Heart Disease: Linked to Dementia

A recent NIH-funded study suggests that middle-aged people with risk factors for cardiovascular disease, including heart attacks and stroke, are more likely to develop dementia in old age than people without vascular risk factors.

The study, published in JAMA Neurology, included factors like diabetes, high blood pressure and smoking. “With an aging population, dementia is becoming a greater health concern. This study supports the importance of controlling vascular risk factors like high blood pressure early in life in an effort to prevent dementia as we age,” said Walter J. Koroshetz, MD, director of NIH’s National Institute of Neurological Disorders and Stroke.

Reducing Inflammation Lowers Risk of Heart Attack

It turns out that cholesterol isn’t the only thing you have to worry about to keep your heart healthy. In recent years, doctors have started to focus on inflammation — the same process that makes cuts red and painful — as an important contributor to a heart attack. It’s the reason doctors recommend low-dose aspirin to prevent recurrent heart attacks in people who have already had them, why they also prescribe statins, which lower both cholesterol and inflammation, and why they have started to measure inflammation levels in the blood.

But it’s never been clear exactly how much inflammation adds to heart disease risk. Since statins lower both, it’s hard to tell whether inflammation or cholesterol has the bigger impact on heart problems.
