Silent heart attacks often go unnoticed because they don't produce any symptoms or only mild symptoms that are mistaken for something else, such as heartburn or muscle pain. They are thought to make up from 20% to 60% of heart attacks and can raise risk of a future heart attack or related problem. Both women and men are at substantial risk. Making lifestyle changes and being proactive about managing risk factors for heart disease can help prevent future heart-related problems.

A buildup of fat inside the liver, known as nonalcoholic fatty liver disease (NAFLD) affects about 25% of adults. This under-recognized condition is closely linked to obesity (especially excess weight around the middle of the body), type 2 diabetes, and cardiovascular disease. People with NAFLD can slow or even reverse the condition with the same lifestyle strategies that improve cardiovascular health: losing weight, adopting a healthy diet, and exercising regularly.

The typical American diet isn't very healthy, and dietary shortfalls are more pronounced among people living in lower-income neighborhoods. A study analyzing data from produce prescription programs suggests that improving access to fresh vegetables and fruits may improve heart health.

People who get migraines with aura have a slightly higher risk of heart attack, stroke, or death from cardiovascular disease than people who get migraines without aura or no migraines. But migraines are most common in younger women, whose baseline risk of cardiovascular problems is very low in the first place. Still, those who get migraine with aura should be sure to tell their primary care provider or gynecologist. Taking estrogen-containing birth control pills or hormone therapy may further raise stroke risk in these women.

The age-related drop in sex hormone levels can cause undesirable symptoms such as hot flashes or a flagging sex drive. Various formulations of estrogen or testosterone can ease those symptoms, but hormone therapy has a mixed record when it comes to cardiovascular safety. A 2023 study suggests that testosterone therapy is safe for men at high risk for heart disease. But women at high risk for heart disease But women at high risk for heart disease considering estrogen-based therapy need to balance menopausal symptom severity versus the greater chance of an adverse cardiovascular problem.

A 2023 study found that most people who are hospitalized for heart failure aren't being referred for cardiac rehabilitation. The rehab is a recommended, medically supervised three-month program (covered by Medicare) that significantly lengthens life.

Tai chi is a gentle, adaptable practice that features flowing movements combined with breathing and cognitive focus. It may be especially helpful for people who are recovering from a heart attack or other medical problems or who have heart failure. Tai chi also can be a gateway to other types of physical activity because the practice may improve balance, reduce the risk of falls, and even help ease lower back pain—a common reason for avoiding exercise.

Older people who take low-dose aspirin every day may be more likely to develop anemia. Aspirin discourages blood clots, but the drug also blocks substances that help maintain and protect the delicate tissue lining the gastrointestinal tract. Long-term aspirin use can damage this protective layer, making bleeding more likely. Minor bleeding can go unrecognized and contribute to anemia, a condition marked by a reduced number of healthy red blood cells. People currently taking aspirin should check with their doctor to see if the practice still makes sense for them.

Troponins, which are proteins found in heart muscle cells, are released in the bloodstream during a heart attack. Other conditions, such heart muscle inflammation and chronic kidney disease, can also cause troponin levels to rise.
