Five numbers give a thumbnail assessment of overall heart health and what factors people might need to address to lower the risk of a heart attack or stroke. These numbers offer ideal goals for most people, although targets vary for individuals based on age or other health conditions.

For people over 60, aiming for a blood pressure target below 130/80 mm Hg may prevent more cardiovascular problems than aiming for the higher target suggested by some physicians. Some feared that the more intensive treatment required to reach the lower target might cause more adverse side effects (such as dizziness and falls) in older people. But side effects do not appear to differ among people taking intensive versus standard therapy.

Many home blood pressure monitors are not validated for accuracy, which means there's no way to know if information they provide is correct. Relying on inaccurate measurements can affect decisions people make about medical treatment. Fortunately, reliable organizations have developed lists of blood pressure monitors that have demonstrated clinical accuracy. If a blood pressure monitor isn't listed, it's probably not validated.

Pregnancy complications such as gestational diabetes and preeclampsia—marked by high blood pressure that can impair organ function and affect blood vessels—are increasingly tied to higher lifetime cardiovascular risks. Women with these complications face greater odds of heart attack, stroke, and diabetes.

Statin dosages fall into three categories (low, moderate, or high) based on how much the medication can lower LDL. The choice of a statin depends on a person's risk.

People with elevated LDL cholesterol values may be able to reduce their LDL levels by eating more foods that are rich in fiber and lower in saturated fats. High-fiber foods include whole grains, beans, nuts, vegetables, and fruits. Saturated fats are found mainly in meat, cheese, and other high-fat dairy products such as butter, half and half, and ice cream.

Most people with heart conditions can safely play sports if their condition is well managed. Exercise should be reintroduced gradually, and the intensity should be tailored to the individual. Monitoring for warning signs can reduce the risk while preserving the heart health benefits.

The thyroid gland releases hormones that affect the heart. Too little thyroid hormone slows the heart rate and may boost blood pressure and cholesterol levels, while too much can trigger abnormal heart rhythms and high blood pressure.

Takotsubo cardiomyopathy, also called broken-heart syndrome, is a weakening of the left ventricle that is usually the result of severe stress. Its symptoms resemble those of a heart attack, and treatment is usually the same as that for heart failure.
