Family history foretells early heart disease

It is commonly understood that when a parent has died of heart disease at a young age (under 60), the offspring have a higher risk of having heart disease.

 

A recent study, which examined data on millions of people in Denmark over a period of 30 years, confirms this theory. In fact, the risk is also increased for individuals with a second-degree relative (grandparent, half-sibling) who died young.

 

And the risk can be compounded-- when two or more first-degree relatives died of heart problems before age 60, a person's own risk of early heart disease rose five-fold.

 

It's important to note that the power of lifestyle changes to offset this potential is not clear. So, while the risk may be increased for individuals with a family history, there is still a very likely benefit to making improvements in blood pressure, cholesterol, exercise, and diet. The increased risk should be used as information and perhaps inspiration to make improvements, but not as a foregone lifespan conclusion.

People on calorie restriction have better heart rate variability

People who restrict their caloric intake in an effort to live longer have hearts that function more like those in people who are 20 years younger.

Researchers at Washington University School of Medicine in St. Louis have found that a key measure of the heart's ability to adapt to physical activity, stress, sleep and other factors that influence the rate at which the heart pumps blood, doesn't decline nearly as rapidly in people who have significantly restricted their caloric intake for an average of seven years.
