A twist on the genetic link between Alzheimer’s and heart disease
Alzheimer’s disease often strikes fear in people’s hearts because it gradually erodes a person’s ability to remember, think, and learn. There is no cure, and available treatments alleviate symptoms only temporarily. An estimated 5.3 million Americans currently have Alzheimer’s disease, yet this brain disorder is far less common than heart disease. More than 85 million people in the United States are living with some form of cardiovascular disease or the after-effects of stroke, which also affects brain function.
Many people don’t realize that Alzheimer’s and heart disease share a genetic link: the apolipoprotei...

Decline in dementia rate offers “cautious hope”
“The number of Americans with Alzheimer’s disease and other dementias will grow each year as the size and proportion of the U.S. population age 65 and older continue to increase. The number will escalate rapidly in coming years as the baby boom generation ages.”
2015 Alzheimer’s disease Facts and Figures
Despite these alarming projections, a report from a recent issue of the New England Journal of Medicine (NEJM) offered a few words of encouragement. Researchers from the longstanding Framingham study found that the rate of dementia has declined over the course of three decades.
Framingham researchers had been study...

Reversing the effects of the new anti-clotting drugs
The oral anticoagulant warfarin (Coumadin) became available for prescription in 1954. This anti-clotting drug commanded national attention when President Dwight Eisenhower received the drug as part of his treatment following a heart attack. No other oral anticoagulant was successfully developed and marketed in the United States until 2010.
Warfarin is a dangerous drug. Along with insulin, it is responsible for the most emergency hospitalizations due to adverse drug reactions. Whereas insulin causes low blood sugar, warfarin is notorious for the complication of major bleeding. Warfarin is plagued by hundreds of drug-drug an...

Hidden cancer rarely causes out-of-the-blue clots in the bloodstream
Blood clots can be lifesavers when they form outside the bloodstream to stop bleeding from an injury. But they can wreak havoc when they form inside the bloodstream. A blood clot in a coronary artery can cause a heart attack. One in the brain can cause a stroke.
Blood clots that form in a leg vein cause a problem known as venous thromboembolism, or VTE. If the clot stays in the leg, it can cause swelling or pain. If it breaks away and travels to the lungs, it can cause a potentially deadly pulmonary embolism.
In about half of people who develop a VTE, doctors can identify what caused it. Common causes include an injury; su...

Special MRI scan could identify stroke risk in people with atrial fibrillation
Atrial fibrillation is a heart rhythm disorder that affects millions of people. It can make you feel lousy. Even worse, it can cause potentially disabling or deadly strokes. A special MRI scan may — I stress the “may” — help identify people with atrial fibrillation who are at high risk of having a stroke. This could help many people with this condition to avoid taking warfarin or other clot-preventing medications for life.
A normal heartbeat starts in a cluster of cells called the pacemaker. It sits in the heart’s upper right chamber (the right atrium). These cells generate a pulse of electricity that...

Hospitalization after fainting can do more harm than good
One morning not long ago, my teenage daughter started to black out. After an ambulance ride to our local hospital’s emergency department, an electrocardiogram, and some bloodwork, she was sent home with a follow-up doctor appointment. We got the good news that Alexa is perfectly healthy, but should avoid getting too hungry or thirsty so she doesn’t faint again. And I’m feeling lucky that she didn’t need to be hospitalized, because a research letter in this week’s JAMA Internal Medicine points out that hospitalization for low-risk fainting can do more harm than good.
Doctors use something called th...

Having "the talk" when heart disease runs in the family
When heart disease or stroke runs in a family, it's important to talk about it with children and other close family members. The conversation may be hard, but the payoff—better health for all—can be huge, according to the September 2013 Harvard Heart Letter.
"Knowing your family history is one of most powerful tools we have to guide how we take care of ourselves from a health perspective," says Dr. Paula A. Johnson, professor of cardiology at Harvard Medical School and chief of the Division of Women's Health at Brigham and Women's Hospital. "This is a chance for your children to make changes that will have both...
