Reading A daily aspirin can reduce the risk of a heart attack in three quarters of heart patients by reducing the clumping of platelets. Why aspirin does not protect the other quarter of heart patients, researchers from the University of Maryland have now found out. They suggest that high cholesterol in the blood lowers the effects of aspirin.

"We know that aspirin protects against heart disease, ? says Michael Miller from the University of Maryland Medical Center. "So, we prescribe aspirin to our patients, but they do not really measure the effectiveness. This study shows that aspirin does not always help, especially not in people with high cholesterol. While previous research has linked high cholesterol levels directly to increased platelet adhesion, this is the first time that platelets have been scrutinized in patients with elevated blood lipids and aspirin intakes. Conclusion: "Patients who do not take aspirin may need to use a higher dose or take more aggressive ways to lower cholesterol?" says Miller.
