Women tend to downplay their symptoms and delay seeking treatment. But health care providers may be contributing to this problem, too A major underlying issue may be the underrepresentation of women in clinical trials of heart-related conditions.

Too much or too little potassium can harm the heart. Diet, medications, and kidney function can affect the body's potassium level. Dietary potassium helps keep blood pressure in a normal range, but most Americans don't consume enough of this mineral. However, people taking medications that raise potassium levels—which includes certain drugs to treat high blood pressure and heart failure—should avoid salt substitutes made with potassium chloride.

An analysis shows less than 7% of adults in the US meet the criteria for optimal cardiometabolic health. Taking small steps to help control and improve key risk factors can reduce the odds of a heart attack or stroke.

A randomized trial published May 14, 2022, in The Lancet found that people with heart disease who ate a Mediterranean diet for seven years had a 26% lower risk of having a heart attack or stroke, compared with people who ate a low-fat diet.

Seven factors appear to account for most first heart attacks in people ages 55 and younger: diabetes, depression, high blood pressure, current smoking, family history of early heart attack, low household income, and high cholesterol.

People who don't regularly get at least seven hours of sleep a night should assess their daily habits to look for ways to improve, such as by establishing an earlier bedtime and turning off all electronic devices at least an hour before bedtime.

Recent guidelines suggest a blood pressure reading of less than 120/80 mm Hg as normal. But the ideal number for individuals depends on their individual goals and whether they also have a chronic condition, such as heart disease or kidney disease.

A 2022 study found that people who have depression after a heart attack are nearly 50% more likely to suffer a stroke compared with heart attack survivors who don't develop depression.
