Hitting the activity mark

Common activity guidelines recommend a minimum of 150 minutes of moderate-intensity physical activity and two muscle-strengthening workouts per week. However, these targets are meant for a broad population, and for many older adults, hitting just the 150 minutes per week poses a challenge. Experts suggest breaking down the 150 minutes into manageable segments, like doing 30 minutes of activity five days a week, and even dividing those 30 minutes into 10 minutes of exercise three times a day.

Is calcium in my diet bad for my heart?

Calcium deposits in the coronary arteries surrounding the heart may be a sign of fatty plaque buildup in arteries. Dietary calcium is not a cause of these calcium deposits. While people can’t reverse the effect of calcium deposits, they can slow the process by managing blood pressure and “bad” LDL cholesterol.

Are you eating enough protein?

Strength training and protein are two ways to combat age-related muscle loss, known as sarcopenia. Muscles need protein to help fuel new growth and maintain mass. However, many aging men don’t consume enough protein and may need more than the usual recommended daily intake. To get more protein, men can start by tracking their daily protein consumption and then making dietary adjustments, such as choosing high-quality protein foods, spreading protein across daily meals, and using protein powders as needed.

An inside look at aortic stenosis

Aortic stenosis occurs when the heart’s aortic valve becomes stiff and calcified, narrowing its opening so blood cannot flow normally. This can cause symptoms such as shortness of breath, fatigue, lightheadedness, fainting, and chest tightness. Neither lifestyle nor medications can slow or reverse aortic stenosis. People born with a bicuspid aortic valve are at high risk, but most people with aortic stenosis have a normal appearing valve. The only treatment is to replace the damaged valve using open heart surgery or a less invasive, nonsurgical approach called transcatheter aortic valve implantation.

Dietary salt and blood pressure: A complex connection

About a third of healthy people—and about 60% of people with high blood pressure—are salt sensitive, meaning they have an exaggerated response to dietary sodium. But an estimated one in 10 people may have inverse salt sensitivity: their blood pressure goes up when they eat less salt. Understanding the genetic basis of these differences may one day improve the treatment of blood pressure.

Gene therapy for cardiovascular disease

Clinical trials are under way using gene therapy to treat inherited cardiovascular conditions, including familial hypercholesterolemia (one form of abnormally high cholesterol), hypertrophic cardiomyopathy (a type of heart muscle disease), and transthyretin amyloid cardiomyopathy (a form of heart failure resulting from amyloid deposits). But challenges remain in developing and delivering these therapies.
