behalf of the American Heart Association in 2023 (1^✔ ✔Trusted Source

American Heart Association Survey Results

• 75% of heart attack and stroke survivors reported having high cholesterol.
• Survey shows 47% of heart attack and stroke survivors are unaware of their LDL cholesterol number.

The survey, conducted on behalf of the Association, the world’s leading voluntary organization dedicated to building healthier lives for all, found that 75% of heart attack and stroke survivors reported having high cholesterol. However, only 49% recognized the need to prioritize lowering their cholesterol. “There’s a pervasive lack of public awareness and understanding around bad cholesterol and its impact on your cardiovascular health. As bad cholesterol usually has no symptoms, we often find that many patients are walking around without knowing they’re at risk or how to mitigate it,” said Joseph C. Wu, MD, PHD, FAHA, American Heart Association volunteer president and director, Stanford Cardiovascular Institute and Simon H. Stertzer, MD, Professor of Medicine & Radiology at Stanford School of Medicine.

Through its Lower Your LDL Cholesterol Now™ initiative, sponsored nationally by Amgen Inc., the American Heart Association is encouraging people to ask their doctor to check their cholesterol levels. In the Harris Poll study, 98% of heart attack and stroke survivors surveyed say they are willing to take a simple blood test if recommended by their health care professional.

"What's eye-opening about these survey results is that nearly half of those who have suffered a heart attack or stroke don’t know their LDL cholesterol levels, which is a vital step in helping to prevent a second heart attack or stroke," said Paul Burton, M.D., Ph.D., senior vice president and chief medical officer, Amgen. “Amgen is committed to working with other health care leaders, like the American Heart Association, to empower people to know more and do more about their cardiovascular disease. For patients, this starts with talking to your doctor about your LDL cholesterol number and appropriate steps for testing and treatment.”

Among those who have experienced a heart attack and/or stroke, 69% say they have heard of LDL cholesterol. However, a substantial proportion (47%) remain unaware of their LDL number. LDL cholesterol (2^✔ ✔Trusted Source

American Heart Association's Cholesterol Check Recommendations

“At the American Heart Association, we recommend that all adults 20 or older should have their cholesterol checked every 4 to 6 years as long as their risk remains low. After age 40, your health care professional will also want to use an equation to calculate your 10-year risk of having a heart attack or stroke. People who have had a prior heart attack or stroke may need their cholesterol checked more often,” said Donald M. Lloyd-Jones, M.D., Sc.M., FAHA, past volunteer president of the American Heart Association and chair of the department of preventive medicine, the Eileen M. Foell Professor of Heart Research and professor of preventive medicine, medicine and pediatrics at Northwestern University’s Feinberg School of Medicine in Chicago. “This is very much a case where knowledge is power. The more you know, the more you can do to decrease your risk of heart attack and stroke in the future.”

“However, there's still progress to be made,” emphasizes Lloyd-Jones, ”as this statistic underlines that a considerable portion of survivors require further understanding, particularly regarding the specific risk associated with LDL cholesterol. It's essential for heart attack and stroke survivors to grasp the profound impact of high LDL cholesterol, often referred to as the ‘bad’ cholesterol, on their cardiovascular health.”
