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.

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.

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.

A 2023 study suggests that following a healthy vegan diet may improve cardiometabolic risk factors (such as LDL cholesterol and weight) more than eating even a healthy omnivorous diet.

People whose spouses have high blood pressure may be more likely to have high blood pressure themselves than people whose spouses do not have the condition, according to a 2023 study.

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.

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.

Compared with analog scales, digital scales are more accurate and easier to read. Many smart scales include added features such as smartphone connectivity and body composition estimates.

Tiny mesh tubes called stents, used to prop open heart arteries, can relieve stable angina (chest pain with exertion or emotional stress) in many people with coronary artery disease. But this treatment—which carries a risk of complications and a high cost—should be reserved only for people who don’t get relief from drug therapy. Stents do not prevent future heart attacks or improve survival compared with drug therapy. Angina usually results from arteries that are more than 70% blocked, but most heart attacks occur in arteries that are narrowed by only about 40% or less but harbor plaque that ruptures without warning. The resulting blood clot blocks blood flow, triggering a heart attack.
